Well I"m going to go ahead and post my Pescarolo speed for now to get on the list. Been trying a few road cars but no sleepers have stepped up yet. Hit 319mph today and took a photo. Used the Playstation Pescarolo C60 '04.

Ive tried cracking 300mph in a TVR Cerbera Speed Twelve today and I made it, by 0.07mph; I went faster (300.37mph) but my cameras battery died before I was able to take the photo. Ill put up the specs below, so if anyone wants to try it or suggest me a better setting then go ahead :) . I think this car can go much faster but Im not sure :indiff: Is this classified as a race car or road car? :scared: As for the gear ratios for R92CP I havent tried it yet but I will do it soon so stay tuned for (potentially) faster speeds



Settings:

Spring Rate: 16.0 Front 15.5 Back
Ride Height: 53mm Front 53mm Back
Shocks, Bound: 8 Front 8 Back
Shocks, Rebound: 8 Front 8 Back

Final Drive Ratio: 2.680
Auto: 25

Tires: R5 (Super-soft) Front + Back
TCS: 5
Downforce: 0 Front, 10 Back (lowest setting)
Nitrous: most powerful setting

Power rating: Supercharger (1036hp), 300.37mph top
Turbocharger (1010hp), less than 295mph
 
Cheers qsiguy, you're going up on the leaderboard now 👍

There's been a lot of debate about the Speed Twelve's classification, GT4_Rule, but all current speeds for it are labelled as Race Car, so this will be no exception :) Nice going, anyway. I'd be interested to see your settings! As it happens, you've just done exactly the same as goapoison :lol:

Yep, don't expect it to last too long ;)

I'll be trying my best to get that title back 👍

Just some, ah, friendly competition, right? :lol:

557.43Km/H!!!!! = 346.37MPH

:sly:
Don't mind that 'PWND by A'PEXi' thing, it was for a forum where I beaten the previous record with 61.31km/h.
(previous record on that site was 496.12km/h)

Isn't this gear supposed to have 320mph top speed? if it is then you may want to reduce the top speed to 310mph or 305mph. You can try to increase final drive or increase top gear. Or you can use my excel file.

You also may want to try some part wheelie trick (not all):
- high front low rear
- soft spring rate
- low front downforce high rear downforce

But I can't suggest in what order because I never experiment which part making the car faster or which part making the wheelie easier. I suspect the degree of both is different for each part.
 
I doubt that would work. The Cerbera Speed 12 has virtually no top end, as it has more than 1100 BHP by way of supercharger, and is the only car you can do it with. He simply geared it according to the torque curve.

I had to reduce the final drive to 2.680 because every time I raised it, it went slower. I tried 2.940, 2.965, 3.010, 2.745, 2.715, and it goes lower the higher the final drive ratio is. I think thats because I fitted it with a supercharger, which boosts the lower-mid range but drops the high range. I got smart and tried to keep the thing revving as low as possible while still accelerating. When I fitted it with the turbo, it went muuuuch slower all around. For example:

at the curve, supercharged Speed 12 went 250mph in 6th w/o nitrous.
at the curve, turbocharged Speed 12 went 239mph in 5th w/o nitrous (if I shifted into 6th I would lose even more speed)

I didnt tamper with the ratios for 6th gear though.

If I did that, wouldnt the front wheels come off which is a violation of the rules posted by DE?

Oh btw for the speed record APEXi_ you have to switch the units to mph in GT4, because we don't know what conversion factor GT4 uses - I got somewhere around 511km/h on my Minolta 88C-V (which equals around 319mph when multiplied with 1.6) but when I switched the units to mph in GT4 the numbers dropped to 317.91mph. So you probably have to take the photo again in mph (thats what I did) in the rankings menu.

Edit: just what Toronado said.

On a normal road car, no. With the exception of, say, the odd Nissan R-390, max rear downforce will not wheelie any road car. Not even the Cien or ZZ-II, which both have higher than normal amounts of downforce able to be acheived. On the TVR, yes. There is a particular suspension setting you can apply to the spring rate in relation to the anti-roll bars that you can mess with to cancel it out until around 309 MPH, when it starts to wheelie again, and then you have to start from scratch on the suspension until it stops. Doing so has gotten me to around 312 (not quite but very close) with my Speed 12. Perserverence. And don't write off the turbo so fast. It can get you to 300, albeit barely.
 
so Toronado, what youre saying is that maximizing the rear downforce will actually make the car go faster :confused:

and whats with the sping ratios? Hard isnt always good? :confused:

I'll pm you some sample settings rather close to my current set-up and let you be the final judge, but no, in my experienced-backed opinion hard spring rates are not often the good way to go at all (and are infact all that is holding a few cars away from 300 MPH), as I'm afraid I have to disagree with suchayo on that matter, much as I disagree with DE over the effects of tire compound.

