Hayabusa locost
what kind of spec would this be?
0-60, 1/4mile, weight, power etc...
heard about turbo kits for this engine... is it worth doing?
first time building something this big!!

Turbo any bike engine, and you might as well foget about locost....
If its broke, fix it. If it aint broke, take it apart and find out how it works!

I'd heard that 0-60 it isn't much better than an R1 - probably 4s ish. Where it gains is above 60, so 1/4 mile times are likely to be
better. 1/4 miles for R1 BECs are often in the 12s.
Busas make circa 180 BHP but their capacity means that you get it at lower revs than, say a 2007 R1 with 180 BHP. You get more torque with the busa
too but it weighs a bit more.
It is a popular engine for BEC builders but they're not cheap and the cost of a dry sump adds to that.

what do you mean?  too much power? 
forgot to add... that the locost wont be used for track days (since there arent any tracks in malta), just 1/4mile once in a while.

was reading on here that you can have reverse gear with the bike gearbox. how is this done? from where can i find the parts needed?
also... would a prop shaft and diff from an escort mk1/2 be fine?
also... is there any convertor or something of the sort to connect the propshaft to the gearbox?
(sorry too many questions)

A Kawasaki ZX12R engine has similar power output to a Hayabusa, so 0-60 I expect would be around 4 seconds (although never been accurately timed), 1/4
mile would be approx 12.5 sec, weight depends a lot on your budget and spec for the build but expect it to be between 450kg and 520kg. Hayabusa has
about 175BHP and 102 lbs/ft, so should give you a power/weight of about 350bhp/tonne.
Turbo's are available but expensive. As to whether it's worth it or not....... only you can decide that.

Yep, if I recall correctly my mate's Megabusa ran was around 12.8s / 114mph on a runway 1/4 mile event, so probably 12.5 or so on decent tarmac.
My R1 Locost ran the same day at 12.98s / 110mph so not a lot in it, although his car is a bit heavier than mine.

thanks guys for that info.
what i meant with 'is a turbo is worth it or not?' was if the power gain and drive ability of the car are worth that money.
any answers to this question?
was reading on here that you can have reverse gear with the bike gearbox. how is this done? from where can i find the parts needed?
also... would a prop shaft and diff from an escort mk1/2 be fine?

Whether its worth it or not is entirely dependent on how much abuse you're prepared to give your wallet, but don't underestimate the cost,
a good busa turbo conversion will cost anything from £7-10k on top of the standard engine cost.
My mate I mentioned above has since turbo'd his Megabusa and it has been a lot of time, effort and money to get it right, have a look on his
website here for some pictures of his install.

You can either use a reverse box (from Quaife amongst others) that fits in the middle of the prop, or fabricate your own electric reverse system that
will drive a sprocket attached to the drivetrain somewhere. The former will cost you ~£800 if purchased new although reverse boxes do have reliability
issues and a lot of us no longer use them. The latter would cost you £2-400 in parts and fabrication costs with the advantage that when you're
going forward, the reverse mechanism is completely seperate from the drivetrain, so no losses or risk of failure.
quote:

Nope, it will be far too short. You could take it to somewhere like Bailey Morris and get it modified to suit, which will include putting in a centre
bearing making it into a 2 part prop so it can reach the required distance.

Yep, you can buy prop adapters for about £50 from most of the kit manufacturers like MK, Stuart Taylor etc.

Turbo or supercharger, both make the car unbelievably fast if you've come from road based cars.

Yep it certainly makes them very quick and if you get it right they feel just like a much bigger normally aspirated engine, very little lag and the
turbo spools up nice and early so doesnt really interfere once you're really on it.
Still bloody expensive though

Yeah bike turbos dont suffer with lag as bad as car engines as the primary reduction helps them spool faster and the gearbox is close ratio as well
keeping it on the boil

yet another question....
was talking to my dad about the idea of the hayabusa locost and he came up with this...
how do you connect the trottle and clutch to the pedal box? the breaks aren't a problem i guess since its something independent from the
engine right?

Depends on the age of the engine, condition an mileage! Also depends on shipping costs.
To give you some idea I paid £2250 for an 03 engine with 5k miles on it just under a year ago. No delivery costs in that price!

engine is an 03 with approx 2500miles. £200 shipping cost. so engine is £2400.... sound like a good price then ay?
to buy a complete hayabusa it would cost me over £5000 locally!!!! not that worth it i guess.

Make sure you get all the ancilliaries you need, loom, ecu, etc.
At 5k for the bike, no it's not worth it.

Buying off Ebay is a bit of a risk IMHO unless it's from a personally recommended source or they have a lot of good feedback for supplying bike
engines specifically.
Have a word with Malc at Yorkshire Engines (Username
yorkshire-engines on Locostbuilders), he seems to be
very competitive on price, very helpful and has supplied a lot of people on here (not myself) with engines. He'll supply everything you need for
a BEC conversion and you'll be getting it from a known source.
