Semi pp N/A build: question thread

C. Ludwig · 12-01-2011, 03:12 PM

On these NA engines, with the quality and results of the ID injectors, I see no reason to run secondary injectors. Personally, I would run a single 1000cc injector per rotor. This eliminates the tuning headache of secondary injectors. The ID-1000s will idle great, so why not?

The one reason I would consider running secondaries would be to use a standoff injector at the trumpet inlet of a single large runner (ie: full-PP). With the semi-PP, I doubt it would be worth the hassle to setup properly.
