Dynojet 248C is actually an accelerometer whereby it uses a 3000-3200 pound drum that is used to create an inertia load on the vehicle being tested. The vehicle's horsepower (HP) and torque try to overcome the weight/inertia of the drum to accelerate it. As a result the software and electronics try to measure the horsepower and torque that the vehicle is developing to overcome the drum's weight and inertia. The resulting horsepower and torque will be higher than a true loading dyno because once the drum starts rolling not as much power is needed to keep it going. Example -- When pushing a car on a flat road, once the car starts moving not as much power (effort) is needed to keep it going. The software does not ask for vehicle weight or anything like horsepower needed to maintain 50 MPH (a number that is actually put out by E.P.A. and N.H.T.S.A.). The Mustang dyno is a true loading dyno, because it uses an inertia weight as well as an eddy current motor that is attached to the rollers. This eddy current motor creates a drag on the shaft by way of electricity that causes a magnetic field to try and overcome the torque going through the roller shafts. This current is controlled by software that is always trying to simulate load as if the car is driving in real world conditions. The real benefit from the loading dyno is the ability to maintain a load that allows a tuner to properly go through a fuel map or ignition map and tune the chip for optimum horsepower and torque. It has the ability to also simulate the IM240 emissions test as required in some states. It can check 1/4 mile times as well as times for 0-60 MPH and 0-100 MPH. It can also be used for road testing and simulation for drivability problems. As a result of the loading cap ability, the dyno numbers from a mustang dyno will come out lower than the inertia (dynojet) dyno.

until we see what can be done when the car gets here. With all the press we have been getting on Skylines over the years and the dirt their supporters have been tossing at the other countries sports cars we have yet to see a Skyline blow everyone off the track at Le Mans. I wouldn't expect them to send a LMP1 or LMP2 modified car but why not a GT Class car? All the big guns are there and there would be a chance to stick your finger in their eye? Even Aston Martin was there and after two years managed a win. Against a what some have called an easily out classed Vette? I will freely admit I have no clue how good the new Renault/Nissan might be but Renault has built race cars before. It is just that we always seem to get news of the new street king of racing coming over from Japan only to see it fall short of expectations year after year. Here is what we have been told over the last few years. Foreign press says the Skyline is coming to the US. We read in the car mags impressive prototype reports. We see examples at the Auto shows. We are tempted with hype from movies like the Fast and Furious and we get? We get the G-35, not fast and not furious. We were told at least two years in advance that Nissan was going to build a full sized truck that on Paper was going to take the US by storm. It would make us all forget about not only the F series Fords but the Toyota Tundra as well. On paper the Titan looked much better than it turned out to be as it failed to make projected sales the very first year. Nissan has made some reasonable vehicles. But they haven't proven to be the best bet in delivering a brand new car first shot out of the barrel. If this is coming over as a street racer,( as if we need another street racer?) then it will have to be easily modified. That is hard to do with such a complicated car. But the true test will be seen on the track and unlike Nissan who has a Porsche in the back ground as a test mule to build against I don't see Audi,BMW, Corvette, Porsche or Ferrari with any Nissans sitting in the background as examples of what a sports coupe or GT should be. Nissan will not get respect by sending out fliers they will have to earn it. I will try and control my enthusiasm for a Renault inspired Nissan designed super car till I see it leap tall buildings at my favorite race track running side by side with cars that have been attempting to leap those same building for years. I believe it wold be very foolish to get a totally new car manufactured but a company run by the person the industry calls "Le Cost Killer".

Replying to: boaz47 (Mar 17, 2008 12:39 pm) Their story is much like the GT-R story. Years Japan and Europe had these cars at their disposal, until we got them finally almost 10 years later in 2002. They were tried and true rally-bred street racecars. There really isn't anything that comes close for the coin you put into them. Even if they are ugly as sin this year. So lets not stereotype Japan as the nation that always disappoints. The GT-R was a huge flaming success in Europe in the 90's and early 00's. Stomping all over 911 turf. We finally get an updated version that we already know is based on a capable platform. They can test it in Japan, they can test it in Europe, they can test it in the US. But as far as a definitive race car goes, you are absolutely correct, that it is wiser to wait and see. we have yet to see a Skyline blow everyone off the track at Le Mans. I wouldn't expect them to send a LMP1 or LMP2 modified car but why not a GT Class car? The GT-R GT500 is already tearing up the Super-GT series. But that series is in the only region of its current release (Asia). I have little doubt there will be some either factory-backed or privateer versions used in American and European series racing, whenever they make it over here. http://www.autoblog.com/2008/03/17/supergt-nissan-gt-r-takes-first-and-second-in- -round-1-at-suzuka/

