my first car

[4.0xplorer91]

hey guys,

i have a 91 ford explorer xlt 4dr 4x4, i had the suv for 1 year now and did some mods, i got a 2" spacer and shackle lift and 2" body lift, under that i have 32 m/t bfg and black steelies, but i need 30 more wheel horsepower,
these are the parts i found so far tell me if the horsepower seems right to you

performance chip 15hp
bbk throttle body 8hp

does anyone know any more performance parts i can get to get my 30rwhp gain!?!?

 

[jimbo74]

without some major mods 30 hp at the rear wheels is a lot... even with bolt on performance adders, and im talking all of them costing tons of $ you still might not make that goal.....

why do you NEED 30 more rwhp? if its because of the larger tires, i say regear, and this will make the truck perform better

 

[dman726749]

exhaust, open element air intake.......

Welcome

 

[huskyfan23]

MAF, BBK TB, Apten chip, Headers, Exhaust, Open element intake, and I doubt that would get you 30rwhp. Those #'s the manufacturers give you are BS and not measured in rear-wheel anyways.

ok i looked around on this site and these are the parts i came up with
kkm intake 5-7hp
75mm mass air flow sensor 6-8hp
bbk thorrtle body 7-9hp
thorrtle body spacer 4-6hp
performance chip 15-17hp

that is anywhere from 37-47hp but i also saw that explorers have anywhere from 15-25% drivetrain loss

so we will go with 20% that give me 30-35hp gain ...right? or will these mods be even less

 

[95offroadx]

do you already have exhaust because my exhaust added 8hp

manufacturer claims are flywheel power and are most often times exaggerated...... and drivetrain loss is probably closer to reallistically 20%

do you already have exhaust because my exhaust added 8hp

have you had that dyno tested? i highly doubt that an exhuast gave you 8hp, rear wheel or crank --maybe crank, but still seems unlikely

 

[95offroadx]

i had it dyno tested at a local shop that does tranimission work... stock power was 122.4rwhp and with exhaust it was 130.6rwhp

the only reason i can afford to do these dyno test are because i am friends with the guys son that owns the transmisson stop.. so after i get my kkm intake this week im going to have it dynoed again to see if that gives me anything

 

[huskyfan23]

Did you do the dyno same day? So a base run then add the exhaust and do another run?

 

[95offroadx]

when i first got my explorer it was all stock and had 85,000 miles on it and i dyno'd it and did 122.4rwhp and then i got my exhaust installed and pulled 130.6rwhp first dyno was on 8/11/04 and the second pull was 9/19/04 and i plan on having it dyno'd again this saturday if i get my kkm intake..

does anyone have a kkm intake and when they installed it did you feel a differnece and did it hurt or help you mpg

 

[huskyfan23]

I've got a custom intake, same thing as KKM for the most part. You notice a nice throttle response improvement, didn't notice mileage change, and I wouldn't dyno just after getting the KKM, might add 1 or 2 hp max.

 

[95offroadx]

does it sound any better?

do you think the i-fab one would give some more power?

 

[95offroadx]

and huskyfan23 is see your one thread about your hypertech chip ..do you like it ? what diffence did you notice with that? i was thinking about getting a hypertech chip in the near future

 

[huskyfan23]

It does sound better, real loud when barely pressing the gas (can't hear it over my exhaust most of the time). Hypertech sucked, got rid of it a year ago and bought an Apten, haven't looked back.

Why the magic number of "30rwhp?"

I wouldn't believe any of those hp numbers given by manufactures, and I doubt that you would see or feel any real performance difference with any of them. But with a combination of them, you should expect a decent amount of get-up-and-go. That increase may be 20hp or 40hp, but those are just numbers.

 

[BeauJ]

do you already have exhaust because my exhaust added 8hp

Mine added 39 RWHP!

 

[95offroadx]

did you get it dyno tested? and what exhaust do you have

 

[Robb]

That was sarcasm.

Dyno'ing a vehicle in reference to such small numbers, on different days, different temperatures, different relative humidities, etc etc etc is just about worthless. The only way you can effectively determine a gain from a particular mod would be to dyno the vehicle, install the mod, then dyno it again with no change in any other parameter.

 

[4.0xplorer91]

the reason i picked 30hp is because that would be the right amount to gain i will take more if it is there

since i already have exhaust i had a dyno test done where i got my exhaust installed and i got 17.5hp grain it went from 130.2hp to 147.7 hp and this was on all on the same day

 

[AspenX]

Like Jim asked in post #2, WHAT GEAR RATIO do you have with those 32" tires? If you go from 3.27s to 4.10s you will feel like you gained alot more than 30 hp.
