I remember 87 buick grand national was underated.
specifically gnx model was a sleeper.
more recent the 2011 mustang 5.0
rated at 412 hp at the crank yet pulls 395whp that would be less than 9% parasitic loss.
pulls a 1/4 within a .1 of the m3.
underating is smart your direct competition false numbers to play with.
I'd say the stang is around 450hp.
proboably for insurance reasons.

NOPE, we do have 330 hp on our car, on the coupe.
328 hp is for G37 Sedan.
The Seden and Coupe have different horse power.
Also, our car doesn't even exist in GT5 lol. They only have the Nissan Skyline 370GT in GT5 and not Infiniti G37 coupe.
check out the engine spec here:
Infiniti G - Wikipedia, the free encyclopedia

Nah our car is in GT5 as the skyline 370GT and the Infiniti 07 concept. Both reads 328 as the horsepower.

This is a joke, right?
First of all, they use a 15 to 20% drivetrain loss figure for BMW, but then then jump to 20 to 25% drivetrain loss for Infiniti? LOL
The truth is that drivetrain losses are significantly less than 20 to 25%. All they have to do is perform a coast-down test on the dyno to learn the true drivetrain losses. Using a more real-world figure of 15%, that puts the VQ right where it should be for its 330 HP rating.
So no, the VQ engine is not underrated.

When a car is underrated, some people like to say it's because of "insurance reasons". That may have been true back in the '60's, but not today. Insurance companies don't use HP ratings to determine insurance rates anymore. Today, most manufacturers slightly underrate their HP numbers simply to avoid lawsuits. So many people have access to dynos that it wouldn't take long for a lynch mob to develop once a few people posted dyno graphs on an Internet message forum. Car companies know this and will be very careful with their advertised HP rating. Just look at the the new 5.0L Mustang for example.

can you mention one car with NA v6 that can smoke our car in drag race??
(other than cayman S, maybe its because of light weight car, So 370Z may catch up with cayman S)
man forget about the myth ur friends are telling that our car is slow..its pretty fast for a "V6"
all we need is more torque not more HP..because we already got enough HP..
I, personally.. love my car.. I can smoke most of ur "430" HP cars

i disagree. you have no idea about the power of VHR dont you?

I totally agree with the recent statements about the VQ37VHR and its power output, I think it's spot on, no underrate. So I'm sitting here thinking about how many other manufacturers making similar NA displacement V6's and it's hard to find one with similar output. *Remember Nissan/Infinti is doing it without direct injection, imagine what the output would be with it!
Since it's Sunday after Xmas and I'm bored, I took some time to study all the recent manufacturer offerings for NA V6's (eliminated I-6, H-6, VR6) based on their site specs.
Available NA V6 with the highest output from each manufacturer:
Acura's 3.7 - 305hp
Audi 3.2 FSI- 270hp (they have to supercharge their 3.0 to get 300hp)
Buick 3.6 - 288hp
Cadillac 3.6 - 304hp
Chevy 3.6 - 312hp
Dodge/Chrysler/Jeep Pentastar 3.6 - 305hp
Ford 3.7 - 305hp
Honda 3.5 - 271hp
Hyundai 3.8 - 306hp
Kia 3.5 - 276hp
Lexus 3.5 - 306hp
Lotus 3.5 - 276hp
Mazda 3.7 - 273hp
Mercedes 3.5 - 300hp
Mitsubishi 3.8 - 265hp
Nissan/Infiniti 3.5 - 303hp
Porsche 3.6 300hp / 3.0 hybrid - site says 333hp for just the V6 w/o electric motor
Saab 3.0 - 265hp
Suzuki 4.0 *truck - 261hp
Toyota 3.5 - 270hp / 4.0 *truck - 270hp
Volvo 3.2 - 240hp
VW 3.6 - 283hp
I think that is a pretty complete list for comparison and remember the highest advertised output of the VQ37VHR is on the Nismo 370z - 350hp. Impressive.
