Has anyone on here (DonF, Brad, Larry@ENDYN) experimented with different ring placements on a Honda piston? NOT speaking about moving the oil ring up and bunching the rings together to run a longer rod, im wondering if anyone in here has experimented with just how far up you can place the top compression ring below the deck height before you run into problems with the ringlands...

 

On normally-aspirated applications, I run the top ring as high as possible without breaking through into the corners of the intake valve relief's. This helps eliminate crevice-space between the top ring and the timing edge of the piston.
On nitrous and turbo applications, the top land needs to be thicker, so the ring has to go furrther down.

 

Depends on bore size.

 

How long do you want the engine to last before a re-build and piston replacement?

 

post a pic of your slipper skirt piston ...

Not a street motor. Something you could get 20-30 passes out of at the race track.

More heat transfered to the ring in a smaller bore setup?

 

On a 10 min. motor (drag) I would raise the top ring as far as possible, without losing valve notch integrity. Lose the second ring, use the XA oil ring, raise the pin, but not to the oil groove, shortest slipper skirt, and lightest weight. Probably a .708 pin and custom rod.

 

I woudl call John Sally at FSN Piston Company and ask for the "The Best Damn Piston".

Or call CP Pistons and tell them you want a piston for 20-30 passes and they'll come up with the rest.

 

Man you guys still use rings ?

 

Well he did say 20 runs, a little longer than your stuff. LOL

 

no no .. im talking about nascar and prostock engines ..

I just use shelf parts for street cars

 

Back to those "horsehair" rings you get from Jack? I like the new Chevy head P07 i think, have you seen many ? I like the I-E-I-E-I-E-I-E and Ex ports.

R07

 

 

P07, R07, whatever it,s still a Chevy. LOL Are the valves canted? Or just offset? 20cc's?

 

damn those things have like zero combustion chamber


.....now i know why the hemi was such a big deal.

 

What about on a street/road-race engine to run longer rods?

 

Who is the poor immigrant that has to port those ports. Must take 2,500 man-hours. Can't fluff and buff; wham bam thank you mam that like a Honda.

Must be some good Frank And David And Larry's over there.

LOL

Careful Mr. Master, thats a touchy subject these days.

 

Probably from Vietnam.

 

Du Ma!

Probably should have expected a comment on immigration from someone with "Master" in his username though, eh? Maybe it should be Masa of the Universe?

 

I bet he watches that Nickelodeon show Rocket Power

 

Yeah, red-blooded american head porters need to unionize and save one of the last great "American" jobs that effectively pay about $11/hr now taken away be 5-axis robots and cheap foreign labor. We need to start H O G (Headporter Organization Group) to preserve the strength of America.

What about the blue bloods from West Virginia?
