Is it true that the 04 redline is 8000 rpm ?

Thanks

 

uhm yes... check out the other million post buddy

 

Only on the F22C powered S's.

Some markets (US and possibly others) the engine is enlarged to 2.2 L and the red line reduced to 8000. JDM (and possibly other) are stying at 2L and 9000 rpm.

 

Redline:

8,000 rpm - 2.2 engine
8,800 rpm - 2.0 engine

Fuel cutoff:

8,200 rpm - 2.2 engine
9,000 rpm - 2.0 engine

 

I think your fuel cutoff is backwards...

 

That is odd, based on various sources the general consus around here (previously to the 2.2 release) has always been that the 2.0 has a redline of 9,000 and a fuel cut-off of 9,200-9,3000. I have seen where some early Honda docs said a redline of 8,900 but I never seen it documented as low as 8,800.

 

 

3ngin33r1, is your graph generated from some sort of data logger using ODB-II port? If so, do you know what the sampling rate was when this run to fuel cut-off took place? My guess is that the sampling rate of the ODB-II port and/or the data logger may not be high enough to give an accurate picture of the exact RPM at which fuel cut-off occur.

 

I'll redo the test and hold my RPM just before cutoff to get a better idea, but yes, it's an ODB-II data logger.

 

Fuel cutoff on mine occurs beyond 9.2krpm as logged by a SPA digital rev gauge.
