Which 85 Stang exceeds the performance levels of ITR?

[Flyinglizard]

The Mustang fits fine .
What about the ITB Rocco 2 with 180#s out?? Can that be right??
All I have to do is remove the cam and that car is back in class.

Why should it weigh any more than the A1 GTI? Same motor, trans, brakes, suspension, but much higher polar moment of inertia with the park bench bumpers.

That said, I think it is a great car for B, as is the A1 GTI, but no one has seriously run one after the weight was corrected.

looks like he asked for 181 #'s to be removed and it dropped 50 #'s

ITB
1. #4729 (Brooke Fairbanks) Reduce the weight of the 83-88 VW Scirocco II 8V by 181 lbs. In ITB, Volkswagen Scirocco II 8V (83-88), change weight as follows: from 2130 to 2080

My letter was submitted in April, 2011 and was as follows:
Letter #4729
Title: Reduce the weight of the 83-88 VW Scirocco II 8V by 181 lbs.
Request: The 1983-88 US version VW Scirocco II 8 valve 1.8L "JH" motor produced 90hp from the factory.

Based on the ITAC Operations Manual, version 0.9, July 2010, this model vehicle should have a minimum racing weight with driver of 1949 pounds (using an assumed 30% gain above stock in IT trim). The calculation is as follows: 90*1.30*17*.98 = 1,949.22 rounded to 1949 lbs., down 181 lbs. from the current 2,130 lbs. Please consider this change. Thank you, Brooke Fairbanks SCCA member # 418214

I used a 30% gain versus the 25% hp gain due to the "drink straw" size exhaust manifold... ...the new weight now matches the 83-84 Rabbit GTI, but that's not what I requested.

the one with the 210hp V8 with 4bbl carb sold only in 1985.

that doesn't sound like too much for R to me... what am I missing?

[ShelbyRacer]

Interesting that the CRB is "keeping my resume on file", yet I believe I've been added to the ITAC...

I'm not a ford guy, nor american muscle guy in general, but those on the committee who are presented arguments that the specific mix of components on the 85GT, combined with IT rules, shakes out beyond the intended ITR performance envelope. we therefore voted to not allow it on those grounds. given the EFI cars ARE classified, I think it works out as a wash.
