Last week we introduced you to this very cool Lamborghini Jalpa that was able to pull 10-second quarter mile runs thanks to the supercharged GM-sourced LS1 engine that got crammed under its rear hood.
Motivated by the 500+ horses pushed out by the 346 cubic inch engine its Magnuson compressor, the Italo-American hybrid needed only 10.6 seconds to complete the 1320 and crossed the line with its speedometer at 130.8 miles per hour (210.5 km/h).
Well, if you thought that was impressive, we’re happy to report that the Jalpa managed to improve its quarter mile time by more than half a second, climbing into 9-second territory. Specifically, the second run in the video you’re about to see below froze the stopwatch at exactly 9.99 seconds. The quarter mile speed was also improved by about 8 miles per hour up to 138.48 mph (222.86 km/h).
While many of you might find it awkward for an owner to drop a GM V8 engine into a Lamborghini, the Italian company was no stranger to eight cylinder mills back in the 1980s, when the Jalpa was built. The entry-level sportscar was powered by the same 3.5-liter V8 that founds its way into the Silhouette. The engine delivered 255 hp, about half the amount the 5.7-liter LS1 fitted in the vehicle below.
