Setting pump timing

[mcandies]

I just had the transmission upgraded with the DTT 89 tc, clutch update kit with billet piston, and MagHyTec DD pan. What will setting the pump timing at 15 1/2 - 16 degrees do for bottom end performance on my 98', 12 valve?



Is this the same as setting the engine timing?

I remember reading that advancing the timing will result in a loss of low end power below 1600rpm... . but I doubt it's enough to really kill it... .

The top end power and overall drivability of the truck will be much nicer with more timing, though... .

Mines set at 15. 5 - similar trans and the driveability is Great.

I had mine set up from the stock 14 degrees to 15. 5 degrees. It was not a big adjustment and it really didn't do much for the engine performance. I didn't notice any change except that it sounds like a big diesel when it's idling. Some people that I work with asked me if I did anything different because they noticed the change in the engine when I idled by.

Can't believe you missed your shot Matt

No GSK. Bad Boy. You didn't tell him to get his GSK. You're slipping.

Yea what he says, get the GSK, 3k version at least, you will like it and so will your transmission.

I'm slipping almost as bad as my OEM transmission!!

If the thread had said anything about a GSK, THEN I would have stepped in.

My worldwide crusade to have every Bosch P7100 equipped engine cranked up with a set of Piers' governor springs continues... .

Matt, I wish you would slow down on your crusade. Now I can't get a gsk from Piers cause your crusade has worked so well!

Oops!

Well, even if the wait is a bit too long in some minds... . it'll be more than worth it in the end. I lived for 7 months without one..... I'll never drive a 12-valve without a GSK ever again.



Matt - The crusade continues.....
