Just came back from a blat up to Wellsford with a 600hp RX7, a 500hp RX7 and a 300hp S13. I managed to go at their sort of pace without too much difficulty although I think everyone was being pretty conservative. I had a passenger and I don't think the cars were as familiar with the road as I was. Didn't stand a chance on the straights although corner speed seemed quite similar. Still pretty good fun.
Lesson of the Day: 600hp doesn't help one bit when you're stuck behing a que of holiday traffic. Had to laugh when I overtook them all at once.:killingme :killingme
p.s. Anyone else notice the number of Police on SH16 today. I've never seen that many out there before.

Ha...was at my parents' place in Whangaparoa last night...was almost going to cut across to Kaukap's and blaze up to Wellsford and back...
Tend to recall another long weekend when they were all over the place though...so didn't...fine choice me :niceone:
I wouldn't mind riding with those RX-7's some time though. Would be interesting to see what a car like that can do.

An asain guy went into fast fours and turbo and paid in reds for a $29,000 blue rx-7. they went out the back to teach him how to drive, after 10mintues he still couldnt so they droped him off at his house with it. 1.5 hours later he rang up "car go up curb into fence".....
the moral of the story. Cars are gay.

yeah.. can't physically get more than 450 stock turbs (and that's after going past inefficiency of turbos) and piping etc so 600 is pushing it quite a bit with mods too... ported and shit fuck i'd hate to run a 600hp daily drive cage that's a jappa. Specially a rotang.. sorta like 2 strokes hehehe

My mate grant (ZZR 11) and I ran into what looked like a skyline club outing one sunday on SH 39 just north of Pirongia there were a few Godzilas mixed in amongst them.. When large road bikes meet sport car enthusiasts on a Sunday ride/drive one thing can lead to another and it got real exciting. The cars were onto us on the corners, the bikes held their own on the straight bits with better speed and acceleration. The bikes only gave the cars the learn because of the traffic holding the cars up.:blip:

Dunno where the figure comes from but the Car owes him over $85k. Gear box alone is worth more than my bike. He reckons it'll do a sub 11sec 1/4 mile when its finished. Seems like alot of money when you could get a faster bike for under 1/4 of that.

Hahaha I have this conversation with with car euthusiest mates whenever we get on the booze. They will rant on about how their wankwank done up car goes so fast, at which point I take great pleasure at informing them that their car is in fact shit and almost any bike will urinate on them at the lights. They then change tack and say its about looking cool instead of going fast, to which I must question why they drive a cardboard box with a rice spoiler... and it goes on from there. Point is-some people are just sore losers

I'll say! I gave up on hotting up cars when I figured out you could beat most of em off the mark with nothing more than a $2000 250cc, then make em look completely rediculous with a $10,000 (So cheaper than their boy racer wanker mobiles) stock gixer, fireblade or ninja.
You want real speed and to show the world you have balls then do it on 2 wheels. Theres more skill and thrill in piloting a big bike well than driving a car fast.

It's interesting to note how many people with xxxHP cars (and bikes) have never actually been within a hundred metres of a dyno. It's also worth noting how many 300hp cars grace the pages of NZ Performance Car (I think that's the name) on their dyno days... bugger all, most are around the 100kw level, and it's only the big 6 cylinders that seem to even get near 200kw at all.

Got flied lice?
Had a head to head ... no, head to void with a couple of cages who thought it fun to race up the rimatukas yesterday... It was all very exciting, they were using lots of revs, tonnes of exhaust noise, getting close up into the slip streams of the other cars on the road and even taking the racing lines (almost in to an oncoming cop car). They even managed to get passed me, and then gain another 2 cars on me.
I had already had my fun for the day, so I just sat whare i was anyway the road was damp, and I wanted to see their show. eventually I got tired of sitting in the queue and sauntered passed the lot of them. they tried to keep up, but despite apprearences not hard enough.
I did feel sorry for them though... not just because they are in a car but because they hadn't enough sense to find a decent road to play on. 4:30pm on the way back in to wellington after a long weekend is a tad to try and race on.

Im sure there are 400+ HP cars out on NZ roads, but the majority of people who own those cars, respect their cars. I used to enjoy cars that much, but then someone introduced motorbikes, which i had never thought about. :nya: while they are spending HUGE amounts of money on cars, bikes are cheaper and more exciting :yes: and hell i can't wait until i can

Even 1/20th.
Blackyoshi had an r33 godzilla with around 400+hp (4wd remember) or so that could give a fair amount of bikes a run for thier money.. last time I saw it was chasing a gixxer thou down a straight.. didn't get its arse handed to it much at all suprisingly.
But remember.. these are stock bikes guys. Mod a bike eg turbo bus/thou etc and you will be pretty much untouchable in a line by anything road legal with 4 wheels. Not including a somehow road legal jetcar ;)

Turbo'ed thou's have difficulty below 200km/h putting the power down though. Roll on from 120 might be different, but I'd be putting my money on a modified GTR against a turbo'ed bike from the lights.

