A bit more than 2,000 hp in a Gallardo equals a quarter mile time of 10.293 and a mile in 23.479 at 230 mph. Pretty much unbeatable performance.
I don't know what you have to change in order to get 2005 horses out of the Gallardo's V10 apart from the two turbos, lots of boost and racing fuel. Probably everything apart from the block. But when it works out, expect to beat anybody on tarmac once you manage to find some grip.
Remember the 700 hp Nissan Juke-R that almost got a Veyron? Destroyed. 1200 hp Nissan GT-R? LOL.
