Power curve

Post by highlandhovercraft » June 15th, 2012, 12:21 am

I have a 1999 Subaru Forester (Japanese import). It is 2.0ltr non turbo and as far as I know totally un-modified. From the limited info I have managed to find, the engine is around 134 BHP. I need to get a power curve for this engine so that the gearing can be worked out for the prop & lift fans. The nearest rolling road to me is over 200 miles away so not an option to trailer the car to a rolling road. Surely there must be some where online that has the power curve for a standard non turbo EJ20 Subaru engine. Does anyone know where I can find a power curve for this engine?

There are a couple good Subaru forums on Yahoo Groups that have a fair amount of information on the various Soob and Geo engines, where they're used in homebuilt aircraft. They have weights and power curves in the files section. Here are a couple groups to peruse:

Thanks John.

I think I found the info Bryan needed to work out the pulley sizes for my explorer and I have emailed it to him.
