I live in SoCal high desert area (Don't judge, its a job) and in summer we can hit 110+ ambient. I'm looking at Whipple/Maggie/ProCharger and wondering what system has the best IAT management? What does it take to keep these systems cool if your hot lapping (Big Willow for example) in 110+ heat? Any one have first hand experience? TY!

They all will have high IAT's in 110+ ambient temperatures. Higher octane fuels, e85, and/or meth would help keep detonation at bay... Killer chiller might be a good option as well.

I was thinking a chiller would probably be mandatory and Meth would be a good safety blanket. I would love to eat corn unfortunately e85 is next to no-ware near me that I know of or can find. Even 93 is hit and miss. In my local area. I'm probably stuck on 91....

I don't know if it even matters between systems on extreme summer days, its all going to be HOT. Maybe if one system has better cooling than another or maybe if one system runs at lower boost/RPM to make power it would help?

I run a Whipple @ 8-9psi but I don't deal with those kind of temps. I ran my car up to a buck fifty in Mexico and the IAT's never went above 130 starting from 118 with 85 degree ambient temps. So add another 20-25 degrees to those numbers with your conditions and you would be looking at 150+ IAT's so it would be pulling some timing. With a killer chiller you would probably be fine. I know CSP really likes them.

I believe Killer Chiller and the like probably won't work well except on a strip. I believe the A/C turns off at either WOT or whatever the setting is (you can manipulate that setting with HPTuners and such). So - if the A/C isn't running, the chiller isn't chilling.

If it above 85 I run the AC anyways. I think this is what I'm looking for but I have 0 experience with FI.

I haven't run into the 100s yet, but in the 90s my car runs IATs with an air / air and centrifugal S/C (Vortec Intercooler / Novi 1500 ) and cruising I see 8-10 degrees above ambient at any given time.

I also run meth but it doesn't come on until 4psi, but once doing so after about a second the IATs are in the 50s under a pull.

You can not really compare Centri IAT's to PD IAT's since the sensor is not in the same location. PD units place the sensor in the supercharger, so they read a higher temp. The tune is modified to account for it.

I can do several pulls back to back when it's 85 degrees out and still hit it's targeted 21 degrees timing advance, so it's not getting hot enough to pull timing.

I do think Centri's run a little cooler but it's not as drastic as the IAT numbers show.

Would Centri's have an advantage in heat soak or is it not enough to matter?

For road course I would push you toward a Whipple or maggie to keep cooling in check.

The delta temps are going to be good you will just have less power than someone at 50 degree ambient.

So for example if you start at 50 your IAT will be say 30-40 degrees higher same if you start at 110 your iat will be 30-40 degrees higher.

The best you could ever hope for is to achieve same as ambient.

Higher octane fuel is your best engine protection and ability to make good power at high IAT.

Call me for more discussion on this subject.

No, seriously, that is really great info, TY! Interchiller = Heat problems probably a non issue.

Also 2k for these catbacks are a rip off but that is a rant for another thread....

I'll try to get a hold of you tomorrow, TY!
