- Bigger Injectors -

[joeleo87]

hey all done,

im interested in Injectors. im unsure of when they are needed.

i get the idea that they obviously increase fuel flow etc. but do they increase power?

or do they just to keep the fuel pressure up?

if i was to put bigger injectors into my car it would do nothing unless i had a bigger fuel pump? ran more boost?

i have done a search and found nothing like this if there is a thread on injectors alone please redirect me

cheers.

When you are modifying a turbo vehicle, the point of most modifications (eg. upping the boost/bigger turbo) is to be able to push more air into your engine. In doing so, you must also push more fuel in to acheive the correct ratio an engine needs to burn the excess air you are shoving in. This is why you need to upgrade components of your fuel system like injectors & pump.

Therefore injectors alone with the same tune/setup will not help you.

Whether you need injectors or not is all about your power aim - a high power aim will typically need injectors that can push out the amount of fuel you need. A search will come up with plenty of recent threads about injectors and what power each type will handle.

Hi,

When you get a way of adjusting injector opening times (After market ECU or piggy bak) you need to get larger injectors when your current ones are on 100% duty cycle, or "are open for as long as possible"

I once explained it a way to a sibling, Making power is like making a cordial drink. Motors like to use a certain strength of water / cordial (air / fuel) mix. Lean is too much water, rich is too much cordial. ~14:7:1 is the best, but you want it a little stronger under load; 12-12.3:1

So how ever much power your making (cordial mix drink) you want to (relatively) keep the same water / cordial ratios

Injectors simply maintain fuel control to keep within the same strength ratio's through the myamid of differnt engine conditions; they supplement power, not create it. One seperate component doesnt 'make' power, without a dependancy on another. Tis the motors ability as a whole, to move as much cordial mix as possible, that makes poowaah

You might not find info like this on a hipo forum as its kinda 101 automotive

Hope it helps
