Big Diesel I/C?

[motorhead]

I have an opportunity to pick up a 20 ¼” row intercooler from a 95ish International w/ about a 300 Cat motor. It is all aluminum with cast side tanks. The inlets/outlets are ~3”. And its core measures about 23x12x3. It is very clean and in good condition.

What are the odds that this is a worth while purchase? Does any one know where to get cfm flow and pressure drop/efficiency numbers across the core?

Thanks,

Dont do it! The only inexpensive Diesel intercooler worth getting is the Ford Powerstroke. Talk to Redshotair or Cool84 as both of them have installed them with excellent results.

Are you kidding? The semi intercoolers are often Garrett cores and are sized for much better airflow than the Powerstroke IC. I cut a Kenworth core in half to make 2 front mounts several years ago; we had about $300 in both of them and they've both given excellent performance. One's been 11.70s@118 in a 150k mile stock long block T-type with a TA-60, the other's been 12.20s@20 psi on another 100k+ mile stock motor with a TE-44. Before anyone asks: no, I didn't do wind tunnel tests on the cores.

Kendall........A buddy of mine was talking to OrlandoGN and ScottyGNZ. Both had used Izusu NPR intercoolers and experienced some major pressure drop across the cores. Maybe the ones you had were better. But, for the money, you can get a Powerstroke unit or fabricate a new one with a brand new Spearco or Griffin core.

Lee & Kendall,

Thanks for the replies. Lets not fight here

I can likely score this "unknown" I/C for less than $200 Canadian. Aka ~$150 US.

The piping is easy to obtain and fabricate (I can weld)

If I don't take it I might pass it along to a friend doing a Turbo 2.3L Ford with a T3/T4 who needs a better than stock I/C. Which I am sure this fits.

Where would I go to get one of these puppies tested for flow? A rad shop?

Thanks,

I am talking (and I presume the originator of this thread is talking) about semi (tractor trailer) ICs. I remember Scotty talking about his testing with Mike...no big surprise. The Isuzu ICs are for those smaller delivery trucks...they're about 2" thick at best. The core we used was 3.5" thick and about 3' by 3'. It was a Garrett core and free, to boot...I've seen several similar ones go for ~$100. A decent sized Spearco core runs $600 and up.

The jury is still out in my mind as to whether that Powerstroke core is a smart choice..

dont do it

The I/H intercooler that i put on my car killed the 60' and i did not have the fun of cutting the core support and the headlight buckets. (just kidding) You just have to cut the inlet/outlet off flush with a sawzall and a wood blade. Then cut some ovals out of sheet aluminum to block the holes. Then take a hole saw and drill holes into the bottom of the tanks and weld on 3" cast elbows and plumb it to the turbo and throtle body. There is no way i would take this off for a powerstroke unit.

Walt! Do you have pics?!

Thanks guys... I take another peak at it and see if I can get it flow tested.

Sorry no pics. But if this has the outets at a 90 degree cast into the bottom of the tanks it is about the same size as a dequick v2. (at least the old 3"thick v2)
