Im having a compression test done in a couple of weeks and I was wondering if you guys could list what are good numbers to have (with the stock pistons) for:



- N/A

- Nitrous

- Turbo



Or is it all the same no matter how your engine is built with a stock block?

 

if your numbers are 190+ and a leak down test turns out good, you are in pretty good shape..

 

+1 and regardless of turbo/nitrous/NA. I'd go as far as saying 180+ is acceptable but it will be a bit down on power.
