Alright,

I'm doing a 3.8L build-up for my 90 Firebird(I know its not a real TTA:frown: ) I'm finishing up the engine build and trying to get some ideas of what to expect in the 1/4 Mile...

So far, I've got;
87 3.8L balanced, align honed & bored .030
TRW .030 Forged Pistons
Stock Crank(.020) & Rods (All ARP Fasteners)
Stock 87 GN Heads (valve job & new springs)
208/208 Flat Tappet cam
TE-44 Precision Turbo
Siemens 55Lb Injectors
Mease 2.5" Downpipe
Kenne Bell Upper Plenum & Throttle body
Stock Intercooler(stock neck)
TH400 w/ 3000 Stall Torque converter
01 Trans AM 3.23 Limited Slip 10 bolt rear
Spohn Adjustable torque arm
275/40/17 Nitto 555r's mounted on 17"x9.5" Z06 wheels

Im just wanting it to run but, some ideas will be nice too. I think I covered all the necessities, I'm going to get an Alky Kit as well, I'm kinda hoping for at least low 12's and maybe more w/ Alky. Let me know opinions. I know I need to open up the intercooler as well as the downpipe.

I hate making predictions but low 12's should be easy if everythings right and you get traction. For example my old stock TTA went 12.50's on pumpgas and 11.90's on racegas with just a K&N filter/maf pipe, thrasher chip, dump pipe, ET Street tires on stock rims, and 18lbs of boost pumpgas/22lbs of boost racegas.

HTH,
Steve

I think you'll get low 12s. Your set-up looks like my set-up. With tuning and octane maybe 11.70s around 112 to 115 mph. Good luck with it.
