FLOW CHARTS?
 

Does anyone know the where i can find flow charts for the 1st, 2nd, and 3rd gen heads? I might be wrong, but this guy i know says his 12v head flows more air than a 24v head????:humm: He goes to this shop just out of town to have all his work done and believs this mechanic is god...... IDK?? But he was arguing with me saying that his flows better than mine. I just want this for my own personal archive. My 24v runs his 12v down and he had them put about $3500 in parts on this thing, it smokes. Thats about it.

a 24v will flow more then a 12v head, thats why they switched to them. even ported and polished according to PDR a 24v still flows more.... all the p-pump dragsters run 24v motors...

And thats what i told the guy, but he still wanted to argue. I just walked away. I really want to find a flow chart to show him.

Your completely right, a max ported 12 valve stage 3 flows less than a 24v stage 1. The stage 1 24v flows 9 more cfm than the stage 3 12v and in stock form the 24v flows about 10cfm more than a 12v. Wish I had some charts for ya. But yea it seems like he's a lost cause. :D

do you have what total possible flow is Red???

The stock numbers on the head flows are 12v intake 143cfm exhaust 151cfm vs. 24v intake 156cfm exhaust 169 cfm's. So in theroy it takes a stage 2 port job on a 12v head to get close to a stock 24v head

Excellent........thats all he needs right there ........good job Red:ok1:

:ok1:

thanks guys, this is what i wanted.

:U:

At what vacuum pressure? as long as they were all done at the same pressure the numbers above are nice to compare to each other however they don't give you jack for real world # because we don't know at what pressure they were tested at.

pressure is simply the resistance to flow so the less resistance you have the better the flow is (less pressure)

these numbers that Red put up are just examples that the 24 valve head flows with less resistance than the 12 valver did

yes that is true but You have no idea if the head was flowed at 13" of HG or 29" of hg which makes the numbers somewhat useless for any math calculations.

If you ever wanted to choose a turbo for your truck and actually THINK(I know thats hard) about how well the turbo matches your truck as opposed to "well lets try it and see what happens." then the above # don't help much.

That was not the question,the question was what flows better,24V>12V,that's easy.

also true. But since I'm the only one that seems to care I'll shut up.

what about the CR heads, ive read the 05-07's flow the best out of all the heads?
