Compression Ratio Q

Posts: n/a
for low boost 5-8psi i would say that stock pistons 10.3:1 will be good enough.. if your strapped for $$$ and ur running 10-12 a decomp. plate should be fine.. other wise when boosting higher i would go with 8.5:1 compression forged pistons..
always use the highest octane fuel you can get.. for the extra 10 cents a gallon gives you a better sense of security..

I'm gonna start from the very low boost and then try to higher it so there wouldn't be detonation.
BTW, OP where is your nice avatars with some boobies?

You can always play with octane and amount of boost you are giving till you hear detonation.
My avatar is gone because when Java upated to the new software all the pictures got erased and I didn't feel like redoing that picture again, plus I'm not going out with that girl anymore.

^^^ not for long? what do you mean? that it would be hard or there could be kaboom?
I'm thinking about running 5-7 psi on 8.8:1 CR (for a start)
I'm confused with octan numbers, here in Europe, we have different numbers.
All you can get on gas station is: 80, 92, 95 and 98.
I think:
80 - normal
92 - regular
95 - premium
98 - super
So I'm confused, now I use 95 octan and it may be yours 89 or 91.

How is low end on turbocharged engine with lowered CR to 8.5:1 , I've never driven any.
Is it the same as n/a Tib, better or worse?
