Not trying to pick on you Jeff, but what about the clause in the new ITAC Ops manual that talks about "a minimum of 5 unique cars, somewhere in the country" being needed to warrant a PCA? Does that go out the window if the car has a major deviation during the classification process? If so, I think you would need some pretty compelling evidence. From what I can tell, you've got conflicting evidence at best. When I googled 85 Audi GT Specs, I got
this as the first link. Shows 110hp @ 5500 rpm and 122 lb-ft @ 2500 rpm. That's for the 2.2L (2144cc) motor. Same specs for the 2226cc motor. The 2.3L motor (2309cc) shows 130hp @ 5600 and 140 lb-ft @ 4000. But the compression on the 2.3 is 10:1 vs 8.5:1 for the 2 different 2.2L versions.
Unless there's some pretty solid documentation to the contrary, I think you've got to go w/ factory published hp numbers, and adjust the car w/ a PCA if it's warranted. To me,
that is the way the process should work, and is what PCA's are designed to address.
And since we're talking about VW/Audi products getting the short end of the stick, I guess I'll trot out the Rabbit GTI once more. Factory specs, 90hp, 100lb-ft.
90*1.25*17*.98 = 1874.25 (1875 rounded).
Current spec weight is 2080#
2080/.98/17/90 = 1.387 power factor or that it makes just shy of 125hp at the crank (124.8xx).
I have been playing w/ these cars for over 25 years, and I can tell you, with 110% certainty, that it is unpossible to get 125hp out of that motor w/ a
legal IT build. Call Shine, Bertils, Techtonics, and BSI and they'll back that up. I know everybody talks about what a performance choke the stock intake manifold is, and it really is. All the tuning books from back in the day would say don't bother changing the cam or the throttle body if you didn't change the stock manifold. Heck, even going w/ a stock Rabbit (non-GTI) manifold was a significant improvement. But the point is, w/o changing the cam and the throttle body, you're not going to get close to 125hp. Half a point of compression, the best header in the world, and all the balancing and blueprinting isn't going to do it. It just doesn't move enough air. If you want another reference, talk to Walt Puckett, he's down your way. The Pucketts built some of the best race headers for VW motors going.
Oddly enough, given the current process, it would land right in ITC at it's current ITB weight (actually a tick heavy).
90*1.25*18.84=2040.75
This car got boned because one guy, who should have kept his mouth shut, made an unsubstantiated claim, that got further exaggerated.
