Light Flywheel

Just wondering what everyones opinion is on different light flywheels. I am currenly going to be putting an engine in, and since the engine is out, I would like to stick a lightweight flywheel on. Any experience, opinion, info exe.. would be very helpful. Where you bought yours, how much, did it make a noticeable difference for you, and such. Thanks


Oh, and if anyone wants to sell me a light flywheel for a s4 N/A let me know.

Later

I bought the SR Motorsports. It's alluminum with a replaceable steel friction plate. If it ever wears out, I just replace the 70$ friction plate. And it's only 9.5 lbs.! I bought it when it was on sale with an ACT clutch. I think it was 800$ for both.

I had one installed on my street port 12A, lots of fun.

Having one installed on my 13B turbo FB today, both were about 12 lbs.

I have the 17 pound steel racing beat. I was going to go with the SR Motorsports like E6KT2 has but I was told its not so great for daily driving.... dunno though.

flywheel

i have a 12 lb aluminum on mine. It is a really nice thing to have when at high RPMS. Low end power and it is not as easy to launch are the only downfalls that i can think of. But at high RPMs, the engine revs much quicker. Any rex shouldnt be at low RPMs anyways, so its all good goin with a light flywheel.

I looked at the SR Motorsports 9.5lb flywheel. It seems like the best deal since it is only $350. However I am worried about it being too light. Does anyone have/had problems driving with it. My car is only N/A so I already know I will not be making tons of HP like turbo guys If you do have do have it do you recommend it, or should I just stick with the stock flywheel. My rebuild engine I am putting in will have a light port and pineapple sleaves.

Anyway Thanks

Would love to dyno once I get it back....I had it, broke it in, (had it broken in lliterally also 2 days after I got it ) Then went back to Ito at J.R.'s Rotary about a month ago to fix a bearing problem in the trans. So fasr I havent gotten it back. So who knows when the dyno will come. Nick = Not a happy camper

jdmfdrx7///For some, myself Included, the RPM's drop as fast It accelerates. It drops fast enough to cause the car to shut off due to the ECU not being responsive enough. If this happens to you, bumping up the Idle will correct this.

thanks sliverrotor , I am really thinking about buying the 9.5lb flywheel, but was trying to figure out if people are really pleased with it. If it a made a noticable difference in their response of thier car, and if it is streetable enough for daily driving.

Thanks again

If this is your daily driver, and you have to deal with stop and go traffic...

DO NOT GET ALUMINUM. Excessive amout of slip clutching needed to keep from stalling out your engine, so your clutch life will be really abbreviated.

If you live in an area you rarely have to deal with stop and go driving, Aluminum is fine.

My first move was for an Aluminum one in my FB. I COULD NOT WAIT to get it out of there and replace with lightened steel. MUCH better driveability and I really couldn't tell that much difference in seat of the pants acceleration.

Ultimately, it's your choice and tolerance level.

Good luck!!

Unless the flywheels were different weights, there shouldn't be a difference in drivability and amount of clutch slip. Most alluminum flywheels use a steel friction plate that is also replacable. Lighter flywheels do require more clutch slip, so you replace the clutch more often. The advantage is that instead of replacing the entire flywheel as it wears out, you just replace friction plate.
