Question was, with larger turbos, will the 15psi duty rate of injectors still be allplicable.

 

ie can you run biig turbos at 15 psi safely. or will boost need to be lowered. as turbos flow more air, and therefor 15 psi becomes lean.

 

AMMENDED; for future referance.

Upgraded turbos will flow more air, so you would have to reduce the pressure to correct the afr... not really much point in doing it??

thanks guys.

Best lower it slightly as you'll probably have slightly more flow for same pressure on larger turbos (more efficient so air cooler and more dense).

Why delete your questions?

 

Why not leave the information for other people to search for or use the future... :s

question wasnt directly answered, and cautionary advice given.

readded if that helps you.

No need to be such a prat about it, but if everyone just deleted their questions and discussions wether they get the answer they wanted or not there would be no information on the forum....

no need for the prat comment. i added it back after your comment.

Arguments aside, I have gt525 turbos with stock injectors with a dyno of 365fwhp @ 9psi. According to datascan I was hitting 90% duty cycle. So, if I raised the boost to 14psi without upgrading my injectors I reckon I'd be in trouble. Full spec in rides section if u need a comparison

thanks mate, helps alot. where did you get it dyno'd as your quite near to me.

Was about to say "how did you manage that???" until I noticed the extra 5 on your tubs. :blushing:

Unfortunately, nowhere near us! Was done at Surrey rolling road on one of the south east dyno meets.
