I don't think you're disagreeing with me. I don't know of many cars that can run 56 seconds around Tsukuba so this is definitely impressive. However, a TON of tuners have had an NSX in their fleet and none have gone this fast (even the monster turbo cars, if I remember correctly). Why? Balance. It is not because the NSX isn't balanced but rather than when you are pushing the knife edge of control, you have to have a car that has it all, not just massive power or massive grip.

As you said, not many tuners (I used the word as loosely as you) have the expertise to achieve that balance at this level of speed. That's all I was getting at.

I do disagree with you on the cost to develop a car like this, though. You have one-off parts (probably multiple sets before they were happy with the overall performance) that take a fair chunk of money to manufacture. Aero parts all require molds and tooling costs, even if they saved money by doing one-time-use molds. Suspension components are straightforward but again, they're one-offs with custom valving and springs, I'm sure. Engine parts are probably the most straightforward, though tuning ITBs is never fun.

Also remember that the NSX is raced extensively in Japan (and has been for years) in the Super GT/JGTC series. Lots of potential expertise out there.

51 secs.

 

500 hp and race tires.

 

I love the sound of that NA engine.

 

That's a JGTC GT500 NSX. I don't keep up with those cars anymore but back when this occurred, JGTC cars were one step back from being silhouettes.

The only part of the car that is original is the cab from firewall to firewall. The engine configuration is different (mounted longitudinally), the frame fore and aft the cabin is tube frame, and it has inboard suspension (read: Formula 1 type suspension). In short, it's only a mere facsimile of the NSX.

The one really awesome part about the JGTC NSXs is that they were required to use the factory engine and they were stroked to 3.5 liters and made about 480 hp NA. They eventually abandoned this and went with a turbo setup which more closely achieved the 500 hp necessary to be competitive.

JGTC/ Super GT cars are badass and they are the fastest GT cars in the world. But they are not even remotely comparable to production cars.

The car this thread is based on is a real production car that is heavily tuned which makes it awesome in my opinion.

 

that's incredible..

 

wow all amazing

 

that sound is so sexy!!

 

without detailing it I can say the gt500 nsx's made more hp than 480.

The reason they moved to turbo engines was simply tq - the restrictors they use on the car mathematically speaking allows enough volume for 500hp

However there are ways to make more hp, but with a turbo you can have massive tq as well.

The gt500 cars are in no way a street car - everything from inboard suspension to the most advanced sequential gearbox to any kind of suspension geometry and weight bias.

That 51 second lap was a de restricted gt500 car.

This NSX is impressive because it's not a huge company it's just a guy whose serious.

The fastest all motor modern sports cars from ferrari are in the 1:07 range btw

 

Very impressive!
