over on the turbomustang site their is alot of discusion as to how much boost you can run, or what is better higher or lower compression with less or more boost respectively. maybe you guys could post what type of head you have alum/iron, compression you have, boost you are running. maybe some input or thoughts as to an optimal setup for street or foer strip.

 

It's actually not that debatable. High compression with low boost is far more efficient.

What is debatable is which way is best to go for an individuals needs.

For certain power output levels the issue is not that of efficiency, but that of engine survival. In a lot of cases you can reach higher power outputs reliably with low compression and higher boost.

 

what exactly do you mean by "far more effiecent"? i know higher compression will make more power the higher it is for a determined amount of a/f. however, when you look at volumetric efficeincy you are looking at how much you are moving through the engine. just asking because many people feel this way too...... but math does not support it.

 

I dunno about effiecency but lower compression and higher boost makes more power.
