Atr43ss-2 Prototype Initial Tune 250rwkws 18psi<2500rpm, Stupidly Responsive

[hypergear]

I make this public. I've tested our ATR43SS-2 today at dr.drift. Here's the fun part:

Stock RB25det, 18psi before 2500RPM, made 249rwkws. car's tuned on 4th gear. 98 Fuel

Congratulations. That is amazing.

[battery]

nice! whats it like on the street?

[N1GTR]

Looking good!

Just to check, this is 100% bolt on to stock manifold etc?

What other mods did the test car have?

[PM-R33]

Very nice!

Here's the link of the video footage:

On road for normal driving its good, feels like always on boost. Once floored just wheel spin every where. 2nd Gear wheel spin from 3500RPM all the way to 7000RPM. Good responsive street turbo.

To bolton to stock setup need 2x slicon hoses, Exhaust and manifold plus lines bolton, can be high flowed into stock turbo.

Car's got 800cc injectors, Z32 AFM, FMIC, Exhaust, Clutch, BOV, Nistune chip.

what can you put together for a VL Berlina turbo that will bolt on...lines mani etc.

mint car that needs to look absolutely unmodified.

pm or post here.

[RBceffy25]

HOLY SHIT!

[Mr. Untouchable]

good work, good to hear it can be hi flowed into the stock housing also. I reckon you'll be selling a few of these!

What's special about this compared to ur normal ATR43?? what's different about it?

[Ruffels]

the boost looks like it drops down to around 14.5psi from 18psi ..... if you could some how get it holding 18psi to redline, im sure it would make more power....

also notced youve lost a bit of the bottom of the graph.... would love to see the bottom end of the power curve

[joeyjoejoejuniorshabadoo]

what boost controler are you using? if any?

[PM-R33]

What's special about this compared to ur normal ATR43?? what's different about it?

Yeah im curious about specs of this turbo aswell, what makes it so special to spool up and be on boost that early and that hard, yet still make allright top end?

This turbo was engineered for max street driving ability. Its more of a independent turbo that has no shared features to all other ATR43 models.

We've also done some testing on it using different actuators and settings with wastegate controller. I will discuss that in my thread lateron this evening.

Congratulations Stao, those are truly amazing results.

I find myself rather jealous

781nm?!? Is that right? Seems kinda high!

[Black_CSR]

I'm keen on the development of this!!!

[PM-R33]

781nm?!? Is that right? Seems kinda high!

Remember gearbox and diff ratios affect torque figures read on a dyno.

Yeah that seem massive but good:) Im sending my blown turbo tomorrow to get this done!
