with the mafpro dont you have to have an impedance converter to run bigger low impedance injectors.
now if Harlan could include that in the package at a resonable price id be sold.
but i guess my megasquirt will have to do.

i'm running 60lb injectors so the stock PCM is fine with that, no need for larger ones with my power goals.

you will definately do it, im sure of it.

on another note, do you have any video clips or sound clips of your setup? I was curious how the Tial 50 mm BOV sounds, since thats what im gonna be getting.

I just have a sound clip of the WG opening....thats loud as hell. You really have to listen for the BOV...its too quiet I was used to my MONDO on my ATI set up.

I was sure of running a 10 pass too, but a crappy track and this crappy altitude were at doesn't help much. Best pass with the ATI kit was 11.10@124

hmmm, what is your suspension setup like? how are your 60 ft times?

how big is your stall? what kind of tires/wheels are you using?

im sure there is something that can help your short times a little, you definately have enough trap speed to et 10's...

Car usually 60 ft'ed in the 1.59-1.65 area with the blower.

This was on ET Drags 28x10.5x15s with skinnies up front.

Stall is a 3800 suspension is BMR track pak(-2.5 pinion angle) Air bagged right rear, no front sway bar, BMR Lower control arm relocation brackets(lower hole) BMR LCAs.

Our DA usually hovers in the 6500+ above sea level range.

Track hook is joke, Most the time prep is non existant after the launch pad. My car will hook only to spin right off the pad a second later, prep rarely goes past the 1/8 even on days that we have events with some high powered cars...wrecks are almost a nightly occurance when cars are running. Prep in the launch box is also a toss up most the time.

My car launches like a lot of the other low time guys, launch spin, wiggle all over, lift, run it through the traps.

Hopefully with the turbo the car will launch a lot softer, with the s/c it was pretty violent on the launch, now I can barely spin the street tires on an aggressive launch. I'll have to be careful because turbo cars usually eat it half track once full boost comes on, instant sideways action.

I would think even with a turbo, brake boosting it would be pretty violent too.

I just keep having that image of when harlan ran that 8.29 at 165. man that thing took off like a bat out of hell.
