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? |

I think you'll find the manifold signature is way to lumpy for a D-Jet to work. All the manifold pressures will be higher because you'll have a throttle plate that is effectively 4 times larger; plus you won't have a plenum chamber or any of the piping.
You *might* be able to get it to run (and by run I mean idle). There are various tricks you can employ to make the D-jet run leaner or richer, like the knob on the top of the brain, messing with the CHT resistance, or changing the fuel pressure. The issue I think you'll run into is that getting it to basically run is totally different from having it run anywhere near correctly. You've got to worry about intake temperature, idling being different from higher rpm running, acceleration enrichment, plus having the basic shape of the map correct. I have some experience trying to get megasquirts to run with unstable map readings (on a cammed 2056), and it's a bit of a nightmare. We didn't have a lot of success with Alpha-N either. Not to say it can't be done, but I wouldn't put it in the easy category. |
