Had the new cammed now 20 lbs Whipple 93 octane "Termi" dynoed at Lidio's yesterday. Boost dropped from 23 to 20-21.
After the drivabilty issues were figured out, the first true pull made 656.1/618.1 @ 11.5 AFR 18 degrees timing
Richened it up to 11.2 AFR made 659.7/616.1 17 degrees of timing
To be really safe the timing was brought down to 16 degrees 645.5/634 and that is where she sits.
Race gas timing was set to 22 degrees (added 6), probably seeing around 680-690 (put 651 to the wheel with race gas tuned to 11.6 AFR).
So am seeing roughly the same HP/TQ with 93 pump + cams as I saw with race gas without cams with all else equal (5 degrees weather difference). The cams are worth 20-30 RWHP difference give or take a few.
Lope is bad ass, mild classical cam sound that shakes the engine and car at idle. SOB pulls like a frieght train between 2500-5500....
