redhead, for sure.

 

Looks like she has scoliosis or a hump back ... bad camera angle / lighting

 

This thread shall now come to order.

From same thread:

 

So...less than a 2% increase when new...and then just like normal gunky valves after a few months?

 

imagine what they'd get replacing the old gunky spark plugs with brand new dimpled ones!

 

Probably would net more air than whats currently inflating your ego!

WI would keep the dimples reasonably clean. Generally if you have tons of carbon on the intake valve at that location something is not right anyway. Gasoline is a pretty decent solvent.

Having said that, is it really much better than any of the other ideas like swirl polishing and 3 angle/5 angle grinds etc? How do they get the dimples? I also wonder about the other properties of the valve. Is it structuraly weaker? Does the increased surface area mean more heat transfer?

 

She always looks spectacular in that show.

 

my question to hustler is why are you posting pics of your sister and saying shes hot??

 

1) The gains shown in the dyno graph may not be from the dimpling but from other features / shape such us an undercut stem

2) the other valve closeup pic in post #24 by Joe shows "ratchets", not dimples. Ratchets have been used to prevent backflow at low RPM with long cam durations.

 

Still not getting this whole Geo Metro thing. Almost as if someone convincingly argued, "Yeah gay sex is great!! You should totally take it up the but!"

 

Hey how about you stop bumping this thread without pictures of redheads..?
