Velocity stacks...

[inlineS54B32]

I am pretty sure that this was covered a bit a while back, but it looks like they are progressing a bit, and from what the captions say - are actually tuning these things to make power... Curious about these - they are extremely sonorous; really brings out a great noise from the S65 :-)



Almost too much noise - but with the hood closed, I am sure it wouldn't be too bad... Still don't like the fact that the engine would be breathing in dust.

Cheers.

The work @FluidMotorUnion did with these was great but have yet to see any real power gains demonstrated.

@Sticky, you know what - I was falling asleep when I posted that last night... I now realize that the video is from 2010, not 2011... I thought it was a new video... You can remove this thread if you wish - it doesn't contribute much.

Cheers.

Well what were the results of the test?
I can tell what in theory should happen due to differences in stack length. But I would really like to see real world data.

No big deal.
