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???? 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.

 

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

 

 

thanks guys, this is what i wanted.
