- Mazda Apex Seals vs aftermarket? Pre-mix vs OEM oil pumps? What are some of the key considerations needed to ensure rotary engine longevity in a Formula Drift platform, let's find out.
Note: Just to clarify, the 2:1 comment is actually 2 fl oz to 1 gal, making the actual ratio 64:1 which is still much richer than you'd expect hence the following discussion. Sorry for any confusion. The premix discussion starts at 4:10.
Powered by a 1.3L Series 6 13B-REW and running a relaxed 510WHP with 420lb-ft of torque at 19PSI from the BorgWarner EFR 8474 turbocharger we get some insight at The SEMA Show from owner and driver, Aaron Parker, a Formula D Pro2 driver, Pro1 mechanic, Netflix Hyperdrive contestant and all-round good guy into some of the decision making process and tradeoffs that go into a setup like this.
Controlled by an Adaptronic ECU and primarily running pump Ethanol fuel and an aggressive fuel to oil ratio, Aaron explains the reason for such a ratio and touches on why this particular setup can get away with it, along with his step up to the BorgWarner EFR 8474 from a slightly smaller EFR 8374 setup, and how with the introduction of Nitrous/NOS he expects to only see gains in power across the board rather than the usual sacrifice of lag vs power/size.
OEM Mazda apex seals and aftermarket seals like those from PTS are discussed along with Aarons basic guideline on what to always check and setup correctly in order to maintain reliability for the drift application of his setup. Massive gains can be had in performance when it comes to the performance of a rotary engine, but often at a cost in power elsewhere, so lastly we also get a quick and dirty rundown on the semi-peripheral porting and street port, aka extended port setup which gives him some extra power without sacrificing everything lower down in the rev range.
While we love a good LS, we are stoked to see this solid 13B drift setup going from strength to strength and look forward to seeing Aaron compete in Formula Drift PRO2 in 2020.

This interviewer is very talented. Explaining things to viewers while asking informed questions to the owner. Great work
Andre dont slip.
Andre has probably forgotten more about cars than most people know
A lot of people out there know a lot about cars, but Andre stands alone.
The interviewer simon Campaigned the fastest evolll in the world in the mid 2000s, built by himself and his company speed tech. Look up DOCILE EVO3
He the best in the business for sure.

lol waching this is after listening the podcast .... the look on your face XD 2:1 0_o
Followed by “ just dump it in there” 😂 👍🏼
Hahaha, that’s more like it…
I just love how the interviewer is always asking such good and pertinent questions. Every single one is a great question and he himself is really informed and helps us to understand every component and answer so well. I’m never disappointed after watching one of these and always come away with so much more knowledge than I came in with. Very well done, HP academy has done a great job from staff to lessons to even advertising and increasing the number of informed people in the car community. I’m honestly grateful for what you guys have been doing, real quality stuff 👍🏼
Nice job. Aaron gave a lot of good information about his rotary car. He looks like he really built it well. I am curious how often he has to refresh the engine. Drifting is hard on motors for sure. I have ran mine for over 4 years but I dont drift. Hope to see his car in action soon. By the way I did see Aaron and his car at hyperdrive. I wish he had another shot at it
That FD is so damn sexy. Wow!! I miss mine. I had.a 94 for a while back in 2000. Man, I REALLY miss that car. It was so amazing to drive!!
Great white buffalo
This car is magical. Seen it in person
Thanks for the helpfull info and great videos !!!
I love Aaron! Such a rad dude!
Rotaries have great reliability
Great informative videos! Thanks
Welcome to a real ECU, Aaron.
hey I recognize you from the forum.
2:1 WTF?.. that is ridiculous..
I run E85 on the street in my fd, S8 13b bridgeport similar power and boost level but run 150:1 using Maxima Castor927..
Too high a ratio lowers octane and is just stupid and wasteful, especially as a 1litre bottle is about $35 from my local bike shop.
I'm guessing he means 2 oz per gallon? Half a gallon of oil per gallon of gas would be ridiculous
@@dirtysp00ns Ahh yes, that would make more sense.
Americans have backward ass units of measurement..
