100% fact. But that friction is minimal compared to ring drag.
IMO it’s better to not use a piston with offset pins and a 5/64 ring pack and use a piston with a centered pin and at the very most a 1/16 ring pack.
The difference in friction loss between the two is significant.
Plus the...
Here's another vote for riv nuts, and I plan to seal up the edges with some putty-like material, similar to plumber's putty but made for cars. Of course I can't find the putty at the moment...:BangHead:
They don't perform they function and are only used because of rules, those engines would pick up a lot of hp if swapped to a 4 bbl. Could he stay stock 2bbl sure but if looking for more power it one of the most basic upgrades there is.
Garlits Museum had one of these in it years ago. Not sure if it's still there. A lot of cars are there on loan and rotate inventory of race cars. Always different interesting cars
