This manifold looks very similar to the ones Frankthedolphintrainer used to sell. i no cause ive got one sitting in the shed lol

if you can just turn 1,4 bends circled inward a tad it you wont
need extra pipe. Just direct straight pipe to the sides of the
2,3 pipes. Leaving 2,3 squashed up will keep both side separated
without the need of a baffle. 2 YY like will flow very well and
make less welding. Reversion is a terrible waste of flow otherwise
regardless if the valve is closed on the other end or not.
Jmac also suggested in a previous thread to make the flange outlets
not matched ported but 1mm larger so if the pulses reverse they hit
the 1mm smaller exhaust port head face. Jmac can clear this theory up.

I missed that pic Dan, maybe just a couple of short bends trimmed down to merge into that main junction where it feeds the turbo, but a baffle running down the centre of the 2 & 3 runners would serve okay (frankthedolphintrainer's manifolds had this)I thought you had mentioned the baffle a while back.

I suggest runners 1 and 4 came into the collection on top and underneath of 2 & 3, that includes a few more bends though and would affect costs.

Well spotted but I wouldn't be too pedantic about it seeing that the valve will be closed anyway, and the passage to the turbo open good time to mention it though.

Gylezy love your mani but can I suggest a lil improvement?
The 1st and 4th pipes will cause the pulses to be forced
back up each other unless there is a separator or they are
welded onto the 2nd and 3rd pipes only. So youll have just
the 2nd 3rd into exiting into the turbo flange and the others
using part of the 2nd and 3rd endings. Almost like two Y into 1.
Also the angle could be improved by moving the turbo flange out
a little or angling the pipes towards the flange, hope my
image and engrish makes sense.

keen on one possibly two

i definitely will be interested if they fit a 1000

if they fit in a 1k, I know that there will be more than a few keen....

would be good but need a motor too :)
could scrap the ca's ive got and go a series turbo but i dunno :(

thanks,
you know you want one supa
haha
cheers
Dan

hummmmmm looks good