Yeap very true, most serious drags cars vs bikes end up that way with the bike fucking off after 40m or so, but an extended swing arm busa.. :P Hehehe.
There is always something faster than whatever really.. seen a nos viper turbo go past a busa big time at around the 280 mark, but the bus got the viper off the line and all the way there by a big margin. Around then is where the drag coefficient of the bike comes into play and they slow down. (0.70ish vs 0.2-.3 for cars) If cars had same power/weight we'd be fucked without streamlined full cocoon shells and stuff.. I was thinking a movable high speed fairing would be pretty awesome - cocoons you at 200+. Just don't stack.

Good, someone else who knows about poor aerodynamics of bikes. I have seen similar numbers for bikes, the rider fucks up a lot of it as well. Anyone ever wondered why in motorcycling we get every measurement, power, torque, weight, braking distance, disc size, acceleration, top speed, etc from the manufacturers but not the drag coefficient?

well, a bike is ok-ish, until you stick the rider on top.
And what co-eff figure would you give?? A nicksta or someone else extremely small and light...
or a weasel co-eff?? :nya:

Okay time to get geeky. The airflow around a bike is pretty much going to be delaminar once it gets away from front bubble and fairings. So in order to overcome that you need a perfect fit for the rider and smooth skin to encase the rider in. If it is not a perfect teardrop or something similar with streamlining encasing the rider it is going to get alot of drag occuring at high speeds where the air suddenly breaks away from a surface. Profile, parasite and form drag from memory.
Weasel (if he were more sluglike and filled all the gaps AND NOT PROTRUDING out of fairings :lol: .. sorta does anyway) would be better depending on initial bike size actually. Nicksta would create a large flat surface where she does not occupy space and the airflow would get very very messed up.
But in reality this is the opposite.... as mouldable Weasel is, he ain't a perfect aerodynamic slug shape so nicksta gets the win by simply using the bikes aero to max affect.
High speed, automatically moving fairings like I suggested before would do the trick, too bad noone has ever designed a bike or a system like that as far as I know... mabey one day I'll pay some monkeys :innocent:
I'll explain this better to you at another time.. need some drawings actually.

Wow... $85k for 11sec 1/4 mile. That's...'impressive'...
By contrast a CBRR600RR for around $15k will do a 10.5sec 1/4 mile straight out of the box.
Hell of a lot more exciting ride too I'll wager.

Never. Not even a stock litre bike. There's perhaps a couple of cars that can get close to 3 secs 0 - 100, GTR's are too heavy for that initial lunge.
Even when Top Gear put some super light track day car against a CBR600, the Honda ate it over the initial 100 metres.

So a modified GTR that is capable of 10.2 1/4's on road legal tyres wouldn't beat a turbo'ed GSXR1000 off of the line? I don't think so Tim. You try (not that I have) launching a std wheelbase BIG power sportsbike hard from a standstill. I'd guess you'd be fighting wheelspin and wheelies too much to be able to beat a 4wd 10sec car.

You should try taking a seat in a well set up drift car, those things lose traction at over 100kph no problem.
My brother has his sylvia set up well and he can step his sideways on the motorway in 3rd at around 100kph.

Yeah most cars as you say.
A mate of mine has spent literally hundreds of thousands on his cars over the years and has had some very very rapid cars!. One being a GTI-R pulsar with 550HP.
I raced him on my old 1995 tigerblade from Maraetai through to Whitford then back up to the Pt View Drive roundabout......
I could pull away from him on the straights but he hardly had to back off the corners. Hate to say it but his little shopping trolley on steroids was fairly even with the blade on the open road...mindue though I am a nana rider :yes:

Where did it do 10.2? On a strip with a nice coating of sticky rubber, or at the lights with tar snakes, diesel/oil and other shit on the surface.
Have a look at a time slip for a car like that and I'll bet most of the 1/4 time is made in the last 200 - 400 yards.
In theory a grunty 4wd should eat a bike in the wet from the lights, but I've cleaned up a few now on a sad old Bandit.
As for the Cd figure, what model are you going to use for a standard rider, a Japanese racing sardine or a fat git like me, and will he be tucked in or sitting up?

Lou, I am not asking for bike plus rider cd factors, despite the influence a rider has on the final figure. What I am asking (and I thought you would have picked this up from my posts) is for cd factors for bikes. Sure it may have little bearing in the real world (rider influence) but seeing as we get every other figure thrown at us, why not bike specific cd factors?
We get power to weight figures with almost every bike, but that too has little bearing when comparing a 65kg rider on a K6 750 against a 120kg rider on a K6 1000.

Just as pointless as power to weight ratios really. I suspect that some naked bikes may have better Cd than a sportsbike when the rider's absent.
