Did a pull on the way home today from about 35MPH to the top of third which is 118 MPH. IAT's were 84-86* and IAT2's went from 84*F to 171*F. I guess that's much better than 230*F on my previous setup.

Now it's time for the methanol injection.

 

That seems better man, especially on a hotter day. BTW it's kinda cool too see other peoples IAT2 with their setups

 

I got curious as well. Did a 2nd-3rd gear pull yesterday (revved to 7K+, I was around ~120mph.) It was a hot ass day (95 degrees) I hit 158 IAT2 end of the pull.

On a cooler night like the 70-80 degree temps we had last week... I'll only get up to the high 140s on the top of 4th. I never see above 160. I'm also on E85 so that probably helps.

My setup is basically every cooling mod but meth.
- Intake
- Vibrant Header & Downpipe Combo (Catless)
- ZZP 2.5" Cat Back Exhaust
- E85 Fuel
- 80# Injectors
- 2.7" Pulley
- Ported Throttle Body (BTW this is awesome - if you are having problems with your LS4 look into a ported stock one.)
- ZZP Stage 3 Heat Exchanger
- Dual Pass Intercooler Kit
- Option B Kit & Bracket
- ZZP Phenolic Intake Spacer

 

It's not that it's giving me an actual problem but because it is a daily driver it is very annoying. I can't wait to get the methanol installed on the 10GPH nozzle and a 50/50 mix. I posted my results to give others an idea. Thanks for the reply, we have similar mods except for fueling.
