I wanted to know a few things about uprading to a t-trim or maybe bigger. Right now I have a s-trim and at about 4500 rpms the boost stops climbing at 8#. A friend of mine is having the same problem. We were woundering if a t-trim fits in a s-trim bracket. Has anyone just changed for a s to a t-trim and used the sme pullley? if so what is the differance in boost? Both cars have 383's in them. I am thinking of putting a intercooler in down the road and I know that I loose boost from it to. I am tring to stay around 12# after I put the cooler on.
