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.

ok guys thanks for your help

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,

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

 

[Mbrooks420]

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

 

[speedinx]

i have 3.73 l/s how much do you guys think my exlporer wieghts i know it weighs 4000-4100lbs stock (according to msn) how much weight have i gained by adding 33's and steel wheels?

 

[spindlecone]

Hate to keep raining on your parade guy, but if you want real numbers, top off all your fluids, look in the yellow pages for public scales, get on down and get wieghed.
costs 3 bux in my area, that way you will have an exact number to work with, not a guess, is just my way of doing things because I am very ****

 

[Mbrooks420]

On a 4 door 4x4 i's say yor tipping the scall at at least 4,400. Stock.

 

[speedinx]

msn says 4072lbs stock, i looked around and there arent anyplaces around my area to get my truck wieghed, where did u see 4,400lb?

 

[Mbrooks420]

Was that the "Claimed Dry Wieght"?

 

[speedinx]

yeah

 

[huskyfan23]

Why does it really matter anyways? There are many more factors than weight.

 

[Mbrooks420]

When's the last time you drove it dry? Those fluids, your stuff, and of course, you, all add up.

 

[spindlecone]

Factor in ballpark 8lbs per gallon for fluids, you as Mbrooks says, the beer you may contain and do not forget, your 33s have a huge amount of air volumn.
That air alone wgts alot, when the tires get hot, the air wgts more, so remember your wgt will fluctuate dependant on driving conditions

 

[huskyfan23]

How do you know he doesn't fill his tires with nitrogen?

 

[Mbrooks420]

And isn't rotational mass 4 times as detrimental as static mass? Plus all dirt, crud, bugs and tar, and inevitable fast food, and empty big slam bottles. Don't mind me. I haven't slept in 2 days. Tonight isn't looking good either. : pillowgrasp:

 

[spindlecone]

If I were a Mod,(which i will be one day when I can pony up the bucks).
I would end this thread, is going nowhere

 

[speedinx]

how much horsepower and differece will a kkm intake and a 66mm bbk throttle body had?

 

[huskyfan23]

It's different on every vehicle. I'd say 10 max, but the throttle response you get is definitely worth it. Mods work together. The better the engine breathes the more hp you'll get from using the right mods.
