Retune after correcting all items pointed out by folks above. Good luck and Godspeed man. Good catch. You may have just gotten lucky 🍀

as an add on. Do the cleaning as pointed out above. Also run a hairdryer through the unit to see how well it flows and make sure it flows properly without leaks. All bets are off on prior work.

Good luck.

I don't think there has been any detonation...the exhaust pops sometimes from running rich and hot but there hasn't been any weird noise or anything. Oddly, the intercooler itself is quite clean, not a drop of oil in it.

I've spent the entire year that I've owned this car undoing and fixing mickey mouse work. The car was a good deal with a nice list of parts, but I kind of wish I just bought a stock car that wasn't messed with.

I'll be checking this SMIC really carefully tomorrow before I reinstall it.

I had really bad luck on my 94 Supra this month...just happened to get a bad set of valve springs (from a very reputable company) that were slightly out of spec and a "reputable" machine shop that tried to force them in with more mickey mouse ****. Screwed hard from both sides (valve spring company and machine shop), it's been kind of shitty.

Hopefully you are out of the woods on this one. Soiled underwear. But clean IC. Ok I couldn’t resist either. B)Run a hairdryer through it man.

By running a hairdryer through it you mean point it through the hotside and the air should come out of the cold side at the same speed?

Also, I hope the heat from the boost killed whatever bacteria was in that underwear.

Edit: I just realized where all the oil went. Everyone should install the IC self cleaning system to soak up oil.

YEs on the hairdryer. Clean out the IC it may have some “soiled oils” and then blow dry it immediately after and check air flow and seal. Good luck. 👍

Soiled children's underwear in the intercooler... It's threads like these that make this forum great!

Glad you found that! Something certainly wasn't adding up. I was starting to think your temp sensor was bad or the stock sensor location was to blame.

There was a funny (true) story on the forum years ago. Some dipshit decided to wrap a t-shirt around his intake pipe to use as a filter. He revved the engine, and the t-shirt got sucked into the pipe. If I am remembering correctly, the shirt ruined his turbos, and some of it wound up in the intercooler. What a mess. It just goes to show that you cant fix stupid

Maybe you bought this car from the same guy lol

Just wanna chime in an additional "Holy ****". On one hand, hell yeah you found the problem and it was minor. On the other, it makes you wonder about the rest of the P.O.'s work.

lol a greasy pair of Underoos stuffed in the end-tank. That's a new one! Maybe he had some kind of blow-by issue and an intercooler full of motor oil is what made him hack up the IC in the 1st place.

Now I've seen it all... I'm actually surprised that you were able to see temps in the 40's (C) on 70F days

When I bought my PFS SMIC (used) I blasted it with water using a garden hose to get debris out. Not sure what prompted me to do that.

I'm thinking the guy has kids and kids do weird **** sometimes. Like stuffing their underwear in intercooler pipes

Oops!

Hi guys, I want to apologize for my previous comment on the GReddy VMIC. I made a mistake by reading the IAT when the car is sitting. Yes, 63°C is what I got on a very hot day, stopped by the road, just finished a 20 min drive in the boost. Hope my mistake doesn’t stop anyone from going for a VMIC.

Result

Just did the same run today, comparable ambient temp and driving conditions. IAT is around 45~47 °C even though I tried to push harder. Did some 2nd through 3rd pulls and not seeing any notable increase in IAT.

Sounds more like it. You do heat soak though to right? But I assume that clears up almost instantaneously when you get moving?

I believe so. The sun was very bright on my first drive, making it incredibly hard to read my PFC commander. When idling at stop or hot start, the IAT sensor is literally measuring the heated UIM temp. That heat sometimes cause unsteady idle. I paid more attention today and did not stop at all, but it's reasonable to say that the heat soak will go away quickly once you hit speed.

So we just street tuned it again yesterday and it was easy to get it running well within 15 minutes. IAT's are still a little high but better. Running on the freeway in 5th at 80mph was about 38-42C, giving it some boost and keeping speed up around 45, and then sitting at lights or in traffic was still around 52-55.

When my other project is done in the next couple of months I'll take apart this car and possibly do a pre-emptive rebuild and install my single kit + a vmount.

Sounds about right. Driving in 80s today and humid. Got about the same range on a Greddy SMIC. Probably need to extend the ducting shroud front area further. And change the iat sensor to a fast reacting one.
