I have had my GBS Zero (Ford) dyno tuned by Northampton Motorsport today and they alerted me to a bad vibration in the car which may point to drive train issues - possible gearbox/prop/diff/drive shafts alignment or balance problems.
Apparently, it behaved pretty badly at the top end (clearly, speeds greater than I have taken it on the road thus far since my late Nov. 2020 IVA pass and thanks to Covid, weather etc.)
Has anyone any experience at where I might start my investigation first?
I know my engine is a few mm off centre in the chassis (checked this out with GBS during the build) and I feeI I have been really spot on with everything, believing (perhaps naively), that the prop shaft Universal Joints would deal with minor angle/phasing differences between the gearbox and the diff.
Would appreciate any wisdom please as I am just feeling a little frustrated when my hopes were that I could finally get to drive the flipping thing rather than have to take it all apart again!!!
Thanks in advance.
