whys no one use aftermarket cams on a 1.8t?

[davemk4]

even though i have no interest in messing with my cams. ive yet to see a member with aftermarket cams? how come as for sake of fitting them you get good gains? wouldnt this be good to do for stage 2?

Pair of cams £450? BHP gain 20? (if your lucky)
Remap £450? Gain 50bhp?

ye but if you were wanting as much power as possible without maybe changing turbo and the extras needed. this would mean a big power stage 2 remap at a guess?

They can be a bit of a false economy with modern forced induction engines.

NA 1.8 20V cams giv good gains don't they?

[gazareth]

you can get massive power gains on turbo engines before you have to consider a cam swap.

From what I have gathered the isn't much to be gained from cam swaps on 1.8t's.
Prawn did the 1.8n/a cam swap on his and the gains were debatable as he gained a tiny amount in one part of the rev range but lost it in another.

I'm still waiting to be convinced its worth the effort!

[davemk4]

They quote 15bhp + on cam websites iirc.

[golfyste]

Any actual evidence though using back to back dyno runs?

I've also seen manifolds and exhausts that quote "upto +20bhp" etc

[mrsaunders]

Aren't the turbos limited to around 230-250 max, so where would you fit this extra (debatable 20bhp)
