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. I wonder what kind of difference it makes depending on if its a pushrod/rocker arm, roller cam hydraulic lifter, or solid lifter setup?
So glad my tuner is heavily involved in motorsport and hates pops and bangs as much as i do! Scotty is a walking encyclopedia when it comes to tuning!!
Curious if different weather climates will affect the flat foot shifting , introduction of snow, or rain conditions? Enjoyed this episode of HP Academy. Thank you, Boss Simon
Is there any advantage to cutting fuel AND spark vs just cutting fuel? Doesn't seem to me like it would make a difference either way but just curious if I'm overlooking something.
Hailtek did all they could with old technology, but they can do better by designing a transmission w/o lifting your foot by adding parallel gears. Running 2 gears at the same time you can transition w/o letting go of torque to shift.
I never thought of what pops and bangs are doing to the valve train😮 but it can't be good for your catalytic converter, turbo, and exhaust system either
As far as rev matching on the upshift goes - is that just a matter of sacrificing mechanical sympathy or does the fuel/spark cut drop the RPM enough to match the new ratio?
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.
Why so sloppy? You know the speed of the car and the next gear. Almost all cars have an electronic throttle and the ECU completely controls the engine. You can set the engine RPM exactly for the next gear.
If only we were that organised to actually have a plan on what we film and when we release it 😂 I had completely forgotten about any issues they had. Reply with more detail on what happened beyond the video linked below (if you know anything that is!) noting Quaife also came to the party to rebuild the box. That fact and also how you can see it popped out before a shift means Scotty here is safe I reckon 😂 Ultimately this is a race car doing race car things and sometimes things break 🤘 - Taz. ruclips.net/video/O6LFw0K1D24/видео.htmlsi=Qid9RERcYweRMadf www.ferrarichat.com/forum/threads/nice-ride-so-this-may-cause-considerable-offence-stanceworks-308-gtbi-honda-k24-swap.634552/page-25
That Quaife is rebuilding. Wonder why they would do that if it was a simple tuning issue which there is plenty of data from the car to identify if that was the case 😎 It is a race car doing race car things, and no one is infallible, but be careful with the finger-pointing like this even if it's in jest 🤘 - Taz.
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.
We all have opinions, but laying blame based off nothing but opinion from a few videos on the internet is not always an opinion worth sharing is the point I was trying to make there 🤘 As mentioned, no one is infallible which extends beyond those working on the car 🤘 - Taz.

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.

That way, information would be presented accurately and succinctly, much like in the many great HPA courses.

Curious if different weather climates will affect the flat foot shifting , introduction of snow, or rain conditions?
Enjoyed this episode of HP Academy. Thank you, Boss Simon
I had never considered the valvetrain being harmed due to a poor quality "crackle" tune! Thank you for always sharing valuable information with us.
Love seeing 2 smart guys like Scottie & Andre talk tech 👌
Necks were hurt during this interview
This is why I love TA2 class
awesome interview and questions
Is there any advantage to cutting fuel AND spark vs just cutting fuel? Doesn't seem to me like it would make a difference either way but just curious if I'm overlooking something.
Pre Detonation
Just fuel can cause a lean condition
Hailtek did all they could with old technology, but they can do better by designing a transmission w/o lifting your foot by adding parallel gears. Running 2 gears at the same time you can transition w/o letting go of torque to shift.
I have had so many questions about this and you just answered them all. Thanks!
god i love when these two talk on camera
So do the same issues with the exhaust valve apply to 2-step on a drag car (or my road car with launch control)?
Yes,even worst, i have broke rockers arms and bent valves
I never thought of what pops and bangs are doing to the valve train😮 but it can't be good for your catalytic converter, turbo, and exhaust system either
Man, we sound similar, Aussies and Kiwis. I suppose we are the same people with the same ancestors from the same places.
Accents and how they form is pretty fascinating eh! - Taz.
i had pops and bangs tune, ignition cut flat shift is the exception
Interesting video! Thanks for the info and explanation!
I gotta find that video that describes the issue with up shifting where the sr20 valves end up in trouble. Is this an interference issue?
No, the shims will fall out. The way to fix it so that won't happen is to dump the shims and Tip the valves which means custom valves.
@@spooler7828I thought the non VE heads also broke rockers
I've delt with the Sr lash pad issue for years. Hks or gk tek rocker stopers. Limit rpm delta to only 400 rpm.
Awesome video as always
Cool, but not what I expected from the title. Better one would be "Dogbox Controller Magic"
Legend has it that Scotty is only 1.65m tall
He sure is! But only while sitting 😂 - Taz.
www.hpacademy.com/assets/Taz-Articles-and-Blogs/9276ec2192/short-andre-tall-scott-hilzinger.jpg
As far as rev matching on the upshift goes - is that just a matter of sacrificing mechanical sympathy or does the fuel/spark cut drop the RPM enough to match the new ratio?
Person of height
My Corolla hatchback exhaust does a pop it naturally once a while, is that okay?
Great video good info
I have to mention damn Scott's tall
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.

3:09 is that a i4 or a rotary start up?
Tuning Fork and Tuning Desert Fork
this is essentially the same as a motorcycle quickshifter/autoblipper
Awsome video
In those days there were giants in the earth...
Cant you use the throttle, a DBW throttle to do the same thing?
Will bring boost down on a turbo car.
@@mandytuning So if its a NA car, its no problem then?
yeah Scotty!!!
Why so sloppy?
You know the speed of the car and the next gear. Almost all cars have an electronic throttle and the ECU completely controls the engine. You can set the engine RPM exactly for the next gear.
Andre interviewing Andre the Giant! 😂
How’s the neck after that interview?
Is Scott tall, or or is Andre short? Holy smokes.
Scott is BIG.
I have a carbureted one, sometimes I turned it off on load, it pops heavily, it's that bad?
its not good, but you cant cut carb fuel feed.
Unless your carb has an air cutoff valve it will pop on decel. No jets or needles will fix it.
hmmm 10ms, if you cut that in half, and assume 30 shifts per lap, thats 0.15 sec!
Scott is bigger in real life.
But I love the pops and bangs
They can just come with a risk in the situations discussed - Taz.
@@hpa101does a turbo hurt or help with pops and bangs?
Jeezuz that dude is like 8ft tall
i always hated this tune and the fact that people think they are cool with this doggshitt tune. an ignition cut bang on shift is much cooler
You should stand up when interviewing people.
That feeling when you don't have valves 💪
Some one stole all the food as a kid. Sheeeeeweeeee.
My turbo gives a loud bang after shift witch i love, these guys with their golf gti's pop and bang after acceleration ba bab ba ba ba ba is stupid
So its basically just a bidirectional quickshifter on a sportbike.
Got to admit....kinda tickled yer embracing the rising sun pony....neat hybrid making better it seems...
Oh gosh its not ear it is air mister😂😂😂
