What an amazing restoration and display! More than 70 years after it was first introduced, this type of engine will go on and on in history and in the hearts and minds of those who have ever worked on them, used them, or produced them. Thanks for sharing this all with each of us!
October 5, 2013 - Lake Chelan, WA. The engine finally made it into the boat and it ran great. We put about 1-1/2 hours on it and the only thing that was going on was a slight oil seepage out of the crankcase vent fitting. Ran up to 2800 RPM (approx 120 MPH) and was very responsive. Can't wait for next year and run it a whole season.
a beautifully prepared and presented vintage engine. very easy to see the care and craftsmanship this engine has had lavished on it! the sound is just the cherry on the sundae!!
jeepsasurusrex I too enjoyed as a teenager watching these "Thunder boats" run on Lake Washington. Also had the opportunity to see the Original Miss Thriftway when it was parked at the local Thriftway store. They even allowed us to climb in and around it . Very impressive.
This is probably my most favorite engine of all time. My dad used to maintain and repair these on P-38’s It got a bad rap because the Army Air Corps set a requirement for an engine just like the V-1710. They didn’t ask for turbocharging. With turbos the aircraft with V-1710 engines responded at altitude at least as well as the Merlin. Thanks for posting this video. Brings back memories of talking to Dad about his time in the South Pacific.
Great sounding engines. As a kid living in Seattle in the 50s and 60s there were several unlimited hydro races each year. There is nothing like having a 10-boat flying start with all at full throttle. You could hear them 10-15 miles away. The current turbine powered boats today have nothing on the old boats.
As soon as I saw the first turbine boat in San Diego, I knew it was over for the Rolls and Allison powered beasts. yeah, the new boats are faster, and sleaker, but there's nothing like feeling in your chest and gut when 6 huge v12s come full throttle down the start. And the smell....i'll never forget that!
this is the best engine ever made....................and they sound so damn good..............these where in most Truck Pull Trucks back in the Good Ole Days
One of the best Allison's I've heard in a long time. My hat is off to you fellas. Still prefer the Rolls Merlin, no disrespect. This sweetheart purrs like a baby kitty cat. Thank you for keeping these incredible engines alive and running. Sounds strong, real strong. Running nitrous? Most of them make it about fifteen minutes on nitrous. I am sure you know this and you don't need to hear it from an old fan like me. Anyhoo, how I miss the UNLIMITED HYDROPLANES with this sound. I swear that sport would climb out of it's hole if they made those boats sound like this again! Thank you for sharing your hard work with us all!. C. Jerald-Washington State
FYI - we have run exhibitions at the Tri Cities race seven out of the past 8 years. There is a good possibility we will be there again this year (2014) along with two other vintage unlimited (1962 Miss Bardahl and 1957 Miss Wahoo)
Today, because we run exhibition and are not racing, max RPM is around 3500. Back in the day when they were racing, it was not unusual to have a driver see up to 4200. In the airplanes, the max stated in the manuals is 2800.
Some of the early (1950's-60's) oilfield frac pump equipment were powered by surplus Allison engines. The camps that used them had fuel tanks for aviation gas. I was told by an oldtimer that you didn't count how many Allisons you had - you measured how many acres of Allisons you had. Never got to see or hear them as a young engineer in the late 1970's because by then they had been replaced by diesels and gas turbines.
dan at canyon lake I have heard that too , E.J.Potter , the tractor puller started with over 100 of them , and said when he ran out of them he would retire.
Hey rim975, if you don't like it, go out and buy one for yourself and do with it you deem appropriate. There's no need to slam what we're doing because we have working engines put in an application in which it was actually used. At lease WE are doing something!
More than one person has been confused thinking that this is a V-24. The confusion stems from the fact there are 24 exhaust ports. The Allison V-1710 is a 60 degree V-12 design. Here is a link to a photo that shows a bank without the exhaust manifold and not installed in a crankcase so you can see the six cylinder walls: www.missthriftway.com/images/11-14_01.jpg
There was a Ted Danson movie with a vintage hydroplane boat race, with these engines. I watched some takes filmed. There's no mistaking the exhaust signature. ,
It was back in 1970 at a car show at West Port Plaza outside Mall when I spotted a trike with one of these engines. It was freaking amazing. Yes it was powered by an Allison V-12. Haven't seen it since. My friend took a picture of it but he's passed on now,R.I.P. If any one knows of this trike ,please post it. It is really something.
The wiring on this engine has just been completed and we will be prepping the boat to put it in and test fire it very soon. Stay tuned and we will post it firing off in the Miss Thriftway.
I recall these engines were mounted 2-per frame for tractor-pulling. (1980s) Even ONE of these bad-boys was louder than 5 V8s mounted on the same tractor. (and could out-pull the 5-V8s too) Nowadays, you do not see these engines at tractor-pulling. I think parts-supplies for the Allison became too hard to find.
Nothing like the sound of one of these in an open class hydro... Polson Regatta... Montana... late 1950's... getting old here... Speaking of old, I didn't see anyone in your video that appeared to be under 50...
Just out of curiosity because I LOVE WW2 era piston powered aircraft - what is the value of an Allison Engine like that today? I know they're somewhat rare and the air and boat racer people are always looking for them.
+Rene Andre The price depends on the condition and serviceability. If the seller has complete documentation to flight-certify the engine then the asking price will be very high. A rare NOS engine in the crate with full documentation will sell for VERY high. A worn-out engine will sell for less. Engines wrecked by the boat racers will sell for less, although new techniques from the engine restoration shops are making it possible to revive a few boat engines or parts to fly again. The tractor pullers have been wrecking whatever is left that they have been able to get their hands on.
Yes it was. It was also the first engine in the P-51 but for only a short time. The Rolls Merlin performed better at the higher altitudes and became the engine of choice for the Mustang.
compton98074 The Rolls powered P-51 could only fly inverted for 10 seconds because it was a wet oil sump oil pump. One of the two engines also could not fly inverted long because of the float bowl on the carb.
@@compton98074 Only the LATER 60series Merlins had the 2 stage supercharger, ALL Merlins were NOT created equal, 2/3 rds of all merlins used in WWII were just a single speed supercharger !!!
kleetus92 Sodium-cooled valves were the breakthrough for this technology. If not for the valve technology you would be hard pressed to put a 1hp/lb engine in the air. Pushing great volumes of air required big openings that could be sealed with a thin removable cover. The waste heat in the exhaust also produced high temperatures. It was a tough nut to crack with the materials available at the time. A British gentleman (Harry Ricardo) experimented with sleeve-valves to deal with these issues too. Those worked as well as sodium-cooled types and made it into many WW2 designs. But poppet valves eventually won out as the preferred technology.

