:lol: Only Camaro fans would see math and think conspiracy.

It is a fact... 469 of 505 is 7.5%


7.5% is about 4% lower than possible...


No conspiracy... and you don't need to be a mathematician to figure that out.


The z28 in that test is stronger than the OEM z28.

They Dyno between 435-450...



Unless of course you have an explaination. I would like to hear any theories or conspiracies as to how this is possible.

Or you could just color yourself gullible and believe it :lol:
you're onto something. trust me, i absolutely agree that there's something off about those z28 dyno numbers.

Either Motor Trend missed it or Motor Trend is in on it.


Either way it is incompetents and unworthy of my attention... other than closing the article down from every approachable angle.

When is this head to head being released? Does anyone know if they actually put the cars on a track this time?

I want to see this particular z28 lap Laguna and compare it to the last run.

Randy has already driven the Z/28, GT350 and GT350R head to head. He posted, with pictures, on his Facebook about it. Idk when it'll be released. I've always had a hard time trusting Motortrends articles...

Motortrend is probably trying to see who will be more... gracious... to them, Ford or GM. Once those negotiations are done, they'll release the comparo. This inst to say I think the results will be largely skewed, but likely manipulated in some form or fashion.

Ah yes, I do remember that picture... I don't know if it was Laguna or not... If Motor Trend had the track rented for just that, I guess there is nothing they could do...


The results are already skewed... Admittance of a 530+hp z28 into the H2H was a very bad idea. The GT350R is tailing the 911 GT3 at that track, Ford claims it can produce a similar lap too. Yet Motor Trend blames the GT350 for losing the 21hp advantage after the dyno. Why the accusations? The GT350 dyno'd right where it should have... How come Motor Trend had the time to run down the road for a dyno then back to Laguna for this comparison? I was under the impression both sets of cars followed a similar path AND, I do remember someone on C5/C6 talking about the SS being faster in the track... but nothing...

Something had to take place... when oh when have they ever displayed a disregard for a head to head track event? Hell, I even seen C5/C6 members celebrating some leaked info in which they believed it was the SS that barely pulled out a victory...


In one article they will point to the SS's superior PtW ratio. That's why the SS was soooooo much faster (marginally in most areas) than a fully loaded GTPP Premium :lol: Then in the next article, they let a Ringer slip by them, blame the power loss on the GT350 and say "it's sooooo close".

The 2014-'15 z28 is NOT close to a GT350R... not even in the same damn league... The z28, without any special treatment like this one, can handle a GT350TP BUT, the GT350TP can manage a z28 in some cases. The GT350R has about as much of a shot at the 911 GT3 as the GT350TP has at the z28... It can and does happen... but it doesn't happen a lot...

469 is 92.9% of 505, so that would be a 7.1% drivetrain loss.

Redline Motorsports' DYNO Mite dynoed 455whp on 93oct. Which is a 10% drivetrains loss, albeit its different than the Dynojet used on MTs test.

Instead of saying the Z28 has a "magical" power train, its a lot easier to believe the motor is under-rated or those were ringer cars.

Has anyone found any dyno sheets from actual Z28 owners?

There are no rules to what engine any of them use, and considering the weight of these cars and the fact that in racing these cars will be spending more time accelerating than anything else it makes more sense to use an engine with tons of power down low. These Ford engines are nice on paper, but in real world practical use where there are no restrictor plates you are going to be at a disadvantage.
Ford is very aware of what size engines GM likes to use and the fact that they are just now upping the displacement and only offering it in the special car is sad. Do you really expect your competitors to drop smaller engines in their cars to make you happy, or are you supposed to rise to their level? Look at what Ford did to compete with GMs trucks, the 5.0 is only there to make the guys who want a v8 happy, the eco boost in those trucks destroy the competition. You should be asking for more from Ford instead of expecting the competition to give less to their customers. I've never seen Vette guys crying about and making excuses for their engines compared to the Viper's 8.4 v10.

Just now upping the displacement? Ford has used large engines in the past... the 5.4L in the older model GT500s and then the 5.8L in 13-14. Plus they had a supercharger on it...

You can't underrate and engine... SAE needs to be within 1%....


Why is the z28 doing well on the dyno? Because Chevy tuned it up for the Head to Head. The z28 cannot hold a candle to the 350R. The GT350TP was developed to compete H2H with the z28.

November 25 will be the head to head reveal.:thumbsup:
I can't wait to see how well this Motor Trend Edition z28 does at a track nobody has ever run on. Here's an idea for Motor Trend... go out of business already...

469hp from 505 is 7.1% then, much worse than my 7.5% estimate :lol: ON 91 OCTANE!!!


Wooooooooo Hooooooooo!!!!!

Anyone that looks at that and says it's not hot probably owns one... Looks like the z28 experienced a 4-5% increase... What about K&N? No? All good then??? z28's dyno between 435 and 450rwhp... This particular LS7 had 26-34HP more than the OEM car. Wanna bet it is set up at least in the suggested settings AND, no mention of Caster ever...


Oh my!!! Look at the LT1 SS!!! It is also about 3-4% too high :lol:


If I were a car guy and I read car magazines... and I knew how to math... I would probably see this dramatic increase and wonder how...


That's all I want to know... How did it happen? Why didn't the professional drivers notice the increase? Why did they still publish the numbers?

If they published the numbers and honestly didn't know... Okay... but they also need to understand they shouldn't be testing cars anymore :(

It they did know, and I find it hard to believe they didn't challenge it, then I'm sorry, I can't invest anything in their results. It is piss poor reporting... tgePill delivers a better product then they do :rolleyes:


So... just keep that in mind... once the cars tested hot, test should have stopped...

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.

The only other party I've seen dyno the Z/28 was Hotrod Magazine. They got 438 RWHP.

http://www.hotrod.com/cars/new-car-reviews/1406-2014-camaro-z28-forces/
While I saw less than a 5whp difference when back to backing dynos, Mustangs typically read lower than Dynojets...
