Straight 6 noise: TVR versus Porsche
Discussion
Apologies for my ignorance, but I wondered if someone could summarise for me why the engine noise for my TVR (Speed Six) is so different from that of a Porsche which also has 6 cylinders in a straight-six configuration.
I get compliments quite a lot about the noise, and it is indeed alive, burbling and wonderful, but when I try and explain why it differs from that of a Porsche, I'm a bit stumped.
Cheers to anyone who can supply some choice words that I may use to explain why my pride and joy is so aurally pleasing.
Oh yes, and my Cerb has stainless steel pipes.

The naked engine is just a steel kit of bits and pieces. That's the basic sound. The variables are the hundreds of components, the way they work together and the adjustment off it all. Just tinkering with ignition or intake can make a huge difference soundwise . . . 70s racer Porkers sound luverly BTW.
A straight 6 TVR can be compared to a Beemers 6 - but then I would be rude ;( A Porkers 6 has always been a flat 6: 3 cilinders on each side of the crankshaft . . . Compare that with an old Beetles flat 4, Corvair flat 6 or Scoobies flat 4 turbo.

A-ha, that's what I was getting confused about. I was always of the impression that a Porker's configuration was straight (in-line) six, rather than the 'flat 6' that you've explained, 'flat' meaning opposed?
I'm sure that if I ever got round to fiddling with my 964 while I had it, I'd have found this out.
Thanks for everyone's input so far.
My exhausts also make a bigh difference to the overall noise, which I'm pretty happy about.

Question: What (if any) is the difference between a boxer engine and a 'flat' 4, 6, 12?
I thought it has to do something with the crankshaft?
Who can shed some light on that matter?

Most MGBs all sound different They've been worked on for over 30 years!
Well, not really... Not much development done during all those years of production.
Except for some castrating to comply with US regulations.
A lot of the differences in sound can be explained by the different (aftermarket) exhausts and airfilters.
A stainless steel exhaust sounds different than a mild steel exhaust.
And then you got big bore exhausts, sport exhausts etcetera...
Also a healthy engine sounds better, more powerful, than a worn engine.

And perhaps as its mounted at the opposite end of the car, so the exhausts are much shorter...
