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

DarkPira7e 08-08-2020 07:56 PM
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?

To be precise, 100 pedal, ambient 36 C(95-96F), iat 41 C (105F). it was kinda hot today.

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.

Side 08-09-2020 09:22 PM
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.

Almost all FI kits maintain MAF in stock position, so everyone's IAT measurements will not show the real deal. Given your location, the MAF itself may be heat soaking as well.

120F or 50C post blower wouldn't be anything to worry about, we get that ambient near the road around here.

I've seen 60C on the pre-turbo MAF during a track session before I decided to pull the trigger on meth.

Pretty sure all the centrifugal superchargers have MAF post blower. and a lot of turbos as well. positive displacements are the only ones that would need to relocate.

yeah i know yours is post blower so your getting "true" IATs, but i still think they are possibly falsely high when under boost just because of close proximity to engine and the MAF "housing" is metal which probably heat-soaks and keeps the MAF from reading the lower boosted air temp correctly. Even if this isn't the case and its reading correctly at 120F in 90F ambient that still isn't bad.

My JRSC setup hit 150F IAT at the track last month in mid 90F summer heat.

See this is cool for me cuz youre hitting 150f with an intercooler and me without one I'm hitting 120f

Good point, looks like a lot of them are! My Avo kit is pre-MAF so I guess I was biased.

On this point I feel like I should be monitoring the post-intercooler temps more closely...any recommendations as to gauges or tapoff ports on the manifold? The only ones I see are the PCV one I've deleted on top of the manifold, and the evap one below.

86TOYO2k17 08-13-2020 03:55 PM
@TurboBRZ_UAE One of the MAF wires is for temp, you can NPT tap somewhere post FI put in a threaded temp sensor cut the one maf wire and wire it in. Then the IAT the ecu reads will be accurate post FI temps. Someone had a small write up about this for more details and which wire etc, I think it was @Kodename47

Kodename47 08-13-2020 06:32 PM
I can't find the info on the wire colours but it just needs 2 to be taken from the MAF and passed to an IAT sensor. I can't find any pics from my install so I'll have to go and have a look in the daylight.

Edelbrock uses a TMAP and hijacks the IAT to give you a proper charge temp reading.

CSG Mike 08-13-2020 11:53 PM
I typically see about 30F over ambient at 10.5 psi.

GReddy T518Z kit, with JDL intercooler upgrade and custom ducting.

Oil temps never exceed 225F, regardless of ambient temp; turbo is oil cooled.

ML 08-16-2020 10:29 AM
You got me thinking so I made something to help with temps...I was able to get my temps down 10 degrees during my last track session with about the same ambient temps with this:

I am currently not running a fmic. That was the whole reason for the question. Because these are ESC and not like a conventional turbo or SC. The idea was that if my charge temps are just about the same as those of other FI setups then there would be no need for me to use an intercooler but if my temps are higher than other setups then putting one on should be considered.

Typically compound boosting feeds compressed air into a secondary compressor, so 10psi and 10psi from each doesn’t equal 20 psi, but typically more like maybe 30psi. I don’t know about electric superchargers, but I would imagine it would be similar, which is why I asked.

Centrifugal chargers generate heat no matter what they are. They are compressing air and are operating at high rpms. Electric superchargers are typically not generating enough heat/boost at 2-3psi to need a FMIC. Some people with turbos or traditional superchargers don’t run an intercooler with 7psi either, but it is a good idea. In fact, most professional compound charging setups have two intercoolers after each charger, so air temps drop between chargers and after; the effect is better if the air feeding the second charger is not only compressed, but cooled. It leads to better efficiency on the second charger and IAT are better controlled. Obviously you aren’t running enough boost for you to consider that—just saying.

You could have the filter sit behind the fog light bezel and just put like a half circle plastic on the top end of the filter to make it look like there's a fog light there.

I'm not quite sure how the science behind compound turbos work but when it comes to ESC . Cleetus McFarland on his youtube channel tested two torqamps in compound form each turbo alone made roughly 5 psi and together they made 8psi. It's what prompted me to do a twin ESC set up. My ESC alone made roughly 4psi each and together they make 7.2.
