lightened flywheel for aaz - results?

[gldgti]

hey fella's,
once again i'm pulling the trans on the mk3. clutch slip of doom, again. this time, i'm thinking about putting the 16V setup on it, in kit form from GAP. there's one kit that comes with a lightened flywheel..... i am thinking it'd be nice to make it a bit revv-ier. the car is soon to get a T3 in place of the k14, so its going to be revved more after that i reckon.... so, any thoughts/experience???

many thanks,
aydan

i did it. but make sure that if you get gasser *** to put on there, that you mark the TDC mark correctly. the gas timing mark isnt at TDC, its like 6 BTDC. and if you set pump timing with that, the timing gremlins will get you. i have a late 210mm clutch, flywheel, and pressure plate off a 1.8 gasser. after i figured out the timing marks, it was awesome. the difference in throttle response is amazing. but im running a short stroke 1.5, not a long stroke AAZ. you may not see the instantly improved throttle response like i did, but it will still work nicely. and BTW, if anyone was wondering, true diesel flywheels weigh alot more than gasser flywheels do.

thanks
im kinda hoping that i might gain a little acceleration in 1st gear and hopefully it'll make hear changes a bit smoother. off idle response is always slow in the aaz so hoping this might remedy that a little.

cheers

I'm running an AAZ with a K14 in a '92 four door jetta. When I finally did my slipping clutch, we had to turn the flywheel anyway, so I took some weight off while I was at it. Cut the flywheel from about 14 pounds to about 10.  Car seems to run a little freer at all times. I like it. I did notice that I needed to softpedal the clutch a little more, but not sure that the lower mass is the cause (should be), the old clutch was pretty much junk and was easy to slip. Next one I build will have more weight off the flywheel , and planning on a T3 too..

I'm running an AAZ in a Caddy with a T3 and a lot of other mods. Do yourself a favor and get an ACT clutch assembly and stay away from a lightened wheel. They shake like a bugger at idle and give no improvement that I could see.

an AAZ probably wont respond to a light flywheel like a revvy little 1.5 would respond to one. mine made a huge difference. just using a stock gasser wheel.

when i did my clutch upgrade to Kevlar and heavier springs i lightened the flywheel too by 4 Ib's
i does have the disadvantage of less torque for idle engagement but it does not shake at idle with
my fresh built motor.
It does rev quicker now though.

hmm mixed responses there... i suppose i'll just have to give it a go :evil:

thanks all for you input.

Im for it. it worked for me, but my engine likes revving a little more than a 1.9.
who knows, a 1.9 probably spins just as many R's as my engine, ive never gotten to play with an AAZ yet.

i dunno really,
i drove a n/a 1.5 for years and sure it loved to rev, but i never had a tach in it so who knows how hard i revved it.

i havent done th gov mod on my aaz, but it pulls well to about 4300 with the fuel screw setting i have, and the throttle linkage setup (i have ensured i can use ALL possible throttle movement). if you keep revving it, it'll go past 5000. i wussed out at 5200, but its not pulling there since its running out of fuel and boost, so i seldom go past about 43-4500.

the aaz stroke is so long, i just figure it'll only help to make it reva little freer, solong ans everyhting is balanced nicely.
