What intercooler are you running and for what reasons have you made this selection?

[gunzandgearz]

Slic will work for sure, ive ran about half a dozen different ones but you take the same 10sec car and change to a quality front mount you will pic up in every way, mabe not pressure drop, but im guessing it will cost more to build a good slic then the cost of a fm? and it wont be easy to improve on the current Pte unit..

Yea and that's all im looking for if I can get to the tens I shouldn't have much problem smacking anything that pulls up next me

Agree.

Hope it works out for you guys, getting ready to start the process of 800 horse build so maybe ill be one of your first customers

Trusty old PTE front mount here. Bought it ~12 yrs ago because I wanted less pressure drop and less charge temperature than a stock intercooler. Have thought about replacing it recently but haven't because there just isn't anything out there that's really any better.

This new intercooler is looking like it will have something to offer. Some new technical features that are worth something. Definitely interested.

Side note: bolt in preferred, wouldn't want to hack holes in anything.

Some things to consider.

The alcohol is not a substitute intercooling. You have to look at the properties of the liquid, saturation temperature and saturation pressure. At 22 psig the saturation temperature(boiling point) of methanol is 199 deg F. As the pressure rises or drops, correspondingly, so does the saturation temperature. Your ability to cool below the saturation temperature in a practical manor with methanol(or any liquid) is virtually nil. You get the most cooling effects when it enters the combustion chamber, and it flashes to a vapor during the compression stroke, cooling the charge and inhibiting detonation. The higher fuel to air required for methanol means you get greater cooling while being able to optimize the A/F ratio over gasoline. It is the latent heat of vaporization that lowers the charge temperature as the sensible heat is very small. A hot air car can benefit quite a bit from alcohol injection because the manifold temps are well above the saturation temperature, so the alcohol will flash to a vapor in the manifold dropping the charge temperature.

When someone is reading low temperatures while spraying alcohol, the alcohol is wetting the temperature sensor, pulling the reading down to the liquid alcohol temperature. In addition, the a constant process of wetting the temperature sensor with a constant evaporative process taking place on the surface of the sensor, you get a low temperature indication. It is almost identical to the process of how the wet bulb temperature is determined for the weather. The air stream is going to generally be whatever temperature it is when it exits the intercooler as it takes a fraction of a second for the air to flow into the combustion chamber from there. No time for a significant amount of evaporation to take place. Evaporative cooling requires a large surface area and residence time which don’t exist in the intake system of the car. The difference on the temperature sensor is that a quasi-steady state condition has been set up where you are continually wetting it with ambient temperature alcohol, and a continuous process of evaporation local to that surface is taking place.


The interesting thing going here is that the effort is looking to optimize heat rejection vs pressure drop with existing hardware. Good luck, looking forward to the results.

This is why johnplogi was seeing a drop in intake temps, but no increase in power, the temps were dropping because of the alchohol being sprayed into intake dropping temps but not dropping actual air density. The temps should actually be measured before alchohol injection happens to get true temp readings.

Still Have My Kenne Bell Big Boy from 6/94 Not currently installed. I Have some info from that era.

I don't have alcohol injection, just run straight e85 through the fuel system. No alcohol is introduced before my air temp sensor.

no he is not moving any more air through the motor.

pretty neat reading that, I ran one for a long time did its just up to 35psi

 

[Pronto]

Interesting read. Seems like the more things change, the more they remain the same.

 

[V6sleeper]

Pretty cool read and design, but i think the inlet pipe is too long entering on the drivers side, bottom tank should be reversed.

Yea I was wondering about that as it was late when I posted that last night and thought you might have been injecting, must just be restricted on back side. How much power are you making?

You need to put that thing on car and gather some data. Inquiry minds want to know.

I wonder if anyone has ever run any back to back tests to see if a little less pressure drop made more power since the air would stay in the cooler a little longer instead of just going for the least amount of delta p with the current core designs.

John Plog doesn't have any wet flow alcohol injection. His engine is E85 only. His car runs high 8's TSM legal

It's been proven plenty of times when the intercooler was inadequate. Getting pressure drop down to 1-2psi while reducing drive pressure 10psi. Some high hp v8 cars have picked up over 100hp.
