[Fot] TR4 head flow rates

FoT, 

Does anyone have any TR-4 head flow data. I'm thinking of going to the big valves 

so I decided it's time to get smart on the subject. 



>From TeriAnn's website discussing webers. 

"optimum gas speed" for best flow was 325 fps. 



"this might explain a little why lots of times increasing the size of the inlet valves does 

NOTHING for the power and may even be a deterrent." 



I use the mikuni hsr45 smooth bores which flow at 237 CFM. 

I'm just trying to put things into some perspective.
