I had an engine build a while back and replaced the cams as part of this, when it went back together we could not get the power back to what it was
(280bhp down to 220bhp ish).To address this we added a boost controller
(taking pressures to 1.2 bar) and HKS Fcon V pro installed and mapped by Abbey Motorsport (so no slackers). They upped it to 245 but could'ent see why it was'nt getting more. Eventually engine failed due to oil issues...almost beside the point.I called up Turbo Technics for some advice, as part of this I went through some of the cars issues and was told that the Turbo was fine and then they said that the turbo didnt play well with aftermarket cams
(piper fast road) so I should go back to standard to get the power back!Am I the only one who has ever had this issue or has anyone else found that cams can reduce rather than improve power?
Grrrr @ PiperNB: I have vernier pulleys and they have been set up twice now to TDC
(as it was considered the problem a few times during fiddling works).
