V12 Race Car Engine Roars Back to Life!

[@ldtenenoff]

I could watch these 2 gents all day truly real live Legends

[@michellee8369]

And it still boggles me why this channel doesn’t have hundreds of thousands if not millions subscribers. The oldest most confident full of knowledge legends right here making it happen and thank greatness GQ is recording it for us thank you 🇦🇺

[@CanIbeFrank]

I agree 100%

[@GregQuirin]

@CanIbeFrank! I watch your channel all the time - Hope to have the number of subscribers you do some someday. Thanks for watching the channel. Always open to suggestions has to how the grow the channel. Thank you Greg Quirin

[@GregQuirin]

Wow, thank you! Hopeful to grow the channel some more in the near future! Thank you Greg Q

[@twatdidusay304]

I agree 💯, and I say the same thing about David Vizard's channel as well. He's another legend 👍💯.

[@krusher74]

becuase your average "car guy" doesn't know shit about engines. The Nornmies just want some exhaust backfiring and some sensational bullshit. 80;000 people go to a nascar race how many got to watch salt-flats record racing?

[@stevewelborn8744]

The engine sounds amazing. Very responsive

[@GregQuirin]

Thank you Steve!

[@johnd5805]

Love the jack stands.

[@lutach]

Aside from all the great comments, I'll add a new one........we need longer videos. You all are legends and thank you for sharing this amazing experience.

[@karlalton3170]

Watching from Thailand 🇹🇭🇹🇭 Awesome channel just what a retired engineer like me likes 😁😁🤘🤘🤘

[@GregQuirin]

Awesome thanks for subscribing from Thailand

[@chrishenniker5944]

Show this to your local Deak Wen, they will love it.

[@Motor-City-Mike]

This isn't mindless rhetoric like so many other channels, this is for hardcore, eat, sleep, dream, maximum built-not- bought, diehard engine/race car junkies. Designing and creating complete race engines of various configurations isn't for just anyone

[@GregQuirin]

You are 100% right - Even I'm starting to have dreams at night about this stuff.

[@patawic]

If the laptops charger is plugged in (and even sometimes without) you can get EMI through the usb plug which can screw up sensor readings etc. Try unplugging the charger, you could also try grounding the laptop to the car chassis. I'd also try running the engine with the alternator disconnected to rule out if the alternator is spitting out dirty power. You likely have the screens RPM signal being linked to the wrong value.

[@GregQuirin]

Lots of good info here, Thank you for the suggestions. Greg Q

[@rickbegeman4371]

I've had problems with USB in some installations, I switch to RS232 when I can to avoid problems. I bought a notebook that has a native RS232 port to facilitate that.

[@lasskinn474]

what is paramount with usb is good quality cables with choke magnet filters if you try to keep the usb over serial going without a hitch over a longer cable. do not use cable extensions. usb over serial is a very fickle mistress. you can buy an usb isolator too, can help a bit. or cut the 5 volt line and insert another stable 5v if the device being talked to requires it, if the problems are from that. if the device takes power from the usb and it's a long cable this can help a lot. computers often output just nominal 5.00 and it'll drop easily over a longer cable. phone chargers output 5.1-5.4 and that's fine for any device, but the point is the voltage at the end of the cable stays above 4.95 with higher loads. you can also buy a rs232 to bluetooth serial dongle if the device has serial. this is a very handy method to make older devices wireless.

[@mailbalazstomori]

@@GregQuirinFor a first check its a good start to measure voltage between the usb cable and the port on the computer with a multimeter. If there is voltage its some grounding problem, for the nasty emi and alternator related stuff a good scope is needed but genereal good grounding for sensors (star system one connection point to the ecu sensor ground pin and separation from the chassis ground, so on. You guys rules! Nice to heat it running.

[@stevenlane9272]

Love watching these videos. Hello from England.

[@GregQuirin]

Thanks for watching from faraway!

[@InexorableOne]

This is what men used to be capable of. The Ford family was just one of many. This is a great show of what we all could do if we put our full minds to whatever we wanted

[@andrewmontgomery1763]

Uh there’s plenty of people nowadays doing incredible things… like the duo making a Ford DOHC 6.8 liter v10 for instance

[@yobringitondown5565]

Love watching these guys. True champions in racing and in life. Thanks for making these videos! 👍🏼

[@LimestoneCoastCustoms]

Honestly, this is the side of LSR I truly miss ! When our streamliner team disbanded, though I went onto helping the club run the event including scrutineering, this is the next closet thing to actually running on the lake!! Once the building is done, it's the sorting of the many issues that always raise their head. Thanks once again for sharing Greg!

