newbie question here
what is the VTEC switchover RPM on the 04's ??? is it the same as the pre 04's S2000?? i know i feel a noticeble sudden kick around 7k rpm+ somewhere there .. im just curious whats the exact RPM vtec engaement... thanks


peace.

 

I'm pretty sure it's 6200 rpms, about 500 lower from the previous models.

 

~6K

 

About 6000 (which is exactly the same as the previous ones.)

Where do you live? High altitudes can sometimes cause the switchover to migrate to a higher rpm.

 

It's ~ 6,000 for all model years. The 04-05's lost VTEC rpm's because of the lowering of the redline.

 

I stand corrected. Thanks.

 

2000-2005 Vtec engaging at 6k unless u mess with VAFC

 

I sold my MY00 about two years ago and purchased a MY05 last week. I took a road trip and just got done with the break-in period.

Question:

In my MY00, the 1-2 shift (if performed at redline) brought the revs back to ~6000 RPM, i.e. in the VTEC part of the powerband.

In my MY05, it seems that the 1-2 shift (also performed at redline)brings the revs back to ~5500, i.e. not in the VTEC part of the power band.

What's up with this? Is there really a "dead spot" in the power band between first and second gears?

 

No. With the clutch delay valve, the clutch slips enough that you stay in VTEC.

Without the clutch delay valve, I understand the rear wheels slip enough that you stay in VTEC.

I believe, though, that the engine electronics have been changed so that if you are at part throttle, VTEC may not engage until a higher RPM, if at all.

 

Shift just slow enough however, and yes you will encounter that "dead spot" before VTEC engages on the 1->2 shift.
