How much HP and Torque?
How much HP and Torque? All my mods are in my sig. I had some AFR 205's installed. They're milled to 63 cc and we used .040 Cometic gaskets. The heads that were on there were Patriot stage 2 heads, which were a mis match for the cam that I'm running. How much hp and torque do you think I will gain from going to the AFR's. The previous dyno with the Patriot heads was 380 hp and 370 torque.
Not sure this is the right forum for your question - unless you mean how much will you gain after a tune. If that's the case, the results will vary based on how close your tune was to begin with.
The car was tuned after the cam and Patriots were installed. But the Tech used stock LS6 head gaskets which are much thicker than the .040's that are in there right now. Plus the bore size on those LS6 gaskets is bigger than the bore of my LS1, so I was loosing power there too. I'm guessing my compression was 10:1-10.4:1 give or take. The AFR's are milled to 63 cc, and I'm using an .040 gasket with the correct bore in it. So I'm guessing my compression should be around 10.8:1-11:1? So based on the before tune of 380/370, how much of a gain after I get it tuned can I expect?
