Okay this is all based in theory so give me a break for not having all the details...or any of them thought out. i just thought of this about 5 minutes ago.

Basically you put a car up in the air via some sort of support system. You move a large cylinder that is quite massy(simulating a load). On this cylinder there are placed a large number of sensors that interact with a lazer. As the lazer hits the sensor it would be able to mark the time verses the distance between the last sensor giving you a velocity...basically the closer together they are the more exact the instantaneous velocity is. I dont exactly know how one would compare it to rpms...didnt really think of that yet.

Basically the main flaw is, you would need to find a cylinder that had a very similar load to a very smooth road(friction). I know this seems like a hack idea, but it was my hack idea of the week :P

Wow. Just take the ****** to the dyno. :P That seems like soooo much work and R&D for something so small. I guess this is Homemadeturbo and if you can find a way to do it cheaper more power to ya.

Wow, that car must really be slammed when it's on the ground. The wheels are tucked even when unloaded!!!

Way to think outside the box, but I think the best answer is in the box... come back

Wow, what car is that on your dyno? It looks like one of the new Lexus Space Twinkies. I don't think the construction would be the hard part, I think the electronics would be the hardest.

I still think my idea of burrying a honda upside down in the ground is better... very nice drawing though.

i hate you guys


No seriously, it was just a thought...the massy cylinder i would imagine would be the most expensive part of the whole ordeal. I bet a guy like J. Davis or some guy that is electrically inclined could figure it out. basically the way i was thinking of doing it was the laser hits a sensor it starts a timer...then hits the next...logs that time and resets the timer and so on...you could actually put this in like a wood frame reinforced by steel....i was just thinking out loud i guess...

you post up a goofy picture and give us an idea of a device that already exsists.. you gotta expect some bit of flack

calculating hp is not just as easy as instantaneous change in velocity
sorry dude

turbo z24 guy

what....the ----... take it to the dyno! dont even try to make one. this is homemadeturbo, not homemadedyno

accordepicenter

umm for all the time and $ to make this a reality... damn just get a G-TECH... Its not ultra accurate but itll show when you get a performance gain, like before and after comparison... and you can get one for less than $50.
