air in, air out

After the engine & head mods a 21 lb pully gives a max 17 lb pressure.

Ed, it is really unfair that you live so close in proximity to Shadowman ....

then again, if I did, I would be broke.

We broke the 900 barier and ran out of fuel before we could finish tuning. This was just after we replaced the old Accufab body with the new single blade on the back of the 4.0 Whipple . An initial increase of about 30 hp is what we have come up with so far. This is in conjunction with the other 16 changes we have done so far, some more significant than others. We believe that we can achieve 1000 RWHP with out going into the engine. And the adventure continues! :cheers

sweet!!! who needs turbo's to join the 200 mph club when you got a 4.0 L whipple supercharger :lol

what kind of headers and exhaust are your running and have you modified your air box in anyway?

i assume you have no cats either?

Here is the lattest number as of Saturday the 15th 925.76 RWHP and 899.32 torque
Believe it or not I am running stock exhaust, catiletic converters and a cat back pipe. The converters are not gutted but we have done some modifications to the exhaust systom. Headers are not allway's the answer. My stock air box is modified. Go to my profile and see the pictures.