[@bobo1959er]

with the plenum blocked off how is it getting air?

[@scottsosss]

I didn’t know VP makes jack stands 😂

[@GregQuirin]

They serve for many purposes around the shop

[@leehrh263]

We'll see you guys at El Mirage in a few weeks. Good luck!

[@GregQuirin]

Can't wait!

[@davidtappe5337]

Amazing sound.

[@markbowden7238]

I watch 2 channels that intend to show us - speed records being broken on salt either hopefully, possibly, maybe or actually. I'm looking forward to seeing it happen, here, despite not being an engineer I can appreciate that V12 is an incredible achievement. The other channel I watch is 2strokestuffing about one man in Europe who intends to set a new land speed record for 50cc motorcycles. Seriously he could do with a bit of help because imo he could have overlooked an important fundamental, or he could be about to make progress.

[@GregQuirin]

Thanks for the info I will check the other channel. Greg Q

[@markbowden7238]

@@GregQuirin 👍🙂

[@chestrockwell8328]

Surprised the engine ran at all with the piece of plexi glass basically sealing off the air intake. Gonna be wicked when all the tuning is sorted.

[@Richard-n2w1g]

It looked to me like there were a bunch of tiny holes drilled in the top. Basically just a big plexiglass air strainer. The holes were just big enough for air to flow, but not so big that large pieces could be drawn in

[@Richard-n2w1g]

If you pause it at 3:32 you can see them pretty clearly unless you have a not good Internet connection 😅

[@chestrockwell8328]

@@Richard-n2w1g Thanks, it was late last night when I watched and my tired eyes didn't catch the little holes. Right now I've paused at 1:12 mark and there appear to be about 1/8" holes drilled around the perimeter of the plexi at the edge of the air box.

[@Metalcrafter]

Thank you, Greg. Can you please do a couple of minutes on the intake design?

[@GregQuirin]

Kevin is making an intake for the new 5L v12. I will see if I can get him the explain how is building it.

[@davidaarons2488]

Always those little bugs after engine install. Thanks

[@pauldemeester9298]

Can you put up Cape cranking out the videos? We wanna know what Pete’s doing every minute you guys are making great content.

[@johnmcdowell6795]

I wish you would of called me to come over and see this

[@GregQuirin]

Are you in the San Diego area?

[@dano4572]

BEAUTIFUL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! AND YOU ARE A GREAT HELP WITH THEM!! WE ALL NEED A LITTLE HELP,,,,, YOU ARE THERE HELPING. THANK YOU.

[@clintonsmith9931]

My brother use to use a piece of blue chalk to mark on each exhaust header on airplanes to see if they were running. The chalk will turn brown on hot cyl. Just thinking.

[@GregQuirin]

That's good info

[@__Michal]

your scan port pinned wrong?

[@GregQuirin]

The pins are integrated into the mother board of the ECU - Probably noise on the USB cord

[@michellee8369]

These guys know. Love this channel thank y’all

[@vlachyna]

BIG toys for BIG boys….🎉

[@toddclark332]

Can't wait for your run guys ❤👍😁💙

[@daos3300]

signal noise would be my guess based on knowing nothing about any of what has been done or how.

[@GregQuirin]

I think you right about that!

[@keithtobin5369]

Awesome keep up the great work. Thank you for the coverage

[@pat8988]

I imagine that the car computer would be happier being installed on the cool side of the firewall…

[@popeye089]

Great video as always. Thanks guys

[@frankpatterson5843]

Air intake flow path?

[@GregQuirin]

Enough air to start up and idle. Cover removed when in competition mode

[@mutantryeff]

Keep us up to date on computer issue(s)

[@tiitsaul9036]

Was the laptop charger plugged in. I've had some trouble with electrical interference when laptop is plugged in mains power.

