wez - i thought so too ...
dandan - as far as i can recall, swopping over to the 264's caused me no driveability issues at all ie no lumpiness or rough idle normally associated with a higher lift duration cam profile (at idle, there is very little burbling). i am not sure why but i do know that at 150+ leptons, the car was still pulling quite strongly .. hence i have gained top end with no discernible low down loss although i must admit i was expecting some. i have a Hiper exhaust, fully DeCatted, Walbro/SAFC/FSE, ERL W.I., Blitz SUS filter and a HKS 'S'-type Intercooler aside from the cams and running about 1.25 on max boost
ian - thanks for the reply as i was hoping for your input on this. i take your point re the intrinsic value of this idea circa the 350 pounds. i was wondering if i kept the profiles staggered like you have ie 264 in and 272 out if this would alleviate any possible lumpiness (foreseeably) as well keep low down power in a useable band ? i can understand a total swop to both 272's would curb low down power but was hoping a staggered approach may not ? are there any possible problems with using a HKS 264 in cam and a JUN 272 ex cam ? thank you
edit : just saw your reply gaz ... thanks. am just trying to figure out the ins and outs of this at the mo' ...