More likely to be 2 gallons to one ounce though. Even then that's not "scale" as they're different units (gallon/ounce)..
I've run between 150:1 and 200:1
Converting US gallons and liquid ounces to litres would mean he's running a ratio of 188:1 which is normal..
That's assuming his nonsensical scale/ratio of 2:1 is 2 gallons of fuel per ounce of premix oil.
If it's as you say, 2 ounces per gallon that's roughly 93:1
@@darianistead2239 They definitely do have crazy units of measurement haha, I'm a Canadian from the land of litres. Used to run around 100ml of oil per fill up in my FC, can't remember what that ratio was though
@@dirtysp00ns Nova Scotia obviously🤦♂️..
I'm a Kiwi living in Australia. Both Rotary mad nations that use proper units of measurement too lol.
@@darianistead2239 2 gallons ethanol to 1 ounce oil would not be enough oil. ethanol has low lubricity so it requires more oil than gasoline. it should be 2 ounces oil to 1 gallon gasoline, i think it works out to be 64:1 ratio.
2:1 mixing!? That can't be right, can it?
Sorry for the lack of clarification there, 2 oz to 1 gal - Taz.
@@hpa101 that makes more sense! I was wondering how that would even ignite...
If my calculations are right, that's a ratio of 64:1. I normally run around 120:1 for my track car, but that's on pump fuel
2 to 1 premix thats unheard offf. Calling it bullshit. Most ive heard of is 3 oz per gallon and that being drag raced engines getting 50 psi.
2 to 1 premix???
think this guy is full of crap dosn't seem to know much at all
2 ounces to 1 gallon. that should have been made clear.
@@7sins979 That sounds about right. I used to do 13oz/10gal on a street ported 13b. Ran great forever.
Sorry for the lack of clarification there, 2 oz to 1 gal - Taz.
@@7sins979 cheers for mentioning that - Taz.
Donut!!
Good interview, points down for the opening message being one of rotary unreliability and the classic sh*t on a rotary engine from a piston dude.
We have 2 RX7's here, we like rotarys, but that is a common misconception/reputation regardless if you agree with it or not, particularly when it comes to the later RX8 RENESIS power plants. There are plenty of piston engines that have similar reputations - Taz.
2:1!? Ugh, that sucks.
2 ounces to 1 gallon. not 2:1 ratio that would be too much. they should have done a better job explaining that.
Sorry for the lack of clarification there, 2 oz to 1 gal - Taz.
These engines aren’t 2-stroke 🤔
True, but make power similar to a 2 stroke
Well they sure as hell aren't 4 stroke! Their fuel /oil mix requirement is similar to a 2 stroke.
Of course a rotary doesn't have "strokes", but the combustion process has a bit in common with 2 strokes.
The rotary engine is in fact a 4 stroke engine, however unlike a 4 stroke piston engine they complete a full engine cycle every revolution of the crankshaft (eccentric shaft to be accurate) instead of every 2 revolutions in the piston engine. This is why they're often generically referred to as a 2 stroke.
Steven Kelby I guess it depends on how 4-stroke is defined by the individual. Fact is rotary engines follow the Otto cycle and each face of the rotor makes the 4 strokes so to say.
Probably makes more sense to call it a 4 cycle engine imho
Should have asked how many miles has he done init and how often does it get built ?
Probably easier to count 'events'. I have seen elsewhere Aaron has gotten 40 odd events out of the engine before thinking about refreshing it. To be clear I would search/fact check that just to be safe, as it is something I read personally in passing not something Andre discussed with Aaron - Taz.
@@hpa101 nice thanks for info
The torque seems familiar
You guys got typo in desc. - "running pump Ethanol fuel and a 2:1 oil to fuel ratio" should be fuel to oil ratio
also what type of oil are they using? my guess is some 2T red oil
nah they actually put more oil than fuel xD
@@Nebbia_affaraccimiei 2 stroke? This thing is marine diesel!
Sorry for the lack of clarification there, 2 oz to 1 gal. When at a push I'm just getting words from the video to the description rather than dissecting anything, lesson learnt and cheers for pointing that out too - Taz.
