One day in February 2002, the Ford Truck World group took over Turbo Technologies of Tacoma Washington. We had a few trucks show up and wanted to see what the trucks made in the way of horsepower and torque. Well, you can see what my truck made. I think the numbers are slightly off since I had to do the test in 2nd gear vice in 3rd (which is the 1:1 gear) since I have oversized tires on the truck and I was fairly sure I was going to hit the speed limiter before hitting the rev limiter. So, take the numbers to mean what you want.

This is a nice close up shot of the front end. You can see the hold down straps that got a nice shock test as the truck hit the rev limiter (they got tested as the motor had the fuel shut off to the motor as the motor hit the rev limited, made for an interesting moment the first time I was in the truck). It shook pretty good as the motor had the fuel removed and reapplied. Nothing like seeing a 5500 truck trying to jump around.

Here is a corner shot out the front doors of Turbo Technologies. You can see the rear tires on the dyno roller. I spun that roller to 93 mph in second gear. Hmmmm, I wonder how fast the truck would actually go if the speed limiter didn't kick in at 107 mph? Like I mentioned before, the truck jumped pretty good as the rev limiter was bounced on by the engine. Thank goodness the rear straps held too. Those probably got the worst of the strain as the truck jumped, shimmied, and jived.

This is a shot of the side of the truck on the dyno. Hard to believe that those tires are 35" tall. You can also see under the front passenger door where I accidentally dropped the truck 2 feet on to the nerf bar when I was out 4x4ing once in Tahuya State Forest. The day the pictures were taken was the day I did that damage. Unless I point out the damage when you are standing in front of the truck, you don't see it. This image just happens to show it really well. The nerf bar has been straightened out for the most part (was much worse). The body hasn't been touched at all. Oppssss!!!!!

This is a nice shot of the modified air box that I am currently using. From the dyno runs, it gains nothing in horsepower, but it does seem to gain one 10+ foot-pounds of torque at the peak. Since I am after torque in Nukie, it does the trick that I want and for costing nothing to do, was one of the best mods that I have done. It was done by simply take a cutoff pneumatic tool and cutting off the cone portion of the filter box. If I had to do it again, I wouldn't cut it back quite so far as to provide some shielding for the filter should water get sprayed into the engine compartment (haven't done any water blasting with the truck in the woods since I did this modification). If you want more info on this mod, write me and I will tell you in more detail what it takes.

This is the printout I got from Turbo Technologies from my time on the dyno. RUN002 is with the factory air box (unmodified-Thanks Tom Colgrove) and RUN003 is with the modified air box (see above photo). As I mentioned before, the numbers seem kinda low to me. The shop wanted me to get into the gas "easy", so, these may not be truely accurate numbers (I did manage to have the pedal to the floor normally before 4,000 rpm). And with the oversized tires and not being in 3rd gear, I'm not sure how that truely affects the numbers. But it atleast gives me a baseline to go from for any future mods (so, what do headers truely give you? I may just find out here shortly).

I wish I could have gotten the MPG file of the rear tire (passenger side) going up to max engine RPM, but, it got damaged inside of the camera as we were standing around waiting on the next truck after me. C'est la vie. Some other day I will get the movie on my next shot at a dyno. Gotta love modern day electronics.
