compression ratio on big street motor?

Cam duration and timing will affect how high you can go, too. Cams with greater duration will tolerate higher static CR; likewise, retarding the cam closes the intake valve later during the compression stroke, bleeding off volume (especially at low RPM where detonation has more time to outpace the expanding flame-front). I understand that higher compression in air cooled VW's is touchy because of heat considerations. I'm presently doing a somewhat mild performance build on a 1600 for (mostly) street use, and I am wondering just how high I can go with the static compression ratio? And how to acheive it? I have read that some builders leave the rings out between . This 1969 Volkswagen Beetle was just 0 when Steve Dalton bought it in high school.

I tend to side with conservatism. After reading some of what Gene Berg and some other respected VW folks had to say about it over the years, I came to the conclusion that MY magic number for this engine would be between 7.0:1 to 7.25:1.

# Long duration camshafts can support higher compression ratios, and in many cases run better with a higher compression ratio. If you are using race fuel, you can go higher still. # On the other hand short duration camshafts with little or no overlap can create extreme static cylinder pressures in engines with high compression ratios.

These numbers were obtained from a compression test. The maximum psi difference between the highest and lowest reading should be 28 psi. _____ 1977 Sage Green Deluxe Campmobile - "Turtel" (1978 2L FI, Pertronix, Hydraulic Lifters) . especially air cooled VW.

If you live at 2,000 ft elevation you would divide by about 0.94 to get the correct compression value. I live at 7300 ft so I divide by 0.8.

Lots of ways to fake a compression test just to get the numbers higher. Just ask any shady guy trying to sell a used engine. You really just want them all to be very similar across all the cylinders.
