I'm loving the unbridled half-assery of this project, Paul. You and Charles are the Clooney and Pitt of the VAG world. More power to you both...literally. :-)
Knock back the timing 3 degrees. Don't take the fuel from the rail, likely causes a pressure drop and lean condition. Don't use nitrous on a RR. Tyres can't break loose so puts extra stress on everything. Awesome video! New engine time!
The guy on the phone has the right answer. The extra heat expands the rings, shortening the gap. If the gap closes and still more heat is added, the expansion has to go somewhere and will flake off the piston edge upwards. BOOM. Also using a progressive controller so you're only doing max flow at your peak power RPM is beneficial. That 100 shot at 5000 RPM is 40% more stress, but down at 32000 RPM it was 100% more stress.
AWESOME! You guys didn't check what the ACTUAL fuel pressure was with a reliable fuel pressure gauge, did you. I have about 40 years of experience with nitrous and can't emphasize enough that you have to be accurate with what the fuel pressure gauge says to correctly know how big a nitrous jet to use. Also, you weren't usuing a nitrous tune which is boost referenced.... You were supposed to pull out a lot of timing under boost! Andrade was spot on about cylinder pressures too with a turbo on nitrous! The cylinder heat was so much that it closed the ring gap and destroyed the ring lands and in turn, the piston, then the rod. I know this is 2 years old, but GREAT VIDEO!
I was running nitrous and turbo back in the 90s when people said it wasn't possible to do. Everyone said I was crazy, now look most everybody puts nitrous on forced induction. Most vehicles can't handle both in stock form. I was running on a second gen eclipse 4g63 head studs and stage 2 cams. Tuning was done by me cuz nobody wanted to touch a turbo and nitrous car at that time. I put 200k on that car racing it and sold it with the og motor still running like a champ. Now days cars are made of cheap metals and plastic engine parts
There was a really nasty MK2 GTI that ran a 12V VR6 with nitrous and I'm pretty sure it was running 11s, but that was a long, long time ago and my memory is a bit fuzzy. It was a mint-green colored GTI. I want to say that it was spraying a 150 wet shot?
Great video! I have a few theories on why it blew up. I was trying to tell you by yelling at the screen, but you didn’t hear me. The number 1 issue with your wet nitrous setup is that intake manifold is designed to flow dry air. The back 2 pistons was getting all the fuel, while the rest of the intake track was dry these you had an extremely lean situation in the front pistons. If you ran on O2 sensor in each header tube, you would see it immediately.
Nice work boys . Very informative, the compounding effects NO2 along side forced induction .The multiplier effect . As they say less is more. Great R and D and cheap lessons for the viewer. Keep up the good work.
Today I wached your video and was laughing more than I should, I mean, I,m sorry that you blow you engine but the way you two handled it and your honest suprise when engine parts went "external" is great.. Last couple weeks I'm working really hard to finish up my buissnes in garage so I can go on vacation and I'm tired and depressed, but not today, you made my day thank you for that!!
Nitrous can be a very safe power adder. It’s when you get inexperienced folks who have never actually tuned ignition and fueling maps with knock sensor and wideband O2 sensors who give it a bad wrap. I ran a very progressive 100 shot on an AEM infinity stand-alone ECU with knock sensors and wideband O2 on a VQ35 for two years before I sold the car with no issues. Granted I developed the nitrous map to ramp up solenoid PWM with increasing rpm and MAP, with active ignition retard for knock, using larger injectors and dry injection.
Unfortunately we have a strict budget for this drag build otherwise we would have taken better precautions. This bottom end really should have gotten Rods to run nos
This was awesome! Y’all’s faces when the engine let go…priceless! Loved it when Paul says “probably should have called the expert first, but as formerly mentioned, I make horrible life choices.” Lol.
I have a 12” vw passat 2.5 With 50 shoot wet , works great.. all internals stock 90k miles originals( no tune ) We decided to do it just out of fun and it works very well .. of course we need to tune it, and if in the future I want to put more nitro to prepare the engine internally
