Yes, with dur 222/238 and high lift should be a pretty torquey cam for sure.

I thought Steve at GMR might have posted his results up somewhere when he was extensively testing this cam? I can't find anything though.

I can say too much compression.

9.3 corrected compression should not be a problem as long as you have access to 93 octane gas and you have a good tune done. Harley sells their street legal SE 103 kits and both of them put corrected compression at or above 9.5. Talk to Andrews (Gary Wallace was very helpful) and ask them what they recomend with the 48H

194CCC is more than what Gary advised for my 37's. I don't expect fuel quality to get any better, if anything look for it to drop again.

I'm at 190ccp with the 54's and had to pull some timing out to keep it from pinging in certain RPM ranges where the cylinders are really filling up good. All I have access to is 91, but I doubt even 93 would make a huge difference. I wouldn't want any more ccp with my current setup.

I'm 186.8 and all is well. Pulling timing [a good tune] to make up for too much compression isn't where I wanted to be.

Here's a sheet that Steve posted on another site earlier today. I believe it is a stock 96", 09 FLHX with TTS Mastertune, Fatcat and 48s. Very nice looking curve, or almost a curve, more like a table top; me likey.

I'm at 200 ccp on my '08 and have added 4* timing even in the 20% + throttle positions...and this is below sea level in new orleans...maybe the stock timing curve is less aggressive on cvo bikes

that's an impressive dyno sheet...do we have a replacement for the se255 as #1 lowrange torque cam?
