How come highly tuned scoobys still sound throaty then?

Would have thought they would have changed to an equal length systems?

They do, the throaty sound remains more to do with the flat four boxer engine. and the huge pipes they run. The unequal length headers are the bom bom bom noise unique to the scooby.

Where was the zorst from anyhoo.....?

Custom built by a company in St Albans.

looks good, although surprised nobody has comented on the configuration yet

Please elaborate.

That's indeed an "interesting" set-up of cyl 1+3 and 2+4...
I'm no expert in headers pairing, but most 4cyl headers are paired 1+4 & 2+3 to distribute the pulses evenly over the secondary pipes. Yours is like a "big-banger", but you also have big long primaries...
(The OEM cast mani, 1+2 and 3+4 is more about space saving but in the end has the same sequence pairing as yours.)

I did a 1-2 and 3+4 design which would package into a VX and give long pirmarys without modifying the boot and it got slated for being the wrong configuration. The idea with that the sequencial design is that the energy from the first pulse helps to pull the second pulse through. If you look at the designs then generally there is a mix of the 2 and witout testing both I doubt you'd know which is best or if the difference was really that big.

As for 4-1 for SC noramlly in a FI engine all your looking to do is get rig of the gas a easily as posible as you don't need the scavaging effect to pull the gas into the cylinders like a NA as the SC will just push flow in.

Be interesting to see how it performs as I recon similar design (config and runner length) will package into a VX without moding the boot

thats wrong, it would be ( 1-3-4-2 ) red into collector 1 , blue into collector 2 , to merge them in collector 3

Mmmmmm


Possibly wouldn't pass drive by noise test


Noise defenders an absolute must


Correct offset for the VX?

[JohnTurbo]

Europa is a bit menthol! Like!!

[JohnTurbo]

Where are you staying? Camping?

[Mike (Cliffie)]

yup, thats the plan

[JohnTurbo]

Valley hotel for us...decided we needed the full cooked breaky! - Trying to get the mazda sorted after it blew coolant and oil out 2 weeks ago. I hope the VX is more ready!

[luke.]

I got gas cooker. We'll get bacon and beer. Happy days

[JohnTurbo]

Mazda has new water pump...and still it leaks. looking very much like blown coolant seals which is a 3k rebuild, and with only a week to go its not looking good at all. :-( Plan currently is to turn up at a rebuild place tomorrow and beg.
