bodilx6 Posted March 24, 2010 Share Posted March 24, 2010 I heard that the 430 injectors might run hit if they are running close to their max limit (390bph in this case) for longer periods of time. I'm thinking highway blasts on the autobahn or track driving. Is there anyting to this? If so will a fuel regulator be the answer? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted March 24, 2010 Share Posted March 24, 2010 Not sure about running hot, maybe close to max duty cycle. As theyre stuck in a red hot cylinder head dont really think its a problem Quote Link to comment Share on other sites More sharing options...
Wez Posted March 24, 2010 Share Posted March 24, 2010 They are 440cc not 430cc and they are not mounted in the cylinder head, they are mounted in the runners. A well setup BPU motor will be pushing injector duty close to max on the stock 440cc units but its been done for many years on many motors. While an adjustable fuel reg would allow you to up the base pressure this wouldn't be advised unless you have means to control the fuelling, you would need to pull the injectors back otherwise you will just make the motor run richer through the whole rev range Quote Link to comment Share on other sites More sharing options...
bodilx6 Posted March 25, 2010 Author Share Posted March 25, 2010 Ok, good to know. The reasoning behind the thought of them running hot, is that the solenoid being active almost constantly to inject fuel would be in risk of overheating.
