350R VS Z/28

[bballr4567]

The Corvette uses a transaxle, a more efficient IRS and drivetrain AND, I assume most Dyno's are done with 93 octane.

The Camaro should lose between 14-15% to the wheels... not 11%...

Please tell me how the Corvette is more efficient IRS than the Camaro? I'd love to see a REAL explanation not this simple statement.

What mustangs were dyno'd on the same dyno as the Camaro? and link to the results?

they did not dyno same day.

That was the best driver's car competition, and it still beat out quite a few in that competition if I remember correctly.

The lightning lap, it was fine through.

Gotcha. I could not remember which one it was and didn't feel like looking it up

GM uses cylinder deactivation in order to avoid the gas $ penalty. The 6.2 is the smallest engine they can use. Anything smaller would cause a vibration problem in 4 cylinder mode. That's what I read about the C7 and camaro.

The new V6 in the trucks uses AFM as well and its a 4.3L. The 5.3L V8 in the trucks also uses AFM.

They use the 6.2 displacement because it offers the greatest performance without any hindrance of MPG.

Unless they employ force induction, GM has to use displacement to keep up with the little 5.2. It's sad how all these years GM has been having to fight 4.6's and 5.0's and 5.4's with all the displacement they use. That's not saying much for efficiency but as the guys said in the 70's there's no match for

The 5.3 engine doesn't use deactivation?

The driveshaft is significantly smaller in diameter, leading to lower rotating mass and higher efficiency. However, I believe the rear end has higher losses. I couldn't find any technical info besides an SAE study than was $72 bucks to read.

Also the SS with the manual does not come with AFM. And it will get the same MPG as the Mustang. The auto, however does use AFM, and it will get better MPG than the Mustang.

Technically called a torque tube but you are correct.

That is the ONLY difference in the drivetrain and the difference is very very small. The fact that thePill brings it up every time is disheartening but not unexpected.

It's clearly fake. Look at the other posts on that page.

Can't be Internet tells no lies LOL

He doesn't understand that and believes all dynos are apples:apples comparable. Let alone the same dyno (or track day) conducted at different timea of the day with differing ambient temps that affect the results in power or lap time.

All Dyno's are not created equal however, we have been blessed with GT, GT350 and GT350R runs done at the same time.

IF, there were an issue with the Dyno, the GT350 and GT350R would have laid down close to 500 to the wheels.

Same applies to the GT... the 15.5% it suffered on the same dyno the SS lost 11%. If the dyno was a happy dyno, it would be happy on both cars.

In other words, a 360RWHP GTPP Premium would have been closer to 400RWHP.



I get it... Dyno's vary slightly... key word being slightly...

The z28 Dyno's between 435-450RWHP... The LT1 Corvette is 390-405RWHP... The SS should be about 1-2% less than the C7 just on the equipment differences.

I haven't seen the articles where the stangs were dynode. Can you send the links?

The GT350 and GT350R dyno'd 467 and 471rwhp.

The Yellow, Fully Loaded GTPP Premium MT tested was around 360-ish.

They are out there somewhere...



...and it boggles my mind as to why someone is disputing numbers that doesn't have the numbers... or even did a search to see if they exist


Both Camaro's Chevy sent Motor Trend dyno'd about 4% higher than the usual examples of LS7/LT1 equipped cars do. Both the 2015 z28 and 2016 1SS dyno'd about 4% higher than usual (7% and 11%) which makes results from said source rather questionable.

Ok. How did the 2016 Camaro dunk higher than usual when it was the only one dyno'd........

This the X-Files now????

I did some google searching but didn't find the article where the GT was dynod on the same as the SS. It boggles my mind that you compare dyno numbers of different cars taken on different dynos in different years and conclude that the difference in output must mean the car is a ringer.
