JDM Heat Exchangers in stock!
I have a dual tempertaure gauge which is set up to read the temps after the supercharger and after the intercooler. I was running a 6lb lower pulley and temps would get extremely hot during high speed closed track freeway runs. I think this heat exchanger will really do the trick for me.
I don't remember the exact temps I would run. I do believe they were around 300° after the supercharger. If this heat exchanger would get those lower it would be worth it. I'm sure a larger reservoir would also help out.

Just curious,
Wouldn't a small fan(say an 8" for around $60) behind the stock heat exchanger produce the same results as a bigger aftermarket heat exchanger??

I will post pictures of the detailed instulation in the next couple of days.
The install takes about 45 minutes .
All hardware included.
We will be installing one on the MM&FF truck tomorrow on the (Frig).
Hooking all our equipment up to it so the air charge so the air charge before and after the heat exchanger and befroe and after the supercharger.
We have seen great imporvement in those who use big pulleys for everyday street use.
We will keep you informed.

Very nice product! For $465, you get increased performance and increased reliability. The rule of thumb often used is 1-1.5% horsepower for every 10° reduction in intake temps. If this rule holds true, the 60° drop advertised above would provide 24-36 rwHP on a 400 rwHP engine--in the real world. Is this what you are seeing, Jim?
My suspicion is that minimal gains would be apparent on a dyno run on a cold engine--the larger heat exchanger would likely provide gains only in sustained or intermittent boost operation (i.e., the real world). The rate of heat absorbed by the intercooler core is defined by the size of the core and the temperature of the cooling medium. The heat exchanger would only allow the water to heat up more slowly and reduce the ultimate temperature of the water at equilibrium. Even with the stock cooler, the water would take more than a few seconds to heat up. So I would not expect to see big gains on the dyno. Once again, does this square with your test data, Jim?
I'm definitely going to order one of these puppies for my BONE STOCK engine! Nice stuff.

TIm,
You only do a third gear pull on a dyno.
So if you start off cold, say 80 degrees you are only going to reach 100 at the end of the dyno.
As for quareter mile we had tested a truck at English Town Friday before and after the truck picked up between 12 and 1,400 's hudrads according to my math.
On a truck that was running 12.1's to 11.96.
I would say between 14 and 18 HP.
We are also going to be doing a five lap road course test on English Towns road course.
Hope this helps

Boy! It sure would help out us Texas boys even better with the humidity we have. I am already day dreaming about having one.

June 2002 MM&FF page 226:
...What was real impressive was the fact that the charge temperature at 21.6 psi reached 320 degrees exiting the blower but was reduced to peak of just 106 degrees. The stock intercooler system running ambient water (no ice water tricks) pulled out over 200 degrees of charge temperature. I guess Ford suspected Lightning owners might be subjecting their trucks to some abuse."
Let's look at the data. At 20.6 PSI, the air leaving the SC was 307 deg. The air exiting the IC was 107. Assume a 75 deg day. Intercooler effectiveness = (Tin - Tout)/(Tin - Amb).
(307-107)/(307-75)= 86% effectiveness.
Assume a 95 degree day and the effectiveness jumps to 94%.
Even assuming a 55 degree day, the effectiveness is still 79%.
These numbers are nothing short of phenominal (and suspiciously low) for an air-to-water intercooler. [deleted] Although JDM was not involved in this test (another leading tuner was), it will be very interesting to compare the promised test results from Jim with the observations from the MM&FF article.

careful what you say or or you will be pulled from the mag
j/k
I LIKE IT.
It is true ALL the cooling system for our trucks work great, not great, but gggrrrreeeaaatttt, but when you go beyond the norm for these eatons, the air must get hot as in a 6 lower and something upper, daily driven on the freeway, but not abused daily, if that is possible, that high rpm with the blower spinning nonstop must produce some heat, so big pulley guys better check it out, but damn $$$$$$$$$$$$$$
Its in the mail
