by removing the "bottleneck" it should have a performance increase...the way i see it, it should stop exhaust gases backing up and stalling the turbo just imho though i have never tested it, but anything that allows the engine to breathe better has to be worthwhile, normally the case with N/A stuff, but i am new to turbo`s

What difference will this mod make? as were only talking of a few mm?







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 Now everyone's doing it!




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

Would any one be interested in a CAD created elbow to fit your own personal "size" exhaust

In STAINLESS STEEL - cost unknown but if enough people interested etc.....

Cheers

Thanks

Yes I see what you mean, however I am talking of casting the elbow and for that matter the exhaust manifold as well, I guess the downpipe could be welded onto it after all the ops are done.

would you not end up with stress fractures down the exhaust pipe, with it being solid...vibrations etc etc.

MRA it would be nice to do away with the flange on the T3 elbow where the down pipe couples to.

this is a source of pain for most of us "blowing"!

as it does not make a 100% gas tight seal,

if it does, its not long before your back to it again waving the spanners at it has always been an ongoing issue and needs to be put to bed once and for all

i trust you would make a prototype & i bet that you would sell many!*wink*
