ITR
1. #2501 (Tristan Smith) Please re-examine weight for ITR 300zx
In 9.1.3, ITR, Nissan 300ZX (89-96), change the weight from 3250 to 3120. [An error was made during the initial weight-assignment process.]

Thanks ITAC

[23racer]

I just wanted to say thank you to the people from the SCCA for clearly stating what I need to do to be able to run with you guys next year;

#3415 (Eric Nummelin) Classify 2002 Cougar Using WC VTS
The car is eligible for STU with the appropriate STU specifications and by bringing the compression ratio in compliance.

While I do find it a bit confusing that the car was still legal to run in World Challenge in 2010 and in STU as well, but the new direction of the class is to not allow that. Greg Amy did a very good job in keeping me informed as to the process and I want to thank him. While I am disappointed that I have to put my spare motor in the car and loose about 40 hp and make the car a ton heavier, I have nothing I can really complain about, rules is rules. I just need to change the bullet for a more stock one and bolt on about 150 lbs of weight, . With these changes I can expect to have my a$$ handed to me in the races, but I get to keep the car mostly in its original condition.

I just wanted to come down and run the car in a couple of races a year for kicks and giggles and I understand that the actual SCCA membership needs to understand and determine the direction the STU class proceeds in and not change for 1 car.

All I have to do now is work out the licensing issues, pick a region and see what weekends work the best for me. Thanks to the CRB for clearing up the questions very quickly and I while I wish that I could run to the WC VTS approved in 2009, it doesn't meet the direction of the class. I will need to think about things a bit to see if it all makes sense.

WOW!!!

#3394 (Josh Sirota) Reevaluate weight/class of ITB Dodge Daytona
In 9.1.3, ITB, Dodge Daytona 2.2 (84-89), reclassify from ITB to ITC at 2380 lbs. and classify the identical Chrysler Laser, effective 1/1/12. [Note separate Technical Bulletin item to reduce 2011 ITB weight to future ITC weight.]

no mk1 MR2... figures.

[JeffYoung]

Steve, I understand the frustration. All I can tell you now is that we spent a lot of time discussing the car, and the data you and others provided.

I personally am in the camp of re running the weight at 25%. That's probably the best you are going to see. While I agree the evidence suggests (pretty strongly to me) that even 20% is tough for these motors, the fact is we don't have a full on IT build to evaluate.

In any event, the issue is still open. I (again personally) hope we get this done next meeting. We'll see.

They dyno I gave you what made 108whp is a full tilt buggie motor that was built by TED componets. My motor, has every possible thing done to it that I could find, sans a header built on a dyno and made 106.75, others are in teh 103 to 104 range on a dyno that is not ego-inflated. All those numbers are below 15%, let alone 20 or 25%. Even the few inflated dyno's that you can find (though teh majority shows I am right) are below 20%. Stock rebuild dynos are around 97hp. I mean the cars are so un-competitive it is rediculous. How much more time and money do I need to invest in my car before someone looks?

I am not going to make a mod list, but you name it it has it. Custom made struts housing DA konis, Bearing LCA's, custom header, intake tube, spent hours on the dyno, custom rings, and alot more setting and testing the suspension than actually racing this year. light wheels, sticky tires, aero data, tuned exhaust, tested brake pads, etc. what more?

What more information does the ITAC need? Seriously? 100lbs or 200lbs isn't going to make it a "class killer". we would have to make something like 125-130 something hp to the wheels at the current weight.

This is just like this year at sebring, when a guy came up with no knoledge on MR2 and told me my motor should be making 130hp. I told him more than he cared to hear, but no mater how much facts I told him he said "well your missing something", and I watched him balk up in the corners then mutilate me in the straights. I talked to a few others and their solutions were cheating. I am not going to do that. I would change class before that.

At roebling I got lucky and snuck into the lead after the leaders had an issue on lap 1. I had a 3 car length lead coming out of 9. By turn 1 I was a car or so behind them. same class.

[JeffYoung]

I did the initial analysis on those cars. They are tough birds. No power (same motor as Omnis, etc.) and too much curb weight. I owned one of these turds back in the day (an 84 Laser).

In B, they'd have to lose something like 600 lbs off of curb to get to process weight. In C, they still probably can't make the weight but at least they have something of a chance....

WOW!!!

In case it's a little confusing: the Operations Manual for the CRB states that reclassifications are not like weight adjustments -- reclassifications need to go through the rule-change process. That process involves a member input period, and the proposal is subsequently voted on by the BOD. Now that there is a "rules season", rule changes and reclassifications are "closed" for 2011, they will be voted on for 2012. So the ITAC/CRB is reducing the weight for 2011, which we can do now, and have submitted a request to reclass for 2012. I suspect there will be other examples like this as we work through our list.

WOW!!! is right!! There is a Santa Claus!! Looking at this as objectively as I can, I think this is fair. The car would never make process weight in ITB, and ITC needs more cars. As the car is now, I've been racing with the slower ITC cars anyway (and having a good time). Now I need to find 250 lbs to take out of the car...

#05 ITB (for now) Dodge Daytona

[JeffYoung]

Bob, I did the analysis on the 2.2 Mopars and I'm glad you agree. I really should have asked you if you wanted your car in ITC before I recommended the move to the committee, but I frankly didn't see any other option. THat car has NO chance of making weight in ITB, not even close. It was something like 600 lbs over versus Process weight.

Let me know how it goes. I had an 84 Laser back in the day, and kinda sorta know what you are up against...lol.....

In 9.1.3, ITR, Nissan 300ZX (89-96), change the weight from 3250 to 3120. [An error was made during the initial weight-assignment process.]

So what was the error? As I recall it was classed with an assumed gain of 30%, was that dropped to 25?

[JoshS]

Correct. This was the only V6 in ITR done at 30%.

[JeffYoung]

Not knocking Johs, but I think the actual thinking was that basically ALL sixes in ITR were hit with a 30% gain (at least) whether there evidence to support it (like with the BMW 2.5 motors) or not (the Supra and the 300ZX).

In my personal opinion, the Supra should get a similar reduction, if requested.

The SHO, Acura Legend, Stealth, Contour SVT, 3000GT, various Porsches were processed at 25% IIRC.

[JeffYoung]

You are right on the SHO, Legend, Stealth twins and Contour.

I think the Porsches got less than 25%.

The Toyota and BMW inline sixes got 30% -- no data at all on the Toyotas. So too did the 300zx.

I still don't see any evidence being available on that motor. To me, builder speculation prior to a build doesn't cut it. Real data does.

Thanks on the last statement. It is appreciated. It was true when you led the ITAC and I hope we try hard to live up to that standard.
