crossflow exhaust manifold
Any ideas on what size tube I need to make a 4 branch manifold?. The exhaust ports are about 28mm dia and i was thinking of using 32mm od x 1.5 wall
tube. What sort of length do the primarys need to be?.I will sand bend the tubes and converge into a 2inch collector.
Paul.

Will be picking up a lol***st manifold next week.
will let you know what length the primarys are. (It's a four into one system)

The stainless steel exhaust manifold lolo sells for £90 sounds a cracking deal.
BEWARE though because steveM has a book version chassis,measured up and it wont fit.
They may have altered since then,best to measure up first.
Pipe ends up at pedal box or somewhere round there.

the pipe conflicting with the pedal box is a problem for the pinto runners, if my X-flow exhaust hits the pedal box i think i may have messed up.

Thanks that will be a great help,i am going to make one for the fun of it and to gain experience before making one for a bike engine.

i remember reading somewhere that as long as its not smaller than 80% of the valve diameter for race and 75% for road.
the smaller 1 gives more bac pressure which improves low end torque but less revs. i think??????????

Dan,it was a x/flow.
the pinto i know about as i looked into it myself,shame as its a good price.
The only way i could get it in was to move the eng forward 20",but if i did that i may as well bung a prop on the front and add wings'n'tail

But it wouldn't have been as fast as a locost.

keep us posted about this manifold mate!
I was looking at the same one - it sure is shiny in all the pictures!
Been put off by bad reports on this site, and I'd be interested to know if they've fixed the problems.
Still nowhere near needing it, but it'd look nice in the garage...

No worries then,they must have changed the manifold in the last 18 months.
It was rory of the lolo shop that told me it wouldnt fit,will see him at donington anyway to ask.
