The Truth about the Supra RZ.

[fbccars924]

There have been alot of speculation as to why the Supra RZ is so hard to tune and drive. A few of the reasons stated are....
-Improperly modeled engine
-Chasis improperly modeled
-Just all around wrongly modeled

The truth is if you think about it there arent any other I6 Twin Turbo cars in the game that are also FR drivetrain. I6 engines have much different power curves than similarly powered V8's and V6's or even I4 motors. The only other car in the game with a twin turbo I6 is the AWD GT-R so truly there isn't any cars to compare it to. (discuss please)

 

[motortrend]

I don't know but I really like how the supra feels in the game, it feels a little slow but then it kicks in and feels awesome. Plus, it's awesome to see a replay of it running against race cars and beating them.

 

[fbccars924]

I mean though if you think about it there are no cars to really compare it to as far as power and drivetrain. Also, you are quite right about out running full on racecars, the srt10 viper is just the same.

Tom's Chaser. GS300. SC300.

Thing is, it's got NOTHING to do with the power curve. The car very literally does not have the forward grip to not wheelspin.

 

[fbccars924]

I know those cars quite well and the just dont have the sheer torque and power of the Supra nor are they as light. and the GS300 has a v6 and an optional v8 not an I6 they are very different. Also the SC300 is a less powerful version of the same I6 motor. The Supra is also approxamately half the weight of the Chaser, GS and SC300.

 

[Dengar]

Just checked. The GS300 does have an I6, not a V6. The fact that it is hard to drive and tune is more a result of the chassis and suspension design which seem to be very acurately modeled as far as I understand.

 

[lildomplaya]

I used the Supra on GT4 ALOT & I didn't find anything wrong with it. In real life, high HP Supra's do deal with traction, even through 4th gear. Now if your talking about a serious grip race tune, I speak no longer.

 

[fbccars924]

Im talking about tuning the car in general

 

[peter_vod69]

Don't know what sort of crack you guys are on but the Supra was fine in GT4. My fully tuned Supra lapped about the same sort of time around the nurburgring as my fully tuned R34GTR.

The physics model in GT4 was off anyway...

 

[fbccars924]

Were you using driving aids?

 

[peter_vod69]

Nah - they are the first things I turn off!

 

[fbccars924]

What tires. I know if you give it full throttle too early it will spin through 6th gear.

 

[peter_vod69]

What tires. I know if you give it full throttle too early it will spin through 6th gear.

Depends on gearing, but yeah, you had to be deliberate with the throttle. I'm not saying my lap was super fast (about a 6:10 from my hazy memory) but it was by no means undriveable.

 

[fbccars924]

Not at all, Thats the reason I started this thread. I want people to know this car is driveable and tunable. If done right this car is very quick and can outrun nearly any car in the game on a track other than the test course. I ran a 6'14.xxx on the ring with my tuned Supra RZ. Mind you I'm not the greatest tuner and driver so the time i set with my tune can be made better. It just takes more throttle control than any other car in the game too.

 

[Rotary Junkie]

I know those cars quite well and the just dont have the sheer torque and power of the Supra nor are they as light.

Not fully tuned, no. Well, the SC300 is actually just as light as the Supra.

and the GS300 has a v6 and an optional v8 not an I6 they are very different.

Wrong as stated above.

Also the SC300 is a less powerful version of the same I6 motor. The Supra is also approxamately half the weight of the Chaser, GS and SC300.

SC300 is roughly the same car as the Supra albeit with a 1JZ instead of 2JZ, but both it and the Soarer make their torque even earlier. And half the weight? Holy crap, I didn't know Supras only weighed 780kg or so.

 

[fbccars924]

Ok If you look up the info the Supra weighs around 1600lbs where as the lightest of the cars you mentioned is around 3200lbs. Also the 1jz in the sc300 is a single turbo not Twin Turbo like the 2jz in the RZ.

 

[Tornado]

Ok If you look up the info the Supra weighs around 1600lbs where as the lightest of the cars you mentioned is around 3200lbs.

1998 Mark IV Toyota Supra Turbo: 3505lbs.
Linky.

Not even the the Mark I Celica Supra weighed anywhere near 1600 pounds. It seems quite likely to me that you read 1600kg as 1600lbs. And 1600kg is 3520 pounds.