Awesome! Two questions: 1) What are those two tanks that look like beer kegs for? 2) What is that braided hose that is going out several feet from the engine and is just spewing out something onto the ground? At first I thought exhaust but the exhaust should just be out of the sides of the engine, right?
Gorgeous engine. Quick stupid question, is there 100LL avgas in the kegs? I see many engines running on stands that are fueled by containers like that, and I can't seem to figure out if they're pressurized, gravity fed, etc.? I feel kind of dumb, I'm pretty mechanically inclined but I can't seem to find any info on them. I also see many large diesel engines being fueled by such containers. Can't figure it out.
I hope a late reply is better than no reply ;) We use both the fuel pump on the engine and an additional boost pump to help in starting. We run a fuel pressure level around 21psi via these pumps, but the tanks themselves are not pressurized. We have two fuel cells for a total of 75 gallons when full. Both tanks have shutoff valves and we typically run on only one tank at a time.
nice- my pops restores old motors. he just got done with a 2500 ci packard... back from the glory days of WWII. he also rebuilt a Curtiss(1914) I believe, only two in existence...they lost the contract- way back when.--- and I thought Aviation Fuel was 99 octane... You say "one hundredLL" is that a better quality fuel?
Peter43john NO !!!! ONLY the LATER get that LATER 60 series Merlins that got the LATER 2 stage supercharger performed better and only above 20,000 ft Allison had a single stage supercharger tuned to work best 20,000 ft and down,
If my memory is correct, this type of engine was first installed in the P51 mustang flown in WW2 before is was replaced with the Rose Royce engine because of it higher hp. Nice video.👍
kingpin You mean a Rolls Royce ??? But a RR Built merlin was NEVER used in a Production Merlin Mustang as none were available anywhere let alone the USA why RR Had contracted with PACKARD in the USA to build the Merlin..FOR THE BRITS and because the Merlin was available in the USA Thanks To PACKARD it was available for use in the Mustang !!! BUT ALL Merlins used in all Merlin Mustangs were Made in America by Packard !!! and FYI ONLY the LATER get thatb LATER versions of the merlin the 60 series had the 2 stage superchatger that gave it more power ONLY above 20,000 ft !!! The facts of history less the lies hype and Bull$hit !!!
It is interesting that this can be started so easy. All I see are old worn out engines at the Rooster Tail in Detroit. Bad batteries, cold oil, bad spark and blow by go write home about seem to show up in Detroit.
+Mike Smith Yes we could, but our intent was to replicate the original raceboat as it ran back between 1955-57. The Miss Thriftway started with, and ran, an Allison from 1955 through 1956. In 1957 it was fitted with a Rolls Merlin and ran the Merlin until it's demise on Sept 29, 1957 in Madison, Indiana
Sarcasm is hard to detect through the internet, so I'm not sure if you're serious or not...but this engine was of course used to power many aircraft - perhaps most famously, the P-38 Lightning, P-40 Warhawk, and P-51 Mustang, among about 10 other aircraft and a tank (T29).
How far away are your nearest neighbours? If you didn't warn them, they'd be saying "WHAT THE @#&* WAS THAT?!" If it were me, I wouldn't mind, so long as you didn't do it at an unsociable hour lol. Good work on resurrecting a piece of history
Probably my all time favorite engine. Fell in love as a little kid seeing them at tractor pulls, that unique sound gets me every time.

