Info on Woods TW408G Cam
Anybody know anyone running this cam? Talked to Bob Woods today and he said if it was him (with my scoot)he'd go with this cam and the Super King 505 carb, go with his valve springs and make 130/130. Now that's tempting but its also about $2000 or so........

RE: Info on Woods TW408G Cam
I don't know anyone using the 408, but i know a few that are happy with the 400. I talked to woods last week and he said i need the 400 for my glide with the heavy bike, me at 260, and living in the hills of Pa. I am making 112hp, and 119tq now with my 103 but i am going to cncported heads with the new cams, he also said to use the same cams when i go 113 next winter. It seemed to me the 408 was better suited for smaller guys and the flatland.

RE: Info on Woods TW408G Cam
A real big factor in picking the right cam is looking at how many degrees after BDC it is closing the intake valve and relating that to your compression ratio. To getyour static compression PSIin the sweet spot of 170-180, the valve should close later as the compression ratio increases to bleed off excess pressure. Also keep in mind as the duration @.053 goes up, the power band moves up into a higher rpm range. Gobs of HP after 6000 rpm is not very usable in real world riding unless you frequent the 1320 on a regular basis!
That cam needs a minimum of 10.5 to 1 compression, and has a very high lift that is going to require a strong seat pressure on the valve springswhich in turn puts a lot of stress on the whole system (cam bearings, lifters, rockers/rocker bushings, valve stems ect.)
Just my opinion but for a reliable usable driver, it is overkill. For a competative weekend warrior, have fun at the strip!

Decided to go with the TW400G, Wiseco 10.5-1 Forged pistons, S&S Roller Rockers, Stage III head work from Hillside Cycles, JIMS tappets (maybe GMR'S), going to stay with my SE44 carb and see how well we can get it tuned. Should be fun

RE: Info on Woods TW408G Cam
I just fired my bike for the first time today with the Woods 400 cam, did not go with the gear drive, gonna see how the new chain setup works. I have yet to dial in the tune, but no spark knock at 10.5:1. I think you will like the setup although I did go with the CNC Proted heads, but kinda tricky to get the squish right. All in all, I am pleased with the build. Once I get few more miles on it I will dyno for the final numbers. Good luck with the build, let us know how it turns out !
