I Would like to see a balancing graph of a small turbo spinning over 200k rpm. Can you show that? Is it safe for a small turbo eg GBC14-200 to run at sustained RPM of 200k?
The balancing graph is no problem at all - we are bale to rotate to 400 000RPM in terms of the machines capabilities. Understanding the sealing system used on turbochargers, and the hydrodynamic pressure differential which is relied on to keep the oil inside the rotating assembly, it is not good to run a turbo at that speed for sustained periods. To get a turbocharger driven that fast will take about 5seconds, from standstill depending on the manner in which the machine drives the turbo, and what the inside of the drive cavity looks like. Some machines use accelerators in-line with the incoming air stream, which is highly restrictive for high flow situations/requirements but works very well for smaller rotating assemblies with lower air volume demands.
Very nice, would like to see the innards of Booshiwheel turbo, how is the poor performance made, is the bearing cartridge in an oval hole or what is going on.
Nothing to write home about - poor machining quality, and no attention to detail at all. Lack of knowledge is clear. The bearing system is backwards - once again lack of knowledge. Copying something at face value means nothing -- anyone can polish a turd.
Are you referring to a VSR test? Remember that the tests on the VSR are state of balance tests, and not flow plot results, which we have the equipment to do aswell, but this VSR test was dont to show the balance curve to prove that the cheap chinese poor quality (paper weight) was in fact a ticking time bomb. The bearing cartridge in the G25, G30 and G35 are all identical in the Genuine Garrett turbos - so the curve and consistency by testing any or all of these turbos will be the same.
No we have not - however from physical dyno time and seeing back to back comparisons on our own dyno previously, they seem to be really expensive products and do not outperform or outspool the current OEM products in the same family size and bearing category.
@@TurboDirectSA my xona 9567 cost is 2300$ us compared to g series at 2600$ us, but my next turbo will be a Garrett, probably a g35-1050 for my Mitsubishi 2.4 liters
YEs we have heard of them, they are a chinese knock off of the Garrett range of turbos with their name on the housings. The product does not use any OEM bearing manufacturers cartridge, however castings look nice. Will we spend money on buying one to test - No unfortunately not.
Alex Dinu not necessary as the bearing cartridge in G25 and the tested G30-900 are identical, the results will be the same (curve shape and consistency)
Thanks for the comment Goodwille, pulsar turbos are chinese knock off's of the Garrett range. They arent something we are interested in testing. We know that the bearing cartridges in the turbochargers are not supplied from a reputable bearing manufacturer in the turbo industry, and this is the main reason we arent interested in the tests of this range.
Could you do a side-by-side comparison with the copy and compare the graphs?
Youll have to watch the video where i expose the knock off piece of rubbish. Youll find it here:- ua-cam.com/video/7ElCF8rh3oY/v-deo.html

Amazing 😍 can i ask what kind of test can you make to see the difference between the gtx3076 gen 2 and the g30-770 ? Thx

Did you ever tested xona rotors turbo lines ?
No we have not - however from physical dyno time and seeing back to back comparisons on our own dyno previously, they seem to be really expensive products and do not outperform or outspool the current OEM products in the same family size and bearing category.

@@jeromelevesque8330 The EFR range is also something you should consider - especially the EFR8474 Black Series. Something i think will surprise you.
Have you heard of pulsar turbos? What's your opinion

Nice, can you do this test on a genuine g25-660 ?
Alex Dinu not necessary as the bearing cartridge in G25 and the tested G30-900 are identical, the results will be the same (curve shape and consistency)
4G ? Thats pretty shocking! how about running it to 120K?
Well done ! good to see this kind of thing. 👍
Thank you
