We have been riding at 15 psi boost which is well over 300 HP without any problems at all.
I have been around motorcycle engines since Z1 Kawaski bike etc in 1975.
It doesn't matter how well built a engine is, detnonation will kill them all.
lots of talk about cast pistons or rods but so far I don't see a need to changed them out untill we go real big and find out.
I am very conservative when starting a new project and don't beleive in blowing up motors and then finding out something else is wrong like to high compression or lack of fuel etc.
I take the attitude that the smartest guy will win races and ride the longest instead of throwing thousands of $$$$$$ in parts or prototype parts.
japaneese build there engines with computers that are made for so many millions of cycles and so much hp before they even cast a single part.
What RPM, How much HP,How much torque, Weight, Fuel mileage, etc etc. Yes they even fail at certain things but do we really know how much power we can get from this engine without hurting it?
Only time will prove who know's what there doing and who is taking a guess.
I am going to say that with my years of experance in Motorcycles and my older brother who is 70 building dragsters and other go fast toys I listen, have open mind, and a way of seeing things in my head before trying it out first.
Where is the real over 400 HP 1200 motor? Will it live for a few runs on a dyno or pull down the lake?
I will build a monster with the help and support of friends with a passion to go fast.
We don't want our customers to be rats blowing up motors!
I think 20 psi boost will be quick with a very well designed and complete package.
I have seen apex's with 20 psi boost get smoked by a 12 psi boost same sled but different turbo system or setup.
Boost is not boost! Efficency and balance of every thing makes power.