Aww, poor TFSI engine. Having owned 1 and worked on 2 of them, I know they were great (despite their flaws), but they haven't aged well. I would have been reluctant to try to go too much past 300 whp on a TFSI with that many miles on it. ..."should have talked to the expert first"... Measure once, cut twice? 🙃 It's always a good time seeing you and Charles work together on a project.
I actually put a ZeX kit in my 09 Scion TC. I use a .018 nozzle . I make 250 Dyno'd. I'm happy with it. Never purge into the engine, unless it's at 4k rpm. Keep it floored when you hit it .Don't hit until 3800rpm. Don't let it touch red line, and you'll be fine. Stay under 100shot for stock internals. And don't huff this crap, seems like that needs to be said these days. Sulfer Dioxide is deadly. And again, don't purge a motor, that's not running.
I just assumed the rods gave out from the sudden onset of torque. Looks like a large section of a rod beam shot out of the engine when it blew. lol. But what John Andrade said totally makes sense. I think I'm anticipating the complete teardown and forensic analysis of the engine as much as I am the drag race.
Man…really wanted to see that GLI race. Especially with the F&F graphics on it. When I watched Charles’ video earlier this morning, all I kept hearing in my head was Han Solo saying, “I’ve got a bad feeling about this.” Fun to watch, though. Not sure I’ve ever witnessed such rapid destruction of an engine.
I dont know how i missed this video but that was some of the best carnage i have ever seen. LOL. Never seen that many part numbers flying around all at once.
There were so many things Wrong in this video. LOL Are Honda 2.4l k24a8 engine with my Custom turbo for Woodburn Drag strip in Oregon, with a Wet NOS 50hp shot build in 2014 still running this summer August 2024. Man that let go fast like a un-prepped Honda B16. John was right on everything he said. LOL
Engine masters has a great video on NOS. Though I thought the same thing boosted & NOS compounds as jet charts are based on NA and probably closed ring gap.
well, I learned the difference between a wet shot and dry shot today at least. I don't expect anyone was actually surprised at the outcome of this, I assume y'all have a built motor you were planning to drop in there already?
What you need is a BMW with an M30 in it. Those things have magnificent bottom ends that can pull 500+hp with head studs and stock internals. Forged parts do a lot for a motor!
While I've never played with the happy gas, from reading stories on a (Honda) forum years ago, the boosted guys who shot it started with a VERY small shot and slowly went up from there. For some, ~220 hp on a turbo D series engine with a 35 shot pushed them into the 280 hp range. The engine internals stayed put, and they had a bigger smile on their face.
Honda Tech is fully of nitrous users, heavy nitrous users (200+ hp shot). That is some of the best information on nitrous. So is the SRT-4 forum. Those are two communities that have used nitrous extensively. I had the bottle on my SRT-4 and my Focus ST.
I just finished to watch both videos and the aftermath of that engine was hilarious, nevertheless you guys are professionals and I'm anxious to see how will end this drag race challenge, best of luck
There isn't any air in the lines if there is you have another problem. What is in the lines is gaseous nitrous oxide as heat turns the liquid into gaseous state a purge pushes that out so there is pure liquid nitrous oxide at the solenoid the instant you start to spray . Its simply thete to eliminate performance delay...air 😅
Did you monitor AFR during your runs? Stealing all that fuel from your primary system that if you were still on a stock low pressure pump might have been on running out already could definitely have been what started your problems.
And yes add catastrophic engine failure what happened in my 383 stroker it was a 250 shot it it blew right at the finish line and a car end up running a 10.7 add little over 138mph
the answer is yes it puts a hole in a block, progeresively destroy the engine, how to destroy your engine in seconds, put 100 nos to it and fire it and it will blow it up, hoovies garage would vbe proud
I’m planning to buy either a used low mileage mk7.5 GTI or a used R (2018+ with no more than 50000km) on it and I’m in Canada. I have a 2018 GTI stage 3 is38 overseas and never had a problem with it. How is the reliability of North American R’s? What usually breaks on them? and if they do break, is it cheap to fix or no.
Are we MK5 kids now?
As a result I started vaping.... #vapenation

