Wow thank you for all of the kind words and shouting out my channel. I appreciate it! Let me know when your ready to get this thing back in the dyno!
Will do pimp I appreciate all the help.
Wondering where Joe Simpson is located, I'd love to do work with him,I watch his channel and when I'm ready to step up to boost I'd like to bring my junk to him

BRO! IM GOING THERE TO GET THE NOVA TUNED! Thanks so much! Most def! I hope the guy is nice to me.
That's what David Vizard says "It's what the engine wants It's not what you think it wants"👍
Tyler, has by far the BEST tuning vids on double pumpers when tuning with a wideband . Helped me allot with tuning my 4150 750 Holly Ultra double pumper Proform main body ,on my Ford FE 431 stroker. Always so stoked to see a new carb tuning vid from him!!!!
You have by far the best carb videos with no bs it has opened my eyes to some of the twerks ive done on my 750 brawer. I had a problem with secondary not opening all the time right away from the little link from primary to the secondary needed slightly bent more it was hanging up.
In my experience with carburetors on the street, is they always need to run at least a power valve in the primaries, like you have done. Even if its a drag motor with minimal street use. Otherwise like you have discovered, you have a rich cruise mixture.
Good video.
I have always had better luck too. I have not noticed a different in performance with or without. 5 - 4 sec 1/8 mile cars run them.
I agree you're absolutely right listen to what the motor tells you and what size file valve it needs that is a true statement and always will be first rule of tuning
Thanks for sharing your tuning tips, I'm still running gas and would like to get on with some e85 I'm sure I'll need some help,I used to run hilbon injection and the toilet bowl on alchohol but e85 is new for me,990 is cooking, running great 👍
The 9.9 was with a 357 CID stock DIY ported Gen2 LT1 head. It did have a good bottom half.
You can alter (fine tune) the AFR’s by tuning the Idle air bleeds and the High speed air bleeds.
PV selection is a function of engine vacuum. A solid base PV is to measure your engine vacuum warm, at idle, in gear then subtract 2hg from the observed vacuum. Then drive it and see how it transitions. JD
P.S. Some high stall converters (loose) and manual transmission apps you Divide the idle vacuum by 2.
Carb sizing, if you show vacuum at WOT the carb is too small.
Definitely easier said than done carbs are trial and error in my experience.
@@TPVPRO For sure, there’s a lot of testing to see what works best. Imagine how hard it was for the old school guys without an AFR gauge, fixed air bleeds etc! Dang
@@HeadFlowInc No doubt you got to have a good 👂. Tuning time is cut in half but I still use the plus as church in the end.
@1:47 and paused. Put a power valve in it. All 4 butterflies closed. Drill the butterflies on the idle/transfer circuit slot side but in the center near the shaft. If you start turning the adjustment screw to either primary or secondary you'll get into your transfer circuit and lose fuel mixture control. I've started at 0.125" on all four butterflies in 950cfm 4150 carbs. Let your initial timing determine your idle speed. Limit total timing where you want it via bushing size. Have all your advance in by 3k RPM. the air bleeds may need a change.
Oh yeah, fuel pressure no more than 5lbs.
spot on, I went through a lot to learn this, good input
@@robertkitchell859 yeah, it's one of those ancient Chinese secrets. I hope this dude reads and takes my advice. I've recently taken a Proform 950 that was "set up" by Davinci with jets 10 sizes too big, no power valve, improperly sized air bleeds, and all the butterflies installed upside down(they're beveled to sealed at an angle) on a 496 BBC NA 13.5: 800fwhp drag motor that idled at 1,200rpm and gave it street manners. Reliable daily driveability. Well for 2 hours at a time. Fuel pump limited to 2 hours of run time.
All jokes aside keep up the good content! I agree with you sometimes we just have to try everything in order to know that’s why we test
With E85 having a stoichiometric ratio of 9.7:1 it’s going to run rich on a gas scale gauge of 14.7:1 stoich. Use lambda scale to reference from stoich.
This. Most of the time you're gonna see somewhere between 10:1 and 12:1 on e85. It has to run way fatter than regular non ethanol fuel since you're pumping in something like 30% more fuel volume.
On a NA motor running no power valve is a no no, simply because the power valve channel restriction is for tuning WOT not just acceleration, idle feed restriction is obviously for idle to transition and main jet is for transition and cruise, without a power valve you will have no way of leaning at light load throttle openings, most times I see power valve deleted is to compensate for insufficient main well flow with Ethanol or Methanol conversions as they are too lazy to remove plugs and enlarge main well sizes, on alky blown engines power valve delete is usually done to prevent artificial venturi vacuum signal closing power valve at WOT due to high air mass flow thru carbs and leaning fuel curve at top end. With alky conversions and factory alky carbs the emulsion tubes are also removed from main wells to increase flow through main circuit as well, I've even seen the accelerator squirters check ball left out so it induces a syphoning effect at high rpm to supply extra fuel when main wells cannot flow enough but that again is a crutch like removing PV on NA motors, done right it should drive like on gas with a variable fuel curve
Disregard my my deleted comments I replied to the wrong comment.🤦🏼♂️ You get the PV.👍
Just about to get in the E85 carb world and glad I found this channel!!
