Or maybe even an old M5 could be had for £25k?

Just looking at that sierra, doesnt 4x1000cc injectors on a 2150cc engine seem a bit much! lol

[[GSV]Trig]

Not really, I'm running 440's at about 280bhp lol
Dont think a big engined car would do it tbh unless it was very powerful and very light, too much weight in the thing..

[Rave]

fact is Rods car can hit 200mph in less than a mile n half so all of you ppl that are even gonna go down the turbo'd busa road can stop right there as you'd get your asses handed to you on a plate... lol

Don't be daft Trig. From his own site, his Sierra can do: "0-150 in 13.3sec".

A bog standard GSXR1000 or ZX-10R can do 0-140 in 10s or thereabouts. They top out at 180-ish, but a 400BHP turbo Busa can do 230 or more- and it'll accelerate a fair bit faster than a stock GSXR1000 too. That's not to say that the Sierra isn't impressive- of course it is- but a turbo Busa will make anything look silly- even I dare say a Veyron.

For reference, a Jack Valentine tuned Blackbird did 200MPH at Bruntingthorpe in the late 90s (covered in Performance Bikes). The strip at Brunters is only about 2 miles long, and that bike was naturally aspirated.

Edit: for all that, I really wouldn't fancy riding a turbo Busa in the wet, one handed and wearing a cardigan

It's all subjective to funds aswell. A lot cheaper to get a bike up to that speed, although a car will be ultimately faster than a bike, it's a momoth amount of engineering in comparison.

Still, sierra's not too shoddy for an engine with it's roots in the 70s.

weight doenst have such a bearing on top speed - the main thing is aerodynamics.. i've no idea what an xj would be like,b ut it is fairly low and sleek..

You're right- in fact weight has almost no bearing on ultimate top speed. However, weight (and hence acceleration) matters in Britain because we don't have any Bonneville-style 8 mile runs to build up speed. It doesn't matter what your car's ultimate top speed is if it can't reach it before it has to slam on the brakes for the end of the runway.

Of course, in the case of the bike there's a bit of a limit to how much power you can get down from a stand still. 3 less wheels butting power down and a tendancy to remove the rider.

A custom lengthened swingarm is your friend on a bike with 200+ BHP.... but everything is relative; I'm sure there are cars out there that are fast enough to take a turbo Busa. In all but the wettest conditions though, an 850BHP Sierra is not one of those cars. BTW, it looks like a 2wd Sapphire to me from the specs?

I sure didn't want to start a cars v. bikes argument here, I love both and understand the limitations of both. I just had to point out to Trig that in fact a turbo Busa would make the Sierra look slow. If further evidence is required, see the second Ghostrider video where Ghostrider overtakes the camera bike (which has 295KPH on the speedo) pulling a wheely and going quite a bit faster. Simply put, at 180mph that bike was still accelerating hard enough to keep the front wheel in the air.

Oh I wasn't on about this specific case. Yes, it's a 2WD sierra. I'd imagine the 4x4 gear would cost astronomical amounts to get working to that level.

I'm just saying a car overall has overall advantage, but probably costs a hell of a lot more to develop. The end result being real bikes are faster than real cars.

A good example being the BAR vs the F1 type bike (fireblade? I know it's not a drag bike, but the F1 car aint a drag car either). Once the F1 car hit a point it had effective downforce it was gone.

200mph is my long term project from the 200sx. I think it is attainable with a bit of aerodynamic work. Problem is - to get a fast car from being able to do 170mph in 1.5 miles to being able to do 200mph in 1.5 miles you pretty much need to double the power.

Luckily, my S14 has lower drag than any skyline, and 200mph skylines are ten a penny. The madtech S14 i am sure could do 200mph if it was set up for top speed rather than drag racing, it hits 150mph in 1/4 of a mile so i would hope it could find the extra 50mph in the other 1.25 miles

the 0-anything is always going to suffer due to it spinning the wheels, once rolling the bike aint gonna touch it...
Dig out the full stats on the bike n lets have a look..

to be fair, thats more to do with balence.. i find it hard to believe it could have pulled the front up at 180mph if he just yanked the throttle - he just did it much earlier and kept his weight back since - you can keep the front up whilst not accellerating, and even whilst braking if you're careful

Not something I'd want to try just incase you got the balance wrong...

Wheelspin at 185's a nice one tho lol...
