I have LQ9 Engine . I put new forged pistons and connect rods .
My project is :
LQ9 Cylinder ( piston bore is 4.030 , stock strock ( 3.622 ))
Vortech V-1 supercharger

My problem is :
- What is the best clearance ? with supercharger ?

please help me !!

thanks >>

 

Best clearance??? You mean compression ratio for forced induction?

 

Are you referring to quench?

 

The compression ratio is 9.5 .
I want clearance between cylinder and piston ( some person say 0.008 ) , I don't know what is the correct and the best , ( the boost mybe 12 psi or more >> )

the pistons specs is ( piston volume is -7cc , piston bore is 4.030 )
the cylinder heads is ( 71.06 cc )


thanks

 

So you want to know what cam to run?

 

no , I want best clearance >> in Cylinder

 

Thank You Guys
