| take 1 custom mapped 996sps say 120hp with pipes. Add the long stroke crank wich is an extra 28cc wich allmost gives 1 extra point of compression as well. the result after remapping is 5-6hp through the range. its a lot of work for little gain spend money on pistons,porting,pipes and crank balancing for best results |
