Low RPM governor speed

[Thewespaul]

That thing moves! If you’re ever in the area give me a call or text and we’ll throw the timing meter on there and get it right where it needs to be.

 

[Thewespaul]

So, the adjustments I made to the IP seemed to retard the timing quite a bit, it was running crazy quiet. I advanced the timing a bit more and took another test drive. This is the fastest IDI I have ever been in. Check out this video.l, I started in 2nd and went 0-60 in about 8 seconds. Not bad for a huge diesel, 4x4 extended cab long bed from 1991!!!

Thanks again for all the help Thewespaul!

What type of horsepower do ya think I'm making? 225?

At least 500hp. No I think around 225 is fair estimate

My tach redlines @3800 and mine will spin up to that.

Yes, mine wasn't right for some reason. The previous owner had a lot done to it and I don't think they did all of it correctly. Is yours a '94 turbo?

 

[Thewespaul]

It really depends on what application the pump came from and how it was setup by the rebuilder, very few trucks still have the original untouched pumps on them.

 

[Steven Donald]

It was supposedly the IP off of the '94 that he stole the rest of the turbo setup from. I believe him because he gave me the old IP from the '91 engine also.

Interesting, does it look like it had been apart for a rebuild?

After seeing your success with this repair I am honestly feeling a bit more confident sharing some diy pump mods that can be done to squeeze some performance out our stock pumps without spending big bucks on a built pump. Gonna look into making a write up for some of this if theres an interest for it.

 

[Steven Donald]

I would definitely be willing to guinnea pig that kinda stuff.
