Since it is manifold pressure based and manually adjustable, with some tweaks it should work ..... right??
My 914 is a 1973 1.7 ...... so I was thinking of going with 1911cc kit and tweaking the D-jet. So just a question to see if anyone had tried D-jet Individual Throttle Bodies or if anyone thinks it would work? (IMG:style_emoticons/default/smile.gif) Is 100 HP possible from a 1911cc with ported exhaust ports, stock D-jet and stock cam? |

You can probably convince it to run, but it'll never run right. The massive vacuum fluctuations as the valves open and close will confuse the heck out of the system. You can even those out if you tap into all four manifolds and combine the signals, preferably with enough volume to damp the pressure waves. Which gets you back to having a common-plenum system, if the "taps" and the "combiner" are large enough.
I recall that some MS people have gone with a "combined" setup that uses throttle position from idle to half-throttle or so, and MAP above that. It sounded like it worked OK, a little bit better than a pure alpha-N system, but wasn't worth the bother. And that's on a completely-programmable system. --DD |
