OF COURSE with a straight race gas tune he would have mad signioficantly more power
ALSO - he was NOT tuned for methanol injection as you were tuned
Creamo3 specifically asked that his tune be left conservative and safe - zero risk
With a more agressive tune and methanol he could have easily reached the very high 300's if not 400 whp with that turbo
REMEMBER ALWAYS gentlemen - dynos are for testing and tuning only - we race at the track and that is where you discover how fast your car is.

i don't think we should judge it all based on the evo 8 20g when the evo 9 one hasn't been in any cars at all (apart from the buschur one).

So true Dave. There are so many bandwagons on this forum, it's almost useless to come on here anymore.

BR says they have a surge problem, you buy the turbo anyway knowing full well it surges, then complain about the surge on the internet? Why would you assume it woudn't surge on your car, but does on the test car? I know Dave has mentioned compressor surge in just about every single 20G thread he has posted.
That seems to me like just a bad buying decision and unrealistic ecpectations.
You probobly should have waited to buy the turbo AFTER BR solved the surge issues.

trinydex,
What I said was as you said, "I wouldn't release the 20G until I was satisfied with it." 100% accurate and that is exactly what I did. I released it when I was satisfied with it. I am still satisfied with it and and still proud and glad I released this turbo. The normal 20G in the EVO8 cover surges atleast 50% LESS THAN A NORMAL TME NON 20G TURBO. In a car set up like mine a TME surges so violently that it is nearly impossible to drive. This makes the 20G not only acceptable to release as-is but with less surging than something Mitsubishi themselves built. Also, go back and re-read the posts made by the guys you are saying are so unhappy, as they have explained they aren't that unhappy, they just don't like the surge. They have even said the turbos work well.
The "problem" with dealing with a company like us is even if we build a really good part, such as the 20g-8, we are going to continue to work on it and try to make it even better.
I could have sat back and been extremely happy with the 20g the way it is but new in a better cover it would be even better. This is Evolution, get it?
The compressor cover pictured above is what I am testing next week. Rather than post and sell them immediately I am going to test it first and sell it later. Feel free to call and buy it direct, please! This will save me the money buying it and the time testing it! Let me know what you come up with, then I will go ahead and use it.
The cover pictured is a modified EVO8 cover. It was built to try to eliminate/reduce surging on the EVO8 turbos, of all types, not JUST the 20g. As I said, the absolute worste surge I have ever experienced in my life is with the normal TME, very violent, crazy.

To answer some ?'s yes I have a high boost actuator, yes I pressure test the IC pipes, and my compression is 175 across the board. I have adjusted the BOV and wastegate actuator. My setup now has the least amount of surge, but it is still present. I knew it surged some when I was going to buy it, but was under the impression that since I'm not a road racer it wouldn't affect me. How do I know that it spools 1000 rpm later? I simply look at my boost guage and tach (not rocket science) When stock I had full boost around 3200 rpms now I have full boost around 4200. I guess my expectations were set too high which is why I may have come off as unpleasant. I have nothing bad to say about Buschur and feel he does great things for the Evo community. Hopefully this new compressor cover will help things out and I will be doing meth/retune to hopefull crack 400 whp.
Turbo selction is a highly subjective process and is why its important to have forums like there to read about experiences.
I would say you should wait for some feed back on the new IX 20G - it looks most promising

I feel the IX 20G holds great promise - I liked and still like the other 20G that surged a bit
Interestingly - I have been tuning several White Rabbit turbos in the past two weeks and they also surge a bit
All of these upgraded turbos make at least 30 - 40 whp more than stock

first off, everyone are all hype up on the dyno number, who cares, i can't tune on a dyno, especially Dynojet. you havbe to tune on the street. You need to have load, and on the dyno there's no load. if you think your car is fast, take it to the track and see if your time have improve.
