FI interchiller + Stage 2 kit:

OK, here goes!

Any helpful thoughts would be greatly appreciated.

A local performance shop is doing the install. Not seeing the temps as low as I expected.

AC in car seems as cold as before. Also, my tech says the system performs better when the EMP pump on the tank is disconnected.

We have an16 fittings and insulated nylon lined rubber hoses running from tank to front of car. Since I road course my car, FI advised me to use a reservoir tank and keep the factory heat exchangers and run a temperature-controlled bypass valve. You set the temp on the a control box to ambient, then when IC temp reaches the set temp, it opens the bypass valve directing 50% of the fluid to the factory and BWoody HEs. Looks like we are getting good performance from the insulated lines because the tank temp and IC coolant temp read within one degree of each other.

Any helpful thoughts would be greatly appreciated.

^The small HE next to fan is an additional PS cooler. The HE on the bottom is a BWoody with factory PS HE in front of it.

^ No cabin AC, tank pump disconnected.

^Cabin AC on, tank pump disconnected.

Get rid of the bwoody heat exchanger, it's counter productive.

Thanks for the quick reply! The way the system is plumbed, the bypass valve keeps the BWoody and factory heat exchangers out of the loop until it the opens. All of the testing has been done with the bypass valve closed. We verified proper operation of the valve with a temperature gun.

What size ice tank is in the trunk? Seems like on most chillers, once you go over 3 gallons, they just can not chill down that much fluid but may be wrong. I know the heat exchangers are by passed for testing but may try down size the ice tank for testing.

Thanks. It’s an 8 gallon tank. We might try bypassing the tank to see what we get.

People have issues with these with the tank in the back. Fluid warms up by the time it was to run the full length of the car. You want more coolant volume as close to the chiller as possible. Like advised above get rid of the bwoody chiller, it’s just warming the fluid back up - you want as closed of a system as possible. Did that fan come with the stage 2 kit? Is that the factory condensor?

Imo, a tank on the passenger floor close to firewall would be best.

Killer setup though, like that power steering cooler

What’s the stuff you lined the trunk with?

 

[Drivin' Wheel]

Yep, The fan came with the stage two kit and it is the factory condenser.

In one of our observations, the indicated intercooler fluid temperature was the same +\-1 as the temperature of the coolant in the tank. I could be wrong, but I don’t think we’re getting much temperature gain between the front and rear of the car.

I don’t remember, it was a few years ago….vein effort to reduce the drone of the factory exhaust system. I ended up getting a Corsa Xtreme exhaust which is quiet(no drone) during cruising and very nicely loud during acceleration!

They can chill any amount of fluid, it just takes longer with more volume.

When I added a Killer Chiller to my 16 Scat back in 16, they recommended around 2 gallons.

That's typically all that is needed for 1/4 runs.

I’m making a custom tank to put where my windshield washer reservoir is. Should be cooler than the bmr above valve cover

 

[Unholy707]

Should be better for the intercooler pump as well since it’ll be in line with it

That's a d*** good idea please share when you get a design if you're willing.
