Turbo boost is more better?

ok i don't get it i've always thought that high boost brings high HP #'s found this article, sorry it is long. this guy put down 600HP @ 6psi ?? :read: http://turbomustangs.com/techarticles/bigjay/boost.php

well boost is only a measure of backpressure so if you had a big displacement motor with some sick flowing heads and intake then you wouldnt need much boost to make big power...

Exactly, if the heads flowed well enough to increase air velocity without totally restricting good airflow than there would be an increse in air velocity wich yeild higher torque numbers. A good form of intercooling helps also in making a dense air mixture that packs the cylinders. Since we all know that hp is a function of torque X rpm naturally higher torque numbers produce higher hp. A well flowing engine does not need gobs of boost to make great hp.

if you want more power...raise the boost accordingly...its not that hard of a concept really, some motors/turbo systems are more efficent and make more hp on less boost, its all in the set-up ;-)

Two things to consider about boost are; 1) boost pressure and 2) charge temp

Higher boost pressure increases power by increasing Oxygen density in the chambers

Creating boost take power and the higher pressure air will have a higher temperature. The elevated temp lower density and lower allowable spark advance.

6 PSI at 70 degrees make more power than 6 PSI at 100 derees. Intercooled boost is better than non-intercooled, but the motor does not know how the pressure got there.
