When are injectors needed
Hi all
Currently running a 180 crank pulley with EC heat exchanger + EC tune, looking to do an EC upper pulley too but wondering what the limit is for the current injectors before running lean is?
Is this combo safe on stock injectors?

550CC with a looped rail will give you a safety net.
I would not be so concerned about the fuel injector size (although a concern). I am always scared about high mileage fuel pumps getting clogged up and not being able to deliver fuel.

At least on the 215 there is a fuel pressure sensor and 2 fuel pumps so if one dies it will log a fault put it in limp mode.
At least no leaning out from the a failing fuel pump.
so are we saying 16/17psi on stock injectors without rail modification is ok on stock system? I have a brand new fuel filter also.

Ok so before I look at SC pulley I should look at a set of injectors, are these suitable for the M113K in my car:

Are they a straight fit:

For traditional e55"s just loop the rail, add a center inlet with a 90 degree screw on filter and remove the factory filter. All set. I think the op"s car is set up the same? Learned all this from Chawkins.

I know they're pricey, but the 6 port SLR injectors will make all the difference. Remember, the SLR is rated at 626 hp and tuners have taken it way beyond that without changing the injectors --- and yes, a balanced rail is important FWIW
