[@digitaldreamer8637]

This has got to be one of the best "On the Limit" driving videos on KZbin! That sound.. That boost. Flat six with a blow off. I'm in heaven! Great work guys! :)

[@Pandamasque]

This makes my vacuum cleaner sound like it's not really trying.

[@nickn1114]

***** it definitely sounds better than my monotonous dyson

[@dsalbatera]

ty for the pure driving upload, no bullshit music or weird camera angles

[@caseylockwood5512]

This dude's throttle control is unreal. Sick skills!

[@frogchaser]

omg that was amazing. please do more like this!

[@ErnestoJSilva]

Hermosura de video. Subir el *Pikes Peak* es el equivalente a correr en el Nurburgring por su complejidad y peligro en cada curva. #PikesPeak #PikesPeakHillClimb #Porsche911GT3Turbo 

[@rafavilla8070]

Totalmente de acuerdo, salvando las distancias claro está

[@sergiomendez3748]

Buenísimo gracias

[@mariumrajah]

That’s some of the best Music I heard .. That intake !! Turbo howl !! Blow off system…

[@ryanolson6794]

Some CRAZY shit right here. That takes balls of steel, he was consistently in the 60-100, on a road like that! No way I would ever do it!

[@eletor]

So arousing.

[@Loothansa]

Woud you like some engine with that turbocharger?

[@hillclimbracingfan5821]

Great driving by Jeff.More Pikes Peak onboard footage,please.

[@novakillerzz9490]

Solo imaginen estar en esa cabina, con toda la presion de hacer un buen tiempo, el sudor en el traje, el ruido de ese boxer y las fuerzas laterales. Que experiencia...

[@CamPayneCam]

WOW that was some amazing driving! Trying to tame that beast of a Porsche!

[@CadzZ]

very calm and very fast, amazing footage

[@c1d2e]

I can’t sleep after watching this.

[@FrankTichnor-un4td]

[@reeceengineering]

Helicopter shadow on track at 3:36 is very unprofessional of the event. It can distract drivers & slow times. Easily avoided.

[@Diax1324]

That bounciness at the top is fucking terrifying.

[@ghostassassin1107]

I think the fuel pump had failed at that point and the car was essentially cutting out on him.

[@DruNature]

oh my god this is so fucking sick!! 5:15-5:47 was intense. You gotta be a great driver to race this track and wow this man has the balls and the skills! spine tingling to say the least - wow! Side note, it's more fun to go downhill bro!

[@americangreensturf]

6:04 ish. chugga chugga chugga chugga, CHUGGA CHUGGAA

[@zanjani13]

God damn that sound!!

[@martijnvkk]

1:19 that sound are that the brakes? Nice vid btw more of this would be cool

[@MrRealjobe96]

martijnvkk if i understand what your asking the sounds is the blow off valve if im not mistaken

[@Euphorica]

Blow off valve(s)

[@martijnvkk]

thanks for the response :)

[@Aesh-om2sz]

The car has no BOV its compressor surge.

[@daphneb4151]

The BOV doesn’t make the sound, the turbo doesn’t have a BOV that’s why

[@KriegBoy]

There's a Chihuahua stuck in the front bumper.

[@bobbyquinn4952]

KriegBoy ahahah I can hear it

[@leivabernie]

😂😂😂😂😂😂

[@theswimmingcarrot8496]

please explain to me why he doesn't have to use the clutch when upshifting but he does while downshifting

[@tommy4862]

The Swimming Carrot Because it's sequential gearbox you don't have to use clutch it's automatic. But when he downshifts he uses manual clutch so he can rev match with throttle which makes the downshift smoother. I guess those cars don't have automatic rev match and if he wouldn't use clutch the revs would climb up so fast it wouldn't be good for gearbox. I am not 100% sure if that is the reason but it makes sense to me.

[@Bullitt1768]

tommy4862 correct, and not rev matching can throw the vehicles weight forward and cause a loss of control.

[@theswimmingcarrot8496]

Thanks

[@AndiSabin]

The Swimming Carrot In a sequential it's up to the driver if he uses the clutch or not. You can use it all the time, or not at all. Some pilots brake with left foot and blip the throttle when downshifting (it dosen't work if you don't blip). Others simply heel&toe with no clutch, and the third kind, like this guy, use it like in a H-manual. By the way, you can also no-clutch-blip-throttle-downshift in a H-manual aswell. It's all about prefference.

