Hello Guys,


I will show the work i made this weekend.

Is for B18C Bore 81.50 CR 11.7, i dont have machines to test the flow or capacity but check the pics and tell me something :p

 

Looks good. Wish you knew how good your work "flows"

 

looks to me that it's been cleaned up and knife edge as far as i can see from the pics. the exhaust port exits looks big, did you gasket match it? looks like the roof of the exhaust ports been raised a little bit. Which part in the IN port did u spend the most time on?

 

I cant test the flow because i dont know if have this machine in my country LOL.

I only polished the Intake and Exhaust Ports with Knife edge dont open more...

The part i spend most time is around the valve guides because i dont remove them.

many thanks

 

Looks like too much material was taken off in specific places

 

You should concentrate more on the short turn than the guides on that head. altho theres still more work i would do around the guides. get intouch with someone that can get u set up with a custom vj and watch that head flow!! good luck

X2. At least the exhaust ports look a tad large.

I'd also check out your combustion chambers, cant quite tell from the pics due to distance and focus, but it looks like you have a few sharp creases around the valves.

 

intake looks like its gonna be to smooth and might puddle the fuel on the walls if you can i would try and rough it up a little and i would try and round the intake divider a little more and not keep it a sharp edge. just my .02 even if you dont change anything let us know how it does
