I knew this would happen. Got to thinking well, why not? It might mean I don't have it ready for MRLS April 10-11 but that's OK. So instead of the mostly stock head with modest BP5A intake cam we are doing this:
Integral R1 race cams, .458 lift, 283°
+1mm Supertech valves
Supertech valve springs with Ti retainers
Mazda Comp Shim under Bucket lifters
I think this motor will make an honest 190whp on race gas, without the Rotrex. Should be easily capable of 325whp force fed. Perfect for enduros where we can simply short shift to control boost / fuel consumption, tire wear and general wear. Can't wait to hear this thing.
