Exactly... PSI of boost is quite simply how much the compressor need to compress the air to provide X amount of CFM at Y amount of temp with Z amount of ambient pressure and of course at XX shaft speed. Like I said...variables galore.

 

basically the better the design and the bigger the turbo the more HP you can get from it but it takes longer to spool.

in the case of greddy vs TN.. the 2 greddy are 18g turbos. which are not small by all means.. just not as big as the TN 60-1. but with 2 of them you end up with more flow.

 

Still more airflow...but less of an INCREASE in mass air for each PSI increase in pressure. And yes..hotter air temps.

 

howly psi batman............the more i follow(more like lurking) on this subject, the more technical it becomes, like this thread.........and my conclusion.....90% sure i'm going with a s/t setup(tbd: aps or t/n).....t/n kit out of the box and w/out much fuss will deliver 360-380rwhp, plug and play......aps very similiar i believe......don't mean to hi-jack thread, but buy exisitence of this thread, i'm leaning towards s/t......less piping, plumbing and less of something coming loose.....am i making sense or talking out of my tailpipe?

 

In all honesty the decision is yours to make. Suffice to say that on a stock motor you will not be disappointed no matter what you choose.

 

cool.......and thanks for your pm as well.........

 

I agree, the info in this thread I have not been able to find elsewhere...and until that damn book gets here...it should serve to provide valuable info for more lurkers to come
