I'm looking to lose my big heavy flywheel for something a lot lighter.. any suggestions? Active autowerke, bmp? who's got the best price for a dual mass Aluminum Flywheel for E30 318is.

thanks..

Let me know what you think but one of my suppliers could machine it down for you

Randy is in Germany at a car show. He will be back Thursday night or Friday.

You have 2 options:

1) get a 12pound aluminum flywheel from AA, Turner....

2) get an M20 325i single-mass flywheel and convert it to fit your car. It is 16pounds, which is much better than your 28pounder. You will need a euro 323 t/o bearing and an M20 starter pinion to install this (as well as 325i clutch/pressure plate).

Im just wondering, most of the increased performance from a LTW flywheel comes from its weight reduction..........but isnt 15 pounds really not that much?? I mean if 15 pounds does a lot for performance, then Im going on a diet!

it will increase your throttle response and acceleration times a lot! thing of it as running as a fat person, then running as donavon bailey

Getting a 10 pound lighter flywheel is not like removing something from your car that weighs 10 pounds. The flywheel is relative mass, and a heavy one causes a lot of inertia and slows down drivetrain operation. Lightweight flywheels have two advantages:

1) 1st and 2nd gear acceleration sky rocket, much faster spool up time.

2) Braking. Coming into corners when you are off-throttle, the engine RPM will drop MUCH more quickly.

An M20 15lb. flywheel is a big advantage over the M42 28lb. flywheel, but not as trick as the aluminum 12lb. unit.

Ok so as it stands now... My clutch, starter are in great condition so I don't really want to pull them off and buy new ones.

So AA, Turner, and BMP all have aluminum flywheel kits? what one is going to give the best price and weight reduction are they all made by the same company? and where in the GTA can I get this part without paying some huge markup.

PS what do guys think of Evolution on Dupont and Lawrence they seem to have a lot of toys for bmw's

slowered318....i am just wondering do you have an intake on your car? my brother is buying a 318is and getting it this week thanks to Riks Ryd...it already has exhaust and dinan chip...what do you suggest should be added next?

I have a K&N cone filter kit if he wants that, to be honest with you I don't like it thats why im selling, but some people swear by them. It worked great at night when it's cool but traffic jams it was brutal and I wouldn't put it on in the winter. Let me know i'll work a deal on it if he's interested.

As for performance on a 318is I haven't found any specific mod that really brings out the 1.8. I'm working on it and by spring I hope to have her up around 160 hp. olny 1/4 mile times will tell! The flywheel and some mild head work might do the trick as well as the chip and exhaust. Also he should look into adjusting the intake timing about 5 degrees advanced. the timing is fully adjustable on M42's I hear.

hope this helps..

Ok one more thing.. i'm wondering if anyone with an aluminum flywheel has had heat buildup problems with normal driving. is the aluminum FW strictly for racing or could it hold up in a traffic jam.

Another plus to having a LTW flywheel, quicker rev-matches for fast downshifts.

Also, 10 lbs doesn't sound like a lot, but having that shaved off rotating/moving parts increases performance.

Lighter pistons/rods/cranks/flywheels/wheels increase acceleration response. Wheels and flywheel making the largest difference.

Lighter suspension components/brakes/wheels(unsprung weight) increase suspension response and handling.

How would a light flywheel have any affect on the engine cooling? :huh?:

The clutch/flywheel doesn't heat up when ingaged, only when being modulated, mostly when you take of from a stand still in 1st gear. Unless you have a crappy/glazed clutch that slips. When you're at a stop light, you shouldn't have the car in gear and the clutch in anyway, it adds unnecessary wear to the throwout bearing.

Ok here is a breakdown of what i've found already

BMP - $720 usd full aluminum flywheel and hardware
Bavarian Autosport - $642 usd. same as above
Turner Motorsport - $598 usd same as above but machined by turner.

Now i've been told these are for racing only.. and the car will idle rough (well it already does because it's a 4) but anyways what do you guys think.. will it do for the street? and who should i buy from?

Also Bavarian has stock 89-91 E30 fog lights for $60 usd. (dealership wants $250 cdn.)

How you tell me!. I always sit at the lights in 1st gear and clutch in.

isnt that really bad for your tranny and clutch?

it doesn't ruin your tranny, it just adds wear to the throwout bearing that ingages the clutch

Look here (http://www.howstuffworks.com/clutch2.htm), scroll down to the "Diaphragm Clutch" pic and click the "click here" button. In fact, read the whole thing, and the transmission article too.

I guess it'd be easier to explain if you had one taken apart in front of you.
