Fair warning: This is a long one. But there’s so much to talk about when you get to go hands-on with an 11,000-hp supercharged Hemi V-8 from Tony Schumacher’s U.S. Army Racing Top Fuel dragster! We suggest you grab a beverage and get comfortable while Hagerty’s Davin Reckow and Ben Woodworth sit down to discuss the finer points of this nitro-fueled monster, which was featured in our latest Redline Rebuild time-lapse video. We did our best to answer all those burning questions you had, but let us know in the comments if we missed anything.

The beginning says it all. Just looking at the size and knowing what that engine is capable of absolutely send chills down my spine.

@robertsilva5041 4 года назад

Those 3 walls in the block was definitely a great idea when that block was made. It definitely increased the strength in the valley area where the lifters are. Very impressive... I pushed a 302 to it's max and that's where it failed. Love this motor!!!! Well designed

I've fiddled with engines long enough that the tip of turning the block 90 degrees on the stand in order torque down the bolts hit me as the most epic "doh" moment ever! From this day forth, it shall be law in my garage to always rotate the block for torquing.

@dmeemd7787 4 года назад

Another cool thing from when I worked on these is you don't need a number one main bearing at least not at the other big-name team, due to the blower belt tension and the back of this not in the middle of the engine. Lot of very smart people that's for damn sure! Also the amount of distortion the crankshaft has during a run, they were talking about possibly putting the crank trigger on the rear at one point, I wish I remember how many degrees it would twist the crank but it was a pretty ridiculous number that you wouldn't think would be possible

Uh, and just like my current TL and Toyota engines, they do it for 300K + miles, without being opened once, right? There are other aspects that need to be put in context, as well. And compared to a turbine of the same size and weight, it produces relatively little HP, actually, and they do it for about 18,000 times as long. Pound for pound, compared to a rocket engine, it produces basically nothing. Just sayin'. ;-)

@sputnik16335 5 лет назад

It's a typical Roots-style blower. A typical misconception is that the rotors rotate toward each other and the air is pulled down between the lobes of the rotors. The rotors actually rotate away from each other and the air is pulled to the outside in the voids between them and the housing.

I’ve been privy to quite a few forms of racing; Sport cars, Indy cars, F1 cars, Shifter carts, NASCAR, Outlaw sprint cars, Supercross, Flat track, Hydroplanes, Drag boats, even Military air shows. Not many were as up close and personal as NHRA. Ten years ago it was a ritual for me and my brothers to make it to HPT twice a year. It is def an experience to witness the pure violence of these cars on track. For the many friends I’ve taken along; the first pass they witness just leaves them in stupefied awe. It one thing to see the launch, it’s a whole another thing to witness these cars at the top end. This video was great to really see the nitty gritty of the build. My only complaint would be, I wish they would have us not watching it over their shoulder, full screen shots instead with voice over.

@rextripod6242 5 лет назад

@59.00. I have a great story to go with that... my rookie year of drag racing I asked Jim Dunn the same question ... why don’t we bolt the heads before we leave the track. That way we have more time in the morning instead of thrashing trying to make it to the lanes.... Jim said .. you want to bolt them on then you do it .. both sides... I jumped in and bolted on both heads then we finished the motor adjusted the valves and put the car away “ready” for the next day.. I went to bed that night tired but knew the car was ready to start in the morning.... we showed up at the track the next morning and got the car out and our pit area set up... Jim showed up walked in the trailer set his stuff down came back outside and walk right up to me and said...... CHANGING HEAD GASKETS....... then ... I understood.....lol

@MattyT_86 5 лет назад

seems like a shitty thing for him to have done just to make a point, rather than say "well, actually we like to check the atmospheric pressure etc as close to running as possible so we can tune the compression with the head gaskets. If you put it on now, we might only end up taking it off again anyway tomorrow before we run"

At John Force Racing (and these are basically the same) the funny cars have an external oil tank where the dragsters keep it in the pan below (they have different oil volumes as well which is cool since it's the same engine) even though it still has an external pump. A lot of people say one is dry-sump one is wet-sump... but like he says here, you have an external gear pump so not exactly, lol -- so very cool that he got to experience this and properly go through everything :-) Also rad it has as many views as it does, I wish I had more though! This is great stuff, love it!

@billclark5943 6 лет назад

actually the mid plate is what holds the motor in the car and carries the bulk of the forces. It's bolted in. the front mounts saddle the frame rails with "hose clamps" but are mainly to hold the weight of the motor up in the front

Heh ... Not to nitpick, but at 38 minutes in, you're describing how the blower works in reverse. The air doesn't flow straight down and get compressed, but rather around the outside of the lobes. It's kind of counter intuitive. Like I said, a nitpick, but thought I'd throw it out there (I'm sure someone else has pointed this out as well). Lots of great info as this is way too cool!

@DirtRoadie 5 лет назад

His comment at 1:07:53 is a little strange too. What is so baffling about blower speed being geared to be a bit faster or slower? It's just a pump.

