Could anyone running this setup (espcially a Prelude) answer some questions for me? How is the idle (daily driver)? What fuel setup are you using? What's the highest boost you've run and what is the power? I am trying to decide whether or not to install the 720cc injectors and upgrade to an external pump. I am thinking around 20psi should be the limit for a safe daily driven car RUNNING ON HONDATA. Any info would be greatly appreciated.

 

I have 72lb injectors with a high flow intank pump.
Idles fine, but sometimes when I open it up and put it to neutral, or stop at a light the engine dies.
Go for it.

 

You are running on the Walbro 255 high pressure intank I am assuming? One of the things I am wondering is if that intank will be reliable pushing fuel to 720cc injectors over a long period. I don't mean boost duration but just wear and tear on the unit. Things could go bad quickly if it were to ever happen. Thanks for the info.

 

Ive had the same fuel pump for three years now. Still holding up.

 

i use greddy 720cc with hondata and nos external fuel pump with 8AN fuel line for daily drive. i max out at 17psi but it depend on your turbo setup.

Ah that's good to hear. I want to run 20psi just for track runs. The 550cc and the Walbro seem fine right now and I was just wondering how it would handle 720cc.