[@GregQuirin]

Go to know we will for sure try it unplugged from the wall

[@PiDsPagePrototypes]

While respecting what has been achieved here, I can't help but wonder if more could have been achieved by applying the skills and machining shown here, to custom heads and cams built on the LS V12 block and crank?

[@dennisford2000]

Look at the boards with a loupe . They can crack especially at solder joints. Use heat and cold.

[@pamdunn8454]

as a bench racing observation , maybe the throttle positioning sensor is not grounded or the engine block needs an additional ground , and the system is looping through the PC ?

[@FlightEngineering1]

I had the same issue with my Fuel Tech FT600 disconnecting / connecting from the PC randomly when my engine was on the dyno. I never found the issue, but could have been ignition interference maybe?

[@GregQuirin]

Thanks for the info!

[@enesfazlic6017]

There is something flapping around behind the LH Exhaust cam sprocket in the video.

[@GregQuirin]

Good eye - that is the homemade camshaft position sensor trigger tab passing in front of the sensor

[@RestorationWatch]

You need the laptop plugged into its own power supply so it doesn't drain power from the engine management computer through the USB port with the engine management being incapable of dealing with the drain placed upon it and the power 'sags' would be my guess.

[@lambda7652]

This is some sort of EMV problem. You can try the following things. 1. Unplug the Laptop from Power and Get a USB Isolator! the slow ones (ADUM3160) are cheap. the full speed usb 2 from topping cost ~100$ 2. Is everything concreted to chassis ground and chassis ground to earth ground 3. Add (lots of) clamp on ferrite to signal wires

[@gpxracing6592]

Is the USB cable shielded?

[@johngato737]

Is it too many terminating resistors when the computer is hooked up?

[@GregQuirin]

I wouldn’t know?

[@philmariop]

Time to RTFM. Suspect electrical noise, grounding are problems, as others commented.

[@GreasyFingerboys]

I have had issues with precision temperature recorders picking up noise or strange behavior when plugged into a laptop. Found that plugging into a desktop computer fixes the issue.

[@GregQuirin]

Thanks for the info!

[@jamestemple5696]

Computer will cause a Grounding issue…?

[@dennisford2000]

Wow

[@richardmorton1310]

Just a tad bit of oil pressure.... pinned at 100 psi at idle.

[@didiz01]

Pete and Kevin should get a movie made about them, these guys have made such a history and still continues to do so. its like the worlds fastest indian but 100x better

[@GregQuirin]

This is the true story of the fastest Indian- lots of innovation within the landspeed racing community.

[@woodyworker7287]

how is it getting air? Look like plexiglass cover stops all air flow

[@MidwestMikesCarsAndCooking]

I am wondering the same thing!

[@pauldemeester9298]

It’s running in limp mode when it’s plugged into the computer it’s got a poor connection somewhere

[@GregQuirin]

I think it is a poor connection or issue with the USB cable

[@bricewiese5082]

Unplug the display with cpu hooked up and try it

[@elizabethcherry920]

I have never seen a V12 engine in a top fuel drag car, who's the manufacturer

[@joshjones3408]

Maybe when it's plugged in it's power interrupts .. between computer an the brain in the car ....

[@fourfortyroadrunner6701]

Greg, not your best video. Slow down on the panning, please. I REALLY enjoy these videos. I'm 75, old guy from N end of Idaho

[@GregQuirin]

I will try however, usually I am holding the camera in one hand and trying to help the crew. (Multitasking) This is more of, on-the-fly at any moment unrehearsed video documentation. Prefer to keep it organic and not a production video. Thank you for the tip!

[@oldschoolmotorsickle]

Electronic glitches like this will try a soul’s patience! The bug could be anywhere, and anything. Throw in a computer or two, and the potential failure points probably number in the millions. My sympathies for the people trying to sort this one out!

[@GregQuirin]

Always fun!

[@77Sunsetstrip]

Call Shane T at Motec

[@rjung_ch]

Wow, that sound in idle, loud and furious. Wonder why not all of you wear the ear protection... so loud! No idea why the computer is messing it up. Hope the guys find out why. Cheers 👍💪✌

[@evansisco]

I would think it’s the tuning firmware on the laptop needs to be reloaded or re-downloaded. Tuning software malfunction.

[@evansisco]

I would definitely retry downloading the firmware for example (version 1.2.1) try reloading the firmware for whatever version your tuning software is using
