intercooler opinions?
I'm finally ready to go turbo so I'm looking at 2 options. Banks complete system or Hypermax Pulse system plus intercooler.
I'm hoping guys out there with the intercooler can chime in.
I figure the money I save on not using Banks will go towards the intercooler, since I already have gauges and exhuast.
Dyno results would be great if available.
FYI: 87 CC Dually 6.9L C-6 (140K on motor) I tow trailers ranging from 16' tandemflat to a 35' 5th wheel triaxle on occassion and DD during the week.

the general consensus is that with the low boost supplied by the turbo on an IDI engine, the cost to power increase of an intercooler is not worth it.
basically put, an intercooler does not do anything with boost levels under 10 lbs, and the max boost you can expect to see will only be about 10 lbs. so for the added cost of the cooler, it just isn't worth it.

you used the magic word. hypermax CLAIMS a 30% increase in power.
they will say anything to make the sale. just because it is not true means nothing.
you can expect to see a 30% increase in power with the turbo and increasing the fuel flow rate. not with the intercooler.

I'm posting a link so you may further educate yourselves on the cooler. http://www.gohypermax.com/ViewItem.a...3-52afa136f526
They claim the same as bandwagon banks with there turbo kit, 50% increase. The intercooler will add additional power approx. 30%.
Anyway, I'm really looking for someone with experience using the Hypermax system w/intercooler.

The key words that you need to be aware of are "up to 30%". The unit will only make at most 10 pounds and I was blowing coal out the exhaust at the time. Don't waste the money on an intercooler. I have a standard Hypermax on my truck and it works just fine. I would take the money for the intercooler and use it to get better injectors and or a new pump.

You will make more power with 10 lbs. of cool air then 13 lbs of hot air.

the idi engine can only safely handle around 15 lbs of boost before it starts stretching head bolts, blowing by the rings and in general doing real nasty things to the engine.
remember, these things were designed to be run without a turbo. turbo engines are built different. with stronger head bolts and lower compression being just two items to consider.

They give you more volumn of compressed intake air. The cooler the air the more dense it is which means more oxygen.

that is not what i am saying though.
what i am saying is that for the cost of an intercooler, which normally runs around $900, you can do allot better things to get more power than the intercooler will give you.

On a wrecker we have at our shop...
We're currently running a 7.3 PSD intercooler, did it this weekend, and lost only a half pound (from 13 psi to 12.5). Dropped pre-intake temp 300 degrees and lowered EGT's by about 200.

I'm not concerned about price per pony, I know I'm limited on what I can do to get the most power from an idi without tear down. My thing is I already have the Banks Stinger system which came w/ exhaust and pyro (also already have boost gauge). So going with Hypermax I'm saving about $1000 on things I already have, which in turn could go towards the intercooler. Know see my position?
