New "mid-boost" Supra Dyno #'s

[HellBringer]

Got my Supra back on the dyno with the fuel system and the old school turbo (replaced my short-lived dbb 6266) for some "mid-boost" tuning

Pertinent mods:

PTE 74GTQ .81ar -- old school dinosaur-tech..!
PHR turbo kit - (new style) open tubular manifold, single gate
4” dp/mp; Apexi N1 catback (necks down to 3” at the flange and then to 3.15”)
GReddy 3-row
Gforce ECU; VPC/AFC NEO
GSC S1 cams
GSC Beehive springs & Ti retainers
SupraStore fuel system -- 880cc injectors, Wally 400
VP110 fuel
100% STOCK Ignition - 4644's gapped at .032 - NO DLI!!


Boost numbers are peak boost, per the Peak-Hold on my EBC:

18.2psi 582WHP 471WTQ

19.3psi 597WHP 488WTQ

20.3psi 602WHP 504WTQ -- Fattened A/F

22.4psi 650WHP 523WTQ

23.4psi 675WHP 539WTQ

24.2psi 692WHP 551WTQ

24.8psi 700WHP 558WTQ


Switching to C16 before turning it up further. Can't wait to see what 30psi will do..!! I'll try to get it back on the dyno in a few weeks and go for KILL numbers! Should do ~800WHP on KILL. :bigthumb:


Here's the 700WHP Graph:

wow...killer numbers man...so jealous. :)

[bboyalan]

Damn Abram lol. Any pictures until then?

[green-lantern]

Very nice my friend!

[j2k4]

That's pretty damn flat...:)

[Unlogic]

That looks really smooth, give us a video!

[HellBringer]

Thanks, fellas. The car is an absolute blast to drive -- doesn't make a ton of TQ so it hooks up nicely, and absolutely rips up top! Looking forward to some C16 and 8xxWHP. :DevilSmile: I'll have the video up as soon as I get a chance to put it together. I'll try to get some more of the graphs up tonight.

[NOMIEZVR4]

What is it that allows you to keep tq curve from dropping like a rock? is it common for the 2jz or is it the cam/turbo combo, or what?

[HellBringer]

TQ doesn't drop like a rock because the setup is still very very efficient and well-matched. The cams play a part, but the engine is still breathing well and exhaust back pressure is still good. My old Supra with the T72 and stock cams still carried TQ fairly well. The reason say a TD04 setup looks like a bellcurve is because the stock cams were made for mid-range power, but even more paramount, the exhaust backpressure is sky high due to the teeny tiny turbine and exhaust housing.

[HellBringer]

Here's some fun comparisons:



Red: PTE 6766 jb .81ar @ 24psi, 264 cams, AEM w/ soft tune and VP110 (on a 213k mile engine)

Green: PTE 6266 dbb .84ar @ 19psi, stock cams, stock fuel, VPC on VP110

Blue: My current setup

I've got cams..and HL wheels with ported turbine housings(yeah I know they're not big despite being the biggest available in td04 land..lol) despite that still when comparing my dyno charts with yours or any Upgraded Turbo EVO's...it looks pathetic...godamn these cars have bottlenecks at every single point. I wish my tq curve would hold till redline like yours..

Even with bigger hotsides I don't think I can recall any 3/s dynocharts with a decent tq curve...something street-able...

[HilbillyHomeboy]

Really nice numbers, and super simple set-up. Well done, as usual. ;)

[HellBringer]

Nomiez -- HL wheels or not, it's still a teeny tiny TD04 housing choking the exhaust flow. A larger hotside and a proper aftermarket cam will carry TQ just as well if not better. The 6G72 heads are far superior flow-wise compared to a stock 2J head. Have you ever seen the stock ports on a 2J? They're comically small considering the power they make. There are HUGE gains to be had with headwork, but it's absurdly expensive..



Thanks, Jeremy! :bigthumb:

Nomie, put on dr1000-1200, keep your mild cams and put on a well designed short runner intake. The dyno will look just like what you are looking for. Fairly flat tq from 5-7kish. Also if it is stock block evos you are comparing to, they raise boost as rpms rise (induced boost creep) to minimize the tq hit on rods. The DR1000 graph floating around on other site is 800awhp and 6xxtq and looks very similar to hellbringers. You just need bigger turbos and better boost control;)

[HellBringer]

I've been slackin' on the videos but it's been a crazy week.. I'm on the list for a local dyno shootout this Sunday -- if the competition is similar to last year I should take the W. I may bump the boost up to 26psi and see how much deeper into the 700's that takes me. With the WHP/boost gains I'm seeing and the relatively low TQ, I think I should still be well within the margin of safety on the VP110 (on the dyno).

I'll get some good vid on Sunday! :bigthumb:

Added the video to the first post.. :bigthumb:

Noice! Do you drive around with music playing? I am looking forward to seeing the results of the FD too.
