Is it possible for someone to give me the correct gear ratio so that the Mclaren F1 can reach it's realistic top speed of 241 mph. In GT5 I can't get it over 220 mph.

I don't want to just increase over all gearing. I want it to be accurate to the real Mclaren F1.

If any one knows what gear ratio I should put please help me and post it here.

Thank you so much.
 
you could try these 3.23:1, 2.19:1, 1.71:1, 1.39:1, 1.16:1, 0.93:1, with a final drive of 2.37:1.
from http://en.wikipedia.org/wiki/McLaren_F1 > Gearbox and powertrain

edit:
just checked, these gear ratios match with the default GT5 gear ratios.

from wikipedia too:
Top speed
With rev limiter on: 231 mph (372 km/h)
With rev limiter removed: 243 mph (391 km/h)

Stock power? I'm pretty sure the lower top speed is due to inaccurate aerodynamic modeling rather than gear ratios. It's not hitting the rev limiter in 6th, is it?
 
Sorry for the double post.

It seems like oppositelock was right. No matter what gear ratios I try it stays at 215 mph. I'm going to try to lower the ride height and see what happens.
Also before the update I was able to reach 220 now the max is 215. Strange.
 
I lowered it by 10 mm and using full transmission kit I increased topspeed to 242 mph.

I managed to get 5mph more. But the car doesn't feel the same with suspension tuning. :(

The car probably didn't achieve its record top speed using an ordinary setup so I wouldn't worry too much about having to tweak the car in order to also match it. Setting up a car for max speed runs and setting up a car for ultimate track performance are two different things.
You can be pretty sure your average real-life F1 can't hit 241mph without some tweaks.
 
The 241 mph F1 run was done without side mirrors, which I've read can contribute up to 8% of a car's coefficient of drag. As previously said, the rev limiter was also removed.

To the OP, I'm not sure I understand what you're saying about lowering the car. Lowering it 10 mm added 27 mph (215->242), and then you added 5 mph on top of that somehow? That doesn't sound right

Strange how all the pictures from Driving Ambition that show the F1 at Ehra Lessein show it with wing mirrors.

Do you have proof that the mirrors were removed?
 
That's what I read somewhere many years ago. It's possible that was bad information, I don't have proof one way or the other. You're probably right.

I added 27 mph in the tuning menu and I lowered it by 10 mm. Then I took it for a test it reached a topspeed of 220 mph. That is 5 mph more than before which was 215 mph. These times were all tested on ssr7.
 
Wasn't the high speed run tests done by not the standard F1s, but the long nose or LM ones? Just a thought. To be quite honest top speed rarely impresses me, on road cars, that is. The F1 deserves far more attention for it's raw handling and character rather than some recorded number.

Ok, that makes more sense. Seems to conform to my flawed aero theory.

I'm not saying it didn't. I just haven't heard that one before, and Driving Ambition says the F1 they used that day was completely stock, whereas it's common knowledge they removed the rev limiter.
 
Few people know this but although the McLaren's differential (Final Gear) is indeed 2,37:1, it actually has another reduction that makes it effectively 2,89:1. Unfortunately, it isn't possible to adjust only through the FG. I posted gear ratios closer to the real ones on this thread. The other thing that is wrong on GT5 is the RPM limiter, so I always try change gears at 7500 RPM.
 
But that's the opposite of what I would want. The rev limiter of the McLaren F1 is actually at 7500 RPM but on GT5 even on stock form it can already reach 7800 I think.

You can also be "pretty sure" it could do better then 215mph. :sly:

Answer to OP - PD doesn't actually have a great physics model, nor do they model cars performance all that well either. Sad but true.

You're right. Only the rev limiter was removed. The car that beat the record without wing mirrors was the Jaguar XJ220.
