#1: cams.....for gti Author: charlie-52, Location: telfordPosted: Wed Feb 09, 2011 3:23 pm ---- im thinking about getting cams for my 206 gti 138
basicly i want to know what ones i should go for?
i dont want to high lift as its a daily use car and i dont want to have to go through remap, but i want them to have the lumpy sound to them
also what make should i go for for cost effective but not cheap crap
#2: Re: cams.....for gti Author: MutilateTheDead, Location: DerbyPosted: Wed Feb 09, 2011 3:30 pm ---- I was looking at new camsbut everyone on here said to get a re-map too, and i don;t think they come very cheap
#3: Re: cams.....for gti Author: charlie-52, Location: telfordPosted: Wed Feb 09, 2011 3:37 pm ---- i know a lad who had cams in a saxo vts with out a remap and run fine and really sounded amazing

It's duration you need to be worried about.

Then just fit some Piper Ultimate Road cams to your engine, will need some pockets machining into the pistons. With your standard inlet you'll get all the lumpyness you desire
#5: Re: cams.....for gti Author: Seabook, Posted: Wed Feb 09, 2011 3:39 pm ---- i don't understand at all.
lumpy idle is cause by the long duration of the camshaft and normally long duration camshaft are quite high lifting and need a remap to work well.
#6: Re: cams.....for gti Author: Edward, Location: In the garagePosted: Wed Feb 09, 2011 3:55 pm ---- They also won't give best results on the standard inlet. If you're going to do it, do it properly.

remaps will make the most of your mods its a dumb idea to avoid it
#9: Re: cams.....for gti Author: Edward, Location: In the garagePosted: Thu Feb 10, 2011 1:34 am ---- Also if you want lump cams it means they'll let the engine breath better at higher revs...meaning the rev limit needs to be increased.
#10: Re: cams.....for gti Author: charlie-52, Location: telfordPosted: Thu Feb 10, 2011 2:08 am ---- okay so basically if you have cams fitted it is without a doubt you will need a remap? or will it still run fine without?
#11: Re: cams.....for gti Author: Kersh, Location: Bridgnorth, Nr WolverhamptonPosted: Thu Feb 10, 2011 2:56 am ---- im considering some fast road cams with a stainless manifold and a remap to go with my panel filter and cat back.
from what ive heard thats the best thing to do without going down the route of throttle bodies turbo or full rebuilds

It will run ok, just not to its full potential

it depends on what profile is the cam.
i know cat. has got some newcamshaft for pug engine which require no remap.

but they are just very mid sport cam only
to be honest if they dont require a remap there gunna be s**t, , no point modding and tuning if you dont do it right, there's a big difference from my old mapped gti to my standard gt and it had no other performance mods the standard map on a gti 138 is s**te bumpy torque line

Have a word with Rich [spike_202] - his GTi has cams, done at Pug1off.
Rich is from Telford too

#19: Re: cams.....for gti Author: usher, Location: northallertonPosted: Wed Feb 16, 2011 8:39 am ---- im getting some standard ones re-profiled as i was told by piper anything over the fast road cams they do will require head work
#20: Re: cams.....for gti Author: Edward, Location: In the garagePosted: Wed Feb 16, 2011 9:24 am ---- With the bigger cams you don't need head work, they need the pistons machining. You also lose the camshaft trigger for the cam position sensor which might throw up a fault code on a standard ECU. But that doesn't matter anyway because you'll need throttle bodies and another ECU anything with other cams.

whether you will need to machine the piston is depends on the lifting of the cam.
you might need stiffer valve spring as well in some case.
but how about the lifters then? as i see most hardcore cam require to use solid lifters, why was that?
#22: Re: cams.....for gti Author: Edward, Location: In the garagePosted: Wed Feb 16, 2011 1:17 pm ---- It's the duration that dictates the need to machine pockets into the pistons. The duration tells you how soon the valve opens and how long it stays open. The sooner it opens the closer it gets to the piston - initially the valve moves downwards faster than the piston moves down the bore meaning extra clearance is needed.
Again the longer duration means the opening ramp of the cam opens the valve quicker (in order to reach full lift) meaning a stiffer spring is needed to keep the follower in contact with the cam lobe.
