Anyone that has talked about getting this turbo actually got one and installed it yet?

I think last time I counted it was close to 100 of them in the field on trucks already. Seems most of my customers are not forum junkies so you don't see a lot on line about them. I did personally do a back to back comparison of this turbo versus a cast S468/83 .90 with no tuning changes and the 65mmvgt beat the S400 everywhere but peak hp, S468 made 11hp more but sucked it up in the torque department. For a 3mm larger compressor and a much larger turbine combination it sure didn't do anything impressive in my book.
The drive pressure was almost exactly the same except down low the S400 had less drive pressure but it also made less power which is why there is a big difference in lag! Numbers were 40psi boost and 60psi drive on the Cast 468-83 .90ar. Had to retune the tcm just to make it drive halfway decent by stretching the shift points out and making it down shift much sooner to get it to go. For a stock injector stock motor truck there is no reason to go to an S400 turbo when it doesn't do anything but make it a smokey laggy pig. I'll keep my vgt's!
Awesome!!
I need to revive that. That test could be very handy for the guys looking for street manners and choosing a turbo setup, I forgot about it myself.
I think I already did the test with my BMW GT3794va(Edit: I did it with one of my Billet 66mm Vgt's, the BMW GT3794va hits even faster than the one I did before) but I need to do it with the S468/83 .90ar. I will go back and verify that though.

IF you remember from your thread I did it with the normal open at idle to get the 2.5 second spool up time with the 66mmvgt. When I tried to squeeze them to go faster it just smoked the tires, lol! Need 4x4 for that test. The 3794 was faster than the 66mmvgt. The S468-83 will be half as fast if I'm lucky even with the tcm retuned. Might try it with both tcm tunes to see the difference if any.:thumb:
Would be very interesting to see both for sure. That's the benefit of the vanes, you can tweak them to get the results you are looking for. :thumb:
I've had this turbo for a few weeks now on stock fueling and this thing is amazing lights fast just like the stocker but pulls so much better! And it sounds amazing!
