AWDA Monthly: May 2009

First off:
I am finished updating all of the gearboxes but the ones that I decided didn't need to be updated or the ones that I couldn't get the cars for at the moment. So a few days and a couple million Cr. later AWDA is back in business.

These cars have been updated:
Hyundai Coupe FX
Mitsubishi FTO GP V.R
Nissan Skyline Sedan 350GT-8

AWDA Monthly:
Now that school is out and I have more free time I've been getting more involved with AWDA. For example I've started writing little descriptive paragraphs to go along with the setups, and been focusing on cutting costs. At the same time I've grown tired of working on the photos like I used to. I don't take photos in photo mode and edit them anymore. It was a lot of work and it did produce some nice images, but I have better things to do with my time.

This month was dedicated to research on gearing, and next month is going to be dedicated to FWD tech--though we will still be releasing 3 RWD vehicles. Among other things I will now be posting news about AWDA monthly which will include updated setups. As always our new cars will stick to our motto "Not as fast as possible, as competeitive as possible." MFT tunes cars to be as fast as possible, but I enjoy the competition, not just the speed. Looks like AWDA has a good future in GT4 since GT5 is still being delayed.

Test Results (gearing)



What I'm making of this is just that each cars characteristics seem to affect which gearing will be fastest, and affect it by such a small amount it is almost negligible. I would have to believe that having a 5th or 6th gear with a 1:1 ratio would make for better top end acceleration, while having a diff with a 4:1 ratio would positively effect lower speed acceleration, and many times AWDA’s gearboxes are half way between. This means no 1:1 gear as is traditional, but it does mean a pretty even acceleration through the gears, and in some cases (hopefully most) provides the best times. I will probably adjust some of the gearboxes, though not all.

Ratio to Ratio

You’ll have to bear with me here as I try to figure something out about gearing. I wanted to redo all of my gear ratios, but it has turned into a mathematical and theoretical nightmare. Anything over a 1:1 ratio at the gearbox is said to negatively impact acceleration, and a closer ratio at the diff is said to also impact acceleration negatively. The problem is you can’t really have one without the other. For example if I were to use a 1700kg, 540hp, 322km/h car and make 5th gear 1:1 the final ratio would have to be 3.225:1. So suppose you consider that that differential ratio is too small, and will hurt acceleration, so you make 4th gear 1:1, now 5th gear will be about 0.785:1 and the diff. will be 4.150:1. So if you use that 4.1:1 diff. now 5th gear becomes an over gear, which is also supposed to negatively affect acceleration. Put the cars on a track and there is no difference what so ever in times. Which brings up the question, why does it matter? I honestly don’t know, just me striving for realism I suppose. What I’m doing is taking each car with the gearing I had previously made for it and running it to the rev limiter and then recording what speeds it reaches in those gears. With this information, and knowing the ratio I can use math to figure out the new settings I want. This number is only approximate, but it takes a lot of the guess work out of re-gearing. I built the equations up in excel so I only had to enter in numbers to get the approximate results. Yet now I'm trying to figure out if it is really worth it.

Here's kind of an example of how it works:


This is handy, but it still has not solved my problem. Why do manufactures use a 1:1 gear ratio anyway? I will probably only use this for new gear ratios and not change any more of the older ones.

(GT4) Subaru Legacy B4 (updated)

Subaru Legacy B4 2.0GT specB



Power: 349bhp

Parts:
Sports Exhaust
Racing Brakes
Turbo Stage 1

Close Transmission
Twin-plate Clutch
Semi-racing Flywheel
Carbon Driveshaft
FC Suspension
S3 Tires
VCD

Suspension:

