Project 88 GT update
 

Well guys/gals - update on our project 88GT stang that my son and I have been building. My son just broke into the 13s (13.5) for the first time with the car! It is so cool watching your son run the 1/4 mile.

Still working with him on his RT and 60' times to get improved. Not too shabby with street BFG TA radials and stock suspension.

Here's a list of mods to date:

CenterForce DF clutch
MAC long-tubes and hi-flow catback
underdrive pullies
Pro5.0 shifter
ZEX 75-100 shot
Kenny Brown subframes
aluminium driveshaft
3.73s
Eaton posi
31spline axles

Still stock:
stock top and bottom end
speed density

On order:
adjustable rear control arms with poly bushings

I'm wondering if he could break into high 12s with good suspension work, good tires maybe slicks, and better RT and 60' times. Any comments on whether this is possible with above setup?

Defintely is possible with some suspension work and slicks I think. By the way thats a very clean set up you guys have. Anyhow you might wanna try a Nitrous Express kit, they rate their nitrous kits at the wheels, you could try a 125 hp shot of theirs. Buy it used too off ebay or message board classifieds. Maybe even a junkyard Mass air could help. Just dont go with a cold air set up, maybe a march ram air. Just seems like you guys got all the right basic stuff, good luck!
