Default Aasco Midweight flywheel

Anyone running this midweight Aasco flywheel? My car is in the shop getting the G50 rebuilt and I'm trying to figure out a ton
of while you're in there upgrades and must do's. The Lightweight flywheel was on my radar but I don't think I can
deal with potential stalls. Even though the stalling percent is low.

Subscribed. This seems like it might be the best of both worlds.

Think Steve Weiner was working on something like this at one point...

Steve was working on a unit, talked about it at a 993 gathering and drive, but ceased doing such several years ago. I shall forward this to him for hopeful commentary.

I just emailed Steve about the midweight. He's retired, congrats to him. But, he's still consulting. Hope he chimes in.

FWIW I added a LWFW when I re-geared my tranny and the shop that did the work accidentally put in the wrong first gear and its way to high 2.5:1!) Even with that I don't stall in normal driving. I did stall a bit when trying to ease into a parking spot but now that I'm used to is I don't stall any more at all. However the aasco may help with noise a bit so there is that. I say give it a try!

Wow - You must be able to hit 50, 55 in first gear? Did they offer to replace it with the correct gear for you?

Hi Fred,

Looks OK, although I cannot tell you anything definitive from that pic.
Aase does nice stuff in general so it oughta be as good or better than
the OEM ones.

I believe they supply the mid-weight to Singer

Not sure if you can idle adapt the '95 993s. I was able to do that with my 964 successfully into a LWFW using UDT999. My car was adapted with a PIWIS the day before and it did not adapt well getting stalls frequently. The UDT999 from Jennkins performed adaptation better than anything else out there and I love my 964 with LWFW.

My brother has a 95 993 but he is few hours away and car is tucked away for winter..

My 95 993 is idle adapted. It’s running around 900-1000 rpm idle to compensate when there’s load from the AC.

Hi 911F1,
For me, the ideal alternative would be a slightly lighter flywheel that retains the vibration-isolating feature of the dual mass design. I wonder if it is possible to take an existing flywheel and machine off some metal from it, lowering its mass slightly while preserving its function. Seems it would be very cool for a street-driven car where the owner is looking for a perception of improved throttle responsiveness.

We're working out the details- I'm in Japan the builder is in the U.S. and shipping is time consuming and expensive. The builder is considering a vacation to Japan.... We'll see.

Going back to the OP comments... I asked about going to mid weight flywheel for my stock 95 C2. Build date in Sept 94. The person I asked was Jeff at Rothsport. He said dont bother with a mid weight if I am going to go with the expense. He told me to go with the LWF and if I have stalling issues he would fix it. Id assume a chip.

I had the LWF installed in Spring of 2020. No issues seen until the outside temps dropped below 50 F. Not sure why the temps made it more common.... Its now a bit annoying but will take back to Rothsport so they can adjust it when time allows. Would I do it again yes? yes!!!
