flywheel considerations

cto424 · 03-12-2008, 10:56 PM

Looking to get a Competition Stage 4 clutch anybody have any suggestions for the flywheel? I see that some people have the ACT flywheel but I have read negative reviews about their products. Any suggestions on what flywheel to get?

I was going to go with the Exedy Hyper Single but after reading Blueroadster's thread I changed my mind.

fidanza ftw!

cto424 · 03-13-2008, 12:09 AM

i was looking at fidanza's catalog and i'm confused is the flywheel aluminum or steel? and i did read up that we should stay away from aluminum flywheels b/c of them breaking and such. opinions on aluminum vs steel???

turktech · 03-13-2008, 12:19 AM

aluminum is really light compared to steel.. i wouldnt worry about it breaking

cto424 · 03-13-2008, 12:31 AM

does anybody have the fidanza flywheel????

jesus what what mods do you have to require a stage 4 clutch?!?!

stock lol. stage 4 sounds hardcore so he has to have it.

I have the Competition Clutch lightweight flywheel. I'd recommend sticking with the stock one - it makes daily driving harder, and I have some gear rattle with it as well.

stage 4 clutch is like 500hp nothing but drag strip status

ReDHatchyGuy · 03-13-2008, 08:34 AM

get a ACT streetlite if u wanna get one.. there not alum and its no so light as to give you DD problems like these super light flywheels that are like 8-9 pounds.. ACT makes great products dont let a few issues ppl had with clutch's keep u from buying one of the better flywheels on the market

***nbilyue*** · 03-13-2008, 09:17 AM

Yeah in for mods also. There was no problem with Blue's clutch, something wasn't adjusted properly during the install and that's what caused the problem.

cto424 · 03-13-2008, 09:54 AM

mods.....greddy turbo, custom 3inch downpipe, skunk2 exhaust, ingalls stiffy's, etc. for right now

more later like larger injectors, custom exhaust, and so on

so the reason for the stage 4 is so i dont have to upgrage again down the road. and competition does skip from stage 2-4

what was the problem with the install?

***nbilyue*** · 03-13-2008, 10:10 AM

I forgot to be honest, but he did tell me it was due to install error. I think a stage 4 is going to be a bit much for the Greddy kit though, especially for daily driving. I am going supercharged, but I'm only bumping up to stage 1. If I was you I would look at like a stage 2 that is still reasonable driveable and the ACT Streetlight flywheel so it isn't too light.

cto424 · 03-13-2008, 11:20 AM

i just PM'ed blueroadster so hopefully i find out what happened....and thanks for the info

What weight flywheels are you looking at? Whats the stock flywheel weight? Keep in mind there is going to be a loss in momentum of the flywheel, so it requires more torque to get going then. It does free up some RPM's, so the RPM's with or without load will increase a lot faster. But look at the otherside too, they're going to drop a lot faster, especially shifting between gears, and most of all, when you're trying to slip the clutch and get going from a stop or crawl in traffic. Torque is a big key in the weight of the flywheel. The lighter the flywheel, the less rotational momentum, and the more torque is needed to get rolling - low end torque. For instance, rotaries have practically no low end torque. Trying to drive a rotary with a light weight flywheel is extremely difficult.

What about boost? Heavier flywheels are better for building boost. On the dyno you're not going to notice much difference because they're inertia based, but on the street (and butt dyno) there will be a difference. Full boost often hits lower under load than it does on dynos. When you reduce the weight of the flywheel there is less load and again, less momentum, so it takes a little while longer for boost to build.

What's the material of an ACT Stage 4 Clutch? How many pucks? Sprung or unsprung? These are all going to be factors in driveability - especially with a lightweight flywheel combination.

cto424 · 03-13-2008, 12:03 PM

6puck, sprung, not sure on the material

the stock flywheel is 15lbs, the ACT flywheel is 11lbs, the competition flywheels vary from 8lb to 10lbs

good gawd mike knows his shit!

15lbs is already a light flywheel. For boost, I'd try to keep it in the 12-15lb range. The competition flywheels I'd fear are going to be too light. Even though you have an increase in torque with the turbo, you dont see that increase in torque until say 2500-3000RPM (Do you have any dyno charts? Im just going off of an average) which is with it under load. That lighter flywheel is going to make it a little longer to build your boost. Especially when revving with no load to get going.

A lightweight flywheel, with a 6 puck clutch is not going to be a lot of fun when driving in traffic, or on hills, or at stops.

Just some food for thought.

^^^thanks for the replies...i understand...my brother has a similar config to his TC...let me see if i can get the charts scanned so i can put them up

vtecmike1 · 03-13-2008, 02:16 PM

the whole 12-15 pound theory for boost wouldn't apply to supercharged cars since boost is built right from the crank not exhaust velocity correct? supercharged cars increase boost per rpm so if it revs faster they should boost faster ya? im tryin to decide between a 9 pound exedy and an act 11 pound streetlite.
