Φιλε Ayrton αυτες ειναι οδηγιες κατασκευης χταποδιου για το αδερφακι του τον 16βαλβιδο 4A-GE ειτε σε 4-2-1 η σε 4-1 και διαστασεις του χταποδιου που βγαζει η ιδια η TRD με τη μονη διαφορα οτι αφορουν την πισωκινητη εκδοση του μοτερ.
Ελπιζω να σε βοηθησα.
The standard RWD system has 28" long secondaries between the manifold outlet and the tail pipe junction. The TRD RWD exhaust system utilises the original cast manifold and then breaks into two 42 mm diameter secondaries that are 485mm long to the junction, followed by a 330 mm long 50mm diameter pipe to the muffler, a 640 mm long section containing the muffler and finally a 520 mm long megaphone expanding out to 57 mm diameter.
Local tubular headers I have seen are 4 into 1 design and have either 1½ " or 1 5/8" diameter primaries and a 2" tailpipe. The headers are not very precise - the RWD primary lengths range from 21-28", and FWD from 12-14". I have been told that 2.5" exhaust systems on 4AGEs are very and that 2.25" is a better diameter to go with.
Best I can figure (from a graph I got sent) the
l is about 28" primaries on 4 into 1 headers for a 4AGE. The set I was building for the stillborn 4AGZE powered Ford 105E Anglia (1964 ) were 4 into 2 into 1 with 14 inch long 1 3/8" primaries, 28 " long 1 7/8" secondaries, and 2 1/4" tailpipe. This was based on the best I could figure it out and what I could get to fit. I was building them from pre-formed mandrel bends, which were to be welded together, hence I would have had a very accurate means of establishing the lengths. The primaries and secondaries would have been within a couple of mm in length to each other.
