AEM Dyno-shaft permanent inline driveshaft dynamometer

[rcfanatic]

Anyone seen this dyno tool from AEM? Doesn't look like it will fit our cars but hopefully soon someone will make one that does. This would be a dream for tuning

Very cool, but I don't see too many people spending that kind of money on their E30's...

Yeah I just noticed the price tag. Seems like the best option though if you can't find a place to tune your engine for you

There are like six e30s in the world that make enough power to even care about it.

good price, but I will wait for boxing day....

With that logic no one would ever get their cars painted, big brake kits, 5 lug conversions, turbocharging, etc.

no load brake capabilities, no care. :p

plus I could afford an entire DAY on a chassis dyno at that price. normally you only need an hour or two. it's a neat idea but one day the things will cost $200 and then it will be a neat toy.

interesting----- i rememember seeing this idea presented at televised sema event I believe. Prob about 7-8 years ago by a 16-17 year old kid. He had a working prototype he built in his school lab or something...details are fuzzy but back then it was off by 5% and cost him about 2-300 to make.

hope he got a sold sum plus royalties for his invention.

I don't see how it would help you tune a car. You would still have to be doing high speed runs somewhere and you would still have to be logging AFR, Alpha, throttle position etc. Might as well do it on a dyno with a load brake.

you could legitimately use it on a racetrack or drag strip.

However, I'm assuming professional teams already do stuff like this, considering how much computing and logging power they already have.

it's unclear to me what the market for this is, other than a cool (and expensive) toy. I want one but I don't know what I'd use it for. :p

nobody knows, not even F34R...

Don't you get a load brake from wind resistance and the mass of the car? :p

I mean, the facilities required for using this effectively are significant - basically you need access to a runway. On the same token, though, I'd think you could get a lot of useful data that isn't available on a dyno. You know, like whether or not that intake actually works.

[nando]

you can do that without a $1200 tool if you can datalog already. all you need is an IAT measurement. :)
