Looks like spool will be very close to stock turbo levels or within a couple 100 rpm's. Test your car in 3rd, 4th and 5th by starting at 2000 rpm's and checking what RPM you hit 20 PSI with the stock turbo. I also like using 5th gear as it actually gives you a chance to get consistant results since the boost doesn't jump up as fast in taller gears. If Buschur said 2800 in 5th with an exhaust system and intake mods that is right about stock spool. Tuning and alchohol injection would be the only other variables and I'm not sure of his test car's setup.

I'm beta testing it for them now. On my 21G from turbochargers.com I made 17hp mid and 12hp on top w/ compressor surge problems...I 'm going to take it off and send it out to get clipped which eliminates the surge. But there selling them now already clipped so you dont have to worry about the surge....I think Buschur is supposed to dyno there car with the 21G mid week and let us know the numbers.

I tested the newest version of this turbo this morning and I am very happy with the results.
Spool up is very close to the stock clipped turbo that was on the car. I am getting over 20 psi by 2800 rpm in 5th gear with the car.
The boost doesn't spike as much as it did with the stock turbo, it is hitting 23 psi and then holds 21 psi to redline. This is much better than the stock turbo which will hit 25 psi on the spike and be down to as low as 16-17 psi by redline.
This turbo unclipped gained 2+ mph in the 1/4 on my RS a few weeks ago. We clipped the turbine wheel to get rid of the compressor surge problems we were having with it.
The turbo has NO surge on my car while accelerating now.
I will get to the track next week and do some testing.
These will only be available clipped as they surge violently without the clipping.
The clipping increases the exhaust flow.

David:
why dont you put all your turbo options on your web page for all of us Buschur fans to see. You have had the same turbo page for 1 year now.....
Any cam will be fine for this turbo.
The best thing to add with this turbo is OUR FMIC kit if you are adding one with it, the alky kit would also be a good choice as the higher boost that is possible with this turbo could be used.
The prices have stayed the same, the clipping is done by machine, it is not cast into the wheel.
Updating the turbo page is a good idea, but there are more updates coming so we are going to wait.
