Sean, please don't be offended, i don't doubt that the car is awesomely quick, but to match a gsxr 1000 all the way to 155 in a 7 ????.
Tell you what bring it to York next year and do the 0-60 challenge, if you hand me a timing slip with a sub 3 sec 0-60 and a 1/4et of 10 secs, i might
just accept i'm wrong.

Apparently this monstrosity only has a drag coefficient of 0.19!
Aerodynamics make no sense to me anymore...

Well, according to an online quarter-mile calculator, a car with a weight (inc driver) of 600kgs and 220Hp at the wheels should see a time of around
10.6 seconds...

I see it has 140BHP and yet it can only do 118mph whereas a Caterham with 140BHP can do 125mph with a Cd of 0.62. Then again, the frontal area of the
Bionic must be 3 or 4 times that of the Caterham.

Also, bear in mind that "keeping with" is a very subjective term. I drive a SEAT Cupra R 225 at present and although it is much faster
than your typical family saloon, when you are doing 50/60mph it doesn't pull away instantly from another car which has maybe two thirds the
power. It does pull away mind and when you combine the faster acceleration with faster cornering and better braking it all adds up to a much faster
lap time on the track.
It is also often the case that the car/bike in front will not be pushing as hard as the one behind. Not so much the case in a drag race of course.
ps. Wouldn't you need to prep the bike's rear tyre in order to do a 10sec 1/4 mile? Surely a bike with a cold rear tyre would lose more
time on a 1/4 mile run than a car with cold tyres? I'm not a biker but I would expect it would take a lot of effort to maximise a bike's
1/4 mile performance - more so than a car.

Don't always believe what you read, in my experience real world times never match what the calculators say. Its all about putting the power
down, But hey, truthfully i would love to proved wrong.

I allways said that I would stay away from santapod and the likes, I know it will all end in tears because ill have to have the boost wound open to
about 26psi and ill get carried away.......when is it

Usually around May time, and believe me it's no santa pod, hillbilly racing kind of sums it up good fun tho, and those timing slips are
addictive. You should get at least a dozen runs, so no need to go mad with the boost, well not at first anyway Go on you know you want to In
all fairness you would stand a good chance of taking home the silverware.
I'll remind you nearer the time, no one from here ever turns up, which is a shame as it's a top day out.

I wasn't doubting it was possible, just that it would require rear tyre prep (as shown in your video) as well as a rubbered in track to get the
best times. A car would also benefit from a burnout beforehand but I would expect it not to be quite so crucial to a decent 1/4 mile time.
On the subject of video's, have you seen this one?

Hi Everybody,
Been reading this thread with much interest, i will stress right now that my knowledge and indeed understanding of aerodynamics is VERY limited
however it is common knowledge and rather obvious that something like a Fury is better than a 7 regarding air flow over and around the body. This is
the whole point of us buying the old Tiger Storm moulds so we can supply a "smoother" body for the Locost chassis.
as soon as we have a demo car completed it would be very interesting to test it alongside a standard 7 shaped Locost with similar engine and power to
compare acceleration and top speed.
FT.

I dont dispute, if you involve lots of corners the bike will always lose, especially to a 7.
But in a straight line dash to 155, my brass would still be on the bike.

Look forward to that one Chris, maybe arrange it to coincide with the 0-60 challenge? its usually a RWYB and 2NZ day as well, with the additional
bonus of getting a 0-60 time on your slips. Only downside is, being May the weather might not be 100%.
more than likely i'll be arranging another drag day up at york for everyone who's interested at sometime in 2007,

Sorry, been a bit slow. I reckon in the best tradition of TG, that that was a fix, coz Clarkson is a know twowheelophobe.
Tiff and crew did a similar thing with a bike and a load of cars from 7's to supercars, and a few in between (like Evo's and clones), and
none were as quick as the bike.
I don't doubt that a turbo bec is quick, but can it do 100 in under 6 secs, let alone 60 in under 3?
For next project, I'm going to aim for 80 mpg at 80mph

Simon,
I know where you are coming from and you may well be right. However, a bike tyre only puts down a fraction of the rubber that a car tyre puts down and
I don't think a bike can generate any sort of downforce so cornering and braking (and start line traction) must be less than that of a car
surely.
Where the bike is untoucheable is when you can let loose full power without flipping the bike and without losing grip. I'm guessing that to be
from around 60MPH upwards while in a straight line.
A typical track will have a mix of corners and straights and I would guess there are some tracks which would favour bikes and some which would favour
cars. Clarkson might just have chosen one to favour bikes to "prove his point."
When all is said and done you can probably only compare the "ultimate bike" to the "ultimate car" and I don't think many
would expect any sort of bike to beat an F1 car around any track!!
Cheers,
Craig.

Craig,
Don't forget the tyre compounds - I never managed more than 800 (yep hundred) miles from a set of tyres on my 'busa.
I go to Brighton Speed Trials every year (including a trip back to Brighton from our honeymoon in Dorset), and I've never seen a car
(apart from "The Old Fella" - Allard J2 seriously modified) come anywhere near the bikes.
Anyway off topic, how's your build coming on? You must be nearly done now

Simon,
Oh don't mention my build... I've just spent the entire day fixing (hopefully) a leaky bath. Had to remove it and reinstall it basically
with a generous dose of silicon all round. I also had to repair damage to my house roof after the storms a few days ago.
I've been off work since 22nd December and have spent precisely zero days on my car. I'm hoping to get peace to work on it this weekend.
As usual, not much left to do but the last few jobs seem to take forever don't they!!
Cheers for asking,
Craig.
