- VZ Acclaim Alloytec V6
Hi all, just had a random thought, and wanted to see if anyone has tried/seen this done, as after a short search on google, I couldn't find anything and had no idea how to find something on it.
Anyway the idea is to do with how (as I understand) V8's that run using a crossplane crankshaft result in having two pistons firing one after the other in the same exhaust bank/pipe/header/extractor, which provides what sounds like a higher pressure pulse from one of the pipes (assuming a twin exhaust system right through), to give that typical V8 rumble.
On top of this, I keep hearing that V6's such as the alloytec don't sound awfully great with an aftermarket exhaust?
So! What if there was a pair of headers that ran like the stock ones, other than 1 piston on each side crossing over to the other pipe so that two pistons fire one after the other in the same pipe for a twin exhaust?
Eg. if the piston order is:
2 1
4 3
6 5
and the firing order is 1, 2, 3, 4, 5, 6...
can we run pistons (2, 4, 5) in one header
then have pistons (1, 3, 6) in the other header
so that 4 fires after 5 in the same bank
and 1 fires after 6 in the same bank?
(though this could work by switching any pair over, but I figured this would be easier to make an EL header for this setup)
I wouldn't imagine this would provide any performance benefits, but maybe it would sound alright and be easier than changing the firing order or crankshaft?
Just wondering...
Cheers!
