Godzilla vs Super Snake!

Title says it all.



Enjoy and comment.

...until a new monster comes forth to challenge the mighty Godzilla.

How about MFT's Godzilla?

better yet, what about the Grim R34per?

So what happened to MotorTrend's yammering about "under-rated" GT-Rs? Have they finally given up? Maybe they have, considering that GT-R dyno'd at a mere 412 whp compared to over 600 whp for that insane Cobra...

Wonder what the outcome would have been if they put some Hoosiers on both cars? There's no way street meats would be able put that much torque through the rear tires of the Mustang cleanly enough to beat the GT-R in a drag...

Me too, I have a feeling though that the Snake would have put a hurting on Godzilla. But that's not the way it went down here so I guess that's all that matters. The Snake sure sounds better. The thing I don't care for about the Snake though, it's nothing you could not do with a Terminator and a Kenne Bell, or a GT-500 and a KB for much less money. I want to see Godzilla and the Terminator!

Damnit. Just cars. Here I was thinking it'd be Monster Trucks. Godzilla Vs Snake Bite.

I'll have to check again, but the magazine at work had a stock GT-R dyno out at almost 500 hp to the wheels I believe. They mentioned something about torque as well, but I don't recall. I'll dig through my locker and find the article tonight hopefully to see where all the sources come from and what was the method they used to dyno it.

Which magazine and which dyno?

The problem is... most magazine writers don't understand dynos... in fact, many dyno operators don't understand dynos, either, unless they've had firsthand experience of the variance between different models of dyno beforehand and know how different conditions, testing regimens and procedures affect dynos.

Again, a dyno is useless unless you have a point of comparison... and even, then, it is more suggestive than anything else. One dyno in isolation doesn't mean very much. Just ask the owner of the bone-stock, 200whp B16A (160 bhp) Civic.

I recall them saying that the GT-R had 507hp AT THE FLYWHEEL, not all four wheels. I'll search for the vid....

*four minutes later*

Found it.



It says it made 430.6hp & 425.3ft/lb of torque at the wheels and with a 15% drivetrain loss it would equal 506.6hp (so 507hp) & 500.4ft/lb. The supersnake video has the silver one making 412hp & 393ft/lb of torque. Looks like either:

A)The red GT-R was a really good one!!
B)The silver one was done on a wet Wednesday where the workers just slapped it all together!!
C)The dyno wasn't calibrated or set properly on one of those dynos.

It was in UMM magazine (sort of like Maxim, but made in Canada) so I don't give it much credit, although they may have stolen the whole article from another publication (which most likely happened). I know what you're saying about dyno mess ups, one person on another site has a stock G35 that dyno'd out at 300 hp to the wheels and now claims to have the fastest stock G35 on the planet.

Didn't get a chance to look last night, hopefully should have some time tonight if all goes smoothly.

Edmunds was quite critical of this MotorTrend article, and rightly so.

Firstly: Motortrend was getting numbers closer to 410 on their first set of runs, which were done in 4th gear... which is closest to 1:1 (dyno runs are most accurate when engine speed and road speed are equal... or least inaccurate, whichever way you want it).

So they moved to third gear. Which is stupid. I can tell you from firsthand experience that moving from fourth to third gear changes the numbers a lot, especially on a turbocharged car, which is more affected by the torque multiplication factor of the gears.

Secondly, and more importantly: Nissan claims a 10% drivetrain loss. But of course, Motor Trend completely ignored this factoid...even though it's written all over the technical brochures and press releases... so they assume a 15% drivetrain loss to get 500 bhp, when applying a 10% loss actually gives you around 477 bhp.

-

Dyno-ing the GT-R against the Super Snake shows what you'd basically expect... that if the Super Snake had a 15% drivetrain loss and the GT-R had a 10% drivetrain loss, they'd be bang on for their numbers... adjusting for the dyno in question... if anything, the Super Snake is slightly under-rated.

And... finally... Motor Trend admits they're idiots for assuming 15%...



485 bhp, after calculating for drivetrain losses as measured on the dyno. Not that I believe the dyno is 100% accurate (primarily because they use a sweep test, not a load test), and the extra torque is probably due to an overboost function... but it shows how wildly numbers can vary from dyno to dyno.
