I read of people changing the timing to 16*. Is that advance or retarted? Will that affect egts? I have mechanical ability and was wondering if I should attempt to do this? I had a local shop adj the timing but they dont know about high powered diesels. Is there a thread or a web page that shows how to do this?

Thank you

 

John take a look at this:
Timing FAQ

 

hey mr. Johnsjas, fill out ur sig! im curious to know what's been done to ur truck to make it 13 sec 1/4 since ur asking about timing

ps timing will decrease EGT's but u need a few special tools to get it done

 

I replied to that for you in another thread (what if?). It is also located in my profile, but since you asked,

220 hp injectors
Bully Dog stage 4 plate (Going to make 0 plate to replace)
191 DVs
4k gsk
5" exhaust
bhaf
HTS tranny www.htstransmissions.com
Super B turbo
Sure Grip w/ 3.55
315x75xR16 BFG ATs (looking into running slicks in 2 wheel drive)

 

higher timing lowers egt and raises cylinder pressure. with your little pump and in a racing aplication I would run 19* it should really help on the top end

 

I was looking at the table and are the numbers within the table a hp gain?

 

nice setup bro!!! yeah u'll like a timing advance...you're burn the fuel more efficiently and enjoy those 4 k gsks a whole lot more in those higher rpms with an advance...ur fuel economy will also improve

 

What tools will I need and how long should it take to advance the timing? How far should I go? I just read to go 19 but what if I go too much?

 

15.5 or 16 seems to be the most popular medium around here....u need a gear puller, a barring tool fpr the motor...a dial indicator...a special adaptor for the dial indicator for our pumps...i forget if there's anything else....

Snap-on carried a set for like 200$...most shops charge like 1.5 hours for it...only diesel performance shops will do it...a regular shop will almost always refuse due to legalities

 

the smaller pumps run better with higher timing compared to the bigger pumps. 19* will be better for your pump however higher timing equals higher cylinder pressure so the risk of poping your head gasket increases

 

WHAT IS SURE GRIP? ARE THOSE TIRES? IF, DONT THEY SPIN?

WHERE IN THE WORLD CAN YOU GET SLICKS FOR THE 3/4 TON TRUCK, WHAT RIMS AND WHAT SIZE????

 

johnsjas.....follow the procedure in the book, but not the timing figures. Download the Piers timing chart. It stops early but each .1 mm equals another 1/2 degree. Just do the math. You need to know the CPL off the data plate on the timing cover. There were a few pumps used for a given year and plunger lifts are way different depending on CPL number.

Miller sells the timing kit, so does snap-on. For the degree of accuracy needed I would get the right DV adapter and dial indicator and not try to fab one up or use a mag base. It makes the job alot easier. I would also not trust the timing pin as described in the DC manual. A dial indicator found TDC is more often than not a whole lot more accurate. And if you're talking about going to 19*, accuracy is one thing you want.

BTW, I'm at 19* and love it. I dropped back to 17 at one point and really felt a top end difference...went back to 19. Mind you I am only at 3K. I am moments away from 4K, and I'm sure the difference will be even bigger. Our small pumps like the high timing and I have suffered none of the by-products of high timing other than the good mileage and power!!

 

The sure grip is a posi system for morpar. 3.55 is the gear ratio and the 315x75xR16 are BGF AT tires.

I have seen some guys run slicks on diesels and I have a connection looking into different compounds and weight classes to fit my truck. Once I know more I'll let yall know.

 

Sounds good I'll try to decide what setting I am going to set it at (dont want to blow head gasket). As for doing the timing my self, I know a guy that works for Cummins that will do it on the side if I let him take it for a spin.
