Two Small Block Chevys On Nitro And Eyeball Aero: The Story Of The Pulsator Top Fuel Dragster

If there is one year in drag racing history when the sport went totally haywire, 1965 is it. It was the time when funny cars changed by the week, the 426 Hemi first showed up in a top fuel dragster, and everyone and their brother was experimenting with aerodynamics.
In this video we look at one of the most unique top fuel dragsters of all time, Nye Frank's Pulsator. This car used two nitromethane burning, injected small block Chevy engines, a custom built chassis, and a handmade "aerodynamic" shell to take on all comers.
The story is one of an amazing era where experimentation was the way of the world at the drags. Nye Frank was a fascinating and brilliant guy who could make anything and did over the span of his life.
The Pulsator and other aerodynamic experiments are explored here as well as the Pulsator II that was the follow up act. This is one for the ages!

[@BobDavids-en8mc]

Bobby Davids here. Nye & I built the body in his PlayaDelRey home garage, we used urethane foam to shape the body on the chassis. Nye built a ‘spit’ so I could shape the underside. I was a car design student at the famous Art Center College of Design; we built the body in 90 days starting June 1964. We both worked on both Spirit of America cars. Surprised to see my pic with Nye in this video. The history is accurate…Bobby

[@UncleTonysGarage]

The missing ingredient to all of the early streamline and twin engine nitro efforts of the day, was a lack of understanding of the effects of load. Liners went quicker without their bodywork because the engines were more effectively loaded when they had to push through the wind. Nancy's liner worked because it was a gasser. The same thing applied to twin engine cars. During the run, the combination of engines would drop cylinders until their output matched load. The thing that made this exceeding difficult to tune around, is that the engines themselves would decide which cylinders were going to be used and which ones were going to float on any given run...at any given spot during the run. Jr. Brogden went through the same issues during the same era. Adams and Enriquez tried the unblown twin fueler concept again around 1970 with the Double Eagle car, and had identical problems. They played with engine phasing to overcome it, but the knowledge of tuning for load just wasn't there yet, and didn't really become accepted science until around 1973. The failure of the Jocko/Garlits liner can also be directly attributed to this. Funnycars worked at that wheelbase and weight, but they worked because they fought the wind, which kept the engines loaded. The liner was too slippery for its own good. Had they run mostly alcohol through it, the concept may have actually worked. Somebody...and I think it was Ed Pink figured this out at around this same time, and started overdriving the pumps on their Funny Car combinations to take advantage of the bad aero, and at that point F/C's started to match the mph of the diggers, and suddenly the answers were apparent, but still not completely understood. The next phase didn't begin until Dale Armstrong, in an effort to "calm down" the ride to suit Kenny Bernstein's driving, started running fat and taking away gear, and inadvertently went faster. This led to the double pumps, double (and even triple) mags and lock up clutches that brought everything into the modern era. Ha! Sorry if I wrote a book here, but I spent a bunch of years with my head buried in this shit. Great video as always, Brian.

[@joshuagibson2520]

Damn Tony. Talk about some of this type stuff on your channel. Would make for a great weekly segment.

[@76629online]

I was fascinated by the part where he talked about how the two engines made half power when mated together. I read your post several times to tried and catch on to what you were saying, Tony. I'm not following it just yet. I agree that load plays a role in this scenario, but there's some odd physics at play when you couple two independent engines together with a rigid coupling like that. They work against each other. The proper way to couple them is through a gearbox that provides each engine with its own torque converter. Much in the same way that a multi-engine helicopter drive works.

[@jamespurvis8880]

My thinking was if they had treated the firing order as a 16 cyl engine the front engine would not unload the aft engine. kind of like a radial engine with banks. just a theory. Impulse phasing.

In the late 1950s, there was a unique shaped car. It was built by the Cortopassi brothers in Sacramento CA. It was called the Glass Slipper, a fiberglass bodied slingshot style car. They ran it in the drag races and at Bonneville. I think it may have been the first streamlined fully enclosed dragster and definitely one of the first fiberglass bodies. It was awesome to see run. I think it was built in 1957.

