well i can say one thing, some like there things is small packages and some like it in big. but what they dont know is that the small packages carry one of the most durable engines in the world. the bugatti is overresearched, overengineerd, to much to play with, for example put a 800-900 HP GTR with all supporting circuit modification nex to a bugati veyron around a lap of say silverstone UK. id be a 100 % cetrain that the bugatti would shit in its pants kepping up. the car is as wide as some of the roads in my country, being a mechanical engineer myself i realy dont like that car, give me my self built 600HP car anyday, di dont need a factory telling me that i should pay $1 M for it.

there is a (modified) r33 gtr in a motor mag i have that clocked about 315kmh at avalon airport. beat a lambo which only got about 308kmh. but that took longer than 14 seconds to get it.

but it isn't that unreasonable to think it is possible. just look at the top fuel drag cars. they hit 400kmh in under 5 seconds, 100kmh in 1 second.

No they hit 520km/h in 4.5 sec

The

0-300 in under 14 secs has benn done by more than 1 GTR

And as for the Bugatti i cant wait till these things are 3 years old and falling apart-Bugatti built Quality is shite

This argument is dead. The Bugatti is a massive feat of engineering and an amazing car. It was purely a "can we do it?" type excercise - never meant to be marketed as a profitable production car.

The fact that they ONLY cost $2mill each (when estimated R&D costs of $5mill per car have been thrown around) is amazing.

The car is gorgeous, more practical than ANY 1000hp Skyline and passes emissions in some of the strictest nations on earth.

It wins. Period.

No they hit 520km/h in 4.5 sec

now that sounds more accurate, i also believe they hit 100MPH in under a second, not km/h. crazy sh!t

and yes it hink the bugatti is a feat of engineering. an everyday supercar?

Yep also its 100mph in around 1 sec

Basically when the fueller launches from a standing start ,by the time the rear wheels reach where the front wheels were its doing 100mph-so the lenght of the car which is 300 inchs its doing 100mph. And no bugatti driver will ever know what that feels like :(

And no bugatti driver will ever know what that feels like

but a bugatti won't also know what it feels like to rebuild the motor after 10 seconds of flat out use (burnout plus race).

and the 100kmh was for a funnycar, my bad. i used to have a poster (about 9 years ago) of a 300zx funny car that had the times on it. it was 0-100kmh in 1.1 seconds. thats the only fidure off the poster i remember.

Must of been an Alcohol funny car-cause the Nitro funny cars are nearly as quick as the Top Fuel rails

Yeah like to see Bugatti build an engine with 7500hp and not need constant rebuilding

Ill take the Fueller anyday for a 'real' adrenilin rush :/

Edited by gtr660hp

For the record, Top Fuellers cross the line at 300mph (483km/h) plus... from a standstill... in 4.5 seconds. They actually do 0-190 or 0-200 (can't remember exactly) in 0.9 sec, which is their 60ft time incidentally. Farkin amazing. I believe the Yanks are a bit quicker again thanks to heaps more exposure and sponsorship dollars and more money in the tracks, with trap speeds of 320mph+.

But yes, anyone who says that building something like the Veyron is anything short of a stunning feat of engineering has no idea what they are talking about.

Found this on the net, quite interesting re Top Fuel stuff

One dragster's 500-inch Hemi makes more horsepower then the first 8 rows at Daytona. Under full throttle, a dragster engine consumes 1 1/2 gallons of nitro per second, the same rate of fuel consumption as a fully loaded 747, but with 4times the energy volume.

The supercharger takes more power to drive then a stock hemi makes.

Even with nearly 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into nearly-solid form before ignition.

Cylinders run on the verge of hydraulic lock.

Dual magnetos apply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.

At stoichiometric (exact) 1.7:1 air/fuel mixture (for nitro), the flame front of nitro methane measures 7050 degrees F.

Nitro methane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gases.

Spark plug electrodes are totally consumed during a pass. After 1/2 way, the engine is dieseling from compression plus the glow of exhaust valves at1400 degrees F. The engine can only be shut down by cutting off it's fuel flow.

If spark momentarily fails early in the run, unburned nitro builds up in those cylinders and then explodes with a force that can blow cylinder heads off the block in pieces or blow the block in half.

Dragsters twist the crank (torsionally) so far (20 degrees in the big end of the track) that sometimes cam lobes are ground offset from front to rear to re-phase the valve timing somewhere closer to synchronization with the pistons.

To exceed 300mph in 4.5 seconds dragsters must accelerate at an average of over 4G's. But in reaching 200 mph well before 1/2 track, launch acceleration is closer to 8G's.

