Fuel pressure sensor sends a low pressure signal to the ECU so the ECU pulls back boost, timing and.... fuel? XD. Just had to throw that out there, good videos, I'm thinking about buying one of these that I will eventually be making changes to. These videos are gold for realizing what I will be dealing with, thank you.
Thanks John for taking the time to give us such an exceptionally detailed explanation. Your unwavering commitment and drive to get the most performance out of the Stinger while keeping it as dependable and reliable as possible is exemplary. That's how you build a great reputation and a trusted brand. You definitely have a future customer here once you sort all this out. Keep us posted!
Keep up the great work, and informational videos John. I have a feeling I'll be running your stage 2.5 tune by the end of the year, and now getting a new fuel pump lol.
My check engine light has been on..seems the fuel level sensor has a short. Id assume its because i kept it below half for a few month's. Thanks for your effort and research.
Good to see you back John. With the extra HP it only makes sense that you will need more gas. How about adding an external gas tank and pump temporarily in the shop to get some data from the dyno pulls to see if its even going to make a difference at all. Especially before you add the Methanol.
Add an extra alternator power wire to the fuse box and extra battery ground to the frame and extra ground from engine block to frame to increase voltage on the car's electrical system overall then make a thicker gauge wiring harness from the fuse box back to the fuel pump and you will have more voltage and more flow on the factory pump!
@@TorkMotorsports just a thought but it does look like it's slightly different. Maybe a way to use the same pump and fuel sensor with the v8s housing and and piping. I cant tell though from pictures but they're about 80$ used might be worth a tear down.
What is with the ribbed hoses? Does that not create turbulence and air pockets for the pump to contend with ? Wouldn't a solid line help with a consistent flow of fuel ? Your the man,I'm just asking...
From what I remember during engineering school it creates little vortexes thus it actually increases flow by a little bit. Most of your flow is actually through the center of any pipe. Even smooth walls create "drag" on the fluid passing through. So the ribs allow those vortexes to happen and actually increase flow by some percentage not much but it outperforms a smooth pipe of the same OD IIRC.
But doesn't there have to be an intake return line anyway because its return less so that fuel wouldn't be used anyway it would just fall back into the tank it seems like that is the fpr and the thing for the crossover
It seems that your wanting to stay within the stock configuration.A simple solution to me would be a dual feed into a single feed line with a pump that generates way more then needed then an adjustable regulator before sending into the system ? Or does that not Float pun intended being that it's injected... ;)
Also operating that pump to it's limits every time you have a bit of fun.I can't see it lasting very long and replacing it every few weeks or months takes some of the fun out of the gain unless you have your own shop and even still if it fails when you have a dollar or two on the line it makes it much less fun...
Still working on a solution. The 4 wire in tank fuel pump I suspect is the culprit for our fueling problems right now. Also... the basket that fills with fuel is suspect to get sucked dry by the current commanded fuel request. The only solution to this would be a twin pump hanger, and you could never let your car run below 1/4 tank with a set up like that.
So curious with all the mods you guys have done. Stock on the dash there is a oil temp, boost meter and torque meter. What happens once you added power? Does the torque meter just peg out or are you able to extend limit to see a reading? Want to definitely do some upgrades on minr but was curious on that. Also how does it drive in the different modes? Does comfort still feel the same or is there more punch in that mode? Also in eco mode? Or does the additional power only show in Sport mode? Guess that's more my question. Would be nice to have the lower modes to react the same and only have sport mode adjusted. How does it work?
I'm assuming the genesis g70 will have the same issue? Crap. Still making a pretty acceptable amount of power with your tune though! (Wish I had either a g70 or stinger next car goals)
Looking to run full E85 on a better pump? Will you have to over compensate on pump to factor in that 20% loss to the second part of the tank? Is 600hp in the future??
Great video and I like how you broke it down for even a newbie to understand. Will you be testing the new fuel pumps exclusively or with the methanol systems?
If the fuel pump is all ready at its capacity then the injectors are not far behind. I really would like a stronger pump. If you run the tune the way it is the pump will fail prematurely.
Would an in-line pump cause problems with the low pressure sensor? Or could the low pressure sensor be moved upstream of the upgraded inline fuel pump? Possibly add a pump from the secondary baffle/tank feeding the primary baffle/tank. Eliminate the Venturi setup. That would free up some fuel. If you have a pump built with larger outlet and higher flow that should eliminate a lot of loss and increase your volume. Or a combination of all the above. But if the low pressure se sir can be moved upstream of an inline higher volume pump, that might eliminate that from being a problem.
I've been missing the Stinger updates. Thanks for all you provide to us.

We are still logging the parameters to figure out what the car is doing.

Can't wait for a solid solution or aftermarket fuel pump! Keep up the videos!

You are welcome.
As always, great information John.
Damn dude...miss the updates. Glad to see you getting it done though!

We could do that, but the work required would be insane
Excellent... Very informative...Keep up the good work.

It is always the little things isn’t. That was great info, to me anyway.
Cheers
This just shows the need for aftermarket parts manufacturers to get involved.
*Shows two problems*- "but thats not where the problem is"... me- "oh jesus" *tear goes down face*
Weird question..... did the v8 engine from the k900 have the same fueling system 🤔.
Unknown, but I would have to say its similar.

Problem with a system like that, we have a fuel.pressure sensor that we need to deal with that is built into the fuel pump housing.
I must have missed some of the new posts. So did you have a new high pressure pump built or did you find a work around.
Still working on a solution. The 4 wire in tank fuel pump I suspect is the culprit for our fueling problems right now. Also... the basket that fills with fuel is suspect to get sucked dry by the current commanded fuel request. The only solution to this would be a twin pump hanger, and you could never let your car run below 1/4 tank with a set up like that.
Is there a build list for this Stinger?
Yes, on our FB page.

Yes, toque meter pegs out. It drives fantastic in all modes.

We are looking at ethanol options.
Unfortunately you would need to account for 30%-40% for gains. You would also have to address the injector size as well.
What would you say the best mods for an Elantra Sport are if on a budget and wanting to keep reliability/stock boost level?
A tune.
Great video and I like how you broke it down for even a newbie to understand.
Will you be testing the new fuel pumps exclusively or with the methanol systems?
Both with and without the methanol systems.
Thanks for the info, so you have maxed out the fuel pump?
We have started to see pressure falling off with the higher commanded boost levels.
If the fuel pump is all ready at its capacity then the injectors are not far behind. I really would like a stronger pump. If you run the tune the way it is the pump will fail prematurely.
Actually, the injectors have a ton of room left in them. We also have a lot additional pressure that we can run on the high pressure fuel pump.
Would an in-line pump cause problems with the low pressure sensor?
Or could the low pressure sensor be moved upstream of the upgraded inline fuel pump?
Possibly add a pump from the secondary baffle/tank feeding the primary baffle/tank. Eliminate the Venturi setup. That would free up some fuel. If you have a pump built with larger outlet and higher flow that should eliminate a lot of loss and increase your volume.

490 crank hp if your wheel hp is 460..... wtf? lol.
I think its more than that.
460 + 15% should be around 530 crank HP.
@@TorkMotorsports no, full stop.
Anyone else notice the fuel sock looks like Michigan? XD
Great vid John! Cant wait to see meth in the shop car. You going to run a snow kit?
Yes, we try to run snow systems on all the shop cars.
It's been so long since your last update they discontinued the stinger 😮 just kidding 🤪
LoL
