hi guys still building car at the minute and have a R1 5pw engine in and up and running i have a nice exhaust manifold and a power commander and looking at running a pipercross sausage filter engine is low mileage and well looked after what sort of power do you think i will be running once complete and set up?

a rough guess is 140hp at the wheels... but youll never know till you get it dynoed. the powercommander makes a fair difference, you can really feel the difference between maps, but it would help to get it properly mapped cause of the different loading of a bec. its a good engine though and responds very well to being used hard.
