That all depends on static compression. Mine for example, has a static of 10.1:1, dynamic of 7.99 and cranking pressure is 175 PSI even with an IVC of 70 degrees.
Change the static to 8:1 and that makes the dynamic fall and eats up a TON of cylinder pressure. So it's all relative.
Mulling through threads.......Rob, you mentioned in my thread that 7.5 is the limit for DCR, yet you are at almost 8. Does this mean that you are running aluminum heads?
