Making Big Horsepower on 93 octane: MIXED UP BOSS is Alive!!! The Hemi headed Smallblock Ford

Today on Unity Motorsports Garage, I'm rocking my new ‪@theoldmansgarage‬ Shop shirt While on the search for Big Horsepower with 93 Octane pump gas! After the big ignition system fail, Progression Ignition saved the day..( more to come on this) We we're able to finally make some numbers on 93oct. pump gas with MIXED UP BOSS The BOSS 429 Style Hemi headed 429" Stroker Windsor! We have more tricks up our sleeve so Stay Tuned
Special Thanks to Dennis and Greg from the Race Engine Challenge Dyno Facility in Charlotte NC for helping me find All of the Power!!! ‪@UncleTonysGarage‬ get that Ghostbuster ready...

Now that was info packed and a eye opener for people that haven’t been to the dyno room in the procedure and time it takes to hunt for a great running engine. Thanks Andy, well done.

[@UnityMotorSportsGarage]

Thanks Rob! I wanted to show what all goes into Dyno testing... There is SO much to it that doesnt get shown even here on youtube! Thanks for Watching Andy

[@johnshackelford6965]

If it was easy to do?

[@jamesroberts807]

Happy Happy Happy birthday bro. Hope you had a great day

[@UnityMotorSportsGarage]

Thanks James!! its was a good one.. Andy

[@deanstevenson6527]

Formula 1 engineering rule 101 from the late Keith Duckworth. For 780 HP at 7000 rpm, and a perfect intake with perfect runner intake volume per cubic inch, with zero flow from blocked off PVCR.... you'd get away with eight 59 Holley jets and 316 cc/min fuel flow from each of those. 2.527 liters of fuel flow makes exactly 780 HP. The wetted perimeter is a total surface area of gasoline boundary layer. That will chop and change your air fuel under load. So feel free to drop down fuel levels, and peak pressure. A Hemi head is a much more vibration prone combustion engine, so finding Power might require some staggered jetting to get flat fuel delivery to each cylinder. Haywire responses can be dialed back by air bleeds. Whatever works.

[@johnelliott7375]

Thanks Dennis and Mr. Finnegan, I will be rooting for you and Pop said more air LOL. Great day to you Andy! Congratulations on your 429!🎉😉

[@toddmccarter45]

Happy birthday Andy!

It was! To hear MIXED UP BOSS come alive after 2 years was a great feeling... Thanks for Watching Andy

[@jeffalessi]

Don't Mess With The Boss!

[@jimgould2829]

8 smoking hot barrels of Holley carbs on top of a tunnel ram feeding a Boss headed small block Ford woohoo!!😮🔥🥵🤯That was a real treat for a Ford fanatic to say the least🤠Fabulous job sir Andy!!You're one heck of a engine builder and carb doctor!!The tons of research and hard work you did are really showing up in the end on this incredible build!

[@UnityMotorSportsGarage]

Thanks Jim, this has been a long time coming! Hopefully I can squeeze a bit more out of it before I bring MIXED UP BOSS home! Andy

[@FredMiller-lf2fj]

If you want to stay old school then why not ditch the carbs and use a mechanical injector? Like maybe an Enderle shotgun injector? You can weld injector bungs right at the port entry resulting in a "dry air" manifold. Way quicker to tune, especially with a "Dial-A-Jet" cheaper than those Grossly Overpriced Holleys. Just remember to get a mechanical injection pump like a Hilborn or kinsler dash 1 or 2 type. With a Dial-A-Jet you can lean / richen the whole system at the turn of a knob / lever even while running on the highway with the throttle barely cracked open.( Part throttle cruise) . Just a thought.

