The size of a turbo refers to the flow rate of a compressor wheel. Theres hardly any recent results of original 35r because 95% are running 35r with a billet compressor wheel. but here are some ~ flow rates of the compressor wheels relevant. all 85 results
turbo = size= lbs/min = whp typical on e85
35r =61.4mm= 68lbs = 650whp
hta3582=59mm=72lbs = 700whp
black =hta3582= 59mm=72lbs = 670whp (held back due to turbine housing)
25G= 60.5mm= 60-67lbs * = 550?? (so far wooho!) *original or billet
does that help?
This 25g to me is simply a mismatched combo of wheels. The compressor wheel is capable of 650 whp but its being held waaay back mounted to 6SL2 turbine wheel. not only is it held back in power but spool suffers as well. the 25g turbo would be waaay better if it was mated to 6H size turbine wheel. It is an inexpensive turbo that can make over 500whp. If working within extreme budget constraints then it may a be a good choice for people.

Okay, now we're getting somewhere. Love when numbers come out cause now its time to fix your facts.
Gt35r, Max air flow is 62 lbs/min. Usual dyno is around 600whp racegas.
HTA3582 or FPBlack Are 68 lbs/min not 72. It even says on the FP site.

The 25g is a 63 lbs/min turbo. All 25g's are different that's the problem. Some will have different exhaust turbine housings which limits them to the 550whp as you see etc. Mine is totally different. Again, I could have change my compressor housing to a 25g/t67 and I could have flowed an easy 67-70lbs/min with a billet wheel too. The 25g isn't bad. You just have to understand that it's not like a garret turbo. It can be manipulated and changed out and customized.

~ flow : that squiggly line means approximately. I used approximate numbers for comparison sake. the 35r wheel is quoted from garret as 68lbs. I have seen at least three setups make over 700whp on the 35r wheel. so 68lbs sounds about right to me. but to be clear the flow map you posted does not depict the turbos max choke flow.
fp black is rated for what whole turbo can do not just the compressor wheel. and again its just a rating for comparison sake. the green is rated at 54lbs per minute but we have seen flow at 58lbs through the motec on roberts own car.
I used the 25g wheel ten years ago and went 11.0 at 129 with it. and that was fast ten years ago for 93 octane/water injection. the 35r went on same car next followed by the 3582hta. I think i have a pretty good handle on flow rates and actual performance of these wheels.

It's the same with the 6758 EFR vs the 20g in the cobalt SS scene.
You have sand in your clitty. if you cannt take negative criticism maybe you shouldnt post???

I don't have a problem with negative criticism i do have a problem with uninformed and misguided personal opinions intended to bring down a product rather than to help the people that have chosen to use such product which is the whole point of this forum. Now don't you think that your response at the end of your post here was a lot better? 
if you really want to help people use your knowledge to help them out not to put them down, you'll see you will have way better results and gain people's respect because of it, just saying. And btw i do agree with your statement at the end of your post.

Switched out the 1 bar to the 1.5 bar spring... eh same **** in my logs and feeling. It's just horrible compressor surge. I'm guessing the turbo just took a **** or something... Time to buy a comp turbo 6262...

Payam if your fueling isnt right them you'll get cut out and get that surge effect. If james was just there and had his hands on your turbo its fine. It didnt take a **** in a couple weeks. Get the tuning and fueling sorted out and go from there. No need to spend another 3k and have the same issue on another turbo

pretty basic setup on e70. change compression to 10/1 and e85 and you will see 750whp from 35r.

Damn, that is pretty nuts. 40 psi or what? lol
Well here is a video of my car with 25g. Here tell me if you can tell compressor surge or wg flutter...

This is how I hooked up all my lines. Before it was worse, I did a hack job. Some guy helped me now it runs much better and it still surges as you saw in the video.
the line going to BOV has a solenoid in it that is causing your problem. the BOV has to have boost on top of diaphragm to help valve stay seated. car will run worlds different with this corrected. it needs dedicated line. no solenoids no tees.

Okay. I'll try that then. My boost lines were way worse than that. Once I did that I fixed it. My buddy with a 6262 is running his lines like that. Thats why I did it, and he has HKS bov. He told me to try a dedicated line to intake mani just like you said. I'm going to try that.
finally got my car finished on e85 with the 25g. I'm highly impressed with this turbo. absolutely a blast to drive. Big props to VIIIdriver and dmt tuning.
