This article is a good read with some general info on the mods one guy has made to his IO 550 to generate 750 Hp for air racing.

Its Continental engine makes 750 horsepower (559kW)—more than twice the stock rating—thanks to a pair of custom Turbonetics 76mm turbochargers (one for each bank), sophisticated ADI, and a system which employs spray bars to spray coolant on the cylinders. The hot-rodded IO-550 runs 75-plus inches of manifold pressure (3-bar of boost, or 25-30 PSI).

Tried and true method used since WW2 :toothy7:

Of course, if you put 30 psi (and the right size turbos) to a 550 inch big block GM engine it would make 2000hp.

just saying! :angel4: :stirpot:

"sophisticated ADI" come on....its meth injection. So cutting edge!! Not..

Love how "news" articles are most of the time recycled info for generations that don't know of the past.

Still a cool article and engine. It would make a mean, but heavy, engine on a boat!

Gator,

You need to make those same mods to your A/C engine and go run the hill for 5 miles. It would be cool to watch the results.

Gator,

5 miles of dry is a typical morning as is. 260 Hp is plenty to run the hill all day and I have no interest in running 400 MPH, so I will probably pass.

Ya'll seem to be missing a key point in the article, being CM guys I can understand. Besides the cooling air flow at 400 MPH, Methanol injection cools the motor from the inside and he is using evaporative cooling on the outside. A water spray bar works well in humid Florida, but it works extremely well in Las Vegas and does not require a lot of water to do the trick.

...and a system which employs spray bars to spray coolant on the cylinders.
