Nice video. Been a while since I've lived this life, at what point are dual needle and seats needed on e85? FWIW I have an old quick fuel blow through in a box somewhere you've inspired me to dust off... I've also got a 468bbc in pieces somewhere...
Hello Great videos, i have a ls 6.0 on e85 blow through and i have the BRPV front and back and i am having issues with getting this carb right. It is lean on the big end (1/8th mile). Do you have a base e85 carb setup you can recommend? Thanks in advance...
jacob bell have you tried netting up in the secondary’s? Do that until you get your AFR then calculate the PVCR increase for the front power valve. Or adjust HSAB to make it pull more fuel. Once you get it where you want it, then look at squaring it up
Hi ! Im trying make a bone stock 5.0 explorer engine blow through I have a few questions Is 750 cfm too big carb? What jets you recommends for a good starting point? Brpv in secondary and a blocked in primary? I just want some fuel economy for daily use
phonypony 5.0 gas over 1000 hp for sure. E85 with the big metal needles some say 700 wheel some make 900 wheel. I was always told 700 wheel so I ran duals. But I have a buddy running 8.30s on singles on e85. And for what it’s worth my old 632 made 937 wheel all motor e85 on singles..... you be the judge
Probably don’t need one for 6psi but that’s a loaded question. If your have a 600hp engine and put 6 psi on it your adding 200hp...... then I would say yes. If it’s a 350/400 hp motor your prob fine
@@tittan1500 ok cool. On this engine it will stay because I will be at 500 flywheel. Much beyond that you split the block, lol. 351 windsor base is in the futture tho.
I take the base off tap the hole from the top and don't tap all the wY threw or do it to the carb body so when you put the carb base back on it can not fall out . Its in-between the base and body nowhere to go!
Hay man got a demon 850 has everything u said in first video except front power value. Want to run e85 in it along with the blow threw what else needs to be done to run e85?
Yup for the average guy who’s not messing with booster and mainwell size If you have annular boosters and the passages are large enough you can crank some good numbers.
This series has come at the perfect time for me diving deep in the world of blo thru carbs
Now I know. The online tutorials over complicate things haha. Good stuff man.
Great explanation I just built a flow thru 850cfm for a 468bbc with a paxton supercharger runs great just need to fine tune thank you
Excellent work.

Matt Bowden some guys day 700 wheel e85 but I have seen guys run low 8s
I Just purchased two of them i can't wait to try them out keep the videos coming 🙌🏾
SEAN PATRICK killer man thank you!
Hello
Great videos, i have a ls 6.0 on e85 blow through and i have the BRPV front and back and i am having issues with getting this carb right. It is lean on the big end (1/8th mile). Do you have a base e85 carb setup you can recommend? Thanks in advance...

Do that until you get your AFR then calculate the PVCR increase for the front power valve.
Or adjust HSAB to make it pull more fuel.
Once you get it where you want it, then look at squaring it up
How does that Loctite hold up against ethanol fuels?
No issues with e85
Do you remove both check balls in the base plate or leave in and tap shallow ?
They need to be plugged so no boost / vacuum can reach the power valve cavity
Hi !
Im trying make a bone stock 5.0 explorer engine blow through
I have a few questions
Is 750 cfm too big carb?
What jets you recommends for a good starting point?
Brpv in secondary and a blocked in primary?
I just want some fuel economy for daily use
If I’m only installing one power valve should I install one or 2 solid floats ?
All floats need to be solid
do you recommend when running a single BRPV to run it on the primary or the secondary? automatic car with transbrake. Thanks in advance
Do I need to do this if I have a pull through roots style blower or is this only for blow through?
Not for roots style
Awesome thanks. So I can just run my unmodified Holley brawler?
If I’m doing a single BRPV would I still drill the secondary metering block to .080? 750 Demon on a 4.3 v6
Keep it stock on a small engine like that and try first you can drill larger but not smaller
What is done with the front power valve
Depending on power you can do a BRPV or standard low vacuum
So like a 4.5 primary with BRPV secondary would work
@@timothygibson6578 yup to a point
At what point do you think you would need to swap to dual needle and seat
phonypony 5.0 gas over 1000 hp for sure.
E85 with the big metal needles some say 700 wheel some make 900 wheel.
I was always told 700 wheel so I ran duals. But I have a buddy running 8.30s on singles on e85.
And for what it’s worth my old 632 made 937 wheel all motor e85 on singles..... you be the judge
what is needed for a low boost 6psi setup?
Probably don’t need one for 6psi but that’s a loaded question. If your have a 600hp engine and put 6 psi on it your adding 200hp...... then I would say yes. If it’s a 350/400 hp motor your prob fine
@@tittan1500 331 sbf with a precision 66mm at 5-6psi. Should I use a BR power valve? Was gonna just use the hanger 18 mods?
Hammer Head Garage it won’t stay at 6psi long so I would get it out of the way now. It makes tuning a lot easier and safer part throttle
@@tittan1500 ok cool. On this engine it will stay because I will be at 500 flywheel. Much beyond that you split the block, lol. 351 windsor base is in the futture tho.
Good stuff, 👍👍
Thanks
Another killer 101 video.
I take the base off tap the hole from the top and don't tap all the wY threw or do it to the carb body so when you put the carb base back on it can not fall out . Its in-between the base and body nowhere to go!
Gr8! Video! Very informative, can't wait until the next one.....
What's your opinion on blocking the main wells? I've seen that done either epoxy or plugs. For E85/methonal blow thru set up. What's the point of it?
Increases suction for the fuel pickup AJS you can move more fuel. Pro systems uses solid blocks and lot of guys plug the holes
Hay man got a demon 850 has everything u said in first video except front power value. Want to run e85 in it along with the blow threw what else needs to be done to run e85?
Adjust the jetting / bleeds / squirters , larger acc pumps and nitrile acc pumps .
Possibly enlarge the main wells
Great info greatly appreciated, what power level do you think these diy mods are good for 8-900?
Yup for the average guy who’s not messing with booster and mainwell size
If you have annular boosters and the passages are large enough you can crank some good numbers.
i love how you say "not a big deal" often.... makes me feel like i can hande this hahah
Dan Daley you got it
Your videos need more views. Great content explained very well
cnebuda Thank you
