    Who Has The Quickest Spooling 500-600RWHP Single Supra On Pump Gas?

    As my research into going single continues I would like to hear from members who are in the 500-600RWHP bracket, who only use pump gas. Ideally 94 but 93 would be just as good.

    Spec along with dyno printouts would be ideal.

    Thanks.

    A turbo that is capable of 500-600 whp on pump gas (limited to < 20 psi) will be much larger and therefore not spool as quickly as a smaller turbo that would easily be capable of the same power at higher boost levels on E85. If you're searching for a quick spooling setup I feel you'd be better off running a log style manifold, smaller turbo (i.e. 6266) and E85 making 500-600 whp at 20+ psi.

    I am currently making 460 whp on pump gas (16 psi) with a PHR log style manifold and JB PT6266

    I have the quickest spooling single on a "supra" on pump gas.

    You can read about my specs and dyno if you click on my Z4 build thread. Plenty of youtube videos of the car at the track showing you spool characteristics (search 2jz z4 on youtube). 600whp/500wtq - stock engine, can handle the abuse of road coarse. BW 60mm turbo.

    Well, on stock twins at 20 PSI I made 430whp/450tq, I mean if you add cams you are almost to your lower number nothing spools faster than the sequential IMO. Especially if you are on ceramic twins like me, i have 10 PSI on the first twin at 2000 RPM 15 by 2300 in 5th. Car is real fun on stock twins.

    You'll need at least a 61MM turbo to get you to your goals, the thing that you will want to look at is getting a mismatched wheel.

    Meaning getting a 61mm compressor wheel with a small exhaust wheel so that you can spool faster and sacrifice some top end flow. (kind of irrelevant because to max out your 61 you could get to 700-750 WHP)

    What manifold?
    What size intake tube diameter
    What size downpipe and exhaust

    Why only 14? you could jack it up another 8-10lbs...

    you're on 70/30 meth. He was asking for straight pump.




    I'm also seeking a wide powerband and superfast spool. I was looking at the GTX3582 , 6466 and 8474.

    I believe the G42-1200 series turbos may end up displaying great spool characteristics. I'm looking to see what the efr8474 can do.

    My old setup, 6266, cast manifold, QSV, stock long block made 565whp and was a tire fryer. Only concern was the life of the rods since the boost hit super fast and hard. FUN setup for sure!

    Holy shit that thing must of spooled stupid fast.

    What kind of spool time can I see with a JB 6766 on pump gas stock long block, Tubular manifold, divided turbo housing .84ar. ?

    My setup spools too fast as ridiculous as that sounds. I am on a Precision 6266 DBB on a cast manifold and 264 cams through a built auto with a 4K stall. I have tried a few different wastegate setups with 1 BAR springs and at wastegate pressure I am still hitting 19-21 PSI spikes on 91 octane. I think this is too much on my rods and feel as if my motor is a time bomb. Going to do a built short block this winter with billet mains and going back to a big lazy turbo.

    It should be insane with the 4K stall indeed! How do you like the stall?
    Wouldn't a 3200-3500 stall match better with the 6266?

    I didn't mind it at all. Boost was like an on/off switch as soon as you hit the throttle. I am doing a manual swap at the moment but it has been the best auto setup I have had.

    PHR intake manifold
    4in intake
    4in DP/Exhaust

    We didn't want to push pump gas numbers. It is right in the efficiency range, and because of the IM, and cylinder head, we didn't need as much boost to make the peak ##'s, not to mention, it is a very small turbine for this motor. The car only makes 630 maxed out on E85 on 22 psi, but it is very responsive.

    I have a similar setup to this now. But its a .68 ar non divided turbo housing, but divided manifold.

    Its not tuned atm, running stock ecu with maf and no boost controller. just running on the wastegate spring (smallest one).

    Full boost seem to be around 4500 rpm. boosting 13-14.5 psi

    6766jb CEA gen1, .68ar
    tube mani
    4" dp and md to 3" back
    tial 44mm wastegate
    greddy 3row ic¨

    Im looking forward to get this setup tuned

    After I was 6266 I went 6766, stock long block, cast manifold, 1.0 undivided. There is some lag but not much at all and it very fun on the street. I like the 6766 so much so that I am now going 10.5:1, built VVTi head, Billet S2's, billet mains, BC rods, etc... This car should feel like a blown V8 once I am done, haha!

    I provided an example with real world use (not just a dyno pull with random highway pulls). To run 600wheel on a roadcoarse will test the limits of everything, and sadly Meth/water is necessary in my case. I will start counting knock on 90+deg weather without it, especially no the long straights of the track.

    If you wish to run 600wheel on my setup/combo with random highway pulls in cool weather, Im' sure you can get away without the meth!

    Some really nice info posted so far, im really interested in what the cars are producing under 4,000RPM and how long the power lasts.

    6266 or GTX3582R is as big as I want to go, has anyone changed A/R to improve top end and noticed much of an impact in spool?

    dre99gsx - Your thread is great but unfortunately all the photos are dead.

    Boost Wang - Any videos or further spec?

    SupraWillis - Do you have any videos of the car being used in anger that your can post up?

    CzA - your set up sound very interesting.

    Twin2Turbo - I love your thinking.

    What kind of racing are you planning on doing with a Supra that you're concerned with power output below 4k? I understand the desire not to have a peaky lag monster turbo on a street car, but something like a 6466 up to a 6870 should come on around 4-4.5k, and with valvetrain upgrades you can rev it out to 7.5-8k. That's a nice broad powerband, just select the appropriate gear.

    Now that's weird. All the images are hosted (you can see one of them here: http://benchraces.com/img/z4build/20160709_201114.jpg), and I have another forum using the [img] tags with no issues. I wonder if Supraforums restricts linking images from certain sites

    Sorry... don' t know how to fix that one. The were working fine not too long ago!

    Now speaking of power before 4k, my peak torque of 500wheel is right about 4k-ish, and it's too much. Corner exits with that power require good large sticky tire. I actually leave it one gear higher so I can hit it below peak torque to allow the power to ease on. Something to consider... a bit lag isn't too bad of a thing sometimes with a huge power increase.
