@@batman9592 The second turbo is smaller most likely because its job is to multiply the existing pressure in the system from the larger unit which has the duty of compresing atmospheric pressure and then some.

@@3xoticG4m3r That's what they say, but mechanical engineers have no basis and foundation of theory when they measure and they conclude that it is 13-B and they do not find a way for the engine to reach a larger size beyond being more efficient and free for both intake and exhaust and this is so due to the absence of valves and they conclude that it is 13-B and they do not find a way for the engine to reach a larger size beyond being more efficient and free for both intake and exhaust and this is so due to the absence of valves and it is rotating without limits and that is why it produces more the Wankel engine does not get bigger, it is only more efficient than any other piston engine because they are more limited to it and that is why it produces by alternating the movement of the pistons and valves; In the case of the valves, their time has been varied and this has resulted in better efficiency because it avoids being a barrier to flow, which is what the Wankel engine does best, and what it has against size against size, and it is at the same time; the advantage of the piston engine in this war of engines.
I don’t think I have ever saw an aftermarket ecu company grow at this rate. That says something about the product. I haven’t gotten my hands on one yet but I will say that have f the ecu and dash together is a genius thought. Keep up the good work fueltech!
Putting the ECU in the dash cluster also eliminates a lot of wiring. I think because of how good electronics have gotten in general with size and all would make it easier to get away with this today. With data buses getting rid of a lot of extra wiring also.
Trev Ohlson its really hard to get a 4 rotor to make good and reliable power. The ones that are, aren’t telling how they did it, the ones that are saying how they did it are struggling to keep them running. Both 3 and 4 rotors are super expensive. The fastest 1/4 mile rotary is a 3-rotor built by a Puerto Rican crew with an RX-8 that ran 6.3 IIRC, taking PACs record of 6.4
The more rotors the less efficient because the eccentrics bend, because they are longer and although they are thousandths of an inch but, still so affects the engine.
@@kyledavis8176 well you seem to care enough to do the math on hp/l bit don't understand that it acts like a 2 stroke Smh no one cares about comply aftermarket drag racing engine making this much power... You do know there are 1.4 4 cylinders making 2000-2500hp...no compound turbos needed
True, but is more complicated than that, you have 2 turbos, 1 is a high pressure the one is bolted to the exhaust manifold and low pressure that's bolted to a base, in order to make the high pressure feed the low pressure it takes some fabrication, redirecting the exhaust gases from high to low and boost from high to low, but yes in the diesel motors this system is being used for decades, caterpillar c13 and c15 are compound turbos from factory
@@jayknight139 that's a good question, the only thing I can think that will prevent that from happening is space, normally compound are installed in inline engines like Cummins or a single side manifold, duramax and powerstroke are V8 but this are full size pick up trucks and the have plenty of space and when they finish installing the compound there's no space at all, in a car is way more tight and more attachments, but in a race car is possible depending on the engine and chassis setup, but the main reason for compound is to develop tons of torque, there's 6.7L Cummins on dodge rams that can make over 2,500 hp and over 3,000 pounds of torque
@@Me-fj8sb which is why I wish there were more diesel swaps. But one version of the supra had twin turbos so although space is an issue its not impossible but selling kits may not catch on for a while.
Good to see Honeywell Garrett working with these projects (Nice work!) This type of TECH will eventually be picked up by the OEMS, and find it's way into your future car or truck
The 88 as single would not make more than 60psi of boost and will be over 100k rpm already which increases back pressure by a lot. The 106 can't be used as a single on a 13B because it will surge really bad, typically a 94mm is already entering surge already.
Has the 106 been tested? My guess no... The 106 will surge at high PR and low shaft rpm speeds. There are ways to configure the turbo and setup to achieve the desired boost levels without surge. Compound turbocharging is desirable at extremely high boost levels but it is terribly inefficient due to the design of the centrifugal compressor wheel. It's just no good a higher pressure ratios and the higher you go it just becomes terribly inefficient regardless if it's compound turbocharged or not. Better going 106 for 80psi and compound once you can't get a bigger either turbo to achieve the desired boost....
