inlet manifold?

[greg1.4]

just got my new engine in and running..very happy with it apart from....

it has an irmscher inlet manifold with twin webbers, but there is no pipe/fitting on the inletmanifold for the vacuum pipe for the servo?

any idea's on what i could do?

the guy that ran my engine before had it in a rally car, so it had a bias pedal box which means you dont need the vacuum pipe..

unfortunatly u will have to get a bias pedal box or get a new inlet manifold with vacum addapter! u might be able to adapt it but look at some nova sport engfine bays!

[jonn]

u could drill a hole in the manifold then weld a nut on it or thread the hole and screw it in to that

As john said.
Theres probably a flat on the side of runner 4, to drill and tap for a servo union

[andymac]

as above drill and tap the servo thats how i done mine before.

[greg1.4]

can it be anywhere on the manifold? obviosuly on runner 4 somewhere as it is closest to the servo..

[Adam]

Anywhere AFTER the throttle butterfly(as in between throttle and the head)

No4 because its the easiest route to get to the servo from there

[John]

If it's an irmscher manifold, it should have a take off already? has it not just been blanked off.

[greg1.4]

it had the advance/reatard pipe going into the flat on the side of the inlet manifold..

all sorted now though, i put a servo pipe fitting on the manifold and then put a t-piece in on the servo pipe for the advance/retard pipe..
