Awesome - sounds good, so it has met your expectations without even leaning on it then? Hope the power delivery/response is good too :) I had figured it could be good for 450kw+ @ hubs on the right setup, but Dyno Dynamics are a bit of a mystery to me - never had any direct exposure to them so really I wasn't sure what to expect on one of those, though I had expected 370kw should be pretty doable.

Wow so it's not going to be driven at all until race day? No pressure :mellow: Hope it all goes well!

Back to the FP3794HTA - apparently Forced Performance have a prototype "FPxx94HTA" which uses the same compressor wheel as the FP3794HTA but has different housings and a different turbine wheel, the initial indications are that it is expected to spool quicker than the current PT6766 and FP3794HTA - but make more power than either.

The car that the testing this thread is about has had one of these units attached to it and will be getting it tuned soon - and no doubt they won't be holding back. if it If it does turn out to be a better all around performer than the best of the 6766 and 3794 combined then it is a hell of a thing :)

It is Boostin' Performance's AWD Eagle Talon - it runs a high compression 4G63 with lots of headwork etc etc. It has run into the low 8s at >170mph (ie, quicker and faster than plenty AWD cars with GT42s/GT45s etc have run) with both the PT6766 and the FP 3794HTA, so it is a good base for taking such a turbo to it's limit :)

More on this GT3794R HTA prototype, it is now released as the Super94HTA and apparently spools better than and makes more power than both the PT6766 and the GT3794R HTA... it has been tested on a Mitsi AWD drag car which has run the previous turbos and on a slippery track this weekend it ran 8.4 @ 177mph - huge MPH for a car running a T3 based turbo.

So anyone certifiable who was looking for something in the 6766/3794 size range - they are now available to buy:

First 7s car I am aware of running a single T3 turbo, using a .85a/r FP Super 99HTZ:

And an AWD DSM ran a 1000ft test run this weekend and lifted to hit 8.2 at 153mph also using an HTA - they only had an 8.5 certified cage and had suspected they MIGHT go too fast, hence lifting at 1000ft.... but were kicked out due to still going way too quick. Seems like there may be a couple of 7s AWDs and a number of low 8s ones running these turbos in the near future :)

Agreed, just pointing out it is still a large turbo - but it is SERIOUS business... especially when no one has pushed a 99HTZ to it's limits, yet.

A Supra owner in the US has upgraded from their old Borg Warner S467 T4 turbo to a T3 flanged FP Super99HTZ and picked up 15% more power with a huge increase in spool - they run a Powerglide and usually use a transbrake however they are testing for an event this weekend where the class they will be in doesn't allow transbrakes, so they did testing using a foot brake starting at low boost to see how much they could hold back with the foot brake and have already laid down a 8.97 @ 151mph... I suspect when they get to a meet they can use the transbrake and wind up the boost a few eyebrows will be raised - not that running 8s on a T3 based turbo with a Supra isn't pretty unreal as it is!

Not with the new turbo yet, today it was it's first runs - the turbo seems to have maxed out at about 36psi (with 280deg cams) but I don't know what boost it was running for the 8 - definitely not 36psi.

Here's a dyno vid (unfortunately they only uploaded to FB): https://www.facebook.com/photo.php?v=194348620749465&set=vb.173984302785897&type=2&theater'>https://www.facebook.com/photo.php?v=194348620749465&set=vb.173984302785897&type=2&theater

Dyno numbers will be a bit messed up due to the loose Powerglide - but a Supra running 8s at >150mph is going to be making north of 900hp to start with, it isn't running NOS and it did it off the foot brake with more boost in it.... so safe to say that it's already a pretty stout result :)

    • Honestly, for a daily I would gladly rock a Camry. The more disposable the better. People drive horribly out here and road conditions are awful.
    • Verify it's going into each of the 4 gears in normal acceleration, make sure the torque converter locks up over ~65-70 kph or so at low throttle opening. If you ease into the throttle at those speeds eventually you should get a "gear" between 3rd unlocked and 4th locked. It should downshift eventually if you floor it at 65 kph too. Get some Matic D ATF and drain the pan, check for signs of sadness in fluid and drain plug magnet. Top off to the correct level afterwards. If the transmission is worth saving you can drop the pan on a second drain and change the filter while you're at it. These are not complicated transmissions, at least compared to modern stuff.
    • A seat I find stupidly comfortable to sit in is the one in a friend's Merc Race Car. It even has the huge wings that wrap around your head. Best ever. Only issue is climbing through his scaffolding he put up in the doorway of the car... Ha ha ha. I sat in that seat for a couple of hours doing wiring. Another stupid comfortable seat I find, especially if my back is aching, is my OMP fixed back bucket seat too. I'll just sit on it when I'm exhausted in the garage sometimes to relax!
    • I just got off the phone with Dean from Vosta in Brisbane. They are the ones that do the replica seats and they have a shop full of seats for my to try out. Lovely guy.  I haven't decided whether to go genuine or replicas, I'm leaning towards Genuine at this point but who knows.  Also thinking the STRADIAs are the way to go VS the GIAS since they have a lower hip edge and would be easier to get into. Don't really like the idea of arm rests on the models to the right of this diagram either, maybe they can be removed?
    • From my own first hand experience, keeping power for a fun Street able skyline down at a responsive low 200 wheel KW, is the best. It makes it super drive able through the twisties, you're not just smashing mass wheel spin, or only able to open the throttle for a split second before being at absurd speeds. That said, plenty of people like being morons at more than double the speed limit on public roads and hence are happy with 600whp and seeing 200kmh fly up frequently and fast. Also, at that low 200, a GTR can still do a decent quarter mile, and with a bit of fancy  clutch work (foot, not the parts) can still beat many many cars in a traffic light gp, even in the wet.
