>I really like my T-trim and have absolutely no problems with it and I have a FMIC from PTK http://forcedinductions.com/GMkits2.htm its an air to water.

 

Just keep in mind that if you go that 383 route, you'll be looking to toss that S-trim pretty quick. I think it would be hard making 20psi on the S without overspinning the daylights out of it, especially on a more efficent 383 setup.

its completely pointless to overspin a blower though isn't it? I mean spinning them past their rated rpms. Like the P1SC unit's max is 62,000rpm.. so going to say 65,000 would produce less power then staying at or under 62,000rpm correct? or is it a diminishing returns type thing?

 

What Does FMIC mean? some kind of aftercooler?

 

>FMIC = front mount intercooler

 

Exactly my point of why he'll want to toss the S-trim on a 383 setup. And your right, no gains in overspinning it except to run it further past its efficency range and make less power. It's interesting to compare the max efficency numbers on the S vs the T and see where there gonna make their most power at. The T seems to be a nice fit for a 383 setup. A Ysi on the other hand seems like it wouldn't even have to work hard to make good power.

Yea, kinda the same thing with the F1 Procharger model. Unless your aiming for 1,000rwhp the F1 doesn't even need to really work hard.

Now as for my P1SC, i'll be working the hell out of it

 

Wow that was a good deal. I sold just my P1SC head unit, tensioner and 4.25 blower pulley for $1725.
