Thanks for the info Im just wondering if the heat exchanger could be even better? How do you have the tune setup to pull timing when IATS go up?

The heat exchanger we are currently using is very efficient and works as designed. As the chart posted above noted we are seeing very minor gains in IAT's with 5-6 psi of boost. Our software is designed to correctly adjust timing when IAT temps require it.

So good weather and some real tires will put this in the game with some top dogs on that list
Can't wait to get my system in Roman. Any way I could get a Gloss Black ESS badge for my trunk |

In your graph above, we are seeing telltale creep of intake air temperatures which indicates the heat exchanging capability of the intercooling system is reaching saturation. This is a common issue with air-to-water intercoolers - although they do a great job whilst the system is not saturated, once the system can no longer sink heat from the charge because the water cooling system is saturated with heat (because the heat exchanger can't cycle out heat to the atmosphere quickly enough), intake air temperatures start rising pretty rapidly. I certainly wouldn't risk my car on a track for more than 5 minutes, even with safe levels of timing and tuning it rich, I think EGTs would become a problem with much more track time. Granted when you are making 600HP you have significantly greater air mass to cool than my example (~33% more air mass) so I sympathize with anybody designing an intercooling system for this setup... I'd be more comfortable with a properly matched air-to-air intercooler system although real estate at the front of the car becomes an issue here, and you add weight where you want it the least.... |

Air-to-air is a more direct method of intercooling, basically the heat that is sunk into the intercooler is removed back into the air immediately. The intercoolers are bigger and heavier because air is not as effective at cooling than water, but they do work when they are properly sized and sourced from a reputable manufacturer.
Air-to-water has a more instantaneous cooling effect, because water absorbs heat more effectively than air, but it transfers absorbed heat to the heat exchanger, where heat is then removed to the atmosphere (i.e. air becomes the ultimate limiting factor as to how fast heat can be removed). Most of the heat exchangers you see are much smaller than air-to-air intercoolers, hence if you are continuously generating large amounts of heat (e.g. extended hard driving), the system eventually runs out of heat capacity and cooling diminishes... General rule of thumb is air-to-water works great for the drag strip and normal daily driving, air-to-air is better for the track... |

Any pics of the cooling system and how it is mounted?
I'm guessing its on the underpanel and attached right below the radiator passing the lines to the side of the airbox, oh and about that badge lol |

The gt500 uses air to water and we like to keep iat's below 120. Trust me we put down 1000hp and 900 trq to the wheels and the the air to water works well.

Rom3n,
Can you summarize the $8995 kit? What's included and the expected hp? Tried to PM but your box is full. Thx, BC