The only other car in the game with a twin turbo I6 is the AWD GT-R so truly there isn't any cars to compare it to. (discuss please)

Lotus Carlton

* Top speed - +176 mph (283 km/h)
* Peak power - 377 hp (281 kW) @ 5200 rpm
* Acceleration - 0-60 mph (97 km/h) : 5.2 sec., 0-100 mph (160 km/h) : 11.5 sec.
* Peak torque - 419 lb·ft (568 N·m) @ 4200 rpm
* Engine displacement - 3615 cc
* Engine type - Twin turbocharged straight six-cylinder
* Configuration - Front-engined, rear-wheel drive
* Transmission - Six-speed ZF manual
* Weight - 3,666 lb (1,663 kg)
* Production - 950 units
* Price - £48,000

 

[fbccars924]

Ok so I read the weight wrong but still the sc300 doesnt have the output the Supra has.
Also, Carlton If I am not mistaken falls short on power as well at around 650hp as opposed to 800+hp in the Supra
Edit: at the moment I cannot seem to find the curb weight values of the Lexus GS

 

[Greycap]

SC300 is roughly the same car as the Supra albeit with a 1JZ instead of 2JZ

Yep, and as a result it suffers from the very same problems as the MkIV Supra. No longitudinal grip for accelerating and almost as little lateral grip for turning. The power curve plays a role in making the Supra even harder to handle as the power doesn't come on gradually but kicks in at low(ish) revs and begins falling off after that.

The funny thing is that the supposedly inferior MkIII handles every bit like one would expect despite being just as heavy and not that significantly less powerful. It also ends up being nearly as fast because it can actually put the power on the road.

I want people to know this car is driveable and tunable. If done right this car is very quick and can outrun nearly any car in the game on a track other than the test course.

Driveable, after a very large amount of throttle control, yes. Tunable, yes. To an extent. It'll end up being very quick, yes, mainly because it has more power than just about anything else on the road but it never reaches quite the lap times you'd expect from such power figures. I remember getting my version to 1'40,xxx on GVS after a moderate amount of work but its limits were coming very close by then. As a comparison, a 740 bhp Corvette did 1'38, a 1032 bhp Viper did 1'36, a 641 bhp RX-7 did 1'38, a 911 bhp GT-R did 1'37. You'd expect a 900+ bhp Supra to be right there among them but it isn't.

 

[fbccars924]

Now, mind you im not he best driver but my MKIV is smack in the middle of my best times on Trial Mtn. Being only around one second slower than your RX-7 tune bearing in mind that it was that close to a clean lap after a bad spin on the 8th turn. In a head to head race though I dont doubt the Supra would win

The GS300's is heavier at around 1600kg for the '91 version and around 1700kg for the '00 version and both their 2JZ's are different (the '00 is a vvt-i version). The X540, the SC300 and the Mk3 Supra are lighter than the Mk4 Supra but they all use the 1JZ rather than the 2JZ.

 

[Adamgp]

I've never had trouble with the Supra in GT4, even my 844hp S3 tired Supra.

The Supra in GT4 seems to be modeled correctly, the real Supra has trouble putting power to the ground too. They are dyno queens.

Reminds me of the joke that goes around the car forums:

"What's the difference between a 400hp Supra and a 1000hp Supra?"

".2 seconds in the 1/4 mile"

I've heard that joke a different way like this:

"What do a stock supra and a 1000hp Supra have in common??"
"They both do 14's down the 1/4 mile"
"What's the difference between them?"
"The 1000hp is doing 195mph at the traps!!"

Fixed!

 

[HashiriyaR32]

Hey, while we're on the topic of FR cars with turbocharged L6's, how does the FPV F6 Typhoon stack up?

 

[fbccars924]

I only recently found the Typhoon. I always thought it was a v8 until I tried it yesterday. It has some trouble putting power down but its no where near as bad as the Supra. The Supra hits peak torque and power low in the rpms and the typhoon peaks over a short period (~300-400 rpms) across the range rather late.

I've found the MKIV Supras actually handle great when power is lowish. Understeer is minimal, the car is very controllable, lots of traction, lots of grip, assuming the driver isn't a total novice who mashes the throttle all the time....so I'm assuming this discussion only applies to Supra RZs that have lots of power?

I actually haven't much experience (yet) with MkIVs that are highly-powered. But I do know they get quite fishtaily and difficult to throttle-up, which has been already highly discussed in this thread. I don't know about "improperly modeled". It seems to me PD put tires on this car that wouldn't be appropriate once it's highly-powered? Just guessing.

 

[fbccars924]

Very true. Even with R5's the mkIV will spin 2nd from a stand still. I have my gears all but maxed out and it still does it.

If you liked the Typhoon, try the FPV GT. Huge V8 in that one, tons of power. I ran that around Trial Mountain a dozen or so times, totally stock with S2 tyres, fastest lap was ~1'40.xxx. I even like the colour schemes...
