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 along with milk and freshly baked goods. 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. http://i313.photobucket.com/albums/l...S/P1200397.jpg http://i313.photobucket.com/albums/l...G/P1200170.jpg http://i313.photobucket.com/albums/l...G/P1200483.jpg http://i313.photobucket.com/albums/l...G/P1200536.jpg http://i313.photobucket.com/albums/l...G/P1200554.jpg http://i313.photobucket.com/albums/l...G/P1200556.jpg http://i313.photobucket.com/albums/l.../Baseline1.jpg 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. |
whoa! More info on the 7at valve body upgrade please!
|
WOW,, Impressive..
|
This kit looks awesome! Any plan on doing a comparison between the TD05 kit and the Garret kit (Stage II)? They look like they make similar power.
You guys are coming out with so much stuff I cannot eve decide what I want more. |
Taking out The stock cats free up that much power? That's wild
|
Haha I like the baking joke to that's funny
|
What's the price going to be on this ??
|
Very impressive, when do i sign?

Glad to see someone with 7AT getting the power they paid for and the clean install. Very nice. Maybe one day a certain company, not naming names or anything, will figure out how to tune a 7AT. Very nice work GTM. I now know who to goto next time.

Great results. Was there more tuning or more smoothing on the bottom graph? The curves appear to be WAY smoother. Also, it's interesting that the WTQ drops fairly dramatically between the all stock exhaust setup and the TP setup. Again, is this a tuning issue (i.e. not optimized for this setup)? Would also be really nice to see the boost curves on those dynos. Love the looks of that last dyno.
|
I love the sleeper look and would like to know the price on the kit plus the extras. "GTM Engine Oil Cooler, GTM Automatic Transmission Cooler, and our new GTM Valve Body Upgrade for the 7 speed automatic transmission."
|
Soo who do I gotta call to get all this now lol I want TT so bad but have been scared cuz I have a 7AT. I think I will be calling u soon
|
Also I'd probably get higher numbers since in PA we have 93 octane and it's all I run in my car :)

There's no way I can afford FI right now, but this is a sick kit, and I love the stock look. Nice work!

Great results!

I glad to here that the VB is now tested and working,. please get my VB done and installed in my fully modified 7 AT, that is waiting for it to be completed.
Very nice #'s for the turbo kit Z |
Interested in the VB upgrade but I'm lactose intolerant.
|
I know maybe a dumb question , But whats the biggest difference in doing the upgraded VB, and just having the TQ tables changed VIA UPREV? Thanx and sorry if it's a NUMB question LOL
|
The vb will let the tranney shift faster and harder and hold more rwhp with less damage to the tranney.

Ah ok thanx man. Like the first thing my tuner said was NEVER floor it in 5-7. LOL but if I'm shifting like Hwy pulls I should shift out of 4th at wot? So basically go no faster than 130. ;) |

I've got 496rwhp on meth and I haven't had any issues at all with my trans including alott of dyno time. |

Not without upgrading your tranny, 5-7's clutches can't handle the extra torque. |
