Next I worked on the exhaust area, this area had been concerning me. The IVA test requires that the Db level be less than 98Db at 2/3rds RPM of Peak power, so for my engine that is 4000RPM. So I added a 2nd box to bring the noise down but also have put what is often referred to as a DB killer. And this appears to of worked with it idling at about 45Db and at 4000rpm around 83Db...this was measured on my iphone so doubt its that accurate, but should be under the 98Db...afterwards the DB killer will be removed because not only does it kill noise but also kills power as well. I have managed to hopefully plumb the pipework for the exhaust to where I want it. at the moment its not welded or clamped and I need to make some exhaust brackets.
As well as that I worked on the front bonnet, to get a good fitment when shutting. I used quick catch mini, simply click in and push centre to unclip, they work perfectly! Also I used house door rubbers to keep the bonnet at the right height along the line of it.
Following this I had had a problem id been working on, the IVA states as I've put before all wiring must be securely attached every 300mm. well when the rear clam shell opened up the wire would need to be well over 300mm. So in the end I made some wire mount extending bars, this takes the mounting point to within 2cm of the fibreglass shell when closed but to just under 300 mm when open as shown below. (they are the 3x silver poles)
By securely mounting the cables to the fibreglass and then on the poles it should meet the requirements. Next is to carry on with this work as well as fit the door catch mechanisms so I can open the doors properly.
