Chief Quimby Posted August 6, 2014 Share Posted August 6, 2014 Did you time everything, or just put them on the marks.Running them too, and had almost same problem. Quote Link to post Share on other sites
RobSR Posted August 6, 2014 Share Posted August 6, 2014 Loads of people had problems with them when they were first released. Down to the fact they are just poop and terribly made. Quote Link to post Share on other sites
_shaun_ Posted August 6, 2014 Share Posted August 6, 2014 I run a set from the first batch and they run fine. If a little noisy but il put that down to the shims.Were the first batch not fine and the. He sourced a cheaper manufacturer for the 2nd batch that went horribly wrong Quote Link to post Share on other sites
Ryan-11 Posted August 6, 2014 Share Posted August 6, 2014 Yeah the second batch were awful, the inlet cam was machined wrong, the cam gear locating pin was in the wrong place, replacements were sent out but i never trusted mine in the end. Quote Link to post Share on other sites

srferreras Posted August 7, 2014 Author Share Posted August 7, 2014 I worry about the vacuum that is always in 10Hg to 1200rpm. 1000rpm unless it gets in 5Hg Quote Link to post Share on other sites
Chief Quimby Posted August 7, 2014 Share Posted August 7, 2014 Well, you have to mesure them with micro meter Watch( think it is call), i put mine on 108 degres at 1mm lift.I dyno it at 396hp at 1,85 bar, som i would say they Work just fine. Quote Link to post Share on other sites

Chief Quimby Posted August 8, 2014 Share Posted August 8, 2014 When you buy cams, there is supose to be som specifacation on them. There is not on those speedvision, so i did them, something near 2jzgt, because they have almost same stroke. I am running adjustebel camgear too Quote Link to post Share on other sites
Chief Quimby Posted August 9, 2014 Share Posted August 9, 2014 Could be interesting to know, what orther people with speedvision cams did, and what degree with 1mm lift, or they just installed them, and wondered why they didnt work Quote Link to post Share on other sites
