My Elise 111R RM out runs my Gallardo, LMF and CTR.
I'm not bragging, because honestly, it annoys me that my Porsche & Lambo can't outrun a 310hp car... My ZR1 RM beats it though.
The above is based on Deep Forest Raceway.
If the track doesn't require a top speed of more than 150, the Elise is suckin fexy...
Hell, it keeps up with a stock Veyron at the High Speed Ring. That should give you an idea. 1-2 seconds slower per lap, but it's amazing it's that close.
