David Buschur's switch to the "big" turbo....
Well as I posted in the General thread we have been doing some testing and such finding more and more power the last few weeks. Daniel, my brother, just made 642 whp and 459 ft lbs of torque with his daily driver, on our dyno of course. His car ran 10.8 at 131 with about 470 whp on pump/alky, so it is going to be FAST now.
So anyhow. My RS, has been running very good with our EVO9-20g-5 turbo on it. A best of 11.11 at 124 mph was run with that turbo. The car is fully built and I have said it was just a turbo swap from being very fast. The car with the 20g-5 on it was an absolute blast to drive. Instant spool up, good runs at the track.
We have a new turbo that is going to be released very soon, sometime this month I hope. Please do not ask me about it as I will not answer the questions.
This new turbo was on my car and ran a 10.89 at 128 mph with this turbo. This is the best turbo I have ever had in 18 years. It is a joy to drive, silky smooth, fast spooling and still makes enough power to run 10's. I had to send the turbo back in to have some changes made, to hopefully make it better.
It was at this time I decided to install one of our normal GT35R turbo kits on the car. I was not happy with the car to be honest. Spools to slow, no low end. Can't accelerate from 35 mph in 5th gear without downshifting, just not a fun daily driver as far as I am concerned. I actually parked the car and drove my truck.
I put the car back on the dyno after finishing my brothers car to try and make more power. Well I did. The RS ended up making 572 whp and 459 ft lbs of torque. This is on C16 at 38 psi of boost. Very happy with the results and power level of the car. This is with our cast manifold and the special FP turbine housing kit we use. Al's car with a header/T3 housing made 580 whp with the boost as high as he could run it on our dyno. Curt's car is a freak, as we all know, and I was able to get 650 whp from his, which is just unbelievable and no other combination has been close to that. Al's is the highest "normal person" GT35R I have had on there before this.
I'd like to also input here that I have tested lighter brakes and such on the dyno to show it increases WHP and that my car has stock big brakes on it with Giro discs and an Exedy clutch in it.
Well driving the car hasn't changed my mind much about the turbo I want on it but that 572 whp does feel good driving back and forth to home. I am going to run the car on the Neova's and see what kind of times it will turn with out GT35R on it. After I get a respectable time from the car I am putting the small turbo back on it to finish up the testing. I think the car will run 10.50's with the new turbo on it and will remain stock appearing. We will see.
Anyone interested in dyno sheets say the word and I will post a graph tomorrow of the new "20g" vs. the GT35R that is on it now.
Going to the Outback to eat. Later guys.

Definately want to see graphs comparing the two and your regular 20G if you have them. Tells us more about the new turbo, j/k.

Yes Dave post the graphs. It is very interesting to see how you are able to extract so much hp from the small "20G". My EVO doesn't even have 4K miles, but next year when I start modding, one of your "20G's" is what I am looking to get.
