GTM Performance Engineering: MHI Twin Turbo Official Release

Mike@GTM

For a track car, heat is the biggest concern. There are a number of ways you can attack the problem. Things like a vented hood, upgraded fans, using Uprev to lower the temperature the fans come on at, upgraded radiator. Those are the "off the shelf" options. Of course, there are a variety of other things you can do depending on how creative or resourceful you are.

Before you start getting crazy with the cooling mods though, it would be a good idea to get a firm grip on where you are now with your coolant and oil temps. While gauges can go a long way to helping you determine that, you want to be focused on your driving as opposed to your gauges. Therefore, it would be ideal to have data logging capability so you can go over the logs while you're in the paddock after your session to see your peak temps.

Just remember that different tracks will have different demands on the car and the driver. Some tracks are going to push your cooling system hard while others are going to shred your tires instead. You need to setup your car for what you are trying to do, the track you are driving on and the conditions you are driving in.

As always, powder coated intercooler pipes and thermal dispersant coating on the intercooler are optional.

As for specifying different blow off valves or other components, keep in mind that the intent of this kit is to have it on the shelf and ready to ship. While we can certainly accommodate custom orders, it will add to the lead time.

Thank you.

The need to change turbos depends on which setup you start out with. If you go with the 18g's, you won't need to change turbos for more power. The dyno graph on the Mustang dyno was with the 18g's on the stock engine and 91 octane gas.

Yes, we can send you a base map to get you going if you get the tuner kit.

As for production, we are still ironing out some details on production time. Once we have the information on when these kits will be available, we will announce it.
