When I do the bottom end of the motor this winter. My plan is to go to 47lb injectors. I was wondering who here has them and how your car runs with them.

Thanks. I do have dual fuel pumps

 

Go straight to 60#. It will give your tuner more room from tuning, along with a dual BAP, you could be good to the low to mid 600s for power.

 

You will also be limited by your blower too.

 

I assume you run a Brenspeed tune - Brent may have to tweak it for the 47's and definitely for 60's.

 

How much boost are you making?

 

Currently make 9.5 lbs of boost. I think the 3.0 pulley is around 13 but not sure. I'd like to go with a smaller pulley so the 47lb injectors would be needed. I was just wondering how your cars have been running with 47s.

 

How is that b326 running? What injectors are you running. And yea I have spoken to Brent about doing Dyno time for the tune. I had heard that the cars can run a bit rough when you get that high. So that ps why I wanted to know

 

The B326 is running great. Pulls like a freight train.
I am still running the 41#'s that came with the E-force. There is a little bit of surging and she can be finicky, but it isn't anything I can't live with. Brent said it would only get worse with 60's. He didn't want to go any bigger because the car is a daily driver 365 days a year, so I am kind of maxed out right now as far as power goes. I wouldn't think 47's would run much different than what I have right now though.

 

You want to have your cake (POWAAA) and eat it too (Awesome driveability)

Injector Dynamics

/thread

 

When I talked to Brent from brenspeed he said that 47s would be tougher to drive for a dd. so I know I can't have both. But if I can go up to 42s and have decent driving vehicle then great. My car isn't a DD

Is injector dynamics a thread

Thanks
