Evoms, Proto, bbi, GT3RS all underdrive the pulley
Underdrives the engine accessories at the OEM specified range. ~15% (Same as the OEM GT3/RS)
The harmonic balancer doesn't underdrive anything and its main performance benefits of using the proper harmonic damper are considerable. A properly functioning damper stabilizes camshaft and ignition timing. A reduction in twist at the end of the crank also stabilizes the valvetrain. The result is more power and longer engine life.

I was at the shop a little while ago and felt Abes turbo. Kinda unfortunate and lucky that tech caught that too. I turned the turbo myself and every few turns it felt like the wheel was grabbing metal, seems like a mchining issues in the wheel or the cover itself.
I have also been contemplating on getting a crank pulley, I was going to go with the EvoMS, then I saw few post from Esmotor and they run the harmonic balancer pulleys. Both seem to be reliable resources. I do not want to do the RS one because I do not want the underdrive, I want the alternator driven at full speed.

The ATI harmonic dampener is a dampener, not just a crank pulley. All the others mentioned are just crank pulleys. Porsche's design was to use a dual mass flywheel to act as a bit of a dampener on everything but the RS engines. The problems show on 997.2 RS engines with the variocam actuator bolts backing out, and on 4.0L stroked builds with oil pumps being eaten.
The Dampener has been on my 4.2L GT3RS for 2 years now without issue. It's also saved Champion Motorsports 4.2L GT3RS from repeated oil pump issues.
If you're not using a dual mass flywheel, the dampener is cheap insurance on a very expensive engine...
Contact me on rennlist or via PM. I'm not a vendor on 6 speed and don't want to get busted!

Spoke to the guys at Undercover and arranged to have the ATI balancer installed..
Thanks a lot Jamie_GT3 for hooking it up.

Better safe than sorry. Thanks for the input.
Jamie already shipped it out lol. Garth should have it by Wednesday.
As for the oil dipstick , I like the idea of being able to check it manually, but I'll have my Motec dash in the car that's constantly watching my oil pressure ... And the oil measuring sensor on the cluster .
did you get the turbo back from Tial yet?

No not yet.
They just got them today. And going to work on them ASAP.
Everything else is almost complete.
Garth is going to fabricate my BBI exhaust to operate as a Valve cut off .. Similar to yours .

Also had to get me the CAE shifter to keep me on point, when I need to school a few cats lol.. Helps prevent miss shifting because of its accuracy and it save you time getting into gear. Attachment 428711

The Motec dash would be getting all its data from the PROEFI, the PROEFI has its own oil pressure sensor..
The Motec dash, gets wired to the CAN bus channels on the ECU, and programmed .

Yes, the Motec is a CAN bus based system. I'd have to check but I just don't recall oil level as one of the CAN outputs hence my question how you plan to monitor and display the oil level dash measurement with Motec, if I'm understanding it correctly.

I guess what I'm asking, where is the proefi oil pressure sensor getting its oil pressure input? Are you tapping a separate source on the engine somewhere or removing the factory sensor and installing the proefi sensor in its place. Yes, the Motec is a CAN bus based system. I'd have to check but I just don't recall oil level as one of the CAN outputs hence my question how you plan to monitor and display the oil level dash measurement with Motec, if I'm understanding it correctly.
