5k D-shaped piston is 22cc

ok ill refine my numbers

Sweet , keen to know compression on 5k D-shaped with a 4kc head

so 4k with 4k head 9:1

4k with 5k head 14.88:1

5k with 5k head about 9.08:1

5k with 4k head and 9cc dish pistons 8.38:1

5k D dish with 4k head 6.87:1

5k shallow dish with D dish head 12.2:1

ask if you want to know any more head block config's

3k heads on 5k blocks? both types of pistons?

if anyone can give me the cc of a 3k head i can do that i don't have a 3k here to measure

What size gaskets are used in the calculations?

45thou thick and a bit bigger than bore size and are done on standard bore there are some factors that will make it different but it is within .25 of the amount of comp

 

For all you boost junkies!

 

A 5k block with d-shaped pistons and a 4k-c head with 8 psi of boost will give you around 10.6

Hmmmmm :laff:

man ive spent some time working out this crap eventualy gave up and let my engine guy sort it out

haha i am my engine guy :) since our buisness is hp racing we do engines have my own dyno etc

my engine guy is also my landlord has everything including an engine dyno in his back shed its a huge shed love useing his sandblaster and spray booth to make shit pretty been using his cnc machine and lathes alot laitly getting the 4y crank into the 5k block alot more work than i thought

that would be alot of work haha but don't 7k cranks have more stroke anyway?

+1

 

I got mine with a 4 speed for $150 off Sloth, just from asking around. Speaking of that, when I put in my 5K-ZE setup in a couple of weeks, can I enter this K challenge? :D The setup will be in a Ke55

 

That's a cheap 5k Ben. Be interesting to see how a blown 5k would go in a 55. I know how they are in a 1x well from the drivers seat of one I never got a chance to race my setup.(damn). Well now I got a r31 LSD and on the hunt for a kr42 "w" series box and it will then cop anti-lag launches!!! Forgot to pick up 4age main bolts from mate yesterday when I put together his forged 4agte short.

 

If anyone wants a quick leg up into a forced "k" Ke-1x I know of one that could be pried off the owner at a reasonable price.

 

Stu.

hey stu theres a w series bellhousing and box on ebay type 5k i think
