I've been able to secure some upgraded compressor wheels for the GT15 turbos used on 3.5L transverse (SHO/Flex/MKT/MKS/Explorer Sport).
These compressor wheels allow you to get an additional 2-3 psi down low and hold to 19 psi on the top end of the RPM range.
I tested these on my Flex and ran 12.3 at very high DA.
Usually I sell this as a mail your turbo in option but I can now source the wheels for you to do the upgrade yourself.


As an introductory special I will offer these at $100 off - $500 for the first 30 days.

I also have Turbosmart 7PSI Wastegates to allow for better boost control with the larger compressor wheels available here:

These are in stock and ready to ship!













 
Nice!  Is this a DIY task or best left to a pro?  This would make a nice addition to the HOW TO section ;)
 
It looks like the stocker has a slot cut into it at the top that I don't see on the billet unit.

Does that affect anything?
 
Ok...  You have peaked my interest on the impeller.  But I'm curious about the wastegate. Since the stock is only 4psi.  Will this need to be changed as well??  Cause if I remember right they were upgraded to 7psi ones on your upgraded turbo option....  And at 19psi are the turbos maxed out with the new blades or are they running at a safe psi where they will last?  Thanks
 
I'm checking into supplying the wastegate as an option.
I would suggest a tune update as with the additional boost you will probably hit torque limiters.
 
So 2-3 more down low, does response time change, will there be any more lag?

With this change will the turbos be inside of their efficiency range at 19PSI?

OT question....how in the hell was the refresh rate so fast on that Torque setup?

I'm on an OBDMX with a powerful quad core tab and I can't get it to refresh that fast.
 
I have seen ForScan pull 27 ms refreshes with the Bluetooth MX.  Can't go below 100 ms with Torque Pro, so no comment on that.  Using the original Nexus 7.  And yes, I am polling 25-30 parameters at any given time.

Will this upgrade need to be balanced with the turbine wheel?

No as I'm just shipping you a compressor wheel - if you want it balanced it will be $1600 installed, send your turbos in and they will be installed, balanced and all seals upgraded, turbos rebuilt.

Can you supply compressor maps for the stock vs. new impeller?

Unfortunately no, but I can tell you that I picked up a TON of power from this upgrade.

I'll make it easier, first person that purchases them, does a before and after dyno on the same dyno and submits the results online (good or bad) I will refund $250.00 to them.
It's a chance you'll take but I know that these work as witnessed by the results I saw on my car, I picked up well over .7 from these on my car with E85 as compared to stock turbos with 100 octane tune. I picked up .1 over nitrous and 100 octane on my car with stock turbos. I know they work.
 
Probably stupid questions but....  Will they even need to be balanced once installed?  And they would be fine on the stock wastegate?  Also, you said it made a lot more power. How much boost did you add once you switched to the upgraded turbos vs the stock turbos to make your power?  I'm just curious cause I am on the fence about doing this deal. And I haven't really researched how hard it is to pull the turbos. I imagine not to bad.  Thanks.  Jason
 
From my understanding if the turbo is super old yes, but newer turbos you should be fine (key word should). I would think on stock wastegate you be just fine, waiting for pricing on the other ones.
I was seeing 21psi down low and 19psi up top vs 19 to 14 psi on stock turbos.
Front turbo is piece of cake, back one is a puzzle to rotate to get out.
