Does anyone know where I can see some dyno charts where they only compare different cams? I'm primarily interested in SE cams but if you know of others please post directions. Thanks.

dont know if ide base too much on different charts,alttitude,temp,different dyno`s and just different bikes in general,find a good shop,go with their recomondations for their proven combinations for what your looking for and you should be fine,lotta dyno charts floating around that i aint buyin anyway

Sorry, dont have a link to such a site.

But 1-1.1 hp/tq per cube can be easily attained in a reliable well mannered street motor. Plenty of builders out there with 100's of builds over the course of decades to back that up.
Higher numbers are possible as well but usually will end up giving up something. Usually bottom end performance and rideability.

 

I'm doing either 255s or 204s this winter. I've spent countless hours looking at dyno graphs and numbers. I have come to one conclusion. They are very misleading. Seems hp and tq numbers can vary 5-10 with the same basic build. I think there are a lot of poor tuners out there.

 

Tom very well said also pro drag is correct all things must be taken into consideration.
altho it seems that a proven package will still out perform most SE parts .
i have seen more poorly tuned bikes then i have seen properly tuned machines that is a fact. even a good dyno operator will get the most out of poor matched parts. poorly matched parts will make a good tuner look bad.
SE parts are ok for doing when you are loking just for a bump in power they are also a little cheaper then after market parts and guys are running their parts all over the country.

i agree totally,a good shop will use the best & different parts for a good all over combination,SE stuff will give some power over stock,but its kinda "the easy way out".all the good aftermarket parts are all USA made,and better quality than SE stuff too

also shops will know what they like to use.
it all comes down to what the customer would like to suite their riding style and the budget .. most shops that i know will work very hard to get the customer what they would like.

 

FWIW,
www.woodcarbs.com has an EXTENSIVE library of dedicated dyno reports, with his cams.
I do believe that he has certain comparisons as well.

Check this link out. Many same builds yet different end results, funny how big a role tuning has on builds???

then there is always those "Happy Dyno's".... some just give better numbers than others.
