ive been searching and have noticed alot of talk about the compression calculators being off. so i want to see if some of you guys can shed some light on my set up.

ls block
us itr 20 over pistons
b16 head

what compression am i looking at.

thanks in advance hector

 

did u look at the c-speed CR calculator? http://www.c-speedracing.com/h...c.php

 

yes i have. my problem is, so has everyone else that uses ctr pistons and now realize their compression is really higher then what the calculator states.

 

with that around 10.8:1 give or take

 

If you are using the ls crank, I would say closer to 11:1 maybe 10.9:1

 

10.9:1

Also depends on how much has been taken off of the block and head.
