Noise Test and Engineering Checks

This weekend I took the car back up to see the engineer in Orange. It spent a day in the workshop on the hoist for all the engineering checks, and I now have a list of 7 things I need to fix or change....nothing to onerous.

Todays tests involved rerunning the noise tests I had previously failed. With a revised exhaust, new airbox and some more insulation, the car passed the tests, coming in under the 77db drive by tests and the 90db stationary test.

Getting very close now to a finished engineering report and hopefully a VIN and plates!

Heat shield

After fitting the new air intake, I noticed how quickly the intake piping was getting hot, caused by the proximity of the headers. Given that I don't want preheated air going into the engine, and I have silicon joiners on the air intake, I decided to fit some heat shielding. 

I fabricated up some support brackets to sit between the headers and the intake to hold the shield, then shaped a piece of heat shield to fit it in the gap. Its tight at the front, but has a good air gap for most of the length of the intake and it protects the joiners.

Today has been spent fitting a new quieter exhaust and heat shields....photos to follow. The car is almost ready for its next and hopefully final engineering checks prior to rego!
