max boost on 444cc injectors

[typerrr]

what is the max boost on stock injectors....18-19 psi...just to know ,because it will take a bite of timel before i have my 750cc

Boost depends on your turbos.

Just play it safe. I wouldnt go more than 400hp.

[TrevoR32]

rough rule of thumb is 1hp for every single cc so stockies are good for 444 haha but 400 is better to be safe

You have N1 turbos, but your limitations are your stock injectors. 444cc=444hp. But a general rule of thumb, you don't want to go at 100% duty cycle on your stock injectors, so 85-90% is what is consider a safe good level which in turns get you about 400ish hp. Unless you have adjustable fpr,you can increase the fuel pressure to get more hp to the stock injectors. But, that's a whole other story.

You should take into account they were 444cc new and likely don't flow as much now. Same with the oem fuel pump

Changing the filters in the injector helps let a lot more gas flow through.

set at 16psi for now....pulling good

Prbly close to the limit.
Don't get greedy.
Better yet, get a wideband and egt gauge so you can tell what's going on.
