so wud you all say that it is better do to this exhaust cam mod in stead of buying new from say kent or piper. and what is it that is done to the cam and is it basically running 2 kr exhaust cams in it now?
That would be cool if you could put them on the site.Il ring vince tomorrow! I believe for wot the mod cost (35) its gota be best per bhp mod. Im actually runnin a 6a zorst cam modded but kr is supposably the best.
Martin told me KR and 9A are the same but ABF has more lift,less duaration, unsure on 6A tho The chart someone posted a while ago said they are all the same
i have seen the part numbers of the exhaust cams on here somewhere, if i could find them again i could ring audi to check the cams are the same. I want to do this to my head when the 2.0 litre is in. VW vortex lot have said it gives a bad idle? Is that cos they dont have vince over there this cam mod, can i use a mixture of 6A exhaust and KR exhaust in my head? How much to stealth charge to do the mod? cheers mike
Mart said he compared an abf to kr zorst cam and he reckons abf had 1mm more lift but less duration. The plot thickens
it does indeed. Anyone got any figures for this and is this exhaust mod only useful on the 1.8? GVK can you verify this as you have them in your 2 litre
Gary noticed much better mid range torque from the twin cam mod in his -- but no figures to back it up yet. The performance differance between KR cams and ABF cams is fractional if anything. Me and GVK both had 2.0 16v's mine with ABF cams, his with KR and we both got around 130bhp @ wheels and they where little different on the road.
Swings and roundabouts KR vs ABF cams, ABF more lift but less duration. Twin exhaust cams work ok on mine, smooth power delivery, well as smooth as a valver can be anyway.
Vortex boys are losers. I gathered the info for this mod from there site and realized that if you just fit the cam,the cam to cam timing is out 6degrees which causes bad idle So a chat to hot golf and 35 later,a chainwheel arrived with a new keyway cut in it,correcting the 6 degrees and still allowing the timing dots to line up. I can confirm theres no change in idle and if tub gets my graphs tomorrow,you will be able to see the torque curve! And im running kr zorst cam and 6a zorst cam modded Edited by: flusted
sounds like a better power increase than buying a performance set is it possible to do it your self or best to get it done buy someone thats daone a few and how does the sproket fit on with an en chopped off witch way round does it go once chopped.
I cut my own cam down but you would have to get the chainwheel done proffesionally and pressed on with a hyraulic press. You chop off the cambelt wheel end so its the same length as inlet cam.If you undo the oil cap and have a peek at inlet cam,you can see where vw cut the origanal inlet cam down
all sounds very positive, seems to add more power without any noticable losses. I think ill have to pm hotgolf in the future about this mod. cheers mike
would running 2 of the same cams with the same lift and duration, is it 10.2mm for the exhaust cam, mess up the balance? Most engines seem to run a hotter exhaust cam? why is this? If the KR inlet is only 9.6mm then using a 10.2mm exhaust cam should surely alter things? what are the bad points other than more power?
