@@hpa101 Speaking of burble, please could you guys do a video (or a Short) on precisely how ignition and fuel are cut/retarded for soft rpm limiters, popcorn maps, and what I call "DSG farts"? 😅 Regarding soft rpm limiters, I've never been able to find deeper explanation beyond a very vague "the ECU cuts selected ignition events." And on popcorn maps: as much as I hate them, I'd still be very interested to know exactly how ign/fuel are cut to get those popcorn sounds, and also those fart noises VAG cars make between semi-auto gear changes!

A clean, smooth calibration is a thing of beauty in and of itself. Watch ANY well-setup racecar's onboards. The biggest thing you'll notice is just how SMOOTH the shifts are - especially on part-throttle upshifts and off-throttle downshifts.

I always knew pops-n-bangs were bad, but i never thought about the fact that it literally forces percussion into the valve - and so into the camshaft. Great explanation.

Pops and Bangs, modern day ricer mod. I remember seeing at a car meet, there was an exhaust competition, this R34 gtr had massive pops and bangs, then he had a knocking sound coming from the valve train. He managed to some how slowly "massage" the knock away with gentle revs. Also had my mate piss out coolant in his evo, just created excessive cylinder pressure and pressurised the crankcase. Needless to say, not great for any engine.. Just stick with burbles and turbo noises.

@diogovieira5442 ай бұрын
It is not to my knowledge that this car has torque sensors in any shaft, that would be relevant piece of information for Quaife. In this case, a car with above average performance, does anyone know what the instantaneous torque is after an instantaneous reintroduction of power? In my opinion they are rebuilding the gearbox because this is one of the best known cars on the internet to use a gearbox from them it was widely reported that it had problems during the race and they have a reputation to uphold. Making mistakes is part of Human nature, and only those who do nothing don't make mistakes, admitting mistakes demonstrates humility, this is how we evolve.

@hpa101 These videos are interesting, exciting and packed with a lot of useful information. My only criticism is that in every video the interviewer clearly understands the topic very well and spends most of the interview guiding the interviewee to say the right thing in the right way. Could HPA instead do any needed research upfront and then distill the information into a concise informational video without the need to show an interview? That way, information would be presented accurately and succinctly, much like in the many great HPA courses.
