alright this may be a stupid question but answer it anyway....

if you are boosting 10psi with a super charger, what is the difference if you are boosting 10 psi with a turbo setup?
Turbo will obviously have lag but will they give the same high end hp numbers? Also will they both put wear the engine just as bad?

If you are pushing in the same amount of air into the engine shouldnt you get the same results? or am i missing something?

for example lets say we are talking about a jrsc with a 10 psi pulley and a drag kit boosting 10 psi.

what do you guys think

 

It's all about CFM. I don't know what kind of numbers the JRSC flows, but if it flows less CFM than a T3/T04b/e in a DRAG kit, even if it produces the same manifold pressure of 10psi, the DRAG kit will yield more HP. The Same goes for smaller and larger turbos. A smaller turbo maxed out at 10psi and flowing less CFM will not make as much power as a larger turbo at 10psi that flows more CFM. The larger turbo moves more air at 10psi, and makes more power. Also, at 10psi, the JRSC is getting pretty close to its thermal efficiency limit, which means the air it's pushing into the engine is heated to the point where it starts becoming counter-productive to making power. As for the wear and tear, I don't really know which would be harder on the engine. Since the turbo setup would have a cooler charge, I would figure it'd be a bit easier ont he engine. The JRSC heats the intake charge just before it enters the combustion chamber, which means it's more likely to detonate, so if you're tuning isn't spot-on...

 

There's also the drag of the supercharger to consider.
