Think ive found a bike up to the job of giving you a good race Andy.
This thing is mentalfair play to the rider tho... must take sum guts to go a bike like that.

The fairings of the Hayabusa were designed for aerodynamics too. TTS will fit a supercharger, exhaust and other minor tuning bits to it, so will produce 250 bhp at the rear tyre therefore will do a standing quarter in 8 sec. They didn't mention changing major engine parts.

I had done some work on the aero, such as smoothing off the underside with some of B+Q's best 1/4 ply

The rollers can't load the engine like it would be on the road, on a high hp turbo car once it comes on boost it just shoots forward, rollers hold it back regardless of torque and hence impose unrealistic loadings. If you tune to these confines you get a slower car.
I measure 70-130 in 3rd gear in 10mph increments, if it improves, the mod stays on

Andy.F

I think you will find it simply spends its time with a wheel in the air like the R1 in the vid above

Ever watched the drag bikes on TV ?. Not everybody accidently wheelies or falls off and remember the quarter times too.

Do some of you guys not know anything about Andy F's history, or Pavlo's (Zen Performance)? They are NOT backyard amateurs Their cars are hardly standard to say the least but the numbers are real.

I enjoy these bike vs cars debates but it's ultimately an invalid comparison. In standard road trim, a big bike with a good rider will mash any standard road car you're ever likely to meet, and under almost all circumstances.

But push it to the ultimate and no MotoGP bike could get anywhere near an F1 car, not even a tail-end Charlie

fatmanscooby what colour is your scooby?, it looked great in the picture a few pages ago.

So to summerise. From the factory a std bike is faster than a std car but the more money you spend the bigger the gap becomes, car ultimately being faster whether it be in a straight line or on a circuit

Andy.F

This is a nice one, production car V bike.

I think the only time the bike has a look in is when the car brake lights are on Check out the difference in acceleration out of a corner

thats the vid i was looking for.These dbates are kinda pointless and i think andys quote above sums it up.From the factory a std bike is faster than a std car but the more money you spend the bigger the gap becomes, car ultimately being faster whether it be in a straight line or on a circuit.But then someone always comes along with "but what about an enzo/r1/veyron/busa turbo/f1 car/moto gp bike/rocket powered sled etc" one of those things that nobody will ever agree on

Andy.F

I agree

[Davey]

At those speeds areodynamics is the main factor and the Subaru isnt exactly famous for low drag co-efficients...

Christ that made me laugh.

A second opinion ? Just ask some of the thousands of people that were there to see it for themselves.

Research your marque fella

Being a 500bhp scoob owner and a GSXR 1000 owner too i have a good perspective on this. The bike is quicker than the car on a straight. On the twisties the car would murder it.

£ for £ the bike wins everytime.

10 second 1/4 mile bike for £5K - plenty around look in autotrader.

10 second 1/4 mile scooby for £5k- if only it was that cheap!!!!

[Davey]

You are taking the results of one piece of timing gear.. How do you know the gear is accurate.. Would you trust a single R/R result over all others??? I'm more talking about the physics of the matter not what you saw a little LCD display tell you.. Think about it.

Does anyone know the DCE of an Impreza by any chance?

There are other subarus and Evos that run around 196-204mph top speed. My car is approx 10-15mph faster than them at the end of the 1/4m so it doesn't seem too far fetched that it tops out some 5-10mph higher.

This is going to be a slow and painful yet publicly humiliating death.

Andy please delay the kill for as long as possible to afford us mere scooby mortals some much needed entertainment at this time of year

Andy.F

Hoppy

A few years ago I seriously questioned the possibility of any Scoob ever cracking 200mph. Aerodynamics and all that. I was wrong, but at least I listened, looked and learned

BTW, since when have bikes had good aeros? They're rubbish to start with, and hopeless when the rider is hanging their fat **** off.

This will give you a run for your money Andy!!!

i'd almost agree and say who ever is willing to spend the most money in the pursuit of ultimate speed will win, the possibilities aren't endless but they aren't far off.

[Davey]

+10mph at 200mph equates to like an extra 200-300bhp... Air resitance up at those speeds is like trying to sprint through custard.

ZEN Performance

extra 100hp is more realistic based on 600hp getting to 200mph, which isn't far off.

Andy.F

Here are the calculated values for the scooby/evo assuming mph is proportional to the cube root of power.
This relates to the top speed achievable on a 1.3/1.4 mile runway, unlimited space may result in a higher figure.

Many of these figures are backed up with actual measured values at top speed days/ totb.

bhp mph
160 125
220 139
300 154
340 160
380 166
420 172
480 180
520 184
550 188
600 193
650 199
700 204
750 209
800 213
850 217
900 222

I might add that the 210mph was achieved a few years ago now and I've gained quite a few bhp and shed a few Kgs since then

Brun

So it's fair to assume that your car is pushing around 900?
Do you have any pics of your car as it stands now? The last time i saw you car it was going backwards at 130 at Elvington

Andy.F

lol, I don't know, you tell me

RCMS were dyno'd at 850bhp
Norris at 940bhp
RC developments at 1004bhp

and its quicker than all of them !

I'd estimate that way back then it was around 750bhp.

Pudders69

Scotland: Are you still there?

Yes you can make a Scooby R1 fast or faster, its costs lots and lots of money but it is possible.

Now off t buy a zzr1400 and nip in on big cc turbo's on the way home.

Brun: what you doing xmas eve....me is planning sum drinkin!!!!!!!!!!!!!!

Brun

Drinking as in Wetherby?

Pudders69

Brun

I'll have to speak to the boss as she thinks we are stopping in Harrogate - i'll get back to ya when i know

Pudders69

well basically fella we are spending NYE at her brothers as he is only back for a coupla days r&r, so xmas eve is my play time. Phil & Ali will probably be out but Phils Treatment has started to wipe him out a bit so they are likely to be out for a coupla hours.

Infact me women is only likley to be out for a few hours then its me, thee and a moji's....happy days.
