How tight can this engine be wound ?
can the gov be disabled so it can be reved up tigher ?

Mikey
 
Well if she will whine up a lot quicker i am all for it tons of work or not.
I didn't know if such a swap could be done ?

My plan is currently to swap in a set of 4.56 gears that should help things out alot.

Mikey
 
You're missing the point, Mikey. You swap in a set of 4.56s, and you'll whine (wind?) up quicker, all right... you will hit max rpm in half a block at 30 mph. Problem is, with my Chip and electronic IP, all you will see is my taillights after the first 3 seconds.

If you aren't going to look at electronics, then don't bother. You need to sink 4 or 5 thousand into your truck, change the gears, change the IP to manual, re-do the whole turbo thing, and then you will finally be almost as fast as somebody who spend $500 and 10 minutes, changing the chip in his '94.

You had a bad experience in a gasser. Get over it, or get another gasser.,, your 6.5 doesn't behave the same way.
 
I currently have 4.10 gears and the truck runs 80-85mph just fine. . .i rare run any more then 60mph so for me 4.56 gear will do what i need with out having to alter the engine any. . .

Right now my truck has 4.10 gears and runs 70mph@2500RPM in OD, with 4.56 gears my truck will run 70mph@2750Rpm in OD.

Which i am told is a perfectly safe Rpm for my 6.5-T and i shouldn't have to change a thing but the gears and correct the speedometer.

Now if you want a truck that'll run 100mph more power to yea. . . but 0-75mph my STOCK 6.5-T motor will tow anything your chipped 6.5-T will with 3.73s. . .

Now if i add a chip on top of the gears oh boy is this thing is going to Really fly $750 in gears $500 chip $750+500= $1,250.

Now i had been planning going from 7.50-16 tires to 245/70R19.5's which would put me right back to a truck = a chipped 4.10 truck. . .So i'm still ahead of the game. . .Keep in mind i stated my truck dosen't see much more then 60mph so as long as its within safe RPM range from 0-68mph. . .

So for less then $1,300 I would have 1 stout stump pulling 6.5 without having to swap IP's around, But thats just my thinking and a friend of mine who has had 6.5 for Years in his 85 or so 3500 single rear wheeler. . .

If you'll notice i didn't really respond to the above mentioned "swap your IP" statment

Yeah, I noticed... what I can't figure out is why you want to 'whine it up' faster?

Are you after more power? Better acceleration? More noise? Seems to me you're going through a whole lot of what-ifs to try and gain something... I just can't figure out what you're trying to gain.

As for the 'my truck will tow anything yours will' comment, not hardly, 4.10 gears or not.

Just curious about why somebody would so completely ignore the obvious. Maybe I'm missing something.

*on edit* Not that there's anything wrong with ignoring the obvious. I'll fight to protect your ability to do so.

Oh, and if you can articulate what it is you're after, I'm sure somebody here will be able to help you attain it. There are lots of guys on here that know the 6.5 trucks better than anybody you could find anywhere. Good Luck.
 
I don't really care who's truck will tow more.

Let me ask you this if i can make my 6.5 do what i want and turn it from a truck i hate ( Constantly cuss about ) into a truck i love ( which would then turn cussing 6.5s into praising 6.5s) dose it really matter as to how i go about getting from here (bad unhappy) to there (Good Happy) ?

Just Woundering

You didn't answer the question, Mikey. You keep talking about turning your truck into what you want, but you don't seem to know what you want.

We can't help you get it if you don't know what you want.

On the other hand, maybe that's the point.
 
One thing that hasn't been discussed here is mileage. Gearing it down will give you more towing ability but I can only guess what kind of mileage you'd be getting. By chipping you enhance the torque output and don't slaughter your mpgs.
 
I'm not going to answer the question "what am i doing"

I will ask questions from time to time get the help i need and when i am done i'll unvale my Rig and i'll give you the write up in full detail of whats been done and why it was done. . .

call it project "X". . . I think things will go much smoother if you just let me build project X with out explaining it trust me you and all the 6.5 guys will be majorly impressed when the X-factor is completed. . .

Lets just say its going to be Regeared to 4.56's and yes it'll be Getting your "CHIP" refused to do earlier as yes your right lets get over the past and move on. . .

be on the look out for "project-X" or the "X-Factor"

Mikey
 
ROFL.. well, that's a good thing. Now you have another problem.

you started this thread by asking how to disable the governor so you can 'rev it up tigher' ... your question was 'how tight can this engine be wound?'

You don't just need a chip. You need a custom chip. Tuned by an expert.

That's the only way to do what you ask. X-factor or not.

As for just asking questions and refusing to provide reasons, you do realize that there will be no knowing if your answers are correct, don't you?

This promises to be enlightening. I seem to remember an Arne Johnson quote from laugh-in that covers situations like this...
 
I know all the options and situations.
this thread really could be deleted if you want. . .Its no longer needed as i won't be needing any extra RPM this should all work within it RPM range just fine. . . the axle have been IDed the factory ratio 4.10 was identified. . . al of that ws done with out knowing whats going on ? so the rest of the project should just that simple. . .

Mikey
 
Sure. I'll leave the thread here though.

By the way, if all you wanted to do was ID the gear ratio, you could have just posted the RPO or serial #.

Or spun the tire while watching the driveshaft.

Then again, the hard way works, too, I guess.

These are fairly high revving engines for a Diesel, but go too high,
