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.

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

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.

    • H1 is not the Humvee, but is the most road based version. Lachlan (HankScorpio) on here has a proper Humvee. He imported it a few years back.
    • Welcome Thomas! Sounds like you've made some progress. Are you able to drive it and enjoy it a bit now ? 
    • HUMVEE are fine in big open areas, but they are problematic on the street and tight areas As for reliability, some of the  US Army guys I have chatted with have said that when they were working they were fine, but, the do spend alot of time in workshops for multiple reasons, admittedly, they did get a hard time by the boys and girls who drove them I would definitely put them in the "buyer beware" category  They do look tough as nails though 
    • Just don't use ChatGPT or any other artificial stupidity for the equivalent of googling. Their demonstrated inability to discriminate reality from hallucination should be enough to make them totally untrusted. LLMs don't know anything and cannot think to even the smallest extent. They are just predictors of the next word, and that should never be confused with capability.
    • I think, given the usage model described in the OP, I'd never ever experience the wonders of the 400kW upgrade. What I really need is boost from 2000rpm and probably no more than 260-270rwkW. But I suspect that the highflow is not actually the turbo for that purpose, so I may in fact need to get a G25 or 30 or something right sized and very spooly. We shall see after it is tuned. I've had to back the boost and boost ramp off to stop the thing from pinging since the highflow went on, so I've been almost living the NA life for 9 months now! Injectors are recently in hand. AFM is in hand. Dyno is fixed. Just need to clear a queue of f**king Supras out of the way (and probably fit my new gearbox). So....some time this year? Lol.
