Hi
We installed the Moss MP62 with power and timing cards and dual throttle bodies yesterday and today. Actually son Max (MJO) installed everything and I just passed him the tools.
But we couldn't start the engine because we'd overlooked getting a second throttle cable......oops!
Hoping to get a cable from Moss Bradford tomorrow morning.
In the meantime yet more questions we'd appreciate help with please.
- because we are using, courtesy of one of Phil's (PJB) kits, dual throttle bodies we didn't have to relocate the idle control valve onto the firewall as is required in the Moss assembly insructions. In the Moss rotomoulding which joins the air filter/MAF to the 'second' throttle body there are two threaded inserts. There is also one threaded insert in the adaptor plate between the 'second' throttle body and the supercharger. We have assumed that one of the inserts in the rotomoulding should be connected to the idle control valve on the firewall.....if it were there......and thence to the insert in the adaptor plate to control tickover. Because we haven't got an idle control valve on the firewall we have simply blanked off one of the threaded inserts in the rotomoulding and the threaded insert in the adaptor plate. Is this correct?
- because we have no idea what the second threaded insert in the rotomoulding is needed for we have blanked that off also! Is this OK?
- in Phil's guidance on how to use his dual throttle kit he mentions that a vacuum line is needed to the supercharger actuator. We presume this is to operate the supercharger bye-pass valve. When following the Moss instructions we have not seen anything about taking a vacuum line to the supercharger. Have we missed something important?
Many thanks for any help.
Stephen

Did you not get a long throttle cable with the moss kit if you did you cut this one down for the second throttle the stock one stays where it is.
dont suppose you have a link to the moss instructions?

edit

just seen the moss instructions yeah looks like your right blanking those 2 connectors off

just bring a vac feed from the inlet manifold to the actuator on the charger and your good to go

I expect the standard moss kit takes the vacuum feed for the actuator from just before the blower.

Yes, that's why we didn't have a second throttle cable....we expected there to be one in the Moss kit, and we neglected to check this out before starting the installation.
Could it be that one of the threaded inserts in the rotomoulding should be connected to the breather out of the cam cover which was connected into the original cross-over tube?

That's a really useful observation thanks. Have read the instructions for the fourteenth time and cannot find any mention of connecting a vacuum line to the charger. However I notice on one of the photographs that there's a line coming off the adaptor plate between the charger and the 'second' throttle body, so this might be the take off you mention. If it is, the supercharger has been supplied with the vacuum line to the actuator prefitted. Will have a look at the charger in the morning and see if this line goes from the adaptor plate to somewhere on the charger. Many thanks for that
