I was told not to overspin it cause of a few issues, heat soak being one!
And I always used 700-720whp as a pretty much max for a LSA stock internals!
But as I seen some of your work I'm not doubting you at all
!! So I'm pushing 661whp now at about 13 psi! With the works done except porting the blower!
As I was wondering in the range of a 850whp monster which this blower/motor can't handle stock but the crank is super strong, rods and pistons need to be forged! But seems everyone just says " well reached stock LSA limit lets slap 427, or RHS 4**!
Keep the madness coming btw!!
