High 12's??
 

I currently have a LS1 GTO A4 with nothing but a diablosport tune. My question is do yall think she's capable of squeaking into the high 12's on street tires with these mods:

Kook Headers/Mid-pipes
Borla Catback
K&N Cai
Diablosport Tune

I'm hoping I can get at least into the low 13's with these mods. By next summer/fall I should have all this

Well, just an opinion here but the sixty foot times are going to be really hard with stock tires. The independent rear is kinda tricky. I've seen a LS2 GTO (fathers) run 14.0 to 14.2 over and over. It was very poor weather and we are at bout 3000ft. So if you get lucky with the weather man and get a few runs in to learn the launch, I would guess high 13s.

High 13's?? I can get that stock down here at sea level. I'm talking about in favorable conditions and with a good launch.

On street tires I dont think you will hit 12's. Throw on some dr's with those mods and you should be 12's no problem.

13.4 would be my prediction.........

There's a guy with a LS1 GTO A4 with nothing but a diablosport tune and K&N and he ran a 13.29 at 103. That gives me confidence.

if you are at sea level 12s shouldnt be a problem with traction....

Get a set of Drag Radials they knocked a half second of of my 1/4 mile times. I went from 13.3 to 12.79. Traction is the most important thing and the DR's cost much less than the catback with better gains.

Lol, they said that on ls1gto.com "get a stall, get gears, get slicks, etc....."

I'm not going to get any of those. I'm going to try to do this on street tires.
