Just thought every once in while we would post up some of the latest on whats upcoming in the world of Turbo Technology.

What's pictured below is the newest set of wheels we plan to introduce into the performance market. They will flow significantly more air then the Garrett GT wheels.

First picture: Left is new wheel (01), right is GT40 wheel. As you can see the left wheel has a MUCH more aggressive cut and pitch.




Second Picture: Left wheel is once again GT40, right wheel is new wheel(02). As you can see this wheel is even more aggressive then the (01) and will flow alot more air then the GT40 as well.




In testing (5.9L), the GT40 would hold 30psi max before the compressor went into the choke limit. The (01) wheel will hold 57psi strong. We have not tested the new (02) wheel yet, but figure with the new impeller design and exducer wheel pitch it should hold 60+psi . In terms of Horsepower, the new 01 and 02 wheels should make more then 100rwhp over the current GT40 wheel.


(01) wheel left, GT40 wheel right.



GT40 wheel left, (02) wheel right.

BTW, the impellers are all the same MM size. Also the 01 and 02 wheel are lighter then the GT40.

 

Impressive.

 

That is pretty damn cool. Some thing that confuses me on teh first 2 pics though. You say teh 01 is better then teh GT40 and the 02 is better then the 01, BUT the 01 looks like it is alot bigger then the GT40 adn the 02 looks liek it is the same size as the GT40. Why is that? I know that bigger isnt always better but it seems liek it should be in this situation. Thanks

Well actually it was more the angle at which we took the picture. In reality they are all the same basic size. Funny how just a slight angle difference in the picture can make things look way different....lol.

Jose

 

So the 02 01 and hte GT40 are all teh same height? That is a neat optical illusion ya got there lol. GL


John

 

so what does this mean to those of us that are not super turbo savvy?

can I take a wheel out of my gt67 from my sts for example and pop one of these in and achieve better spool / top end or does it not work that way?

 

Yes the 01 and 02 wheel are both a touch taller then the GT40, which we machine the housing for that. The I/E are all the same though.

Jose

 

Heath these are the compressor wheels, which combined with your current exhaust wheel will probably spool a touch quicker, but not something you would notice. We are working on the turbine wheels also, which combined together should make the STS units more responsive and still be able to move ALOT more air. For the front mount guys, that means fast spool and still be able to hold it till redline.

Jose

 

ahh ok, so down the road if/when my turbo needs a rebuild these would be components I would want to consider to get a little more bang for my buck?

I assume a rebuild with these components would be much less expensive than just switching to a different turbo.

 

Yes it will be cheaper much then a new turbo, and it will be fully re-balanced.

Jose

 

Jose can I send my 106 in for one of those "upgrades"

 

Nice, keeping us updated with the latest turbo tech Now this is a great resource to have and keep around. Thank Jose....so what'll it do for my GT42?? Got a wheel for that

 

LOL, actually we have found larger newer style wheels then the current 106's.

 

for not knowing what i'm looking at i'd say that the new ones look great!

p.s. you get word from precision on the ETA?.

 

Sure do....actually we are looking at offering a super 76 version, 78mm version, 82mm, 85mm, and a Super 88mm. Now I say that, but we have to check all the clearences and make sure we can machine the housings enough for them. Some housings just don't have enough meat to fit larger wheels, and some do.

Jose

 

I pulled one for you that has an On-center housing, going to get PTE to send me the correct housing. Much quicker then waiting. I'll replace the current ones I'm sending with the ones I have on order. Works better, less wait time, plus I want to make sure you make the events...lol.

Jose

 

cool, dont forget the other goodies with it. i'll need all my duck in a row to get installed in time.

 

jose if someone is going for 700-800ish, is this kind of wheel going to make much of a difference in a t-76GTS???

How much is the upgrade going to cost approx?
Thanks

The wheels we are going to use will be tested againist these other current Garrett units. Until then I can not say what the mid boost flow will look like. I can say these new wheels are going to bring a whole new level of power for the T4 class units. I dare say the 76mm wheel we plan to use should flow another 50-100hp more. Cost I don't know yet, since we haven't completed the machining costs yet, plus wheels. But I will say it will be MUCH cheaper then buying a new turbo.
