Default Orion V2 Endbell conversion

Ok....just to start off I am a seasoned racer with various A/B main finishes at top races........just so I dont get treated like a noob

Here's my problem, I bought the V2 endbell to run in 19t class at club races to avoid rebuilding twice a day, but when I installed it the motor is Very slow and pulls half the amps it normally does. Thinking it might just be the chemistry between the motor and endbell I tried it on my fastest stock motor and got the same results.......I broke in the brushes and oiled the bushings as well

Has anyone else had luck with the V2 endbell?

top races? yeah right! you must be a rookie!

hey chris,

jimmy has tried it on a monster stock, and it ripped on the robi. he didn't like it on the track, but i know he never put lap times to it. i may goof around with it the next time i'm in there. i'll let you know what turns up.

i like that idea on a 19turn. we're looking to head toward open mod here at the gate, and i don't want to rebuild every run or two either. then again, i may as well just buy a new 7x1 !

Chrisgt2- I have a few questions, I have done allot of testing with this endbell kit.
What springs and brushes are you using?
How long and what voltage did you break-in the motor at?

I had a chance to run one of these with a 19 turn motor on oval. I went as fast with it as I had a noral 19turn. The only thing I foudn was you have to gear up about 5 teeth higher than normal. It is a really effecient setup but does not have the rpm like a normal epic or yok based motor

I was using the hard spring on the + and med spring on - with the edge brushes.

Motor was broken in for 300 sec @2 amps on a LRP Pulsar

I dont know that gearing up 5 teeth would correct the problem.........

Use the medium/hard springs on both sides with the sprint edge brushes.

Break-in sounds about right.

You will want to gear this motor 1 tooth less because this endbell will give the motor more RPM.

Sounds like the brushes are not broken-in all the way. What are you using to check the RPM?

Dude are you for real? come on man !!!

the end bell has bearings supported differently then a conventional endbell and the aluminum absorbs some of the sound.
I can let you hear a motor that sounds like a dud but pulls 2200 rpm more then a motor I have that sounds like a ripper and it slower then the silent one. Dude harmonics plays a role in rpm the motor might be muffled but put it on a dyno and check it out for real. You might be surprized it faster then you hear.

You know I could rip you a good one with a comment like using your ear as a dyno!

But I'll spare ya. !
