These are pics of my friends T-91. He's putting this on a mustang, hoping to make over a 1000hp at the wheels. Undoubtably the BIGGEST turbo I've ever seen in my life.

Orginaly made for a diesel locomotive:eek:

I took these with my handydandy phone digi cam thing:D Enjoy

Jebus... any idea what the turbo lag is going to be on that?

[Natty]

Holy ****! What kind of mustang is it? If that thing ever spools up... :p

Are those tiles one square foot each?

[Foxcolt]

It's all bout cams. or cam in his case.

He's hoping spool will start at 1800.

or...those could be a 4 month old hands and feet :D

um......not to burst your friends bubble or anything but unless you are running nos in it as well that thing isnt going to spool no matter HOW MUCH hp your pushing until way over 5000 rpms. there isnt enough exhaust gas in an entire mustang engine to get that spooled by 1500. Even then the turbos effeciency range is probably in the 10000rpm range on a motor as small as a mustangs (compared to a 18 wheeler). So basically, the turbo will spool at 6000 rpms, the mustang will redline at 7500, so you have about 1/2 of a second of power when the turbo is making power instead of using it. Ooh well. Good luck though.

I said it will start spooling at 1800. Remember lag is a term never used correctly.

We have no idea when it will reach boost. Hell the guy doesn't even know what he wants to boost to:D

This is the guy that I've always gone to when I couldn't anwser a question myself. He's colaberating with a lot of people on this. People that have been tuning mustangs/lt1's for much longer than I've been alive. I'm 99.9% positve this kid knows exactly what he's doing. I'll update you guys when I he gets done with this project

:) i didnt mean to come across as rude earlier just typing fast and I looked at it and it sounded bad. I know alot about turbos and even though your friend knows what hes doing, I just seem to think its overkill and I dont truly know if the output will be worth the trouble. A Supra is a 3 liter and a t-66 t-78 will EASIALLY push those into the 1000hp range if the rest of the motor can keep up. With turbos bigger isnt always better and it always comes down to what your rev limit is, and finding a turbo that effeciently operates in that range. With a turbine that large, you probably cant even push 4-5 psi unless the motor is built to all hell and back cause its probably pushing bagillions of cfm's into the motor. I dont know what an average boosted stang can run I only guess 7-8 psi since it is NA originally. let me know how it ends up turning out because I am curious to see not when the boost starts to build, but when it actually "kicks in" and knocks your head into the headrest and makes you try to grab the ooh **** handle only to end up smacking yourself in the face from the g-forces. :P Im guessing it will be around 5500-7000rpms, and unless you have a 9000 redline, youll be lagging every time you shift rather than staying in its optimum range.

You're forgetting something: displacement

At 6500 rpm, that 302 (could be bigger in modded....351, 383...) is pushing a LOT more air than a 3.0 liter/182 CID I6 (568 cfm to be exact). At 7500 rpm, the 2jz will be squeezing out a paltry 395 cfm...the 5.0 hits that airflow at 4520 rpm. And if a T88 can work on a Supra motor, it would work even better on a 5.0.

Obviously cams and other engine work will change these numbers...but I'm just offering something for the argument. I don't think the turbo is *that* much oversized. In fact, I think on a built 383 with a set of good cams and a LOT of fuel, he could stand to make HUGE power. Only thing I would have done differently? TWINS.

AGREED!!! I dont know mustang engines worth a damn, But i do totally agree that going with 2 smaller twins would have a much bigger advantage. Also note though that on those supras running a t88, they still arent hitting their boost until late in the rpm ranges and have their rev limit set back insane amounts, and an inline 6 can handle high rpms far better than any mustang engine can. So you are still looking at hitting your desired boost late in the rpm band regardless of the compensated added displacement and exhaust cfm's. Only reason I say it might be too big is because on My eclipse, i had a custom done turbo but the impeller wheel was a t3 turbine. the housing was alot smaller so it wont push as much air as a true t3 (this was on a 2 liter though, so I was going for 4000 range spool with 650 - 700 hp potential out of the turbo. That turbo at 1 bar pushed 860cfms. This really has no relevance to the mustang only that from the looks of it, that turbo is going to want to push massive amounts of power. The bigger the engine, the bigger the turbo can be but I personally like turbos to stay spooled, and if you can only run it at 4 psi ( I have NO IDEA what a mustang can/will run at ) id prefer a slightly smaller turbo spinning just a little faster that most likely is a little more effecient, as long as it isnt spinning too much faster to start producing heat. All pesonal preference though I guess. Different engines, different methods. But the twins idea would be sick :)

[240racer]

the only question I have about running such a huge turbo on a V configuration is how are you going to do the header. I can't imagine this guy is going to run two of these things. I would always run a twin setup on a high HP V engine. I saw a twin turbo mustang this summer at the drag strip running at about 186mph I think. That thing was pretty cool

:eek:


Thats f uckin beefy as hell.

[SaintlyCharBoy]

naw - go for this one!!!

Yeah, I bet those Supras spin to like 8500 rpm, right?

I'm wondering about that turbo, actually. Jed said it's from a locomotive diesel...meaning that it operates at a VERY consistent rpm and within a VERY small rev range. I think those redline at about 1500 rpm. I'm beginning to think this turbo is a bad idea. It probably has a *really* small A/R and trim.... But I could be wrong.

About Mustang boost...with enough effort, the small block Ford motor can handle it. Forged everything and a nice new block. 20 psi isn't unheard of (mucho gas-o though).

I still think the twins would rule. I saw a drag '57 Chevy with twins that were routed up top and stuck out the hood...they made ram air for them. W0W.

Oh, and about the header (the other guy asked)...you bet its' gonna be tricky ;)

Hey, where did you get that picture of my "BIG" T25?

[Foxcolt]

Sorry haven't read all the posts so I'll probably end up editing this one.

Eric. All I personaly know of this turbo is it's got a 1.0 AR trim on the exhaust wheel.


240racer. He's using two hooter headers originaly designed for a twin turbo setup.


This is an overbuilt 5.0 motor. We know that the motor will have no problem taking the hp. Believe it or not his tuner wants to limit the revs to 6 grand. Don't ask my why as this far surpasses my limited knowledge on cars.

To keep in boost he's going to be using a new boost controller that utilizes a CO2 cartridge to somehow regulate the twin wastgates he'll be using. Unfortunatly I don't know much about this boost controller either.

He's hoping to have this finished within a month so I'll deffinatly put up dyno sheets when they come in.

Well, I am aint goin to say any technical stuff. Just got to say, JESUS CHRIST!! THAT IS A BIG MOTHER ****IN TURBO!!:eek:

[MorganS13]

i know 2 guys around here with twin turbo 5.0s and a lot more with supercharged stangs. they'll get u moving pretty well ;)

i also know 2 other guys around here running single turbo LS1s but i'm not sure how they're running their setup...

No offense taken:)

[uiuc240]

that's cool about the A/R. i'm assuming we won't hear more about this project for a few months....

Eric

[Nismos14]

oh man definately keep us posted on this, is there a website that we can see the progress of this car??

[kandyflip445]

Ok, how big is the locomotive engine...compared to the 5.0.....I would imagine a locomotive engine would be a LOT bigger...but who knows. Definately not me. And yeah you should really post when he gets it done. ALONG with dynographs. I wanna see them too.

EDIT: AND WHERE THE F*CK IS HE GONNA STICK IT IN THE ENGINE COMPARTMENT??????????
