How to lighten a 61x or 62T flywheel?

[THRUST]

same both logos are on the flywheel .

are the TBM or RRP cast or machined?

billet aluminum

Man, last week we hear that MSD ignition curves are the same as stock, now we learn that lightening a stock flywheel does nothing...seems to be a pattern developing here. I'm gonna go home, rip off my B-pipe, ADA head, unport my engine, slap the OEM CDI back in and weld some more steel back onto my flywheel. Back to stock for me...this thing is gonna rip when I am done de-modding.:twak:

ROFLMAO! :dance:

LOL

That was funny

Dibs on the B-pipe :fingersx:

Timing control is done with the CDI, not with the flywheel.
My statement was that I verified the timing marks, meaning if you put the stator marks lined up at the factory markings, the timing is at stock Superjet specs.

Didn't the Rad charging flywheels also advance the timing by several degrees? Isn't this why your not suppose to run them with the Advents?? (thinking I remember reading this somewhere at one time)

thats exactly why i was asking before... i remembered another flywheel advanced timing IIRC

i think TBM would mention that on their site though if it did

 

[restosud]

tbm wouldn't dare say if it did or not.dealt with them before and there's a lot of bs in that shop.
and it ain't cheap!:dead1:

The advance in timing is caused by the different magnets.
In order to be lighter, the magnets must be stronger. That changes the field and thus the timing.
Perhaps Tim/TBM compensated for this by different magnet location on the flywheel compared to stock.

thanks all for the info.

once our shop slows down in winter i will spit a few of these things out and see what happens.

Just make sure you leave the largest radius possible on the face down by the hub. I have seen a few brake and it has been at the hub and they were machined with a sharp corner as opposed to a flowing radius. So when I machined mine I made a large radius and it has been good for a few years now

they dont actually advance the timing the same through out the curve
its not like 5 degrees all they way up
