With that said I'm sure someone will post up an example to prove me wrong. Turbo(s) are by far the easiest way to that goal with a car that can run like a stock small block when cruised. Not ideal usually for the track stuff as they can be fun to drive fast, but they are trackable. A good electronic boost controller to control how the boost ramps up vs rpm and gear would be a great idea. I had several laps with Stielow driving the Mule, and it worked quite well; the boost was turned down a bit though, not on "kill". Then again, that's Stielow driving............ 
My ideal engine for my next car would likely be a roots blown LS. I figure it can make an honest repeatable 750-850+ HP, and that's plenty. Boost is instant, and a bit easier to drive fast I believe. |
i havent taken a roots style blower off the table. I really like my kenne bell,even though its an older version.
