Re: Any tips separating rusty exhaust pipes?
oolong,
I'd guess you'd agree that the Lomax 2 into 1 isn't a brilliant piece of design, since the diameter of the primary pipes is probably on the large side and the lengths to the join are unequal, the latter being something which has considerable importance for a boxer twin engine...
Btw, if you do check out the internals of a crossbox, you should find that the distance from each inlet to the outlet through the internal baffles is the same.
So, chopping out all of the internals is likely to be counterproductive...
Fwiw, during one of the years when I spannered for the ECAS team at Mondello, the bottom blew out of the crossbox, which wasn't all that surprising as it had done more than a few full race seasons.
Iiirc, there were some hours to go in the race and although the holed crossbox was losing us over a second a lap, Roy and the team worked out that it was better to keep going rather than lose about 10 to 15 minutes replacing the box.
Their maths proved to be correct.
Slightly frivolous question(s) time...
Do you think that any vortex effect would still be evident after the air has passed through a filter element? I'd have thought that the tangential flow is more aimed at distributing the incoming air evenly around the exterior of the element.
Just 'owlong did that engine survive, since 95mph on standard gearing works out at close to 7,500 rpm?
Same applies to the Dyane which was mentioned in another thread, with 100 on the sat nav, or was that kph?

Neil says it all when talking about how hard it is to better the factory original. I would argue that goes for every other part of the car. Take the air filter - it's beautifully designed to swirl the intake air into a vortex.
I once bought a Special which had a pancake filter sitting in the airstream. The car struggled to beat 70mph, even with a Lomax 2-1 exhaust. After not a little experimentation, the car would pull 95mph, through use of a Peugeot air box/filter unit, a ram box and trunking.
As I said above, check out older Alfas to see the exquisite lengths they went to on the inlet tracts, and the exhaust headers.
