GTM Performance Engineering: GTM TD05 16G Test Results 91 Octane 7AT
We are excited to present the initial testing results of our newly developed TD05 Twin Turbo Kit. The example we are sharing with you today is our 16G Kit installed on a brand new 2012 Infiniti IPL G37 Coupe with the 7 speed automatic. The car was brought to us bone stock and gave us a great opportunity to test several scenarios so people can get a realistic idea of how this kit will perform depending on their combination of supporting modifications. All testing was performed using California 91 octane pump gas and 10 psi of boost.
The only other modifications we did to this car are our GTM Engine Oil Cooler, GTM Automatic Transmission Cooler, and our new GTM Valve Body Upgrade for the 7 speed automatic transmission. This enables people who choose the convenience of the automatic transmission to have their cake and eat it too: big power and no headaches. We’ll be sharing more on this later.
Overall, we’re extremely happy with the way the kit performs. On the street, with stock cats and stock exhaust, we were seeing 4psi at 2200rpm without even trying. The car ultimately performs like a factory turbocharged car with quick response, ultra smooth power delivery and exceptional drivability. Keeping the stock exhaust gives the car a silent but deadly attitude as the tach sweeps through the power band while slingshotting away from a stop.
For starters, our new kit is designed to retain the factory crash bar, can accommodate both manual and automatic transmissions as well as any aftermarket or stock exhaust system preferred by the end user. Here are some pictures of the kit and the baseline dyno run.
For the emissions conscious enthusiast, we tested our new TD05 Twin Turbo Kit with the stock cats and cat-back exhaust. Despite the restriction, the kit still delivers 440whp and 422wtq on 91 octane pump gas at 10psi of boost with an automatic as seen in the dyno graph below. As you can see, the restrictive stock exhaust causes torque to plummet at high rpm. Despite this being an IPL with the higher flowing exhaust, it is still far too restrictive for a forced induction car.
Opening up the exhaust with a set of test pipes still keeps an understated exhaust note while delivering more power and torque at higher rpm as you can see in the dyno graph below. As you can see, torque doesn't fall off quite as hard at high rpm with test pipes. That said, there's still room for improvement in the exhaust department.
For best results, a less restrictive exhaust is a better way to go. Shown below are the results of our test pipes and no mufflers; still at 10psi on 91 octane with an automatic transmission. As you can see, torque stays flat all the way to redline once the exhaust is opened up.

THANK YOU! This beast goes! Sam did a beautiful job on this build. Driving it is a joy and damn can this beast smoke the tires for ages.
The kick when the gas peddle is burried into the floor is insane.
New exhaust will have me topping 500! And on a reliable daily driver. I couldn't be happier.

Wow!! You just made my day Sam!
Will the stock cats hold up with this setup? Interesting how the highest low-end tq figures were achieved with the stock exhaust

man I can't wait to see the price. It should be a good amount cheaper, the turbos should be better priced than the ball bearing turbos used in their other kits. Also the TDO5 turbos they are used are internal wastegated so that should knock off almost 600 in Tial wastegate costs
Another excited product put out my GTM it seems 2012 is gonna be an awesome year for G37s

I am very interested as well for more information that hopefully will be updated on this thread soon by Sam... This kit seems to have come out of nowhere which is nice as I hate knowing of a kit and waiting and waiting to see why the final product is... it builds too many un-needed expectation IMO.
But this is very interesting... Cost point will be the make or breaker I assume.
Let us know Sam... PM me if need be on the cost.
Again, thank you so much for all that you have brought our community... I feel taht is not mentioned enough!
