Intake Air Temp Survey

[Timo5.0]

Also totally don't care about horsepower gains. It was a simple query regarding intercooler efficiency especially for the PD blowers as this is the model I prefer this time due to sweet curve but knowing they are or were notorious for heat generation.

I did a chart from my data log you might find interesting.

Very few people have the ability to log/record and do data logging like that, at a level of precision that is acceptable.

Every person with a SCT tuner can log/record all that data. That would be MOST people.

 

[sqidd]

You have an extra special cooling system though. How much for a manifold that would fit a TVS?

$2400ish

If reading correctly the IAT are dead flat before and after up past 7000 rpm's. Can that graph be right? I checked your signature line but did not see power adder type. What setup are you running?

It's right.

That my friend is a stock GT500 blower (Eaton M122). Ridiculed as the "HEATon". Funny how no one else can get close to those IAT2's..........with "better" blowers.

Smart design FTW.:clap2:

Called and they said it wouldn't be ready til midwinter. Can't wait that long.

You didn't call anyone, they don't have a phone.

The SCT isn't going record pre and post intercooler on an air to air.
And isn't going to do it quickly as lab equipment.

Don't think anyone doubts an air to water with a couple gear pull.
(as that graph shows)

What most people talk about, is driving in 90+ degree heat doing many back to back pulls, or road racing, when the cooling system for the heat exchanger really gets put to the test.

The corvette ZR1 has a million aftermarket goodies to remedy this issue, as does the 2003-2004 cobra (and every other car with a factory PD blower, Mercedes E55's, etc, etc) If the heat wasn't an issue, these parts wouldn't be needed, and the "power fade" wouldn't be seen.

Ambient is a pretty good approximation of IAT1's. The PC does have the MAF post compressor correct?

And isn't going to do it quickly as lab equipment.

Ok, use the nGauge then. 32x/sec.

The system graphed above will run in those conditions as well if not better than any A2A. That is a fact.

We are not talking about any of those systems/cars.

The sample rate of the sensors ability to change is SLOOOOOOOOOW.
Shoot even though the temp can raise 30 degrees in less then a second, it takes a LONG time for it to catch up.

Lab grade stuff reads change MUCH faster.

Datalog speed has nothing to do with what I am talking about.
Please stop confusing people with this.

Anything can, with a short 2 gear pull.
That graph didn't prove anything.

Just like people that use air-to-air data while strapped to a dyno.
(with some pathetic fan blowing on the car)


Go out on a road course, and compare "average" inlet temp data.
Or a few back to back highway runs (like normal people do)
Thats when it starts to get interesting.

We are not talking about any of those systems/cars.

How are none of those relevant?
They are ALL relevant, heck one is even a Mustang?
They are all PD blowers, with A/W intercoolers.

Any person can go to any event with lots of high hp street cars.
And count the air-to-air's vs. air to waters.

Air to air is simple, effective, and repeatable.

My graph above was done after an hour of driving in traffic and the pull was done on the road after three other pulls. When I got home I could stick my finger in the heat exchanger tank and water was still cool to the touch. The SC was warmer to the touch than the manifold. Pretty amazing I think.

 

[Process]

The air temp reading comes from the MAF. Some or all of the centri kits might have the MAF after the intercooler, but for PD guys, we cant really contribute - we dont know! LOL.

The whipple adds an AIT to the intake manifold, but the cluster gauge still reads the MAF temperature which is hardly useful to you.

But I can tell you that my air temps pre-SC at the MAF are generally 3-5 degrees warmer than outside as long as I am moving.

Procharger relocates the MAF to near the exit point of the intercooler.

That mean the IAT is after compression, then?

Whatever dude. I got in contact with them. How is that?
