Gearbox mount issues - dr_jekyll - 25-10-2018 Been having a few teething issues now with cracked turbo brackets and bolts shearing off. ![]() ![]() Admittedly the first bracket was an incredibly poor lash up to get the car back on the road. After that i tig'd up all the shit welds filling them right in and then triangulated the arm to add additional strength. ![]() ![]() ![]() ![]() This time tye bracket failed on the piss poor mounting point and poor bolt choice.... 2x stainless m6 bolts that hold the chra in the exhaust housing. ![]() Ive now over engineered the bracket adding a further mounting point, triangulating the whole frame and using high tensiles on every fixing point. ![]() It was suggested to me that this may be failing due to heat expansion and was advised to fit a flexi pre turbo. Now ive never actually heard of this being done or seen it in anyone elses projects so was wondering if this is a feasible remedy. Slightly concerned the flexi may not hold the back pressure and temp as i can peak upto 40psi back pressure on a spike and 800deg c in temp Opinions???

RE: Gearbox mount issues - welshpug - 26-10-2018 use HT fixings not SS, twice as strong. Also is the downpipe bolted to anything but the turbo? |
