Zane Is also working with TS to develop a prototype speed box that will allow him to raise the factory speed limiter

I didn't think the OBS had a speed limiter. Rev limiter, yes, but I have never heard of a speed limiter. I specifically asked Cale about this when he burned my chip: I wanted a 'mom' tune for when she wanted to borrow it. Instead I got high idle.
Or is DP smoking something really strong?

It is there and Jody does not need a box to fix it. Test on my truck two weeks ago.

Oops, sorry. I meant DP as in Diesel Power.

 

[cowboy_dan]

Anybody know what the limiter is set at stock?

 

[Racer X]

Seems to be right around the yellow on the tach. 3400--3700? Stock my tach needle will flutter at about that point before a shift.

I think the limiter only applies in 4x4. My 96 has been gps'd at over 140 in 2wd. supposedly the 4x4 limiter is 112 or 114 i cant remember which.

Well if that's the case, why is there even a need for a box? Just wire around 4 hi so that 4 lo still works.

140!!!!!!!!!:ford:ullover::doh:

Damn dude a buck forty is haulin. Interesting on the 4x4 information.

Damn that is way to fast in a brick.LOL

 

[Short Bus]

ya its way too fast for that truck. It was frequently in the 120 range though.

I'm always thinking R.P.M.'s limits for engine stress. Read right by the speed. Luke would know for sure :tree:

 

[gregrob]

I dont think it was a hard limiter, rather that PW started getting cut back at a certain speed.

 

[Racer X]

That's right. Checked service defs. Rpm/speed is limited by reduced PW. Calibration dependent is all it tells, no figures.

If its the 4x4 think, then just unplug the harness from the T-case and it will think your in 2wd all the time. Since its OBS's were talking about.

That's what I thought. I'm still trying to figure out why that won't work. Possibly because some people won't want to get under and unplug it every time? Seems like a lame reason, but I've heard lamer.

 

[StrokerTurbo7.3]

ok so your saying my OBS will do over 120 in 2wd? I dont see how lol but I will take your word for it

 

[Short Bus]

yours probably wont. With your mods id doubt it has enough hp to even go that fast. If you have power, high enough gears and a nice flat road, these trucks will haul the mail.

 

[StrokerTurbo7.3]

now lets not make the were mods plural lol just mod.

I understand ya now though. I will be working on that though. Just need lot n lots of $$ that I dont have

 

[tjbeggs]

Isn't it just a single wire coming off the 4wd switch? if so just put a toggle switch inline. at the track flip the swtich and your good to go.

I know mine will do close to 100mph. That's with 4.10s, 31" tires & stacks!
Just looking at the speedo I would guess I was going about 100mph or at least very high 90s!
Not too shabby for an old non-turbo IDI.
