The 99 uses different sensors, turbo, wiring, injectors and many other small modifications that help its power and drivability. Banks has an intercooler available that is more efficient than the factory one and would fit right on a 96. I would also recommend the computer chip, these (on the Power Stroke) make a huge difference in power. From what I've heard you don't need the performance exhaust as it doesn't seem to help any. Also if doing any changes I would STRONGLY recommend putting in a turbo boost gauge and a pyrometer. Nathan Bernard Union Auto, Inc.

But if there's enough back pressure to override the exhaust springs, then they will open. Ohhh... wait a minute. I see what you thought I said. Did I say that right? I wasn't saying (or didn't mean to make sound) that the exhaust springs were opening the exhaust valve. I'm saying that exhaust pressure can get high enough to over power the exhaust spring.

Fernandez" Subject: FTE 97up - Engine and exhaust braking There are excellent writeups of engine and exhaust braking at WWW.JAKEBRAKE.COM, the Jacobs company. In a netshell, here's what I got out of the Jacobs writeups: Exhaust braking works by restricting the flow of exhaust gases. The restriction increases the exhaust manifold pressure, which increases the pressure on each piston during its exhaust stroke, which slows down the engine. Engine braking works by momentarily opening the exhaust valve at the top of a piston's compression stroke. This releases the energy stored in the air compressed by the compression stroke, which would otherwise be mostly available on the power stroke. The engine slows down by spending its energy compressing air. = Ford Truck Enthusiasts ============================================== Send posts to: 97up-list Send unsubscribe requests to: majordomo "unsubscribe 97up-list" in the message body. ======================================================================= ------------------------------ Date: Thu, 21 May 1998 13:27:31 -0700 From: WiNk Subject: Re: FTE 97up - Engine and exhaust braking This makes some sense. The exhaust stroke is similar to the compression stroke but with an open exhaust valve to allow the exhiting of exhaust gases. If the exhaust port is restricted it is essentially a compression stroke, which will SLOW the vehicle down because the piston has no explosive energy to drive it down. Quite the contrary occurs, the restricted exhaust stroke acts like an air compressor attempting to resist the piston UPSWING on the exhaust stroke.Keep in mind the cam shaft and intake valve actions. Opening an exhaust valve at the top of the compression stroke is another ????? How does one accomplish this feat when the valve is up against a cam shaft and closed. Are you saying that we variable "valve timing"? I'm confused. Jose A.

There's some overlap in the valve timing sequence on some engines. With the exhaust valve closed while on the intake piston stroke with an open intake valve we would suck air and fuel into the cylinder. Then the intake valve closes on the upstroke allowing the gases to be compressed and fired by the plug. The mixture explosion drives the piston down, while both exhaust and intake valves are closed. Nuff of that sequence. Now for the exhaust brake! Are you saying that the "exhaust brake" somehow closes the air intake path thus braking the vehicle by creating a vacuum on piston during the intake downstroke? If this is the case then I can see that the vacuum caused by closing the air intake path would probably work. However, I see fuel without air entering the cylinder from the carburetor pump. A downdraft carburetor creates a vacuum at the gas jets, causing a sucking of the gas into the high velocity air stream to be fed to the cylinder. I'm just a bit puzzled over whether you are saying that cynlinder vacuum, vice cylinder pressure is used as the "exhaust brake". If your timing cylce view is from the vacuum side then the valve springs would come into play, however the only way that a vacuum could be achieved is by closing the air intake or having both valves closed on a downstroke of the compression cycle. If on the downstroke of a compression cycle with valves and air intake closed one would get a vacuum on the valves thus bringing valve spring tension into play. Then I wonder about sucking oil into the cylinder with the air intake to the cylinder shut off. I don't think that "vacuum" is the mechanism that is used as the exhaust brake enabler, though I don't know for sure because I haven't looked into the exhaust brake theory.

Fernandez" Subject: RE: FTE 97up - Engine and exhaust braking SIDE NOTE: Jacobs' WEB page(s) are really cool; they provide some of their parts and application guides on line! Wouldn't it be nice of all the {Chevy, Ford, Dodge, ...} manufacturers did the same? You could even print a new copy of the page that you just dropped into that big pan of solvent! One of Jacbos' on-line parts guides, 018060.PDF, shows how their Model 680A product attaches to the Mack E7 engine. This particular Jacobs product mates to the top of the engine and has little plungers for actuating the exhaust valves. Unfortunately, the installation manual is not on line, but it doesn't look like anything needs to be done to the head. The cam shaft, arms, etc., operate normally whether the brake is activated or not. When brake is activated, plungers depress the exhaust valves just before TDC, without interfering with the normal operation of the valve arms or cam shaft. -----Original Message----- From: WiNk [SMTP:invesys Sent: Thursday, May 21, 1998 1:28 PM To: 97up-list Subject: Re: FTE 97up - Engine and exhaust braking This makes some sense.

Casey" Subject: Re: FTE 97up - Break-In Period for the Super Duty F350 I picked up a new 1999 PowerStroke March 5th. I drove about 800 miles at changing and a variety of speeds before towing anything. I changed oil/filter somewhere around 850 miles. I then (after I put the new oil in!) pulled a 14,000 lb 5th Wheel from Chicago to New Orleans and back. I think I followed the suggestions for break-in procedure, though I haven't read them since then and don't remember exactly what was said. The next oil change was a touch early; I changed at 3658 miles, or about 2788 miles after the first change. The truck has not blown up yet; and, I doubt if it is broken in yet. Fuel mileage, when not towing, has begun to improve. I drove 400 miles when not towing--1/2 highway and 1/2 city--and, after filling fuel carefully, I calculated the mpg at 15.8. The miles per gallon when towing was about 8.55 over 2400 miles--all towing and at about 60-65 miles per hour. This weekends's 400 mile trip will be the first with a pyrometer, boost and trans temp gauge. For the first 20 miles when towing the pyrometer is at about 700 degrees (4-450 when not towing), the boost might be 10-14 (quite low when not towing), and the trans temp hardly moved--perhaps around 150-155 degrees max. But, that is very few miles (20 miles) to form any observations worth applying to a 400 mile trip. I am curious how the gauges will read when I hit some Colorado "hills." I'll do about 400 miles this weekend; maybe I'll know more then.

I would, however, give it at least a good 100 miles, if not more, while in Florida without the trailer. Don't change the oil until you hit the recommended first change interval, the engine won't "seat" correctly and you may end up with an oil burner for the remainder of the engine's life. This isn't common with today's engines but it does happen.

I am wondering how many of you are buying extended warranties for your new Ford Pickups? Seems to me that with all the electronic stuff on the new vehicles that ONE major repair after factory warranty period would pay for it. Has anyone heard of, or had experience with WARRANTY GOLD program? (good or bad) I recently bought 97 F-150 ext cab 4X4 loaded, with 5.4 engine. I love it so far. Haven't had any wheels fall off yet(recal) and the only whine I have heard is from me when I look at the payment book!....
