Lancia 1600 'carb' turbo, inlet manifold.
Posted: November 25th, 2010, 8:08 pm
Hello Mr Croft.
Hopefully this is a simple question about my Lancia engine that I should have finished soon.
Lancia Delta 1600TC carburettor turbo engine.
Engine cylinder head - standard valve sizes, fully flowed out with 35mm Dia inlet ports and everything done by the book or DVD (but not by me as done before owning the engine).
Was believed to be one of your worked cyclinder heads (spoke to you about this before) but on removing some sharp edges and the lack of your stamp/numbers has told me otherwise at last, but it appears to be done to a very high level.
I have found that the inlet manifold is still totaly standard with smaller rough cast ports at 30mm Dia.
Has the inlet manifold been left standard for a reason? (Negative pressure waves maybe)
The engine has always run like a dream, its power and performace being amazing even on standard boost.
Should I open up, clean out and smooth up the inlet manifold? Or should I leave well alone?
I have Book 1 (well read now) book 2 and your DVD but never found anything about carb turbo inlets, as I'd expect 90% or more turbos are injection anyway if that makes sense. I am still reading your new book but have not been able to find the answer I'm looking for yet (great book, don't know how you do it with all the infomation listed out).
Thank you Oliver.
