T trim ?
 

What kind of power can I make with a T trim with this motor?

Trick Flow heads ported
JE pistons
Eagle H beams (supposedly good to 750hp now)
Eagle 4340 Crank

The compression is going to be 8.5:1 when it's all said and done here in the next few weeks. The block is at the machine shop right now and I am getting ready to order a t-trim. We also did a splayed 4 bolt main just for added strength hopefully. What kind of power can I make using the t-trim? Do you think I can max it out on this motor?

Forgot to mention this is a 383.

Also any fuel suggestions would help. And will stock computer be fine for now? Going to build a T88 kit but that will take a while so the T trim is an option for now. Also cam suggestions would be appreciated.

~600-650 rwhp

That's it? Seems a little low. Are you sayin 600-650 with the stock 6-7 psi? I am going to buy a few different belts and pulleys until we feel we can't go any higher safely. I will probably have a FMIC made also and I have a bottle on it too if I need more power.

Well, the T trim moves around 1200 cfm. An SQ trim moves 800 cfm and makes 450, and our YSI trim moves around 1600 cfm and makes 800-850rwhp on a 414 cid, so I'm guessing the T trim is in the middle of those.

what kind of boost #'s are you seeing those numbers with though? I know CFM plays a big role in boosted applications. I am hoping to run 15-20 pounds with having a motor that flows incredibly well.

The T-trim is plenty powerful really...

THere is no "linear" power to what the superchargers can perform.. if you go beyound their efficiency you will still get gobs of power but not in the same way.

The T-trim should be able to hit 700rwhp.... but you will have a more ample power curve and better potential if you go with a YSi.

The YSI will bolt on to the S-trim brackets, so there is no problems with it...

Check out this guy

he did 840 FLYWHEEL pump gas on a 402 LT1... on pump gas...
he did 925 on 100 octane.. so the T-trim has plenty power

I am expecting more or less that on pump gas too with the YSi.

Chris Zorka did 160+mph and 8s so i guess he has a bit more than 850rwhp ;)

We made 775rwhp with a YS last fall and we expect that we can make around 850 with our YSI. We will dyno again in June.

I do not believe that a T trim can make 700 rwhp.

We have raced both a SQ trim and YS, and our YS did not bolt-on to the S trim brackets. We had to buy and modify T trim brackets to make the YS fit under a SS hood.

The YS and YSI use the same head units but the YSI has greater thermal efficiency.

I dont know.. my S-trim bracket FITTED PERFECTLY to my brand new YSI...

Since when is 650 rwhp "low"? That's good for 9's in a 3700 lb car if set up properly.

I meant low for what I thought the T-trim was good for. I thought you could make over 800 hp or close to it with a T-trim. If I make b/t 650-700 with the t-trim I will just spray on top of it also.

My 383 combo with sq aftercooler makes 510hp 490tq with 7.2 and 3.33 pulleys. The sq is good for 680 flywheel hp and 1000 cfm and is very efficient at lower boost high cfm levels ( good heads and intake system). I had vortec do a performance estimate on T trim and they told me to improve on my existing numbers I would need to run a cogged belt the 8 rib would slip guaranteed.

BTW the brackets are the same between the sq and t and the intake tube if you are using the stock one has a little spacer .25".

What, exactly, are your goals, performance-wise?

For now is to make over 800rwhp using the t-trim and a bottle until I am done building my own T88 kit for the car. After that I'll be looking for 1000+ on race gas for sure without the bottle.

It's going to be a true street/strip car. Not just a full out race car. It will have gobs of suspension work and will be able to handle. I love going to the track but want to be able to go through the twisties with ease. I can always set it up for the track if I want just by changing a few things but I feel it will hook fine the way it's going to be.

Sounds like you can get a YSi-trim and be done with it...

an 800rwhp car is not simple.... Even 700+100 on the bottle...

You need a very solid base to build on...

I advise you to get the BEST heads $ can buy... so you can maximize hp/boost.

I suggest you should coat at least the pistons...

you need lots of fuel management work and good fuel system... 96# will be a must... good fuel pumps also...

let me know

Thanks
