Been reading on chevy high performance that you can slow down the current on the coolant pump and get better IAT's. Anyone know how i can do that or how they did it?

This is the article i read
Chevrolet Silverado SS Supercharged - Chevy High Performance

 

put a potentiometer on it and drop the voltage on it.



all you're doing is keeping the coolant in the heat exchanger longer.

 

That and less heat will be added to the water by the pump at a lower voltage, but I think that is pretty negligible. Most of the ford guys like to put huge pumps on their cars/trucks. Interesting gm guys want to go the other way.

In my experience with blowers, the pump and heat exchanger doesnt make any difference when you actually need it; while the throttle is down. All of their advantage is in recovery time, which you dont really care about unless you are road racing... The intercoolers on the popular blower kits are just too small due to the limited room.

 

Potentometer?? haha

All i want is some cooler IAT's even if its 10 degrees! i just installed a meth kit and that had no affect on it so im just trying to find/try anything thatll work

 

I spilled some meth on my hand today while filling up the res and my hand got really cold, so it must do something in the engine
Try spraying more meth...

 

To find out what is going on you could measure water temp before and after the heat exchanger and intercooler....

 

Im using the red nozzle good for 350-450 hp, i think, so i dont wanna shoot more in there...


After every WOT pull??

 

It would be more useful in real time...

 

but the temps are low on iidle up till about 70+ mph on 3rd gear. thats when they start hitting 160+ degrees

 

What blower are you using and what pulley size?