[@johnelliott7375]

[@maxwedgedickdasterdly5586]

Cant wait to see her run down the track ! I loved your comment dual carbs are like a beautiful women. The trouble makes it more than worth it. I smile every time I open my hood and see a Cross Ram. I like when young guys see dual carbs and ask what are those . Lol

[@doctorromex7804]

Concerning that rich condition. After pondering over it, watching the actual dyno sessions then pondering some more. Did you ever consider lowering the float levels to about 3/32 below the sight holes and stepping the fuel pressure down by 1 1/2 to 2 pounds and making a pull. The amount of theoretic jet that you pulled out and showed little change doesnt really jive in my head knowing how close out of the box calibration usually is on a Holley Carb ( I know taking the tunnel ram into consideration changes things a bit from single 4 applications) I also notice that that dynomometer exibits some vibrations that may translate into some harmonic frequecies that are transfered into the fuel in the bowls which if the fuel level is somewhat high (for dyno purposes) coupled with more than necessary fuel pressure may cause the carbs to do something called "Pull Over" which is extra fuel syphoning from the venturis as the rpm and vacuum rises. The orientation of the carbs (sideways) coupled with everything else I mentioned may be a contributor also. Also as a side note: Notice the fuel vapors emitted from the carbs barrels after you shut off the engine, that has raw fuel written all over it. ( Which may just be a tunnel ram thing ????) This is just my two cents and food for more thought. Keep up the great content.

[@doctorromex7804]

@Made By Nobody Famous That wasn't what I was implying. Just consider what happens when the float sticks in a carburetor and the float level reaches the point where fuel is above the level of the booster tubes.....regardless of the size of the jet you go into a full flood condition because you loose any ability to meter the fuel supply. A carburetor relys on the suction created across the booster in conjunction with the air bleed size to pull a certain amount of fuel thru a certain size orifice (the jet) allowing precise metering of the fuel.

[@shakeydavesr]

I swear, I've learned more about carb tuning today, between the video and comments, than I think I've retained in the last 30 some years,,,, lol . Some great input from comments.

[@logan_e]

It's possible. If the fuel pressure is too high it can overcome the ability of the float to close the needle back into the seat. Most people don't realize that while the engine is running the float & needle don't shut off the fuel flow 'then open then shut' etc etc, the float and needle find a steady state, allowing just enough fuel to flow to replace what's being used continuously, not stop & start. If the pressure is too high it can force the needle open and overfill the bowl, causing spillover through the booster and a rich condition.

[@DragBoss351Cleveland]

Andy great video and lots of work. Casper watch out. Torque is 👑

[@UnityMotorSportsGarage]

Thanks Brother! I'm making some progress...things are looking good... Andy

[@jimm8264]

Thanks guys. Awesome work.

[@johnflett2531]

Had the speakers turned waaay up whole time! Love seeing all the details in dialing it in! I'm very interested to see what is causing the #4 lean issue. It's weird because #4 doesn't have any holes firing around it, looking forward to see what spacers do for it. Make sure to bring lots of different spacers to try.

[@JasonsGarargeInc]

That is one sweet sounding power plant man!!

[@TheRdub82]

I would've thought the tunnel ram has more plemum volume than a 4500 intake. At least your tuning AF ratio per cylinder. Hope you find 700+. This engine would definitely do better with compression and E-85 🌽. My TFS R Series headed 430W with a ported 4150 made 716/592 and those heads aren't moving as much air as Kasse heads. Interested in final numbers. Either way this is a stout combo!🏁🔥

[@UnityMotorSportsGarage]

You have to remember it's going in a 4000lb truck.. my approach would be totally different if it were going in a light car... It's going to be street driven daily, so it has to go the long haul! Thanks for Watching Andy

[@georgemartin7219]

Andy I have a small block ford with a dual quad tunnel ram and one inch custom spacers made and dyno tuned by Terry Walters ( I think you might know him) and the spacers made a huge difference on mine. now I need me a set of those BOSS 429 style heads.

[@georgemartin7219]

@@UnityMotorSportsGarage I think it will surpass that 700 mark with ease, good luck.

That is such an impressive thing to behold. From the valve covers to the iconic tunnel ram and the two 4’s on top. It’s a thing of beauty. And on top of that, the knowledge that you have is just as impressive. Be very happy that we aren’t neighbors… I would make you insane. Great video Andy, looking forward to the next one!!

[@UnityMotorSportsGarage]

Thanks for the kind words! The Dyno is always a good idea.. you get to try things in a controlled environment and you can find problems before you install it in the vehicle! Like my leaking oil pan... Not to mention you can break the engine in under a load to ensure that your ring seal is good to go... I agree finding the lean cylinders is a huge plus! It would have been bad to find out the hard way.... Andy

Yes, it is true a carburetor can do everything that fuel injection can do. However the pad to get there is so much simpler with fuel injection.
