how much does your fuel psi effect air fuel ratio on the bottle?
wondering because im running close to 50 psi(no vacume line) to keep my injector pw down. i should just buy some bigger injectors, but im being cheap right now.

is that going to effect it much?

 

Yes it will affect you some. Not much though. You will need a wideband or dyno to get your A/F right though.

Start with the recommended fuel jet and stick it on a wideband. Then go smaller on the jet until your a/f is right.

 

yeah i got a wide band so thats not going to be an issue, just trying to think ahead.


if its a little rich its not going to bother me none, my n/a tune is probably to lean for the bottle anyway.

thats brings me to another question, with perfect bottle pressure and fuel pressure is your air fuel ratio not suppose to change? or are the kits designed to put you a little on the rich side.


thanks for the reply

 

Most wet kits out of the box will put you on the rich side with a stock motor. With other mods and tuning anything could happen. That being said my coldfusion kit when I had stock tune and long tubes was a little on the lean side, but not dangerous.

 

thats good to know, i'll make sure i put a very safe tune in till i get the afr figured out.
