troyhyde Posted January 7, 2010 Report Share Posted January 7, 2010 I was doing some reading on this same subject. Johann (who seems to have some chops with these cars) suggested in an older post to only use the NA intake cam. I figured his suggestion was from a reliable source.

gilber33 Posted January 7, 2010 Report Share Posted January 7, 2010 By just using the intake n/a cam does that provide a more even power spread? Quote Link to comment Share on other sites More sharing options...
v4lve Posted January 7, 2010 Report Share Posted January 7, 2010 By just using the intake n/a cam does that provide a more even power spread? kind of, can make adjustments to the powerband. Advance for more low-end or retard for more high end. I'd also like to do this in the near future, to those who did both how big of an issue was overlap and what would you say your actual adjustment was?

Does that mean that you entirely loose your high end power, or it's just turned down a bit?It seems like there's a lot of unknowns with the NA cams.

Does that mean that you entirely loose your high end power, or it's just turned down a bit? It seems like there's a lot of unknowns with the NA cams. No, All it simply does is shift the power band slightly... It is known to the community that about 15hp is gained from switching to NA Cams (Yet its hard to find exactly what setup, intake only both or exhaust) Advancing and Retarding Cam timing makes a huge difference in the powerband though! So be careful how much you advance/retardand considering you can find a set of N/A for about 20$ a set at a local junkyard thats almost 1$ per HP, if only everything was that cheap!

I set the cams at the stock turbo settings, which is about 4º adv EXH 0º INT Quote Link to comment Share on other sites More sharing options...
