Will there be a GT5 300MPH Club?
Ive recently got a 312mph run in the R390 race car. easy as pie, picture will be up soonish.

Did you miss the rules at the start? Here's the relevant bit for the hard of reading.
Do you have a picture to prove your speed?
And that should be Lotus.

Someone Please Help Me My SRT10 is getting just over 270mph. It's got 1032bhp on it, a body refresher plan on it (thought that'll help), just oil tuned it, Racing Exhaust, Weight Stage 3, all I can do to it. The Suspension is Racing Default, the Tranny is 25Auto and nothing else has changed (haven't messed with the final Drive). Can someone please give me a good setup for this, I want to reach the 300mph mark. What should I do with my car?

@ SVX
Oh!! SVX, it's a misunderstanding, BHP is Power, I take it you thought I meant speed?
Lol Yeah True though it would be impossible without a cheat device with Speed of that...
Anyway, Got any ideas on 300mph+?
Rotary junkie, you?

As long as it has the test track and a top speed mode (which is probably quite likely), then I'm fairly sure it will happen. The only other requirement is that we have a high level of flexibility in the car set-up. If they tone that down to just 'quick settings' then they'll be removing a big part of what makes this club so satisfying: the copetitive aspect at the top end.
All of this applies to Gran Turismo for the PSP as well (which is more likely to have a reduced flexibility in vehicle setup).
Of course, you can be sure that I'll be involved. I think it's somewhat expected of me.
Are you still working with the SRT-10? That car is extremely difficult to get past 300mph. You pretty much need to tweak every single setting, including adjusting each individual gear by hand and experimenting with suspension settings. From what I remember it just becomes an aerodynamic brick at about 295, making acceleration very hard past that point.
It's not a car I'd recommend people use if they are trying to get into the 300mph club for the first time.

Hello all,
This is my first post here
Could I please get some help with reaching the magical 300 mph mark:
I am using the Nissan R92CP (used car / black version)
Here is my set up:
Ballast 0
LSD initial 6
LSD acceleration 15
LSD deceleration 15
Transmission: Auto 25
Transmission: Final 3.500
Brake balance 9/9
Downforce 38/88
Spring rate 17.2 / 17.5
Height 55 / 55
Bounce 2/2
Rebound 2/2
Camber 2.0/1.5
Toe 0/-0.2
Stabiliser 4/3
Driving Aids:
ASM Oversteer: 0
ASM Understeer: 0
TCS: 4
NOS: 70
The R92CP has 1155 Horsepower and Stage 4 Turbo
The fastest I've reached is 291.49 mph -- I'm guessing that there is one simple setting to change in order to reach the 300 mph mark, but I just can't seem to get past 291 mph!
Any help or ideas would be greatly appreciated!
Cheers,
Rob.

Here's a little formula to help setup gear ratios. It's really important to set the ratio's and final independant of the auto setting as it just doesn't work as well.
This equation tells you the maximum speed attainable for any given gear ratio and final gear:
(60R * W) / (G * F) = V
where:
R = the RPM at which maximum torque is produced (in the Lotus Esprit its ~7600)
W = the wheel circumference - race wheels are 0.0012694 miles (don't ask how I worked that out!)
G = The gear ratio (for max total speed that will be your last gear)
F = The final gear
V = speed!
I don't have the RPM value for the R92 so i'll show you my values for the Lotus Esprit V8 i've done it in:
R = 7600
W = 0.0012694 (race wheels used)
G = 0.735
F = 2.555
(60 * 7600 * 0.0012694) / (0.735 * 2.555) = V
578.8464 / 1.877925 = 308.23723mph
I actually achieved 307.58 mph
Having set the last gear you then need to set all the gears leading up to it so that you reach each gear in the heart of the power band.
Other more experienced tuners will help you with the suspension settings etc.
Hope this helps,
Bud

Hi Bud,
Thanks very much for the info -- so, I should tweak the gear ratios independently of the Auto setting? I'll give that a shot tonight.
I'll definitely try it out that formula! May I ask how you worked it out? Is this a commonly-used formula that real-life racing teams use? There's no way I would have ever figured out something like that!

Rob.

I would imagine racing teams would use much more complex formulae that are more accurate but you never know! It just took a bit of mental gymnastics, you know that the gear and final ratios work together to produce a 'total' ratio at the wheels. We also know how fast the engine is turning the drive shaft, just need to translate that into a wheel speed and change that to mph from miles per minute.

Thanks for all the information --
Done! I reduced the downforce to the absolute minimum settings and I tweaked the gear ratios (the car is still a little bumpy and feels like it is going to take off, so I'll need to tweak the Toe settings some more)
Here's the result so far
I'm really pleased to have reached the 300 mph mark -- it has actually helped me learn a lot more about the settings and especially how to tweak the gear ratios and Scaff's two fantastic PDF's on tuning helped a lot as well!
Cheers,
Rob.
Set downforce to lowest possible.

BUMP FOR GREAT JUSTICE
It's great to see this great thread still in existence.
It's also great to see records are still being made & broken. Nice job guys.

HI Everyone. I'm just asking what car I should use first to reach the 300mp/h mark?
I've got a FGT, a Merc CLK-GTR, a XJ-R9, and i could but some other cars... Waht would the set up be as well?
Where you said "(60R × W) ÷ (G × F) = V. Where did you get the '60' from?
P.S. If you want to know the alt codes for '×' is Alt+0215 and for '÷' is Alt+0247.

7600 is the approximate engine RPM at max torque. RPM = revs per minute, to turn this into revs per hour multiply by 60. Then multiply this by the wheel circumference (in miles to give miles per hour). Finaly divide by the multiple of the gear ratios (or more accuratley multiply by the inverse) and hey presto
