      You should get one or should've already had one especially with a Efan..helps charge at low rpms or idle,spins the alternator faster..

      Let me look through my notes and my collection of belts..i think i gave my belt for AC,over drive alt and underdrive crank away with the pulley when i sold it..wish i never sold it now,plan on getting another one for my big truck now that the supercharger is on the ranger..

      Im 99% sure i have a spare overdrive for your alternator. .if i find it you can have it for like $10 plus shipping (fits in a usps envelope) if not ebay has them for like $20,they will work with you stock belt so you could put it on anytime

      Have you checked your tps voltage?? May also be worth checking and setting now you got the bbk..also i cant remember what your running for a filter,if you still using the box or a open filter..

      But id suggest keeping the stock box,drilling holes through the bottom into the open space of fender well but not through the plastic wheel liner.a k&n filter.then replacing the plastic inlet hose with a metal one..from tb to maf connected to stock air box..then wrap the metal tube with exhaust heat wrap..

      Those ripples and crap in the plastic tube hurts air flow

      How do i check the tps voltage? I got a KKM filter. One of the first things I got for my Explorer. I've always thought about making a heat shield for my intake.

      Let me know if you have that alternator pulley. I'd be interested to get that

      Also if you have a warm air kkm then go ahead and make a metal tube intake..thats where your gains will be,very little..you can order piping online and make your own..just need a 90* and a 45*,then cut to size..of course a tb to pipe reducer and 2 couplings. One to join the 90* and 45* and one for pipe to maf

      Also i think a modified air box that still has a cold air inlet produces more power but many will disagree. .the under hood temps should reach ambient after about 15nph but ive found that not true

      Sounds good. Might also make a little shield near the intake

      Id just wrap the pipe in the fiberglass exhaust wrap stuff to keep the tube from heating up..id try and make a shield around the filter for sure though

      JD, what's the belt number or the belt length for this set-up? Ive got the underdrive and overdrive ordered.

      I also agree to reset your tps voltage with the bbk tb, I had to tweak mine and it helped.

      I also had the old ifab one many years ago that i paid a bunch for..sold it when went supercharged and then the one i made after worked better to me..
      Ifab..

      I did wrap these to keep heat down just cant find a picture of them wrapped.

      That's really nice, JD.

      I made a simple box from black sheet plastic and taped engine barrier material over it. Holds up fine. No idea if it's better or not but I'm with you on your thoughts on the subject.

      I prefer a dry element rather than K&N filter. I find the filter oil mucks up the MAS after cleaning and reoiling.

      A UDP pulley uses a 2.5" shorter belt..i cant find the belt number but the last 3 numbers on the part number is the size..like if stock is "900725" the belt is 72.5" long..so whatever the stock belt number is take 2.5 off from it,like "900700" that belt would be 70" long...ill try and find a part number for the stock 4.0 here in a bit..

      Old pictures of mine..

      Stock dayco belt..5060870=87"

      UDP belt 5060845=84.5"

      If to lose try a 5060840=84"

      If to tight try a 5060850=85"

      These are with AC and a smaller overdrive on the alternator

      I was thinking, if the intake tube got hot from lots of air passing through it wouldn't the heat wrap keep the intake hot and make it more difficult to cool down?

      Thats not why it gets hot..it gets hot from the radiant heat in the engine bay or the fan blowing hot air on it..thats why you see companies like K&N making intakes out of composite material or plastic but are straight smooth tubes

      Makes sense. UP will probably be first. I'm hoping to find an used Underdrive pulley from somewhere. Not having the best luck, might just have to get it new. This week I'll check the tps sensor. I have a feeling it needs to be adjusted because of the new TB. Not 100% positive on how to tweak it, but i'll have to read more on the thread you linked on how to do it.

      Hey you got lucky with the bbk,maybe your find a UDP but doubt it..only time people get ride of them is if they go belt driven supercharged

      The tps is pretty easy,id just get it close and if not then dremel the screw holes out so it can turn slightly. .normally if you just take them slightly lose you can turn it enough to get it very close,then tighten it down wile holding it at the voltage

      I've been looking at 4.0 mustangs near me that are being parted out with no luck. None of them have aftermarket parts on them.
