Is there any way to make the computer in a 2002 3.0 let you go faster than 93 mph?

Why do you need to go faster than 93 mph?

 

[CarsonD]

because..... i want to drag race at the local drag strip, but would it still be legal on the road?

 

[Wicked_Sludge]

you can hit 93MPH in the 1/4 mile?

what have you done to it?

 

[koda6966]

That's what I was wondering.

It's got blue RACING stripes on it. Obviously it's fast now.

If you're drag racing a 3.0 on 1/4 mile, don't worry about going over 93.

+1 it takes me about 5 minutes to get moving that fast

I drag mine... You'll be surprised...

you can hit 93MPH in the 1/4 mile?

First off I thought the limiter hit at 97mph or maybe thats just the 4.0. anyway to answer your question. The only way to get above 93mph would be to put a chip in it. Not a cheap chip either. My advice is do not waste your money on a chip I would just swap in a 302 or something. Rangers unless modifyed for pro-street (RACING STRIPES DON'T COUNT) are not meant to go that fast.

actually, the speed limiter is triggered on ford trucks at 92-point-something. our speedometers just arent that accurate (the needle itself is several MPH wide), and a speed limited isnt perfect (its hard to slow an engine thats at WOT down smoothly enough for the driver to maintain control).

ive run my 3300lb truck in the 1/4 mile before and it runs...the 1/4 mile.

put it this way...i would need over 200HP at the wheels (not the stock 120HP or so) to enter a trap speed above 93MPH. you 2wd guys are lighter, but not by THAT much.

if you arent sucking giggle gas or boosted, you arent hitting the speed limiter in the 1/4 mile with a 3.0 (or 4.0 SOHC for that matter).

I have a friend that has one of those Chevy S-10 extremes with the 4.3. It's stock. I have seen him hit his limiter in the 1/4 mile. I would imagine the 4.0 in a 2wd would do it as well. Then again I do not know the differences between the 4.0 and the 4.3.

the 4.3 is a torque MONSTER. it makes the 4.0 OHV and SOHC look like soft little baby kittens. it made up to 190 HP and an ungodly 245ft/lbs of torque. by contrast, the 4.0 OHV makes a meensy 160HP with 220ft/lbs. even the SOHC is only rated at 238ft/lbs...but with more HP at 207.

on top of that, most of the RWD s-10 trims are lighter than most ranger RWD trims. i also have no idea what chevys speed limiter is set at.

but, those are all flywheel HP figures. your typical RWD drive trane will soak up roughly 15% of your flywheel HP (more for an auto). so even a SOHC ranger is only putting down 175HP at the wheels. a 2900lb ranger needs more than 180WHP to hit 93MPH on the 1/4 mile.

a 3.0 ranger is seeing about 125HP at the rear wheels (depending on year). thats good for about 82 MPH trap speed.

1/4 mile ET's, trap speeds, weight, and HP are quite accurately calculated from one another...so all these number are very close.

Wow. Thanks for enlightening me!! Thats impressive!
