Go to a T-trim?

We've had pretty good results with a standard S-trim with our old setup, basically a stock bottom end 302 with SVO heads, Cobra intake, Lunati "E303" cam and an Art Carr race AOD. Best run was a 10.80 @ 128 on DOT Hoosiers.

This year we are running a CHP 342 stroker in a Sportsman 302 block, 8.5:1 compression with a ringed deck, out of the box TW heads, the big Lunati EFI cam (X303 specs) and an AFM Typhoon RPM intake.

The S-trim is not going to be able to get enough air in this beast. I don't have the $$$ for a completely new YS setup, so...

What larger head unit will fit in the standard S-trim brackets - T, J, R?

Thanks for putting up a site dedicated to Vortech users.

Mitch: You are very welcome! Please pass the word, the more users the better.

yes it should fit if you are using the heavy duty v-1... the "t-trim" is the same housing. a friend of mine swapped out his s-trim for a old school "j-trim".

That's why I can't upgrade the S-trim :( I'm thinking I can pick up a used head unit somewhere as long everything else is the same. I have a Renegade discharge tube with a big ol' mondo bypass just waiting for some serious boost :D

MoDo what are the variences in the bracketry for the HD version of the s-trim versus non-hd? I am curious to know because everyone that I know that is a Vortech-Head says you can put a t-trim head on s-trim brackets non-hd or hd...?

Then again when I talk to other vortech budz locally here they usually have a 6 pack accompanying them LOL! :D


Thanks MoDo!

yes you are correct on the brakets, i thought you wanted to actually swap impellers but you can only do that with the hd unit

I see! Thats right.. {brain fart} LoL!

Is it just me that has problems slipping blower belts,I get that thing tight but it still sometimes squeals and I lose boost. Where can I get blower braces because the brackets flex.

It is a NAPA belt maybe that is the problem? By the way,I bought the blower used and it was an A trim kit that was upgraded. Does that mean the brackets are weaker?

i used to have the same problem with squeal then a sudden boost drop... i had the belt tight and it didnt help. i coated the belt with some track bite until i got the gatorback belt from summit (22 bucks)... problem solved :D

How do you like the PMS, Did you set it up? Did you have to figure out belt length or do they have applications?

my pms is not installed as of right now, currently im using the stock computer and only using a diablo chip to remove the factory rev limiter. i know 3 people that use the pms and love it... they insisted i get it. i should have it in within the next few weeks.

my belt length is 54.5 for the 3.33" / 6.87" if you have a current dayco / gates belt summit can cross reference it for you and tell you the length needed.

I'll do some more research on the T and J trims to see what hp levels they are supposed to support and max impeller speeds.

Like your avatar Blowaway! I was born in DC but my folks moved to Vienna Va shortly thereafter.

I have had good luck with the Gates belts I get from Advanced Auto Parts because they always seem to have the 8-rib size I need for my setup in stock. I don't know about you guys, but I used to just cinch down the tensioner pulley bolts and then whack at it with a 2X4 and a sledgehammer to get it really tight. I tried my 1/2" breaker bar with a 2" extension this past week, using the 1/2" slot in the tensioner bracket that was actually designed for tightening purposes and got better results.

I'm gonna miss that 2X4... :cool:

yeah i was always nervous about putting that much tension on the front main bearing. with the goodyear belt i honeslty just pushed down on the tensioner with my hand and tightened the bolts.

Are they available in 8 rib? I change mine at least 2-3 times during racing season to keep them fresh, which gets costly.

yup, and they are only 22 bucks...

I'll have to measure the last belt I took off and get a size. I always forget the Gates code, which specifies the belt length in millimeters. I have tried a 6 rib Gatorback serpentine belt before, but didn't get much use out of it 'cause I bolted on my first supercharger right afterwards and had to get a diff length.

Thanks!

Hey Mitch, this is Gary Putnam from Salina Kansas. (you bought the SID from me). looks like your getting ready to step up the ole hot rod! Will you make it to WFC6 this year?

Shoot me an email - I don't think I have your address. I'll send you some pics of the car. It's now painted "Prowler Yellow". Not too easy on the eyes!

The SID is working great with the new combo. I spoke with Jim Larocca and asked him about tuning it up. He doesn't like SID setups and said I should go with at least 50lb injectors and a re-calced meter, then he'd tune it. I guess I'm just stubborn - I'm not gonna change it yet. I want to see what I can do with the car as it sits.

If we hit any big venue races, it'll be for spectating only. I believe all the heads up classes we could go into limit injectors to 8, and I don't like brackets or open comp. We'll run the local tracks, which have simple rules for 5.0 classes.

Mitch

Couldn't you run wild street? I bet the car looks pretty good with yellow paint, shoot me some pics. Have you noticed the Photopost section here on this site, you could put some there also.

Here is my email address

garyput@swbell.net

talk to you later Mitch,
Gary

I still haven't gotten any pics to ya Gary. I hate using our digi cam; it's nice but no choice of lenses so anything close-up looks "fisheye".

I'll work on it this weekend.

:D

I had a gatorback. It didn't last that long. For some reason I lost a few ribs. I run the gates

The brackets are the same for "S" & "T"..have done conversions..The "T" pumps out 1200 CFM of air at the rev limiter.No pers exp,but the "J" is rated at 1600 CFM at the rev limiter..I think the "T" would be a plenty..I have dynoed my car w/over 600rwhp & still digging at 5k, but ran lean..w/ a "T".am fixing the fuel this wk..

Modo,
We're waiting for ya to install that PMS and to come by and join the board. :)
