i have a 06 gt with a saleen sc,auto trans,9lbs boost,460 rwh.do i need to run a larger heat exchanger for just street use.if i go to 12 to 13 psi would it be needed?its not a daily driver.

 

I am going to be running somewhere around 14-16psi and would like to know the same question???

 

Where do your IAT's run??

 

Well to be honest my motor is in the process of being built so not sure this is more of a preemptive question???

 

and i can tell you all you want to know about a carberator but forget fuel injection.

 

Keeping the intake air temperature down is a cost effective way of preventing pre-ignition and motor destruction.

 

Yeah I decided that is def. needed as you are right great way to prevent a catastrophe!!!

 

A larger heat exchanger will help keep the temp down and by doing that will prevent the computer from pulling timing due to heat soak.

It's unlikely that you'll prevent detonation with a larger HE. If the tune is on the ragged edge and is too aggressive then you will, but I wouldn't recommend running a tune that aggressive in the first place.

I had the Saleen Extreme HE and it was very good.

 

No I am going to be running my setup well w/in the limits I just figure a larger HE is just that much more insurance!!!

 

My question was to the OP

I just upgraded mine to an Afco dual pass heat exchanger, but will really not know the impact until next summer when things get hot around here again. My IAT's never went over 130, even when sitting in traffic when it was 90 outside. The key benefit of keeping your IATs down is reducing the chance of timing getting pulled in due to excessive heat... which obviously kills HP.

 

Killing HP is exactly why i'm installing a dual fan large exchanger.