a v12 has to be the sweetest sounding engine of them all
Especially the Allison...

someone has done a great job working on this engine, smooth as glass!!! bf
The Packard 12 was also a first class engine. Lots of fame and glory powering the PT boats x3.
***** yes I need to do some reading on the Genesis that motor
At least we've got one! (To really piss you off, we actually have TWO!!!!)
I'd sit there and listen to that every morning with a cup of coffee.
There are two exhaust ports per cylinder
4 valve per cylinder then?
@@willybones3890 Well DUUUUUUHHHHHHH !!!!! And the overhead cams had roller rockers on them something the Merlin did NOT have !!!!
I remember when the Columbia River roared with these babies! Those were the days! :D
as do I :) Tri-Cities Water Follies, and so on...
Fatboy Dan
Yep! Wasn't it freaking bitchin'! ;)

That's neat! Hope to see you there. I have friends that volunteer for the Water Follies.
The Allison was a anchor in that particular aircraft, Now in the P-38 with the turbo-superchargers it was a monster!
vector the Allison was never an anchor as the Allison Mustang was faster than a mrlin mustang or the $hitfire under 20,000 ft. DUUUUHHH!!!!!
NICE running engine!!!

gregg that engine would not even fit in the bed of your "pickup Truck" !! !
Just awesome.
Beautiful beautiful noise..
Fifty years ago,one of my Uncles was mechanic on speed boat (open class hydroplane) with one of these . Nothing thrifty in the way it drank fuel.
Love these old girls. Luck to ya from Lake Coeur d Alene
very cool

One keg is for fuel, the other for oil (dry sump). The hose is the water out
Four valves per cylinder, two exhaust ports per cylinder. Exhaust headers can either be two per cylinder or one per cylinder.
Yeah the cylinders are as big as coffee cans so there's plenty of room for Zumiez

Fantastic!
Did they run Dry Sump lubrication in the WW II aircraft? sdh in P&WA country
36 valve overhead cam engine? 2 exhaust per cylinder, one big intake, or is it 48 valve? Sounds awesome!
see: www.missthriftway.com/Photos/engine/Bank_done3.jpg
48 valves

