Somewhere I had a formula for the intake temperature drop converted to HP increase.
I can't find my formula right now though.
Unfortunately, I just missed a dyno Friday night at the truck pull up the road.
Next year.

At the low boost levels our high compression IDI engines can tolerate, the power increase from an intercooler would be marginal. Intercooling might be worth the money for someone who tows and wants to reduce EGTs,reduce the heat load on the engine and gain a little mpg. Those are all good enough reasons in my book. I don't think you can do too much powerwise until you get the CR down (18:1, or at least below 20:1) get the boost way up there and add the appropriate amount of fuel. Dave has outlined the problems with doing that, e.g. hard starting, and you can lose some bottom end, off idle performance until th eturbo catches up.
Here's another idea... what about water/methanol injection? You get a little boost in power from the methanol, cooling from the water and the sytem can be set to kick on only at the specific times you need it, or manually. It's also easy to install...unlike an intercooler, which can be tough on the early trucks especially.... and relatively inexpensive. Call it a liquid intercooler! Set up correctly, water injection has been a boon to many.

Dave if you can find that formula that would be great! Most I've talked to lose about 300* intake and 200-300* egt. Sorry you missed the dyno.

Water injection will outpeform an intercooler, its been done since WW2. Though both will help performance, having a fine mist of water in the combustion chamber itself will, kill EGTs very well.
At the same time, the superheated water mist will expand when the cylinder fires, giving the piston an extra kick almost for free, so the overall thermal efficiency should also improve slightly.

Everything I've seen in this thread about water injection is true.
As far as filling up the tank... we use a 1.5 gallon tank for most of our customers. This will usually last them about a month before refilling... for the guys with the Diesels we can set you up with a 6gallon tank if needed. The installation of our kits takes no more than an hour. Also, you can run our system based on EGTs.
We will be running our Diesel kits on eBay this week. Also, we are running a 15% off special for Ford-Trucks this week.
If you have any questions feel free to call or pm me.

87dually, you are aware that you can buy the turbo kit from banks without the exhaust parts and pyrometer stuff you already have for a very large reduction in the price of the unit, don't you??
all 6 banks units i bought were with the exhaust delete, cause i made my own exhaust systems for the trucks. and the price went from $3200 down to $2400 each if i remember the numbers correctly. this was back in the late 80's and early 90's , but i would imagine they still offer the units this way.

I installed a 5.9 Cummins replacing the 6.9 IDI in my 84 F250....ran into clearence issues with the Dodge intercooler, so I've installed water/methanol injection system.
Have not any towing as of yet....so I can not attest to how well it works, but if it works as promised, I'll be very pleased.
Intercooler is the better option of the two but with the limited boost on stock 6.9's....I don't think it's worth the effort??

I was looking at Banks website.
One of their new intercoolers claimed a 200 degree drop in intake air temp.
I have not found my info about temp drop degrees to power increase percent.
For some reason I am thinking 10 degrees temp drop in the intake was good for 1% power increase.
So 200 degrees would give you 20% power increase.
That would translate to a 40 HP increase in round numbers if you could get the 200 degree max temp drop from the intercooler.
My thought is something like if you drive your truck a lot, if you tow a lot, if you have the money to spend, sure why not.
Yes it will run better, and you will have more power.
This is a 92 truck if I remember right, so it has been done before.

That"s too cool . Thanks Dave for the appetizer. Now feed us the main course. Is this yours? It looks like the intake hat is custom cast. Is this a preexisting kit ,available from from one of the diesel vendors? Or is it "one off " custom setup by one of our fellow dieselers?

The IDI's can benefit from an IC. With lower EGT's, maybe alowing some more fuel. BUT it depends on what IC you use. The PSD IC is much larger than we really need. A higher efficiency,smaller IC would do just fine. We're not running 30PSI + that the PSD's do.
Remember, that if you've got to crank up the boost just to get over the pressure loss of a huge IC and piping. Your just creating more heat, not more power. I'm contemplating a HIGH efficiency HKS, Griffon, ect.
