[@Garage4age]

Big thanks to James for running up the Formula Atlantic, on the garage4age dyno! Engine was built to Atlantic spec by Loynings usa. making 254hp on the engine dyno. Chassis is a swift db4 . It still gets out on the track often, which is super cool. Im sure he will jump in here, if I got any of that wrong. his channel: kzbin.info

[@swiftdb4]

Huge credit to you, it's also nice to put an Atlantic on the dyno as a reference point. It confirms that the numbers you are putting out on your home builds are up there with the established big name 4AGE race engine builders.

[@davegt27]

@@swiftdb4 shouldn't that Atlantic engine be reving higher then that

[@swiftdb4]

@@davegt27 The maximum RPM the TRD software for the ECU allows is 10,000. Yes others do go as high as 11500, but engine life becomes non existent and the failures become spectacular. Most that race Atlantic's will shift at 9000-9500 to get ~3000 miles between teardowns (pistons tend to crack). Once you go over 10000 it becomes rebuilds every 600 miles or so.

[@zerohikari2685]

@@swiftdb4 This is not what I was told by Hasselgren. Hasselgren made it clear these engines have a 1000 hour race life. I don't know why someone told you a mileage because no race engines life are based on mileage.

[@swiftdb4]

@@zerohikari2685 no worries, I'm just speaking from my experience. Mileage or hours can be used for service intervals, but it is my experience that what you rev to has a direct relationship on how quickly the engine deteriorates and needs inspection for such things as cracked pistons, warped crank, bearing wear, cam wear etc etc. Just to put some maths to that 1000 hours, when racing the cars average ~105mph. At 1000 hours that would equal 105,000 miles engine life at any RPM (by what you are saying). 105000 miles is about 700 race events or 13 years racing every weekend. I've seen a couple of Hasselgrens fail well before that but that must have just been bad luck ;)

[@sasha-taylor]

honestly your engine looks to have more area under the curve, with just a tiny difference at the top end but a significantly earlier onset in the rev range. Extremely impressive!

[@johnlewis8156]

Agreed! Any 4ag builder that gets close to a formula Atlantic engine is doing impressive work. You probably have another 5 hp in your motor anyways if you wanted it!

[@BMW3.0CS]

Very interesting comparison, the formula engine has very smooth power and torque curves once it gets up there but your engine appears to have much better mid range power. Nice work 😎

[@ToreDL87]

Yeah 4age's are usually like that, build for absolute peak performance and that's what you get, peak performance, at cost of everything else.

[@Garage4age]

This is what i've been trying to show on here for the last 2 years or so. can have an engine that works at both ends of the rpm range if get it right. but most people just look at the peak numbers 🤷‍♂ The Atlantic is specifically tuned for high rpm as. since they would sit in the last 3000rpm there whole life

[@capnthepeafarmer]

@@Garage4age summed up by the previous comment too 🤣! People think the engine can only do peak power because all they ever see are engines built for peak power. It's like a confirmation bias or whatever. 😂

[@SidewaysGts]

@@Garage4age "This is what i've been trying to show on here for the last 2 years or so. can have an engine that works at both ends of the rpm range if get it right" Out of curiosity have you ever showed/discussed what was involved for retrofitting that VVT?

[@Adam-nv9zo]

Great job 👏. Truly shows how the well sorted and tuned the "good engine" really is.

[@Danleyson1]

That midrange disparity is impressive

[@dodenmanniskan8846]

Nearly the same amount of power and yet you way more drivability in yours. Absolument amazing !

[@sepg5084]

That small amount of high rpm power can make or break a race car, which has no need for mid range power. Apples to oranges comparison anyway but still impressive.

[@oscardeltoro898]

Great comparison. The Atlantic shows you more of an old-school approach at tuning back then where it was all or nothing. Showing with continuous data, research and development you can obtain close to a better average. The trick now will be to find the best cam that you can turn with the VVT. Depending on how difficult it would be to replicate these could have tons of potential. Many 4AGE are running the wrong cams for their setup and everyone could benefit from VVT.

