Aasco and what?

What you don't know is the ignition timing that you are losing... I guess ignorance is bliss, because you never thought about it till now ;-)

I have used several LWFW in various cars of mine over the past 25 years. Never an issue.

I don't believe the argument that the FW is used to balance the engine ... a flat six like this has perfect primary and secondary balance, that's why they're so smooth. The cars I used LWFW on were inline 4's, and there were no balance or engine longevity issues.

As far as the "no power gain" argument, the car will rev faster IN GEAR in the lower gears, markedly so. I did some calculations before fitting one to my previous car, a Supercharged MR2, and in second gear (think autocross) the lighter flywheel I installed was good for a 6 HP gain. First gear would have been more than that, because the car revs faster in first gear. This was borne out after install by the noticeably improved performance of the car.

Additionally, the car just feels more responsive when the engine responds more eagerly, in gear or out.

All that said, I will not be installing one in my Boxster. I have no plans to autox this car. With the stock flywheel, this is a very easy car to drive, and I have hopes of teaching my wife to (finally) drive a stick shift. The LWFW would make that a pain, they *do* take a little getting used to.

Yes, you are probably right. Peace brother.

Jake, why would it affect the ignition timing, is the crank position sensor off the flywheel?

Yes...................

Thats the reason why you guys don't realize how these LWFW units impact the M96 in so many ways. The same goes for non OEM engine and tranny mounts. Couple these mounts with a LWFW and you have just created a huge compromise.

Anything else I'll say will be intense and strong willed and would be perceived as "pushing back too hard". I'll not say anymore.

FWIW the M96 isn't like most other cars or engines that many have owned or experienced. Treating this engine like it is something else is the first mistake that people make. Thats why they can't learn and make mistakes that they'd never expect. This is the reason why my engine classes are filled with 40 year Porsche veterans that have their asses kicked by these engines and lose their shirt on jobs all the time.

Jake, I appreciate you're frustrations, but there are people here who would like to learn. A brief explanation of LWFW-related timing and mount issues would be appreciated.

I don't understand how this would effect engine timing. The fingers the sensor picks up are mounted to motor side of both styles. The fixed portion is then bolted on the crank. The crank to pick up timing can't vary. The spring deadened portion of the DMFW is the friction side. The dynamics of this really looks like they are using the weight to stop gear clatter in the transmission. So like Thstone says using a sprung clutch put the back lash back at bay to some extent. The big difference form an engineering stand point is that the clutch can't supply as much force to the gears so like every video I've heard with an aasco installed there is an increased gear noise at idle and low RPM.
