The Titanium-Aluminide turbine wheel from the TME 6.5 turbo is an optional component of the White Rabbit and not considered standard.. Just thought you'd like to know It saves about 200 rpm's. to spool quicker..

 

Well my goal is to get about 450 whp from this turbo is that possible or is it pusing the limits of the turbo?

 

put it this way, someone hit 10's on this turbo.

someone on these forums hit 450 with full bolt-ons, flash, meth injection.

while his car might be the exception rather than the example, there are numerous examples of this turbo getting between 400-450.

 

I have done some research and their are some facotry turbo Evos with 400-450 whp. I am currently running a facotry Evo 8 turbo with the 9.8 hotside would I see kinda similar gains if I just went with a Evo 9 turbo with the 10.5 hotside and a aftermarket 02 housing (already have just not installed)

 

The White Rabbit and Green are different, and the Green is vastly superior. It makes more power and spool up is very similar.

This is the first time I've heard of standard vs. non-standard versions of the White Rabbit being offered by Forced Performance. Maybe you're thinking of a different variety of long-eared, hopping lagomorph, such as the closely related hare. Rabbits are characterized by being smaller than the hares and are blind and furless at birth.

AFAIK, the rotating assembly for all variations of the FP WR still consists of Forced Performance's proprietary, billet aluminum, machined 20G-5 blade compressor wheel mated to the titanium aluminide Mitsubishi "TME" low rotational mass turbine wheel.

In fact the titanium aluminide turbine wheel is what differentiates the WR from its sibling within the Forced Performance lineup, the BR 20G-9-5. The Buschur Racing 20G-9-5, does share the same compressor wheel with the WR, however instead of a TiAl turbine, it is configured with the same inconel turbine wheel found in most other Mitsubishi 16G configurations.

Actually, Forced Performance could have opted for the other TiAl turbine wheel, which is the RS TiAl wheel found in JDM Evo VIII RS turbos. It is a bit larger and ultimately a lower backpressure design than the garden variety TME turbine wheel.

 

Stock turboed Evos with standard bolt-ons, producing over 400WHP on a dyno are rare I think. 450 WHP from the standard turbo seems pretty unlikely although maybe someone has done it. I don't remember what these guys like C.B. and Scott from TTP dyno their cars at, but they both have run some pretty fantastic trap speeds, well over 125 mph, with the stock turbo.

I just don't think there are many examples of street Evos putting out much over 400 WHP on the stock 16G. I guess it would depend on the dyno though. I think that apart from the two I mentioned above, you could count them on one hand.

 

stock turbos at 400+ awhp probably aren't running pump gas either and have every mod possible to do it. also how light are those cars? all factors to keep in mind so you aren't comparing apples to oranges.

 

Thanks for everyones input so I guess the last questions is should I look into a WR-9 or try and save for a Green turbo? I know a guy that was running a WR-9 and hes selling it for a reasonable price so should I jump on it or hold my guns for awhile?

 

Green

 

The WR-9 is capable of torque at least as good, if not better than the Green on pumpgas. The horsepower comparison has to be real close as well, if you think about it, because they both use identical compressor wheels and compressor housings. The rated flow of the compressor should ultimately determine the power potential of a turbo, and they do both share the same compressor side.

Any power advantage which the Green may have, could only be due to the lower back pressure, albeit higher inertia turbine wheel. There is a tradeoff in lowend torque and spoolup though. The WR-9 should exhibit improved spoolup and midrange torque as well as better transient response due to the titanium aluminide composition of the TME turbine wheel.

So, how much is your friend asking for the used WR-9? The WR might have more of a tendency toward compressor surge than the Green. So, you'll wanna make sure that the seals are in good shape and that there is minimal back and forth(axial)shaft play.

If you really value spoolup and street response. That is, if it's a daily driver on pumpgas, then I'd consider the WR-9 over the Green. If you're gonna be cranking up the boost to 30# on race gas or alkie at the track, then I'd opt for the Green.

 

wasn't surge one of the main problems with frankenstiening the TME turbine?
did they fix or figure something out??? or does the 9 compressor housing help??

i would get some more input or be the one to post it.

go buy it so i dont have to!!!

 

I could'nt have explained it any better. Well put!!!!

 

You are correct the TME had issues with surging. The Evo 9 compressor housing eliminated surging issues with the stock 16G that came on the 8. I don't beleive the WR-9 would have issues with surging because of the 9 compressor housing and I also believe the compressor wheel is clipped but I could be wrong.

 

Whats up guys I want to thank everyone for their input and I have decided to go with the WR-9 turbo. I can get all these parts for a good deal that I cant pass up at all. My last question is do I need a AEM EMS system for this? I got a EMS system brand new for a excellent price so I moved on it asap and im just wondering would I need it for this application. I know the big guys running the GT series turbo would benefit from it alot but since im running only a slightly bigger turbo would I need it or could my car be tuned pretty good through the dyno and laptop (flash)? I know ill get some gains from a EMS but would it be enough to keep it or sell it and make the profit?
