If your not boosted and your at sea level what did you do to reach 103% I'd like to know realy I would Cause I'll do the same thing to my DE. I figure a stock DE uses about 90-95% V.e. I would like to get that numer up cheap. dude jesse is looking to boost so I told him a number with 100% V.E cause he needs to hit that and go beyond to reach boost. What did you do please share HELP(port the heads?)kiwimx3 wrote:First off Im going to clear the air My post was in reply to Fowljesse, as I had started it then walked away from thetrick69 wrote:alright you want to get technical I will need the cam specs on the intake valve sizes and the flow rates of the heads. But since none of us know this I can tell you without a doubt the best ball park figure is 260 cfm without a doubt. the math equation I gave has been used for years it designed for sizing carbs to engines I've used it for years. And since I'm a mechanic I would say It is accurate. If you want to argue more I suggest you google search how to find this formula. And if your so smart lets here your awnser.
laptop, I certainly did not read untill this afternoon all your posts trick, if you think the comment was aimmed in
your direction, it certainly was not, and a lot of the older members on this board will certainly back this up.
If any offence has been given by my inattenion to not using the quote button I do apologise.
For the record a DE head flows 230cfm. as tested on a superflow flow bench.
As for your other statements, more so the one bracketed above, my KLZE for the record flows @ 6000rpm
289 CFM VE 103% BSFC .492 HP 213 TQ 186 ( So I guess its not stock then is it? )
