I just looked its not on the website, although they do mention it in their exchange program. Prob a real old model of the v1.... prob old enough that they dont even bother listing it anymore?

I can vouch that the t-trim is a killer blower though. I am making 400+ rwhp with 7 lbs of boost where a v1 s-trim would need to be making at least 10-11 to make the same power (keep in mind I do have cams though)

tho two articals explain what it is, 2cnd ones better. educate yourselfs, READ!

Yeah man I was all set on going with the V3 but heard some really good things about the V1 T-Trim (plus that sound at idle is soooo sweet)..

So much misinformation here. 0949er I don't think you actually understand the difference between an S Trim and a T Trim. T Trims are able to put out more CFM if spun higher and maintain good efficiency. They have the same step up ratio and on the same pulley size will output the same CFM as an S-Trim. An S trim on 9psi will put out the same hp numbers as a T-Trim on 9psi. PSI is a measure of restriction. Meaning because you have cams for the sake of argument 400CFM only causes 7psi in your car where 400CFM in a non cam car causes 10psi.
