WHat is the optimum compression range for the wood 555 cams for twincam?

 

I was told 10.25:1

 

You can bring it up to 10.5 to get you in the neighborhood of 202 psi ccp If you want to push it that far. But yea 10.0-10.2 would be more user friendly @ 193 psi ccp..

 

10.35-10.4 is where we set those.
0 deck, .030" squish.

Thank you gentlemen

 

The TW-555 works with stock to 10.5 compression, however in most applications this cam is optimized in the 10.25 range. As Scott noted getting the deck close to zero and using the correct head gasket are important as well. There are many charts with this cam at various comp ratios and engine sizes on our dyno charts page http://www.fuelmotousa.com/p-33193-dyno-charts.html
