It wasn't really an omission. A lot of what you're saying there is the stuff that gets passed on from person to person without having math done on it. It certainly is true sometimes but it is far from a universal truth. Take the heavy flywheel for the quicker 60' time. Let's use the numbers in this video where the lightest flywheel vs OEM saved about 8.5lbs and the flywheel is an 11" disk. at 4500 RPM that extra 8.5lb is storing about 4.2kJ but don't forget that you can't bring the RPM down to zero, by the time you're done pulling energy from it you'll be closer to 2500rpm giving you 2.9kJ usable extra energy. 2.9kJ is 3.88horsepower second. That energy will be released over about 1.5 seconds giving you 2.59hp more for that 1.5 seconds or even if you release it quicker you'll get 3.88 horsepower for 1 second. But then you have to turn around and pay that energy back as the car revs down the track because you have to spin that flywheel back up. The value of the energy in drag racing is worth a lot more at the beginning so paying it back a few seconds later won't cancel it out completely but mathematically this is miniscule. What's happening is that everything in the system works together from the engine, transmission all the way to the suspension and the chassis' weight distribution. In some instances changing the way the power is delivered by affecting the flywheel weight can be more beneficial than the energy stored would indicate but it isn't a universal truth. As for dampening the torsion on the crank that effectively changes the relative timing of the front cylinders from the rear cylinders it is a real thing and it's the reason that some engines have their timing assembly on the rear instead of the front. But that is also a case by case thing and these motors i'm working on use some pretty strong forged crankshafts so i will need a lot of power before it properly becomes an issue.

Sounds like we mostly agree. It's testing under controlled conditions to achieve repeatable results (math) and the math has shown that heavier flywheels (there is a ceiling to the weight too) can produce quicker ET's. One also needs to take into account that the heavier flywheel isn't just about the HP, it can also help to prevent the engine from bogging upon launch, which lowers the RPM of the engine, which means you have less HP available until the engine rev's up again. (a bad bog can literally bring you from 5000rpm you were launching at down to a 1000 rpm and result in you losing a few hundred available HP depending on your engine setup.) A heavier flywheel can also prevent rpm drop between shifts, which can also help ET as it won't fall out of the powerband as much. So even in cases where your may lose HP from a heavier flywheel, you can still gain ET. Even auto's that use smaller torque converters for higher stall speeds often incorporate an "inertia" plate on them to increase mass back up.

Thanks for the sub!

so many times "what clutch should i use" gets turned into "tell me what clutch you bought" with no concern for the application at hand. Hopefully this helps clarify some things.

@@FrankensteinMotorworks it will help some, but you are still going to get the same question🤣

@@e5141981 perhaps but now i can just point them to this video :)

I don't usually like saying stuff like this because it sounds disingenuous and like i'm pretending to create fake demand for it but i got a pretty small sampling of clutches made so i could see if they would sell well or not so depending on which one you want i may only have 2 or 3 of them on hand. It's not like they are flying off the shelves but you probably don't want to wait too long.

@@FrankensteinMotorworks you may only have 1 or 2 of them. I ordered a ceramic just now.

I personally believe it is a great combo. Unfortunately i do not offer such a clutch and i don't think anyone else does but it's certainly worth a search to see if they exist.

i did actually discuss the unsprung hub, the unsprung hub turns your transmission's input shaft into a consumable and is a terrible idea for a car that you are driving just as a normal car. unless the transmission comes off often enough to reapply grease to the input shaft they are just a bad idea.

You know what, you're absolutely correct. i reviewed this so many times because i knew people would try to poke holes in it and i missed this. Thankfully it does not change the overall sentiment that is being said.

I don't believe anyone makes that but i haven't really looked for it.

I'm actually working on a TL70 adapter right now.

Yes, that is the 2gr-fe flywheel i sell right here: frankensteinmotorworks.squarespace.com/shop/2gr-fe-all-steel-lightweight-flywheel the black coating is just an anti corrosion surface treatment and will quickly wear off of the friction surface as soon as it starts being used.

nice :) but the truth is he has two left hands because that was the best i could get from fiver :)

There are no 6 speed transmissions that bolt in directly or that have swap kits available for the SW20.

Twin disk clutches are a bit beyond the scope of the conversation for most people but a twin disk clutch just adds twice as much torque transfer assuming it's a full size clutch face. As long as it is paired with the appropriate clamping force for the torque it can make for a very light pedal pressure that can transfer a ton of torque. I've never used a carbon clutch and i wasn't able to find a number for the friction coefficient so unfortunately i don't have enough info to speak to it.

I honestly do not have any input on the automatic transmission. a few people have mentioned that there are upgrade kits but i don't know anything about them. converting a 2AR camry to a manual would be somewhat involved but all the parts exist, Toyota actually sold manual 2AR camrys in 2010 and 2011 using the EB62 transmission.

what do you plan on doing with it?

Gonna use it as street car n more of mountain cruise, plan on putting the 2gr in the 94 celica

I haven't personally run across an externally balanced motor in a really long time but i'm mostly playing with newer Toyota motors.

I refuse to drive automatics which certainly comes with issues when it comes to buying cars.

Nice :)
