Who’s up watching these late night uploads?? 🙌🏁
I am! @jellybeansupra
Watching from Portland, Or
Almost 9pm here
Almost midnight! Let’s go! Major help planning builds! Wealth of knowledge!

I love it when he said "a very humbling experience" 😅 I've been looking at the injector duty on mechanical car and it's noticeably lower than the electric with same size injectors
Adds minor plumbing but, some add a small electric pump to prime a mechanical fuel system.
With proper fuel system design and changes to start up tune, excessive cranking is at a minimum, even after sitting for days.
Great video like usual and one I needed to hear. I have reached the limits of my electric Weldon pump and need to upgraded.
We know you needed it 🏎💨 🤝
Listen to Uncle Jay my amigo. 😉👍
And if you don't need that Weldon anymore, I'll take it off your hands. 😛😁
Having a practical examination tommorow quite helpful
You just solved my answers! few months back I saw a supra in the drag pit and always wonder what was that mechanical thing in front of the cam gears do! I guess only fast guys know what it does lol
Great information thanks for sharing
Always like the information that Jay passes on to all of us.
Thanks Jay.
Thanks Tim!
@@realstreetperformance You're welcome. Keep them coming. They're a great source of information 👍
Really enjoy listening to Jay. Always learn something new. Thank you
Coffee and Realstreet in the morning. Winning combo!
Always making learning fun!
Thanks for breaking that down so well. Love the content.
Glad you liked it!
Absolutely correct.
I like this content J, Thank you.
thanks again Jay
I have heard and read negatives about using a hex drive mechanical fuel pump mounted to the camshafts. Maybe it is only on small numbers but there are reports of the hex drive breaking. Would a cable driven or belt driven be a better option in terms of reliability?
I run a mech pump on my street car and it doesn’t miss a beat
Running mechanical on my k20
Starting is fun
Thank you
Do Weldon make an electric high power pump that can be used continuously?
My MagnaFlow can keep up. Can you please reply with the Weldon part number if so
Which Magnafuel? What HP level?
1st! Awesome content Jay!
Whats a good fuel pump and injectors for 800hp ratings ? Going to be running a single pump and 4 injectors
Have you run a mechanical on a drag and drive car ? How did you set it up?
There wont be problems with putting mec´pump on a 4 cyl? with vibrations and such
Weldon ftw!
Hi Jay, does a mechanical pump heat up the fuel much if it’s not being used to capacity? A street car for example that runs flex fuel, running a tank of gasoline would be using only a small percentage of the output of a mechanical pump.
No more than an electric, in fact maybe heat it less from not having a motor heating up the housing.
But most importantly is to have the proper sized regulator to return all the unused volume of fuel. The resistance to bypassing is what generates excessive heat.
Patiently waiting for your Black Friday sales this year Uncle Jay with a wad of money. 😁 Also, tell BC to get off their butts and make some cams, the backorders there are killing me and making me want to swap to HKS simply due to availability. 🤔
Might as well, HKS is just as good same with Tomei
try kelford
I was debating on going mechanical or electric..I decided to go with a radium multi pump surge tank setup. Came down to price
Surge Tanks are great options!
Hi,Jay thanks can you help me to recondition my mechanicle pump plse Edward
Isn’t one of the biggest advantages of a mechanical pump is constant flow regardless of pressure?
What about BF sales?
So those my stock Honda need a mechanical fuel pump
A few things that should be noted here.
That weldon pump is roughly 7 GPM which is not that big in the scope of electric pumps, Aeromotive has a 10 GPM pump and will soon release 12 and 15 GPM pumps.
The surge tank in your original setup negated any of the safety and crash benefits of keeping the original tank.
Crank to run is an issue in the tune, not with the fuel pump, I have owned and tuned multiple cars with mechanical pumps that will light off immediately.
A problem with the track with a relay can be frustrating, but you can get relays at most auto parts stores, however, if you lose a belt your weekend is over unless someone at the track has one. A PDM fixes both issues.
Those high gpm aeromotives are brushless, Jay mentioned that option in the video. That Weldon is probably one of the biggest non-brushless pumps available
@@Carbibbles Listening is hard when you come from a certain part of the world
There are solutions to everything he mentioned, nothing new. Comes down to how much money, how much weight and how many potential points of failure you're willing to throw at your setup.
Good night Teacher Jay.
Good night! Thanks for watching🙏
@@realstreetperformance all the time...knowledge is power..Keeping TEACHING
💯
Don't assume "Jay" is the one responding to these comments ....
@@ACommenterOnRUclips and that's fine with me, I Respect the teaching lesson.
A cable? Does he mean hose?
What about using an exhaust fuel pump? Like a turbo, thinking of rocket engine fuel pumps
Has anyone ever used one in a car?
Power is thru the roof but with all that fuel pumping mpg must be 💩 but hey it’s a trade off that you have to accept
Has anyone ever tried to run a mechanical pump with a small electric motor?
Yes, that'd be a Magnafuel 4703
How come there is no mention of parasitic lost with mechanical fuel pumps? Hydrodynamic friction lost is huge if you are looking to extract every horsepower that a motor can produce. Just like getting rid of power steering and mechanical water pumps. The is a definite gains. Mechanical fuel pump is no different.
It's not significant enough a loss to sacrifice reliability or an engine or a race.
Winning the electrical and reliability battle is worth a few horses on a 1000hp+ forced induction set up. If you’re running an NA K series at 300hp, mechanical probably isn’t for you. In my 2JZ I’d rather not even add a second electrical pump, I’d rather go straight for the cam driven mechanical using the OEM electrical pump as a primer, I’m okay with spending 20hp to not have to electronically stage a second pump, adding another relay, surge tank, and spending 15 amps on the second pump.
@@BEANS-O-MATICtransmissions as much as water pump and power steering I'm sure but if you are looking for the edge, with never technologies like brushless and variable pumps that can support more than 3000hp /2500hp ethanol, yeterday's unreliability is in the past.
Okay so my question is what about everyday driver mechanical fuel pumps?? Did they last longer than the modern ones? That's my real question because if they do, if you're building a daily driver you better go mechanical because if you're somebody that wants to drive a long time and not be having to fix everything, basic is better. I'm sorry. Yes, roll up windows fall off the track sometimes but it's a lot less often than window regulators failing and a lot easier to fix and cheaper..... I'm sorry but sometimes basic is better. You know that's the problem with automotive industry. They lost sight of the automobiles main objective transporting idiots from place to place all the other creature comforts aren't necessary. I'm sorry and you know what your elbow can always flip a lever or turn a knob unless you break your arm