@231mac 5 лет назад

DR - Blower speed dictates how much air will be pumped into the engine, relative to engine RPM. Obviously, the more air pumped in allows more fuel to be added, equalling more power... sometimes. If the air is 'bad', meaning high temps and humidity, you can actually make MORE power by slowing down the blower speed.

Did I miss your run times on this build? Was waiting for that most important piece of information. I was at Portland International Raceway years ago when Big Daddy Don Garletts set a new world record in the quarter mile at 4.3 seconds I believe it was at just over 300 miles per hour. Now that was back around 1975 and why I was interested in the times here as a comparison 43 years later, one would think the technology in engine rebuilds have advanced quite a bit since then and reflected in the speed and time numbers, bottom line. I remember back then being blown away at that record setting day for Don, and still can not imagine 300 miles per hour within a quarter mile, it is both amazing and exiting for even back then. Thanx for the video, Always was curious at what went into one of these builds and to see how it was all done for one of these monster engines, well worth the time to watch.

Eddie Hill...At the 1987 Chief Auto Parts Nationals, where he was runner-up, Eddie Hill set an NHRA record of 285.98 mph On April 9, 1988, he set the first four second elapsed time (4.990 seconds) at the National Hot Rod Association (NHRA) Texas FallNationals in Ennis, TX. Hill made the run on only seven cylinders Kenny Bernstein....In 1990, following a change in NHRA rules, Bernstein began to drive in the Top Fuel Dragster class. Two years later, Bernstein became the first driver in any class to exceed 300 MPH in competition, Don Garlits....Garlits was the first drag racer to officially surpass the 170, 180, 200, 240, 250, and 270 miles per hour marks in the quarter mile; he was also the first to top 200 mph in the 1/8 mile. His last qualifying race was in May 2003 at the NHRA POWERade Drag Racing Series, 23rd annual Summit Racing Equipment NHRA Southern Nationals presented by Pontiac in Atlanta, Georgia. At the age of 71 years, 5 months and 19 days he qualified 16th, setting a personal best speed in the quarter mile with a time of 4.788 seconds at 319.98 mph. Garlits had reached 323.04 earlier in the year at the 2003 Gatornationals. Mr. Garlits lost in first round competition with his Summit Racing-Mono Winged Dragster, clocking in with a 0.064 reaction time, a personal best 4.737 elapsed time, and 307.44 mph

@johnd9357 5 лет назад

He says that nitro actually has more energy than race fuel. That's not correct at all. Nitromethane has LESS energy density than even regular old pump gasoline. The reason nitro is used is because it has a lower stoich allowing MORE fuel to be burned for the SAME amount of air pumped in. More fuel = more power output. Nitro simply burns better with less air because it has an oxygen component in the fuel itself. It absolutely doesn't have MORE energy density than gasoline however.

@JoeSolo814 5 лет назад

Great point! Nitromethane is definetly the #1 misunderstood fuels to anyone who never actually tuned or ran a Fuel engine. To this day it's still Voodoo to many people. Guy's don't realize it makes it's own atmosphere, and can NOT be lit with a match. It needs the compression, AF ratio, and ignition timing to light that flame!! Nothing on this planet like it!!

@nhraguy532 5 лет назад

Yeah, those are the lines for the down nozzles.

@Over_The_Top-1320 3 года назад

They are for fuel delivery. These are the Cylinder head down nozzles, one constantly sprays fuel while the mechanically driven gear pump is on/open. Each sprays directly at the top/back side of the intake valve internal the intake runner of the head. Both nozzles have adjustable orifice jets threaded between the Stainless lines and the brass down nozzles bodies. One of the each pair is considered to be the idle circuit due to it constantly spraying or on. The second of each pair has a check ball with adjustable spring rates to prevent it from spraying at idle ONLY and possibly “putting the cylinder out” which potentially increases the possibility of hydraulically locking a cylinder and the resulting explosion. The check ball equipped nozzle unseats instantly once OFF IDLE via fuel pressure increasing relative to RPM increase of the mechanically driven fuel pump. This is repeated for each cylinder @ each intake runner of the intake manifold. + 4 nozzles spraying directly into the top of the supercharger (which helps cool its rotating internals, as well as fueling all 8 cylinders + 6 more nozzles in the carbon fiber injector atop the super charger (again to cool and fuel) This is how you squeeze 100 Gallons Per Minute of NitroMethane into 500 C.I.

Intake Valve Nozzles. 2 per Valve. Entire Fule system is driving off the 4 Stage pump. 1 line feeds the Blower Injectors and 1 Line splits and feeds the heads. Regulated by Jets in each injector. Not all cylinders get equal fuel because that's how these things are. For instance we ran 6 different compressions on JRs Top Fuel. So that was 6 different fuel volumes.

As far as I know, nitromethane has 1/4 the energy as gasoline. But because it has a built in oxidizer for the combustion, one can burn 8 times as much as gas. Thus it can make about twice the power.

