i'm wanting to put a KR zorst cam on the inlet side of my engine...Has any one got any info about doing this mod? i know you have to cut the end off to it will fit but then you have to advance or retart it 6 degrees. how do you do this????? Vduber
You need a hotgolfed pulley like i have on mine.You press off your old pulley,press on new one that has had the timing corrected,fit it in and ENJOY!!pm me if you need 1
u dont get any improved bhp It lowers your powerband insteasd of going mentral at 4k it goes mental at 2k...so it feels like its got alot more power. Vduber
Im havin my car dynod at stealth soon so i can report back.Not only does it give you power at 2k it kicks harder at 5k.It worked well in my corrado but work even better on my friends golf due to its lighter kerb weight and better gear ratios.For wot it costs you cant go wrong
Im sure it would increase bhp as its definatly increased torque.the zorst cam has approximatly 1mm more lift over the standard inlet cam,which is similar to some of the performance cams on the market
Remember the yanks ARENT using the proper machined pulley so it f**ks ther emmisions,tick over etc There cam timing is 5degrees out causing these probs,the modded pulley corrects this and also helps timing it as the dot will be in the factory position
That link above is rubbish!!! If you do it that way and don't time the cam sprocket properly then you are a few degrees out, which will make a big difference in the runing of the engine. You need to re-cut the keyway in the pulley, and beleive me doing this to a hardened pulley is difficult even with the right tools. And while you re-cut it, you can put ti in the right place to re-use the original timing mark.
hotgolf - clearly the man in the know! mind if I ask what sort of driving characteristics you are likely to get from the exhaust as intake? Are we talking mid range torque or top end? Reason why I ask is because I would have always thought that a cam with more lift would shift the power band further up and yet people suggest that mid range is where the gains are made as opposed to the top end. Also, any any power figures/RR prints etc? Reckon you could shift a few!
Can you see why its called a hotgolfed pulley now? The car feels alot livlier at 2and half k so increasing lowdown torque and then it pulls even harder at 5k and feels smooth with it,for wot it costs i would say its the best mod ive ever done and is instantly noticed!
