09 CTS-V vs. 03 Whipple Cobra
#23
I'd bet that Cobra I raced is a good 500-600lbs lighter.

My only/uneducated guess is that the ZL1's heat faster and the tune pulls timing quicker/at lower temps. I'd assume the V hooks better too, but thats only a guess.
I see no reason why an auto ZL1 shouldn't run with a V, mod for mod. Pretty sure they are almost identical in the 1/4, stock. 11.9-12.1 seems to be where most of the good runs are for both cars (stock), no?
There are some V's in the 9's on stock blowers + spray and 1 or 2 in the 9's with bigger blowers and no spray. I'd like to think the ZL1 can do the same.

Most guys are using stock converters and simply leaving off idle or loading to ~1000-1200rpm and cutting 1.5's. Local guy (who helped convince me to buy the V) cut a 1.69 his 1st time out, while on 20" nitto 555's, lol.

I'm partial to the GT500, I just like Mustangs more.
But, it's easy to see that Ford released the GT500 spinning that TVS almost to max, right from the factory. If I'm not mistaken (I very well may be), 15PSI is getting pretty close to max efficiency out of that TVS2300. Spin the ZL1's blower faster (easy fix) and it's more of the car it should have been, imo.
Oh, GM should of also manned up and put the damn 2.3L on the LSA.