Bound: 3/2
Rebound: 8/5
Camber: 2.5/2.0
Toe: 1/0
Stabilizers: 2/2

VCD: 25

Notes:
From the outside the only thing to tell you this car is special is the lowered body on the large gold BBS wheels, the slightly more distinct splitter, and the Spec B badges. But if appearances fool you the price tag wont. At 85,250 Cr. It is priced to compete with a BMW M3 and it has the performance to match it, mind you that 85,250 Cr. makes this one of the cheapest cars AWDA has built. Despite its family saloon car appearance and affordability (compared to the other cars we’ve made), a lot of consideration went into this vehicle. The plan was to have 400hp, but 350hp was much more practical from this 2L turbo engine. Then there’s the gearbox. The HKS gearbox runs 5,600 Cr. and limits the cars top speed down 30kph from the stock one. Acceleration is improved but as you can see for yourself from the graphs below the car is only 0.2 seconds faster from a standing start over one km. One thing that numbers never can tell us is the way a car feels, and AWDA is big on feel. Hence the HKS gearbox was selected for the fact that it gives the car the feel of extra grunt when running out of corners. To compare this vehicle to others in its class of sporty four-seater saloon cars, B-spec was sent out to record times of cars with similar design, those results are posted below (cars prices listed with the cost of oil change, sports soft tires, and new wheels added).

P.S.
Need a little more top speed? Use the stock gearbox, but do give the HKS gearbox a try.

Final Gear: 3.700

LSD:
Initial: 10
Acceleration: 28
Deceleration: 40

Notes:
By no means is the engine in this car in any way high tech, but that doesn’t stop every inch of this car from being super. This engine might not be the most impressive thing to come through the doors of Ford’s and Proto’s factory but it sounds like an orchestra of earthquakes, and you’ll realize when you put your foot down what matters isn’t the size of the engine, it is the near 355hp that will send this car past M3s. We originally wanted this engine to be supercharged to 460hp, quite like the Shelby GT500, but we realized that such a car was so fast it couldn’t compete with anything. It was too fast. To deal with this cars weight balance that resembles that of an old Porsche we practically lifted an LSD from the Porsche GT2, and played with the suspension until we made a vehicle that was wasn’t just drivable, but survivable. Of course in any car balanced like a Porsche you know what to look out for in handling. Hopefully we’ve transformed this car from axe murderer to gentle giant.

LSD:
Initial: 10
Acceleration: 30

Notes:
This car reminds me of a seventy-year-old man that never grew up. It is the sort of car that arrives wearing corduroy to the tune of Cities on Flame with Rock and then pulls your pants down and runs away, or would if he could run. So sure it isn’t the fastest car, but you’ll be holding on to your trousers whenever it is around. Even I thought I was joking when I decided to take this car for a drive, but really that was far from a fair attitude toward the old cat. Jaguars were revolutionary at one point in history, after all we had just invented the wheel and three days later Jaguar has the S-Type. The problem is that was the last time Jaguar made a new car. So this Jag is no M5, but it will put an E55 AMG in its place. The price tag isn’t the only thing rivals a Mercedes SL 600 (177.5k Cr.), the speed does too. This cars biggest problem is its looks. If they say the camera adds 10 pounds then this car must add 20 years. But let’s set aesthetics aside for a moment and talk some technical stuff. The 4.2L supercharged V8 now produces 540hp, and sounds wonderful doing it. And of course it still weighs in at 1800kg because no one is going to by a Jag for a stripped out racer. One thing that made this car manageable was the fact that Jaguar used double wishbone suspension all around. So if you feel like bringing the old tea and scones to a race buy this car and don’t forget your sweater vests.

6th: 0.825
Final Gear: 4.150

Notes:
I am a huge fan of the Lotus Elise so I figured I’d play with her sister car, this MR2. This car shares the 1.8L power plant with the Elise, but since it hasn’t been tuned to rev to 8,000+ RPM, this engine was the perfect candidate for a turbocharger. This MR2 is actually lighter than the original MR2, so this car is one of the few instances that a manufacture has made a car lighter than its predecessors. Yet lighter was not good enough for me. The newer car is too tame, too sane, and the chassis feels a bit well… indifferent. So AWDA gives you the new MkIII MR2 Turbo. This setup was all about making the car feel tauter, part of that was using a roll cadge to stiffen the chassis. Of course since this is a game I didn’t let cost be an issue, but I do try to keep the cars as affordable as possible. Just to top off the package, the car comes with Lotus Elise rims to keep things cool and light.
