Wow...

turb0mik3 · 11-21-2011, 01:24 AM

Wow, that is pretty shniffffty. I don't know if I would ever bother using it, but still really cool! Just become friends with a dyno shop, haha.

I am but i just saw the article on it and thought it was cool. For just about $1200 you can have a realtime dyno.

Jeff@TopGearSolutions · 11-21-2011, 01:31 AM

This is neat! I gotta get some more info on this.

$1,200 bucks is around 5-6 track days.

Yeah and try to get the $1200 pice tag down for the n54 community

Very cool, it uses the same technology cyclists have been using on their bikes to measure wattage. The cycling ones are accurate up to about 1-2%, so I don't see why this would be a different. Very cool stuff, especially for a guy like Shiv, who constantly tunes his car.

Considering vbox is within 1 mph in trap speeds and nearly dead on in ET, plus the easy installation and price, I think I'll pass. But just my opinion.

Look's like a joke,I don't believe it till I see it.

I can get AEM. I'm more curious who is willing to put in the wrench time though. It looks quite tedious, no?

But besides that I think they have to make one specific for our application from what I was reading.

Alex@Helix · 11-21-2011, 02:18 PM

I dont think this is new technology. Ive seen one like this ( a lot bigger though) that had you connected the car directly to the dyno. I believe they used to be like 10k so 1200$ is not a bad price

PINeely · 11-21-2011, 02:34 PM

Lol, the "Dyno-shaft."

Tiago@VRSF · 11-21-2011, 09:04 PM

Saw this at SEMA. Looks great but will definitely have to be application specific.

But, the vbox doesn't calculate hp and tq like this device.

And what they fail to mention is that fact that the driveshaft is already balanced and adding weight to it is doing nothing but hurting you. Gonna wait and watch as people bust driveshafts and wonder why.

Good point. I bet those silly engineers didn't even think about that.

Funny this engineer did think of that. It is really funny watching everyone jump on bandwagons whenever the aftermarket stuff is released. People instantly assume that the company has more engineers than the OEMS and that they did all sorts of testing on durability. Take a look at a driveshaft once in a while and see how small the balance weights are. Now tell me adding that much more weight to one end isn't going to effect anything. There is a reason I took multiple classes on machine/engine design.

ya and your not counting the tickets you'll get while using this "onboard" dyno hahahah so lets call it $2500

Wedge1967 · 11-22-2011, 02:24 PM

Haha, cool toy. If you had a full time track car. You could see how the car was performing and make adjustments to ensure you're putting down as much power as possible for the conditions. But for someone's daily driver? If you have that much money to burn you may as well buy something useful like a set of brass balls to hang from rear tow plug.

Then you should also agree that the rotational inertia of a driveshaft is actually quite low when compared to something like a wheel which also uses small counter weights, since the radius of the driveshaft is relatively small.

I think how this affect driveshaft balance has a lot more to do with placement. It would have less of an effect on the balance if it is placed at either end of the driveshaft vs being placed in the middle.

I agree it will be smaller compared to a wheel, but that is not what I was going for in my argument. I've seen plenty of high hp cars twist/destroy drive shafts which is why drag strips make it mandatory to have a driveshaft hoop when you get to a certain point (can't remember exactly when but you get the idea). Also if you think that the part AEM has shown will weigh the same as a small weight I'd highly doubt it.

I am more jumping on all the people who instantly assume that companies do all sorts of durability testing comparable to OEMs, which is not the case. I work for a company who provides parts to OEMs and the sheer amount of testing to validate new products can take a year or more to develop. Do you really want to make the bet that aftermarket companies are doing the same type of testing? Just saying, buyer beware especially on stuff like this.
