Still trying to track down my intake leak which I think to be the cause of crazy high exhaust temps. Yesturday I started messing with the carb insulator. First it had a gasket on the top and bottom of it, still leaked. So I pulled the top gasket off, still leaked. By using carb cleaner and running the engine and spraying around till the idle goes up I think I tracked it down to the bottom gasket. In a moment of pure tiredness I pulled that gasket and put on a thin film of gasket maker. I'll know if it worked tonight when I run it.

So question for ya. Do you guys run gaskets on this thing? When I got the car the PO had just put the carb directly on the intake which I think was giving me pre-ignition issues due to the heat. Are these plastic spacers known to be a leak fest? Is gasket maker a bad idea there?

Oh, and what have you guys done to plug off that area on the lower intake. It's the large opening that has 3 bolts on it. There was a crappy metal panel with a home made gasket on it. I hit that with the gasket maker as well.

Website is looking good!

Never used any other gasket just the heat shiel and I never had any problems on our cars.

Ben, I have had two different carbs on my motor & neither carb had a leak issue. No gaskets required. Is the bottom of your carb or the top of the intake manifold screwed up with a crack or marks or ? My plastic insulator was as smooth as glass on both sides. No carb impression marks or anything. Of course the thing got busted when I toasted the car.

EDIT: Do you have all the holes from the vaccum tubes PLUGED ?

No gaskets and no leaks on mine, and Mazdatrix.com sells a block off plate for what you are looking for.

These high EGT temps are making me nuts. I think I'll bring a couple spare insulators and a couple other intakes with me when I go to the track. I can't really even tell if I fixed anything with my garage testing. I have GIANT jets in the carb right now so if I'm hearing people right it should be running to cool right? Lean is hot, rich is cool, or can you get so rich that it gets hot?

What temps are you seeing?
What size is "giant" ?
Have you checkeed your timing?
Sure your header have no cracks?
Sure your probe(s) and guage(s) are in good working order?

Ben, just because IMHJ you are a neat young man with some principles ;) I'll come on up to Road America early in the morning & see if I have any knowledge to help sort out your hi temp/carb leak issues.

Are you doing a Friday open session if there is an open track day ?

What day/time is your first track session ?

After an on track session what do your plugs look like ?

What is are your EGT's ?

What is your water temp ?

What is our oil temp ?

Who is your carb builder ?

Have you talked to your carb builder about the jet size in the carb ?

EDIT: What float level did your carb builder spec ?

EDIT: What fuel pressure did your carb builder spec ?

If you have the hose clamp type EGT gauges I'll bring mine along so that if required we can side rig up my gauges for test purposes.

No Friday session. Last time I raced with the possible intake leak my temps were over 1700 with the gauge pegged. It's as far as my guage goes! And I know that was after I increased the jets 3 times making large changes without affecting the temps one bit. Also later in that session I got a crack in my header, wonder why? That could of been a result of a little off tracking though. Plugs have actually looked good this whole time strangly enough. I'm pretty sure I got the timing correct but this was back before I made all my latest changes. Other than the exhaust temps and the poor poor performance HP wise the engine seems to run just fine with water temps right around 180. Don't have an oil temp guage I'm afraid.

I believe the carb was made by Petit racing way back before I owned the car. Don't know if there is a Petit racing anymore. It was set up to run with out the insulator and with no return line. I've since put the insulator back on after getting possible pre-ignition issues although a jet size up could of cured that. I was told the insulator is probably a good idea so I'd like to make it work with one to keep the heat away. I've also hooked up the return line again because it just seems to make more sense.

Fuel level in the bowls is right in the middle of the glass.

Probes have been used for 2 race weekends and seem to be working great. They are the hose clamp style.

Never had a spec fuel pressure and never had a fuel pressure regulator, till now! Since I've heard numbers from 2.5 to 3 I thought I would go with 2.75 for a trial.

Although this isn't a Yaw carb I've been trying to set it up like one using all the cool advice on his website. I'll take a look at my books tonight and see what jets I last put in there. I'll take a random guess and go with 195 and 70 something but I'll really need to look to be sure.

Thanks for the assistance guys! I think the first run at RA is around 11:30 on saturday David.

