Am I right in thinking that there are basically 2 camps here - those that want to mod the car as much as they can afford to get the most out of it, and those that think the car as stock is hardly worth tinkering with because it took so much development that any 'tinkering/modding' will probably lead to problems/changes which you wouldn't suspect/envisage/want ?

 

MY standpoint is probably somewhere in the middle of these exteme views.

 

Be interested to hear people's thoughts...

If we are talking 5000+hp Top Fuel dragsters, then no, they don't use auto gearboxes. They use a series of clutches, maybe 6 or so. Off the line, clutch 1 locks up, but can't cope with 5000hp on it's own so it slips a bit. This is good because it prevents wheels from spinning. Next, clutch 2 comes in as well as 1 and gives a bit more grip. Then clutch 3,2 and 1 are engaged. Repeat until all 6 clutches are locked up and you sail past the 1/4 mile in

 

I'm not sure any kind of motorsport uses automatic transmision. Far too much efficiency losses to be used in competition.

 

Actually, tell a lie, I saw an auto being used in competition once, I think it was in the finals of Scrapheap Challenge!! Buchered a Ford V6 engine if I remember LOL.

I think you'll find Formula 1 cars are semi-automatic...

How 'bout starting up the old Skyline vs. 300ZX debate ?

why not start a "who actually owns a 300zx tt and can supply pictures of one"

 

And im pretty sure an F1 gearbox is about as close to a road automatic as Ben Laadin is to giving George bush a blow job

 

And as for the RB26 hmmmm why are Nissan dropping the straight six design and going back to the v design?

F1 cars do not have a torque converter. This is an essential component in an auto gearbox.

 

Instead they have straight cut 7 speed sequential gearboxes, and a 5 plate carbon clutch. Basically much closer to a roadcar manual transmission than auto.

The semi-automatic part is the computer that decides that at 19,000rpm it will kill ignition, disengage the clutch, operate the actuators is the g/box, shift up a gear, engage clutch again and then 'switch on' ignition again. All in just a few thousandths of a second.

 

This system is called 'Flat Change'. All top motorsports use it. F1, WRC, BTCC, Sportscars, Prototypes, GP bikes, WSB ETC ETC.

 

Hope this helps.

Robert.

Timmy, scoops or FASTREDZ have seen my car;-)

 

I quoted the F1 cars because they have no clutch pedal like a manual or a gear change knob. They are somewhere between a manual and an auto, so when the guy said above that all competition cars are manuals, he is incorrect.

 

I'm guessing that Nissan chose the flat 6 for the skyline because the car was a rally car, ie. a different kind of car to a 300 and this would provide more room in the engine bay/make it easier to work on?

 

The Skyline was not a direct replacement for the 300ZX - that's why it didn't have a Z designation and why they have made the 350Z to carry on the lineage.

F1 cars and rally cars use a Semi Automatic or sequential gearbox.

It is not manual where you move a stick with phisically moves the the selector to the relivent gear. Semi Automatic/Sequential you press a button then the computer controls the gear selection.

Ferrari have used a full automatic gear box for one of the Grand Prix's.

As for the Skyline being a rally car. I have never seen one rallying. What championship is it in. Dont forget the Skyline has been going for nearly as long as the Z series and I think they have always been straight engines. The 300ZX was the first Z to be V6, they where all 6 straight before that.

Page 111 of the Enthusiast's Companion - "Motor sport has changed since the days when a car like the 240Z could give a good account of itself in professional racing and rallying and be used by amateurs for everything from sprints to autocross. Nissan's strategy today is to use different cars for different events - the IMSA and Group C prototypes for top-class racing; the 300ZX and 200SX for production-based events in the USA; the Skyline GT-R for saloon car racing, notably in Japan and Australia; and a new small four-wheel-drive saloon for international rallying from 1991"

 

The thing is. Sequential gearboxes have a clutch and a gear cluster. Now these may be controlled by actuators in the case of F1, but a roadcar manual gearbox have clutches and gear clusters too!!

 

F1 cars do not have torque converters they loose far to much power to be given any serious thought for racing.

yeesh so where does that say the skyline is a rally car?

And i wonder what the IMASA 300zx racing car used for a gearbox? oh yes they used a sequential manual box

And look at the tech section for f1

They use a manual gearbox and use automatic shifting. there is a disctint difference.

An f1 car still uses a clutch and different sets of gears where as an automatic uses planetery gearsets, so there is a huge difference.

 

 

 

OK a saloon car - but not a GT tourer like a 300ZX - hence 4WD and straight 6 engine and unsexy body curves.

 

Older Zeds were only straight six etc. due to cost or fit for purpose. V6 engines are better than straight 6, other things being equal.

 

Go to www.howstuffworks.com

 

Oh yeah, manuals are for poofs !! The technical differences are immaterial, it's the functionality. You can get a conversion on an auto to change the gears when you want, but the car still changes the gears NOT YOU, like in an F1 car. Yes, for ultimate performance, an autobox is not ideal, but for most road use I reckon it's better. The fast gear changes make up for transmission losses. It's cooler, letting the car do the work.

I wasn't quite right about V6 being the best...see this link

http://www.howstuffworks.com/question366.htm

 

Remeber tho' that most high performance sports cars use V6/810/12, so there must be good reasons for them.

well thats probably the only thing youve been right about yet lmao.

 

V engines are inherintly stronger, more compact than other designs, hence why they use v's in F1, CART, NHRA DRAG CARS ECT.

At the end of the day you can get a VG30 to make as much horespower as you can an RB26 but its not really a viable option, as the cost involved becomes to much.

Boost for boost a vg30 engine is more powerful than the skyline engine and the supra angine.

(and senna before you lose the teapot plot) im talking in stock form.

 

The skyline is a newer car and seeing that it has the tech bits supplied to it by Nissan already is why they are such good tuners cars.

at the end of the day Nissan GTP 300ZX won its class at LeMans in 94 - ask what the skyline managed at Le Mans to date ? answer - 0

Huh? Comon Warren if we are talking more compact then how can there be so much more room to work on the RB26 when compared to the VG30, there is heaps more room in a GT-R engine bay

 

Surely the stock RB26 and the stock VG30 make around 300 horses each

 

And the GT-R is NOT a newer car at all, both GT-R and 300zxTT rolled of the production line in 1989, being the series one 300zxTT and the Skyline GT-R BCNR32.

 

The Skyline GTR is a thoroughbred race car and the 300zx is a US Market Grand Tourer.

 

Both great cars though, I will defo get another 300zx, I really miss it, looks much nicer than the GT-R..

..hang on a minute lads... I got a great idea..

One advantage of the flat six is that it has a lower centre of gravity, which is in keeping with the Skyline's awesome handling due to 4WD/4WS. They are probably faster across country than ANY other car ever made !!

 

A 300ZX is a different kind of car with RWD, designed more for comfort and high top speeeds.

Flat Six? - 4 Wheel Drive? The skyline has Neither !

 

S'ok Nelson, I know whatcha mean bud, its just Im being pedantic

Straight six I mean. Not inline.

 

Some skylines are 4 wheel drive aren't they ?!!
