OK, So here it is!

I got my blower back after 19 days from the day I shipped it in. This was an upgrade from a V2 S-Trim to the SI-Trim impeller as well as a straight polished discharge. Total cost was $730 which included the volute and impeller upgrade as well as a minor rebuild and shipping. If you dont want a rebuild the total cost would be $330 plus shipping. I was advised to do a rebuild not because my blower was out of spec but because he said the SI-trim spins faster and would benefit from the newer style bearings. Basically for good insurance, not that the rebuild was because of shaft play or bearing noise.

They also sent me back my original S-trim impeller and volute! Here is a comparison via pics:
its hard to see but the impeller is definitely larger on the SI-trim, the curved sections are much more pronounced.

I will be installing it as well as my front mount intercooler in the next couple of weeks, stay tuned!
 
yeah, here are the specs:

S-Trim:
1000CFM
20psi max
72% efficiency

SI-Trim:
1150CFM
28PSI max
78% efficiency

Its supposed to be a much better blower. The thing Im most looking forward to is the efficiency, im wondering what it is going to do to intake temps.
 
Oh yeah, this impeller and volute is designed for the V3 blowers that are self contained units (no oil feed/ drain). apparently they can be retrofitted to the V1 and V2 units as well they just wont sell them outright.
 
thats what im hoping for, thats a huge jump from what I had. The boost is supposed to come on much lower too in the RPMs too.

its like the T-trim

yeah, totally different from the YSi

although the efficiency is supposed to be the same (78%). I can say that mine runs very cool intake temps. But Ive also got a large FMIC.

Good luck. The step up from s to t-trim is a nice feeling

Yeah, the YSi is way bigger, too big for my engine. Ill be running a front mount too (31x12x3) so I hope to be about 20-30 degrees above ambient
 
I have a YSi, but my combo isn't even close to done yet.

I picked up a newer procharger 2 core intercooler that I'm going to front mount, but all of the tubing issues need to get done. I'm thinking about taking it down to Team Z and have them make up some nice stuff for that, but we'll see how money goes....
 
Yeah, I bought cheap aluminum piping off of ebay (yet to show up here) and Ill fab it up myself. Im a good 2-3 weeks away from firing it up.

Still debating what to do with my MAF, wait to see if my draw through and bypass valve is up for the task or buy a blow through and blow off valve....

mine is usually about 15 above ambient

the ebay piping works fine, i got most of mine from there as well as t-bolt clamps

go with the blow thru maf and biggest bypass you can, youll have alot less surge issues
 
Which MAF do you run? I can get a PMAS 3" pro-tube for $225 but dont really know the quality of those specific MAFs. I wonder if the new Abaco MAFs are as good as they say too. they are $400 though.

how big is "big"? like 50mm+ or is 50mm too small too?
 
I'm going to be an odd ball and run a blow through carb.

I spent a couple bucks and got a monster procharge blow off valve. I figured it couldn't hurt to spare the impeller and whatnot if I ever decided to move up to a cog belt setup from serpentine.
 
Have you pulled the bumper off yet and see how that intercooler is going to fit? I have a procharger 3 core standard with is 27 x 12.5 x 3 and I'm unsure exactly how it's going to go.

I'm assuming the lower you can mount it the better so it gets max airflow.

I should pull the front bumper cover off this weekend and start to eyeball things.

Not too many people put this much effort into what you are doing, I see fox body A/A setups on corral and stuff and they look like total shit.. I am looking forward to seeing your finished product, you may inspire some people to sell there aftercoolers, I know I hate mine... Its more work than its worth.. good luck man and be sure to post up lots of pics!!
