what are the real advantages of this design?
is the slot parallel or tapered?
Quotewhat are the real advantages of this design?Take a look at the standard TD manifold. You couldn't design worse if you tried.Quoteis the slot parallel or tapered?Parallel - area equal to the intercooler pipe's bore areaI don't know what's up with the images....they were there?
bottom manifold looks to be just a plain ol' SRI single plenum..
I have a 1600NA that I was planning on bunging a Turbo on to create an 'ecoturbodiesel' which I have heard exists(apparently a turbo on whats effectively an NA engine)
QuoteI have a 1600NA that I was planning on bunging a Turbo on to create an 'ecoturbodiesel' which I have heard exists(apparently a turbo on whats effectively an NA engine)Your from the UK and this desire baffles me, the 1.6 ecoturbo as produced by VW was rubbish, as was it's 1.9 counterpart - there was nothing eco about it, you just had to drive it harder and thus use more fuel.I've just fitted a 1.6 eco turbo in a caddy - thankfully I've now found a LDA pump for it Why not go TDI if you want economy?AS for the design of my manifold and the whole taper/no taper issue, I'd rather take a tried and tested design as used on a VW road car, than something designed for motorsport which has completely different requirements to mine. Maybe I could have tapered the designs but I'm constrained by the reality of actually making the thing with hand tools alone and only basic material supplies.As nice as the computer based hypothesising may look, I've had a Golf blocking my garage for 3 years now and would like to drive it !
