I really appreciate the information you've shared in this videos and im excited for your next video. I haven't found anyone who has explained this anywhere near as well, nor anyone who's shared the information about their tools and parts.

Thanks for the video,very interesting and you simplified the system a great deal.Looking forward to next video.

Just found these yesterday and caught up. Been helpful because im an idiot who wants to run it on the street. My only advantage i have is im aware of my stupidity. Keep them coming this is the most informed/indepth in the years ive been looking at constant flow

@zragevii4705 Год назад

I'm trying to do the same..🤣 big v8, small car, mechanical injection and manual trans. What could go wrong..🤣

Sorry I missed the beginning. Very informative.

Excellent info on mech injection...looking forward to air/fuel mix management.

Hello, thanks for the videos and information. Very informative. I do have a question about your setup. I know you have -12 lines from your rear tank, but wondering if the electric pump could become a restriction wide open... the surge tank will cover it up while it has fuel in it of course but if that gets consumed... 100gph would be less than half what the waterman pumps. I understand quite a bit returns via the main pill. If the surge tank held enough fuel for a whole pass it wouldn't matter but it doesn't look that big... Thanks again for all your time and explanations.

I may have mis spoke. My electric pump is advertised as 450 gph. I think that is rather overrated though. Thanks for the comment. Keep me honest! Cheers!

Shit gets deep when you get into the high speed line details, on top of all the other plumbing, haha. Its crazy that you actually made it make sense in the easiest way possible.

Well done !!!

Great info! Where did you get the surge tank? does the float switch kill the pump when it is full? Can the cell just stay open during operation or do you need to open/close the noid?

@digitaloverdrivesystems Год назад

Hello and thanks for the note. I can let the pump run continuously but have a switch to have it turn off when the float sw activates (full). It saves the battery when full flow is not needed. It is an aircraft fuel switch I found as surplus. The surge tank is an old CO2 tank for a paintball marker gun. I modified it and had it powder coated inside and out. Kinsler sells similar tanks but they are a few hundred dollars as I recall. The tank vent solenoid opens when the electric pump turns on, so it is always sealed when the pump is off. I hope that helps answer. Cheers!

@@digitaloverdrivesystems Anything in place for when on 2 step/trans brake or just mat it and go? I just got a old crower bbc unit and it's my first attempt at stack inj.

Very good, your high speed is cool,I have to use springs and shims to reach my desired pressure,I need to find one of those cans.Thoughts on high speed and a scoop? That’s where we are at,more air more fuel? This year I’m going back to Bonneville with the high speed and starting with a super rich pill.Also,I just had to replumb the entire car,lots of changes,and I ended up using a fuel log mounted away from pump which makes access to the pills super easy,wish I could attach pics Thanks

@digitaloverdrivesystems Год назад

Hey Steve, thanks for the note. Happy Easter! So the challenge would be to measure or somehow calculate the increased volumetric efficiency of the engine with a scoop at the target speed range and determine an appropriate amount of fuel that can be added. Do you use any sort of O2 meter or wideband that could help determine the proper air/fuel ratio? A data-logger?

Id like to see the picks - you can email me at speedy@digitaloverdrivesystems.com

Look for a WAT766220 Waterman Adjustable High Speed. Not made anymore, but I just saw one on eBay....
