I too am very curious on the price point and how long these take to machine. Brian, What machine are you using? Also-Will this program fit into an EQ casting? J.Rob




I can only give you a price if you let me help with your next EM build

You know, I never thought of that but I'd have to sonic the floor/short turn on the EQ heads to see...maybe? These don't take too long because it's only the intake port.
They're done on a Rottler machine.




I would gladly accept some help but our engine for this year is pretty well done. Roughly how long for the 4 intake ports? What method did you use for the digitizing? J.Rob

Brian, if you'd like some EQ guienna pigs, I have a pair ready to ship. Uh umm, cough, cough...

Seriously, I'd be curious of the pricing with your VJ and valves, if the program was applicable to the EQ's

If you want to send them down, I'll sonic test them and then go from there. I might be able to have EQ send me a head to test...I'll let you know.

Intake MCA is 2.200 at the pinch.

Intake port poured right at 200cc.




Thanks

Thas kind of big.
Mine is 185cc with some more flow but stalls earlier.

Is there enough material around the guide to install new guides after the porting?

Still no price?

I can't price on here...they won't let me
Yes you can put guide liners in or use a shorter guide. I can get more flow earlier too, as much as 15 cfm at .400 and 10 more at .500 but the port is noiser and stalls real bad...Flow is only part of the puzzle...air speed, port shape, CSA is very important and it's really a balancing act of all 'dem.

Could this be done to a set of "J" heads? Would it be cost effective to install 2.02's and have a set CNC'd? Just curious

No, it's a totally different port design. Not sure if a cnc program for stock heads would be a big seller because of the cost factor....

What E-head stuff are you looking to develop CNC programs for?

SB right now...I might look at the Victor BB stuff since I have a head but the STD port version seems like a waste of time since everyone's building large cid engines these days....

Since I have a new set of the EQs on the shelf, I would be very interested in this as well!

2.200 pinch canīt support those flow numbers, should be 2.300. Anyway, these could be great heads for 408 with hp peak at 5900, or 360 with hp peak at 6700.

146cfm times 2.200 = 321 theoretical max flow...it will and does support those flow #'s.

You are referring to 350 fps air speed but that works only in local areas. Average air speed canīt be over 311 fps or port will be choked.

Anything over 350fps is not too good...that's the standard!
