Slightly warmed up /4 motor applications...I'm thinking just about any design better than none at all....I'd like to metal spin these myself, however if I can get a good price on 8 from a fellow non-club member, I'll go that route (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif)

YUP... What everybody else said about the rounded edge.
He Paul.. I know you have made these before. Can ya make a clone of the TWM style rounded edge stacks?? Word is from the head porters I know, that is the correct shape (or close to it) One guy flows heads with the complete intake system attatched. He say's the rounded edge doesn't really give them much more CFM. But it does give them more uniformity of flow. Especially on carbs. Cause carbs need the velocity and proper flow charachteristics to get the fuel sucked out of the transition ports and the center anular ring effectively. They say it makes a great differance on transition from idle to mid or full throttle. (on carbs) Other than that.. I don't know any real data... By da way... take a look at those factory RACE ENGINES that were at the Pelican auction a couple of weeks back... (pics at PP board) ALL velocity stacks were rounded over. Paul.. You and I looked at em at the swap meet... Clayton |
