Not Ranked
Nascar
Hi again,
Just so you understand. My motor IS a Busch Nascar motor. It has one of the best combustion chamber designs around. That is why it puts out 473HP out of 274 cubic inches. That is a little over 1.7 HP per cubic inch. That is with only a singe 4 barrel carb. The heads are aluminum. That HP per cube would equate to your car putting out 910HP on a 4 barrel. Look at "View my Photo Gallery" on the left side of the page and take a look at the motor we are talking about.
There is no magic in this area. The best combustion chambers in the industry are probably the Japanese high performance bikes and they can get away with around 11 to 1.
Don't know how your motor is doing it but I can tell you that over 10 to 1 isn't going to hack it on 93 octane without some kind of help.
My opinion only but its based on a lot of different kind of racing with very good equipment.
Regards,
