I just installed the D&D shift assister last week and I love the way my sled shifts now, but now the rpms are now down around 8150. I thought I read some where after you install a 2* timing your peak power should drop a few rpms but I forget how many. So my question is what rpms should I be shooting for now and how do I get it there?

Chris ( cmscat50) said should be at 8250 with a key. I have a f503snopro with 2.0 key, 102 studs,4 bulls eyes,360 mains, oil at 50-1 and a ods clutch kit. 52 weights epi yellow 165-310 primary and 60/49 helix with stock green secondary. I see 8250 all day long. Hope this helps.[attachment=63373:100_0092.jpg]

Sweet thanks for the help greenf503. Now how do I get the rpms to 8250? Can I just crank the secondary spring a little tighter?

What kind of speeds are you getting with this setup? More specifically...what rpm ranges seem the strongest, and at what speeds? just outta curiousity...

I have gotten to 97 mph on a hard packed road but it took almost 3/4 of a mile to get there. Full throttle at peak rpms is the stongest just like any other sled. It gets up to 70mph pretty quick after that it is pretty much done.

I would talk to chris first.He has helped me out so much. pm him cmscat50. He is always on here. I was at 8100 and went to a epi yellow 165-310. And my rpm's went to 8250. They say for every hole you go tighter you move your rpm's up 100.

I liked 8250 yes, but a bud of mine has all my F5 parts and only runs 8150 and it's a missile. So 8150 cold be ok...but I'd like to see no more than 8250.

IF you have a stock primary spring just buy a primary spring in the 160-310 range to increase R's a tad. I like to leave the secondary spring backed out as it keeps things more consistant. If you have to adjust slightly for conditions that's fine.

MAKE SURE your primary has no rubber on the outter sheave near the top. If it does you have to move the secondary in and this will actually lower R's even more as your belt is slipping.
