I've been flying my RV4 for about 6 years now. I have a stock 180 hp Lycoming IO360 with a constant speed prop, Airflow Perfromance fuel injection, Lightspeed electronic ignition and one mag. I'm interested in getting a bit more horsepower out of the engine. Can anyone recommend any engine mods that can get me to 200 hp or so? Also, if you know of a shop that can perform the work it would be appreciated.

Porting and flow matching cylinders - high compression pistons -

What Gil said.

Add a Rod Bower ram air setup to the cowl also.

Good for an inch or more of manifold pressure.

Thanks for the info.!

I've checked the links. Looks interesting. I love flying my airplane, but I like tinkering with it as much.
