OK I have been driving my 95 s10 with the om617 in it with a 98 s10 5 speed from a 4.3 with
3.42 rear gear. The problem is that the take off is far from good ( might get me ran over)
I have a set of 4.10 gears that I am looking to install and a set of 3.73 not sure what would be the best. Not looking for a race car just not to get ran over.
What is your thoughts on this.

Before i am told to check the ALDA I have check all of that and is working.
but I am looking to adjust the boost.

 

I'd say go with the 4.10 rear gears. If it ends up too low you can always correct that with slightly larger tires.

 

What is the thoughts on setting the timing up a little if so need info on the best way to
handle it.
Thanks Vette

 

Are you able to currently utilize 5th gear? I'd think 4.10's also, but I'd first find out what the overdrive gear ratio is in your transmission and then calculate the tire height to determine the RPM's in 5th. Everything I've read says the OM617 cruises best around 2800-3000 rpm's and I'd shoot for that at 70 mph for my use.

 

I use 5th gear now but the truck will lug down under 50mph and need to drop down to 4th gear to build any speed.I think I am just going to install the 410's and see what it will do.
I will have to see what to do about my speedometer,but 1 thing at a time.
I still would like to look at bumping up the timing a little to see if it would help on the bottom end power.

mark go here and they have a great article on it
How to Set IP Timing via the Drip Tube Method - Pictorial - PeachParts Mercedes ShopForum

also I hope fte chimes in here he set his timing at 28 degrees I think he said it starts a little rough but once warm runs good

 

Thanks Dennis.
How is your project coming.

 

When I bumped the timing up it helped the bottom end alot, not sure what tire size you have, but with 410's you need 28-30in tires to be in the sweet spot. You might be able to get away with the taller tire running 2wd with a more areo rig. Also turn the alda out a little.

 

This is a reg cab 2 wd with 255/60/16 I have adjust the alda but no were I adjust it I can not get it to black smoke. Would 28 degrees to much on the timing.
