Roush heat soak

[Angrey]

I really appreciate your opinion. You definitely have good insight and I don't doubt your experience at all. We actually have a mount for our brick that puts it directly behind the crash bar for the Roush setup as their heat exchanger leaves enough room to mount it there. I have only had one customer ask about being able to shut off just the chiller refrigerant flow. That wouldn't be hard to do by just adding in another refrigerant valve between the T and the chiller on the liquid line but I think you would have to be careful not to shut both valves off at the same time. Not confident the ac pressure switch would read this properly and shut the compressor off if that was done on accident to prevent it from popping the pressure relief valve on the compressor or worse.

On another note we really try to help people understand that freezing lines are not required. It looks cool (no pun intended) but the goal of these systems is to prevent heat soak and timing from being pulled. In the end at WOT you are pulling in ambient air not winter air on a hot summer day. Our main test mule is a 1200 rwhp 426 with a 4.5 Whipple on it running e90. Its the hottest running car we deal with. The owner sees IC temps in the 50 and 60's at the start and still can do full passes without losing any power or pulling timing and recovery after a pass is pretty quick.

Yeah, I have the whipple oversized HE, there was no room. I wasn't a fan of gutting the crash member to mount it there (I've seen the crazy custom fab) but I still want to live if the car crashes into something. The only two options were behind the passenger seat (which would have been optimal from a weight distribution and free space perspective) but the distance would have reduced the efficiency/effectiveness. So we mounted it just behind the birthday cake, which was still a challenge given I still have a sway bar. In the end, it's tucked up nice and out of sight.

I did everything IC wasn't a fan of doing, I kept my HE, I trunk mounted a huge reservoir and installed a pierberg 400, the car is now setup to run HARD for long periods of time without the IAT's ever getting into any zone that's uncomfortable. Works brilliantly for my personal use/goals.

I totally get that. I hate cutting up cars. Make it fit somewhere clean and out of site no matter how much work it takes. Its another reason we worked hard to make a brick that was as compact and efficient as possible. On the Whippled Mustangs with the larger Whipple intercooler we have the option to mount it on the drivers side in front of the wheel.

At stop lights/idle, something to do indirectly or directly with the fan duty. But I was running an aftermarket tune (not whipple or Roush) so there's that, with "standard" tune logic it might have already been controlled differently. Once we adjusted the fan duty, it resolved the issue.

Whos tune? Are you running a Roush or Whipple??
