350R VS Z/28

[thePill]

Then you must be blown away by BMW.

F8X M3/4: 421whp (425bhp rating) = 0.05% drivetrain loss. AMAZING!
F10 M5: 527whp (575bhp rating) = 8.3% drivetrain loss.

...or they have underrated engines, which is pretty much common knowledge.


While I saw less than a 5whp difference when back to backing dynos, Mustangs typically read lower than Dynojets...

:lol:

The z28 is a Ringer, sorry you believe differently. A RWD vehicle simply has a difficult time crossing the 10-11% barrier.

Anything under 10% become very, very hard to do... even with CC wheels, Driveshaft and a Transaxle... The SS and z28 is no better.


So, the z28 dyno's between 435-450RWHP

FACT

...and the SS won't beat the C7 either... probably between 370-390...

The reason MT continues to duped people is because people like you fall for it. Go put MT on the grill about this... let's see what they say...

BMW does not SAE certify their motors though.

As for the z/28 dyno, typically thats true for Mustang Dynos, but they can be corrected. Also if you'll look at some C6 Dyno's most are around 430-440 RWHP. I would assume the C6 has the better drivetrain.

That doesn't matter to him...

He's trying to prove a z28 loses 7% to the wheels... :lol:


Nobody wants to to get into the reason an SS Dyno's better than a 460hp, Transaxle'd Corvette with huge equipment advantages...

I find it strange that the intense detective work comes to a halt when they get caught cheating....

Why are you so hung up on the dyno's? They can be EASILY manipulated to put out any number they want but the real results always show on the track.

Transaxled Corvette with "huge" equipment advantages?? Does the Corvette have some magical set up that the Camaro doesn't? Im rightly confused in that one. Isnt there still a transmission and rear end the power has to travel through? Are you saying that the torque tube is that special that it takes less power to spin than a drive shaft?




Its been fun reading this stuff.

EEC 80/1269 is not that different from SAE and does not justify whp equalling crank hp rating. A good read:

The Motor Trend z28 is a Hot Ringer...

Please stop being so gullible... everyone knows it is very, very difficult to get below 10% in any car. The z28 isn't anything special... 435-450RWHP, NOT 470...

I think we can all agree on that. Either the dyno was messed up, or the car was not stock. No question.

 

[Stuntman]

C6 Z06s make 430-450whp, but the Z28 has a different intake, a (better) Tri-Y header vs the C6s manifold, a different drivetrain, final drive ratio, rear brakes, wheels, etc... And makes 11lb-ft more torque than the C6 Z06.

Without more dynos of Z28s, its difficult to tell if MTs car was a ringer or typical of Z28s. You can't take the whp figures from a different platform with all of the above differences and assume that for the Z28. That's pretty ignorant.

 

[Nataphen]

FWIW, I've looked up several stock dynos of Z06s stock and just Airaid, no tune. There are quite a few sitting right around the 465hp/435tq range. I'm sure that K&N uses a happy dyno, so it figures that it would read on the high side anyway. Maybe it's not so far off of normal.

 

[Khell86]

Yeah but their are plenty of people stating that 445+ is on the high end of the dyno on the corvette forum. Typically 430ish is considered the norm. I would also assume that the Z06 has the more efficient drivetrain. It is what it is. We just need the H2H to come out.

 

[Nataphen]

Ok, this is what seems more out of line to me. I know I'm over analyzing, and in the grand scheme of things, who cares if MT is biased? They've been biased before, whether they admit it or not.

Ok, the torque figures from the dyno seem far above what they should be IMO. The Z28 put down 438wtq, the 350R put down 376wtq. That's a 62wtq difference. The flywheel ratings only show a 51 lbs./ft. difference in the Z28 and 350. That's a huge difference in rated torque and actual. Let's not kid ourselves and say that the Z28 has a more efficient drive line than the 350, or that it gained 20+ tq with 15,000 miles. That seems off to me. Take it for what it's worth.

Dyno does seem high, maybe just a generous read out.

MT has been biased before all depends on who is doing the reviewing. that is why the only opinion I will care about is Randy when he does the hot lap. He tells it like it is.

 

[5.0 435]

Agreed. Ford built a car that you don't have to justify spending that kind of money for. You can use it every day just like any other Mustang if you want. The Z28 is a $75,000 track Camaro that will beat you to death on a bumpy road and cost $10,000 for a brake service.

You forgot to mention it comes with it's own class action law suit that you can join.

It is really hard who to trust right now. According to that article the straightline acceleration is better than how the car handles around the course. Slower than a new regular vette but a little faster than an m4, which makes it slower than a z28 around that track? So confusing:shrug:
