With the MPS wheel will it spool sooner or later than the stock wheel? What exactly is the TC76 turbo my shop out here in Ca looked at it and thought it was a 67mm housing on the compressor side is that true? Is it the smallest compressor housing available that will hold a 76mm wheel? Thanks

The compressor side is a 62-1 wheel.

It will spool very fast, so you have no worries there. It is indeed a 76mm turbo though.

Full specs to this turbo are here:

TC76MPS Turbocharger Specs:
Compressor: 62-1
Bearing: Standard bearing
Turbine: T4 S trim (formerly Q trim) Tangential undivided housing with a .96 A/R
65lb/min = 705 FWHP.

This info is directly from Turbonetics Tech staff so you can take it to the bank that it is correct.

The exhaust side will support 1K FWHP, but the cold side will only support 700 FWHP MAX.... if that.

Those specs are incorrect. I can't post the flow #'s due to confidentiality constraints, but on a independant SAE test stand the turbo supported:

91.12lbs/min @2.612 PR

Max Speed 94,254rpm

before choke flow was reached. Just my .02 cents. Also look for a BIG turbo test coming soon....ala (The Turbo Shootout )

Also this unit does not use a Q-trim, renamed. Q-trim wheel from T-netics is on the right pictured below.

Does that mean the max power potential for a 346 is only 700fwhp? What good is a 900hp exhaust if the intake only flows to 700? What kind of power does this turbo max out at on a 346?

Doc, no disrespect to you or Jose....gotta say that first because you guys are an asset to tech.
I see S trim in the specs listed below. Robert and Co. at turbonetics gave me the specs of my turbo directly off the PN listing on the side of my turbonetics box. Since it was dropped shipped directly from turbonetics I don't see how the info can be wrong. Unless I was told I was getting one thing and sold another, but I'd have to believe Tnetics as they put the turbo together.

Why would Turbonetics tell me the turbo is only good for 65lb/min...they areN'T trying to sell me something or trying to upgrade this to a bigger unit. Once again these specs were derived from the PN's/serial number on the side of my Tnetics box.

I don't know what power that it will max out at on a 346ci LS1, just what I was told by turbonetics. I'll be looking for results from the turboshoot out that Dr. Turbo mentioned and i'll still be pushing my TC76MPS for all its worth as well.


If it does indeed flow 96lb/min thats a hair past 1042FWHP.

Jer, I dont understand how its a "76mm turbo" if it has a 62mm compressor wheel??? believe all T60-T76's have the same turbine side wheels (example: T67 Q trim has same turbine wheel as T76 Q trim)... its the compressor side that varies in size... which classifies it as a certain size turbo.

Measure your compressor wheel if you have a chance.

Don't know, i'm far from a turbo expert and i'll let the turbo peeps tell me what it is and both FI.com and turbonetics do state that its a 76mm.

It'll be two weeks before I can even get the turbo off the car, i'm in the process of starting to move into my new house

Your turbo is 76mm inducer.102mm exducer. Thos turbos are specd by us and the part # you have is correct. The problem is the info T-netics gave you is wrong on HP levels. That same unit is the above unit flowed. Some guys over there aren't the sharpest.

We just did the walk today, final sign off is this coming Tuesday and then we will be handed the keys

Doc, this came from their tech dept, the guys who built these things. Other than that i'll have to see 3rd party proof that the TC can support this kind of power for me to not believe the guys at turbonetics at this point. I've been all over supraforums, turbomustangs etc with no mention of the TC series on any of these forums...which led me to start asking questions to where I knew I'd get the specs, turbonetics.


Trust me I want to see this turbo perform to the highest levels, but with all those that were "sold" here on tech and abroad I have seen nothing.

Feel free to post up dynographs, vids, posts of people who are making power near what the quoted 96lb/min would support and i'll be stoked. I'll push my TC for all its worth.

I am gonna have a dyno graph in about three more weeks. We are going too max it out on pump gas? Shootin for 600-650 rwhp.

Josh@KY-Turbo

I would like to see some dyno results also. I use this turbo in my turbo kits based on the info that Forced Inductions gave me.

I am wrapping up the build on my shop car now. As soon as it is completed I will hit the dyno and see how this turbo does on a 370 cube engine.

I'm really looking forward to those results.

Josh@KY-Turbo

iTrader: (120)

You and me both. I have been working my butt off to get the car ready to go. Between working at the plant and running my turbo shop I dont have much time for my own car. I am shotting for some big numbers out of this setup. If I am not happy with the results I am gonna swap a PT88 on there and see what happens. I know once its done I have alot of tunning ahead of me. Thank god for the EFI Live/RR software and the new release of the the real time open loop fuel correction that is comming out very soon.

When do you expect to hit the rollers? I should be on them by middle of Feb my motor is at the machine shop now. I will be running 347CI unlike your 370. Anyone else have dyno numbers for the good old budget TC76MPS?

I ended up selling the mock up kit I was going to run on the shop car to get the funds together to Sponsor LS1Tech. I am stepping up to a full tube header setup with a big single. I just havent decided if I am gonna upgrade tig welders from an Econtig to a Syncrowave 200 and make my own headers or buy some of OFI's and use them. The competition around home has gotten fierce and I have to run with the big boys.
