2.5 HP per cubic inch, How hard is it?
 

How hard is it to make 2.5 horsepower per cubic inch, at the flywheel? What would it take? Proven combos?

Assume NA? Lots of compression, lots of rpm. IE: pro stock motors. :drink: :drink: I think Greg Anderson is around 1380HP :eek:

How about some combo suggestions, cid, heads, cams, blowers?

Re: 2.5 HP per cubic inch, How hard is it?
 

We make over 2000hp in our blown injected 500ci+ Pro mod race car engines that I shift at 8000rpms , its not a matter of being hard to make 2.5hp per ci.
It all depends on what the application will be, for the reliability of a marine application to make 1250hp with 500ci or 2.5hp per ci she is on tilt with a ton of boost , and with the cam needed for that hp to ci probably not to user friendly at idol when docking!
I may be wrong as this is my first boat!
In ourTop Gun with 502s we just added AFR 335 cnc ported heads bored her to 509ci, JE pistons a small comp cams roller, etc with 7lbs or so of boost we now have 775 to 825 hp with a rev limit of 5800 rpms. We could turn up the wick a bit but I don't believe we would be on the bay to much!

The water ski racers have it pretty well figured out! I don't know much about their combos but typically they run 509 - 540 CI and injected turbo motors. Oh ya and they race for some pretty decent durations!! I believe these motors are putting out 1300 or so HP!! Not bad for an endurance motor!

Is this something I could build myself if I bought the right parts?

Re: 2.5 HP per cubic inch, How hard is it?
 

You built your motor didn't you!!! :p Please tell us more about that combo. I want to know more about the M2RACE heads as well. May be a good upgrade to the CNC ported Darts I am running. :D
