If this engine has been on the rig it will have done many many km's. So, I don't see how it would be missed except under conditions the rig can't replicate.

In that case....what?

Taki Inoue mode:

If it means what I think it means...we were kind of right all along. The firing order they're using is shaking the engine to bits. Too much harmonic frequency at certain rpms.

The power and reliability is there, IF they can make the engine last through the destructive resonance. Maybe they tried a oil pressure based hydraulic damper on the crank as a quick fix.

I think these failures aren't really failures but Honda just trying 5 different blocks to see which one will handle what they're trying to throw at it.

Ha. New crankshaft and cams would be too easy to change the firing order.

The vibrations affecting them is actually affecting the injectors i think.
TJI itself would not cause any more vibrations than standard injection. Would actually be less! Because combustion is more uniform.. But i feel these new "Honda injectors" yes... Could the be crazy enough to make their own? ! OK matbe not. Probably Denso.
Whatever they are they could be very succesptible to vibrations. Clattering of pintle perhaps?

We know a cylinder is a cylinder. Valves are valves. That leaves the piston crown and the injector.. I think those are where the problems are.

So you know, for a fact, that NO ONE has tested full power map settings? I understand that the mere arm chair specialists that we are enjoy putting our 2 cents in, but we should not make up 'facts'.

We simply do not know what maps and fuel loads teams are running. Most often, teams will hold back performance until it actually matters - Qualifying and the Race. That's another thing Honda will be behind on - Mapping the ICE and other PU parts.

This is exactly it, we don't know. Not to say that someone here doesn't know, but their tone would come across as them having a source or is one.

As for my armchair specialist take, not fact, I think it's fairly safe to say that they have the full power map on the car multiple times. They may not do an entire lap pushing the PU, but at least for a straight or two and the odd corner, they will be testing drivability of the map. I highly doubt they show up to Melbourne, cross their fingers, and turn up the wick hoping the map checks out.

I feel so bad for Honda and McLaren. If they do find success, this will all add to the story. Hours away from another day.

Wazari can you please step in and throw few clues ? i hardly believe in reports coming from AMUS etc.

Remember none of these are even firing engines, there's going to be at least one big bang in there maybe more. Getting all those bangs to not have harmonic resonance at critical RPM is not so easy to do.

I'd say they're as accurate as anything he could realistically give you.

in his last post he mentioned about quite optimistic mood in sakura and honda was quite upbeat despite setbacks.
i do not believe mclaren-honda are orchestrating drama and gonna come out and surprise. not paying attention to vibrations (with TJI ) is primitive mistake. i do not believe Honda can commit this basic mistake when they are introducing this tech after every other manufacturer and after 2 years in business.

As someone who is new to the forum, has there been any proof that shows he is who he claims to be?

More I read, more it makes me feel like everyone here has been catfished especially after last weeks comments.

There is something that Honda would like to hide. All the official info from Honda appear to be smoke screens to me. Even though the prospect is looking dim right now, I still admire the Honda management for having the guts to stick to their game plan.

The end of the tunnel cannot be too far away....

German SportBild too reports the Problems lie in the Cylinder Head, specifically with the new Injection Technology. That supposedly was the cause for the Day 2 and Day 5 Engine Failure.

Wasn't yesterday's "failure" an electric issue and they changed it as a precautionary measure?

I am looking forward to the comment from insider "Wazari" when the test action is already over and he can post another entry, with facts that have been published already somewhere else.

I wonder if the 2016 PU could fit the new McLaren, and whether it would be a better bet for the first few races. Hold off the 2017 PU until it is reliable, an introduce it in Spain.

Hi guys,

Long time reader - First time poster.
I love this forum. I am a honda fan and love formula 1 and this board since 2014 has kept me sane with the new engines. The conversations are great.

I recorded this yesterday at the test day, Listen to the rasp clang sound when stoffel changes gear on the straight. Only car to do this. Sounds like the gearbox being hammered. What do you guys think ?
