117 w/ 650 Woods cam dyno sheet?

[3 Little & 1 Big Dog]

I am concidering the folowing mods. Zero deck the jugs, woods 650 cam, BCT baffles, Oversize K&N filter. I am not sure but probably larger valves and for shure springs, 5 angle valve job with a throat and chamber blend and a Thunderheart ignition on my 2006 K-9. Does anyone have any dyno's with the woods 650 with stock or mildly ported heads? Are the TP boxes disaster at that lift? Thanks

Look at my pics and you should see my #'s. I have that cam, head work, bigger valves, XXX carb, Dyna Y2K ign, S&S heads though.

I had a 06 K9 with the same setup and rockers boxes work fine. Had 120hp/130tq. Ran great!

Same here 126 hp/ 129 torque.

Hey little, how did you decide on 650 lift cam? Is this a race bike?

[3 Little & 1 Big Dog]

I am looking for at least a solid 1hp and ft lb per cu in. I think that is reasonably streetable. I have built 1 400 hp small block chevy 400 cu in., 1 550 hp 400 cu in, 1 600 hp 468 big block chevy and 1 700 hp 522 Big block chevy. All naturally asperated and street driven. What I have found is that the streetability and reliability start to deteriorate quickly after about 1.15 hp per cu. in. I really will probably not have this engine over 6000 rpm and do appreciate the torque hp calculations and applications. I asked for dyno sheets so I could take a look at the low end torque numbers not the peaks. I know nothing about S&S cylinder heads. Do they continue to flow after the valves get about .300 off of the seats or do they die on the vine like the stock Harley heads. I do not have a history of valve guide and spring life with this kind of lift. The 256 duration seams reasonable enough though.

allot of those questions john sach could answer.

You need to call Bobby Wood. He will tell you exactly what to expect.

He was right on the money on what to expect with the combo I have.

does anyone know how big of a cam can you put in our bikes after you cut the jugs down to 0 deck without doing mods to the pistons? Just thinking

First you have to ask if you are willing to run your bike on something other than pump gas? Bigger cam= more compression. The woods cam need a minimum of 10.8:1 to 11.2:1 according to the spec sheet I have and really anything over that will require some fuel additive.

[HDLARRY]

Good info, I've often wondered how much compression was required for the 650 Woods cams.

I just got my engine back from Hillside Cycles NY with the 650 Woods Cam, bigger valves, guides, springs, port and polished heads, modified Super G w/Thunderjet, Thunderheart ign. and it's at the shop being Dyno'ed tuned by Monday. Scott Palmer told me my compression is at 11.3 to 1. I will have Dyno #'s by this Monday.

[barhopper]

Serious compression. So much for pump gas.

Not disputing what Al says in any shape or form here but I got the 650 and pretty sure my compression is lower than 10.5 and it runs pretty good.

[barhopper]

I have the 650 woods cam also. I am at 10.7 or so static comp. The more compression, the more pop I am sure. Mine runs great also. I can get pinging at times. I could not imagine 11.3 comp with pump gas, ping monster. Start buying 55 Gal drums of Trick fuel. Now 11.3 with Trick fuel and that alone with no other mods would make a huge difference. 11.3 will be hard on that motor in the long run. I bet it runs awesome and best of luck.
