Keep painting things black and it will look like a bumper car soon.

Very good looking car.

HP Logic, re the GTM TT install, is the car an automatic or manual? If manual, did you stay with the stock clutch?

it is a manual tranny, and we went with the JWT clutch and flywheel

i wanna see flames! out of the exhaust that is

Any feedback regarding how the turbos have impacted oil temperatures?

haven't really made a point of checking but we did add the Stillen oil cooler, I know on the dyno they were not an issue.

It really depends on how hard you drive it. If the oil temp creeps up, it will be due to the engine and not the turbos. If the motor is not in boost, oil temps stay down.

I have an HR motor and on my daily commute, the temp reading on my CAMP2 hits around 230 deg F in Southern CA. The commute speeds range from stop and go to "pretty fast"

The oil feed restrictor to the turbos are VERY small (thousandths of an inch). The oil feed is meant to lubricate the bearings in the turbo. Cooling for the turbos are taken care of by the engine coolant. FWIW, my coolant temps run between 180 and 200 degrees F.

Thank you Terry. Just the kind of response I was looking for. So really, the direct impact on the oil temperature from the turbos is minimal because a very small portion of motor oil is in contact with the bearings.

Do I have that right?

correct, terry's explanation was pretty good, the amount of oil is small when compared to the oil capacity of the engine.

cooler is always a good idea specially when considering the temps down here and also that you will probably be driving the car harder and also the engine reving a lot faster while in boost than when NA

On the way home from work, I took note of some peak holds which I haven't cleared since the beginning of this year. We've also had our share of 100+ weather. BUT ... I've never tracked my car so I've never hit limp mode.

EGT = 1453 at the manifold

Oil T = 233

Coolant T = 222

For reference at idle, the EGT goes down to 700-750.

So yea, the turbos will not add much more heat to the oil but under boost, the higher EGT WILL. If I tracked my car, I'd add an oil cooler.
