Nissan has Hard Time with Modified 2001 GT-Rs
Three Skyline GT-Rs represented Nissan at TI Circuit Aida, the cars belonging to NISMO and TEAM IMPUL. All three are modifications of the 2001 model. The 2002 GT-R and its V6 turbo power plant will not debut until sometime around mid-season. Driver pairs Erik Comas/Masami Kageyama, Michael Krumm/Satoshi Motoyama and Kazuyoshi Hoshino/Tetsuya Tanaka (Tanaka was absent from the sessions) seem to be having a hard time sizing up to the new models introduced by Honda and Toyota. "We are hoping to collect as many points as early on as possible," said Comas. "If things go well, we shouldn't be penalized by the weight handicaps that will go to the front runners early on this year."

The fastest lap in the GT-R group was put in by Krumm/Motoyama (1'27.369"). They were tenth quickest in the overall results.

Skyline GT-R to Gain V6 Turbo Mid-Season
Taking a stance different from the constructors mentioned above, Nissan has chosen to start the year racing with modified versions of the 2001 Skyline GT-R. The reason for this was made clear earlier with the announcement that the manufacturer will be introducing a new twin-turbo V6 engine for the car around mid-season. The new engine, referred to as the "VQ," is expected to be ready for Round 4 or 5.

Even so, Erik Comas proved that the NISMO engineers didn't waste any time during the off-season, lapping the circuit at Fuji Speedway in 1'23.9 (unofficial) on February 14-15 at the first testing of the 2002 cars. This is about a second quicker than the best time recorded for a GT-R at the end of last year.

Comas seemed satisfied with the car. "Chassis rigidity has improved. We were able to clock good lap times consistently with only adjustments to the aerodynamic setup."

Three Skyline GT-Rs will be entering the series, under the same team management as last year: Two cars by NISMO, with Erik Comas and Masami Kageyama driving the No.23 car and Michael Krumm and Satoshi Motoyama the No.22 car, and one car by TEAM IMPUL. Tetsuya Tanaka has joined up with Kazuyoshi Hoshino to drive the No.12 car, replacing last year's teammate, Motoyama.

wow...
the new VQ seems to be like Nissan's new baby

what new car did toyota bring in?
i thought there were no more supras being made

Strange... I wonder how closely related to the VQ30DETT it is...

I would have thought they'd stick with the RB... I mean it is a time tested and proven champion...:rolleyes:

I guess they think that they can get more out of it, and realistically the RB series is a bit outdated, dont get me wrong though, i agree with you gonthrax. But Nissan thinks its time to move on........

I think the main reason Nissan is introducing the new VQ is because they have started dropping down the field with last years car. They hope the new setup will bring them back to winning races

that's good
i love the skylines

Thats the reason I heard to. The poor GTRs were being left behind :(

JEEZZZ A lot of people in this forum seem to love the Skylines.

I don't realy care...

I want the McLaren or NSX to WIN :flash: :flash: :flash: !!!


isn't it --
"SPEED is nothing without control!!!!!


I guess it works both ways :bloated: :) ;)

no idea, but i always heard it as being "power is nothing without control", and thats what the Pirelli advert used in their Ronaldo commercial

the trick to a good engine is to get the full HP and torque available as low down in the rev range as possible, and to remain there until full revs. that is where the RB was lacking in the end. and hence why it got ripped out.

does a v6 gain or lose rpm as opposed to an L6? what about torque,what the power differences of a v6 and an L6.

I think the rb is still a good engine,If veilside could make 1400 hp from that engine,then I think it's a good engine :D :D :D

I heard of people putting rb's into old 240sx's,has anyone ever heard of this?

in this case i think the V6 is putting out more power and more torque lower down the range, hence why Nisaan replaced the RB.

The RB is probably the best under 3litre engine ever,and Nissan have pushed one up to 1600bhp in testing.Yes the RB is often transplanted,and i think there are people on here who have seen it done to 240sx's

The object is not to get hp and torque as low in rpm as possible.

Why do people think this?

The RB26DETT's torque peaks at about 4000rpms, wonderful. This doesnt mean anything except that you have 213hp at 4000. (Good for the climb, but hear out what it could have accomplished with that torque.)
After that, torque starts to trickle off. Thats the reason the Skyline only makes about 320hp up past 7000rpms (not that this isnt alot), but if it kept its VE high as it is at 4000 rpms, it would make about 400hp when it came towards 8000.

Torque is an ingredient of horsepower, it means nothing by itself.

Even jump off the line is horsepower. Having good torque means less rpms on engagement and less pounding on the clutch. Even a Civic would burn a torquey V6 off the line with a good clutch. Its still horsepower.

And if the object was torque and hp as low as possible in the rpm band, then the NSX would be the slowest car in the JGTC...
The Mugen/NSX powerplant is 500 ponies at 9000rpms. Thats not very low in the powerband.

