GTM Performance Engineering: MHI Twin Turbo Official Release

I completely agree with you but in my case I was thinking of achieving 550 hp max until I can afford to build the internals. Would the longevity of the engine not be extended since your not running so much boost? The stress from the high hp will still be the same so I see what your saying

I'd be more worried about the torque, especially when those turbos start spinning, as it's a direct measurement of force applied on a given object, it is what breaks $hit

Took the words out of my mouth. And in the past, I've run a 50/50 water/meth mix on another vehicle. It allowed more timing, and another 3 psi of boost. It was a lot of fun, but I was always afraid of the meth kit failing in mid pull. I don't have a lot of faith that the failsafes would work fast enough to save the motor.

Seeing that and after riding in his car has made me a believer in going with the meth kit.

You need to put 2 nozzles in 1 in each intake pipe about 6in in front of the throttle body's but behind the MAF's.

So if one buys the GTR manifold you will need a nozzle for each cylinder?

For the trouble I had to go thru with the install ,tune , cost of Meth it wasn't worth the 30-35 rwhp you get

All you guys with these TT GTM kits will all be able to get over 500 rwhp it's enough anything more your just compensating for a small unit.

COSMO · 07-09-2013, 06:05 PM

Iam really not looking for more power but only to safe-guard the stock block....

If you want safe tell your tuner to dial back on the timing and keep the rwhp to 450-500.

Dzel · 07-09-2013, 06:37 PM

525-550 here but I drive my car maybe 6 times a year. Hopefully the block will hold till I'm ready good internal upgrades

6 times a year???? That will certainly change when you go boost.

Dzel · 07-09-2013, 07:34 PM

Lol probably will I haven't even gotten my hands on the kit and I already have like 4 boost your shirts. Favorite one is my keep calm and boost on shirt

I have never liked meth for that reason i.e. the worry about it failing at the wrong time. I had a kit on my STi that immediately had issues and after that I was just like, nah. It's too many additional points of failure and it requires a completely new tune since meth is a fuel and jacks with the ratios. I would be more inclined to run straight water injection to manage temps and run a bit leaner on the fuel side.

Chuck33079 · 07-09-2013, 08:16 PM

I never had a problem, and the power was nice. I just never felt comfortable with it. I don't trust the failsafes to shut it down to waste gate boost in time to save the motor.

COSMO · 07-09-2013, 10:30 PM

To each his own but already knowing what the stock block can handle I feel it wouldn't be a bad investment if even if I decided on not tapping each port and just tapping the intakes....

Chuck33079 · 07-09-2013, 10:37 PM

It's not bad if you just use the additional octane for detonation resistance, and some water to cool everything down. It's when you lean it out and add timing with an aggressive meth tune you start playing with fire.