[@brianlohnes3079]

The Glass Slipper is 100% a foundational piece of drag racing history. Great pull on this one.

[@brianlohnes3079]

Wild, right?

[@andyharman3022]

Lack of torsional damping in the system probably caused wild spark scatter in the rear engine. If the bearings were being pounded out of the rear engine, that points to spark timing that was very, very advanced.

Brian , there is a very provocative history concerning Don Garlits full bodied dragster . The body was designed and built by a major gearhead and artist by the he name of Jock Johnson. I spent a month or so with the man who was hired by my neighbor Harley Klentz who was building a Baja 1000 Ford f150 for the owner of a Ford dealership. Jocko was a very unique individual who could build anything, His body design is still on display and was sponsored by Wally Moon I believe ( there are two) was tested by Garlits and found to be unstable at top end, try his developed heated disagreement between the two men that was never resolved I guess. I look up to both those guys and Harley Klentz as innovators who excelled at thinking outside the box

[@brianlohnes3079]

Jocko is one of drag racing’s great eccentric geniuses. His rejection letter back to the hall of fame is legendary.

[@stevenborham1584]

UncleTonysGarage"s comment is really interesting and some responses to his comment feed into the coupled engine mystery. I have only seen twin engine stuff work when they each have an axle to drive as is the case in modern piston powered land speed racers. But tuning them is fun I bet. BRM (and others in 50's F-1) made V-16 engines with their output taken mid crank/block to a side-winder type gearbox (later motorbike designers inspired by this I guess). I often wonder how tractor pulling teams tune 5 engines chain driving one output shaft. If the twin engined streamliners ran as true v-16's then they most likely would have broken crankshafts (they already would have figured this) from torsional vibrations from 16 power events ringing through each crank (this probably also would have exploded the chain coupler). My 2 cents is that they needed the engines to to have mirrored firing patterns (from mid point of both assembled engines) and a torsion shaft chained/geared directly on front and back of both cranks (to cop all the torsional abuse, perhaps designed into a machined billet deeper sump). Running both engines off one blower is a good idea but look at what RR, Allison, Daimler Benz etc in aero engine development did to properly tune their induction systems on only 12 cylinders in one block. As a rule coupled engines have only ever worked with fuel and ignition driven from one point for each respective device/system for all, not twinned (excluding magneto redundency of twinning them). Coupled aero piston engines without exception either drove co-axial contra rotating seperate propellers, or had very cumbersome and heavy coupling/decoupling capable gearboxes to drive a single propeller. And of those I have seen that only Allisons V-3420 worked with any acceptable reliability in the YB-29 (probably why Allison later made really good heavy vehicle gearboxes). Napier also did well with stacked 12 cylinder boxer engines to make the Sabre engine. It had paired firing events but they fired mirrored in both axis eg FTR+FBL...then 4th row TR+BL etc so no excessive torsional build up occured where they geared together in the nose case. Their later Nomad engine took engine balance, torsional dampening, and coupled power recovery turbines to the limit, and probably still bests most modern equivalent gas turbines for thermal efficiency at that power. But yes they were much heavier.

The power loss & engine damage with the twin engines was a phasing issue. We solved it years later with the 4 engine Herbert car.

[@dukecraig2402]

What was going on with all that? Why'd it work on gas but with nitro the rear engine seemed like it was dead and being driven by the front engine resulting in it being shredded? It wasn't apparently since it did add 50 HP but from the results you'd think that the power from the front engine was going through the rear one that was just along for the ride. What was going in with all that?

[@nzsaltflatsracer8054]

@@dukecraig2402 The simple explanation is power pulses acting against each other are absorbed by the less dominant engine. That results in less HP coming out the end of that combo & that engine suffering internal damage. The best survival time we had was with splined crank connections & one ignition system for two engines but that wasn't feasible with 4 engines in a row with two turned around backwards to counteract chassis torque.