And the factory C32B makes 225lb/ft of torque. But the key is this, the torque across the entire rpm band is at least 220. And we can thank Vtec for that. Even when the rpms climb to 8000, the torque stays strong, and THATS what the target is. Torque at rpms... rpms are a GOOD thing. (Ex: 800hp at 18,000rpms, 3.5L V10; Formula 1) It does not take any longer to hit the target hp in high rpms versus low rpms, as long as the hp to weight during the climb is good. If the NSX and Supra both do 45mph in first gear, that means that the NSX is at 8000rpms at the same time the Supra is at 6000. The NSX gained rpms faster, so it balances out.

Its hp to weight at respective rpms. I really didnt mean to write this much, but it really bothers me when ppl think this.

A drag race is hp to weight. There are alot of complexities within this, but that is what it is.

i thought hp was torque multiplied by rpm? i maybe be wrong but just wondering

Fast, that's part of it.

Also, I don't think torque is nothing by itself is a fair statment. It's still important when rating an engine for power. And I would say it as torque is a part of horsepower, but horsepower is dirived from torque. Without torque, there is no horsepower.

Ok, about the hp and torque bit, here's what i know:

Torque

1.00 lb-ft = 0.138 kg-m = 1.35 N-m
1.00 kg-m = 7.23 lb-ft. = 9.81 N-m
1.00 N-m = 0.102 kg-m = 0.737 lb-ft

Power

1.00 HP = 746 W
torque (lb-ft) = 5252 x hp / rpm
hp = rpm x torque (lb-ft) / 5252

and that's all i know.

it's funny that skyline is still using turbocharged engine (VQ30DETT),
while other GT500 cars like nsx, supra, mclaren etc. are not anymore.

isn't that odd?

i thought hp was torque multiplied by rpm? i maybe be wrong but just wondering

all horsepower is the measurement of torque over time.

look at a dyno sheet and u can notice that the HP and torque power bands are really different in many cases. But one thing is for sure, they are the same at a certain RPM, which i belive is 4200RPM (correct me if i'm wrong).

Why do you think this? I am only asking because well you couldn't be further from the truth, as a matter of fact you peak torque and peak hp vs rpms is as far out as they can get.

Factory standard peak torque is just on 5,360rpm and peak hp is 6,175hp. That is with an ecu that is very conservatively tuned. Below is a dyno plot from my car before my last round of tuning with some more modifications. You can see the peak torque is around the 4,700 rpm make and peak hp is 6,600 mark. 252kw (338hp) at the wheels. That translates to just over 420hp at the flywheel. The engine itself is still factory standard, that is with only pod filters, exhaust, and the factory ecu remapped. Since adding the new nearly twice the thickness of standard front mount we've been able to increase the ignition timing to 24 degs advanced without detination. Just by doing that it went up over 260kw at the wheels.

Now even with factory turbos which have a .46 A/R exhaust housing torque does not fall off after peak hp like you are saying. Weird aye. No not really in the bigger picture. As you can see all this talk of torque to hp relation begins to fall apart doesn't it. Also notice that nearly peak torque is achieved without hitting peak or even close to peak hp, yet holds pretty steady until you get up to over 6,000 rpms then begins to fall off due to the smallish A/R of the exhaust housing on the turbos and the smallish compressor side as well.

Peak hp is directly related to the ignition curve/turbo(s) size/cams/porting of the head.

sounds like the skylines should be kicking some BUTT in the
jgtc. GOOD BECAUSE I LIKE SKYLINES !!!! :iceslolan :biggrin: :evillol:

The VQ motor is aluminum block, making it much lighter than the RB. It actually weighs about as much as some 4-bangers.

Another reason for the switch was that the VQ was short enough to be mounted behind the front axle, making for better weight distribution and handling. The JGTC Skylines equipped with the VQs were effectively changed into "Front Midship" cars.

On top of that, the VQ was quite capable of making the same power as the RBs, since the GT500 class is limited to around 500hp anyway. In 3L form, the VQ also produced more torque than the RB26.

Basically, Nissan got less weight, better handling, and more torque by switching to the VQ, with no major disadvantages.

I see.. But what is this specific engine??Is it a VQ35DE?? or a VQ30DE?? what is it? the hp,tq?

I'm pretty sure it's a VQ30DET, since there was already a production one. I doubt that Nissan put a whole lot of money into it. They basically wanted to see what a production-level VQ could do. This also helps them get in some development time for the next GT-R, which is supposed to use a VQ as well.;) Smart idea. I don't know any hp or tq figures(gotta be somewhere around 500hp), but maybe we'll find out if one of those cars makes it into Gran Turismo 4 or something.

The R34 GT-R was retired this year, too. It went out with a bang though, taking the Team and Driver Championships. The new GT500 car will be a Fairlady Z. It is probably similar to the GT300 Fairlady already in use, but with a turbo.
