Does anyone know what the final displacement would be for an F20C running factory 0.25 oversized pistons?

 

2009cc vs 1997cc stock

Essentially nothing... If you are that deep in to the motor... with 14.5psi coming soon... why not go sleeved? 14.5psi you 'll need it!!!

 

Thanks for that quick reply

Due to unfortunate circumstances I will probably have to re-sleeve it anyway

 

What happened John?

 

with that kind of boost, it is doubtful you will be able to run anything over the factory bore.

have you seen how thin the walls are between cylinders?

 

Sideways is on stock bottom end with 500hp... but I think he drives about 4k a year. His is still alive and definitely kicking.

Laskey says 89mm bore is wonderful for anything but a drag racer pushing 50lbs of boost. He has now done 3 - 89mm bores for boost... all successful!!!

Oxnard is not too far away from Earl!!!

 

You have about 5mm of meat between the cylinders with 89mm bore.

You don't need to be sleeved at 14.5 psi- speaking from experience.

 

Also running 14.5psi here without any issue on factory bore.
