How much power do engine mods yield?

Yes, we will be back with a new sheet metal intake and a flat hood. With the new intake I think I have a lot left at 15 psi (better air distribution). It has been a very busy year and the race car has been on the back burner, but we are getting back on track this fall (I hope).

Will,

I still can't get over the fact that you are making all that (considerble) power with ONLY 15 pounds of boost!

I only have a carburetor on my motor; fuel injection is a little out of my "frame of referencce".... I'll probably never have the smarts to try anything but a Holley 4bbl. But, you are obviously on the right track! I have been told (by sources whose opinion, I respect, highly,) that the long-runner Aussiespeed intake manifold I m using is killing my motor. I bought it before they had a short-runner for sale, and can't seem to work up the enthusiasm necessary for spending another $500+ for the short one... What do you think?

Please keep us informed about your progress. There's nothing in this whole country, anything like your car!:cheers:
