My goal is to make the most out of my current setup:
416 LS3
2200R 3.0" upper 8" lower
Methanol
Twin 340lph in tank pumps
The car is putting down 888/784. I currently have 1 78ths LG headers on there now. I'd like opinions on whether I could eek out another 20 whp from switching to 2" headers. I have seen some guys have great results on the NA LS motors and the LT1 motors. Are the results even greater with FI?
I think it would be worth it in your application. I switched from 1 7/8 to 2" and saw decent gains on my 416 NA build. A lot more TQ than i was expecting.
