Thanks Toby, et.al. for the comments.
The actuator when activated only opens the throttle plates a slight amount, I guess enough to provide fuel to counter-act a sudden load. Take it off, and I suspect we have a 38/38 with a manual choke.
So...after a couple of hours of work on a Saturday morning, I guess we will know how well this thing works.
The '76 BMW is relatively stock, with the exception of a Tii exhaust manifold and exhaust system, stock intake with 32 mm ports bored out to 38 mm and ported to match the cylinder head. Emission equipment has be removed entirely. All cylinders have compression within spec, valves properly adjusted, timing perfectly set, etc. Many of the other 2002 drivers in the DFW area here that I run with are using 38/38s on relatively stock cars with very good results (performance and economy). Believe me, I certainly do not want to open the 32/36 versus 3/38 debate - there is already more than enough viewpoints written on the subject (in fact it was those views and comments which motivated me to try this bloody thing).
I will report on my findings!
Best - Tom
