Truth^
I had my "as-cast" Serval dyno'ed when i 1st got it at HRI PowerSports in Texarkana,Tx and i got 74-75hp. ( I think i posted a sheet on here back then). Then Cam dyno'd the cyls , as i sent them to him, (no modifications) to get a baseline reading before porting. His dyno was within 1-2hp. He called me and told me what they dyno'd at, and i guess he was expecting me to freak out or something because it was "low". I told him what we got down here and we were within 1-2hp.
After porting he dyno'd it (sheet in dyno section) and i compared his results ( on 2 motors) to HRI and Dunetoyz in Muskogee,Ok ,and were within 1-2hp.
So im sure his dyno is in the ballpark of most.
BTW: Are we questioning the results 4 months in advance? ....
My thing is this : Who cares WHAT the numbers are,,what correction factor he uses, whether it reads high or low,,,, we are COMPARING numbers at the same time at the same place,,who cares what the numbers are.. we are just comparing. You could remove the numbers all together for all i care,,its the comparison ( overlay) of each pipes optimal chart that matters. Put 0 powers on there,its the graph overlay i'm interested in.
And i'll say this too, I bet no single pipe will do BEST at everything. One may come on sooner , others may give you more top-end,some more mid range, one may have a smoother delivery ,,but with the COMPARISON , you can pick which pipe will be best for what you need.
(example: I prefer Pro Circuits for trails and playing over Shearers any day. In the dunes , i like CPI, dragging, i like Shearers)
