since this is brought up i though i would ask a question i was thinking of today. is what the motor can take based on HP? or stress on the motor? it seems with a turbo youre stressing the motor less so its "safer". So you ran 10psi with a paxton would it be safe to run 10psi with a turbo? or is it based on HP. so with a turbo you might only do 8 psi to hit 600whp.
Part Power adder, part Tune.
With a turbo, your 8psi is gonna make more power than 600rwhp (the half decent turbo setups are). But, you are right, the blower cars need to make more power, cause they rob you of power.
The tune has a lot to do with it as well.
so is a turbo on 10 psi just as safe as a paxton or vortech on 10psi?
Id be skerd to run 10psi on my car...it would make too much power!
10psi would equal what... 850-860?
I tend to agree with this. People dont realize how much stress 500 extra RPM puts on a set of rods. That's why I will be limiting my shift points to 7000 with my new setup vs the 7450 that they were seeing before. I think E85 also helps with the tight ring gap since it burns cooler while obviously keeping detonation at bay.IMHO and open for debate -
For rods, I think RPM is the primary factor, since they see an near instantaneous direction change at top and bottom of the stroke. I don't think sheer boost and HP bends or breaks rods but detonation can hurt them.
I think ring butting is what causes the breakage of the upper ring land in pistons, not so much that the piston was too weak for the power level or not.
As for cylinder walls, whether it's a design change or some sort of sideloading, the jury is still out for me. I suppose it could be detonation, since the pressure "hammer" would be going in all directions, not just up or down.
