1M v GT3 testing 30-130......

[terrybGT3]

Ok, let's be straight about this, firstly neither car is standard - brief details below

The Cars

BMW 1M with DMS remap taking it to 415/475. Weight 1495kg

996 GT3 Mk1 with Manthey K400 conversion - apparently about 400/325. Weight about 1350kg

The Conditions

Not ideal - tarmac surface and a little damp in places and 11 degrees C and with a slight uphill gradient. Measurements taken with Racelogic Performance Box

The Results

GT3 = 15.4s - started run in 1st gear
1M = 16.4s - started run in 2nd gear (with wheelspin in 2nd gear - so would have been quicker in better conditions)

I did 2 runs in each car and to be honest with more practice I would think there could be better improvements made in the 1M by learning the best rpm to change up a gear, whereas in the GT3 it's pretty much a change at max revs.

All in all, the little 1M did itself proud I think. More scientific tests to come in the future, hopefully in better conditions, etc...

Cheers

Did you take a video?

Kind of surprised by this. GT3's aren't known for their straight line speed.

In dry and warm conditions a 1M with those specs should hold up against the GT3

This is not a BMW vs. Porsche, as both cars are modified.
In a straight line, it pretty much comes down to weight/HP, no?

plus gearing, aero and tires.

Unless we're talking about custom made tires, you could install them interchangeably, or on any car. It's not a characteristic of any particular car.
Gearing is a well known science. Each manufacturer specs their gearing to extract the maximum output out of their engines and onto the wheels. I would be very surprised if there were engineering mistakes made, at these levels of cars.
Aero, I agree. The Cd or each car will come into play, but we're not talking excessive speeds here... 130 km/h (I presume?) is a drop in the bucket given the HP we're dealing with.
I really don't see a point in this comparo, unless it's to emphasize one engine tune over the other.
But then, we'd need a baseline... like in OEM form 1M beats GT3, but after tune GT3 bests 1M.

Realize that we are talking about a 996 GT3 here which is a decade old car. A new 997 mk2 GT3 would post up faster numbers than that stock. There is a gigantic difference between the 996 and 997 GT3. TO say GT3's are not known for this straight line speed is laughable. Yes they are known for their spectacular handling because that is what all the magazines and people talk about. But the 997.2 GT3 does 0-100 in 8.3s stock, compared to around 11.0 for the 1M.

no, this is mph!

Yeah the 997.2 GT3 is a whole different beast but I thought a 1M would take a 996

[terrybGT3]

As I said in my original post, my GT3 is not standard. I think a standard 1M and 996 GT3 mk1 would also be very close as the performance increase with the 1M is a greater improvement over standard than the GT3 improvement.

Anyway it's a bit of fun in terms of the comparison and you could buy both cars for similar money and some people may consider moving from a GT3 to a 1M if they need extra practicality but also want a car that is lots of fun.

I assume you've had your GT3 for much longer than the 1M. The 1M is a sensitive and tricky beast to launch from stand still. As you mentioned, with more practice the wheel spin can be avoided and the sweet rpm/clutch spot will be recognized...also, a well juiced and timed shift from 1st to 2nd is crucial in the 1M to get the most out of her...this comes with practice behind the wheel

it was a rolling start and the road was damp which caused the wheelspin. In dry conditions the GT3 would be much quicker off the line due to superior traction.
