Forced induction temps?

I'm curious to know what kind of intake air temps everyone is getting under boost.
What forced induction system are you running?
How much boost?
And how what are your IATs at during boost?

Anywhere from 210-230, edelbrock stock pulley and no oil cooler. It gets up to 230ish if im going uphill in traffic or whatnot.

Other than that it's been pretty good.

I'm in a really mild bay area climate though

IATs during boost are normally fine. It's when you stop moving after being in boost that you get heatsoaked

Are these engine temps or intake air temps. I'm running a boosted set up making ~7psi no intercooler and charge temps reach 120°F I'm trying to see how that compares to other boosted applications if I'm running to high charge temps or if I'm just in the ball park.

I haven't even measured IAT at all tbh, those are just my oil temps. I'll check it out next time i take it out. I feel like that's something that's going to vary widely depending on ambient temp. Your ambient temp atm is like 30 degrees F hotter than where i am.

edit: just re-read the thread #1 post, sorry for the dingus response.

I live nearby to you so my temps should a little more pertinent to you.
Works stage 2 turbo. IAT is at 99 F during a pull.

Whats your turbo setup?
7 psi with no intercooler? I think i know what kit youre running. If it is what i think it is, I'd run an intercooler. You running an oil cooler?

I'm running a twin electric supercharger set up. And that's not bad at 99.

Driving home today on a 75-80 degree day I was seeing 100-110 degrees IAT, at least when I got off the freeway. It was highest when idling of course.

Edelbrock Supercharger running approximately 12 PSI of boost at redline.

IATs are 20°F above ambient while driving, but I haven't installed my hood vents yet... hoping they will help a bit.

@Side @decap

Did you relocate IAT sensor to post blower?
Or is that just pre blower temps from the MAF?

I think it's just temps from the MAF, we didn't relocate anything we weren't told to by the instructions haha

Yeah you don’t need to. But it’s not real IAT temps.

OP trying to figure out what post FI boost temps are if he should intercool or not. As far as i know all PD blowers only measure pre FI/boost temps. So we have no idea how effective our intercoolers are. Unless relocated.

Need to ask turbos and centrifugal supercharger owners as they can give a real ambient temp vs post blower temps.

Also temps while cruising are sort of irrelevant especially for OPs question. Need IATs during a long pull.
