no waves
more than a month without waves. two days relaxing at the beach without been covered by aluminum dust.
continued working on the F22 head, get some nice numbers despite of it's simple design. don't have a spare head of this one, so i+d work without damaging the head it's very difficult.
254CFM intake and 202CFM exhaust at maximum lift. OEM numbers are 234CFM for intake and 175CFM for exhaust.

F22 head
K20a head done and started a new project. F22.
it's a simple design head, straight port, without flow channels.
a speed analysis tells me that there is not too much gain on this head, no bebds to work on, no divider for the valve guide to channel the flow to avoid the divider...etc... very simple design.
OEM flows 234CFM at max lift.. achieved 251-254CFM. i don't have a spare head to go further on the design, so this numbers were gained on the customer head directly. no trial and error this time.
working on it, the shaft of the grinder broke .
254CFM design. worked on some high speed areas, not too high compared with the previous head i've done, k20A.

Which F22, new or old school?
flowed both F22 cylinder heads, the old and new design. Old design has a wider port entry, oval shape , and has more angle towards the valve throat. New design, cylindrical shape , less angle towards valve throat and also less port area. the new design showed more cfm through all the valve lifts , up to .4". at .4" valve lift , old design is close to the new one, but i think the new one has more potential so we are using this on the race car.

F22 and D16Y8
more work to do. F22 and D16Y8 cylinder heads and B16 intake manifold.
The F22 is for a race car with a low boost turbo setup.
