Upon speaking with Bob Wood,(NHRA Record Holder in Fuel Funny Car & C/Gas Supercharged, www.woodcarbs.com) for the second time during this business week, this subject came up, and I will quote, "Optimum for that cam is 10.8cr, but you knew that, Scott", why are you asking?"
I told him, and he laughed, and said, "You can only lead 'em to the water, but you can't make 'em drink." Guess that about sums it up.
BTW, that Walters program, which we too have had for about 15 years, (along with Cam Analyzer, Quartermaster, Quatermaster Jr, and Acellerator Pro, to name some) is NOT gospel, and has many gliches in it, as we have found. Don't believe me? Run a Lieneweber cam through it, or change the rod length on a given set-up.

ya,and im sure you guys can leap tall buildings in a single bound,turn water into wine,bla,bla,bla,i just looked at the cam specs and the computer backed my interpitations,and now the computer is wrong too,i guess his cams dont have to go by basic laws of how cams work.your statement about "leading them to water"reminds me of another one about the shepard leading the lambs to slaughter,im done on the subject

that cam will run at 9.8 not in my bike but im sure you can sell it.

 

Kirby,
There is no need to get upset over this, or take it personally, as that is not my intent to get under your skin, and wish I could think the same of you, as well.
Those cams really and truely kick some serious a$$, when set up correctly. The Walters program really and truely, does have gliches, as many folks know.
Back in the early-mid-nineties, we locked onto those grinds, as when we were searching for a combo that would rip, in 80" Evo's, when our first go with that 8 cam (Bob said 90/90) went 89 hp and 91 ft/lbs. (That bike is still in service, and has only had lifter replacement as routine maintanence.)
Pump gas, fast bike, happy guy. Can't ask for more than that.
You ought to give your folks the opportunity to try some of these on for size, sometime.
Who knows, they may like these as much as we do.
Scott

 

Optimum power and optimum "street" use are different subjects.

 

That is correct, and at this point, perhaps a quick phone call ,to Bob Wood himself, could easily clairify any misconceptions, myths, or non-truths in regards to this discussion.
I'm sure he'd be happy to speak to any/all. www.woodcarbs.com

Kirby, what cams do you use and at what compression do you set them at on a typical mail order build? Just curious.....

FWIW i have followed Scott's and Bob Wood's recomendations and have never been let down...

 

My point was the word "optimum", running the Woods 8 with less than intended compression would not be optimum and running 10.8:1 Compression would not be optimum for the street.

 

Running my Woods cam at "optimum" compression: Per Bob and Scott. Seems pretty optimum for street use to me.

How bout you Bagger?? No way you can be running that 9b at 11.4 on the street is there? Hows that working out for you?
