The brake balance issue has been fixed by changing the setting on the remote adjuster. The noise issue has been somewhat perplexing. Marc borrowed Damian's noise level meter and in the workshop the reading at 7000rpm was 95db from the exhaust, however the reading at the IVA test was 104db with a calibrated meter. Marc has added an extra baffle to the exhaust in an attempt to make things quieter.
To try and help out, I bought a noise level meter from Maplin and sent it up to MNR to get another reading. As a precaution Marc agreed to order some sound proofing to fit to the engine bay and also to connect a flexi hose to the air intake of the stock airbox. The idea of connecting a hose to the air box came from a friend of mine with a Caterham, apparently Caterham route the inlet of their airbox on the R500 away from the induction area. The ducting moves the induction noise away from the engine and to the location of the outlet.
As the noise level reads an acceptable level and is under 99db the car is being booked in for a re test. Hopefully I will get a better result.
Good luck mate. Been a pleasure reading your blog so far. Coming in very helpful.
