Fly Wheel? Racing Clutch?
I have a quick question what is the advantage of the light fly wheel and is it somehthing that would be worth doing even if i dont have any engine mods and what about the racing clutch what advantages does that have and where can i get one? whats the best? in the fly wheel and the clutch?
A lighter flywheel will allow the engine to rev up faster. This helps reach the powerband faster. A performance clutch has more gripping power. There's less chance the clutch disc will slip. I'm happy with my ACT clutch and flywheel but I don't think they make anything for the A20.
No projects. Life consumes my time and money.
The lightened flywheel also reduces rotational mass. From what I understand the less rotational mass on the crank the more hp to the wheels.
go to www.clutchnet.com they have applications for your cars, the great thing about Ally flywheels and aftermarket clutches is they last longer and take more abuse, they are also not that much more expensive than stock parts. Clutchnet do the best kits available and are so well made i've not seen anything better or cheaper. They also do a huge range of disk materials too and everything from mid spec plate to heavy duty race.
The ally flywheel is handy as it has replaceable ring gear and flywheel face so you'll never have to buy another flywheel again unless a clutch fell apart and is phyiscally damaged. Also when it's done it's done you can happily change everything else knowing that whatever you do to the engine NOS turbo car upgrade your clutch is never going to slip and the fylwheel will give you extra pickup and not wear out quicker.
what kind should you get? (clutch) solid hub or sprung hub? and as far as clutch net goes when do you know if you should use yellow or green? and how about pressure plates?

the clutchnet dual diaphram pressure plate and 6 puck sprung hub will handle anything you can throw at it... and i mean ANYTHING. I run that clutch with an 8lb aasco aluminum flywheel and love that combo. If you want the car to be streetable get the sprung hub, the unsprung hub is a bitch to drive, i hated mine. Clutchnet>*

which pressure plate? they have green, yellow, and red lolOriginally Posted by AccordEpicenter
umm i think its the biggest one they have... would def qualify as a red one

Yep i agree don't mess about get Red theres a couple of different red ones though pedal pressure isn't that bad though still. The organic sprung hub is good but if you have a sprung hub you need to get the inside of the flywheel machined out as it hits the inside of the flywheel your okay with solid though.
Accord epicenter what flywheel you running 2G lude 1.8 or 3G accord a20? Not sure which is best to get the lude flywheel or Accord one? clutchnet have both bought a D16 one by mistake thought it was the same bolt pattern then discovered they only had 6 holes doh!! Thank God for Ebay!!
will i even need the transmission upgrades, really besides the cam and port and polish (look at my sig for my setup) i'm doing pretty much basic bolt ons. And even if i do go with new tranny wouldn't i be able to get away with like the "green" performance, i've also heard that a lighter flywheel is pretty much like adding 10-30 horsepower to the wheels so i dont know, enlighten me! and talking about getting the flywheel machined? would that still be neccesary if i got an aftermarket flywheel (and clutch and presure plate), wouldn't they all fit together like one happy family?

If you get clutchnet flywheel and clutch will be fine only an issue with stock 2G prelude flywheel as far as i know not sure about stock 3g accord one?
flywheel : i hear that if you get an 8-10lb flywheel, it accelerates awesome, but it also decelerates quick too. what do you think would be BEST for daily driving, i dont have any REAL mods done to the car, what do you think would be good. i was thinkin around a 10-12, but i dont know. i want something that will help with acceleration, but i still want to be able to use as daily driver...

