A-spec Intermediate Level Race of Turbo Sports: Deep Forest Raceway

[TonyJZX]

Xbow would be easy. I did it in the Seven Fireblade... only 220hp and 200kg added ballast so i could slap on the upgrades.

I was kind of wondering why there weren't any RX-7 cars in any of the fields. I'm pretty sure it's because they're fantastic cars! Wow. Take a stock Spirit R - 466 PP on SH tires and try.

Just won in a stock 457 PP '00 RX-7 RS on SH tires against the CTR2. :tup:

I tried in the Spirit R for a couple of races, I messed up on the first one (1st corner, 2nd lap) and came in 4th. Raced better (not perfect) and came in second to the GT-R Black Edition by 0.594 as he blocked me on the last corner and I couldn't match his acceleration. It was a sprint to the finish line as the CTR2, GT-R SpecV '09 and CTR "Yellow Bird" had a bit more acceleration and I had to push it just stay ahead of them before the finish line. Might try it again but with SS tires.

 

[Delphion]

I've had pretty good times with heavier cars, for the most part lap times have been pretty similar. A few of my lighter cars have run low 1:13 laps, and a few heavier cars have run mid to high 1:13 laps so the times aren't far of for me. I think one of my Mercedes ran a 1:13.6. Every car I use is fully modified, but most cars have been pretty close in lap times. I run sport soft tires on everything.

The only heavy car I tried that felt pretty slow here was the bugatti.

Well, every car at 55PP can win, especially with proper tuning. But I'm all about stock, except for a few small things like wings and oil changes.
I won with the prize car and got close with the Jaguar XKR-S.

 

[dave2319]

I see. I don't have any cars like that in my garage.

 

[JohnBM01]

I finally got around to testing out my tuned Ferrari 288 GTO and F40. I feared the F40 would be too much for this track, and I was right. I mean "too much" as in this car's performance and capabilities being almost overkill for a track and Seasonal like Deep Forest. After spinning out in two different attempts with the F40, I eventually retired from the race. The GTO wasn't much a docile creature either, but I thought this car was better suited for this course than the F40, though the F40 had somewhat more disciplined driving dynamics. The 288 GTO is more like a wild dog you have to try and tame, but it can be tamed. I did only one race with the 288 GTO and won. This, after I suffered a spin on the first lap before reaching the backstretch.

Because I noted a Nissan GT-R usually in the Top 3 for this race, I decided to go get a[nother] GT-R to add to my collection. So I added the 2012 Nissan GT-R Black Edition to my lineup of cars. I'll see how this goes the next time I try and take on this Seasonal. If I win with this car, it will be the first front-engined car and first 4WD car I won this Seasonal with. My other winning cars were mid-engine, RWD cars.

 

[Ridox2JZGTE]

Used these 3 GTR build to win the race ( the R34 uses 350HP, while the R32 and R33 may need power up - install low range turbo to get 350+HP ), the cars were fitted with SM tire ( more than enough to win ).

Notes :


The BNR32 GTR VSpec II released in 1994 was the last changes made to the R32 GTR Skyline, made to commemorate the 4th consecutive Gr-A victories, the Vspec stands for Victory Spec. The previous Vspec ( version 1 ) was already an improvement to the original R32 GTR. A short summary of the changes :

V spec 1993.2.3
Sale at that time price: 5.26 million yen
Commemorating Gr-A 3 year successive victories, sale
* Total height +15 at 1,355mm
* Brembo Brake ( caliper and rotor )
Standard fitment of *BBS aluminum wheel
Tire size increase of *225/50-17 size
* Vehicle weight 1,500kg (increase of 20kg)

V spec II 1994.2.14
Sale at that time price: 5.29 million yen
Commemorating Gr-A 4 year successive victories, sale
Tire modification to larger width *245/45-17 size

Vspec II production number at 1,303 cars. The Vspec II has numerous mechanical changes compared to the stock R32. With 17in BBS wheels specially made for the car, wider 245 sticky tires, in addition to the 1st version of Vspec which include Brembo brakes, ATTESA-ETS PRO, Active LSD at the rear, lower suspension and stiffer damper tune. There has been reports of higher engine torque output.