[@mcwriter007]

AndiSabin Nothing personal ... "this guy" happens to be one of the greatest Porsche racers of all time - both factory and privateer - and is also a preeminent photographer, cinematographer, filmmaker, and racing consultant. AND - because I worked wlth her for a few years way back when - he had one of the coolest Moms of all time, Viva Margie!

[@FrankTichnor-un4td]

Durable 6;

[@Frankprane-lo3yf]

Snow high mountain drop off pikes peak a+

[@Gohot229]

Sounds like the turbo's don't like altitude.... I could be mistaken.

[@Turboy65]

What's happening when the car makes that coughing sound so often?

[@RacersUnited]

It's the turbocharger's blow off valve.

[@Goodstegosaurus]

+johnsoncm65 Near the top, he was also experiencing some fuel pump issues, so the car was cutting out

[@Aesh-om2sz]

No the car has no BOV, its the compressor surge

[@daphneb4151]

Compressor surge no BOV

[@joaoa13portugal]

Why does the BOV hiccup that often? I get that sometimes it happens when he's not fully on the throttle, but other times i could swear he's smashing his foot down and the BOV still hiccups. Anyone care to explain?

[@robertvanderbush737]

Compressor surge because there is no BOV, it's setup that way so when you let off and get right back on throttle you don't lose boost

[@DailyDrives]

Damn it is bumpy as hell up top.

[@izzu2din979]

i luv the turbos XD

[@brandoncruz517]

Those blow offs are crazy! Great vid

[@Aesh-om2sz]

The car has no BOV

[@daphneb4151]

Compressor surge

[@djbrissette]

Since when are GT3 turbocharged?

[@BrianKrahmer]

dB it's apparently not a spec version. the turbo is custom

[@mikeincognito]

dB The car, as the turbocharger is pretty custom as well..this is not a standard GT3 but a GT3 Cup.

[@ghostassassin1107]

Near the top, it looks like the fuel pump was mucking up like in the 2014 run.

[@hakonhyvik6257]

Ghost Assassin yeah, something is fucking up. Maybe too small fuel cell so when running too low and with high G force, he vant Get fuel? Proper fuel cells have foam inside to prevent that. But he is hitting high G force. Or he need a "catchtank" for the fuel so he always have fuel to the pump.

[@Cubitalipino]

What is that squeaking noise? Not the turbo spool. Is it maybe the BOV?

[@falkmk2]

there is no bov, so you here the compressor surge when he goes of the throttle

[@daphneb4151]

Not a BOV, a lot of people mistake it for the BOV making the sound but it’s really the compressor surge

[@FrankTichnor-un4td]

Turbo clutch

[@FELiPES101]

This is the kind of car we should be seeing at 24 hours of Le Mans from Porsche, not some silly super regulated nanny race with everyone driving the same thing.

[@blurreaper1238]

Tututututu sttttt ststststtsstts. Fuck that's incredible

[@6ixss]

6:03

[@pricklypear300]

GrandOldPuba no time to dwell on the past when the present is going through hundred miles per hour. he might have probably just thought "shit, there goes another half a second", forgot about it, and carried on :)

[@DooDicky]

what kind off shifter is this ?

[@blurreaper1238]

Sequential

[@daphneb4151]

Sequential which means you don’t need a clutch just like paddle shifters

[@robertvanderbush737]

Sequential, like motorcycle, push forward for downshift, pull back for upshift. makes for faster shifts

[@jlschmugge]

what is the skweaky noise?

[@stonedmole2351]

jlschmugge compressor surge

[@daphneb4151]

Yeah no BOV

[@Pandamasque]

Also, he needs a way faster rack.

[@carloemiliozuniga]

thumbs up if you saw this on carthrottle

[@matheusgsi]

that compressor surge hurts my ears :/

[@robb2505]

9:37 = pucker

[@sarjentskwirrel]

that compressor surge sounds like and angry chihuahua

[@FrankTichnor-un4td]

Bernard

[@Ten1987]

Pure Ear Pornography :D

[@GritForceEnduro]

looks like it (the video) is being sped up. Takes away from it imo

[@DarylHiers]

Look at the time on the video, take off the first few seconds for the intro and you have a 9:46 run.

[@Frankprane-lo3yf]

Loose the steering; we good 9mm service bernard

[@harpella]

Why would they allow an angry Chiwawa in the car during a race!?!? I am appalled and everyone involved should be arrested!!! Animal control should be contacted to make sure that poor animal is all right. You can hear it barking in despair the whole race! Shame on you!
