Garrett VGT on a 12v

I installed a Garrett VGT off a 6.0 on my 12valve using a Fleece Performance TurboBrake as a controller. It took some time to tune it but we finally got it driving perfect. I doubled my boost and the truck accelerates much faster. Truck is a stock so i didn't have much to work with but its amazing the difference. The controller uses a turbo dutycycle table, boost vs rpm with a throttle position kicker for accels/deccels. It has two lookup tables so you can run different maps based on your driving. there is also a manual adjust so i can dial slightly more or less vane position (boost). Its amazing the difference on the freeway. 70mph and 3psi, 800degrees egt. Dial it to 8psi and it drops to 650degrees. Pinch it shut on the freeway and you can hear go into orbit. Release it instantly from 10psi and the sound it makes from decompressing is crazy.

This is very interesting.

Im just worried, I don't hear good things about the reliability of those turbos.


Nice work though.
 
I thought it was going to blow up on the freeway when i pinched it shut but so far so good.
 
Could the compressor housing be turned so it is in the right position? Then you wouldn't need that crazy pipe?
 
you can't remove the housing and reclock and i was told the bolts behind the wheel do not allow it to rotate either. i wanted a variable vane and it was this or the he351 and i got this charger first.

It can be clocked. 90 degrees at a time. The 4 bolts are behind the compressor wheel. Very cool
 
about a year or so ago..... i had this idea also.
But.. i could not figure out how i could change the voltage going to it to make the vanes move with boost.
around 10 volts is wide open and around 12 volts is all the way closed (smallest).
Good job figuring out.
I wanted to figure it all out and make it work decend because i thought that it would work AWESOME for a large twins setup.
The instant spoolup could be had by using the vgt. Put an 80 or 88 under it and it would work pretty dang good i think. The exhaust housing is very big when the vanes are wide open. This would eliminate the need for EX. gates and stuff like that.
Instant spoolup to get big charger going...... then large housing for good flow when the bottom charger does get going.
THE best of both worlds.

Nice, i wish i knew this 3 weeks ago.

Fleece has a controller for the HE351 as well but it does not have this nice user interface.

The vane positions run 40-55% closed most the time. My table goes to 30% around 3000 rpm and 30psi but i don't thinks its possible to get to there without more fuel.
 
the Fleece controller for the HE351 is the same one you're using!

it's the same one I've got on my custom Fleece VNT setup
 
Have you looked at your backpressure?

I know on the 6.0's these have pretty high back pressure and in a compound setup they start throwing parts. I'm curious if yours has the same issues or not.