Ben, I've been told by Dave Lemon (owner of Mazdatrix) that if you get your jets big enough that you'll start dumping raw fuel into your exhaust and that your exhaust temperature will go extremely high. This is because the fuel starts burning inside the exhaust manifold. If everything else is right, that may be your current issue. On the other hand, if you drop your jets down to a "normal" size and melt the inside of your engine, you didn't hear this from me. :lol:

ddewhurst
08-09-2005, 07:25 PM
Ben & folks, if the header temp is over 1700* with the heat coming out of the motor (not burning excess gas in the header) is it normal for the water temp to be at only 180* ?

How far are the thermocouples from the header face ?

Ben, my Westech temp gauge goes to 1950*.

Shall I bring my Yaw carb (still thinking about getting another one from another place) which I know is a worker ? Do you have a good pressure regulator & a good pressure gauge ?

Do you have an extra crew space ? I like cheep & I work for free. Do you get two practice & qualifying sessions on Saturday along with an Emergency session before the race ?

benracin
08-10-2005, 12:02 AM
That's a good question David, and I have no idea what the answer is. My only guess is that maybe the engine is actually happy up there but then I don't understand why 3 seconday jet changes (160,165,170 I think) plus a change on the primaries haven't made a dent in those temps.

I forgot to mention that I have a spankin' new ISC header and exhaust, so no header cracks.

Thermocouples are approx 14"-16" from the engine.

Jets are 95 and 170. Anyone know what "normal racing carb" is?

And thanks a ton for the offer of the carb and crew David but I'd really love to make my carb work and I'm all full of crew at around nine at the last count. Feel free to stop by though! The weekend goes practice - race Saturday, then practice - race Sunday.

I've been working on my jet changing speed so I'm considering changing jets during a pit stop with the help of my awesome crew. Just an idea though.

Pressure guage is a Holley 1-4 psi I think and the gauge is a very nice one (thanks again for the advice David).

I've only been able to garage test the temps so far so here's a good question. In the racing environment where the secondaries will be open much more often then in my garage, will that extra shot of fuel help cool things down, or does the extra does of air as well as the fuel keep everything about the same?

Help you magic carb wizards! Oh, and thanks.

Marcus Miller
08-10-2005, 02:16 AM
Here are my thoughts, in no particular order, based on my experience in pro7. (no header)

Your primary jets are way smaller (depending on temp, between 25-30 numbers) than mine, and your secondaries are way larger (again 25-30). I've heard both sides of the argument, based on which side to run larger/smaller. not sure it ultimately matters. :unsure:

EGT over 1700 is starting to get bad. I would get a digital gauge that reads higher (I love the sigtronic sold by aircraft spruce). Each car combo is different, but I'd be looking more for ~1675 ish, depending on a dyno run to verify where your car with its engine/header/carb/ignition/gauge combo show.

I have run egts from 1550 to 1725 with no change in water temp.

Petit racing is around, doing mostly 3rd gen stuff.
Yaw no longer does carbs, not sure who is the hot ticket these days...

just random thoughts...

FWIW, in Pro7 a reasonable starting point is 125P 155S. My carb ended up closer to 135 145.

Agreed completely! My ITA car is 330 miles away, and I 've never had the carb off it...

I would think with a header, you would be looking at even more fuel....

Ben, ya don't think this is called the Secret Car Club of America for nothing do ya.

I offered you my carb so that you could learn if your issue is with your carb, jets, what ever. I am not a brain surgen :bash_1_: while at the same time I do have some thoughts on what makes a motor get it done. That don't mean I was going to let you take the carb apart & play peek :119: & see :blink: . Ya might have put my carb on your motor & still had issues. Also, had I brought my 1950* EGT readout ya might have found your EGT is 1725* & not an issue. But as someone else stated if ya do some Dyno runs than ya have some know facts & a base line to work from. Those two items would have gained you positive info for sorting out your issues. In my mind $400 for a new carb is cheap as compared to event fees & not eliminating the issues. But then, priority one with me is driving the race car & I only work on the race car because I can't afford to pay someone to do the work.

All I was trying to do is support your effort so that you might get closer to the plastic car. :o

benracin
08-11-2005, 05:54 PM
Not a problem David. Maybe you should bring the whole engine, carb included, and we'll put that in my car for a trial run. Now that would be a comparison! Maybe I'll see you around this weekend for some RAIN FREE racin'. Actually, you can leave the engine at home. Some rain tires would be really nice. It's the one piece I really don't have! :119:

08-11-2005, 09:19 PM
Ben, some good points there. You don't know how far above 1700 you are, so it might not be a huge issue.

