The higher CR will couse the turbo to spool up faster, but at the same time will increase your chance for detonation. so some other mesures may need to be taken to prevent it from detonating. 8.5 is still very low.

Im not going to any further into this becouse i dont even know what kind of car you have.

 

The more air+fuel you cram into your motor, the more power you make.

When you reduce the boost you can run by upping the CR, that may help you before you hit boost but once you are boosting it will hurt you.

Less boost = less air and fuel = less power

 

 

Slightly Lower compression will allow more power on pump gas due to the ammount of boost that you could run with it as well as timming. Lag, Who cares about that crap step on the gas and if thats not enough hit the 50 shot of N20 to wake it up and get that low compression beast out of the whole.

Good Luck sounds to be like a monster.

 

I have 8.5 to 1 compression with 95 pistons in my 1g. The spool up time is AWESOME. I have never seen any other car spool up so quickly. but I also have a 2g mas and many other supporting mods. If you have the fuel and air to add...do it.

 

I'm going to keep it around 50-1 trim......Maybe larger...

What is your lag?
btw, I can run 20psi on my 14b keeping the knock to a minimum on pump gas.
