Here are a few old post links talking about stock dyno results for anyone that cares
I dyno'd my truck. I wanted to get some real numbers before I start messing around with the engine. Though some of you guy would be interested in what a stock 5.0 would put out. Dynojet Max (RW/FW)HP: 162.9 @ 4290 rpms Max (RW/FW)TQ: 225.7 @ 3740 rpms Estimated Fly Wheel Horsepower: 209...

I took my X to a custom dyno tuner in my area, actually the best in the New England area and they strapped my bad boy down for a days fun. http://www.nedyno.com/ The owner, John was awesome- a real car buff just like out of the Car TV shows like Rides, Horsepower TV, Truckin etc... He had...

Explorer Express Dyno
Hey guys, I went out to beautiful Napa California this weekend to do some fine tuning adjustments on the Explorer Express X-charger kit. I already do the tuning that comes with the kit when you purchase one and Dave wanted me to fine tune a few so that we could ensure everything was...

Well I had my X in a different shop again for a dyno run. This time I installed a new 190lph fuel pump and assembly. The shop drilled a hole in my exhaust tube so they could accurately measure a/f ratio. I am told this is the best way to measure as opposed to the sensor in the tailpipe. It...

Hey guys, We had a few guys show up and had some great results along with some great learning experiences. The biggest was from using larger TB's, headers, and MAF's but that will come on down the post. First the constant vehicle to begin from was Aldive's truck, Al, 99' Explorer...

That first linked thread is for a 302 Ranger, he called it a "It was a 2X Exploder.... Now a part time 4X ranger." It says 100k miles engine, a baseline run, safe to bet it was virtually untouched for the swap, and could have had many stock original parts(plus/wires/O2's). I take that from the limited and poor wording, vocabulary, and lack of detailed results or details about the engine or swap.
The other threads are all about SOHC V6's, most that made 180rwhp or more, and I recall Al getting very close to 200rwhp.
The flywheel estimates are useless, please everyone, stop posting those or guessing at those. Only wheel hp matters, not what the engine makes but doesn't reach the wheels. It doesn't matter if the engine has 300flywheel hp, but just 210 reaches the wheels in a chassis dyno test. Today's cars are still rated in wheel hp, none are flywheel hp. Actual dyno tests alway come in a little under the ratings, OEM cheats by leaving off the accessory belts, and tests them in 2WD versions instead of AWD etc.
I don't accept that the 302 Explorer is a 160rwhp truck in AWD form, unless it's far out of tune. Tons of examples now need new plugs and wires, O2 sensors etc. But nobody should baseline an engine in poor condition, and post those mediocre figures online.
The actual computer tune should also be adjusted prior to any baseline testing, and nobody does that either. I'll get to my 98 eventually, and it has 225k miles now(trans is hurt(undriven now)). I will have the PCM re-tuned before every dyno test, including the first baseline test. I too want to know what a decent exhaust is worth. But I have no intention of buying, or installing 1.5" headers, just one muffler, or tail pipe, or use any section of an OEM cat pipe.
So in my opinion, the mild superchargers(6-8psi or so) that have been installed on the 302 Explorers, in AWD, should make close to 250rwhp, and likely under 275rwhp. That's with a good state of tune engine, and the PCM adjusted for A/F ratio etc.
