Mysterious big loss of power/drive on Spa circuit during parade laps.🤔

[NSXGB]

He said it was "initialised" properly when fitted...

'initialising' is the procedure to set up the twin plate clutch, I don't think you can get the car in gear if that is not done. If the clutch pedal didn't have quite enough play, when the fluid in the system expands, there is not enough 'slack' and will be like the driver is pushing the clutch pedal slightly. My total guess is that may be the case here, normal driving would appear ok but at higher revs it cannot cope.

Yep I understand what your saying but does clutch fluid do that? That's the same as the brakes coming on on their own then.. Usually it's the opposite and fade so less "force" from the fluid...

Maybe it's the "battery" scenario? They sold him his old clutch again ������

That would be really odd indeed.

But it has happened.

I guess brake and clutch circuits are different. It happened to mine after NW replaced my clutch. Drove about 10 miles fine then clutch started slipping over 4000 revs. Let the car cool down a little bit and it was fine for a mile or so then started again. Back at NW they adjusted the pedal and all has been fine ever since.
Just a suggestion which would be free to check. Sounds like my scenario just not as extreme.

I'll wait for Pride to answer the questions from the others.

In the meantime, several owners experienced the same issue as NSXGB mentioned due to the lack of free play at the CL pedal/master cyl.

This is what's happening;

As mentioned by others, I don't know what 'jumped' and 'revs rushed up' mean….

About 6,000rpm is when the VTEC kicks in but then earlier in the post, he was referring to 6,500 - 7,000rpm so two different stories….

VVIS opens at much earlier stage (about 4,800rpm).....



Popcorn time….

Ok, did not expect this, quite weird. If OEM parts are being used there's no need to adjust except initializing the clutch.

While it happened in your case did you fell a sudden jump? I guess no.

Nope, the sudden jump has got me miffed too. Mine was a gradual affair.

Just remember Senna was driving that day.....

My first thoughts were same as Jonathan's - clutch-slip. But I'm surprised it happened there, as I thought peak torque was lower down.

Need more detail from Clive first...
