my bolt on cover is more for fishing out bits of piston
A question for you, are the main injectors on the engine, or plenum side of the butterfly? I'm thinking about whether you need one or two fuel pressure regulators/fuel systems.
What's the strategy for switching in the second injectors, do they run all the time, at certain boost, certain throttle angle, rpm, or once the main injectors reach a certain duty. Just interested really.
With the EFI, if you're using MAP mapping you want to use pressure between throttle and engine. With MAP and TPS you may want to use the plenum pressure.
For the fuel pressure your reference should be to where ever the injector sprays into (to maintain a constant fuel pressure across the injector).
You'll want your wastegate and boost controller to be from the plenum (well, turbo side of the throttle anyway), that way when you close the throttle the boost at the engine will drop.
If you fit a BOV the ref pipe goes between the throttle and engine.
Your boost gauge is probably more sensible between throttle and engine, but it's not that important either way, it just depends what you want to see. I like to see what the engine is seeing.
Hopefully that makes some sense, it may even spark up some discussion
