All Praise The GTI 3 Posted May 13, 2007 i bought a 1.9 and was told it had a uprated cam but ive never driven a 1.9 before so not sure how quick it should be. how do i tell if it is a performance cam without taking it out??? also i know the later 1.6's have the same head/valve size etc as the 1.9 but do they share the same standard cam? cheers for any help Share this post Link to post Share on other sites
DaveK 0 Posted May 13, 2007 the 1.6's usually have a chamfered edge around both edges of the lobes, although there are afew exceptions i think Share this post Link to post Share on other sites
j_turnell 134 3 Cars Posted May 14, 2007 Only the earlier 1.6 cams had the chamfered edges, most of them are worn out now though, the later 91 onwards looked like the 1.9 cam with no chamfer. If you remove your dizzy, mark the position first to maintain ignition timing, there should be a stamp on the end of the cam. Or just remove the rocker cover and take a pic.

Ahl 4 Posted May 14, 2007 I've always heard that the 8v head flow is nearly maxed out as standard, and that the standard cam is a pretty high duration item. Apparently even some of the 'fast road' cams you can buy are virtually the same as the standard cam. If the engine really does have some crazy cam in it, then it'll most likely idle a lot worse than a standard car, and be lacking in power at low revs. Share this post Link to post Share on other sites
