ITA 1st gen RX-7 weight for 2006 >

[ddewhurst]

:happy204: :happy204: :happy204:

For those who care the ITA 1st gen RX-7 12A will continue to be classed in ITA & the weight has been reduced from 2380 to 2280 for 2006 & beyond. :023:

Thanks ITAC members B)

What might be the route to get to a 2100# RX-7?

[lateapex911]

I have seen considerable disparity among 7s regarding the lowest possible weights.

heres what I think-

A completely stripped chassis.
stock fuel tank
light seat
removal of all items that can be legally be removed
efficient cage design
non sunroof chassis
light wheels
non oversized components, chosen for lightness as well as function. ie: coolers and rads

I think that certain chassis #s can come close to the target weight with a 180 pound driver.

Anyone know of any of those drivers?

Sure do he posts here as benracin, more commonly know as Ben Harding from MN. 170 pounds after a race after he/suite is 100% soaked with fresh water & he drinks a liter of liquid. Not sweat on the suite because the guy is so cool he don't sweat.

Ben, are ya 170 pounds dry or wet ? :o

ps: Since the guy is a tv star maybe he don&#39;t post with we commons. <_<

Weighting 150 lbs never felt so good :lol:

:bash_1_:

Likewise, weighing 240 never felt so bad.

Anyone have a number on how much an aluminum radiator will save?
Lightweight fluid hoses?
there fofes adding more protection/ stiffness to my cage.
cell is already in the car, but maybe I cna go to a smaller cell.
what&#39;s lighter than a 10 lb panasport?
Hoosier verse kumho- which is lighter? Is it worth it?
Small bearing rear end housing / axels will save a couple pounds.

For refernce, my chassis sans driver, (with floor tar still in place) weighs 2153, with stock radiator, 2nd gen cooler, panasports and hoosiers...

I took my ITA Integra apart and took all the sound deadening out as well as everything I coud find to remove legally (radio speakers in doors wiring for aftermarket stuff...non factory) and came in under weight...i also lost about 20# and to my surprise I had to bolt lead in it. tar undercarriage coatings (they burn anyways) fenderliners do weigh something and are best left out of a racecar!

I&#39;m 185 down from 202 five months ago and I&#39;d like to get to 180.

It took three changes.

1. I eat a lot of salad, so much so my ears and my two top front teeth are growing longer and my nose twitches uncontrollably at times.

2. Quit eating after you belch to make more room. Put down the fork and step away from the plate.

3. Buy a car in Sept. and spend the fall and winter fine tuning the prep. Suffer from short term memory loss, have your shop in the basement and your garage on the first floor and climb those frigging steps about 50 times a day. Your ass muscles will hurt.

2280# - kick ass, but not mine, it still hurts!

Short story on a Kart driver who showed up at the track weighing in 1991 at 209 pounds. I new this body weigh & 100 cc sit-up Kart where the total weight minimum was 340 pounds wouldn&#39;t work real well. :o The first wise comments I heard were who is the ol (OLD) man & where dose he think he&#39;s going. Much to their suprise half way through the season they figuired out that the 25 year old kid that was going fast was the son of the old man who was also going fast by mid season. Son finished 2nd & the guy they called OL man finished 3rd during our 1st year of Karting. Most times 15 to 20 100cc Sprint Karts. Second year the Ol Man had some real respect when they couldn&#39;t figure out how to out qualify the Old Man, which was now said with some respect.

Now that Fastrack is out & we&#39;ll continue in ITA at 2280 the weight reduction process has started.

The goal: To loose .41 pounds per each inch of my height. :023:

Two meals per day. Oat meal, two slices of rye toast with two cups coffee for breakfast. Meat, salad, vegies, fruit with zero deserts. Water, water & more water for second meal throught the day & with the second meal. NO soda, beer, wine or liquor. Rapid two mile walk a.m. & p.m. (two mile walk = 30 minutes) along with working out with a Nordic-Track dual motion deal that you use legs, arm, back muscles.

[zracre]

I found eating all day you lose more weight...not junk of course...small high protein meals (with a few carbs) and your body will start dropping bodyfat quicker. If you starve yourself your body will store fat and burn off muscle.

