Redline Pulse Duration

[decco]

I'm just doing some math for some EFI calculations and I was wondering if anyone has measured the stock SR redline injector pulse duration?

injector pulse width at redline @ 11 psi with only intake and 3" exhaust is 65ms-71ms depending on ambient conditions

Maybe I'm confused or maybe I'm not reading your measurement right but what you have, 65-71ms, seems to be extremely high. Maybe you can correct me on this but from what I've read the stock S13 SR has a redline of 7,500rpm so that meens that it is 8ms per revolution, so it should be 8ms or less for the injector pulse duration at redline.

yeah mine are set at like 8.78ms under boost at redline
