Hoping somebody may be able to help I have a 2.0 silvertop zetec in a westfield seiw was running on twin 45 webbers with RL200 cams > I do have a friend with a dyno and we were getting 134bhp @ the wheels we don't get to involved in what the number is !! As long as the numbers are going in the right direction . Anyway I decided I wanted a bit more power so went down the turbo route using a SPA exhaust manifold t3\t4 turbo tubular intake 440 impreza injectors DTA e48 ecu car was mapped yesterday by sitech in rosyth by Simon and very nice guy I must say !!! All went pritty gd not just as much power as I thot but not bad got 172@ the wheels . But im just back from my first track day today and cars terrible seems to take forever to get any pull\boost 5500rpm and just when its starting to get going its time to change gear !!!! im sure there something in my set up that's not right but what ?? I do have a dyno graph but not sure how to post pics but if somebody would like to see it id happily email it to them
