I talked to a tuner today and he told me that if I was going to be running anything over 250 hp my 440's would not keep up??? This just doesn't sound right Thoughts?

 

I've maxed them out between 305-317whp. I typically cut them out at 300whp as you don't want to run the injector past 80% duty cycle. Fuel pressure obviously plays a part in this as well... but rule of thumb is 300whp.

 

Pulled this from Phearable.net:
440cc = 280-330whp

Thanks guys....

 

I've pushed them to 365whp before, but i highly recommend you dont do this . The guy I was tuning just told me to keep cranking the fuel pressure up and that he didn't care that the injectors were maxing out
