Pug1off or Lynx bottom pulley - HDIkyle - 16-11-2013
Pug1off works out at £75 posted where as lynx is £89.99 not sure on post for that. Is there a great difference to warrent the prices?
RE: Pug1off or Lynx bottom pulley - cully - 16-11-2013
i think £89 is lynx's old price for the HDI bottom pulley
i have bought two lynx pulleys and both are running fine
my bad should read what section youve posted in
RE: Pug1off or Lynx bottom pulley - HDIkyle - 16-11-2013
Well its for a xud I just put it in xu section by mistake. Is there any differences to warrent the price difference tho?
RE: Pug1off or Lynx bottom pulley - cully - 16-11-2013
lynx one may be anodised

Lynx ones are supposed to be better made although I've never seen a pug1off one up close so can't really comment.
Lynx will also probably do you a better price if you ask. They did for me

BBM make the pug1off pulleys, but you can only buy from pug1off.
Rich W does do a small discount afaik.
Pugracing do them too.

I wouldn't use either. Bye bye oil pump chain if you rev too high....
RE: Pug1off or Lynx bottom pulley - miles - 02-12-2013
Interesting to read that as I have never had issues with mine and that rev's to 8500 rpm currently and the pulley does not come in contact with the pump chain, thats behind the end alloy cover

Why? Cant see how it would effect it tbh!
RE: Pug1off or Lynx bottom pulley - cully - 02-12-2013
dont see how the pully affects the chain other than the early engines with the friction drive sprocket
then only a loose bolt would

Less harmonic damping of the crank.
Miles, interesting. I've found two things by lightening the crank damping too much by use of very light pulleys and light flywheels.
1) snapped oil pump chains by vibration / surging
2) poor rpm pickup on the flywheel due to "jitter" on the crank revolution. I.e. Odd crank acceleration / deceleration characteristics.

Whats happened to yours then jammapic. If so when did it happen?
RE: Pug1off or Lynx bottom pulley - jammapic - 05-12-2013
Chris, it kept happening I suspect it can be made worse with no power steering pump etc.
Put a stock pulley back on and it's sorted...
RE: Pug1off or Lynx bottom pulley - welshpug - 05-12-2013
if its happened to the same engine I would imagine its rather more than just a pulley at fault.
RE: Pug1off or Lynx bottom pulley - darrenjlobb - 05-12-2013
Interesting one, To be fair, the entire point of the pulley stock how it is is to prevent such harmonics / vibrations..but ive NEVER heard of people having real world issues with it on cars...
Its a big problem with tractors, aftermarket pulleys are fitted, and tractors simply snap cranks, have seen it time and time again...so interesting thoughts.
RE: Pug1off or Lynx bottom pulley - Rippthrough - 05-12-2013
It's not as immediate an effect with cars, as they tend to only spend brief periods in the problem frequencies, as the rpms are always changing. Much more readily show with working engines which tend to be running within a few hundred rpm all the time.
Still, the damage it can eventually cause is undeniable. But then most car engines that are being tweaked probably won't be expected to do another 50k miles anyway.
