Okay I've installed a lot of stereo, I've installed the APS turbos, and I've added after market TC. My next "speed" mod should be...

 

APS TT isn't fast enough?

 

There is never enough speed...

I went from 5.5 0-60 to 4.7ish... I need to get 4.0 to beat my friends Z06. So taller gears, maybe cats, maybe plenumum, something... I have to get FASTERRRR.

(I need better traction... That is for sure! I cap out @ .77G, he can hit .88G)

 

traction is a big issue on this car, get some drag radials if you want traction. That's really about the only way on a TT setup

 

Clutch/Flywheel, Cams, Radiator/oil cooler....


Hmm depends on what you've got and what you're aiming for.

If you're wanting to run the 1/4 then some new rubber sounds like a good idea.

 

Aftermarket LSD.

Drag radials, then a clutch/flywheel, Radiator, LSD

 

Has anyone proven or know for sure that the stock LSD needs to be improved. How would one tell

 

Can't answer that, but in this case I believe spdkils has a base model without LSD.

 

You are correct sir... No LSD here...

Well thats not true... I have a Quaife I use as a paperweight until Quaife can get the "spacer" figured out. (Another month out for that yeah?)

I started to look at wheels, then I found more information about back pressure causing the turbos to pitter out of boost @ higher RPMs, so I started to look for cat back systems.

Then I thought about getting it tuned... but I need to have my exhaust done before that...

So @ this point I'm going to drive it for another week until my favorite shops dyno is back online. Once I know my A/F and have more information about the Quaife I'll make a more informed choice. (Lean it out by reducing back pressure? Just do the Quaife? Get a tune with my current exhaust system?)


Anyway back to LSDs, I read an artcle once that stated how much they helped. I thought it was only 20% or something like that... (Then again .77G to .92G would be a lot of traction!)
