Hey all -
As most of you know, about 1month ago I bought my new Supra. Well, I did a real quick phone call with the shop this morning for some dyno results:

541rwhp @ 18psi

Yep, believe it or not. No, I don't have the sheet yet to back it up. Like I said, it was a quick call...no rwtq...etc. Just a straight #.

Also, this week we'll turn the boost up to 35psi and i'll post results. The actual dyno sheet will be up by the weekend...hopefully (if I can get a scanner!).

later,
Jay

NOTE: This was done on a Mustang Dyno.

Hey Jay do you have a built motor? At 35psi that's alot of boost. I'm very interest in the munber at 35psi?

Yes, it is a built motor:
40 over forged pistons
Pauter rods
264 cams
5-angle job, ported/polished head
custom intake 12-injectors.

Jay - I too, am interested to see the #'s at 35psi!!!!

 

[98tts]

That one mean machine you got there.

 

[Rviscosi]

Nice Jay, looks like its dialed in nice at 18 psi, hopefully when the boost is doubled it will be dialed in just as good. Any predictions?

Jay: What made you change from a T 88 which is basically a larger unit to a T 76 ?

Remember - I kinda totaled my T88 Supra back in January (got ride of it the hard way!). . .this car had the T76BB already on it. Granted this car has alot more done to it, than my old T88 ever did. However, it is much more powerful and responsive.

Ohhh thats true my fault there in that miss Im looking forward on your dyno pull. Let me know how it goes.

 

[ttmkiv]

What shop is your Supra at? I am in the same area as you. Is it local?

35psi..

 

[Guest]

ttmkiv - actually, my car in not at a local shop. It's at Denko-Performance in York, PA - I used to live in Lancaster and I still take my car there.

Tozer - I always knew the T76 flowed alot of air...but more than the T88, I did not know that.

thanks,
jay

hmm, not too bad, I can't imagine the turbo was in its efficiency range at 18 psi... still though, sounds a little bit low compared to alot of the high powered low boost dynos we've seen, wonder if the tranny is very parasitic?

[Guest]

You have a level 10 right? are you going to change it over to an SP tranny?. Either way nice numbers, that car is a beast

 

[Guest]

Warren - thanks...I guess...sorry the #'s weren't higher @ 18psi. I'm sure there's alittle more to be had @ 35psi.

One thing to keep in mind here, that was 541rwhp on a Mustang dyno, which put a load on your car (unlike a dyno-jet). Mustang #'s are notoriously lower than a dyno-jet, which sucks since 98% of the Supra community uses a dyno-jet!!


Great One - Yeah, it's a level 10 and holding very well so far....If (when?????) it does happen to fail, if Level 10 won't honor the current agreement we have with them, then - yes, I will have to switch to an SP tranny.

Not really, if you see the article in Super Street Mag, they compare both turbos. Turbonetics T 76 Compressor uses 102.3mm/76.7mm Compressor vs T 88 which the Compressor is only 95mm/69.7mm, however the Turbine wheel from the T 76 is 68.4mm/79mm vs T 88 which is 72.3/85mm if you see the numbers are quite close, but the power Support for the T 76 is estimate at 850horsepower and 890for the T 88.
Just my 2 cents

Ah, what's 50hp between friends!

Hell, I still like the SP66 idea, I should be hitting the track next tuesday...we'll see how the big turbo performs.

later all,

Jay, I've got to say I love my T66. If you ever go to one, I'm sure you will too. Great compromise between power and response. That said, I'd kill for a ride in your T76 beast!! Congrats on the new ride! BTW, I haven't really had much cause to use the 2-step yet.... Have a hard enough time hooking up without it

HEY!
Good to hear from you...looking at your dyno #'s...no doubt you have issues hooking up!

If ever find your self on the East Coast, by all mean, I'll take you out in the T76Supra.

Jay,

what stall do you have? How does this combo drive? are you using an HKS manifold?

Dylan,
I have a 4200rpm stall, with an RPS header.
The combo drive remarkable well. Kinda revvy - but this is to be expected with such a high stall.

For such a large turbo, it is Very responsive, MUCH more than my old T88 Supra. As you can imagine, when the turbo come on, it's quite a kick, but driving around town is very acceptable.
