Turbo petrol motor normally has lower compression ratio than the same naturally aspirated engine would have. However, the turbo blows more air/fuel mixture into the cylinder than would be drawn in without the turbo, so it's a similar effect to raising the compression ratio.

Batman: OK sorry I thought turbos need high octane because they have high compression... I guess not?

 

It's just me being a bit pedantic. Because a turbo forces more air in, they lower the compression of the engine to compensate (as ultimately it will be much higher under boost).

 

But you still are likely to need to the higher octane fuel. What kind of car do you have? I remember being a high school in the mid nineties and a friend's Dad bought an A8 which had 220kW from its 4.2L V8 and thinking how amazing that was.

Compression on mine is 10:1 and turbo'd .. for 700cc of pure awesomeness 😁

98 runs well, torque app till claims the knock sensor is registering premature detonations (getting old like me perhaps? 😉 ), so seeing what 100 does.

I still have the injectors air intake to beef up but that all needs the rear of the car pulled off to get at .. unless I find a friend with super skinny arms but the grip strength of the hulk.
