no, not looking for the cat crap that reads 8100-8300.....WTF does that mean?

i remember a dyno sheet from last year, and id love the see the peek and HP fail after peek HP is reached, this 2010 is strong thus far, just looking to get it optimally strong

D&D

Shows a Chart for the CRF800 HO and the peak stock HP came in at 7800 to 8000-ish? shaprly falls at 8200 and above. They have some info on a Y-pipe run and some other as well check it out some impressive #'s. just the Y-pipe they have adds 6-5 HP? impressive. Hope they can produce a can that will work and be lighter? The chart on the right below is really interesting. 192 peak HP. Wow!

im loving the first chart, seems to have a huge variance for RPM:beer;

the second chart has to be some magic Big bore as it says "901"

I think the 901 stands for the "901 superflow dyno" It looks to be a 800 cc mod engine? But the torque #'s look as though it would be a 900 class engine? It took a big hit in the lower end of the chart, But gained nicely above 6500 RPM. Bottom end must be a bummer, But then all hell breaks loose! The second graph looks to be a Bikeman setup?

The 901 is D&D's BB for the 800. I have heard that BDocker had a rg TM8 with the 901BB in it that was the sickest sled on the hill. Next years upgrade for the boosted sled i hope

SLP has a dyno chart posted on their site. It shows the stock peak hp right around the 8200rpm mark. The peak hp with their new pipe set is also right at 8200.
