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

Right off the bat, it lacks any track record that could lead to FAA certification. Then the orientation isn't conducive to fitting in the nacelles of existing aircraft.

Somewhere along the line, I came across a discussion about why most GA engines resemble old Porsche power plants. One thing I learned from that was that flat engines worked for that purpose in part because the plane could have an optimal prop size and height without a gearbox, and the pilot could see the runway ahead. It also talked about how simplicity reduces failure rates; you never want a forced landing in any plane! I'm just repeating what I read years ago.

ROTAX was founded way back in 1920, but it was a major investment by owner Bombardier that got the company into aircraft engines for the first time. And of course there was Porsche's contribution to Continental & Lycoming that pushed that design to the front in the '50s. When I was a kid, we used to fly from Chicago to Amarillo to see relatives. The flight would stop in Wichita, where all these guys with white shirts and skinny ties would pick up their oscilloscopes and IBM disk packs and get off. Back then, Wichita was a hub of GA aircraft design. The industry wanted everyone to own a plane. I wish we could return to that time of great expectations! And yes, having more engine manufacturers investing would be very good indeed.

@@custommotor unfortunately linguistics (saying "modern") doesn't magically invalidate the laws of nature that have always existed. 15 RPM isn't gonna happen with a motor that size. Likewise, you can tune an engine to be strong at a given RPM, but it comes from somewhere. A big turbo will take forever to spool up because of inertia, and a small one will run out of CFM before the head does. The only "modern" addition to that formula is using electric motors to spin up the turbo, making it a hybrid. But then, you might as well use the hybrid system to power the car directly.

If I was an off roader easily put it what ever Jeep or other 4x4 I had . 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!

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.

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.

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.

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. Never had mine on the dyno, but that car (thunderbird) would easily outrun bolt-on LS1 camaros back in the day. Probably 350-400whp @ 25psi boost.

If they make the thing relatively affordable, it'll be a circle track killer. I'll take inexpensive for a CJ-5 project right now.

Big 4 cylinders don’t typically rev high enough to really make horsepower. It’d be good on torque, but so would a smaller engine with a blower. For the cost and hassle might as well just do the V8 swap. Funny thing is the 4cylinder would probably be harder to fit since it’s standing straight up and would be tall.

Na or Nb Miata would be amazing. Even naturally aspirated.

@Cowboy.underwater Ай бұрын

If that’s the same rectangle port head found on the ls3 and ly6, that motor should easily make 300hp NA at pretty reasonable RPM.

@Cowboy.underwater Ай бұрын

The size could definitely cause some NVH issues though at higher RPM, so maybe 250HP NA is a better estimate, just because it might shake itself apart if you spin it high enough to make 300.

A 3.6L inline four will shake itself to pieces at 5000rpm, even with a balance shaft. No way is it going to turn high enough to hit 300hp more than a few times.

If you have the 2.2 get rid of it and purchase a remanufactured 4.3 for half the price. My stock 4.3 has 440k miles and still running great. I will absolutely rebuild it and keep driving it on to a million miles.

If there were a NA version and the output was suffecient, I'd build a generator in the 40KW range with the low RPM for many hours capability it should have and run it on propane at my farm. Yeah, I know not flashy, but I don't have a smaller truck than a 1 ton. I would assume there are great automotive applications for the turbo version.

An '09 GMC Sierra 2500 wide-side (parts truck). And I'd take the L96 out of that to build for another project. And, the L96 in it now is getting tired. So I'd love to put a small turbo on one of these giant 4 bangers and get some killer gas mileage.
