Is this normal for a 6sp?
I just got out of the 1000 mile break in period and finally got a chance to "get on" the gas on my new Max.
Here's the thing, when I am accelerating fast and take my foot off the gas to engage the clutch, the engine seems to hold the rev for a second rather then going down like every other car I ever owned.
Is this normal? It's really not a problem when I'm driving slow because the revs will go back down by the time I release the clutch. However, when I'm going fast I find myself waiting for the revs to come down before I release the clutch in fear that I'm going to do some damage.
Has anyone else had this? Is this normal or what?
Thanks.

It happens in my 6sp, too.
IIRC, it IS emissions related (I'm pretty sure)
Suddenly dropping throttle does something that catalysts don't like, I think. The emissions control lets the throttle off slowly enough to prevent that. (I'm less sure that this is correct.)

I am not exactly sure but here is my theory. A larger displacement engine w/ more cylinders tends to be harder for the Ravving to drop. Because there is more momentum in the motions "UP and Down" within the cylinders. Also VQ35DE has aluminum light weight pistons, which makes this engine a "high ravving"(For a 3.5L)engine. So its OK for the engine to ravv as long as its not nitting the Redline too often.
Example,
Integra 1.8L 4 cylinder will drop more quickly from 5000RPM if you let the gas pedal off, Than comepare to a DODGE VIPER w/ 8.0L V10 which will come down more slowly because there is more momentum within the pistons.
Again, this is just my theory I could be wrong but I thought I might give it a shot.

It is emissions related, not anything to
do with heavy flywheels, etc....otherwise you would see the same effect revving up as well.
The Max has a damper on the throttle (mechanical on the old Maxes, electronically contolled by the ECU on the newer Maxes) that drops RPMs/throttle gradually to avoid over-enrichening the mixture for the longevity of the pre-cats.
nuthin u can do about it on the new Maxes....

Its the weight of the flywheel - possibly for emissions reasons. My friend has an M3 and his was the same way. He just installed a lightweight flywheel and now the RPM's just drop immediately. He said it actually hurt his 1/4 mile times because the engine doesn't hold RPM's anymore. I'd also think that if the rpm's are constantly dropping rapidly that it could do some damage over time.

I'll say it again..it's not the flywheel..if it was
the flywheel you would see the same effect if you blipped the engine in neutral and if you do that you'll see that the VQs have among the lowest 'flywheel effects' of any other engine in the world
Your friends' experience with the M3 has nothing to do with the Maxes issue which is controled by the throttle....I know because I've had Bimmers..I know how they work, this 'slowed throttle retard' on the Maxes is not found on the Bimmer

Read this sentence.
It's part of the emissions controls.
Now read that again, for comprehension.
It did this on an '85 Toyota Tercel!
Some cars it's mechanical, some it's electronic, but it's for emissions. Sudden throttle chop makes for overrich mixture (briefly) which sends out unburned hydrocarbons. I think that it also reduces the life of the catalytic converter, but I'm not sure.
