Which throttle blade do you drill a hole in? Also,,,concerning the throttle blade,,,which one is the secondary and which one is the primary.

I have the brass plug completely removed. I have not been by the engine when its runnning to see what the IAC is doing.

Keep the information coming., I can see I have a task ahead of me to get this engine right.

Thanks guys,

Re: Whipple SC blower surge on 502 mpi

It would be nice to see some pics of different installations.

ANother question? How or when does the whipple computer tell the extra injectors to pulse or fire fuel to the blower. I know there is a vacuum line that ties these two computers together, but is there anything electrical??

Thanks
