Banger Fuel Injection

[JOHNCL]

Electronic fuel injection is complicated. Therefore, case studies are needed to get past the assorted hurdles, physical and psychological. Car magazines have been supplying such stories for quite a few years for hot rod engines. Hopefully, some interested people can supply useful references for us 4-banger fans. Naysayers (aka traditionalists) will tell us their feelings loudly, but I think this thread is long overdue and now quite valid given Terry Burtz's engine foundation and its many adopters. My Burtz engine loves to rev with its modest 6:1 Snyder's head, dual #81 Strombergs, tubular exhaust header, and Honda distributor. As Steve Serr and others can attest from dyno testing, getting air/fuel ratios consistent across cylinders and engine operating conditions is challenging with carbs. Maybe it would be easier with electronic fuel injection.

The new ones are pretty idiot proof. An air/fuel sensor in the exhaust is about all that is needed for the brain to tune itself.



There are hose clamp type connectors for the 02 sensor - so no welding.
The return line does not have to go back to the tank - only to the low side of the fuel pump. We put one together with a T at the inlet to the pump for the return.


I don't see why it wouldn't work as an updraft - there is no float bowl.
