You know, I've dynoed a whole bunch of these 110s. From 2500 rpm up the stock 255 cams are already loosing the TQ battle when compared back to back with
Andrews 54s or Woods 555s.
This is a typical dyno chart showing a Stage II X Pipe, woods 555 kit crossing the 100FT mark at 2500 rpm.
Looks like a 20 point TQ gain over stock at 3000 rpm too.
Over 100 TQ is also held to 5600 RPM. Thats a very, very wide TQ spread.
Stage II X Pipe kit, Woods 555 cams. Nothing special, stock heads, stock AC. I've never seen this kind of TQ with stock 255 cams.
SE 255s may be TQ hero's in 88s and 96s with low compression. That's about it. The only thing they do real well in a 103 or 110 is to ping and pass a smog test.
That big TQ dip you see in the stock run is partly do to the knock sensor pulling timing on a rock stock bike. Can't make TQ if your pinging.
Just my humble opinion based on consistent dyno results along with hearing stock 255 cammed 110s ping and detonate on my dyno dozens of times.
