Talking to a mate today and his mate owns a Vectra 2.5 V6..now its running 170bhp yeah..complete bog standard and he took it to this Rolling Road dude in South Wales (the place sricrew and moi have been to..top place) Anyways..the guy said stick a powerboost valve on and you'll see some interesting results for this 2.5 V6. So he goes out and buys one for like ..what are they £60 abouts yeah? Anyways...he goes back to the Rolling Road guy sticks it on the rollers and gets friggen 188bhp! Just with a power boost valve...that sounds bloody good for under a ton eh?
So i ask myself maybe i'll try a power boost valve even though you hear they only good for 8valve cav engines etc...but whats the hell yeah? Sell it on if it loses power on me redtop?
what yah thnk peeps?
