Turbonetics Super 76 turbo

Just curious if anyone has used this turbo on a Buick. I was visiting the Supra boards and saw that these guys are making 1031whp with this turbo @ 6800rpm and 35ps on a stock unported head and intake (3.0L motor). Claims are they make more snort then the GT4276R turbos throughout the entire powerband. Low 900whp is what the norm is for a GT42 series turbo with all the goodies including ported heads, cams, intake etc. Any thoughts?

I dont have any experience with that turbo. But I have found that we can never compare anything Buick related to the Supra motors..LOL

Mike, I would stick with the proven track results with the GT42/76 IMHO.


Not sure of anybody who has done much in the Buick world with that turbo.

Mike,

If you're talking about this turbo, the specs look like just a 76GTS. (S-trim F1 wheel). Maybe Jack can chime in as he's a turbonetics dealer.

The 76GTS from PTE rated a 1100hp. and the Gt4276 at 1200hp. I think both figures are slightly high.

I swore that supra guys were making 1000+ to the wheels with the GT42's 74mm version.

The 42-76 has been in the 8's on several GN's. Our local track has a class with a 76mm turbo limit and every turbo car has a "variation" of the PTE 42-76. One of my customers has been 5.50's in the 1/8th on 275/60 DR's.

The Super is supposed to be good for 100 more hp over the regular T76. The regular being good for 900hp. I've run the regular T76 over the last 5 years and it seems to have done as advertised. I would guess the Super would too.

If you look at the size of the housings between manufactures with the same wheels you will see huge differences. A PTE76 weighs 19 lbs and a gt42 35lbs, due to big housings. One is going to make more power I'm sure. You need to look for the flow on the turbine side of the Turbonetics turbo and exh wheel size compared to other turbo's out there.

Thats pretty impressive. Just sitting there your turbo has 35 lbs of boost.

Can the hood close? Hey Norbs, keep at it man. Its the law of numbers, eventually your bound to get it right. Its like throughing enough sh it at a wall, something is bound to stick.

Yes the hood closes but I will have to use a blanket on the turbine side . I really can't give any more details since the combo has not been to the dyno yet. Since I was almost suicidal last time at the dyno I don;t want to go through posting a useless combo. Its just a measly turbo something like Don has.......

When a Stage 1 engine explodes at 35 lbs of boost it sends off an EMP. Electro Magnetic Pulse. It shuts down anything electrical within it's blast radius. I doubt if I'll be able to get through to you on my cell. The only thing I can recommend is to keep an eye out for a mushroom cloud.

No nitrous with the advanced spool up methods i am using. Too bad others in the buick community are not interested in making there turbo's spool like a stocker. But I;m sure you have picked up on it.

Man, I don't want to fab up more stuff on this biatch. If I didn't already have the killer nitrous system, I would definitely be making myself one of those. I would incorporate it into my T4/T6 adapter flange.

LOL

Nahh. I think it's great technology. I can't wait to hear about the results.
Just don't get that big monster turbo spooling up too quick. Don't want your engine looking like some blow fish popping out of the hood while the car rears up onto the bumper.

The 76GTS from PTE rated a 1100hp. and the Gt4276 at 1200hp. I think both figures are slightly high.

I swore that supra guys were making 1000+ to the wheels with the GT42's 74mm version.

From what I understand, the 76GTS has the exact same compressor and turbine wheels as the gt-42/76, it's just that the gt42/76 has a larger housing.

It's not a Buick, but I can tell you I went 155mph @ 3200# with a very mild 347cid Ford using only 6400rpms. We kept the motor mild and the RPM down to keep the consumption down and keep the turbo in a decent spot on the compressor map. I can see it working great on a Buick.

The gts turbine wheel is the same as the gt42 but it is clipped to fit in the precision turbine housing. This reduces efficiency a bit. The gt42 uses a larger housings on both sides, and thats why it makes more power.