[dickita15]

has anyone played with a different front swaybar set up that would be lighter. I started with the 1 1/8" and then changed to the susko design modified stock bar which was 6 pounds lighter. has anyone tried anything else

[ddewhurst]

Dick, can you say hollow with alum arms ? ;)

[ddewhurst]

Evan, I been eating two meals only for the last 5 years. The breakfast is my normal. What I&#39;m leaviong out is bread, buns, potatos, cheese, peanuts, desertS, a bit of beer & wind. & the continious trips to the cupboard in the evening. :unsure: The walks a.m., p.m are normal from April through October with just a mid-day walk during the cold months. Starting today I added the second walk & the Nordic-track. Hey, they gave us 100 pounds & now I&#39;m going to ues it, emm, I mean loose it from me & the car. :023:

[kbailey]

Bravo Tom! Thanks for the laugh.

Serious questions-

Does anyone know how much the undercoating under the car weighs? The stuff inside was easy thanks to good old dry ice...but the underside looks like it would be a lot harder to remove.

How about 22 years of paint jobs? Like three extra coats? I can&#39;t imagine it will be worth stripping all the way down before I paint it, but figured I&#39;d ask.

Thanks

Kevin

I *DO* care, and I&#39;m very happy about this :happy204: - but where has this information been published???

[lateapex911]

The February Fastrack addendum.

Not only that, but the CRX, the Teg, the Maita, and the 240SX have all GAINED weight. So the delta is over 200 pounds in certain cases.

Don&#39;t expect to win the ARRCs in ITA, but it&#39;s better than nothing.

David you have motivated to continue thinking about changing my diet, exercising and drinking less beer. :023:

I must of lost a quarter pound thinking about it. Back to my beer :lol:

[zracre]

Well, you gained 115 on paper....but in real life, guys like Serra and his pals all ran 50 plus pounds heavy. or more. SO it&#39;s not going to hurt the Tegs THAT much.

And the CRXs gained a bunch as well...but now I hear power numbers 20 higher than when we adjusted it.

Hmmmmmmmm

[benracin]

See, all you guys are too tall. Loose some inches that way and you&#39;ll be better off. I&#39;m a towering 5&#39; 5" and come in at 140. Sorry I can&#39;t back up your numbers David.

And speaking of TV star, my first Hometime episode will be on this weekend! Check with a TV search deal like yahoo&#39;s tv listings or tv guide cause air times will vary. The show is called Hometime and the episode is called Townhome remodel retrofit or something like that. I&#39;ve seen airtimes from saturday till monday so it could be anywhere!

I don&#39;t know what I&#39;m more happy about. Us loosing weight, or those other guys gaining it! :happy204:

Ben, ya are just a little munch-kin, I knew yer small but dam 140 pounds. John, more beer over the off mounths for the little guy. Never worry about the competition who drive other make/models. He, He, Heeee :P

Jake, ya like the size of little Ben. Did you folks within the ITAC use the standard 180 pound driver or did ya pay some attention to the little folks ? Being that from what I read few drivers are at the 180 pound standard therefore little Ben comes out of the box at a minimum of 40 pounds ahead. ;)

Don&#39;t you know that muscle weighs more than fat? Stop all that excercising :018:

[dyoungre]

As they say, "BUMP". Now that I&#39;ve found that dieting is harder than I though, the 6 lbs I lost are not getting me close to the minimum weight.

What sort of success have people had getting 1st gens close to 2280 with driver?

My 84 is about 2295 with a full 15 gallon cell and NO DRIVER. So I figure it is currently at 2200 without fuel. My cage is over-spec (1.50x.120) and I do have a fire system.

There are a few things I can still do legally such as gut the doors (I have power windows) lighter exhaust, lighter wheels and lighter front sway bar. And my battery is actually oversize by a few pounds. I&#39;m guessing those changes could be worth 30-40 lbs. (and are about $50/lb of weight reduction). Of course I have some bondo, extra layers of paint and undercoating that could go. I&#39;d be surprised if that netted any more than 15 lbs though. (The sound deadening stuff inside the car was lot thicker and assumedly heavier than the undercoating).

Given I&#39;m about 180 with my gear on I should be able to get within 50 lbs of weight legally.

For now my money will be going to track time, not weight reduction. The driver is the #1 component I need to improve in order to go faster.

[tom_sprecher]

Kevin, gut your doors! I did my passenger door before driver&#39;s school and recorded all weights involved. After removing the window, powered regulator, aluminum cover, sound deadening and added the NASCAR bar back in I saved 17#! You&#39;re looking at almost double that.

The sound deadening in a 1st gen weights 20# and I should know since I just got done scraping that crap off and I saved and weighed it. Don&#39;t forget in the wiper cowl.

Where else you can save weight? Well... I dunno. ;)
