Question New here, Intercooler Question

Hi guys, I'm new here. Nice to meet you all.
I have a 96 F250 TD 316,000 miles, I use to pull my car to the track. It has a Banks Ottomind, 3" down pipe and a K&N. Exhaust temp is running up to 1000 or so after the turbo on a long hill on hot days.

#1) I have heard that 1050 is as hot as I want to go after turbo. Whats your take on this? Sounds reasonable to me.

#2) I have seen a retrofit for a 99 intercooler on a 96. Would this mod gain me much power? Is it worth it? I would assume this would lower my EGT slightly, is this correct?

Thanks for your help, Jason

Depending on where the pyrometer probe is mounted in the downpipe you can expect to see a difference of anywhere from 200-400 degrees. If its right after the turbo outlet, 200 seems pretty fair. From what I can gather (different sources say different things) 1250-1400 degrees in the manifold starts to make the tips of the turbine flow and flattens out the vanes IOW fries the turbo. That all being said give yourself an extra buffer. I'd say 950-1000 at most after turbo. Most of the time I don't even get that high in the manifold on my 96. Food for thought.

Hello Jason: Banks states that 1300 is the max temp from exhaust to turbo and 1050 after turbo, I would never push mine that high, but you are a racer. As for the intercooler - the gain is 10 hp for every 3 degerrs drop in air intake tempature, and yes it should drop your egt. I just got home from a smog upgrade class at a local collage and the instructor was the ford diesel mechanic at a local dealership for years. I took some time to try and pick his brain a bit, he made the statement that the K&N was one of the worst things anybody can do - yes I asked why, he told me that the K&N will let enough dirty air in to wipe out the fins on the turbo and he has replaced many of them. We live in a farming area and the farmers drive off road a lot. Our local Napa store owner just came up to me about a week ago and told me Napa had developed a new air intake filtering system for Fords, he told me it almost matched the K&N but stoped the dirt. Good luck Mike OB

Thanks

Thanks fellas. It is always nice to get some other opinions besides a sales rep. so I figured the people here would have the know. The 1st Banks guy I talked to said 1300, when i called back for a separate question another guy said 1050. I believed the last guy! lol.
Anyhow I am new to all this diesel stuff so I listen to and appreciate any knowledge anyone wants to share. I personally dont like to learn my lessons the hard way!
As far as the K&N, I have heard the same thing but it was on there when I bought the truck with some 312,000 miles so I figure whatever damage could be done has been already lol. Besides the truck doesnt see much dust. So I guess there is some give and take when using one. Ever stuck your hand in front of the filter when the truck is idling? These things pull some massive air. I would hate to slow it down much. Thanks for the info.
I was actually wondering if a cone style filter would flow more air while cleaning better. The pics of the K&N cold air have this type of filter and the "kit" looks pretty simple to make. Whats everyone think?
thanks again guys, Jason

The K&N FIPK is real simple, I imagine it wouldnt take much to make. It consists of a plastic intake tube with a boot to connect to the existing intake plumbing, a sheetmetal box to go where the stock box was, and a conical gauze filter with a stud for a support bracket and port for filter minder in the end. I think I paid 250 for mine, not real sure though. I can put up some photos of my setup if you want.

Ill have to take the photos tomorrow, it's already getting dark here. I think it was worth it since I picked up a couple MPG. Itl make the turbo a lot louder, and its good for a little seat of the pants difference.
