airflow restrictions

From what I've read the stock OHV V6 is not a high airflow/high rpm engine due to the heads and camshaft configuration. Therefore, I doubt that reducing the airflow restriction of the throttle body or MAF sensor by increasing their diameter will have much effect. I notice that you have a throttle body spacer. In my opinion throttle body spacers are a waste of money on fuel injected engines. I suspect you would get better performance per dollar from upgrading the heads or exhaust manifolds instead of the throttle body or MAF sensor.

My purchase of an SCT X3 from James included a custom tune. I think it was worth the money just for the improvement in shift points and the instrumentation for engine diagnostics.

yea i want to get a set of headetrs with either a flowmaster or a good muffler. yes i had a sct programmer some years back & i agree, its worth it! im going to have james make me a custom tune also when i purchase the x4 from him.
 






Speaking from experience, it takes a ton of money and time to get marginal results.

I tried almost every trick in the book (and emptied my pocketbook) to get about 240rwhp. What I can say is that it was a fantastic driving experience and the kids are still driving it. It still starts on its own on the coldest of days and has been trouble free.

If you end up going with a M90 supercharger, I do have a spare wrapped up in the garage. Shipping might be a killer though.

Your other option after you get the tuner is a 422 cam. You can pull the cam and heads with the block still in the engine bay (The heads will need some valve pocket work to install the dual springs needed for the high lift/duration cam.

Sorry, but these v6 ohv's dont make power cheaply.

yea i mean im not trying to make a race truck or anything,lol. just looking for a little more power. yea supercharged would be awsome! yea the 4.0l ohv claims 160hp stock and 220 ft.lbs. torque. im just trying to get to maybe 200hp.
 






I'm not sure that headers will really help on the v6 ohv. Maybe open up the exhaust as the muffler is really restrictive. Maybe (Depending on local laws) have a high flow cat installed and the other ones removed. Build your self a cold air intake once the exhaust is opened up.

Tuning helps, if nothing else James firms up the transmission and it really helps it survive longer.

I did install a e-fan on mine, but the gains seemed to be negligible. What I did gain from it was ease of working on the front of the motor, as removing the stock fan can be a bloody experience). Also, at idle the motor was quite a bit quieter as the air movement noise isn't there.

Beyond that, you are really in to pulling the motor apart. The lack of aftermarket stuff makes it very expensive as you go further.

Hope this helps. Its just my experiences. Yours might be different.

I don't see how bolt on mods will net a 25% HP gain. Unless you bolt on laughing gas or a blower.
 






Its just plain tough to make a bunch of extra power out of a motor. Period. The V6 ohv is even harder. Some vehicles were de-tuned by the factory, and there is a ton of power to be found in the computer tuning, but this doesn't happen in the playground we are in.

Thank you Jon. I think we all need to be honest on the reality of making extra hp.

well i did remove the 2 bigger cats and put a turbo 2 muffler on. and i have a volant cold air intake system with a volant cone filter. yea im for sure getting the sct programmer!

right, i hear ya. i mean when they made these trucks/motors speed and performance wasn't in mind. so i know im not going to be able to get a whole lot out of it without spending lots of money. im just trying to do a little bit just to make it a little funer driving experience!
 






A M90 supercharger definitely will do that for you.

I have to say it brings so much low end torque to the motor its really fun to drive.
Just a thought :)

yea i will say one thing explorers have some torque! how much does a m90 sc cost?
 






Problem is, the M90 is cheap, but....
Lower intake (From rpcaster (http://www.bansheesupercharger.com) (Ron, great guy), injectors, belt routing, intake routing, misc fitment issues requiring a bit of welding (Such as coolant filler neck), high flow fuel pump, Wideband O2 sensor to go with the SCT tuner......

This is still less expensive than going in to the motor.

It was my very first experience with doing anything like this. Fun project.
 






BBK advertises 7-12hp gain from just their throttle body. I was thinking of bolting on a CAI, BBK, Headers, and Cat-back and calling it a day with performance mods. Maybe net 20hp from all that?
 






Remember, its advertising.
I can't say for sure, but it sure seems like a stretch. I sure do wish it was all true.

Or, maybe you see 7hp from 5000rpm-5500rpm. Not all that useable. I really think the 4.0 ohv heads choke everything so badly that they are the bottleneck. Small valves.

really, not much can be done unless they are addressed, unless you go turbo or supercharger and force air in to the motor.

yea probably a little more than i want to spend. i mean the sct programmer is costing me over $400.00. then by time i get a custom tune made.....
 






Keep your eyes out for a super nice Explorer V8.
It sounds expensive, but cheaper in the end, and very nice to drive.

Spending the money some of us are on our trucks labels us for exactly what we are....Crazy. I seem to be right in there.

yea i mean its my daily driver. i want to get me a mustang or something to build fast. but as long as im driving my explorer, i want it to be fun :D
 






I've never played around with nitrous. I have to wonder if it would be a reasonably inexpensive way to make some power once in a while. Im sure you wouldn't need to be squirting a lot to accomplish your goal. A small jet would give a great boost, and the bottle would last a lot longer.

yea i mean its the most bang for the buck. a 50 shot would be fine and dont think it would hurt the stock engine.
