      howdy y'all first off this is a great site(just found it) ...........but how hard do you think it would be to get my 91 explorer in to the 16's?




      by the way i have a 91xls explorer 4x4 wit 3" body lift 2"spacer/shackle lift with 33's and i think 3.73 gears maybe 4.10 bought the lift off ebay and the wheels and tires from a local tire store, i havent done anything in performance yet,

      what is a nice loud exhaust that adds power?

      Do a search and you can find many different performance mods to do to your explorer. If you think you have 3.73 or 4.10 gears, you have 3.73s b/c the 4.10s were only available in 95+ I believe. You can go to your local exhaust shop and get a Magnaflow, Flowmaster, etc. exhaust made for about $210, depending on if you get tips, etc. You can also add a KKM intake for about $90. You can add throttle bodies, mass airflow sensors, and some other things. Do a search for "throttle cable mod", it's a free mod that gives you better throttle response. There is also a supercharger made(IDK if it's discontinued or not) for the 4.0 OHV. Just do a search and you'll find a bunch of stuff available.

      BTW - Welcome to the site. :)

      Check the white tag on the drivers door jamb for your axle code. If you have a 3.73 then the code will be d4.

      There is a 2nd gen on Turbo in the 10's.

      I have my 01 4.0 S0HC best at 15.9, Naturaly Asperated with Apten Chip, KKM intake, and Gibson Exhaust and I have 4wd.

      Anything is possiable. I would say you should be able to get there without a S/C. However, it might be quicker to use a S/C.

      You might gain a full second quarter mile if you ditch those 33's. It's a start.

      how much horsepower do you think i would need to get my rig in the 16's?

      heres the parts i found
      ifab intake-15hp
      70mm maf-8hp
      66mm bbk thorrtle body-12hp
      sct superchip-15hp
      heddman headers-10hp
      flowmaster exhaust-10hp
      that equals 70hp

      so i should have around 190hp at the wheels it that all i need?

      At approx 4800 lbs, you would need at least 215 RWHP to run mid 16s, and a perfect launch etc, the numbers you post above are manufacturers data.
      They do not exsist in the real world, good luck

      well stock explorer has around 120-130hp and the wheels and wieghts 4100lbs
      and runs low-mid 18's
      after you mods you wiegh around 4300lbs
      i have flowmaster 40series muffler and 2.5" piping and i gain aleast 8hp

      so you need 50+hp (guessing)

      Go Here, www.battleoftheimports.com/classes/battlecalc.htm
      You need to know your exact wgt (wet) and factor in the drivers wgt as well

      With all those mods you'll be able to reach the 16's. Just remember whatever money you put in the engine you'll never get back.

      Experiance and 400 bux worth of dyno runs and fine tuneing, granted my engine is diff. than yours.
      Unless you do some internal mods, all the boltons in the world will never get you 70 H.P in your OEM N/A engine, note I said N/A.
      Headers on an OEM V6 do little if anything.
      I think if you went with an open intake, a less restrictive exhaust, a chip or flasher tuned for premium gas, and ran Syn oil in your entire drivetrain, 25-30 H.P is realistic.
      Of course you could run nitrous and get an instant 70H.P.but thats a whole diff. can of worms, have fun. :D

      The MAF should be added after all the other bolt-ons, and at the most the noticeable difference is minimal, but every little bit helps.

      Dude
      Your grasping at straws, Ck your state emissions rules about the cats.
      You can do alot with some engine upgrades, just do not believe all the aftermarket manufacturers B.S.
      If you were to get 20 H.P. with boltons, with your engine thats a huge percentile diff.
      M is abosolutly correct about the MAF, it will compliment and finish off the program to a very small degree, is only so much you can do without getting into the engine.

      Mbrooks420, that "d4" you mentioned would indicate a LS rearend. The letter in a Ford axle code usually means a traction lock differential.

      The 33" tall tires probably are slowing down that 91 Explorer by a second in the quarter mile.(The much larger rotating mass is much harder to accelerate). Change the gear ratio by a ratio of at least 33/29, more if acceleration is more important than gas mileage.

      Test it with stock 29" tires to see how much the 33's are costing you. Good luck,
      Don W

      And for every 100 pounds of weight you pull out you gain .1 second in the 1/4, so don't carry unnecessary weight/people when you run your 16 :D

      A non LS 3.73 must be super rare. Of all the Explorers, and Mounties I looked at none were 3.73 open.
