Thread: Lightweight or heavy flywheel

If your rpm are dropping between performance-oriented shifts you need to turn in your tuner card right now.

maybe on the highway if ur shifting like an old lady(like i do), otherwise when i get on it, there is little to no loss....

I <3 my fidanza, on my DE and VE(as soon as shes up and running)

how much power are u making?? DE or VE

I was referring to the rpm drop when the clutch disengages and reengages... this is the loss I am referring to matter of fact wasn't there a thread that showed rpm loss during shifts for each gear specific to gear ratio? I can't find it other wise I would post the link up. My question sort of applies to that thread.

That "rpm drop" doesn't change with the weight of the flywheel.

I have a stock flywheel on my turbo car. I was told by an sr20 guru and long time friend of mine that when launching at the track a heavier flywheel will have more inertia and will help you to get off the line. However, I feel that even with a lightweight flywheel if you are a good enough driver you should be able to transfer the power fairly well.

the rpm should drop faster once the clutch is disengauged though

That's true. I recently upgraded to a lightweight flywheel. My first one. I always pretty much waited enough time between shifts on the stock flywheel anyways to not notice any difference in driving. I just let the RPM drop then rev-match into the next gear. I shift like an old grandpa during casual driving.

I thought he was talking about the "rpm drop" you experience when you up shift from one gear to the next. Meaning the clutch is engaged in say 3rd gear then you up shift to 4th gear and reengage the clutch. There is a drop in rpm. That's what I thought he was talking about, since he brought up shifting gears and all.

I see now that was a crazy assumption. =/

From the way he worded it, I thought the same Ben.

You never take your motor over 2000rpms. I heard you went over 20 mph the other day.
