Exclamation GT Motorsports: G37S VHRTT, GTM HR Turbo Kit, FCon VPro, Stock Block Testing

With much anticipation we have finally made some time to work on our GTM TT G37S. These are preliminary numbers at just 8 psi of boost, very impressed so far to say the least. We are making good power on the top end with a flat torque thanks to the VVEL, although it can be tricky to work with, we have overcome quite a few challenges (with the help of the CONSULT III) to keep the car happy and make everything work well together.

We will keep posting more updates as time permits, looks like you guys will be seeing a 600rwhp stock block GTM TT VQ37VHR pretty soon here

Rod Comparison, from left to right: HR Rod, VHR Rod, and DE rod. As you can see the VHR has the strongest rod, we have already made 568rwhp but had to stop due to a coupler popping off and boost controller issue. We feel this engine will take 600rwhp no problem.

Clutch Slipping:

Did some more tuning on the car today, we are currently at 549 rwhp with 502rwtq and the stock clutch started to slip, we were hoping to break the 600rwhp mark, so far the car has demonstrated awesome performance in all aspects, very stable, and very responsive to boost. All these runs and boost have not seemed to phase the car in any shape or form, we will confirm when we tear down the engine. Since the clutch will have to be replaced at this point, we are going to proceed to the second phase of testing (4.5L Stroked N/A high compression engine) we will see what we can get out of the engine in N/A form with no boost. After that we will test our 4.5L Stroked turbo car with twin Garret GT35R's and some other goodies

Good to see. Hopefully this mod won't take 6 months before it is released.
