I beleieve that the Indy racing league use these engines so if you read up on this you will be sure to see how to make big power with these engines.
There is quite a bit of extra power to be squeezed out of them. Primarily use bigger injectors, uprated fuel pump, induction kit and a rechip. Skimming the head will increase compression. With a Large engine you really need to focus on improving the low down power as they do rev very highly. A mild fast road cam setup would help with this.
Have you thought of introducing a supercharger? |
