Hi all, got the tune done today thanks to Rods Performance in AL again. I'll try to keep this short, this is a 2009 Ultra Classic.

Setup 1. SE 103 flat top pistons, SE 255 cams, mild port/polish & cc'd heads 85.1, stock valves & springs, SEST, stock header, Jackpot slip ons, SE stg 1 air cleaner.
Dyno results were the blue lines 81.44 hp and 97.26 tq

Setup 2. SE 103 flat top pistons, Wood TW 6-6 cams, Wood +4 cam gear, mild port/polish & cc'd heads 85.1, stock valves & springs, SEST, VH power duals header, Monster ovals slip ons, SE stg 1 air cleaner.
Dyno results were the red lines 93.11 hp and 103.76 tq

Gained 11.67 peak hp and 6.5 peak ft lbs tq, but the big difference is the TQ carries out alot farther, at 4500 rpms the Wood setup made 13ft lbs more TQ than the SE 255's, and the Woods made the same TQ at 5000 rpms as the 255's made at 3500.

 

Thanks for taking the time to post. Amazing how much cams can make a difference. I may consider trying those cams in lieu of my HQ 575's.

 

ToddnVal, do you have more valve train noise than the 255?

 

The Woods 6 is a .510 lift cam, not a high lift. They are very quiet, and are actually the quietest cams I've tried.

The high lift Woods cams are the noisy ones, but they perform damn well.

I adjusted the pushrods like Bob Wood told me to and it's very quiet. I had the stock pushrods on the SE255 cams and had a little noise from them, seems to be quieter this way with the adjustables.

 

For some reason I was thinking most Woods cams were noisey due to aggresive lope angles. I have the Red Shift 577 and it will clatter from 4500 to 6000

 

So what is the adjustment difference? Zippers has a different method, bottom the lifter than shorten the push rod .100 I think?

 

What is the difference in the street manners? Thanks.

 

I've only put about 50 miles on it but it doesn't seem any different just cruising around. I haven't really been aggressive with it because I wanted to wait until I got it tuned, hoping to get it out tomorrow for a little ride. If you look at the dyno sheet the HP and TQ curves are pretty much twins up to 3500, the new setup just has about 2-3hp/tq more than before until after 3500.

 

How did you adjust the pushrods, I have Andrews 26 g's with screamin eagle adj. pushrods and have some valve train noise. I planning to re-adjust tommorrow. I took the slop out then tightened(extended) another 2.5 turns.
