Do you mean...

What are the turbo guys doing when it comes to fuel delivery?

Requirements depend on what you are building. Turbo or N/A., how much boost?... Every other variable...???

typically you chase down bigger injectors. the stock twincam injectors are 190 cc/min. bumping the injectors to replacements between 240 cc/min and 330 cc/min improves headroom.

there have been some recent developments with the chip burners. an aussie (garndi maybe?) can reprogram an eprom in the oem ecu for turbo use and teeth in california can do it, too. :wink:

it used to be that a stand alone engine management system was required. back in the day some of the guys used piggyback controllers. in my opinion megasquirt is the best option for tunable engine management. =)

I think he is referring to people that have a throttle body injection that bolt a turbo up and go. But same thing. Find a bigger injector and know they can only support so much boost as a non turbo computer was not designed for boost but can handel limited amounts.the guys running a tbi 1.0l find a 1.6l injector works well. But it all depends on what you are trying to do.