I spent the better part of a day chasing issues with my motor (brand new, with ignition changes, attributing the problems to the ignition, and finally eliminating those, I went into the carb...deep! To no avail. I slapped a buddies carb on and bam! problem solved.)
....so, it takes 5 minutes to flip carbs...take Mr. Dewherst up on his fine offer and you will have eliminated a variable on your logic tree.

If the problem remains, you know it's not jetting.

Also, measure the distance vs other cars of your EGTs. Closer is hotter.

Check and double check all the gaskets, carb, intake, and exhaust. I run the gasket on both sides of the phenolic spacer. Use Epoxy or JB Weld on all the holes there.

Ideally, the dyno is your best tuning tool.

Remeber to check total advance, make sure you aren't too aggresive with timing.

Finally, I know that DD doesn't want to give up any trade secrets, but I am sure he will steer you into the right ballpark by giving you at least one part of the puzzle when it comes to jet sizes.

Ben, the motor & trans is hanging on the motor hoist just waiting for the new chassis to be shoved under it. The whole assembly has a :angry: . The new rust free car should be here in a week or two.

Jake, you are correct. :023: I enjoy passing on some of what I know to others to support their race deal. Not everything. <_< Now what I need is for a guy like you to pass on some of what you have learned to me & I&#39;ll filter it to Ben. The trickle effect........... It&#39;s been interesting lately on the Production site. A production guy brought up a thread about the 1st gen RX-7 12A being classed in another class other that E as a non-ported car. In the BS that follows a great friend of yours ;) whose brother you know very well has stated that the Southeast ITA/7 cars are so fast that the non-ported 1st gen RX-7 should be in F Production. A different Southeast guy came along & suggested that just maybe the fast 1st gen&#39;s in the Southeast were not legal. INTERESTING stuff....

08-11-2005, 10:21 PM
DD...I wish I was the grand poobah of knowledge and had something worth passing on! LOL

So, do you have a link on this thread??

sounds like interesting reading.

the question of what a legal IT rotary can actually make comes up often, and the answers are surprising.

I will say this, I would love to have whatever juice the SE guys seem to have in a straight line. I&#39;m working on it, but they are stout down the straihgt, for sure. That said, Mr Dobson, and mr Lukas have their cars moving thru the corners well too.

Well David, if you&#39;re willing to bring your carb, go ahead and bring it buddy. I&#39;m starting to realize that all the stress I&#39;m feeling wondering if this carb will work or not could easily be taken care of by just trying something else and seeing where I need to go. Might be the closest thing I can get to driving an actual well prepared car! So if you&#39;re willing to bring it on over I promise I&#39;ll treat it extra nice for you. I&#39;ll even let you drink some of our beer! None of my race car driver beer though. That&#39;s where I keep my top secret go go juice.

Bill and I are having trouble making up our mind where we&#39;ll be camping, but if I have my way we&#39;ll be through the paddock and pits and take a right at the fancy bathrooms and head down the hill. My crazy ass van should catch your view by then. I won&#39;t turn down your EGT gauge either. :023:

We&#39;ll be on the road tomorrow. Safe weekend and happy racing everyone! Since I&#39;ve taken a lot of info here I&#39;ll be sure to post some results when it&#39;s all over, if David lets me. I&#39;ll probably make half of it up anyway.

I&#39;m assuming Ben is putting you on his list, but if not, I&#39;d be happy to put you on mine. You&#39;d still have to pay the $10 (using all the free ones on the girlfriend and her family), but at least you&#39;d have a way in.

Let me know. We probably won&#39;t be paddocked near Ben, btw.

A second thread which would be of interest to you is the following.

http://www.coloradoscca.org/prodcar/ Race Reports/Post Deleated

Before this post was deleated the Senior Kraftson was posting some interesting stuff about the Senior Cefalo at the Pocono Double. Kraftson deleated this a.m.

I hate when posts get deleted! I have NO idea what is going on with that one..

It&#39;s a good thing that the Prod site requires that you wait for admin approval before allowing you to post so I can cool down!

I will say this...there are a lot of reasons that I WOULD like to race in a national category, such as prod, and there are lots of reasons I would NOT like to as well.

