Intercooler flow January 06, 2009 09:54PM
Was wondering if someone could give me what kind of flow numbers the superfarm guys are running. In other words how big of an intercooler do you need so it dosent restrict your flow? Is 1500 cfm enough or do you push more air than that? Thanks in advance

At 100% volumetric efficiency & 640 CID, 1000 CFM would support nearly 5500 RPM, so that should be plenty.

Turbo charged and supergharged engines run over 100 % eficiency. A well built naturally aspirated motor will be close to 100 % alone.

They are over 100% when you figure ambient air into the blower, but the blower compresses the air which makes it volumetrically smaller. For example you could have 1000 cfm into the turbo at atmospheric pressure, but something like 400 cfm at 40 psi & a much higher temp. I've never bought an intercooler, so I don't know how they rate them, but the volumetric airflow thru it will be less than 1000 CFM & a NA oem tractor head will never flow close to 100% VE at high rpms - they are not anywhere close to performance automotive heads.

Deere says as a rule of thumb the best they can get on a na 6 cylinder is about 80%

you need to look at how many lbs of air your turbo charger is moving( air map) and the the air density, along with the air discharge temp to properly size your cooler. If your turbo is not large enough and you turn it to fast it will fall of the map and super heat the air. There are very few super farm turbos that will move over 100lbs a min, which is still under 1500 cfm.

Well I would say most superfarm charger's move over 100 Lbs/min I know an HX60 in stock trim moves .95 Kg/sec. I was thinking I figured that out one time and it was real close to 120 Lbs/min

I agree on the lbs of air per min that the hx 60 puts out at stock trim but when you factor the barometric psi, ambient temp,vacuum draw at inlet, inlet psi. inlet density,compressor wheel efficiency,isentropic efficiency and ic pressure drop it changes the actual mass of air that you are pumping. I am not saying its not possible, it would probably be more likely if you have 50 degree air going in the inlet of the rather than 90 on a july day.

Can you size the innercooler to big? If you buy the largest one they make will it hurt you?

Only in weight and price.
