they're just 43# delphi injectors......pretty sure they're the same one's in the 8.1L.
why bigger injectors? you planning for FI
Simple: 408 on steroids!
single digits coming soon!
43's are on the newer motors with Flex Fuel...a lot of people run 500rwhp with them then step up to 60's from there and those will carry you to about 900rwhp then from there 75 or 96's
2006 silverado SS....Clifford Jr...turbo coming soon
1970 Chevelle ly6 swap....d1 coming soon
Just wanted to know about how much power I can make at the wheels with the injectors I have now. I would like to get into at least the high 12 1/4 mile with the 43# injectors.
I'm running 42's at 81% DC spraying 50/50 meth and making 422/411. Still have a little more to go...
