Enertia Plus on the Dyno

Anybody care to comment on the information up on that screen at the end?

Enertia Plus Dyno Test = 23.5 hp @ 64mph

Published onMar 9, 2012bywisdesign

Enertia Plus dyno test at Brammo HQ in Ashland, OR.   Dynojet 250i / Medium road load / No SAE correction.

Yes...any thoughts on the bolder part?

Good to see some test video.

The controller looked sexy... Between that controller and the sexy batteries, more and more I want a clear body Enertia

Someone email Proto...he will explain it all to me..

I like the bump up in HP...17 vs 23.5

I would like, as I've said before, 70mph. And 23.5 HP should do that...easily...I wonder if the power and top speed is controlled electronically or by the sprocket size? ...that said, I've taken the Enertia classic on the highway, so this one should do it too...but the Enertia and the plus really aren't highway bikes...they are commuter bikes that can do some highway in a pinch.

Any light bike is gonna be dicey on highways with cars and trucks... just a ton of wind to deal with. Doable, but ya gotta be a bit crazy (then again I've ridden my 220 pound 150cc Stella scooter on the highway quite a few times...so I can do crazy )

Thanks Gavin and Brian for making that happen.

Hey Brammo....Since we know you have some Enertia Plus motorcycles running around Ashland in testing....could you please throw one (or place it gently) onto a Dyno and put up a video of it...would love to see the HP and top speed.
Thanks

Brammo
Let me see what we can do before we head off .......

Gavin McCullough
Sweet!

As a side note, perhaps someone should be taking screen shots of that video. The last video that showed Brammo on a dyno didn't stay up for very long.

In this thread at elmoto.net, the following was said:

This was corrected rear-wheel HP...not sure what they corrected for since it's electric...

Exactly. When you do the SAE power correction for an electric, you just inflate the number by a substantial amount (depending on what the atmospheric pressure and temp happen to be that day).

Its very tricky to even turn SAE correction off on most dynos. Its off on ours, and its calibrated.

So it looks like "No SAE correction" means "don't inflate the numbers".

Enertia Plus Dyno Test = 23.5 hp @ 64mph

Dynojet 250i / Medium road load / No SAE correction.

No correction for sea level/air density/temperature probably.

I'm sure HP vs RPM plots could be created knowing the gear ratios involved and rolling circumference of the rear tire. HP vs RPM and 1/4 mile times and then real-world incremental acceleration figures (5-30mph, 20-30mph, 30-50 etc) are what I'd like to see, the E+ should be quite faster than my 125R was (which was capable of over 64 MPH and only had ~13 HP).

That's the on-board charger sitting on top of the BPM 44/70 battery module.  The motor controller mounts in the symmetrical position underneath the lower battery module and far away from the rider's precious parts.

The bike's current top speed is limited by the motor controller, but we are working with our motor controller partner in the UK to maximize the performance of the bike.  They have an identical Dynojet 250i (installed by Brammo) at their facility specifically for testing and optimizing the motor controls for Brammo products.  You are correct that the bike has more than enough power to exceed 70 mph, and I've been really leaning on the guys to allow a little more speed. We'll see what they come up with before final software release for production.

Posted to facebook re: torque

‎24" tire @ 62 mph is 860 rpm
http://www.wolframalpha.com/input/?i=%2862+mph+%2F+%28pi+*+24.2%22%29%29+in+rpm

23.5 hp @ 860 rpm is 194 Nm at the rear wheel
http://www.wolframalpha.com/input/?i=23.5+hp+%2F+861.2+rpm

Gearing is probably subject to change, but the Enertia Classic is 13:64, or about 4.9:1. If it's the same here, that puts the motor at 39.4 Nm at top speed (plus drivetrain losses).. looks like a completely flat torque curve, which was NOT the case with the Enertia Classic.

23 hp @ the rear wheel should get you a bit more than 62 mph if you regear it just a little.. : )

[Gavin]

Sweet...thanks Brian.

Will that affect delivery dates...vs a software release...

As in...is it new hardware (time and money) or tweaking and software (quicker and can be uploaded after the bike is in my eager little hands)....

Thanks

Gavin

You're welcome...

Though truthfully I really didn't do much...I think much more thanks go to Brian, Craig and Adrian

Ps...since Brammo has it on their Facebook page, I doubt it will go away

Ok, so the on-board charger looks bad ass and the batteries (seen in the newsletter) are killer sexy...

Can we get a clear body-panels version to show off all the tasty internals?

Some small details...

1. Mirrors are taller. I thought I would just go instantly to bar end mirrors, but I will try out these mirrors first.

2. The fuse area under the seat is changed. This might help with the flasher unit*... Which I've losened twice so far . You just have to push it back in and the blinkers work again...

3. The seat lock is still on the kickstand side...not a horrid thing, but it would be slightly better on the opposite side.

*if I ever go into a certain field of work, that will be my porn name..Well maybe just Flash Unit.

Anybody want to put the video link up at elmoto?

Ted (from elmoto.net) posted it today in that Brammo thread.

Really?  I don't see it....can you put up a link? Thanks.

Here it is, Gavin.  My advice is to not read the previous few pages.
