Default accel dfi gen 7

Hi,

I am new to this forum and need some help on tuning. I have just rebuilt a 400 small block and have installed it in a 85 corvette, 30 over, 4340 scat crank and rods, speed pro hyperutenic pistons, TPIS intake, 1160 throttle body, 42 lb injectors, comp 600 lift cam and roller rockers, edelbrock heads, an acecel dfi gen 7 stand alone system, I have just purchased a wide band for it. Headers, 11 to 1 compression ratio. I have not dyno tuned it yet but I suspect it is some what north of 450 hspwer at the flywheel. The installer has done a pretty good job of installing and setting up, but I need a killer tuner who is really good with the accel gen 7. As long as he is on the west coast anywhere west of Utah. Any suggestions would be gladly received.

Thanks,

Wayne Nelson

If I was out west, I would use Tom. http://forums.corvetteforum.com/member.php?u=43150

Do a search and you will see, he is probably the most knowledgeable person on this forum.

BTW he is a Accel DFI dealer

if i were to make an educated guess i bet that makes 500 fwhp and 400 at the wheels. That is a pretty stout motor, although that is a lot of lift, whats the duration on the cam? and did you do any research on the parts together? or just bolt on whatever?

Default desk top dyno

Hi,
I used a desk top dyno, and when I put that particular cam in the profile the engine created lots of horsepower, really came alive. The duration is 245 on both. I had to replace the springs on the edelbrock heads which we shaved 60 thousands.

I have a Gen 7 in my 85 with a 408SR and had Dave tune my car and he did a great job. Or you could take it to Tom Wong and he'll get you squared away too.