If all the equipment is paid off, the crew worked for free, and for once NOTHING BLOWS UP, each run costs $1000.00 per second.

Dragsters reach over 300 miles per hour before you have read this sentence. * Top Fuel Engines ONLY turn 540 revolutions from light to light!

The redline is actually quite high at 9500rpm.

To give you an idea of this acceleration, the current TF dragster elapsed time record is 4.477 seconds for the quarter mile. This means that you could be coming across the starting line in your average Lingenfelter powered "twin-turbo" Corvette at 200 mph (on a FLYING START) and the dragster would BEAT you to the finish line FROM A DEAD STOP in a quarter mile distance!

The Veyron isn't legal on australian roads, Yes, How stable do you think anything is at 400km/h 10cm off the ground, no neither can the veyron, driving anything with 1000hp+ isn't easy regardless of it's handling the veyron is no exception, Give me a 1/2 of the price of a veyron and I will build you a skyline based car that will out do one in every aspect

Yep. That's why I said nominally legal. At the very least, its left hand drive only option makes it non street legal. The Veyron is street legal in Europe. Will your 1000hp Skyline be? Will the engine be as flexible? Will it be as drivable around town as it is flat out?Will it meet European emissions tests?

And I think that its very possible for cars to be stable at 400km/hr and 10cm off the ground, if the aero and suspension is done correctly. It used to be improbable that cars could be stable at 200km/hr - most modern sports cars will do that easily.

Just because you don't think its possible doesn't mean its not so. Its possible you have a small mind.

And as for the Bugatti i cant wait till these things are 3 years old and falling apart-Bugatti built Quality is shite

Skoda build quality used to be shit too. As did Lamborghini's. That was until Volkswagen took over them, and enforced their quality control onto those companies. The Veyron is no different.

Brand name history mean almost nothing these days in terms of quality. These days you can expect your Ferrari to spend less time in the workshop than on the road (unheard of back in the 80's), and a Mercedes Benz is no longer built to outlast the pyramids.

did anyone see beyond tomoro last night? they had the konengsieg (spelling) on it. they are going for the speed record soon in their new car. and it is only $650,000. it did hold the speed record till the veyron came along.

although it set the record at 388kmh (maclaren was 387), even though the maclaren hit 391kmh on an unofficial run.

at speed i think both the veyron and the konengsieg would handle better than a skyline. it is not just to do with the suspension, but the aero of them. even if you ad big wings and that sort of thing they still won't have the aerodynamics of these cars.

there is a (modified) r33 gtr in a motor mag i have that clocked about 315kmh at avalon airport. beat a lambo which only got about 308kmh. but that took longer than 14 seconds to get it.

That'll be Tony's GTR - built by RacePace if I'm not mistaken...

Looking at the fastest accelerating list of cars -

12 - Ariel Atom 2 300 2.88secs 0-100

By far the best considering cost v/s bang - my colleague is the OZ distributor (www.openwheelers.co.nz)

**Shameless PLUG !!**

$100K for face contorting performance!!

I saw beyond tomorrow and the koenigsegg ccx is one crazy car.

it set the record of 388 on an oval which limited speed. that was with the ccr. they are attempting to beat bugatti's new record with the ccx. i think that is a tall ask. it is well down on power and torque (although i would put up with these deficiancies). it will need aero on it's side to win this battle.

to the genius on this forum who could build a better bugatti than bugatti do using the bugatti team and budget, i wish you luck and question why bugatti didn't source your expertise in the first place. would your input have been "just make it faster boys". No offence, just jokes. Basically I think bugatti did the best they did with a bunch of brainy engineers.

would your input have been "just make it faster boys".

Basically I think bugatti did the best they did with a bunch of brainy engineers.

Why not, it worked for Bernd Pischetsrieder.

As the CEO of Volkswagen, he told everyone the concept Veyron was going to have 1000hp and do 400km/hr.......which was news to the engineers who could not promise anything near that. When they did preliminary testing and realised that the shape was complete shit for aerodynamics and cooling, they were told to deal with it because Pischetsrieder loved the shape so much it wasn't getting changed.

I reckon the Bugatti / Volkswagen engineers did an awesome job considering the inherent flaws the marketing parasites (as usual) inflicted upon them.

Which means, of course, even a bodyshape as ungainly as a Skyline might be able to do 400km/hr with full stability if you throw enough money at it, and ignore the protests of the engineers.

    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
    • See if you can thermal epoxy a heatsink or two onto it?
    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
