Turbo vs. naturally aspirated - Stock Nissan GTR vs. stock Porsche 991 GT3 roll on race

[Sticky]

Interesting race here between two cars that have six cylinder motors with the same displacement. The execution of those motors and the drivelines they are mated to are completely different. The Porsche 991 GT3 has 475 horsepower from its naturally aspirated and direct injected 3.8 liter flat-6 that revs to 9000 rpm.

The GT3 sends this power to the rear wheels through a PDK dual clutch transmission. It is definitely a top end screamer. The Nissan GTR on the other hand features a turbocharged 3.8 liter V6 without direct injection. This particular model has 550 horsepower stock making it likely a 2013 to 2015 model. Thanks to the turbos it has 463 lb-ft of torque which comfortably exceeds the Porsche 911 GT3's 325 lb-ft. The GTR has more power and more torque but it sends its output to all four wheels. It also weighs roughly 700 pounds more.

The GT3 hangs in quite well but up top the GTR pulls. It does not pull away from the GT3 like we saw an AMG GT S do though. The GT3 does an admirable job considering it is naturally aspirated but the GTR is the faster car stock for stock.

Good race. I wanted the GT3 to pull it out at the end. I'm impressed the GTR kept pulling as hard as it did.

The Gtr torque curve drops off at full throttle higher rpms whereas the gt3 does not, yet the Gtr beat it. The Gt3 sounds good , high revver, costs $$$, but it just does not have enough area under the curve to run with the Gtr. The loss would have been more drastic against a turbo s....

Even if you have a perfect looking high revving curve you can't fight physics. The GTR has more power and torque and simply more area under that curve despite not revving as high. It's not about straightline speed though anyway.

If the GT3 got a little bit of boost though...

That's the thing though too. I bet the GTR wouldn't have a hard time at all keeping up with the GT3 in bends either.

The GT3 is so much lighter and more responsive plus it has no heat soak issues. The GTR can only mask its weight by putting down torque to pull it out of corners to a certain degree.

Either way, the GT3 is the better car to drive and the superior driver's tool.

If this if that, this is a straight line race as are the majority here and the Gtr won, so would the 911 turbo s in the same scenario. As well, any car enthusiast knows about the GTR prowess around a race track.... It's no slouch.

Nobody is saying it's a slouch what is being stated is the GT3 has the track and driving experience in mind.

If you want the straightline, go for a Turbo S. It exists for that reason.

The GT3 is the connoisseurs choice.