That is an amazing package right there and huge out put from just a 13b 🤯 I'm surprised to not see any intercooling between the two turbos? How much would this affect the set up and performance of the car?
I imagine this thing is running on alcohol of some description, which usually results in significantly lower intake air temps, negating the need for an intercooler. Im sure someone will correct me if im wrong! 👍
@@mechanicalmisadventures yeah it's a drag car it only needs to stay cool enough to go 1/4 mile it's probably also running on alcohol or methanol to cool it
IS ALCOHOL AND THIS IS COLD AND THE RACE IS ONLY BETWEEN 6 SECONDS THAT IS WHY YOU AVOID PUTTING AN INTERCOOLER, AND NOT ONLY OBSTACULATE AND EVEN THOUGH THIS IS MINIMUM BUT IN SECOND RACES 1,320.
Boa noite, eu estou com um eclipse onde montei um setup parecido aqui no brasil, uso uma .42 como minha turbina "pequena" e uma .70 como minha turbina grande, tenho oficina e estamos direto conversando sobre os beneficios da fueltech, estamos instalando ft300 em 2 eclipses. Mas no meu caso uso a central do proprio carro com um chip(ecmlink), tenho uma grande variedade de configurações e possibilidades de acerto com ela. Minha questão é, eu me beneficiaria instalando uma ft pra uso misto, rua/pista? e qual FT seria o ideal, sendo que minha central me da uma grande possibilidade de ajustes.
@@benjaminchartier6458 true, I've been building 5.9 and 6.7 Cummins with compounds for some time, but the only way to achieve tons of boost for racing purpose you need 2 turbos, but for regular commercial use, yes supercharger will do, I've done over 100 psi couple of time in my ram 3500 with a highly modified 6.7, dangerous but is only achievable with 2 turbos
My only question is how you stop the first turbo from over spinning and creating excessive air intake temps when high rooms are reached? Can’t seem to wrap my head around it.
Wastegates. The gates on the manifold charger dump into the exhaust feed to the atmospheric charger. The gates from the atmo charger dump out the exhaust.
@@Johnny-tq9no That doesnt change the amount of displacement. A 125 2 stroke and a 125 4 stroke for example, the 2 stroke fires every revolution and most likely has more power but they still have the same displacement
@@Be4tJumper nah, its about getting both turbos in their efficiency range and a lot of it has to do with pressure ratios, compressor maps, and not turning a turbo into a hair drier. For example, rather than boosting the atmospheric ~15psi of air pressure to 90 psi of boost pressure with one turbo (a pressure ratio of 6) and causing a variety of issues, you can use 2 turbos. One turbo (maybe 2 for even more airflow, like diesel dragsters and tractor pullers) to boost the atmos. 15 psi to 30 psi, a pressure ration of 2, and then a second (or third turbo for diesels) to boost that 30 psi to 90 psi, a pressure ratio of 3. Look into diesel compound turbos or the high performance academy videos on the 2000whp+ 4 cylinder dragsters. Of course, there's a whole lot more to it than I mentioned, its a science. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0jN2ExOW4J4.html He goes into a cool tech talk about turbos about 2 minutes in. Hope I helped you.

Anderson I was wondering how long till someone put a compound on a rotary with all the others popping up. Seems to work well. Are the hot sides still on the larger side?
Yes I agree, it works great for rotaries, both turbos have big exhaust wheels yes and could be even larger. Gtx5533r gen 2 88 with a 1.00 will be replaced by a 1.24 and the GTX5544r 106 has 1.40 A/R and worked great.
Awesome, I'm looking into the ft500 for my drag hayabusa, running mids 7's with nitrous but going turbo in future. Id like one for my FD also, it has old school apexi power FC. Only one at a time tho...
There multiple ways of doing it, the decision of not using an intercooler was because weight savings and unlimited boost, as well fuel atomization gets improved by hotter air.
Correct but adds weight to the car and can be compensated by a few more pounds of boost, but like I said, this is a project decision and really few people have tried all the possibilities to find the most effective one.

I actually came here to find out what's so special about this? This looks like a standard twin turbo setup to me (but then again I never bothered to learn what they mean by twin turbo, but I always assumed it was 1 turbo blowing into a 2nd) I watched the entire video, and never heard 1 thing about why is this special. *shrugs