Replying to: bigmclargehuge (Mar 17, 2008 3:32 pm) You see those cars make my point. A few years ago I was a bit of a NOPI fan and even took a short subscription to sports compact car. I hear all the news about the coming of the mighty WRX and the Lancer EVO. Two thing happened that surprised me, yes as you say they were ugly but bang for he buck? On the street someone decided to make a Neon SRT and even sell a after market chip that turned the little econo box into a weekend money machine. People were bringing their WRXs believing the press and leaving the 1/8 import tracks with lighter wallets. Weight is the enemy even in AWD when you are on the street or in the only place you can get away with racing them in the daylight, the airport drag strips. But as I happened to mention this to a few I was told that they were much better racers in Europe as WRC cars and then I would see their true worth. So even though I thought WRC was like watching the grass grow I started following WRC. For the last three years the WRX Subaru has not been able to finish better than third in the manufacturers race by the end of the year. Yes Peugeot and Citroen were eating their lunch as was a little known car to me at the time something called a Ford Focus RS. Last year the Focus took the manufacturers championship with almost twice the points by year end as the WRX. The Lancer wasn't even in the running. I have stopped watching because it doesn't look like things will ever get better for Subaru in WRC. Maybe in some regional events but not the big leagues. I know you realize for a street car the aftermarket makes or breaks your credibility. The way things are you can get speed parts for a Ford, Porsche, Chevy, or BMW almost at your local 7/11. You can get Honda speed parts out of your breakfast cereal boxes. I know you can buy a cold air intake system for a Civic at Autozone. If Renault/Nissan wants to make their mark here it will be on the track against cars that are ready for them. It isn't often that a first year car is all that successful. Even the mighty GT40 took a while before it could hand Ferrari his hat for three or four years running before they decided not to play anymore. I will be looking forward to watching. I may have changed my interests to Rock Crawling and desert racing with some late Model Irwindale thrown in but I still follow ALMS and Import Sedan races so I should see some examples of this new super car that will run over Porsche and Vette alike before the end of the year? If not, you will buy the Beer? I am pretty close to Willow Spring, Buttonwillow, or Laguna Seca. |

Uh huh, and the valet will come back out and ask which Neon is yours.

Slapping an AWD system on a Sentra is no way to win my money. I have had the unpleasantness of owning a Nissan before. I had a 2005 Maxima that lived well below its expectations (oil leaks, stalling, warping rotors, rattles) so I don't have high expectations for anything else they have to offer. The Japanese are trying to buy there way into respected performance car territory. I didn't buy into the NSX (Accord), Supra (Tercel), or the 300ZX (Sentra) . I'm not buying into something that the valet is going to park at the back of the lot with the Hyundai's. I'll keep my 05 Twin Turbo Viper (0 - 60 in 3.2 sec) and dust off all of the wannabe's ricers in the Nissan. Another good 'ole boy making stuff up. The NSX had nothing in common with the Accord, nor does the GT-R have anything in common with the Sentra. Interisting how your quality benchmark is Dodge. Yechk. Funny how it takes a twin-turbo Viper to match the 0-60 time of a 480hp GT-R. Edmunds got a 3.3 second 0-60 time on their second try in the car. I don't think the 'wannabe ricers' are really going to be scared of a tractionless wonder like a Viper TT. Especially not on any road with curves in it. But as I happened to mention this to a few I was told that they were much better racers in Europe as WRC cars and then I would see their true worth. So even though I thought WRC was like watching the grass grow I started following WRC. For the last three years the WRX Subaru has not been able to finish better than third in the manufacturers race by the end of the year. Yes Peugeot and Citroen were eating their lunch as was a little known car to me at the time something called a Ford Focus RS. Last year the Focus took the manufacturers championship with almost twice the points by year end as the WRX. The Lancer wasn't even in the running. I have stopped watching because it doesn't look like things will ever get better for Subaru in WRC. Maybe in some regional events but not the big leagues. I can't help but compare your WRC cliffnotes to the Nurburgring comparisons. Rallying is very nearly all driver ability. Peugeot, Citroen and Ford dump millions into the competition, and have stolen a couple of drivers from Subaru WRC. So no, it probably won't get better anytime soon, but it has slightly less to do with the cars. Thats like saying Chevy is better than Toyota because they have more Nascar victories. Not totally relavent. I know you realize for a street car the aftermarket makes or breaks your credibility. The way things are you can get speed parts for a Ford, Porsche, Chevy, or BMW almost at your local 7/11. You can get Honda speed parts out of your breakfast cereal boxes. I know you can buy a cold air intake system for a Civic at Autozone. If Renault/Nissan wants to make their mark here it will be on the track against cars that are ready for them. It isn't often that a first year car is all that successful. Even the mighty GT40 took a while before it could hand Ferrari his hat for three or four years running before they decided not to play anymore. If you want a good drag racer, I'm not going to argue that the SRT-4 Neon was tough stuff. But add twisties to the mix, and its all EVO. With STI as a close second. Also keep in mind, that when they released the WRX in 2002 it was only allowed 225hp. In Japan it got 280hp. So yeah, they shafted us... until 2004, when it got 300. But the aftermarket on these cars is actually the easiest I've ever done. I see no point in buying a turbo'd Suby unless you plan on upping it to 350-400hp. Some friends are over 500hp. They still aren't great drag racers though. They don't have rear-bias AWD like the GT-R. Symmetrical AWD is stuttery on launches. But the aftermarket for these cars improves their track-ability at least as much as Ford, Honda or BMW. You might want to watch the Koni Challenge if you are so close to those tracks. The Subaru Legacy Spec-B has only entered 6 of 12 races last year and scored 2 victories. I don't know how many races they will enter this season. Can't predict end-of-the-year. I'm not even sure what month they are planning on releasing the GT-R. If it does fail to win a race its first season, I'll have to send you the beer via FedEx. |
