Not being sarcastic. I once owned a highly tuned Eagle Talon which had massive lag. It was a thrill every time the boost (eventually) kicked in. It’s probably one of the reasons that makes the F40 exciting to drive. One of my race cars is a Praga R1T which uses a turbocharged 2.0 Formula Renault engine making 380hp. The lag is about 1 second which, needless to say, requires an adjusted driving style. I’ve never driven a street car that doesn’t have lag - Pista, 720 and GT2 RS included. While they respond immediately to throttle input, there is a delay before peak boost is reached and acceleration is at its full potential for a given throttle position and RPM. Driving an 812 or Speciale after getting out of those cars makes it especially obvious.
