Hello everyone, I'm new to DodgeForum and figured the best way to get trustworthy advice is to come here where people combine experience and know how to help people with their Mopar's. I have a couple things I would like to to get some advice on. I am doing the hughes engines plenum kit, keggar mod, full D.U.I. ignition, water pump, timing set the whole shabang while I got my truck apart. I am trying to see if anyone has used the Mopar Performance Double Roller Timing Set P5249267? If so how many crank keyway notches does it have? I've heard it has -4 0 +4 on the crank socket to adjust valve timing. I also read up that setting it to -4 will make significant mid to high rpm gains. This would be beneficial to me since I have gears and a 2200 stall. Any insight and knowledge would greatly appreciated. Thanks!

 

Welcome to DF
I will move your post to the 2nd Gen Ram section, The members there are very knowledgeable.

 

Yep. Mopar timing set with tensioner. I did not use the -4. I am using SCT tune.

Also, THIS is a cheaper alternative to Hughes plate. Save some $.

 

Thank you very much!

 

Well I've already got the Hughes kit in hand, but I've been reading everywhere -4 on the crank sprocket does wonders for the 99-01 Rams with mid through top end power. The tensioner is really required? Is this what you're talking about?

Adjusting -4 or +4 on the timing chain of a Magnum engine will do absolutely squat. Timing is controlled by the PCM.

Also, that chain is a good one

 

Advancing the cam (-4) will give more low end grunt. Retarding the cam (+4) is for top end power.

What you really want is a tuner... Talk to Hemifever about that, and make sure you are both on the same page about cam timing....

 

Adjusting the timing set changes the cam timing, not the ignition timing.

 

So just to be 100% clear, when I install the sprocket on the crankshaft, I put the -4 keyway notch lined up with the notch on the crankshaft stub then install the key? This will gain a small amount of mid to top end power coorect? I've already done the crank position sensor mod to advance ignition timing to a certain extent. I've just read a lot about guys retarding the valve timing to pick up top end, which is what I would like to do if possible.

 

This what it should look like when I install my chain correct? I want to retard valve timing to gian mid and top end. -4 should be lined up with the dot? And yes ignore the stamped dot on the cam gear. I just made my own dot to make the picture easier to understand. Sorry in advanc for my stellar drawing.