[@Garage4age]

Yep, a lot of engines out there running mismatched parts, not just 4age. Thats where the power is had, getting it all working together properly. vvti setup is up and running on good engine with the best cam combo out of my pile of cams. was short on time when testing which would work the best. so didn't record any of it. but will do a video of said combo with the vvti when get time

[@manitoublack]

So awesome. The Atlantic is also likely to be down a few kW because those wide slick tyres always sap a little power.

[@AmirPomen]

Both were the best engine ever! 1 for the circuit Another 1 for the street 💪💪

[@TRDKhanbrothers]

Awesome Atlantic setup there, those are true and rare machines,this is one isn’t as insane as the others I have seen in Japan or Ausi, Wish I could gather all the parts to build one as I would love to own a 1900cc 4age 16v Your 4age is also impressive, not built like the Atlantic but the power is there and also very aggressive motor

[@jareknowak8712]

His engine is even more impressive than Atlantic, as a street engine, bc there is more mid range torque. His engine has wider usable power band.

[@TRDKhanbrothers]

@@jareknowak8712looking at this video again and comparing to his new video with his high comp 16v, yes you are right his motor is stronger than this Atlantic 😅

At 10k it just sounds like it’s pissing it in. Love it.

[@nick_parker]

Wow! That definitively shows how well sorted your 'good engine is! I'd love to see what tweaks you can come up with to push the performance envelope further.

[@Garage4age]

I'll be focusing on fattening up the midrange going forward. but should be able to hang onto most of that top end if all goes to plan!

[@luisramonrecarey]

Very impressive numbers on yours

[@themr2guy]

The G4A good engine is definitely a beast! Very well done for sure and making all that power while fitted in the confines of an actual road car. The Atlantic car has the benefit of fitting those smooth bend long tube headers so I expected more from it in the midrange. Very excited to see what you have in the works!👍

[@sepg5084]

They won't tune that exhaust for mid range, that race car probabaly won't use mid range rpm during a race.

[@themr2guy]

@@sepg5084 the term mid-range is relative…

[@MrEosmit]

I like to see these tests, find the results to be close to a CA18De with 4 port head. Keep it up

[@perrosdemaiz]

If I’m not mistaken, I remember these Atlantic engines need rebuilding at around 700 miles. You don’t get a super long life when you’re pushing 240HP. I saw a lot of holes in blocks.

[@Garage4age]

Yeah, its mostly the revs not the power. the guys that run them these days tend to limit them around 9500rpm. Which makes them last alot longer, for a little bit of a hit in usable rpm range. Back when budgets were high and super competitive racing it would have been worth using the extra rev's.

[@Bluterus]

IMO Yours is pretty close and would make a much better street car as it makes bucket loads more power in the mid range. The formula Atlantic is clearly made to run in the top end on a circuit. Pretty impressed by how close yours is and I bet it didn't cost as much.

[@JesseSpec]

Nice one! Always nice to have formula/prototype cars on the Dyno! The other day I did a bike engine proto, the revving is insane hahahah

[@T90isback]

A bit of difference in top end horsepower, a huge difference in mid-range torque, that's cool!

[@cloutdrilla8786]

This is the most legendary 4age ever

[@martinb2262]

Interesting comparison. I guess it comes down to what you want the car for and what you want it to do. A road car you want lots of midrange to make it punchy and useable. Race car spends most of its time WOT and at the top of the rev range. Peaky delivery at the top of the rev range would be a nightmare as a daily

[@3800S1]

Funny that. My next street (actually country road) car engine is based on a Formula race car. I have the cam for it that will form the basis but I am taking beyond what the Formula class was allowed by running a larger throttle (class ran stock 60mm) of 69mm (nice!) and much higher comp of somewhere between 12 and 13 where the class ran a very low 10:1. Also mine will have the factory intake pipe which adds somewhere around 5-10 Nm across the entire curve, the class ran straight throttle body with filter which results in a loss across the broad from my dyno testing. Mine will also have likely head improvements as porting has improved in the last 30 years and slightly higher ratio rockers. Not sure on what gains but I hope for at least 20hp over the 340hp they got in the early 90s but more is possible.

