Best mechanical fuel pump for 900 plus sc engine

Has anyone had any luck using a command center where the mech pump lifts it in a basin, and an electric pump shoots it to the carb/Fi? FiTech makes one but seems to be crap in execution. I think edelbrock makes one as well though.Originally Posted by snapmorgan
I have the Baker 15# pump on a 850hp engine with a bypass regulator. It supplies plenty of fuel, but you can see every pulse of the pump in the pressure gauge. I have a mechanical gauge on the fuel log and an electric gauge in the dash, sender is in log as well. Both needles swing wildly and it destroys the little liquid filled mechanical gauges in short order. I even plumbed in a large spin on fuel filter between the regulator and carbs, thinking it might calm it down a bit. Didn't change a thing, but I guess that since liquids don't compress, I should have known better. Does anyone else have this problem?

During the day, you can`t miss em, at night they are blinding, usually have to throw a towel over them.
Since we have headsets the buzzer wouldn`t work.

True and agree so if I am going to both . I see no reason why not. I tend to zero in on oil pressure and AFR's. A little time and wiring is worth the potential meltdown. Might be overkill but so be it. I am not sure where enfines are going to come in at hp wise so just want to be certain. I have to be honest 1,000 hp engines are something I'm not use to running so rather safe than sorry. All else fails it will be fun.Originally Posted by MILD THUNDER
only problem I have with a buzzer, it it better be friggen loud. Could be a bit hard to hear at 90-100mph with twin 900s, blowers, and wind screaming in your eardrums. A bright led light on the dash, will catch your attention.
Why not build a "shut down" circuit that kills the ignition if fuel or oil psi falls below a threshold?
bells and whistles are good indicators, but a human still has to recognize them and then react.
what am I missing here?

I think the dash warning lights will be fine. Likely it won't be an issue anyway but just want to be on the safe side. I can react and back out of the throttles with a warning and go about my day but cutting an engine out at 90 plus is disaster. Been there twice and it's not what I would say is a good time. You can have your hands full in a hurry. Lol...Originally Posted by vintage chromoly

Maybe a circuit that initiates a visual and audio alarm and simultaneously picks a time delay shutdown relay. You could program any delay you wanted, so you could get the alarm and have a chance at throttling back. If the alarm is ignored, the relay times out and saves the engine / engines.

they very well might. These are custom builds so to speak and going into an 12 meter so anything and everything will have to be well thought out and rigged as I see fit. Not my first SC engines but my first with the kind of power we're looking to achieve. I'm just looking to take some precautions cause I know how fast things can happen yet I like simple also.

Tks guys.
