Wonder how dumb expensive that one will be.... I'd love to try some garrett stuff but damn it's expensive

I've got something for you then,
I think we call all afford a turbo now
Lol
It it in a gt4094 and a powermax.
There is a gt40 turbine in the 4088 standard that melts in a vgt as well. (Ford guys tried it)
I think a gtx4088 avnt would be sick.
Workstock vgt ftw!

Dang if I had known Santa was getting gift ideas at the Sema show I would have worked a lot harder at staying off the naughty list
I smell marketing hype at it's best...
Ok guys, please explain to me how you are going to make 800Hp with a stock lly compressor wheel made out of billet instead of cast??? That is exactly what your looking at right there, this is not new technology at all. I have attached 2 pictures of the stock lly billet wheel that I got out of GM's R&D test lab from back in the day when the LLy was being tested before it went into production. Lol, I have 2 of these from turbos I got from there. Most I have ever seen from any lly stock turbo wheel is right at 600hp and I'm not the only one. So where are they getting all this extra hp??? It sure as hell isn't the billet stock LLy compressor wheel and the 68mm turbine seems a bit small also. It took me a
72mm billet compressor on the 4094vgt turbo to get above 800hp so I can't see how they can claim 800hp on a 63mm turbo? Food for thought guys, carry on...

Vgt vs fixed
ball bearing vs journal
Larger turbine wheel and ar on fixed turbo is where the real difference is
Thanks I wanted to know what made it soo special because everything labeled gtx cost 4 times more then it should Imo
That's a twin scroll I just noticed too. I thought it was a vgt at first haha. I just assumed it was I didn't pay any attention
VGT vs fixed- Ok that's a whole nother argument
ball vs journal- This only applies if you are spinning it the moon(rpm) to make the difference in flow
Larger turbine wheel and a/r on fixed where the difference is- This is where I would normally agree with ya but the turbo picture and plaque they provided there at Sema says that it has a GT35 series turbine wheel in it which is way smaller than anything we currently use in the diesel market. The GT3788R turbo has a 66.4/72.5mm turbine which is the same size as a stock LLy turbine. The GT3788R is only rated at 675hp in the book. The most I have ever seen out of that combo is mid 650hp range on average. This GTX4088R has same size comp wheel but a smaller turbine so please explain how it's worth 150hp? The 68mm turbine is maxed at 32lb/min flow rate. The GT3788R is 34lb/min and the GT4088R is 36lb/min. Do you see where I'm going with this Mikey? The math doesn't add up here... Please buy one and prove me wrong here but you can't make that much power with a 63.5mm turbo, it took a 77mm turbine for me to see
700hp out of a Batmo 63.5mm wheel. What's the highest HP anyone has made with PPE's GT4088R kit?
My dad's truck made 654 to the wheels 4 years ago with stock injectors and a stock motor with a 40/88r and a .85ar housing, the tightest available. :thumb:
Nobody's really arguing against you on the 800hp claim... I'd say the wee size turbine and high power estimate are pandering to the WRX and Lancer Evo crowd more than anything, which makes them that much more outlandish since a spark ignition engine will never see the peak of that map.
SEMA=advertising not necessarily backed by science.
VGT turbos suck for performance lol
I agree Magnus on the gasser thing forsure, if you look at all the other chargers they make alot more power per size on the gassers. But mark knows his shit no doubt about that. If he says they won't perform like that on duramax I gotta believe him
Ok so we buy a gtx4088 and rob the compressor wheel, a core lly front cover set to put it in, and the back half of a gt4094avnt turbo.
If Garrrett won't sell the wheel seperate go to alibaba.com hahahah