Edit: While I'm here, I've recently found another race car that no one has thought of that does 300 MPH, but it is not as fast as it's road car would suggest (which did 285.71 MPH for me with only 630 BHP). I call it the "Imitation JGTC Car. With Foglights".

This is confusing, lowering final drive should make the top speed higher.
I don't know the power figure of this car, so this is only an example. If the power figure mountain is top at 5000, started to fall at 5400 rpm where the top rpm is 6500, I will arrange the 6th gear so the car will reach 315 at 6000rpm.

That's why I said only part of it, as I don't have experience on this, I can only assume. But my goal is to use setting that can help reach top speed as much as possible without making it wheelie. I think I should do more experiment on high speed first :).

Thank for the information :).
I figure that downforce has bigger speed improvement than spring rate (as 12 has the same 1000m time as 4), so I sacrifice spring rate. In GT2 spring rate hold down wheelie more than ride height. So, this is wrong :dopey:.
I think I will try with soft spring next, sacrifying downforce.
 
Well

Speed 12's peak w/supercharger is somewhere around 6000rpm. (not sure though) so I lowered the final drive ratio so that in 6th, I would end up at around 7000rpm after using up all nitrous. So I lowered it to 2.680. If I raised the ratio, then it would cause me to go slower, because the engine is off its peak so it wouldnt accelerate much anymore.

Hope this clears up some confusion.

Good choice, the Speed 12 was what I used for my 300mph+ run.

It is more than capable of going faster, my own run was 301.91mph, and the leaderboard currently has Toronado running the fastest Speed 12, with 304.95.

Its classed as a Racing car for the purposes of the leaderboard (which I must confess I don't agree with - the GT4 Speed 12 is the road car version, the British GT Championship Speed 12 actually ran with restrictors limiting the car to 660bhp and would be slower!!!!!! - but thats the way its classed).

Edit Speed 12 now up to 311.15mph - see below.

K, I'll do that ;)
Ill edit this post later on, when I got that done.

It's quite the same, it's even more :dunce: !

Whoa ho, seems I've managed to miss quite a lot in 24 hours! Thank you for covering those questions Toronado.

RX-7 LM Racer, eh Toronado? I admit I hadn't thought of it, seems it worked well for you though! Congrats :)

Welcome to the Club, Apexi. GT4_Rule was dead on with the explanation of the units (Thanks for that 👍 ) and you complied quickly :) That speed will take 16th place on the leaderboard, which I'll try to update tomorrow - time's getting ahead of me :scared:

I think I know the cause for that. With the Mazda RX-7 (and no doubt you noticed it with your Mazda), the MPH speedometer is off by about half a MPH, ahead. So, when it converts it from KM/H (which, being a Japanese game, is probably what it runs naturally) to MPH, it messes up by around a kilometer, and screws up the real time speedometer time. Alternatively, (and as GT4-Rule raised for me, possibly the true case), when you convert the time found at the results screen (or the screen we all have been going to take pictures of), from KM/H to MPH through the options screen, it is in fact that screen that is wrong because it converts it to a speed that is not actually correct (let's say it converts 482 to 300 MPH exactly, when it is actually 299.62 MPH [It really isn't, but for the sake of comparison, say it is]). This means that it is quite possible that the results screen is incorrect and the real-time speedometer is right.

Lets hope it's not :).

I try another car
Not so lucky with GT-One TS020, only 341.01mph with hard spring


A bit faster on Audi R8, 347.06mph with soft spring (thank for the info Toronado :) ).


Video, nice car and nice spark :lol:. Funny that body scratching as much as this do not slow the car down :confused:.
 
opendriver19a
That R8 speed does not look good to me, the front wheels come off the ground on the back straight. Try putting more front downforce (I forget what its called) on it
Click to expand...
At what game time ? I don't see wheel lifting when driving (rear view). I though lifting should only occured when almost reaching topspeed?


How can I get photomode with speed displayed?
And if I want to proof using video, what view is the best? and how?
