TURN 10 please fix the Nissan r91cp!

Havent seen a thread on this yet but since the majority of us seem to definitely notice that this is an issue it should be addressed. TURN10 the top end acceleration/ top speed and power output of the new Nissan R91cp is bad. Topping out at only 180mph is a far cry from real life. This car can push 220mph with about 800 stock horsepower. Even with restictors it tops just 200! The problem looks to lie in the downforce perhaps, so just like the Chip Ganassi Ford DP please consider this and patch this wonderful car!

Gearing depends on different races the car is competing in, so this top speed could in fact have been used for a certain race perhaps?

Its just weird as its the slowest in terms of top speed compared to the other group C cars in game.Maybe they used the GTP version.

The R91CP modeled is the Daytona 24 winning car, so it should be able to hit 200 MPH with ease. If it struggled to top 180 like the in-game version does, it wouldn’t even have been able to pass the GTO class cars on the banking.

I think the downforce is to blame, according to the tuning menu, the R91CP generates more downforce than the Lotus E23, which is ridiculous. No way a twenty-five year old GTP car has more downforce than a modern Formula One car. The gearing is fine, the power is adequate, it’s just it’s not enough to overcome the insane downforce levels Turn 10 have given the car.

I just hope Turn 10 sees all of the complaints and, like the Ford DP, puts out a quick patch to fix this car and make it the true beast it deserves to be.

Early 90’s GTP/ Group C cars made INSANE levels of downforce - large floors, huge diffusers, wide wings getting much cleaner flow than comes off an open-wheeler.

I haven’t looked at the values for the car in-game, but here’s some aero data on the car in “Sugo” spec, which would be a faiely high downforce setting.

And the nissan was far from the most downforce loaded car of '91. have a look at the numbers for the Jaguar XJR-14 in IMSA spec.

Never would have expected numbers that high, impressive. Still, even in that spec, judging from those stats anyways, the car was clearly capable of 200 MPH plus, so why the Forza 6 version struggles to get to 180 is still a mystery.

It can’t hit 200 even without the restrictors.

Yup truth be told a patch is desparately needed. even with the restrictors removed and the downforce adjusted at the lowest possible setting and the gearing set a bit longer, the car still struggles to pass 200mph. i was super excited when i saw the car and very buzzed and dissapointed when i saw the top speed. This really is a 220+ mph car and its such a shame for it not to be properly modelled. Please fix it Turn 10!!!

Sure it might be slow, but it currently has the best handling of all the Prototype cars. On tracks that are mostly corners, such as Lime Rock and Rio, it already has posted the top leaderboard times. Improving it’s speed will just make it more OP on those tracks than they are now.

Wouldn’t removing downforce to a more realistic level counter that tho? It’s a balance between speed and handling, and in this case a performance update would give it more realistic speed in substitution for handling

Yeah, reducing the downforce to more realistic levels would increase the top speed and acceleration, but at the same time would reduce cornering speeds, increase braking distances etc…

The only reason it handles so well is because it’s pushing downforce levels that put the E23 to shame, take those away and you have a more realistically depicted vehicle, not a more OP one.

3 tons of downforce? Sheesh lol

Yes. This need a fix ASAP T10. I think that the downforce is cutting the top speed too.

This was the only reason to purchase the dlc and in practice is useless against the other prototypes.

Thanks in advance.

Also it would be necessary fix the 996 GT1 porsche to belong to the prototype class joining its mates GTOne and Bmw LMR.

I agree. I was shocked when I see the top speed of the Nissan R91CP. This is the Daytona car but the XJR9 is also the Daytona version and it doesn’t have a poor top speed like the nissan. Also it’s a shame to see that in-game Porsche 911 GT1 has the performance of a GT while the real car was close to the Toyota GT-One. But I don’t think T10 will change that

I agree and for the Porsche 996 GT1 the car was 1 class lower than the lmp1 cars in Forza 4 as well. Probably some sort of licensing problem.

I remember the R92CP version destroying the straights back in GT4, even though this is a different year it definitely needs a fix, pronto. A beastly ride like this shouldn’t struggle to get to 180, it should blow right past it.

I too was very happy to finally see this car in the game, but was also disappointed when i drove it.

I believe this car is the one that ran in the 24 hours of Daytona in '92, which would explain the difference in performance compared to the base model seen in the Japanese Sports Championships.

I don’t know the exact specifics but this car was restricted on horsepower and had to pit a lot more than the other cars for it to be eligible for the race. So while it’s true the base model has around 800 BHP, the one in Forza (I believe) is the modified ‘GTP’ version with Daytona Specs.

I did get really excited at first because I thought we were finally going to get a unrestricted Nissan Group C Sports car in a Forza game and was a little disappointed we got this modified version.

But, oh well, it’s better than nothing and, God, does it look absolutely spectacular.

800 kg downforce on the rear is absolut unrealistic high. No suspension can take such forces over 24 hrs in a banked superspeedway. There is definitely a issue with the aero. The car is in le mans not competitive without air restrictions. Gtp or le mans version plays no role if you put the restrictions out. Even a upgraded DP Car is faster and in reality they would never ever been upgraded to a 998 level.
The point is if you can’t bring the car to the level to the other group c cars, then it’s useless to race that car.
Whe don’t discuss here if the standard pi is right, whe talking about that you can race that car in p class against the most other p class lm prototypes.

So do we think maybe it has something to do with the way that Forza removes the restrictors? Because it adds all the horsepower back to the car. Or is it maybe an issue with the downforce settings. I don’t understand why you can’t put race tyres on as well as remove the restrictors because it goes to X Class. The times are still a lot slower than the other P class cars with both these upgrades on.
