Bit of Vid from Issac Gett Drift running one of our ATR45SS1 turbos in a RB2530det engine. Car made a responsive 430rwkws @ 20psi on E85 fuel.

1000whp 300ZX is not something I come across every day. Powered by two of our ATR43SS-2 turbos externally gated on E85 fuel. Dyno maxed at 905rwhp @ 35psi

Actually Tao, Prabaths 300ZX did 940rwhp on Trents dyno maxing out the torque at 1200nm.

I bought a 21u g3 used and it has minimal shaft play side to side , none front and back, and doesnt rub anywhere. previous owner said he ran at 19psi on rb20. do you think i should be concerned with the side to side shaft play or is it acceptable?

[hypergear]

All turbos need to have a small movement in the shaft as the bearings relys on that clearance for rotation and oil delivery, you can that as bearing clearance. I say there should be nothing wrong with it since it came out of a fully working car. Assume its a bush bearing high flow, must make sure it runs an -4 oil line with no oil restrictors.

Going back to the Super responsive ATR45SS turbocharger, now fitted to an stock Rb25det Neo motor. High mount externally gated setup on E85 fuel. Car made 390rwkws @ 26psi, 22psi @ 3500RPM.

Sexual turbo setup for a basic build, great stuff Tao!

Updating on SAU about the latest result of the R34 GTR test car:

Back today at chequeredtuning with Tomei Pon cam Type B installed. Pretty interesting result to share as I never though it would make so much differences on a Rb26 engine. Using the same turbo and nothing else changed, car ended up making 444awkws @ 23psi, compare to stock cams, it made 31kws with 3psi less boost with waymore mid top end torque. It wasn't much laggier in response either. 

Car has:
Stock R34 GTR Rb26 with APR head studs
HKS Cam gears 0 inlet, 0 exhaust.
Tomei 260 / 9.15 Pon cams
R35 GTR coil packs
Trigger kit
ID 1650cc injectors
Twin 540 Walbro pumps+11m fuel line
Apexi FMIC
Trust 3 inches turbo back exhaust
PS2000
Nismo Front mount cooler
T4 high mount exhaust manifold
HyperGear 50mm External gate
HyperGear ATR45SS-1 Rb26 T4 Vband rear turbocharger
Final result of 444awkws @ 23psi

Great data as always Tao - I suspect the additional lift of the Poncams (although not sensational) still attributed to more flow/power

[GTSBoy]

Yes good. Now imagine how good it would have been with some proper cams.

[joshuaho96]

I'm pretty sure that these cams adjust the centerline and thus the relative timing of the intake/exhaust lobes no? I'd be curious to know what happens if you adjust the cam timing a little to get it back to stock.

[hypergear]

It was a back to back test, might be doing some tests on the next dyno run

Bit of vid of cam install and dyno tune

One more result to update. This is from a new version of ATR43SS-3 turbo. Car's an R33 GTST with a built Rb25det Neo motor with stock cams. Car managed to pull 466rwkws at @ 23psi, full boost by 4k, 520L fuel pump maxed. 

Details of build:
#KeepitReet Nissan R33 GTST Drift car
Forge bult Rb25det Neo engine
Nitto Pistons and Con-rods
HyperGear ATR43-SS3 Pro Externally gated turbocharger
6 boost manifold and twin Turbo smart 50mm gates
ID 1650cc injectors + Walbro 520 Fuel pump 
Forward facing plenum 
Front mount PWR intercooler kit 
Fuel system maxed at 465rwkws @ 23psi, E85 fuel.

Twicked this turbo alittle bit, Made same power, picked up another 500RPM of response and 100kws in mid range at same boost level or 23psi, still running out fuel even with an extra pump.  I think the original version of SS3Pro would peek 70kws more at full capacity.

[Ben C34]

Wow!

Very spicy, what dreams are made of. All in by ~4000rpm and making those numbers.
