stevietec Posted May 16, 2005 Share Posted May 16, 2005 For some reason i can only get a top speed of 90 out of my 1.6. As soon as i change into 5th there seems to be a decrease in power. I've had someone say it could be my bottom end thats bust, someone else has said that cause i've got a four 4 2 1 manifold and full system i will loose power because im getting rid of the gasses to easily? Anyone got any suggestions? Would a session on the rolling road be a good idea? Link to comment Share on other sites More sharing options...
Trig Posted May 16, 2005 Share Posted May 16, 2005 did it do more than 90 before? If your full system has too big of a bore there wont be enough back pressure and you lose power Link to comment Share on other sites More sharing options...

Would something like a new cam sort it out? Link to comment Share on other sites More sharing options...

matt1295 Posted May 16, 2005 Share Posted May 16, 2005 mine problem for crappy top end was a full rebuild of a 130 spec zetec exhaust sytem and a decat (if ya got one) but as above a zetec would cure it lolcheers matt Link to comment Share on other sites More sharing options...
Trig Posted May 18, 2005 Share Posted May 18, 2005 A cam would give you more power but the 'in' mod for 2005 is... engine transplant. put the cam in the 2.0 zetec, that would be more fun Link to comment Share on other sites More sharing options...
