Hi Guys

Anybody replace their N54's Injectors with larger ones running on a Jb4?

Planning a build and would love to hear some thoughts\Gains on the subject.

My personal car Is running 300 kw at the wheel and I definately have no issues of the injectors maxing out, there are cars running 100kw more than me and they also don't have injectors maxing out, the weak points is the lpfp not handling the volumes needed and the hpfp battling to maintain fuel pressure at builds over 700hp at wheels...

Ok that sounds good, I'm not planning anything close to 700whp but I am planning a 450whp build and was worried about running the 600cc's hot and leaving no overhead. I know running 100% is bad and thought it might cause issues later down the line.

At 450, you are fine!

Sounds like it..:blab:

Read about a guy in Canada that had issues and sounded like it was caused by starvation. He had 0 compression on C-6 and one of the guys on the forum explained that the issues with the HPFP caused the injector to push air..

This made me worry a bit..
