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

George@GTM · 03-03-2008, 11:48 PM

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

Specs:
2008 Infiniti G37S Coupe

VQ37VHR w/ VVEL
Completely Stock Block
Blitz SBC Boost Controller
850cc Denso Injectors
Walbro 255 lph fuel pump
JWT FMU
HKS FCon VPro Standalone EMS
GReddy EVO TT exhaust
Innovate Dual LC-1 wideband feedback
GTM HR Prototype Twin Turbo System featuring:
-Dual Core, Bar & Plate Intercooler
-Twin Garret GT2861RS Water cooled Ball Bearing Turbos
-Twin 38mm TiAL external waste gates
-3" Down Pipes
-Mandrel Bent Stainless Steel turbo piping

8 PSI, 93 Octane

Overlay of stock power vs. stock block twin turbo power:

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.

A few pictures of the project:

Update: 3/4/2008 - New dyno video

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

carfi179 · 03-03-2008, 11:55 PM

Wow nice curve. Damn VHR stock block can hold that much ponies, just sick!

rcdash · 03-04-2008, 04:40 AM

Nice work guys - that torque curve to redline is just fantastic.

EDIT: Do you guys have a harness for the FCON Vpro for the new ECU already? And what is the "L*CON" sticker on the side of the car for

? Successor to the FCON?

RobbieG35 · 03-04-2008, 04:59 AM

Sick! Glad to finally see a stock motor that can take some power.

Jay'Z · 03-04-2008, 04:59 AM

Nice!! Very interesting to say the least..

doug · 03-04-2008, 06:18 AM

Is this the modified HKS TT Kit?

JAMEZ@CiNcity · 03-04-2008, 06:31 AM

Damn, thats some seriously nice numbers guys, keep up the good work.

GodSendsDeath · 03-04-2008, 06:36 AM

Hello there thanks for taking the time to post good stuff truly. My question is what is a VHR rod and a HR. I think HR is out of the Z, and my guess is that VHR is out of the G37? If so what do you guys expect the hr 350z to dyno on a stock block.

dutchboy · 03-04-2008, 06:49 AM
