Blue Print Engines gives UPDATE on LS 4 Cylinder

[@kevinmartin1679]

My 94 s10 been sitting in the barn since 2023 waiting on this unit

[@Freakashoni]

Me personally I feel this is the engine swap the 2000-2010 impalas Monte Carlo’s and even the Grand Prix needed. a soul American based competitor to the vtec engine along with competition to the civics and such. The impalas from 2000-2005 are suprisingly easy to work on if you have some technical knowledge same with Monte Carlo’s Buicks and Grand Prix s from the same year, they are great first cars and basically bullet proof the engines last longer than the chassis though. I feel the impalas and Monte Carlo’s need more love which in the right midn they do. With how widespread the cars are and how cheap they are to get they pretty much are the best first car for less than 5k without major repairs. If this engine ever gets out it’s a complete game changer. A kid with about 10k (I’m only guessing not actually sure) can buy a simple Monte Carlo impala whatever. And literally have it engine swapped and rwd swapped if they want. As I said game changer. I’m going to go military and when I get out of this engine is out I’m swapping my impala with it. I’ll have money to do so..

If the block was Aluminum i could see ppl in the light sport an experimental avation world being highly interested in the turbo version with so much power at low rpm. Kinda depends on what the primary and secondary imbalance vibrations are like tho, from what i understand.

[@twotrackjack2260]

@StringerNews1 I'm just beginning to learn about aviation engines. I don't know anything about the requirements the faa would require, just noticed that in small platforms people seem have been able to use automotive engines and snowmobile engines if they were small and light enough to fit the platform. Obviously I have much more to learn about such things, thanks for the correction.

[@twotrackjack2260]

@StringerNews1 Ahh I got ya. Yea, everything I've learned thus far has hilighted the benefits of using a boxer style engine. However, that doesn't mean they're the only way to go. My only non commercial flight was in a home built kit plane in the late 90's, it was powered by inline 4 cylinder volvo car engine. Can't remember if it was turbo or not, but I was really surprised by the fact he could use an automotive engine.

[@GroovesAndLands]

Liquid cooling is a lot of complexity for very minimal gains in GA aircraft. And drag saved by not needing airflow over the engine proper is extra drag for the scoops/ducts to direct airflow over the radiator. Also, without a reduction gear (PSRU=propeller speed reduction unit), about 2750rpm is maximum permissible RPM for a GA sized propeller plane. PSRUs are heavy and expensive - which is why few GA planes have them. It's also why the GA planes all have the same 360 or 540 cubic inch Lycoming or Continental horizontally opposed engines. Last, you never see high performance turbocharged engines in GA planes. You might see them in experimental planes that don't need to meet the rigorous durability standards set by FAA. You see some turochargers on GA planes - but they're not "high performance" the way automotive hotrodders think of it. Rather, they're usually set up in a "turbo-normalized" configuration - which is to say VERY low boost at low altitude and SOME boost at higher altitudes - essentially achieving equal power regardless of altitude. The cylinder pressure required to make big power at low engine speed is just too risky for GA planes.

[@Adam-nv9zo]

This would be awesome for so many applications.

[@Bozemanjustin]

When I saw this motor for the first time and read the stats. It's an LS motor. 3.6 l. I simply applied the same calculation. I applied to all all motors. I figured out how much air you could move through the thing because that determines the horsepower motors are just air pumps 3.6* 61* 8,000/3456 If you can make a full size LS spin to 8000 RPMs you can definitely make a half size LS do it too At those specifications that I just gave you which is cubic inches* RPMs and then divide by the standard, this motor moves 508 cubic feet of air per minute. A standard hot rod motor has to move about 1.35 CFM to make a horsepower. An IndyCar motor is closer to 1.0 CFM to make a horsepower. If you go to things like the old old 1988 trans Am, it's more like 2.8 CFM to make a horsepower But modern-day hot rod motors, if you sit there and do the math on every Dyno run you see average about 1.35 CFM and then if they have compression Ant a high lift cam you can get it closer to 1.28 So this motor with the proper cam and RPM is perfectly capable of making that 340 horsepower naturally aspirated don't even need the turbo But a good turbo on this thing and it would be a monster Also, I am very well aware that CFM per horsepower is usually not a reference point that people use. It was simply the metric that I started with years ago watching dynamometer runs and calculating out how much air they were moving to acquire that power

[@rootbeer666]

Not sure about the 8k RPM because it's a very long stroke from what I understand. From what I understand it's based on an engine used in airport tugs and stuff like that. I'm very interested in what they will come up with.

[@PistonAvatarGuy]

Balance issues would prevent the engine from ever reaching anything close to 8k rpm. There's a reason why 4 cylinder engines rarely exceed 2 liters of displacement by any significant amount.

[@bryanst.martin7134]

Torque per liter is my question. 500 lb/ft at 1800 rpm?

[@383mazda]

This motor won't get near 8,000rpm. It'd be surprised if it revved over 5500. 4 cylinder is a totally different engine than a V8. This is an industrial motor (for generators and heavy equipment), the muscle car world just went nuts because of the LS head on it.

