[@matthewstorm5188]

“ When equipped with an appropriate turbocharger.” Good point. You’re not getting 500ft-lb torque from 3.6 liters naturally aspirated. That’s more torque than a stock LS7 (which has almost twice the displacement).

It’s NOT going to be priced well. Anything as custom as this is going to cost LOTS - certainly a whole lot more than your basic LS3 crate motor (which, by the way, will make more power). If anything, price will kill this idea. Or, at the very least, restrict its use to applications where there is no alternative.

I love this, and what else that’s interesting, is the 2.7 L turbo four-cylinder that GM is currently using it already at over 300 hp and 430 pounds of torque. Wouldn’t be hard to get to this number with that 2.7 L. Anyways, good stuff.

[@JR-cf3tt]

I can't say that I'm impressed by this. The screen grab @1:29 says that this engine can produce 340HP/500 lb-ft "when equipped with an appropriate turbocharger". So with a turbocharger it produces less than 100HP per liter of displacement. Pretty much every 4 valve four cylinder engine these days will exceed 100HP per liter in N/A form. Plus those two bolt main caps probably won't stand up to a lot of power if someone tries to really put some boost to that engine.

[@mr.2cents.846]

Sounds like fun.

[@Forbiddina]

Yep, reading the specs 340hp/500ftlbs, already can tell you that this engine isn’t revving to 5000. Maybe not even 4000. If it were N/A I would imagine it making maybe 130-150 horses. But honestly being a motorhead, I and most others like me always want to look at things from the Motorsport performance stand point. I think this engine really is more about its intended niche, pickups, hauling and generators. And in those roles it genuinely looks fantastic Since torque is what snaps transmissions, why (other than cool/meme factor) would I want this in my NA Miata over a K20/4 which can safely bolt onto my factory driveline. If I’m swapping the the whole driveline anyway, I’m just going to put a 5.7 in it for the instant N/A torque.

[@beobe99]

Glad someone noticed this... The host clearly wanted to make it seem like this engine makes 340HP all on its own as he skipped the "with appropriate turbocharger" part... So much so, he, later on, mentioned "it can also be turbocharged in performance applications" - NOT that it needs turbo to achieve the numbers he boasted about the entire video.

[@Chazd1949]

The low-end torque version really interests me. I am currently planning to build a 350 with tuned-port injection for my Chevy Suburban and couple it with a Magnum six-speed manual trans. My goal with the build is to maximize torque below 2,500 RPM for towing and fuel economy. A flat torque curve from about 320 ft.lb @ 1200 RPM to a peak of 400 at 2,500 RPM would be great. More torque if possible without increasing displacement or the same torque with a smaller displacement engine that would be better yet.

[@adamconnell5965]

Don't waste your time or money with the SBC... had a buddy for years who was the same way, with small block Pontiacs. 5.3/4.8 is now plug and play in almost everything. My 09 F150 has a 3v 4.6 (weird 2 year only iron block "mustang" engine) and even at 5600lbs and tall gearing it's small displacement plenty for anything other than an enclosed car trailer... open trailers aren't even noticeable. been a blown alcohol and turbo 6 guy for 20 years, so it's not like I use the term "enough" and horsepower in the same sentence very often. The jump in reliability and performance between SBC to LS is exactly the same as from Flathead to SBC. Don't even have to go efi to get the major benefits.

[@briand2614]

Once you get above 2.0L vibration becomes a big problem and balance shafts are required. In industrial or marine applications the engine usually spends a lot of time at midrange RPM and isn’t required to respond quickly to large changes in RPM. They can get away with big heavy crankshafts and flywheels to offset vibrations. Not sure about a 3.6L 4 Engine for performance street applications without balance shafts. It will be murder on engine mounts and flywheel fasteners.

[@crazylarryjr]

I'm sure ATI or Fluidamper have solutions to handle the vibrations. While balance shafts are a chealer solution for Hiop apps they are unreliable due to specific RPM needed to operate properly, If Fluidampr designs can truly adapt and operate in the conditions that a large 4 banger would be subject to, it could be possible to make it work without a balance shaft

[@jeffgriffith7003]

@@crazylarryjr crankshaft dampers do absolutely nothing for the vibrations you would feel from a 4 cylinder engine. What they do is dampen crankshaft harmonics, not primary or secondary imbalances. When you’re sitting in a car that’s running, you are not going to feel crankshaft harmonics, you are feeling primary and secondary imbalances in the engine. Balance shafts are what reduce the primary and secondary imbalances, not crankshaft harmonic vibrations, which is the job of the crankshaft damper.

If NVH's are resolved, this would be perfect for the older Datsun and Toyota minis with a narrowed Ford 8.8 rear, big brake and calipers and the world class 5 spd, or an 8hp transmission with paddle shifters; ooh the possibilities(?). Edit: A front or rear Sump option needs to be offered as well.

This would be great in a lancia stratos or other street / race / kit car like factory fives , race car industries, hawk, lister bell, etc. Well you could also put a Ben Alameda Racing Semi Hemi windsor LS 4 valve head on it. The reason Big 4 cylinder engines do not dominate at this time is because of secondary engine imbalance. This limits the rpm, and size of 4 cylinders to the largest being 2.5 liters roughly with current design usage and technologies. However as mentioned a year before below by yours truly, progressions into the realm of larger high rpm light weight 4 cylinders is on the horizon.

@@ostrich67 Actually both handle very good, even in the snow. The weight difference isn't much....a v6 with a/c...power brakes, power steering, upscale trim package....the most common combination is within 79lbs + - of a V8 with ac, manual brakes, manual steering am radio and basic trim package and hatchback like my 79.

This is based on the Iron Duke engine, the 2.5L 4 cylinder used in a lot of GM's offerings in the 1980's. Pontiac built a special super duty version of it that was 3.0L and had a 16 valve head on it if I am not mistaken. Car Craft did a big write up on it back in the day. They were popular swaps for Fieros at the time. TONS of them were installed in S10's and you could even get one in an early 3rd gen Camaro or firebird. I had an '83 Camaro with one in it, had a T5 and a 3.73 gear, stock. Had plenty of drivable power and it would get 30+mpg regularly.

[@63DW89A]

To keep the crankshaft always turning under a power stroke, a 4 cycle piston engine only needs 4 cylinders. One fact that most gear heads don't remember is that a 4 banger, cubic inch for cubic inch is a torque monster. A single piston is 1/4 of overall displacement, meaning that torque rise is faster than a 6 cylinder or 8 cylinder. So a 3.6L 4 cylinder will make peak HP and Peak torque at lower RPM than a 3.6 L V6 or I-6, or a 3.6L V8. Theoretically with equal volumetric efficiency the I-4, V-6 / I-6 or V-8 will make exactly the same HP and Torque, but the I-4's HP and Torque will be at considerably lower RPM.
