fuel injectors wtf is stock size?!
Wednesday, November 15, 2006 12:32 PM
alright so I'm looking at tuning my 440cc injectors, and my injector constant is 0.17800

I've never seen anyone have a constant like that before.

wtf is my stock fuel injector size? I've searched all over and I can't find it

I can't change my constant without first knowing the stock injectors' size

cc would be preferred...

252cc, 24lb/hr

Eco's have a lower number because of a lower displacement.

That's kinda a wacky injector constant... I am almost positive my stock constant for the 252's was like .20xxxx

Injector constant is different for eco's and 2.4's, even though they use the same size injectors. This is because the constant also takes into account the size of the engine along with some other odd variables.
