New e/t's, tried the nitrous.
Ran a new best on the motor this weekend...12.41 @ 111.02. I also tried the nitrous this weekend, ending up losing the nitrous jet for the 100 shot somewhere in my pit space so I went with a 75 shot. Ran a 11.85 @ 114.03. So I am pleased with it so far, and that was with a rich 75 shot as I had a larger fuel jet in their to be conservative. I am going to try the proper 75 shot jetting next weekend, and I'm going to have a new jet for the 100 shot.

What kind of heads and cam are you running on that thing? What kind of compression... what intake/runners/etc? What kind of Pistons (hyper or forged?)
Sounds pretty nice, I'm hoping mine will run mid 12's on the motor.
What gears you got out back?
What about suspension mods etc?
I'm just curious.
Nice times tho.

My heads and cam is World Product S/R's ported and a LT4 hotcam.
My intake is a Miniram.
Pistons are Weisco Forged.
3:73 gears (Yukon's for the 9 bolt), Eibach sportlines, LCA's and brackets, panhard bar, KYB shocks and struts, Edelbrock torque arm.
Compression is about 9 3/4:1
Any others questions you have just ask.

, what kinda exh system you running? You set up it close to mine except mine is 350 but I am running WAY slow @ 13.7, think the Edlebrock headers and Y pipe are the problem. Thread Starter

Schultzy - Every race weekend for the past 4 or 5 in a row the car just gets better and better. It has been a great summer for the ol' GTA!
Hope you have has much fun when you get some stickies. Keep me posted bud!
Fevre - My exhaust is Edelbrock shorties (ceramic coated), custom made y-pipe to fit around the deep sump oil pan, no cat, into a 3" Flowmaster American Thunder exhaust. Followed up with polished tail pipes.