[@madxp9668]

your exhaust might be slightly more restrictive on the top end but u nail it at the lower end

[@stapernazza]

....you have to analyze the gear ratios and the engine rpm range you will most use..... may be that your engine is best if need mid range power (usually in rally car and street racing). For sure in track racing they can optimize gear ratio to have always top engine revs between the corners.... In these case their high revs engine is better.

[@Garage4age]

Yeah, as have said in previous comments. both engines are in the best place. my engine in the atlantic car would be slower, since would never see sub 7000rpm in race conditions. mines more of a all rounder. i also intend to trade a little more top end for more midrange

[@feral4mr2]

Just a couple of things - is the Atlantic on carbs and ign management system ? I bet the Atlantic is a straight cut gearbox , probably more rolling resistance with the Atlantic tyres - so +/- for true comparisons ..... but a good result ! Just out of interest, when the Ford Cosworth DFV entered the arena in 1966, almost 60 years ago, it produced 157 bhp / lt with 3 arc cams ! gradually moving up to around 170

[@TomoReso]

Well thats interesting, and impressive. I wonder how would the comparison look like with swapped exhaust headers. Formula ones look wider and longer.

[@Garage4age]

probably one of the biggest differences between them power curve wise, is the headers & exhaust. going by other setup's i've tested on my engines. The atlantic setup would make my power curve look pretty similar. lose a stack of bottom end and possibly gain a touch up top. I didn't measure but the atlantic look to be similar length if not a touch shorter and diameter is bigger.

Not to take (too big of a) jab at Loynings, but anyone can tell if it was 2 identical cars side by side at Tsukuba or something, that motor would lose out to yours. Peak numbers aside they're outright losing to a shed-built motor with half the money put in it, if even that 😂 Let us know how the BC rods are holding up when you've got some hours on them, I've been on the fence about those! Rebuilding a Gr.A motor and want at least as good parts back in it as it had when it exploded (by a previous custodian).

[@Garage4age]

Engine already had 2-3000km on it from when it was previously in the car. wasn't reving it quite as hard though. The atlantic would be quicker in its intended purpose. since would be in those last 3000rpm pretty much the whole time. something like a rally car mine would be the pick.

[@ToreDL87]

@@Garage4age 2-3k KM's at the pace I think you're putting on sounds *very* respectable! Reinforced beefier ARP bolts or did the 2K suffice? And yeah, I was thinking something like N2 AE86's, which actually has and is happening, guys putting in either FA engine swaps, or the TRD catalogue, and lost/losing out to privateer built Toda motors for that exact reason, better mid-range. Of course didn't mean to be utterly unfair, for one that car is t h i c (and well cared for, it found a good custodian), and for Toyota Formula Atlantic, up against it's peers, I reckon that Loynings motor would give *anyone* a run for their money! 😁

Im just curious can Hasslegren make a 4age Formula Atlantic for street use obviously without the race internals. Just to get like about 200hp or 220hp at max. Because doing rebuilds is no fun. I have a ae86 and would love that in the future. Pure goals

[@Garage4age]

imo if change anything from the "formula atlantic" spec. its not a formula atlantic. but thats not a bad thing. my engine has zero parts in common with the atlantic engine, other than the block itself. plenty of off the shelf parts out there now, to build something more suited to a street car.

[@rimka11]

It looks like you are reaching the limit on your 4age. Or are you going to eventually make more power on your engine than the formula spec one?

Some of its lack of airbox and the way the intake is tuned. Also the bump right at end isn't the engine.

hard to say. the atlantic car has a transaxle bolted straight to engine. so should have less loss that your standard rwd. but the slicks probably have a bit more rolling resistance than my road tyres. im also running in 4th gear which is 1:1. input shaft locked to output. the weird stuff at the end of runs on my car is the dyno starting to have a mare. doesn't like going that fast. you can assume it just starts to taper off slowly after 9500

Shifts are 7500-9000 between gears which is where most of the time is spent. The car only weighs 450kg so is more grip limited than power limited in the slow corners, by the time it hits the exit curb its up over 7500rpm.
