The old man has just brought a westfield with a vauxhall redtop in, its fairly standard but with an sbd jenvey throttle body kit and custom exhaust manifold ect, think it wants a good setup as it dosent feel as sharp compared to the 165hp pinto one he had a few years back and surely it should make more than that as there 150 standard? I dont know that much about them so wonderd what power a setup like this should make?
