The stock FI and the Holley 350 are about even as far as power goes. The little Holley5200/weber 32/36, is slower than the stock setup. WE have the baby weber on the Chumpcar, and it is slower than the stock parts. The good news is that it only revs to about 6300 and the drivers cant kill the engine at that RPM. If i get beat on power than maybe I will find the FI setup for it. It came with a carb and it runs well enough to be top three.
I have; the Chumpcar ABA 2.0, HT head, @ 11-1 comp, Weber 32/36, nice cam, about 110
[email protected] 6000, great torque, MK 3 exhaust,
ITB Golf 1.8 @ 10-1 stock intake, good VW cam , TT header, about 120hp @ 6500.
Roundy ministock with 1.8, 11-1, 268/288 cam, dual downpipe, Holley 350,
[email protected] 7000+
All run on AV gas @ 100 octane, all are gapless rings, all are 025 off the deck, all heads are angle milled...
A well setup CIS- FI will out run the Holley 350, but not the 500, esp if you have more cam. or cams. IMHO.
The compression is near 13- 1 with the 16v pistons under the 8V head. I cut off 040 off of the top of them to get it near what Av gas will run. (12-1). Cutting any more off gets thin on the crown and gets close to the top ring.
FWIW if you call Colin @ TT, and tell them that Mike @ "Protech" sent you, maybe they will cut you a deal on their cams. They are alll stock base circle . cam and springs runs about 200$
