Intercooler question
I have a 1993 F250HD, GVWR 8,800, 7.3L Diesel with a Banks Sidewinder Turbo, E4OD Auto, 4.10 Axle (35), 4x4, Super Cab, Full Size Bed, 265/75R16E. Eagle Aluminum Rims, 125K miles. I am looking to install an Intercooler on my truck and am wondering if the Hypermax 7.3L Pulse Intercooler will fit and improve the performance of my truck?

It should lower your egts but what I've been told on hear is that an intercooler isn't realy needed for these engines and isn't cost efective. Dave S. doesn't even run one on his built up motor. I'm not sure if the ducting would line up with the banks kit but if you look at pictures of the hypermax kit compared to where your turbo sits it may give you an idea. Or you could try calling hypermax and seeing what they say.

The main reason I don't have one is I am out of room for it because of my plow bracket and the fact I have AC.
No more snow than we had this winter, the plow bracket may go.
Then again, no more than I use the AC, it might be the better thing to go.
Driving in very cold temps does tell me I could use one.

Dodge added an intercooler to the Cummins halfway through '91 strictly for emissions reasons. It didn't add any performance but it's not very thick. Banks makes a larger one for these trucks that does add some performance.
Much like a radiator: size matters.

I know ATS makes one for their kits, includes Ducting to route it under the A/C Compressor, I know A guy who had an older Truck with A/c on opposite side, he made all his own pipes and routed it under A/c compressor.

Hypermax sells a kit for your truck. Look in my sig for links to my IC album. I have not seen EGTs >1050 with the DPS turbo cal pump maxed out and the stage 1 inj. Im glad I did it. How much did it add to power? I dunno, I added it at same time I did turbo.

Nice setup. What sort of boost and at what RPM are you getting out of that? Don't suppose you ever had it on a dyno?

Thats probably where I am, but can't be sure because I never go as high as 2800. Thanks for the info, now I know where the hypermax lines up against the rest (seems to me there is no difference between brands). It wouldn't supprise me if you and I have the exact same turbos, only mine has the ATS turbine housing that has untegral inlet and outlet ports for the Y pipe and downpipe. I found some info a while ago that showed some larger comperssors for the T4 series turbochargers, I'll see if i can find it again and post it.
I would really like to get a bigger compressor wheel/housing for my setup because i know there is the room for it, and by the looks of it you have some extra space under there too. 10 psi is far from what our diesels can survive
. My understanding is that the system that was used on the OEM IDI turbos has the same compressor, but used a smaller turbine to get the velocity up, my logic is that a larger compressor should have a similar effect, but with a higher flow potential.

Found it.
Blouch Turbo Inc. - Our performance turbo upgrades and rebuilds
What I was thinking is to take the compressor wheel and housing off this turbo and bolt it on my T04B turbo, assuming it would fit. I tried Emailing to find out, but they never got back to me. They have a wide range of turbochargers in the T4 family, if nothing else its a good source of info.

Where are people getting these stage one injectors? I've looked on DPSs website and they still say coming soon?

Actually thats a complete turbocharger, but still pricy. My ARP studs could probably handle 20 PSI of boost, and since I opted to shave the pistons off by 20 thou, maybe a bit more boost. What I'm really after is more boost below 2000 RPM, if that means a LOT more boost above, than I can live with that 
. I still have a great deal of homework do do before I can really have a clear picture on what I need. I know very little about turbo theory right now.
What I do know is that my current setup is not giving me the optimum that my engine is capable of, especially with my tall gearing. Overall, there just isn't enough boost over the entire range. After about 5 psi, the smoke starts no matter the RPM. As I said before I could probably get to 10 psi, and I have been as high as 14 psi before the rebuilt (fuel screw close to max), but thats with a lot of smoke and wasted fuel.
