Piston Bowls

[DIESELMAFIAPER.LB7]

Interesting little fact:

These pistons have ~15% less surface area than the stock pistons and ~9% less than typical delipped pistons. If the BTUs of heat absorbed by a piston is directly proportional to the surface area, (it is if the chamber temp is the same) these will run cooler than stock.

This will be good to see results ill be doing a motor this fall hopefully an will use these if they work how we all hope they do

Just for sheer curiosity if/when my motor needs built what would a set of these go for? PM if necessary

 

[Fingers]

I'll cut them into your blanks for free.

Thanks for the info! :thumb:

 

[Trippin]

I know where to get the blanks........

Awesome keep it up :thumb:

TTT :woott:

 

[Jetty LBZ]

if these pistons work as planed will you make full sets with pistons and rods for sale?

 

[Fingers]

I've been away on a business trip. I hope to get into the shop and cut the rest this week.

how long until they find there way into an engine? i am very close to buying new pistons

 

[Fingers]

With luck, next week. Just don't know if I will have time to swap out the engines prior to leaving town again.

bummer i'd love to try these out

bummer i'd love to try these out

that makes 2 of us and probably more think my trans would go first thoguh

 

[Fingers]

You are welcome to try them. They are just untested at this time.

 

[hondarider552]

Any updates? How'd the machining go?

 

[McRat]

Very cool. :thumb:

The reduction is surface area might be worth quite a bit. You don't have to remove heat that isn't there to begin with.

Polishing the crown will also reduce effective surface area.

 

[Fingers]

The rest of the build with these pistons will have to wait till I get back home from this 3 week business trip.

Sidebar - I'm not sure the delipped are not better at resisting cracking than lipped.

Unless you can feed the temperature differences of the crown, and the strength at temp of the alloy, you might not be seeing why it's happening.

Not a lot of folk are cracking delipped pistons, but most cracked pistons are stock engines, which are the lion's share of the hotrodders. I do know that the lip is where the crack originates from.
