Does anyone else make a shaft like the GURU ? a friend told me that there is another thats made by a Mr Ken Shepps , he says its the same withe center bearing and all and also a lot cheaper .

 

That would be Ken Scheepers http://kenscheepers.com/2007_pre-season.htm

 

The other shaft is made by MPS.

 

So does MPS have a web site ?

 

http://mpsys.ca/MPSv1.htm

I think his user ID is MPS

 

Can't find anything on that site .

 

Not even a contact # or e-mail address?

Just f...king with yuh!

 

Do you guys think the 2peice e-shaft is beneficial to help with shaft flex with high boost/hp?

Jay7..

 

It's not neccesarily just high boost. It's great more or less for e-shaft flex in high loads at higher rpm's. The center bearing of this custom 2 piece shaft is the main feature that helps the most. Instead of the e-shaft having support only on the ends (factory e-shaft), it now has the additional support in the middle. Think of it as a piston engine crank shaft with multiple journal bearings that support it across the length of the shaft.

 

Sent an e mail and got no response , maybe I need to call !

 

OK , just got off the phone with the guy , he said that he isnt making them anymore .

 

Jay,
It helped me big time. You still have to clearance the rotors, but the e-shaft does its job and is worth the money.
Side note: I don't know if its worth the risk of the other guys with their prototypes. Not that they aren't qualified, but I'd go with whats proven. Just my .02

I'm so FREAKIN PISSED that I missed out on that GURU shaft the other day !

 

Same here

I'm going to look into having these made, just in one offs. I already have a machine shop ready, its just a matter of specs and R&D...

 

Don`t GURU make these any more??

 

Yes they do, but they do them in batches so it makes them harder to get.

 

Seems like I will have to go ahead without it , I'll put it on the "things I need to get " list so the next time I have to go in I'll have it handy!

 

Still looking and hoping !!!

 

u got PM

 

With the help of another forum member , I came across an alternative that claims to be similar and better than the GURU at a lower price , Ive put up two of our communications (he didn't mind) for your scrutiny , lemmi know what U think.


Hi Marcel

These shafts are not GURU items, they are actually better because the center bearing runs on a internal race which is pressed onto the crank, GURU runs the bearing directly on the crank which means there is no race that can be replaced if need be. They are made here in New Zealand by an engineer who does custom 1, 2, 3 and 4 rotor shafts used in engines worldwide. Price is 2300NZD plus shipping. The center plate will need to be machined for the bearing and oil feed, any good machinist will be able to do it. Instructions are included.

Hi Marcel

There is no brochure available. All advertising is by word of mouth.

The engineer who makes the shafts is going to send me a pic so I'll foward it on to you when I receive it. The shaft looks the same as the GURU item, pics can be found on GURUs website.

Weight is 6.5kg with bearing and 5.8kg without (lighter than Mazda).

HP is unknown but there are several 13bs making 800+ RWHP with this shaft.

Material is very similar to 4140 alloy steel.

Bearing design is needle roller.

 

From the description, the builder appears to be Jeff Bruce. He makes multi rotor e-shafts and lives in New Zealand. I can't imagine there being many people there that do.

I'm also very interested in this... price is much better. wonder what the wait is on one??
hey marcel, let me know what you think.. I'm looking in a month or two... just bought the 13Bre

 

I was thinking Kiwi-RE...

 

Another e mail from him with pics , The shaft looks identical to GURU's except for the replacable bearing race thats pressed on making it repairable ,..............

Hi Marcel

Here are the crank pics. I should also mention the journals can be ground to customer spec and the rear main journal is stepped and cross drilled, as per the factory race cranks.

Richard

 

Looks very nice... Can`t wait to get my motor from him...
