Unfortunately using flatshift is a bit harder on the clutch, which caused it to slip. It was only a 12.69 @ 126mph, but, for reference the 100-200km/h was only 6.71 on that run, so it's basically a throw away. The car should have no issue breaking the 130mph barrier in the quarter assuming the clutch holds on.

@@TheJohnb35711 Most likely yes, but I've had it slip a couple times even just rolling into full boost at mid RPM. I believe the torque rating it 510lb-ft, and if that's at the crank, the motor is producing slightly more than that. I'm thinking about just upgrading the pressure plate

On the last pull you can clearly hear increased noise on 4th gear. I don't think it is rod knock, more like main bearing knock (I had one failed me last year and it was similar noise). It may be also piston slap but I'm more on the main bearing problem. Funny think is that when main bearing spoon oil pressure dropped only by a little... Till the end I was hoping it will be simple fix 😔

If his main bearings were gone, he'd have little to no oil pressure. He does have upgraded oil pump and if it's shimmed, putting out more oil pressure flow/psi than factory then maybe he'd still have some oil pressure but you'd still see a noticeable change. It would likely be half as much as before or worst.

A couple weeks ago I was doing pulls when I lost a bit of power and my exhaust got louder. I figured the downpipe vband got loose from the heat. I tightened it, but the power loss and noise didn't go away. Checked everything I could, compression, oil, timing, ect and second guessing myself on all of it. I was racking my head trying to figure it out until I happened to notice a bolt was missing off the back of my turbo. I have a ebay special t3/t4 internal waste gate with the 5-bolt pattern that turns into a 3" v-band. Apparently when they drilled the bolt holes, they went all the way through the housing. The bolt must've gotten hot and fell out which allowed the exhaust to bypass the turbine and the O2 sensor to misread. One trip to Ace Hardware and everything was back to normal. It doesn't sound like that's your problem, but here's to hoping your issue is an uncommon stupid simple to fix too.

The way we used to diagnose rod knock was while the engine is running pull a plug wire on each cylinder and see of the noise gets quieter. Obviously you would cycle this if you don't hear it change, and it'll be a little different since you have COP. But perhaps you can just kill each cylinder via the tuner.

The worst things always happen to the best people! Great explanation in the video for each diagnostic test you did and why. To me, like some others have said, sounds like main bearings or crank walk. It gives a very similar sound to rod knock, but obviously every test you've done has exhausted that possibility. The only way I know to test for main bearings is by taking everything apart and visually inspecting them unfortunately. Every video that comes out with the red car is always exciting. Seeing this car progress over the years really brings me, and I'm sure a lot of other people motivation. Keep up the great work, keep your head up, and keep the amazing content coming. Sometimes the best things you can do is walk away from something, sleep on it, and start again with a clear mind.

The crankshaft was eating through the piston and almost made it through to the wrist pin.

Which sometimes fail after thousands of miles, as that was a usual issue with them and it was luck of the draw. If the pump is good and still pumping oil everywhere.... Drain your oil check for metal shavings.... my moneys on thrust bearing if it's not an oil starved engine.

Quick question. Why are you running Copper AKA Nickel plugs? Iridium and now Ruthenium are better for performance in every metric AFAIK. Even Platinum have benefits over Nickel. I know there can be good reasons and of course there is a price difference, but Nickel plugs are essentially old tech. Big bummer about the engine! Doesn't really sound rod knockey. Only other thing I can think of is maybe a wrist pin issue? Not even sure when or how those happen, but hey just tossing something out there. Possibly a piston skirt damaged so you are getting piston slap? Hope it's nothing too bad!

Next up I'd check out your oil pump. Since to say the sound is coming from near the nose of the crank. There's also main bearings like others have been saying

What about a crank bearing ? It doesn’t have to be 100% a rod bearing. Not a Mazda man but could you see the bearings if you drop the pan ?

I think it may be the pilot bearing. Since it was not really pressed fit, it may have grenaded.

I think you're referring to my old twin disc setup where the pilot bearing didn't fit right. Fortunately that is long gone and the current setup does not have that issue

If it does turn out to be crank walk or main bearing (which I don't think it's main bearing bcuz you didn't have a permanent drop in oil pressure afterwards, or did you) then I'm going to say the cause of either of those failures would be likely due to using ARP main studs without re-checking the main bearing clearences. The arp head studs recommend getting the mains line bored afterwards. But if you check the factory specs with OEM main studs and then make sure they're the same clearences after torquing the ARP's then you might not need a line bore.

Could it be the front crank bearing ? Or the fluid damper that seen better days and Is throwing the crank out of balance?

I have a 1.6 that I’d be willing to sell ya! In all seriousness though, that sucks. Can I put an idea in your head? Jaguar V6 swap from Rocketeer….first build in the US…this would be revolutionary for us tiny car guys and I’m sure you’d make incredible content on it.

Wondering if the crank could have warped/moved enough to maybe spin or damage a main bearing? Maybe a main could’ve been compromised by dropping a thrust bearing? Maybe it’s as “simple” as a chipped oil pump gear. Anything’s possible I guess

Disconnect the accessory belts and run it to see if it's something with those. Any debris in the oil/inside the oil filter?

Agreed. The worst is at startup when the oil pressure has not developed. A lot of people start in neutral with the clutch engaged to prevent this. This requires that the clutch switch be defeated in some way.

After fully disassembling mine, I don't know why people say they're impossible to put back together. And I'm not trying to sound like some kind of pro, the parts are very simple, nothing spring loaded/pre loaded, etc. I will definitely make a video on it!

I believe when shifted in fourth, the noise could already be heard..any sign of overboost in logs? If oil press is all good, maybe rod bent, or crankshaft play/thrust bearing issue. Once had a case of a broken thrust bearing (don't remember what car) removed serpentine belt, stuck a pry bar behind harmonic balancer and there was movement. Removing oil pan would tell more either way..

Some good points, but I just want to point out if a rod was bent you'd lose some compression In the affected cylinder
@blackinblue11

@@miatamadness9535 I see what you mean, there are many cases of bent rod, but the piston is very slightly lower for it to care, so the engine starts and runs fine with normal oil press, except for the noise. In my case the small end of a rod was kissing the crank.. Should add my rod did not bend to banana shape, but to the side, like small end was offset to big end, if that makes sense (eng. not my mother language)