@@hpa101 oh, so its 1:60 mix, because i use 1:40 (oil to fuel in liters) in 2 Stroke equipment/bikes, and if they are new, then 1:10-1:20 mix and it is smoky as hell
theres no way hes doing 20L E85 and 10L oil
I'm guessing he means 2oz oil per gallon of gas, that's all I can think of 🤷
Sorry for the lack of clarification there, 2 oz to 1 gal - Taz.
@@hpa101 ahhh that makes sense
2 to 1 premix is freaking bunker fuel lol. Seriously sweet setup though
2 ounces per gallon
Sorry for the lack of clarification there, 2 oz to 1 gal - Taz.
Can you explain why F1 cars illegally suck oil into the engines to increase power? In reference to oil reducing octane levels
Because of the additives. They can't have certain additives in the fuel so to get an edge they drink oil alongside those illegal fuel additives. But they also have oil limits. They got a certain ratio they can burn in a race.
Because they are the only engines besides Koenigsegg and a few exceptions that have nearly 50 percent or higher combustion efficiency. Oil vapors are extremely flammable and they are able to take advantage of the added lubricity from the oil and it burns not as bad as you would think. It’s only illegal for manufacturers to do this to duck emissions.
@@CorruptInfinityOfficial yeah that too. also in road cars it can drive you insane. i have a shitbox honda civic from 2002 that gloriously blew it's manual gearbox. it burns oil and it's simply a bother having to top it up every 2 or 3 weeks. now it started to leak it as well not just burn it. and people don't check their cars, the only time that bonnet is popped is once every service interval that has become nowadays once every 15-20k miles.
2stroke? nahhhh it is a 4stroke
The rotary engine is in fact a 4 stroke engine, however unlike a 4 stroke piston engine they complete a full engine cycle every revolution of the crankshaft (eccentric shaft to be accurate) instead of every 2 revolutions in the piston engine. This is why they're often generically referred to as a 2 stroke.
That was a little painful. Seems he dint know the reason people go to premix. Sump oil isnt meant to be burnt, 2 stroke oil is and is designed for that form of application, sump oil is not, but then yes, you can mix the ratio to suit. 2nd, does he seriously use two parts fuel to 1 part oil?? Or did he just reply wrong?? That seems waaaaay to rich on the oil side. He wouldnt need to turn the tyres to create smoke with that much oil being burnt.
Rotary engines are designed to burn oil from the sump, so it is meant to be burnt by design but correct oil must be used aswell as service intervals maintained.
We premix for a few reasons.
A fuel injector has better dispersion of fuel/premix in the housing creating a better lubrication barrier throughout the entirety of the housing.
Premix does away with the original omp and oil injectors which can fail.
Sump oil contains contaminents.
You can run higher grade oils like synthetics which you previously couldn't as they produce carbon deposits when burnt and can make rotor seals stick.
Your sump oil level is maintained meaning less frequent checks
He is actually mixing at of ratio of 60+:1 which is still heavy.
60+ parts fuel to one part oil or 2 ounces to 1 gallon which isn't actually 2:1 ratio.
Too much premix not only smokes alot but also lowers octane rating of fuel and knock will fuck a rotary real quick
@@darianistead2239 yes correct, rotary engines are made to burn oil, but sump oil which generally isnt made to be used that way compared with 2 stroke. Which is why we delete the oil metering pumps and run premix with a high quality 2 stroke oil thats made to burn this way. That ratio sounds a lot better but still way too oil rich.
@@ZLAKLR20B "sump oil" and 2 stroke oils have very little in difference.
Engine oil however will seperate or gum up in fuel if left in it for extended periods which is why you use 2 stroke oils specifically designed to be premixed with petrol or castor oil if using ethanol.
"sump oil" or more specifically engine oil is perfectly fine to lubricate and burn so long as it's low ash and not a synthetic..
Like I already mentioned, engine oil works in a stock rotary aslong as oil is of the right grade, oil level is maintained and service intervals are kept to.
The benefits of premixing I've already mentioned and are why you delete omp, not because engine oil is inadequate or not meant to be burnt.
