I just had to change the aftercooler water pump this past weekend. I used a pump from an '02 Lightning. My previous stock vortech pump seized up. After the swap, i'm seeing IATs between 120 and 130. I'm running a Vortech S-trim @ 14lbs of boost thru a Vortech Aftercooler. Do these IATs seem right or a little high? Is there a way I can bring them down more without having to a: buy a different water pump or b: hook up the ice chest?

 

I'm not too familiar with air/water setups since i have a fmic, but i would guess that s-trim is making a lot of heat to push 14psi. You know how fast your spinning it to make 14psi?

Yes I know i'm spinning it over 55000 rpm when I shift. I'm just wondering if my IATs are normal considering what i'm running.

 

I would guess probably so. Maybe someone else will chime in.

those iats are decent, not bad at all, Julio from AlkyControl told me theres a rule of thumb without intercooler, whatever the tep it is outside #1=11degrees so 110degrees for 10lbs+outside temp for 10psi