Guys like Basil Adams with his elitist and totally self serving attitude, amongst others are HUGE reasons NOT to get involved. Their total unreasonableness paints their fellow prod drivers in a terrible light. They make so little sense sometimes.....the central big picture point gets stomped all over.

Guys like Matt Weisberg just love the fray, but fail to provide the real facts..he just seems to get all fired up...ADHD stuff! Sadly his claims are based on things that just aint so, and it costs him a lot of integrity.

Honestly, present company excluded, Joe Harlan seems to have a big picture viewpoint and is better balanced.

The idea has merit, but there seems to be some real philosophical issues among the players.

It is ridiculous to fall for the "too fast for X class" argument...just add weight! :rolleyes:

I like the idea of the stock motor, clutch, brakes, IT suspension, maybe a carb..basically an IT7/A car with slicks, with the required Prod items in prod...keeping it simple stupid...LOL

I really think more cars would come out, be able to race without spending buckets of money, and have fun. But it seems like those that have cars don&#39;t like the idea of other guys being abkle to do the same thing cheaper, or simpler. I came away from that thread with a real sense of "we&#39;re better than you" attitude.........

I thought more people racing, having fun, and not spending buckets of money was one of the cornerstones of the SCCA...the place Americans go to CLUB race....

Your new best friend (Basil) will continue with his know it all what&#39;s best for Production attitude while his British tin top sites idle in a garage someplace. Or more correctly stated in his type words. The car is garaged at the ranch....... ;) & Bob & Matt (one of your other best friends) will help him out. :bash_1_:

so, Ben, David was ther a resolution to this?
Last weekend I found myself battling this issue...
Two weekend ago, the egts were higher thna normal, on a hotter day thna normal. I didn&#39;t think much about it, I bumped the FP a bit and swapped in some bigger jets (+5 in primary and 10 in secondary from "normal"). This got me back to my preferred EGT range.

Fast forward to this past weekend, and my EGTs were out of control again,on an even hotter day. Went up 10 in both rimary and secondary. I&#39;m now reptty far from my preferred setup thant dyno`d so nicely.

I&#39;ve checked the insulator, the fuel pressure, the exhaust mounting, etc....
thoughts?

Marcus, on Sat. Ben installed my 1900* EGT gauge & found his temps to be 1700* & 1750*. On Sun. he installed my carb, reg, gauge, ran as fast as he ever had (1st time on a track this year). but the motor died in the loooong 180* R.H. turn/fuel gauge went to zero. Both pick ups were at the right hand side of car. He has a two pump/two pick up system with no check valves. His crew would not allow disconnecting one fule pump/pick up so they filled the tank full :119: for the race & finished second.

It was a successful weekend for Ben.

Marcus, my questions would be:

A. During the two different days & the 1st day temp higher than normal & the 2nd day the temps higher than the 1st day what were the air temps & what were the exhaust temps, water temp, oil temp ?

B. Were your lap times impacted by these temps ?

C. Was the air temp the only difference from the previous time at the track ? (is your air intake bringing in engine bay air or outside outside engine bay air ?)

D. What did your plugs look like ?

The high temp situation has never been an issue for me. We have temps fron 50* in the spring & fall to 100* with high humidity in summer. If this high temp issue bit me in the ass & my lap times were ok or not ok I would try some cooler plugs. When Kart racing the hot/cold plugs make an enormous difference with no carb changes. But at the same time I would adjust the Kart carb full throttle needle valve while racing. Lean out of corners & fat going into corners.

Thoughts from others who have tried cooler plugs under same conditions as Marcus has ?

For mine I think all the checking and double checking of the gasket surfaces and all those little emissions holes paid off. Back when all these problems occured the car was slow as heck. No power at all. I couldn&#39;t even accelerate in 5th gear. So before this last race I checked and checked and checked those surfaces. I ended up going with a nice thin layer of gasket maker on the insulater and no real gaskets. I changed some plastic/rubber caps that looked iffy and something, not sure what, did the trick. On Saturday I used my carb and the car had power again.

Since my EGT gauge wasn&#39;t able to show high temps before all this fixing I&#39;m really not sure what got fixed. I just know that after all the stuff I did the temps were 1700 and 1650 and more importantly, the power was back, big time. I think I&#39;m actually running pretty rich!

damn, my typing sucks.

