Most air temp sensors will barely have started to respond in that time too. Even the so called "fast acting" temp sensors....are rather slow. So most data people have....isnt what they think it is.

Use the same GM sensor on 3-4 second 1/8th mile cars and they read just fine. If you can max out the sensor 2 seconds into the run it appears they respond plenty fast enough to read a lazy 1000hp 100-200 degree reading on the dyno.

If you're maxing out a typical air temp sensor in 2 seconds, then you've seriously fucked up high air temps.

Some proper testing of some temperature probes, including a "fast acting" air temp sensor....which was even slower than a slow thermocouple.

Appearing they respond fast, and actually responding fast are not the same thing. Does it always matter ? not so much perhaps, but they are still very slow.

Twin 94 or 98’s on 40+ PSI with no IC make some heat but doesn't matter for the fuel used. Even a single 91 on a street car maxes out the sensor before the 1/8th on pre IC temps. Really doesn't matter as long as you tune for what the engine wants. Cars have gone just as fast with 175+ IAT’s as 100* IAT’s, E85 and other fuels just don’t care as much as pump swill.

A normal thermistor air temp sensor will never read no IC temps correctly ( unless very low boost ). They simply do not have the range.

But quite correct, if the engine is tuned for those conditions and it is happy....there is no problem.

That isnt to say things could not be improved with cooler air though

It's an engine dyno with a 300 RPM/sec rate, so roughly 14 seconds. The dyno pull will be a lot longer than any quarter mile pass the engine will ever see.

Ding ding ding.

Don't waste your time on spanky there

300 RPM/sec and a 14 second pull? Why such a wide window?

Would have been nice to see this test with the usual Chinese crap so many on this forum seem to love.

Although still a good comparison of a decent intercooler against a better one.

Steve, you beat me to it! And in that test the only change was the intercooler. More boost and less heat! Same pulley, same engine, etc.

Also worth watching the Banks Power videos on their supercharged duramax. Gale goes into a lot of detail on how much power the intercooler is actually adding. Turns out it’s more than the blower!...

this is isn’t to say a cheap intercooler won’t work, just you will have to work the engine, turbo and everything else harder to get the same results. The same as a cheap turbo vs a optimised one.

Sheara also dose a pretty nice intercooler using (I think) 2x3inch thigh Garrett cores for the big HP guys: https://shearerfabrications.com/coll...31058173558843

Interesting. No one mentioned a Procharger as a choice for the OP as an inter-cooler thru the entire thread. But now are posting videos using Procharger inter-coolers to show the difference between a good inter-cooler and an internet inter-cooler. So maybe the Procharger inter-coolers aren't so bad after all. But no one mentioned it.

BTW - note that the Procharger inter-coolers tanks are not cast. Just speculation, but IMO whether the tank is cast or not is relevant once the inter-cooler heat soaks. Plus a cast tank inter-cooler weighs more like my heavy Mishimoto with cast tanks.

Looks to me like I could dump my big a_ _ 4 X 26 Mishimoto inter-cooler with a smaller 3 or 3 1/2 inch Procharger intercooler and do better.

Cast or fabricated is totally irrelevant.

Construction design is relevant. Core design is relevant

I don't think there is an argument that a better intercooler makes power power at lower boost. It's do you care. When a price difference of even 300 is the cost of a turbo, not everyone wants to spend that money on a better FMIC.

stevieturbo

Seems most here dont care, all they want is cheap chinese parts and junkyard motors.

Thats a bit of an exaggeration. It's not all sloppy mechanics.....at least not intentionally

i like to call them "WALMART SWAPPERS"

my garrett guy tells me that a garrett IC might drop 1/2 pound of boost from inlet to outlet
