Title: Effective Compression Ratio for Boosted Engines
Post by: VWRacer on May 02, 2005, 07:14:44 pm

Hey guys!

I was cruising around looking at interesting motorports websites and came across this page: Compression Ratio, with Boost, Analysis (http://www.teknett.com/pwp/drmayf/comprato.htm)

So I thought I'd plug in the numbers for my TD and see what I get. :twisted:

Effective CRboosted = ((Boost Pressure / Atmospheric Pressure) + 1) x Mechanical CR.

((10/14.7) + 1) x 23 = 38:1  :shock:

Try that in your gasser! :lol:

PS - Click on the guy's home page link for lots more interesting articles. I think I'm going to save his whole website to my HD.  :idea:
