Ok guys I'm thinking of building my new engine with stock pi heads, iron block, may do cams if I can fine a deal on some use ones. Ill use ford svt cobra rods, factory 2v crank and mahle flat top pistons. The compression should be 12:9:1 the svo on 9-10lbs. It will only run on e85 and ill spray it a 50 or 75 shot at the track. I don't know if anyone else has ran high compression with low boost and nitrous on tccoa. I don't want to pulley the svo anymore. I know I can but I think the compression bump would be sweet. Hope fully I can still get 22-24* of max timing with e85. Robertp and I have never built a high compression engine before. What do you guys know about high compression and boost? It also has AIS water/meth.