MAKE A JDM VS. EURO T-SHIRT AND THEN GIVE AWAY A SMALL CHUNK OF INTERNALS WITH EACH PURCHASE! LOL
You mean a small chunk of externals :)
Works as well as it did on Hoovies’ fast and furious Prius!!!

Right up until the dyno part I was all set to buy the kit for my gti omg I was not expecting that
Do it and I'll show you how to do it right. Just ask me, I've had nitrous on all my turbo cars.
I was running nitrous and turbo back in the 90s when people said it wasn't possible to do. Everyone said I was crazy, now look most everybody puts nitrous on forced induction.

How hard can it be.
Expert: this is a bad idea.
Paul and Charles: POWER
Hmmm, a VR6 Scirocco might benefit from a nitrous system, just sayin.
There was a really nasty MK2 GTI that ran a 12V VR6 with nitrous and I'm pretty sure it was running 11s, but that was a long, long time ago and my memory is a bit fuzzy. It was a mint-green colored GTI. I want to say that it was spraying a 150 wet shot?
This car was nice :( I think it deserves another life.

Paul, your sense of humor is second to none
You were both extremely calm during the unplanned dismantling...
Wow that let go quick, that was just an engine self-destruct button.
On the bright side you did make lots of power for a very brief moment. The flame that burns twice as bright burns half as long..
That reminded me of the first (and only time) Hoovie hit the nitrous on his Prius. Fantastic
Nice work boys . Very informative, the compounding effects NO2 along side forced induction .The multiplier effect .
As they say less is more. Great R and D and cheap lessons for the viewer.
Keep up the good work.
This is becoming "The Bad Idea" channel? I never even thought of nitrous on a VW, and I'll probably just enjoy your self-inflicted struggles!
One of the potential video titles was “We installed Nitrous so you don’t have to”
@@Deutscheautoparts underrated comment
Ian was right! Always trust the tuner!
We need a nitrous redemption video

Ok I was not expecting the entire bottom end to explode. WOW.
“Amateurs don’t use nitrous oxide, you’ll blow yourself to pieces.”
God the comments section on this series is nothing but gold. With that said, would love to see you guys try it the not-half-assed way

Back in the Mid 80's I put Nitro in my VW 412. For 3 days it was badass. 3 Days. Then it spontaneously disassembled abruptly. LOL.

My guess is rod as well
If the rod broke then why is the piston broken in half also or did they break at the same time?
There is a guy that says Make questinable choices, you guys just practice the concept. Awesome episode 👍
Bad choice gang
Solid gains in the midrange but fell off up top, totally worth it
Man…really wanted to see that GLI race. Especially with the F&F graphics on it. When I watched Charles’ video earlier this morning, all I kept hearing in my head was Han Solo saying, “I’ve got a bad feeling about this.”

Really? Can I jump into this contest, JDM vs Euro vs American Sport Compact? I got a Cobalt SS that will whoop both your butts.
It's great to see you able to create more content. Especially an explosive episode. Keep up the amazing work and bringing the laughs

we don’t see mk5 gli’s that often. i own one and when i saw this one with nitrous immediately clicked.

This was so much fun to watch! Thank you both for the video!
This video deserves more views
Glad you went for it. Amazing numbers on the final pull
Full send on a 100 shot, wow.
What happens now with the budget and challenge? I had a good feeling about the mk5 too damn
theyre grabbing a B8 audi with a boosted v6 and dsg quattro, and they got the budget reset. but only 5 days to make the bad trans'd audi run
Check out Charles video he covered that there. ruclips.net/video/CR13rFAD6MM/видео.html
So seeing that the mk5 is dead put the nitrous kit on the vr6 scirocco!!!!
I died with the ejecto floor panel🤣😂
Famous last words "I have a lot of faith in bottom end of European engines"
I’ve considered running a “zex safe shot” kit. It’s like a dry 30 shot. On my 1.8t 20v. With your boy Ian’s reflect stage 1 tune. 👍🏼.
Reminds me of when Tyler hoover injected nitrous into a hybrid prius and sent a piston into orbit
well, I learned the difference between a wet shot and dry shot today at least. I don't expect anyone was actually surprised at the outcome of this, I assume y'all have a built motor you were planning to drop in there already?
That certainly made my evening, thank you for that!
Awesome video! Thanks for putting it together. I love the comments about how the internals are now externals! :)
What you need is a BMW with an M30 in it. Those things have magnificent bottom ends that can pull 500+hp with head studs and stock internals. Forged parts do a lot for a motor!
What a plot twist. Glad you guys ended up with an S4 though..
I like the fact there's an ambulance in the background at the shop.
The old adage. Three things can happen and two of them are bad. It was exciting while it lasted.
beautiful man but I think you should have forged everything even the crankshaft and a strong clutch first
Big 5humbs up to the fire extinguisher
Additional benefit of Nitrous that you didn't mention. Much cooler intake charge, allowing additional a/f mixture
While I've never played with the happy gas, from reading stories on a (Honda) forum years ago, the boosted guys who shot it started with a VERY small shot and slowly went up from there.

Without failure there's no succes but i'm glad to see this so i don't have to try it
Can you guys give nitrous another go maybe with the R? Maybe it's a better candidate.
Heartbreaking stuff, sorry to see all your hard work grenade itself.

"Make a bigger boom" yeah.. thats what ya'll did... poor jetta 🤣🤣🤣🤦♀️
What a video to wake up to.
The fastest oil change I've ever seen.
I can say did you get the jets mixed up or use 87oct. Should have used some race gas for that 100 shot.
Guys this was hilarious!! :D For entertainment value alone you've already won.
Loved the video guys, cracked me up! You dudes are funny,informative and entertaining
A blow engine video always wins a lot of views. So you may not have a car to race or spend another 5K on the S4 but you will win fans anyway.
I just finished to watch both videos and the aftermath of that engine was hilarious, nevertheless you guys are professionals and I'm anxious to see how will end this drag race challenge, best of luck
It wasn't about the rings heating up, it happened to quickly. It was that you overpressurised the cylinders before TDC.
That was like putting nos on a melted butterfinger bar. Of course it's gonna go bang
I have seen so many post (before) holes. Never ever seen one blow up ‘live’ lol
Having fun with explosions, I see! I LOVE IT! Idiots installing NOS! I'M IN!

I wish to see a BPG engine if it could take the 100 shot. Only fsi with forged piston iirc
Did you monitor AFR during your runs? Stealing all that fuel from your primary system that if you were still on a stock low pressure pump might have been on running out already could definitely have been what started your problems.