That's pretty amazing for the day.
kleetus92 Sodium-cooled valves were the breakthrough for this technology. If not for the valve technology you would be hard pressed to put a 1hp/lb engine in the air. Pushing great volumes of air required big openings that could be sealed with a thin removable cover. The waste heat in the exhaust also produced high temperatures. It was a tough nut to crack with the materials available at the time.
A British gentleman (Harry Ricardo) experimented with sleeve-valves to deal with these issues too. Those worked as well as sodium-cooled types and made it into many WW2 designs. But poppet valves eventually won out as the preferred technology.
Yup, they did some impressive work with just the slide-rule.
48 valves 4 valves per cylinder and overhead cam
kleetus 12 times 4 is 48 DUUUUUHHHH!!!!!!
Vsshooter1,
You and rlm975 do not have the right idea. Miss Thriftway U-60, too, is a historic artifact.
This is not a "race" boat; it is a restored boat that was raced a long time ago. If you read compton98074's reply to Alexi Laiho's question above, you will learn that the Miss Thriftway team limit the rpm to preserve the engine: "Today, because we run exhibition and are not racing, max RPM is around 3500...."
Greg
Did those ever get used in on road big rigs?
The entire process was done by the Thriftway crew under the guidance of Peter Orton at our shop on Vashon Island, WA. - not the Museum
Awesome! Two questions: 1) What are those two tanks that look like beer kegs for? 2) What is that braided hose that is going out several feet from the engine and is just spewing out something onto the ground? At first I thought exhaust but the exhaust should just be out of the sides of the engine, right?
Put that in a nice mid sixty Chris Craft yacht or something?
Gorgeous engine. Quick stupid question, is there 100LL avgas in the kegs? I see many engines running on stands that are fueled by containers like that, and I can't seem to figure out if they're pressurized, gravity fed, etc.? I feel kind of dumb, I'm pretty mechanically inclined but I can't seem to find any info on them. I also see many large diesel engines being fueled by such containers. Can't figure it out.
I hope a late reply is better than no reply ;)
We use both the fuel pump on the engine and an additional boost pump to help in starting. We run a fuel pressure level around 21psi via these pumps, but the tanks themselves are not pressurized. We have two fuel cells for a total of 75 gallons when full. Both tanks have shutoff valves and we typically run on only one tank at a time.
compton98074 That makes sense! Thanks for the reply!

You say "one hundredLL" is that a better quality fuel?
This Type Engine Was in P-40 TOMHAWKS and A-36 Aircraft!!!
Beautiful...
Say, what is the CID? Is there an advertised torque rating for this engine you know of?
thanks for nice work
joey
Yeah LOTS !!!!!
2 exhaust ports per cylinder?
We needed a drive gear for the gearbox and didn't get it in time to run the engine this year...2013 for sure tho!
do these engines require more O2 than the Merlin? Is that why they could not perform as well at higher altitudes??
Peter43john NO !!!! ONLY the LATER get that LATER 60 series Merlins that got the LATER 2 stage supercharger performed better and only above 20,000 ft Allison had a single stage supercharger tuned to work best 20,000 ft and down,

that one little battery is enough to start that monster?

Was this the engine that was removed to make way for the Spitfire engine to make the P51 Mustang work ?
peterglenn NO $hitfire engine was ever used in a production Merlin mustang, ALL were Built and modified by PACKARD in the USA !!!!

Marine application?...exhausts are opposite what would be in a p40, p38 and a36
what fuel you running, av gas?
Which is awesome.
sounds awesome
If this is a v-12 why are there 24 exhaust pipes? I am not a mechanic just confused.
steveprice confused and dumb also. 4 valves per cylinder each exhaust valve has its own port V12 DUUUUUHHHH!!!!!!
@@wilburfinnigan2142 steveprice was anything but dumb. He was a great man.
Hmm... sounds like an airplane for some reason.
Sarcasm is hard to detect through the internet, so I'm not sure if you're serious or not...but this engine was of course used to power many aircraft - perhaps most famously, the P-38 Lightning, P-40 Warhawk, and P-51 Mustang, among about 10 other aircraft and a tank (T29).
Thats because it is an aircraft engine. Only in this case it will be fitted into a boat.
As much as I hate the thought of such a fine aircraft engine going into a boat, I'd rather see it enjoyed than collecting dust or rotting away!
This engine was made for air, land & sea vehicles where real HP was needed.
What fuel are you running it on?
Aviation fuel 100LL
Got to figure out how to fit that in my Ninja.
It won't improve the power to weigh ratio which, other than leaning the right way around corners, is what bikes are all about!!
