I have read of people using RX8 e-shafts and I am just curious to why?

Do people normally replace there N/A e-shaft for a RX8 shaft or would it be bennificial to replace my perfectly good S5 T2 e-shaft for an RX8 shaft?

 

All I know is that it is a half pound lighter. I'd say just wait til your old e-shaft needs replacement.

 

only thing beneficial thats been mentioned is the weight you'll be saving without having to balance the rotating assembly.

 

if that is the case then I have no need to replace my eshaft.. and I will just use it.. I am gonna use a lightweight flywheel ayways.

 

I am going to be building a turbo engine for my 10th ae and was thinking about using one. Do you have to do any mods to it for it to work with the 13bt i wasn't sure if there was any other difference besides the weight?

 

Titos, i though you had to balance everything if something is replaced that isnt the same on the rotating assembly? Because i wanted to get the rx-8 e shaft and a light weight flywheel for my T2 build but though it would need to be rebalanced. If someone could put in there input on this that would be great.

 

Pretty much. Besides weight, they're cheaper brand new than a TII eshaft.

 

You have to use the RX-8 stationary gears as well.

 

I don't think you do.

 

Why is it everytime i ask a question in a thread everyone ignores me....

 

im not ignoring you!! i actully have a questions about it also!!, they really didnt answer the questions here so thats why i opened my thread...but all i want to know is what does it do ? faster? more tourque? and do i need to use the stationary gears from an rx8

 

The stationary gears are only an issue with the rotors.
The RX-8 rotor & stationary gear set has a different tooth profile.

The e-shaft is balanced seperately.

 

oh ok thaks sureshot...so i wont need em, that will save 250.00...lol..

 

This is what I was planning on doing.

You do not need to have the motor rebalanced when using a new RX-8 E-shaft.

Or I should say, you do not NEED to have the motor rebalanced. From what I gather its a 'to build it right, rebalance it, but you can get away not rebalancing'

I probably will get a balance because I am going to use S5 rotors I got from someone else, plus a new Fidanza flywheel, and a new RX-8 E-shaft. The way I see it, I am not replacing one part, so I might as well do it. But I still think you can get away without balancing.

 

Oops - DP

 

I heard it had less flex, enabling higher RPMs.

This may be wrong though.

 

I have heard this too, but the more I think about it the more I think it has to do with the weight that enables higher RPM.

I mean, the difference between S4 and S5 is 1000rpm, and the only difference is the weight of the rotors.

 

well im going to use the rx8 eshaft....they way i see it now " lighter rotors , lighter Eshaft, lighter flywheel, who want sum?" lol....

 

Exactly. Less weight on the rotors enables higher rpms since the e-shaft will flex less because of inertia.

And if the e-shaft is stronger, than it can witstand more inertia to weight ratios.

 

So if I could find a E-shaft out of admantium, and find rotors made of ultra high temp withstanding plastic....

 

lol calm down wolverine...lol

 

I'll sell you my spare adamantium e-shaft for $400. Good for "OMFG THIS ROXORZZ!!!1!" rpm. PM me.

 

IMO not worth the 180.00 when I have a perfectly almost new T2 shaft..

 

Not unless you can sell your almost new T2 shaft for $180.

 

Ha...he said wolverine
