I AM TUNING A 03 SUBURBAN WITH A P1SC & A 408 & A 3 CORE INTERCOOLER. HERE IN LOUISIANA THE TEMPS HAVE BEEN IN EXCESS OF 100 WITH A TON OF HUMIDITY. THIS SETUP FOR THE PROCHARGER HAS THE AIR FILTER ON TOP OF THE HEADER & I KEEP GETTING IAT'S FROM 150-OVER 200 IN SOME CASES WITH BOOST APPLIED. OF COURSE THIS IS TAKING ALL THE TIMING OUT & RUNS LIKE CRAP. ANY RECCOMENDATIONS ON FIXING THIS/ANY PROCHARGER GUYS RUNNING THE AIR FILTER ELSEWHERE? I CAN PUT 13 DEGREES OF TIMING IN WITH NO DETONATION & RUNS ALOT BETTER...........

 

In a totally different set up (sts) I can see 200+ temps in boost, with meth. I soon will be fixing this problem with a FMIC.

On this truck (98c1500) 3.2" pulley and a P1-SC. It has a OBX intercooler I belive its 12"x31"x3" with 3" in/out.

During a humid 90 degree day we will see slow cruising IAT's of 108-116 and faster cruise like 55+ we will see 96-100 degree IAT's It seems to be 8-12 above ambiet at all times. For a long boosted run it will climb to 118 max. I have never seen higher then that. I ahve warmed over the IAT table quite a bit. So when its cool at night I will see up to 19 degrees total at peak boost w/o kr. When it gets super hot and the e-fans are on and we hit it from a hot traffic stop I will see total timing go all the way down to 13-14 w/o kr. This is wih 92-93 oct. pump around here. Its currently been about 80 outside during the day and somewhat humid. So I have been seeing about 15-16 degrees total with IAT's ranging from 80-106.

Also you can see the location of the air filter right above the header on this one. All the I/C pluming is 3" too.

The 5100lb. truck has went 13.14@106 so far with 11.5-12psi. It was 91 and humid that day 2500ft DA.

 

sts..95 deg outside...101 to 105 iat with fmic from billy at trturbo.

 

How Are You Getting Such Low Iat"s

 

FMIC on my 6.0 I see anywhere from 80-120 120 being 100+ temps outside and to the floor... Now this is only at low boost. But damm when it gets over 97+ it sure knocks the power down a few clicks..
COMMON Water/meth

171 on a 110 degree day

 

Not sure what my IAT's are or if this helped, but I relocated my filter to the stock location, but for noise purposes, the constant bypassing on the highway and the intake noise was too much for me. I would think that the intercooler would take care of the heat, I had no trouble with mine prior to relocating the intake and I have the crappy stock 2 core.

 

I have seen temps up to 150 degrees at 5psi on a 85-90 degree day.
No intercooler or meth.

 

At 12 psi of boost without the intercooler I saw 275° IATs on a 105° day......Yowsa!!!! Talk about pulling some timing!!

With my A/C chilled (40° - 45°) air/water intercooler system I see 70° to 80° IATs on a full pass at 12 psi of boost. The IATs have gone as high as 90° on a 100°+ day but with 15 psi of boost. (Still less than ambient)
