I have what feels like axel tram through the drive line of my bf xr6 atomic build motor. It happens while driving and or stand still with the clutch in. I have checked engine mounts, compression tested, visual check of clutch. Had it retuned but only soften it and brought it closer to 4500 rpm. Any ideas would be great. My gear box wont expect gears as well when hot but I dont think this is link in any way(its got new oil in clutch and gear box). Just get stiff at higher rpm wont going in, have to just wait for a half second for it to drop in. Link to comment Share on other sites More sharing options...

ZAP No boost, no bottle, just my foot on the throttle! Lifetime Members 7,935 Member For: 20y 2m 5d Gender: Male Location: Sydney Posted 13/02/12 11:12 AM Share Posted 13/02/12 11:12 AM Is it a shudder or a engine missfire ? They can feel the same, but you should be able to hear a missfire.A bit more detail is required, or we are just guessing Link to comment Share on other sites More sharing options...

Farkwiz Member 6 Member For: 15y 9m 12d Gender: Male Location: Mackay Posted 15/02/12 12:57 AM Author Share Posted 15/02/12 12:57 AM Its a BF typhoon motor (not that makes much difference) 600rwkw atomic build, all custom intercool and intake (simlar to the Type R) new 84cc VDO injectors, top mount 35/40 high flowed, with a t56 mal wood close ratio box with his twin plate clutch to suit with 3.91 diff ratio, going to run E85 but want to sort this problem before dyno :( its not miss fire. When is was retuned nothing came up on the computer to say there was any det issues. Something feels out of balance... Link to comment Share on other sites More sharing options...
