Well, all in all, i have to say that the car runs pretty good. It still needs some refinement but at least it go's up and down the road. My fiancee calls it the smile maker, it gets sooo much attention!!! Everyone just looks at the car a bit confused then I rev it up and all you can see is big ol' smiles.
The whole thing about it not having enough power is a non-issue. After I re-designed the clutch pedal for more travel you can just drive it around like a normal car. I havent beat on it yet, I wanted to make sure the owner of the car got to drive it first.
I decided to throw out that custom air intake and go with the stock airbox. I did this because the dyno tuner did'nt really like it, (he said it was just to big) and the guys on the Hayabusa forums wern't crazy about it either. I had to come up with a way to get cool air in the engine, I will let the pictures do the talking.
...soooo...the dyno guys said too big of an intake?
...will you post the #"s of the pull runs with both intakes?
...like always...an outstanding job of good old American ingenuity....
jetfuel...we don't race dynos....
Actually, the (dyno) guy has only looked at the car and just did a quick parking lot tune on it so we did'nt hurt the motor. I will post all of the dyno numbers as well as quarter mile times just as soon as I get them. I just wanted to get the car back to the owner A.S.A.P. so he could enjoy it a bit before the long Michigan winter hit.
You are a true-craftsman...very nice job. I love how you hid the engine in the fake-speaker box. Heck it would be even more stealth with fake-speaker grills on there too.
This is top-notch work from my pedestrian, non-mechanic eyes, but as a smart fan and R1-owner I am in love with the fusion of smart and motorcycle....all with a reverse gear and A/C!
How loud is it inside? I know there are all kinds of ways to lower the noise-level...though the engine is its own sweet music.
Mad props. If money were no object I'd be all over this.
Drive it like you stole it and you don't have to worry about low end torque. Launch at 7k rpm from every stoplight.
It's a BUSA engine from one of the fastest productions bikes in the world besides the ZX-12. It's gonna haul arse anywhere in the rev range...even pulling a smart. ;) I am sure low-end torque won't be an issue.
I ride a Yamaha R1 and it hauls and with less displacement than the Busa...so I am sure even a conservative take-off in a SmartBusa is gonna flatten your head pretty well against the headrest.
$17k seems kinda high for a car that only does 125mph but the quality looks worth it. The smartuki kit changes the whole rear subframe suspension, and disc breaks, they also have an option for a front subframe conversion. The car won't be as fast as you expect the tires are still 7" and the weight hasn't changed to much. hope to get some numbers on dyno and 1/4 mile times. if theres an option to change the top speed let me know.
Unless you're racing on a track I don't see where on Earth you're gonna do 125+ on public roads...and in a smart it seems like it would be a bad idea with such a short wheelbase and the tall body shape. I've regularly had to beat back tickets just for 80 on the freeway, and that's the speed of traffic!
0-80ish are all that matter in the U.S. as someone said...so true, though it's nice to have the 125 mph top-end for higher-speed passes or just to pass quickly rather than slowly.
For what it's worth, motorcycles like the Busa and ZX-12 are top-end limited to 186 mph but you'd never wanna do that on a public road either.
