Given an average blower condition, how much do you guys think it would cost to upgrade from a V-2 SQ S-trim to a T-Trim?

Out of all who have done this already, was it worth it afterwards? I'm currently doing 12psi with my SQ S-Trim(w/aftercooler), and thought about going up to the T-Trim to get more power. I don't really have a power goal(per se), just want to spin a T-Trim to the upper most safe rpm limit, while keeping the A/F ratio at or around 11.5.

With engine analizer I seem to come out at 535+\- rwhp. The motor is built for boost and I'm running the dreadded cc305 @114 lsa. Which brings up another delima, what cam should I go with. I'm trying to figure this out, so don't feel like commenting on that one because I don't have my new flow numbers due to my heads are currently being worked over and freashed up again. My CR will be around 9 to 1 or 9.1 to 1.

Just wondering what are the pros and cons to stepping up to a T-Trim. And from those that have done it, would you recomend someone else to do it.

 

I can't think of an cons to stepping up to the T-trim, you will only gain performance. As far as price, do a search here and see what some of the T-trims have been listed for in the parts for sale section, it will give you an idea of about how much they have been going for. I have seen some pretty good deals on them in the past.

As far as the cam, when you get your flow numbers, get in touch with an engine builder or a cam manufacturer to have a custom grind made. There was a thread a few days ago about custom cams and guys here on the board seem to be satisfied with SStrokerAce and the cams he sets them up with.

 

vortech has an exchange program.....usually $1000+ upgrade with the trade in.

the info is on the site........www.vortechsuperchargers.com

 

One con is the T-trim will make way more noise. That is one of the reasons I went to the SQ trim. It is nice and quiet.

Maybe vortech will eventually make a quiet t-trim or larger blower with helical cut gears, kinda similar to the Paxton Novi 2000. Apparently the clearances are way tighter with those gears vs the straight cut type.

I am happy with my S-trim, SQ version for street driving. It makes more than enough power.

 

i actually wish that my SQ was louder. it is literally silent above 1200rpm, and very very quiet at 1000-1200rpm.

 

I was in the middle of making a decsition to step up with the Z. The T-Trim being the biggest piece. Running through the heads again and choosing a new cam, I figured the next thing to look at was the blower. There will be that noise I'd have to listen too