The Vspec suspension spring rates of the real car 2.4kg/mm front and 2.7kg/mm rear. These values are too low in GT6, so I used the lowest at the front possible, and use the ratio to set the rear rate. The rate used are 3.83 / 4.31, with the damper tuned to provide fast response and good rotation on exit. The alternate damper is included with has softer rear damper to give different handling. Camber and toe also available in 2 set, one is the base and higher camber/toe is optional.

The car weight is 1500kg, with weight distribution using real life corner weights of Vspec II, at 59.4/40.6, this is the closest in GT6 can get with weight reduction stage 2 and 195kg ballast the front end. This should give the mild understeer traits of the real car and oversteer when pushed hard. Most R32 GTR has closer to 60/40 distribution, with R33 and R34 improving with less heavier front.

LSD is set in 2 way this time, with setup giving good amount of lock and low preload. An alternate LSD with 1.5 way arrangement also provided.

Tire base set is rear comfort medium and front comfort soft, while all around comfort soft is optional. I intentionally set the rear with comfort medium to give distinct handling characteristics of the real car, with oversteer tendency on the limit due to the different ATTESA-ETS PRO programming in the Vspec.

The R32 was mainly tested and tuned at Tsukuba and Apricot Hill. The real life record at Tsukuba was done in 1994, driven by Keiichi Tsuchiya, the R32 GTR Vspec II was capable of 1:06.77 lap time. The replica with High Camber suspension and 2 way LSD is capable of low 1:06s on CM/CS tire. While at Apricot Hill on Street Camber and 2 way LSD, CM/CS tire, 1:38s. Both replay has been included.

Notes :


This is a simple replica build of a stock BCNR33 GTR Vspec, the Vspec is the top of the range R33 GTR with stiffer suspension and A-LSD coupled with improved ATTESA-ETS PRO. In real life R33 GTR Vspec has been dynoed with reports of around 325HP/ 330PS at the engine. The power at 325HP is base spec with optional stock GT6 power as optional.

The Vspec suspension spring rates of the real car 4.00 kg/mm front and 5.00 kg/mm rear. The spring rate can be set in GT6, with damper and ARB tuned for slight oversteer. The stock factory alignment has been used for the base suspension. A higher camber setup is optional ( use the available camber range )

The car weight is 1540kg, with weight distribution using real life spec at 56/44, and both has been replicated. This should give the close to neutral balance of the real car and oversteer when pushed hard.

LSD is set in 2 way this time, with setup giving good amount of lock and low preload. An alternate LSD with 1.5 way arrangement also provided, the 1.5 way will give much more freedom in turn in under braking.

Tire base set is comfort soft with aim to set performance against real life Tsukuba lap record which are 1:05.88 in 1995 and 1:05.73 in 1997. These times were noted in the Best Motoring videos having R33 GTR Vspec with "race" setting. The Nissan or BM crew highly likely tuned the ATTESA-ETS PRO CPU, suspension, track alignment, better brake pads, but keep the engine on stock power. The lap time performance is closer to NSX S Zero in 1997, also in 1:05s.
In GT6, the time can achieved with comfort soft tire with near perfect lap just like the real life 1:05.73 lap did, perfection at the limit. The highlight was the Tsukuba last turn, with the R33 dive late in the middle line, seemingly going under for a split second, but race alignment and the ATTESA-ETS PRO allow the car to rotate with slight oversteer giving the driver ability to full throttle to finish line. This is the result optimized tune mentioned as 'Race' setting in BM.

The slower R33 GTR times that were done on totally stock R33 GTR were in 1:07-1:08s range, 1:07.09 and 1:08.59. This should be with comfort medium.

The R33 was mainly tested and tuned at Tsukuba. The replay of the lap at 1:05s has been included, the lap was done with 325HP spec to match the real lap acceleration/speed/RPM at braking entry and exit. Suspension uses base set and 2 way LSD.

