I think this is a great priced turbo and looking forward to what it does over an is38

[@stratifiedauto]

Very soon we will have the tuning results and video.

[@acefighterpilot]

Great video, appreciate the depth and measurements.

[@stratifiedauto]

Thank you!

[@TJ-rd6fo]

Would love to see some tuning results of this turbo on an ea888 running pump gas.. fingers crossed you have a video planned! How does the bearing system and shaft diameter compare with an is38? Now that I heard the new RS3 isn’t coming to Canada, I might have to juice up the MK7R.

[@stratifiedauto]

We will have this soon. Did not take shaft apart to measure but Garrett turbos are quite reliable.

[@alv9672]

Nice analysis! Can you do the same analysis with the larger garrett?

[@stratifiedauto]

We will look into this. For now let’s see what this does on the dyno.

[@superfalcon022]

Great video very informative and intriguing!

[@bret1700]

Still waiting on results... can't decide if I should install my ticking time bomb IS38 on full e85, or run this turbo on pump gas

[@stratifiedauto]

We’ve had the results posted. About 40-50whp more than is38. Both on pump and ethanol.

[@bret1700]

​@@stratifiedauto o wow seems like a pretty solid turbo at this price point.

[@Robymk7.5R]

Bypass valvle It s the same? I got dv+ on my is38,can i use It on Garrett?

[@stratifiedauto]

Yes it will fit

[@bennyrs1]

with the powermax, only the compressor wheel is larger than the vok is38. and that should make more power, I doubt it

[@stratifiedauto]

Watch the whole video. It’s a completely different turbo.

[@TheUltimateDIY]

if you mount the stage1 turbo on an entirely original s3 8v, do you still have to do a reprogramming? or can we mount it and stay with the original program?

[@stratifiedauto]

For it to run optimally you should get it tuned.

[@TheUltimateDIY]

@@stratifiedauto and if you mount it on an original car, what happens without reprogramming?

[@stratifiedauto]

Poor boost control and throttle closures.

[@TheUltimateDIY]

@@stratifiedauto what do you call throttle close? car going into degraded mode? concerning this turbo on audi s3 8v can we limit the power to 400hp in ethanol?

[@TheUltimateDIY]

@@stratifiedauto ?

[@Di-Mit]

Do you use adapter for oil hose and water ?

[@stratifiedauto]

We use the ones with the kit.

[@Di-Mit]

@@stratifiedauto it is mandatory ?

[@stratifiedauto]

Yes I recommend using what comes in the kit.

[@Adrianperformancequattro]

What is max boost pressure in bar?

[@stratifiedauto]

We run it at just under 2 bar peak.
