What type of numbers did they say you'll be putting up?

 

From FM email:
"You will need a bigger throttle body no matter what 107 you do. I will recommend the SE 50 mm Throttle Body since it is the most cost effective, it comes with appropriately sized fuel injectors."

I would assume the 110 would require it if the 107 does.

 

What about your clutch?

 

If you're doing a 10.5:1 on a 107 with 777 cams and Level B heads, the 50mm TB is not needed. Regardless of what your email says it just isn't so. If I were going with the 110(or bigger) then yes I would upgrade the TB as well.

There's a ton of dyno sheets on their site to support that fact. The gains from the larger TB on a 107 build are marginal at best.

 

Not a good sign if they are telling people they need things they don't.

 

He recommended the 999-6A cams so maybe that is the difference?

Regardless of which direction I go, I have lots to research as I have no idea what the differences are between the various Woods cams, or any mfg for that matter.

 

Still not required.

 

Going to need the FM/AIM clutch

 

I was just on the Woods site and they do say for the 999-6 cam a 50mm TB is required. None of their other cams list this requirement. I'm not sure this is the right cam for what I am looking for though. I think the 555 or 777 with their broader band range would be better for me. The 999-6 sounds like it is more for top end performance as it does not really kick in till 3k rpm.

Where is the line for needing a clutch?

 

you'll definately need clutch at the very least stiffer springs, research the hell out of cams nothing sucks worse than putting in the wrong cam and not getting what you want as an end result