yeah i agree with him, really i'm just putting an exhaust, a weber 38, tri-flow regrind, and maybe some headwork, this however is my daily driver, that i take to school and work. so w/e
and the less torque
wait, so theres less torque??? or more??
V12 Supercharged Toyota Accord
Yeah, explain that one to me. I would think this is the same general principle as the heavier the wheel the more torque it takes to get them moving. As the flywheel gets lighter the engine looses less energy trying to spin it and that get's passed along to the wheels. I can see maybe at idle or crusing speeds where it might require slightly more power to maintain speed since you won't have as much kinetic energy to keep the crank moving. But I wouldn't think that would apply under heavy accerlation. Of course it's been a long time since i took physics so tell me why I'm wrong
torque and hp are inversely proportional. So the more hp you have, the less torque (unless you also alter your gearing). So what you kind of need to decide is, do you want more speed, or better acceleration? It's actually a bit more complicated than that though. Different gear ratios will give you more torque at different rpm ranges and in different gears. That's why the same car can perform differently depending on how it's gearing is set up.
You can think of horsepower and torque in these terms: horsepower is how fast your machine can go. Torque is the inevitability of the "twist" between your engine, transmission, drive gear, and wheels. That's why big trucks can haul such heavy loads, but they don't go very fast. They have alot of torque, but not much hp (comparitively).
That's also why a lighter flywheel gives you more hp, and less torque. A lighter flywheel makes it easier for the engine to turn your transmission, but the lack of mass reduces the inevitability of the rotation.
If you're just looking to go a little faster, the usual bolt-ons should be sufficient for you. You shouldn't need a performance flywheel or clutch unless you plan to race the car. One thing you can do fairly easily to boost your speed is reduce your car's weight by removing unnecessary interior items....this mod is also free, but it tends to reduce your personal comfort as well.
Hopefully some of that made sense....and hopefully some of it was even right lol.....
Like I said before, It's been a LONG time since Physics class, but isn't HP a function of torque?

HP = (Torque * RPM) / 5252
Therefore, torque and hp are not inversely proportional. HP is a factor of torque. The reason big rigs have much more torque than hp is because the engines don't turn a lot of RPMs. I'd be surprised if the redline is anywhere over 3000-4000. Why do you think they have 18 speed transmissions and when one is accelerating next to you, you can hear them shift every second or 2?
No projects. Life consumes my time and money.
most of the big trucks I drove redlined at about 2700 rpms.
Sorry....apparently I mispoke. Torque and speed are inversely proprtional.
from the following link:http://www.procivic.com/pages-horsep...que/index.html
The Transmission Effect
Now comes the tricky part: the transmission. The fact that our engines cannot rev indefinitely means we must have transmissions to allow our wheels to keep spinning faster while keeping the revs under redline. A transmission essentially makes engine torque meaningless because it can multiple your flywheel torque to any amount it pleases, and is only limited by physical gear size. This is because gears can be arranged to increase or decrease their lever-arms and thus change the final torque output.
However, don't go out and buy yourself a giant gear set just yet: transmissions cannot amplify horsepower. This would violate the law of conservation of energy and change the world as we know it. Instead, as we increase the torque output for a certain gear, we decrease the maximum speed that we can have in that gear. Would you want your Civic to have 400 lb-ft of torque in 1st gear but only be able to go 8 mph in that gear? Probably not. The opposite is also true; as you decrease the torque output of a certain gear, you increase maximum speed, assuming you can reach it. That is the main reason why you accelerate slower in higher gears.

When you see that formula, what could possibly make you think they are inverses? An inverse would require division, not multiplication.
Ok, here's how to prove it to you.
B16 = 160 hp @ 7600, 111 lb-ft @ 7000
HP = (111 * 7600) / 5252
HP = 160
If I add 10 lb-ft, my hp jumps to 175.

This seems to be a good read on the subject although it doesn't address the flywheel issue.
Perhaps your thinking all other things being equal altering the gear ratio will either result in more hp and less torque or more torque and less hp at any given rpm?

I actually edited that post since you quoted it.
However, I do find it interesting that below 5252 rpm, torque will always be higher than hp, and above 5252, hp will always be higher....
i always thought a lighter flywheel wouldnt give you any hp or tq, it just lets you get to you max hp a lot faster. isnt that how it works????
Any time you make changes to the drivechain you effect hp/tq at the wheels.
