First of all I'm a huge fan of this WR and 21g in concept. As results trickle in on the WR it's looking better and better. As this generation of stockish turbos matures it is looking like a business oportunity that cannot be passed up on. Give Bushur a chance, especially in light of the FP results, I am sure there will be an answer.

 

I've been a fan of a "upgraded" OE turbo since day one... It will be interesting to see David's results indeed.

One thing I'd like to point out though... It seems the WR equivalent of this turbo is only $10 cheaper... so I don't see why people are trying to use the "price" as a comparison.

 

Our price will end up being much cheaper when they are finished. I have already discussed it with the builder and as we posted our pricing way back it seems as though pricing has been set so they are comparable. That will change on our end.

Here is the deal and I am glad someone started this topic.

I dyno'd 2-3 different CNC'd wheels and posted the results, none of which I was happy with. We then finally got a wheel cast and machined. By then we were no longer able to dyno the car (2wd dyno, car was back to AWD preparing for the Car and Driver event). I put the turbo on the car and went to the racetrack with it. The compressor surge was pretty severe with this turbo. The power was there though. My car with the stock turbo made 393 whp with the turbo spiking as high as 25 psi and falling off. With this surging version of the 21g on the car (only surged under part throttle) the car picked up 2.1 mph, which is just over 20 whp, bringing the estimated power up to 415 or so to the wheels. NOW, the difference was the turbo NEVER was over 21 psi. Had I let it go to 25 psi spikes the power/speed would have been better. Problem is running a turbo that will sustain 25 psi on pump gas is tough, the results would have been no good to any customer.

I was pretty pumped about the results but being the person I am would not sell a turbo that surged. I sent the turbo back and it was clipped. The turbo came back, we installed the turbo and ran the car again. Once again the boost was ran lower than the stock turbo would spike to. Results at the track (extremely hot the day we tested) were the same as I was seeing with the stock turbo.

I then sent back the turbo again (I thought I did). I called last week to ask why it was taking so long to get it back with the changes I ask to be made. I was told it was never received. I go back and look and sure enough there it sits on my work bench. I am an idiot. Send it back and was suppose to have it returned this week. Honestly with the C&D event I didn't even look to see if it came.

The turbo honestly looks very promising. I think this last change will produce results that I am happy with.

The sad part of this turbo project is I feel I have taken some serious beatings from some people for doing it. Had I not been honest in my testing and let everyone know all the things we have tried I wouldn't have to hear the crap I am getting now. Oh well, in the end it will work or it won't and if it does you will all know the work and time we put into it.

I don't need the money bad enough to lie and cheat anyone out of it. (I am in no way saying the WR doesn't work as I am sure it does) I'll sell our turbo when it performs well enough at a realistic boost level that results can be seen with any combination of parts.

I dont think there should be one person who gives you a hard time about your R&D being so open and HONEST.

There are no claims " this part makes 20 hp!!!! ....... i mean on c16 and 25psi" its all honest DYNO tested numbers I more than appreciate how open you are about your testing.

I am like a lot of people who follow your threads if the turbo makes the power i am looking for it i have a cash with your name on it.

 

you're a good man, david. we all appreciate your honesty and look forward to the results of your 21G.

quick question.. i don't know if this makes a difference or not, but would the changes in the IX turbo be a better place to start rather than the '05 VIII turbo if you're looking for maximum results?

It's really too bad that some of the people have only looked at the negative side of your turbo project. They can't comprehend that there can be alot of trial and error involved in order to make a product succesfull. I guess it's that instant gratifiaction mentality. David I wish you the best of luck on your 21G turbo project. Has anybody ever thought that the White Rabbit probably had to go through it's motions before Forced Performance was satisfied with their results. David at least kept us updated on his progress, whether it was good or bad.

 

Thanks guys, appreciate the good words.

Actually the EVO IX compressor housing is going to open an entire new world I think. That compressor housing looks like it is going to be a really good part to work with. The cost of it is going to be tough on us and so is the availability for awhile. I think you are correct though, the size of it is going to be an improvement. Hell, just bolting it on right from Mitsubishi might be the hot ticket.

I'm hope the best for this project, David. Good luck on your last changes to the turbo.

 

Well between FP and BR both are doing the turbo in their own way. I'm not sure on how long dave has been working on this but FP claims 2 years. It's all a matter of a little tweak here and there, then back and re-tune the car. All of this is very time consuming but Im sure there will be great results.

When Dave finally unveils his turbo there is going to be fierce competition between these 2 shops, i can't wait for those threads to show up. I can see some people getting a short term ban from these products.
