Does anyone know what the compression should be on a 1992 indy 500?
Compression on a 92 indy 500
- Thread starter mt.sledder
- Start date
85 PSI at 7800
Two strokes tend to have lower compression ratios than, say your car. But I'm assuming you're wondering what kind of PSI readings to expect using a compression tester. This is altitude dependent, but for a reference I get around 85 PSI for my freshly rebuilt (but broken in) 1990 Indy 500 motor at 7800 feet above sea level. Can't say for sure, but I think 125-130 PSI is more standard near sea level.

Interesting. I didn't realize it would be that much lower at elevation. Good to know.