Relatively light, twist like a big block even at 10,000 feet, 1/2 the fuel or better, simple to work on… plenty of room to fit it in. Yeah would probably like it at a less shaky 2.5 liters and settle for 350 ft lbs of torque and 225 HP but a 5k redline. I think there’s plenty of potential even in 2.5 l. Doesn’t the new Acadia run pretty close to that displacement and the 4 cyl Bronco is like a 2.3.. I think both of those with turbos are around 275 300 hp and again if you look at engines from the 80’s 1 ton trucks were running big blocks with similar numbers and pulling 10k lbs trailers so plenty of juice for a 4x4 😀. A 2.5 with a 6500 redline might be an awesome rally or autocross engine especially in an aluminum block!

It's an interesting idea, especially for the S10 swappers, but... to be honest though, if I could stroke my 2.2 to 2.5 and do some other basic massaging and get 150hp and decent torque NA, that would be on the books first. That little thing's been giving me 120hp (or less) for the last 340,000 miles and is rarely less than "adequate", and that's all I want. Then again I'm weird enough to occasionally think about a 3 liter (circle track) Iron Duke in a 30's roadster or a model T runabout with a G10 in it. Yes, that G10, the Geo Metro (suzuki) 1.0 3 cylinder.

[@vinniegillotti9347]

Blueprint I hope you read the comments if I remember correctly, it had an LS3 style head, but I also thought you had a hemi head version which would be fantastic because of the flow dynamics of the head. I think it would be fantastic for many reasons, jeeps rat, rods, little hot rods even full size trucks open your forethink for a turbo, charging pro, charging fuel injection and carbureted. I understand this is a back burner thing for you, but honestly, the possibilities could be endless because the Cummins 4BT Has gotten very pricey

[@GroovesAndLands]

You're overthinking the cylinder head - because inline fours have god-awful balance. You can get away with it on little L4s, but the bigger they get - the worse the balance gets. About 2.0L is on the edge without balance shaft. 2.5-3.0L is on the edge WITH balance shaft. This is why you don't see big L4s that do high RPM....as in above 4500-5000 or so. Even the 3.0L Porsche 924 engine shook like a dog pooping razor blades at 6000. Coming back to the point - if you're not gonna turn high RPM, you don't need big heads that flow great. All you can really make use of is a good, moderate head - like an LS1 or LS6 type, so long as we're talking about LS's.

[@hendo337]

They should make a cross-plane crank so that it will have a V8 like sound and it may be better balanced than huge I4s without a balance shaft are. If they could go 4.125"x4.125" or 4.125"x4.25" or 4.185"x 4.125" or 4.185" x 4.25" that would be really exciting as an N/A engine 350hp or more with one of those Blue Print rec port LS heads shouldn't be a problem at all, Richard Holdner got 700hp from a 468ci stroker with a factory 823 head.

By the way, Smokey took a stock Iron Duke, put a small supercharger on it with a turbo, stock fuel system with a bit more pressure and the stock HEI ignition system with a bit of tweak and made 250 hp with over 350 ft pounds of torque and not a single peep of ping or knock. That was on a used, over 75k mile, Iron Duke with the stock head. Guess someone had to finally figure out how to get a better Iron Duke and they just might have done so. Kudos! Now get it out as a kit or assy and let's get on the road with it.

[@GroovesAndLands]

If it's one thing I learned from my days playing with Ford 2.3L Limas...It doesn't matter how bad the cylinder head is, so long as the bottom end is strong enough to handle boost.

[@ChrisScratch]

Hopefully after all the r&d costs it's still remains cheaper than their V8 options or else it seems kind of irrelevant. A compact naturally aspirated version is the only thing that makes sense to me since if you're looking for additional power and needing extra space for a turbo and intercooler, you may as well just get one of their V8 options that already exist. At the end of the day, if it's actually based on an LS4, all I really want is that custom engine block and crankshaft (and maybe oil pan) then I can just put off the shelf LS4 parts in it (conrods, pistons, cylinder head, cam, etc) and build it out however I want.

Honestly, I think there’s even a market for the guy that just wants an old car that’s a cruiser. Wants to be able to take their vintage car or truck out reliably, and not burn a lot of money on fuel if they don’t want to. There’s a ton of options out there for big power. There’s nothing with this concept in mind, unless you’re talking an old straight six and they’re getting harder to find parts for let lone find at all anymore.

Will it fit in a Miata?

[@kens8903]

This in a Miata or Lotus Elise would be amazing. An S-10 would be great too. Could have one swap for work and the other for fun.

I venture to guess that the real issue is in its high cost for it's relatively low horsepower numbers. I personally have not seen any anticipated cost numbers, but its unlikely to be under 5k.

[@robertg.tibelljohansson7869]

would be nice to look at as a comparison on the old redblocks on old volvos 🤔

[@souralba2727]

Having did a bit of digging, the 340hp-500lbft figures are with boost at 1800 rpm. Under design by blueprint engines using an origin block.

[@automotiveantics]

That is correct

[@spiketheimpaler4698]

Are they the same company that was building a 4cly hemi

[@MikeSmitty-j8t]

Pretty sure they claimed those numbers naturally aspirated. I even have a pic of the placard from pri where it said 380hp natural aspirated

[@mrjim1973]

Yes please!!!

[@DarthDarklorD]

love to see this in a boat

[@lucasblanchard47]

I’d be tempted to put one of those in my 1969 Chevelle Malibu Sedan. But I’ll probably rebuild the stock 307 V8 first.

[@jalanlee32]

They need to make the bolt pattern fit most ls trans

[@automotiveantics]

Sounds like they did
