I got the S-Trim impeler upgrade back from Vortech, and went to Mathews in Longmont Co, for tune, They have a Mustang dyno (only been on Dynojet befor today) After about 25 runs it looked good on paper, A/F good 392 rwhp with tq @ 321. 10 psi.
My last DynoJet before impeler and Crawford headerswas about 398hp so I didn't think too much, but road test made me think otherwise!!! Wow.. I'm happy for now.

 

Glad you're happy

 

Congrats on your numbers!!!! Are your headers heat wrapped by any chance?

 

Kevin...good to see more guys upgrading the blower . Im surprised you didnt get more boost from it . Time for the 2.87 pulley , your not even close to its max rpm rating . Are you going back to your Dynojet to compare ? Bet your in the 450whp range

ooops..edit...I miss read your post . Though it was a T-trim . You still ended up with great hp on a Mustang dyno

 

The S-trim is a nice upgrade to the V2. Isn't the Sc-trim a slightly cut down S-trim.

I think they both have the same overall output and flow, but the S-trim can do it at lower impeller speeds. Basically, you'll get more boost using the same pulley that you were using with the sc-trim.

I did the same upgrade on a V1 when I had a blown 96 cobra. It was good for 536 rwhp at only 10.5 psi (6200 rpms)

 

Ive upgraded to the T-trim blower . Working on getting up to 16psi . Was at 13.2psi , but the IC that comes with the kit is way small and to much back preasure betwwen IC and blower is to high and belt slips no matter how tight I got it

 

how does the T-trim or S-trim power curves look?

do they start looking a little exponetial or are they still linear?

 

S-trim is very linear, power comes on smooth and continues through red line.

 

Same with the T-trim . You just get more booost sooner and it builds all the way to redline

 

great numbers

 

Great numbers you can add 10 - 12% that will give approximatly what they would be on a dynojet.

 

Awesome Kevin so everything worked out great for you and your s-trim. I have mine on and compared to my friends coupe with the sc vortech I leave him about 3 cars back when we go at it. Major difference my boost comes on so much quicker. I am going to upgrade to the 2.87 and see what I can get right now i am on the 3.13. I need to get on the dyno better than street tuning with the e-manage.

how much was the upgrade to the s-trim impeller?

 

I need some internals first.....

 

Cat...Did you get your car back ? Hows it running , did every thing work out ok with the modifications ?

 

I did not see an answer but how much is the s-trim upgrade.

 

i am not sure of the cost of the upgrade as I had an extra CCW s trim to try out. I still have my SC trim supercharger. I think Kevin once said it cost in the area of 150-250

Wow that is cheap, I heard that the T-trim was like a 1000 so there seems to be a large difference, what is the turnaround time as I may just send mine in.

 

the sc-trim is eseentially an s-trim impeller that they cut down. I think that is right. Overall, they both produce the same flow and boost levels, but they have different rpm ranges. The sc-trim can be spun a bit higher (makes sense if it is lighter and a cut-down s-trim).

A t-trim wheel has different dimension than the sc- or s-trim wheel, that is why it is so much more to upgrade.

 

The T-trim has a different housing too . It has a bigger air inlet...4 inches
