1st Impression S/T-Trim swap

**eades5.0** · 11-15-2005, 09:56 AM

So far it obviously feels better, but a few points I wanted to touch on that jumped out obviously different.
1. Suprising still makes the same low end boost as the S-trim did
2. Sounds about the same at idle (V-1) but hear more blower when driving
3. Its a pretty violent supercharger when it comes on..unlike my S-trim (smoother)

Right now I'm only seeing 6psi and then by 5k it falls back off to under 5psi (very loose belt), I'm still running my S-trim tune so not taking any risk here (have learned the hard way)

All in all I am pretty happy, the car felt real strong on such low boost...but then again I havent had a supercharger on the car in a month..so take it for what it is.

I think my overall goal of making about the same power as I did on the S-trim but at a much lower impeller rpm shouldnt be a problem. I was working that S for everything it had.
More to come in a week or so once I finish up my fuel system and re-tune the car.
The reason for swap was my S-trim needed a rebuild, while at Vortech getting rebuilt a buddy cut me a deal on his T-Trim I couldnt pass up..but hes the smart man..loosing the belt finally

Thanks
Chris

Your t-trim was pretty loud i like it. Does anyone know how it compares to the sound of a YSI?

TONS LOUDER than the YSi The YSi is less than the S-trim as well.

Wow man, nice ride!

Sounds about the same as my coupe with a T-trim. It's not very subtle, sometimes I'm glad, other times I wish it were a little quieter. I'm very impressed with the T's performance though, the boost comes up to 14lbs at about 2700 rpm's and stays at 14-15 up to 6000. I'm sure the belt is probably slipping alot, but I'll leave it that way until I can get a Dart block.