Notes :


This is a simple replica build of a stock BNR34 GTR Vspec, particularly the N1 and Nur Edition R34 with the best evolution of RB26DETT engine capable of 350+PS in stock trim. The Vspec is the top of the range R34 GTR, in real life R34 GTR Vspec N1 and Nur has been dynoed with reports of around 345HP to 350HP ( 355 PS ) at the engine. I have included 3 spec, 350HP Nur, 345HP N1 ( Gr N ) and 336HP stock GT6.

The Vspec suspension spring rates of the real car 4.00 kg/mm front and 5.00 kg/mm rear. The spring rate can't be set in GT6, but can be very close, and I used the ratio as well, with damper and ARB tuned for neutral balance. The stock factory alignment has been used for the base suspension.

The car weight is 1560kg, with weight distribution using real life spec at 57/43, and both has been replicated. This should give the close to neutral balance of the real car and oversteer when pushed hard.

LSD is set in 2 way this time, with setup giving good amount of lock and low preload. An alternate LSD with 1.5 way arrangement also provided, the 1.5 way will give much more freedom in turn in under braking.

Tire base set is comfort soft with aim to set performance against real life Tsukuba lap record which is 1:04.57 driven by Keiichi Tsuchiya on a R34 GTR Vspec Nissan test car with LM mag wheel, race brake pad, some track tweaks and N1 spec engine which very likely have 350+PS.

In GT6, the time can achieved with comfort soft tire with near perfect lap just like the real life 1:04.57 lap did, perfection at the limit. While the factory stock R34 GTR Vpsec lap record is 1:05.32 driven The Professor Nakaya Akihiko, this can be achieved in GT6 with 336HP stock power.


The R34 was mainly tested and tuned at Tsukuba and Bathurst. The replay of the lap at 1:04s has been included, the lap was done with 350HP spec to match the real lap acceleration/speed/RPM at braking entry and exit. Suspension uses base set and 2 way LSD.

Lap times should be in the 1:24s on SM tire, better driver could get lower at 1:23s.

I really like the gtr here. So far I think I've run the best in the spec v out of all the gtrs.

 

[gotseth]

Tried the Jag XKR-S and the Aston V8 Vantage stock with SH tires. Too heavy and lumbering for my tastes on this track and best finish was 3rd or 4th with Jag. This one is all about the RUF.

I won with the Aston One-77 by 8+ sec using a @GhostRider65 tune. Then switched to his NSX LM and blew the field away

 

[JohnBM01]

Say WHAT? Aston Martin One-77 for THIS Seasonal? I'm sure you had to considerably tone down this car to ridiculous levels to make this happen. I have a One-77, but I didn't know this could be entered. I thought cars had to be either Turbo or Supercharged.

I am NOT going to try to tone down the One-77 just for this race. I will, however, try to give my 2012 Nissan GT-R Black Edition the non-PP adjustments to make it perform better. At 546PP or so and with horsepower well north of 500, this car doesn't need any horsepower, and Deep Forest is a handling track... not a power/speed track. So this should go pretty well for this car.

You can add a supercharger or turbo to some vehicles. That's how I used the gt40, vipers, and many other cars.

As far as heavy cars I was able to get the win in the audi a6 s4 or whatever the big audi premium wagon is. The vehicle is over 2000 kg, I installed sport soft tires and everything else was stock. I think I won by 3 or 4 seconds.

It can be equipped with a supercharger; but yes it is toned down quite a bit. 493hp at 1,374 lbs. and power limited to 55%. it's actually quite fun and not bad at all to get around the track!

 

[Racin510s]

I've used every car in my garage that this will let me enter. Most I have won with and others not so much fun. My go to car is a '02 RX7 Spirit R Type A. I too have bought many cars though I already had all the cars I wanted. It has been fun grinding this race especially in the RX7.

 

[dave2319]

Thought this was amusing win, I think the ai was Sunday driving for this race. 100% stock focus with no oil change on stock tires, I think it's 435pp