Marcus, my questions would be:

A. During the two different days & the 1st day temp higher than normal & the 2nd day the temps higher than the 1st day what were the air temps & what were the exhaust temps, water temp, oil temp ?

Day one - normal jetting, water ran 195, oil about the same, outside air temps were ~80 degrees laptimes were good.
Day two - air temp ~90 degrees, EGTs +50 degrees no read on water/oil (I wasn&#39;t driving- it was pulling teeth to get him to look at the EGTs.)- jetted up 5p/10s increased fuel pressure 1/4 pound- water ran 200, oil similar (is normal for the car), EGTs back to normal. laptimes inconsequential.
Day three - air temp 100 degrees, EGTs +100 from normal, water 210, oil 210, this was run without the stock clutch fan I normally run (I&#39;m weird)- lap times inconclusive, as I was learing the track. Jetted up 10p/10s, EGTs back in line, water temps stayed between 195 and 210 the rest of the weekend, oil similar, with and without the fan.
Its all wholly inconclusive, based on the data I have. To top it off, its only going to be in the 70&#39;s this weekend, and a chance of rain Sunday.

B. Were your lap times impacted by these temps ?

see above, inconclusive

C. Was the air temp the only difference from the previous time at the track ? (is your air intake bringing in engine bay air or outside outside engine bay air ?)

good question, the only other change was the addition of a screen covering my bumper moutned air inlet, however that was in place all three days, and would serve to restrict airflow, causing a richened concditon and lower EGTs, I&#39;d think.

D. What did your plugs look like ?

Good and black; pretty normal for a pro7.... I did change plugs this past weekend, as the others had 6 hours on them. The car felt good and strong... but, was post the rejetting to get my EGTs right.

The high temp situation has never been an issue for me. We have temps fron 50* in the spring & fall to 100* with high humidity in summer. If this high temp issue bit me in the ass & my lap times were ok or not ok I would try some cooler plugs. When Kart racing the hot/cold plugs make an enormous difference with no carb changes. But at the same time I would adjust the Kart carb full throttle needle valve while racing. Lean out of corners & fat going into corners.

Dave Lemon recommended a single plug and not varying from it, but he said the same thing about jetting.

Thoughts from others who have tried cooler plugs under same conditions as Marcus has ?

My .02 worth...

IF YOU ARE A SERIOUS 1ST GEN RACER I BELIEVE YOU SHOULD MAKE A NOTE OF THIS COMPANY...

Tom & Betty Dragoun - http://www.sevensonly.com/

I know this will sound like an advertisement but please know that I have no relationship with this company other than being a VERY satisfied customer.

Sevens Only is a full service race shop specializing in Mazda race cars. They are located at Buttonwillow Race Park in California. Everything I have purchased from them has arrived very well packaged and shipping costs are no more than anywhere else.

I own an &#39;83 ITA/7 RX7 which is raced (not often enough due to time constraints) in SCCA MIDIV (car #33). After I purchased the car I needed a carb rebuild. Couldn&#39;t get YAW to return my calls and after some serious looking I stumbled across Sevens Only. They promised a rebuilt carb that would be as good or better than YAW&#39;s and I&#39;m convinced they did it (in about three weeks). They also sold me many jets for less than $10 per set, and spent an incredible amount of time on the phone with me getting it perfect (including ESPECIALLY race weekends). They are ALWAYS friendly and professional. Tom is a wealth of info about 1st Gens and if he isn&#39;t available he has staff in the shop who have been very able to answer any question I might have.



Re EGT&#39;s...

If your EGT gauge pegs at 1700, then you may not be getting a correct max temp reading. You need to spend the money (about $300 or less for two) and buy digital readout gauges. Your motor is worth it. Mine are Sigtronics EGT-101 which I of course purchase from Sevens Only. The price included much helpful phone assistance in getting them installed correctly and instructing me about how to adjust jets based on readings.

FINALLY, I&#39;m attempting to attach a photo of my car (yellow/blue #33). If it does not post properly please forgive me. I&#39;m unsure of how this works.

I love Tom and Bette! (Okay, Eric too....)
My ITA car is at Tom&#39;s shop getting a cage... and actually, here some of the crew with it, getting it started to move it into the shop and work on the cage:

If you look closely at my BRP event pics, you will see Tom in many of them.
