3.0i manual performance data

[Mr Whippy]

Here is a 0-60mph run without DSC/DTC, my first and only attempt.


And here is an averaged power/torque plot for a power run using my G-tech Pro RR, and an associated Excel calculation sheet (not sure what is going on with the losses, they were set to 22.5% though, for 2nd gear runs)


Nice to see the car perform very close to expected parameters, with 0-60/0-62mph being almost perfect (0.1s out, I'm a noob ), and the torque peak/plateau being about right, and the mix of power/torque being about right too!


Will post more data as I get it. Next job is to try a performance panel air filter or three out, and see what differences arise.

Cheers

Dave

Very nice post. Will be waiting for more data for the performace parts

Good stuff!

Still reckon mine would have it though!

 

[Mr Whippy]

Just to put it into perspective, that wasn't exactly like t20lau's launch... think more like in this video @ 50s

Is yours an auto Dannyboy?
Cant tell from your sig what difference yours is for you to reckon on beating him!

Certainly is! A 3.0 auto on heat that goes round slapping 3.0si manuals in the face upto 70mph!

 

[Breaker]

It's OK he did a standing start test against a 3.0si manual with a half asleep driver** and now he thinks his is faster!




** :wink:

 

[thestig]

Sorry mate, but there is no way you'd beat a manual.
Your 0.3 seconds slower to sixty just over the equivalant 3.0i manual and 0.5! seconds slower over an si driver.

If you did it properly with the same driver over 3 or 5 runs and averaged it out Im afraid its no way jose!

 

[DannyBoy]

All I can say is the car is "special"....

 

[thestig]

ok, Ill give you that one!
:wink:

Oh I dont know stiggy, you dont have to give me anything. What happened, happened.

The auto is quicker off the line and through the early gears like it or not. If its quicker through the early gears than a 3.0si, can you imagine what the car would do to an early 3.0i manual stiggy.

 

[Nerra]

We'll be doing the same tests in my SMG so it will be interesting to see what happens.

 

[Mr Whippy]

I had to feather my throttle (I'll post up the full plot of rpm's, g's, speed, etc etc tonight to go with this run) a bit in 1st gear, I think flooring it in SMG and letting it do it's thing would still need some feathering, warmer tarmac/tyres might help though, for both our cars.

Either way, I think the times are pretty much spot on to book and test data.

I honestly do think the issue is that t20lau can't launch his car well, I will try again with tcs/dsc and see what difference it makes. I noticed a huge difference in having it off lets put it that way. It really kills that 1st gear surge and that is enough when up against an automatic that makes a fast start easy!

Was Jose Mourinho the previous owner?

 

[thestig]

Your deluded.
Many many magazines and independent testers have done the numbers on these cars and proved the manual to be quicker to 60.
you lose out on both the extra weight of the box and the torque converter slushing the gear changes (sport mode or not).

Just one at random (Parkers), I can find plenty more!

3.0i Petrol 0-60 Top Speed

3.0i SE 2d 5.7 s 155 mph
3.0i SE 2d SMG 5.7 s 155 mph
3.0i SE 2d Auto 6.0 s 151 mph

3.0 SI Petrol 0-60 Top Speed

3.0si SE 2d 5.5 s 155 mph
3.0si SE 2d Auto 5.8 s 155 mph

The facts are unrefutable.
What happened happened because your manual driver was James May!
Sounds to me like someone has a chip on their shoulder about compromising and buying an auto in the first place!
:wink:

 

[Dreamer]

Interesting Dave! Looks like its on the money, and peace of mind the cars performing as it should.

Not sure if a filter will make much odds but worth trying for the fun of it. I have the Helene filter and didn't notice a scrap of difference, but then i wasn't timing anything.

Sounds like your having fun messin around anyways which is what its all about

 

[EdButler]

Lol at this thread! I do agree with everyone else that the Auto will be plenty slower if the Manual driver actually knew what they were doing. I think you caught him alseep mate and even so, bragging about it in your Sig isn't that smart. I expect to see 'race' threads on a Corsa forum, not here.

Auto's really cannot launch as well because with a Manual; you can micro manage much better with both pedals matching maximum torque without wheel slip. Autos tend to bog down and lag at the start as you have no control over the launch RPM. The Z4 Manual however is a tricky customer to launch anyway due to its Clutch Delay Valve. What you do with the clutch pedal is heavily dampened. If you get rid of that, the manual should be better still.

RWYB day at Santa Pod anyone?? Id love to try for a 14.0

I'm still trying to figure out how Motor Trend got the 2007 3.0si roadster 0-60 in 5.1 sec. Maybe it was a downhill track.

[Mr Whippy]

You have to watch out on these timings, because they can often include rollout from the drag strip on their tools, so the time to cover the first 12" is ignored in the time... that can be 0.3s worth.

As you can see my plot starts at 0 and speed 0

There is no doubt that a manual is quicker on paper but in real world terms with average drivers, the auto would probably win most of the time.

The thing is, an average driver would easily be able to consistently get the quoted 6 second time to 60 where as someone in a manual would only get there in .3 seconds quicker if they did a perfect launch and gear change. This, contrary to most people's belief is pretty damn hard for average joe.
