What's better TBM or RAD flywheel?

[jeckert]

I am currently running a 61X Rad charging flywheel and wanted to change over to the TBM flywheel. What are your thoughts? I understand the TBM weights in at 2lbs. Does anyone know what the 61x RAD weights in at?

Also has anyone had any issues with the TBM?...and should I notice a difference switching over to the TBM?

Thanks in advance!

the TBM is lighter yes. i dont remember the exact specs on the RAD but its at LEAST 2.5lbs.
one thing to note is that the TBM only works with 62t stator. so you would have to swap out the 61x stator as well as the fw.
i doubt you would feel a difference back to back from the rad to the tbm. either way they are both better than stock
id take your tbm money and invest in something else.

If you are running a MSD enhancer do you still need to swap out the 61x stator for a 62t?

yes the stator and flywheel have to match.

Don't waste your money. You will never notice the difference from the RAD to the TBM. There is a slight difference in weight. But not enough to make the jump. If you do sell me your RAD. I can always use an extra. I have RAD flywheels in two of my boats and love em.

WOW!!!...I weighed the 61X RAD flywheel today it was 2.0 lbs the exact same as the TBM flywheel.

Great thread...So the 62T RAD should be pretty much identical to the 61X then?

 

[jeckert]

No, the 62T Rad flywheel will be slightly heavier than the 61X. All T flywheels were a bit more than X.

that one extra magnet can't weigh that much...

 

[masterblaster]

didnt even know there was a 62t rad

 

[OCD Solutions]

Just had my new to me 62T RAD weighed and it's 2.05 lbs.

62T TBM = 2.00 lbs
62T RAD = 2.05 lbs
61X RAD = 2.00 lbs
Stock 62T = 3.75 lbs

not bad,whats a jetinetics weigh,and is there any truth to as they get older the magnets start to wear out and the spark becomes weaker or out of time?

 

[Matt_E]

Magnets don't "wear out".

Magnets don't "wear out".

Then what exactly goes bad on them then?

 

[masterblaster]

well maybe weakin is the word then? Ive just heard this from a few sources.would be hard to test for certain though

 

[Matt_E]

Are permanent magnets really permanent?
Magnets generally retain their magnetism unless they are stored near power lines, other magnets, and high temperatures. Over time, magnet materials lose a very small amount of magnetism. For example, Samarium Cobalt magnets may lose about 1% of their magnetism in ten years.
Do magnets get weaker? How?
Several factors can weaken the magnetism in a magnet. If a magnet is stored close to heat, strong electrical currents, other magnets, or radiation, it can lose its strength. Additionally, high humidity can corrode neodymium magnets.

Good information Matt,

So are Jetinetics the only ones that seem to go bad? I haven't heard of any TBM's failing yet or RAD's for that matter.

 

[masterblaster]

well it deff gets plenty hot inside that front cover,how hot does it take to cause a loss is the ?

Thought I would add some pics to this topic. Here's a RAD side by side with a TBM and some weights for comparison.

chucky with x scream told me that you won't have to worry about using a timing light with the tbm flywheel, where as the rad flywheel, you may want to...(may be a little bit off)
