Don't take it out to a 50mm diameter or you'll have machined into thin air!

47mm ID id a good medium.

I must admit, I think I could have opened it up more without getting into trouble though...

Ben, I wasn't happy leaving a 1.0/1.5mm mm wall thickness - so erre'd on the side of reliability / safety / caution. It is a casting afterall, and thin structural castings are asking for trouble...

The elbow (or mine was at least) necked down above the lip that the clamp sits around.
I actually had mine milled out so know it's a perfectly round 47mm - approx 35mm deep from the end. The step (from the end of the cutter) was then blended into the elbow with a stone.

Just measured one up in the garage, the very outside is 50mm, a few mm down up the elbow it is 48mm with plenty of meat left.

TBH i could'nt exacty remember the diameter, 52 rang a bell.

Basically we are opening the elbow out to as close as possible to a 2” system = 52mm
In essence this reduces the effort for the turbine (it spins up more easily)

As it has less of a restriction
& now is suited to as best we can get to a 2” system!

hope this makes sence

I think..... (will check tonight) an elbow from a Saab 900 fits and is a fair bit bigger bore than a metro one.

Area of stock eblow is (guess) 42mm ID
Area = (PiD^2)/4 = 1385mm^2

Open it out to 47mm...
Area = (PiD^2)/4 = 1735mm^2

1735/1385=1.253

ie a change of 5mm on diameter = a 25% increase in flow potential...

My elbow was modified over winter 2002/2003, kept it to myself though*wink* Now everyone's doing it!




ps - sorry for your post looking like i've edited it Nigel - i pressed edit instead of quote!!!

Same here Dave, did the mod and kept stum. I originaly thought of it after reading about Subaru tuning years ago where huge downpipes were the key to easy power.

But i am sure there a few more mods under the hat.
