GTM Performance Engineering: MHI Twin Turbo Official Release

zguynate

This pretty amazing. That price is ridiculous. It will be between this and the Boosted Performance kit for me. Good job GTM!

Just like Big T im getting married in Sept. My fiance would kill me if I bought ANYTHING for the car before the wedding, let alone a turbo kit lol. Its looking like it will be the beginning of next year for me.

I got married about 10 months ago. She knew what she was getting into. I told her I was going to buy this kit and she gave me a hard time but finally gave me a "whatever", thats good enough for me

Now the question is, I am mechanicly inclined and have a decent tool set, not a full set of everything by any means. Can I install this myself on jack stands with the engine in? Hrm... Thoughts?

Lol it can be done with the engine in. Makes for one of the most enjoyable experiences you'll have with the car. Please update us!

I could technically walk to work everyday. 15 mile trip. I could walk it. But why walk when I can drive comfortably.

I dont have air tools and more advanced mechanics gear. I have all sockets and wrenches.. all the hand tools you could ask for. I do have an air compressor.. Will I need to buy some tools in addition to what I have? I am ready to tackle this project!

U could do it. Jus have patience, beer and more patience. You'll need to take breaks and know when to walk away n try again later.

Whats the window's on all the different Tiers for the group buys?

Mike@GTM

Yes, there is a difference in spool between the three turbo options. With bigger turbos, you make more power at the expense of responsiveness.

This kit was designed from the outset to be very appropriate for the stock engine. Our Turn-Key kits are supplied specifically for installation on a stock engine.

One thing I'd like to mention is that you really want to keep the engine stock since it is the most reliable setup you can get. Purchasing a turbo kit that is designed to run on the stock engine is really the best forced induction decision you can make. 500whp is no joke on these cars and the fact that the stock engine can sustain that level of power for a very long time (60k+) is what is this kit is all about.

In regards to what boost the Turn-Key map is setup for, you need to remember that this is a Blow Through MAF setup. That basically means that it has more to do with mass airflow than boost pressure. Even then, the limiting factor is the factory return-less fuel system. That said, you don't really need to upgrade to a return fuel system until you are making more power than the stock engine can handle in the first place. So, basically, what I'm saying is that our Turn-Key kit with our tune can take you to the limit of what the engine can handle reliably and a little further. So far, that translates to roughly 11 - 12psi of boost.

We are still working out the details for the group buy and will be posting that along with more information on the financing options.

I'm actually still working on the installation manual between answering e-mails, pm's and forum posts. It should be all wrapped up before the kit starts shipping though.

We think that the price is really only part of what will help this kit sell. It's more about the performance/$ that really drives home the value of this kit. It performs extremely well compared to other options and costs substantially less as well. That, is value.

It should take roughly 25 hours for a competent technician to install this kit. Based on your local labor rate, that should give you a good idea of how much it is going to cost you to get it installed if you decide against tackling the install yourself.

The need for a clutch upgrade really depends on the health of your stock clutch. If it's hammered pretty hard, it won't last long and you should budget for an upgrade. Otherwise, if you have relatively low mileage on it, it shouldn't be an issue.

As for your numbers, I'm not following your math on that since we've given pretty good indicators on how much it should realistically run. $6k for the Tier 1 into pricing on the Turn-Key kit (no tuning required) + (25 hours * $/hour of shop labor rate) = installed cost.

As for the government, it's not an issue. I know it seems so good that it must be illegal, but there's nothing wrong with financing a turbo kit or sound system, house, car, or whatever else you care to finance. lol

^^^ you can finance mattresses. Them Tempurpedic's can get expensive.

Dyno sheets from the 18g setup yet? I'd like to see the powercurve.

Here you go:


As you can see, the 18g's are sized very well and have great area under the curve. This is a very responsive system with great top-end performance.

How much power did that top graph get? 11psi on 91octance should be 550whp+?

These new graphs are of the mustang dyno correct?