That's what I like about your videos you're so thorough explain so much and I have learned so much don't change your ways keep them coming
Banged 8200 quick, hell ya.
Great tech. Hope your 4 legged baby is doing well
Get rid of the screw on jet extensions and use the brass tube type the press on over the jet. The screw on type start to restrict main jet flow at larger jet sizes like you’re running
My mannnn hope all is well with family and ure pup
Wow just the video I needed to see. I have a 427 60 over all good parts afr heads Howard's roller cam srp 11to 1 pistons good rods gm steel crank but I been wanting a 400 or 406 well I found a 406 and it's set up for a 250 shot of nitrous the motor been decked and was just freshen up about 20 passes ago the guy claims with the iron world product heads that have been ported to the max with 64cc heads the compression is 121/2to 1 so I was thinking about running e85 and it looks like with that power valve added to your carb you truck is happy so I think that's the way I will go this motor has a solid roller cam and for the price 2k he has that in parts so I could get my money back out of it if I don't like it. Love your videos I been watching you for a while 2 or 3 years keep up the good work. And thanks
No problem brother there are a lot of opinions on how it should be done. I say test test test find what works best for your needs.
I have a 400 also that I am having problems with a carb set up to definitely help thank you
Pretty cool and really informative video. And already looking forward to when you switch to EFI and have Joe help you tune it along with the follow-up when Joe helps you swap the nitrous for a turbo or two. 😁
I'm thinking about it if I get more views I can. 😆
Good Video my brother
Thanks for the video! I just want to make sure I'm on the same page with you and Joe Simpson...
With the wideband reading on the gas scale max power would be found in the 12.5 -13.2 range for pure gasoline and 10.5 -12.75 range for E85. This would put Methanol in the 9.1 - 11.0 range on a afr gauge using gas scale?
Have a mustang transitioning to methanol and just have a gas AFR gauge in it. I prefer tuning in Lambda but this gauge only displays AFR
10.5 is really fat with E85 on a gas scale. The O2 is still lambda even if it is saying 12s on a gas scale it just takes a lot more E85 to hit 12s. But if you switch over to a lambda scale there will be zero confusion. look at the plus to confirm WOT fueling that will not lie.
@@TPVPRO thanks for the reply. No doubt the plugs don't lie! I figured 10.5 was still pretty fat for E85 but was under the impression that it would still make peaked power at a richer mixture albeit at the expense of fuel mileage. Just thinking that might be a reason the carb was originally setup richer if the tuner wasn't concerned with mileage but just being in the max power window for the fuel.
@@YerkitRacingChannel I had fuel in the oil it was so fat before the change. I would not suggest running it like that or you will wash out the cylinders.
@@TPVPRO good to know! I'm planning on running E85 on my lt1 build at some point. I will keep that in mind!
Go race go #!!!
Awesome video thanks for info . What fuel ⛽️ are you using when the nitrous hits ?
Oh god that is intimidating as hell. Just knowing at any time you can end up with an oil pan full of gas. Better check the oil every time you go to crank her up. Seems like a nerve racking thing. Is there a way to shut off the fuel to the carb before shutting the engine down; to empty the carb out?
Awesome build man!
Man I had to watch this again your Lil truck is rolling.
Great video man, thanks!
Good content buddy
I always run PVs
they also make adjustable power cables that are all metal
Unlock the distributor. I do this 4 days a week. My phone rings Monday morning and I make appointments to improve driveability on carbureted engines. On Friday I count my money and enjoy the satisfaction.
Maybe I missed it but how much did you reduce the jet when you added the PV? Seems like E85 would require more squirter than 29 0n the secondary especially as fast as you're opening them with progressive linkage.
All depends on the carb I just did and video check it out very different from this one.
Stoich for E85 is around 9.8:1 .. 12:1 on E85 is a little lean
Gauge is reading gasoline scale, not ethanol scale
Talk to Paul at SCS carburetor.
I don’t know bout you but if Jesus Christ tells me to do something am going to do it he’s the boss 😂
Isn’t you’re afr supposed to be way richer on e85 anyways ? That part always confuses me
Power Though HP Family TY
how much difference between in mpg gas/e85
That guy squares everything, carb jets, nitrous jets etc... lol
isn't the air fuel parameters for e85 supposed to be 850s instead of the 13.1 for gasoline??Also, I have learned with E85, you should use 1oz per gallon of top lube or the green E85 fuel treatment, if not, you will see corrosion in the fuel and carb after only 2 or 3 days of sitting, the additives puts a stop to that
I see this a lot, every wideband is lamba but the scale for the fuel is different. For E85 to reach 12.0-12.50 it requires a lot more fuel so the scale is different but the O2 doesn't care about scale so it will be almost the same on a gas scale. Hope that makes sense.
@@TPVPRO thanks for the response, helps me greatly, I have a small block 355 on a 150 shot, do you use e85 on the spray or gas??
@@robertkitchell859 I have not got that far yet.
