My main thing was to try to NOT run an intercooler.
Every intercooler that I have seen...out of the box looks like a rigged set up. I think I have only seen two that looked sweet, because they spent the extra time and money to make it look good. No bashing here, but intercoolers...aftermarket are just uggly.
By raising the compression you do not over work the M90, causing extra heat wearing out your fluid in your blower and so on. M90's that are running like a 2" pulley is just sick man. They can handle it...but just wasnt really designed to be ran XX,XXX RPM's.
Ya, high KR and a chance of preignition is what those high RPM blower spinners are looking at with no scanning done. They have to spend an additional $1,000.000 odd some dollars in supporting mods, intercooler...machined snouts...additional scaners and what not. Lot more work than its worth. But if your not tearing apart a motor...and just plan on adding mod after mod after mod...spend more to get about the same gains in my opinion.
In building my engine...this was more cost efficent to me.
My second idea I had for a build was to lower the compression, and run a Animul/Whipple set up. But the idea of setting some good times at the track and good numbers on the DYNO....most everyone would say "it just because you added a different blower". I think the M90 isnt a bad blower...untill you start the additional spinning. But it does sound cool.
