I would like to know the BHP of my RB5, i've added scooby sport back box & air filter and would like to know how it now compares to a prodrive version.
Is a rolling road test the answer to my question, if so are there any rolling road centers in the colchester area?
How much will it cost, what do ya get for your money?

 

You have 215 bhp standard, backbox and filter will probably give you 10bhp max.

Check the Dyno section to see what others have got.
