05RollaXRS

It looks like a 3 car comparison test. Porsche GT2 RS, Lexus LFA and Nissan GTR. I am very nervous now since A LOT of people are following this on twitter and people will going to the dragstrip to watch the LFA drag race.

I have been following their twitter page and they strapped the LFA to the dyno this morning. They will be going to the Vegas dragstrip to drag race the Lexus LFA.

I wish they conducted tests on their own track where they do elevation corrects to the time as Vegas is 200 feet above sea level.

I reckon LFA dyno'ed at 480 - 485 wheel HP.

How much do you reckon these two cars dyno'ed at??

515 wheel HP to the wheels

That is nearly 590 - 600 HP to the crank considering FR layout has a minimal 17 - 25% drivetrain loss!!!

We've spent many an hour dyno-testing cars here at MD Automotive in Westminster, CA. High horsepower cars, muscle cars, modified cars, you name it. However, none of them are like this 552-horsepower, 354 lb-ft LFA.

This car is special, and it clues you in the moment you thumb the steering wheel-mounted 'Engine Start' button. There's a very rapid starter whine vreeee like a race car rather than the usual chunter chunter. Then the engine explodes to life with a whomp before instantly settling into a slightly busy idle, the timbre of which telegraphs that this is no ordinary 9000-rpm V10.

There's practically no inertia -- or so it seems -- to the LFA's 4.8-liter power plant. You touch the throttle, the revs soar instantly. You lift, they die. Instantly. Normal cars aren't like this. Normal cars have soft engine mounts, sluggish tip-in, obvious electronic throttle manipulation, delayed engine braking, lots of suck. Not this one. Again, special.





At 2000 rpm, there's not much going on. This thing would get walked by a Camry down here, and that's only a slight exaggeration.

Good thing there are seven thousand revs remaining with which to do something.

By the time the LFA hits 5000 rpm the hairs on your neck are standing at attention and the short-stroke ten-pot is just hitting its stride. The intake and exhaust notes commingle and cavort, producing a texture that is somehow more than simply an aural phenomenon. It's no longer making a sound, it is orchestrating a mechanical symphony.





The tach needle brushes past seven -- where most engines have long since checked out for the evening -- and the LFA is now reaching its torque peak of 346 lb-ft (as measured at the wheels). Its sound hardens, taking on a shriek.

Two thousand revs left. It's still charging towards the redline with barely-restrained enthusiasm. Still plenty more gravy in the decanter. At 8000 revs you wonder how it is possible that this is a street-legal production car engine.





9000 rpm. The engine has ceased being a mechanical device and is now an organism, absolutely shredding the air around it with its howl. Here it reaches its power peak of 514 horsepower. Bam! The LFA hits the rev limiter like a wall. You have tunnel vision and your jaw is slightly agape. Your brain is the consistency of oatmeal.

This engine is gobsmacking. There are engines with more power, more torque, sure. But there is nothing on the planet like this engine. Its output as measured at the wheels -- which is slighly ahead of expectations -- is secondary to the experience it delivers. Raise a glass and wish it well, dear readers, as the 171 examples of the LFA that will be sold stateside will house the only known examples of this scintillating V10. Shame that something so good is limited to so few.

Pretty awesome. I wish they'd take it to the scales too.

That is Porsche Carrera GT territory since the highest stock dyno of Carrera GT I have seen is 530 wheel HP SAE. That is on a RR layout, which has a lower drivetrain loss than FR cars.

Shocking!!!

gengar

Really surprising. 515hp is much higher than I'd expected.

I love watching the coolant temp gauge rising as the dyno goes on.

05RollaXRS

I wonder if Lexus quietly increased the output on the production cars in the wake of stiffer competition from other cars since the white pre-production prototype dyno'ed at 435 wheel HP 1 year ago by MotorTrend???

The highest SAE corrected dyno for Carrera GT I found was 530 wheel HP.

The highest SAE corrected dyno for 458 Italia I found was 455 wheel HP.

515 wheel HP from a N/A tiny 4.8 Liter V10 is just nuts!! No words to describe it. This tiny engine is so highly tuned and highly strung, it is a pure race motor.

Hopefully facts like this will silence some of the LFA critics regarding its performance nature parallel to its price. The LFA is right up there with the best of the exotics. The LFA did not take ten years to make for nothing. It shows in the engine.

Stormforge

wow and speechless! LFA FTW!

rogers2

The video is speechless, but the article is overhype. IMO
The car is definately a beauty.

I'm impressed, but I'm taking it with a grain of salt CONSIDERING that dynocharts can be all over the place with different units spitting different results.

Just that sound alone in the LFA makes it priced right for me. Incredible!

MR_F1

True, especially considering they are hand built. However, I'd think that this much of a difference would be fairly outside standard deviation no?

I don't want to get caught up in the hype either, and of course I'll temper my expectations till a few other owners take a trip to the dyno, but it's pretty hard not to be flabbergasted by what seems to a 4.8l engine spitting out around 600bhp. Makes me wonder if the N ring version will get an actual 10hp bump or if the bump will be on the spec sheet only.

I wish they'd get it to a scale
