The 390hp is thru a 4000stall and a 12bolt, its really not that nasty of a setup. The car just gets outta the hole nicely

I dont think there was much of a difference with the new headers NA, i dynoed in way better conditions last time, but i believe they helped on the juice

I'm at 11.5/118, maybe 11.3 at 120
how do I lose 3 more tenths at the same mph - weight?
tire spin perhaps?

nice results

The car sounds sick and works well. I'm sure you will get your 9 sec pass at those power levels.

good luck

Awesome stuff. My old 355 combo in the sig put down very similar numbers within 10rwhp of both NA and the 150 shot of yours. Stalls kill dyno hp. You must have a raceweight under 3250lb to cut those 60ft's NA and run into the 10's with 3.73 gears.

Congrats and 9's should be easy.

Yes they do ...but ET/MPH is the real determining factor with cars like this

The car has a #3400 raceweight.

But why post all the mods done to your car , put it on the dyno , claim it runs 10.9 and 10.3 on NOS... which i totally believe but you wont post HP an TQ numbers

Are you trying to tease us come on... you can even pm me i wont tell anyone
