Auto ZHP faster than Manual?

[az3579]

Sean, what' you are experiencing is the kick-down. When you are WOT, the throttle position is at 80%, only when you engage the kick-down does the throttle engage 100%. This isn't exclusive to automatics, though.

I'm pretty sure it is... only the automatics have the kick-down switch. Manuals do not...

Wasn't this just a simple discussion point....ZHP vs. ZHP...one auto (with its diff) and one manual?

Not an accurate comparison. You just as well be a better driver in reality, with higher exit speeds.
Even if you two lined up side by side and launched at the same time, it's still not an accurate comparison due to reaction time differences and the like. The difference, if there even really is one, is negligible.

Personally, I say "no" to the auto being faster from a standstill. You can launch a manual as you please. An auto is sluggish off the line. Once the auto gets going it's fine, but that launch is the advantage the manual has.

From a roll, well, who knows. As I said, negligible.

BP, I totally agree with you. This was far from a scientific test, and was just my observations at the track. As you noted (and I should've specified) there are way, way too many variables in play to call this as accurate info. IMHO the auto vs. manual debate offers negligible differences, depending on car setup & driver skill, all else being equal. Sadly, I doubt any factory test numbers, or other test figures are trustworthy either, for the same reasons.

It was until your non M comment and the "lol" about closer gear ratios. I simply stated that the M's don't have it either and you spiraled out of control about how great the M cars are to which I have no argument.

Ok....so...we are now past the ///M issue. Good. Let's stay on point.

It seems to me the question at hand are:

1. which car is faster, the auto or manual ZHP, in a straight line test?

-This assumes when driving the auto...you mash it off the line (and continues through the 1/4 mile).....and the manual driver hits all shift points, at the optimal time and with max fluidity.

2. which car is faster, the auto or manual ZHP, in a track type setting?

-This assumes same expert driver, drives both cars.

No, actually I didn't at all.

If it's the same ratio on the same engine...great. But it isn't.

You fail to still realize that.

Enjoy.

IMO Manual is better at both. You chose your shift points, and it's always ideal to short shift to gain torque in any setting IMO. HP drops off alot in last RPMs

If we've got another ZHP coupe out in SoCal, I'd be all for going on a flat, straight road and run some comparison tests
Make a YouTube clip or something.

there are many of us in the Republic of SoCal, come down to autoX one month in SD and we'll get our answers

[terraphantm]

Yea, but what makes the car stay in a certain RPM range under WOT conditions is the gear ratios in the trans. The auto seems to be closer and I thought the ZHP 6 speed was supposed to be a "close ratio" gear box.

The auto has fairly closely spaced gears *until* the 3rd-4th shift. At that point there is a very large drop from what I remember. I did occasionally feel that the autos felt torquier in the lower gears... but 4th and 5th gear really destroyed it for me. Those cars were begging for another gear in between.