I had a Honda 750 Chopper built in 1969. It had Weber side drafts, and an ARD belt driven Magneto on the side. That thing was so hot, I put a set of brand new ngks in that bike, in a week and a half later it would melt the whole electrode arm off the plug! That bike was hot and had a cam titanium valves and keepers, a big huge clutch custom chain 906 kit, and it was built in the late sixties. Good times, good times

Get a repaired one. Teams only repair them x amount of times. Windowed blocks from Rods Kicking out . Deck and Heads get Torched from Head Gaskets pushing out. After several runs Blocks get " Out of Tolerance" and can't be CNC'd back into "Critical Tolerance" anymore.

Love that rag around the crank hack. Definitely gonna steal that one. I'm sure I will get a ton of responses from people who are smart enough to have already known that but I have never seen it. I grew up doing homework at dad's tool box in the Mitsubishi service dept. Followed in his footsteps and spent 17 years in the biz myself and I guess the fact we probably did seven 4 cylinders and two V6 motors to each V8 and very few big blocks so our cranks were much lighter.

@@odysseas7705 I think you are slightly confused. They didn't make a 440 hemi, but mopar made a 426 hemi, which this 11,000 horsepower engine is based off. The 440 on the other hand, is a wedge based engine that was more torque related. The pistons and heads are very much different, and the 440 was made to 1978, where the hemi stopped in 1971.

The 440 is in the B and RB (Raised Deck B) family of engines. The hemi is a seperate family. They did make a 426 Hemi and a 426 Wedge but they are not the same engine. Sort of like how a 351 windsor ford is not the same as a 351 Clevland ford.

You could make a 10 part mini-series about a top fuel dragster’s components if you wanted to get really specific and unpack all the details. A serious documentary without any flash, just pure substance and technical details with the occasional anecdote thrown in. A stodgy British man could narrate like they do so well in WWII exposés and other historical programs.

@markD5150 5 лет назад

Nitro is used because it runs cooler has oxygen in it and burns slower relative to the amount injected vs it’s perspective counterpart gasoline. Nitro keeps the engine from pre igniting due to high compression and excessive boost and high charge temps “detonation” is what kills pistons and connecting rods due to the fuel air mixture igniting before piston hits top dead center. Ps By half way down the track the ends of the spark plugs are melted off and the engine is dieseling the rest of the way down the track. the only way to shut it off is to turn off the fuel supply.

@josephschaefer9163 4 года назад

Burned plugs happen like 2 percent of the time. They shut the fuel off so it doesn't hydrolock

@TechnikMeister2 5 лет назад

Engine life is 12 runs at 5 sec per run. Thats only one minute of use. And how much for a rebuild....maybe $60k. Thats $5k per sec it costs to run this motor. Outrageous. We ran speedway bikes on Nitro and methanol. One gal gone in a 4 lap race...One mile. The guy who brews up the fuel mixture had to wear full hazmat gear and poured it into the tank from a class lab beaker. That was cool. The other reason methanol is good is because it runs cooler. The engines we used were 500cc SOHC producing 100hp at 11,000rpm and compression ratio of 14:1 naturally aspirated.

@rjm8111 5 лет назад

Not so accurate!You need to consider the time from when they first start the engine,do the burn-out until they shut it down,it would be more considerably more than 5 seconds.

Alcohol in Nitro NHRA is just so cars run 90%. Basically just takes up space. Rules were 100% till Doug Herberts blew up in Pamona 1999 at the Hit. The Roter from the Blower ended up in the RV Parking lot. Then they went to 85% for that season.2000 season it was and still is 90%. About this time Rev Limiter was required. Currently 7,800 rpm i believe. Activated after 3.0 seconds. About the time of clutch lock up around 660'. That's the time of max power when it's climbing the Torque Curve after Clutch go's 1:1 Crankshaft = Input Shaft.

@slowpoke96Z28 2 года назад

Between turnarounds, there’s warm up, possibly more than one, then start, burnout, back up, staging shenanigans, then the pass.

@manstersr 5 лет назад

That was a great show, the only other things I wish you had shown is how they start the car on gasoline or alcohol (I believe is what they are doing) then switch it over to Nitro. It's so cool to hear the contrast when they flip the switch, it sounds like a regular engine until they switch it then it sounds like it gets really pissed off. The other is how they mount the engine in the frame with a few hose clamps, a friend that built the frames for those cars told me about that and how they don't really worry about clearances and tolerances in the engine too much, like you would a normal race or street engine, because it only has to run less than a minute or so. They basically throw it all together is what he said.

@slammedsilvias6628 5 лет назад

Why do they change the firing order? I know it’s for power gains obviously but I’ve never seen anything explaining why it works and the other benefits. I’ve wondered this for a long time and was hoping I’d see it answered in this video. There’s hardly anything on RU-vid about top fuel engines. I hope you can shed some light on this question for me.