Hi, Have you ever done a video gas to e85 swap say on a Holley 750, the conversion kit they sell? i'm thinking about doing it for my jet boat since gas is high AF in cali,
I have not you also need to change the boosters "Larger"
sir appreciate ur videos , trying to figure my c;r 11.3 on my 3.75 .060 lt1,should try to e85 it,maybe boost c/r gap rings etc, running f/i, dont want to to run prem fuel. what say u sir?
might run nos, later before world ends
PS I forgot something SMH soldiers on the front line what's going on take a look at them if you know what I mean I believe you'll get it but don't forget soldier four and six and five and three always going to be a little hotter but pay attention to the other ones lol
What kind of AFR setup do you have?
It's a older Auto meter they don't make anymore. I am going to be sad when it takes a crap.
What’s fuel pump you using ?
👍🏾💯
Here's the problem. You cannot buy any carb ready to bolt on for street and strip. I bought a QFuel 750 e85 for my 355 drag car which runs on the street a little. I can tell you more about it now than i care to know. First it was too small for e85 as i kept pulling back vacuum as rpm increased fast, which i have to say is attributed to 5.13 gears. I jetted, changed mab's iab's took the power valve out. Got it to run very well only was still a little fat. Too small a carb with e85 gives you problems. I took the 750 modified it for the 850/950 base and walla of course it all changed but i kept getting closer. Biggest problem is off idle and cruise, this is where your power valve can help as you can never quite get the idle and t slot right as you have different vacuum levels on this circuit. I did notice your carb has the t slot restrictors in it. That's a good move to solving some of the idle / cruise problems. Now keep in mind the sec idle t slot circuit is still involved with a certain amount of your cruise except with the 1 to 1 linkage. You starting to get the picture? There's more than one way to skin a cat. I haven't even gotten into the emulsion jets yet. In conclusion.. I really don't think Mark is your problem, one has to tune every engine based on what it needs for what it's entended to do. You're doing 2 things that work pretty much in different directions. As to Mark, I have never met him never used his carbs, only read his long list of information about e85 carbs. Several of my racing clients have used him without any big issues. Ps. In order for myself to give you any better info one needs more info. Like have no idea what compression ratio you have. If you r 13 to 1 I think your leaner than i would like at times. But also i prefer Lambda to AFR as it is more accurate especially when fuel is not consistent. A ps. to my ps. You cannot check the moisture content in your so called e85 with that little checker. Your alcohol can be saturated with who knows how much water? No carb tuner can account for that big difference. Good luck with your project.
Make a video all easier said than done.
@@TPVPRO Not sure what make a video has to do with anything I posted. I just think you're expecting Mark to build a carb that you can practically bolt on in a racing yet street condition. Obviously your intent was to down grade his work. Perhaps you didn't give him all the info he needed. A lot of younger people lack the understanding when it comes to carbs. Maybe you aught to make a video on how to WHINE! I think that might be your gifting!
@@havebenthere You should just stop because you are outside looking in and don't know half of what went down. I love people like you all you do is motivate 😘.
@@TPVPRO You're the one who posted the video. I was merely giving insight to what all is involved in e85 carb tuning. If you don't want anyone looking in then don't post videos tearing down a carb builders work. You could've not mentioned Marks name and I would've posted what I did without mentioning his name either. Obviously you have an ax to grind. I don't as I wouldn't know Mark if he ran into me. If you can't take the heat get out of the kitchen!
@@havebenthere Don't bother me pimp you are not the first and you won't be the last.
That's a screaming sbc you have their sir
on E85 your AFR should be around 9
Not when your wideband is reading on the gasoline scale
@@JoeSimpsonAtTempest gasoline scale ? there is no such thing as a gasoline scale for E85
@@widowmaker4618 Your literally watching an air fuel gauge in the gasoline scale in this video, how could you argue what your watching with your own eyes?
@@JoeSimpsonAtTempest gasoline , E85 , ethanol and methanol require different AFRs unless you tune ot your specific fuel your car will not run at its best if you set your AFR gauge for gasoline then when you switch to E85 your AFR will read for gasoline but will not show the best AFR for E85 E85 requries a AFR of around 8.5 to 9 to run correctly a lambda scale is more accurate way to tune
@@widowmaker4618 you are completely wrong. All afr meters read lambda then convert lambda to the scale of the gauge. In the case of this wideband it reads on the gasoline scale.
If this wideband read onthe ethanol scale then you would see ethanol based numbers. But it’s not so you don’t. If you ran this at 9:1 with the wideband in the car it would spit and sputter and run like a pile of trash.
Jesus usage is higher octane believe it .roors like a lion 🦁kick like a 🐴 ha ha.
Leave Jesus Christ out of that! Foolish
I am sure he can take a joke.
Hey just watched your video. I had similar problems when I went blow through e85. Pro systems did the carb. I never got it right and sent it to Eric at horsepower innovations all he does is e85 carbs. He is great to work with answered anytime I called and it was very close right out the box took to dyno he told me what to adjust after each pull and got it spot on. What's your email or phone number I'm in northern VA go to mri alot. Hope all goes well good video
I wish i could find someone like this in PA. To help or give me some guidance on tuning the holley 750cfm for the weiand 174 setup i put together. I enjoy the videos.
