adamj29 133 Report post Posted October 1, 2015 Hey all,Just wondering if anyone could shed any light on a issue I'm currently having. I'm now running my GT86 with the Stage 3 AVO turbo kit, with the new clutch, fuel system etc. Since having these works done, I've started noticing a very slight grinding noise. The noise happens when I'm in gear and when I let off the accelerator, whilst the revs are dropping between 3,000 to 2,000 rpm. It is at it's loudest whilst in gears 2 & 3 and the noise has very slowly been getting louder. Again it only happens when the revs are dropping only between 3,000 and 2,000 and It is more noticeable when the engine is warm after I've been driving for a while. I've tried recording the noise, however with the cabin / road / exhaust noise, and my crap phone, It doesn't pick up on the sound. It is now driving me potty!!! Fensport haven't heard of anything like this before, and have recommended that I bring it in. However as its a good 3.5 hour drive to them I was wondering if anyone on here has experience something similar?Mucho Gracias Share this post Link to post Share on other sites

Mike@TD.co.uk 467 Report post Posted October 1, 2015 What clutch / flywheel is it? Do you have any polybushes installed? 1 adamj29 reacted to this Share this post Link to post Share on other sites

Possibly a combination of those two transmitting some extra transmission noise through the car? Noticed you're not far from us, if you wanted to drop in i'll gladly have a listen for you. 1 adamj29 reacted to this Share this post Link to post Share on other sites
Riceburner 284 Report post Posted October 2, 2015 (edited) It does sound like the noise you get if you have an uprated rear gearbox mount or poly bush insert.likewise if you want to call into U.S. We can have a listen for you Adam Edited October 2, 2015 by Riceburner 1 adamj29 reacted to this Share this post Link to post Share on other sites

smudge 1020 Report post Posted October 2, 2015 My bet is on clutch. My new Xtreme clutch makes a lot more noise than the OEM one did when coming off the throttle Share this post Link to post Share on other sites
adamj29 133 Report post Posted October 2, 2015 My bet is on clutch. My new Xtreme clutch makes a lot more noise than the OEM one did when coming off the throttleIs this something perfectly normal when upgrading the clutch, or can this lead to any issues. As soon as I hear any grinding noises I panic, and start thinking the worst. I would be good if this noise is to be expected. Share this post Link to post Share on other sites
