and the EFI Whipples with the HP Holley ecu's idle like a 502......

Heres a good read . He makes a good point about the location of the IAT sensor. Many times its in the piping after the intercooler on a centrifugal, and on a roots/screw, its in the actual intake manifold. It be interesting to see both setups taking readings in the actual intake manifold before the air enters the cylinder.

Hes absolutely right on how at cruising, you get higher iat temps , because the air inside the intake is being recirculated. But as soon as you go wide open, that air gets flushed down the toilet basically. Ive seen that on dyno pulls and on the water with roots. The gauge plummets when the throttles are opened fully.

Ok you are making good points with quality information here. I want to ask what would be the ideal whipple charger and huge intercooler, to get below 100*
yes 100

MILD THUNDER

Eddie young could answer that. I recall him saying on some whipple setups he's built, he sees less than 100* iat temps.

whipple makes the standard intercooler, MOAC, FOAC, and Dennis Parvey was making some killer intercoolers as well.

Sorry, but that's not true. Whipple's intercooler is made from CuNi. Procharger uses an aluminum core. The CuNi is extremely expensive. However, they use it for a reason. That's because it has some of the best heat transfer abilities of any other suitable material. Plus you have the fuel going through the blower as well. I've had them form ice on top of the blower, even in summer.
If you do a front mount Procharger, you will kill ALL of your forward working room. You will play hell getting to the outside of the engines.

To make 1200 hp with a Whipple on a 572 is pretty brain dead. All it takes is a 4.0L and a MOAC. However, if you think that you may want more, go to a 4.5L. There is no need to use anything larger than a MOAC intercooler.

Your IAT will depend on ambient air and lake water temp. There is really no way to say that temps will be X on any given day. They will vary.

They will idle better, run better, not sound like a rock crusher at idle, etc. with a Whipple. The vast majority of my customer could care less what I use to make the power, whether it be a Whipple, roots, Procharger, turbo, etc. They want to know how much it costs, how much power it will make and will it live. So, I pretty much have free reign to do whatever I want. I do build Procharged engines, as well as Roots on a semi regular basis. However, 95% of them get a Whipple.There are several good reasons for that.

We would be glad to help or set you up with what you need. You can reach me anytime at 615-216-7449

This is another thing I was thinking about,If you have to push or suck the sir through the intercooler mounted on te intake area below the whipple does this not make alot of resistance, well I am talking about this kind of intercooler below, would this hurt performance? all the air through that small square and then there is that mesh there also?

that pic is of an automotive cooler, here's one of mine, no need to second guess the Whipple blowers their a proven reliable product.

You sure do make every aspect of a traditional build difficult and over complicated.
