That is true but it was a bit more than just that.
I wasn't wheelspinning so I don't think it was down to traction, more likely the extra torque, in theory a peak of 268ft/lb vs 224ft/lb, really was there in the mid range and made the difference.
Even slow corners on circuit rarely mean you have less than 3-4K revs dialled up when you get on the gas, so it's clean mid range pick up you need and the F355 seemed to have a bit more of this than my car.
For comparative purposes, at the same event I could not keep up with a couple of M3 CSL's running sticky Michelin Pilot Sport Cup tyres.
