Bit muffled but it was my mates sh*tty old phone, and that was with the Quiet XForce system... 1 Link to comment Share on other sites More sharing options...

Boosted1 Member 346 Member For: 16y 26d Posted 06/04/13 05:58 AM Share Posted 06/04/13 05:58 AM well Atomic may be new shafts, but crow are def regrinds! we have had alot of problems with shimming cams as the lifter recess in the head are all different depths. meaning they all require all different sized shims.the stage 4+ cams are huge compared to fg cams. I dont think you can use vct on them! stage 4 is the max you can go with using the vct.here ya go jet, bit of reading for ya http://www.atomicperformanceproducts.com/camshafts.html Link to comment Share on other sites More sharing options...

Gold Donating Members 23,708 Member For: 16y 6m 19d Gender: Male Location: Adelaide Posted 06/04/13 07:55 AM Share Posted 06/04/13 07:55 AM (edited) Correct stage 4 is the max on VCT but small additional overlap is gained off 4plus and 5 cams In all honesty keep the 4's with VCT and have your cake and eat it 2 Wonder if the head can even take that much lift that the 4+ and 5 advertise 13mm is huge !!
