Well, after finally installing my 42# injectors and Accel DFI and ditching the FMU, i took the car in and had it tuned (318 rwhp - 345rwtq), i went to the track this morning and ran

About time you got in the 12's

What type of tire were ya using?

 

BF Goodrich drag radial @ 15 psi

I was alittle discouraged after my first run which netted me a 13.009...i thought 12's were gonna elude me again...

very nice :hail:

 

wait you made 350horsepower on 10# of boost? im lost.

 

no...i made 318 rwhp on 9#'s boost, (belt was slipping)...this was on a mustang dyno FWIW.

What's the problem???

 

Can you scan and post the dyno results. I would really like to see how your power band turned out since your car and mine have about the same mods in it and I have no access to any chassis dyno.

 

I'll see what i can do....i don't have a scanner, so it ma take a couple of days.

are mustang dynos the ones that read lower or higher than traditional chassis dynos?

Im just surprised the numbers are so low; even my dead bone stock 350 L98 with 5 PSI of boost made more horsepower than that with a roots blower and a carb. my 355 with heads/cam/intake and 5psi made nearly 420RWHP with the horrably inefficient roots blower.

I too am interested in the dyno sheet; 9 PSI is alot for any V8, especially a nearly stock one. Im impressed, dont get me wrong, but Im just confused

 

from what i am told, the mustang dyno's usually read lower than the dyno-jet's...this will be verified soon by the place that dyno'ed my car, they are in the process of hooking up their dyno-jet. so only time will tell..

as soon as i can get the prints scanned i will post them...

when the guy tuned my DFI, he tuned it very conservative (10.8 air/fuel ratio at the topend...)
