Hi Guys,
I am sure this has been asked before but what do you think is the best bike engine and why to put in a car?
I am looking at sprinting a BEC and need to know which one I can beat up the most?
depends on car and budget
Hayabusa engines are the usual choice as these are able to be modded further to produce big BHP figures (turbo's etc are often fitted). Also you
don't have to rely on rev's so much, unlike a lot of bike engines.
Bikes such as R1's and some other litre sports bikes rely on high rev's to get the power up, but with more weight than a bike, this will
feel almost like turbo lag i.e. not a lot will happen below around 5000 revs and then all hell breaks loose (which has its own amusement).
The ZX9R has a very good power spread, with no noticeable coming on cam. Mine will pull like a train, two up in 6th from 40mph.
However, if you are going to use it solely for sprinting, the power band is irreverent because the engine launch speed, around 8000rpm? will be well
above the cam transition point.
I think the limiting factor will be the gearbox reliability. I would look at what others are running in your chosen class.
Motorbike engine. In a car. What are you thinking?
Frankly a ridiculous idea.
On a more serious note.
Hayabusa if you have the cash. Because they are excellent in the first place and being so good means that all the after market parts are
available.
If there is a reason to stay below 1 litre (class regs?) then that discussion has been had before: cbr1000rr, zx10, gsxr1000 all proven to be able to
win stuff. Just choose your favourite japanese brand. Some come with slipper clutch which might make them more robust.
BSA Bantam?

It's more about torque than power output for me.
For instance, if you want max power and costs aren't a consideration, the BMW S1000RR is the way to go, but the torque isn't the best and
gearbox is made of chedderilium.
CBR1000RR seems a good option at the moment, though if I go back to a bike engine I'd be more than happy with another early R1 like I had in my
Indy - a little down on power against current units, but still about 150bhp, decent enough low down grunt and still very quick. It'd be cheaper
to buy (if I could find a low mileage example) and I don't think and extra 20 to 30bhp for a more modern unit would make me significantly quicker
for the extra cost over spending the difference on a heap of Trackdays and getting some time behind the wheel.
What you really need is the MTT streetfighter, 320hp at 52,000rpm as standard. Or upgrade to 420hp
MTT Turbine streetfighter
I think terry everall and tim nunn it's the cbr 1000rr and are both very very quick sprinters!
Hi. Has anyone tried a BMW s1000rr engine? I have 4 new ones, 2 of which have looms ecu etc and was thinking of using one for a hill climb car
project. Any thoughts?
The spare ones are open to sensible offers if anyone has a similar project.
