This car came in completely stock (minus the wheels). We installed our GTM G37 Complete Turn-Key Twin Turbo System, along with a few other supporting mods and this car is making awesome power at only 5 PSI!
The new VVEL engines are truly amazing, although difficult to tune for the inexperienced, they flow so much more air than the previous engines, which makes them an awesome power house.
We are not yet done with the tuning on this car, these are only preliminary numbers on waste gate pressure, keep in mind this car is an automatic as well so the drive train loss will be higher than if it was a 6MT.
Hopefully we will have some new graphs shortly with a nice increase in power output
The factory brace is removed in place of the intercooler, and the intercooler bolts to the factory brace mounting points via its 1/2" aluminum brackets,
Beautifully done! Congrats. GT2860RS w/ .86AR at 5 psi = 450 hp?!?!! Amazing peak power levels at such low boost.
EDIT: Is this valvebody on a 7AT?
Hey Raj, as you can see the torque number is still fairly low, the reason the HP number is so high is due to the efficiency of the VVEL system, that with the better flowing heads.
This is going to be THE platform to modify IMO.
Let's see how she reacts to more boost in the days to come
Also, the low torque output is going to place much less stress on the rods, so you can imagine how much more reliable this engine will be opposed to our engines (stock for stock that is)

This is why it is not pictured above.

Oh wow, I didn't realize how big the brackets were. Looks good.

Ridiculously flat torque curve. And I just noticed the date / time stamp on the dyno chart - 11:20 at night, west coast time.
