IAT w/a2a

[cvcsmkr]

i have a kb a2a, pte 44, stock motor.
at night 70-80* im getting 90-110 iats, 20psi of boost, no kr
warm day, 90+ im getting <140*, but im getting 3-4 of kr with only 18 psi of boost.
are the IAT's making that much of a difference?
if so what else can be done to bring the temps down besides alky?
i have turbo wrapped, the cold side of intercooler piping wrapped.

Re: IAT w/a2a

You can install a CO2 intercooler spray bar system.
Or, I heard these work OK Ebay Item number: 140024532805
I think you would be happy w/a alky kit that should fix the KR problem.
Also, the KB intercooler core is a little small, you can always install a larger intercooler.

yeah the kb core is kinda small.
as far as a bigger core, its pretty tight in the stock location, i dont think you could gain enough to make it worth it.
i just really dont want to add anything else onto the truck that could be a problem in the future. the sy has no problem developing all kinds of issues by itself.
just trying to keep it simple, but running good.:dunno:

Re: IAT w/a2a

Do you have a scoop on it? Like a "blade of death" or something like that.

Without increasing core size the only way to gain effeciency is to increase flow. A scoop can help with that some.

Re: IAT w/a2a

Where is your turbo getting it's air from, under the hood heat?

yeah, the core sits at a 45* angle, and there is a blade that is 90* of core.

well i fabbed up a temp cold air kit and it was pulling air thru bottom of fender.
then i put a cone filter off of turbo.
datalogged both and there was almost no difference.
so i just have the cone on there now.

So you are saying your filter is picking up underhood engine heat?
I think you should go back to your cold air kit ,even though you say there was no difference in your temps. :2cents:

Does your blade go up and trap the air from the sides as well? You almost have to force that air to go THROUGH the core, not just run into it, and flow around the sides.

Got a picture? That would speak volumes.

I've not seen the intercooler core size on the KB kit, so I'm not sure on that one. However there is an RPM kit on a local truck that has IAT's around ambiant +10 at cruise, and in the low 120's while under boost @10psi....Thats from a PT52 turbo with no filter (yea, no filter ) Can you compare the core size to the RPM kit so we have a frame of reference?

Re: IAT w/a2a

In the chip you can pull timing at higher IAT's. You would probably pull less timing to eliminate the KR than the factory KR pulls. The factory tries to overcompensate, and it also has a decay that may hold the retard longer than you need.

Your still not going to make more HP with hotter IAT'sthan you do with cold IAT's, but it should be less of a drop in power when your IAT's are high.

here is a pick of a modified one, i ONLY have the blade on the bottom, nothing on the sides.
