My Aug build 140 is louder in comfort

Post by ccsb58 » Wed Sep 19, 2018 9:31 am

Now has 50 miles on the clock, only had it a few days..

In park, in comfort (only revving to 4k mind) it burbles and pops. It doesn't seem to do it in sport, anyone with something similar to this? Find it strange.

Quick turnaround there.

My July build with 500 miles on clock has no burbles or pops on revving in any mode yet.

Is it at full operating temp when you carry out this test? If not it could be the extra fuel enrichment aka choke, adding fuel that brings on the pops.

Indeed it is, I wouldn't rev it cold. I tested it after a journey this morning.

I do know there is some pathetic new EU legislation about not having a mode that makes a car louder. The car is generally homologated in the standard operating mode - comfort in the case of these. I wonder if they simply removed the over fuelling strategy in Sport to ensure it complies explicitly?

The cars must pass tests in there respective "Sport" modes, it's possible that now on revving when parked
Comfort makes more noise than Sport.

Very strange. The post PPF b58’s I drive daily are muted in all modes. Do you have a video?

I will get a video shortly

Also, I don't think sport mode makes any difference at all to noise now listening to it closely!

That would make sense, for the reasons I gave earlier.

Sport sounds better when driving but on start up, the default "comfort" setting seems louder than Sport. These cars need a Remus though, it both looks and sounds better

It's nice to know that the exhaust is not too quiet!

Tried mine this evening when tucking it up in garage - on revving it does burble and pop a bit as the revs drop back, much as my previous cars did - I had not yet tried that. No difference between modes.

Still none when on the move yet, half way throgh my run in miles so will see what the extra revs bring.
