I have a 9 lb flywheel and I lose alot of boost/rpm between shifts. What is a good weight flywheel to help with this?

I'm eventually swapping to a automatic to prevent this but I need something to tide me over until then. I'm thinking just use the stock flywheel?

 

I would think the stock flywheel would work better because of greater mass. That would keep the momentum of the engine rpm high while the tranny is in between shifts. It is definitly harder to stop a semi-truck than a crx due to mass and speed.

I also have a nine pound flywheel, I did feel a signifigance amount of acceleration at lower rpm with, but at higher speed and rpms, it didn't feel any different than the stock unit.

 

a 12lbs flywheel might be a good medium????

 

anyone know how much the stock 3rd gen flywheel weighs?

 

i believe its 18lbs maybe 22

 

23 Pounds?

 

sounds right

 

no the FC was 22lbs and the FD is 19lbs i was kinda right just quoted both hahaha

 

Okay, so what's the best weight to keep the rpms/boost up between shifts?

 

lupe maybe if you have the money try a 12lbs flywheel or trade your 9 for a 12

 

do you \"power shift?\"

 

is the 9lbs taking you out of your powerband between shifts?

I think the Racing Beat Flywheel is the best of both worlds....and it comes with a counterbalancer, balanced with the flywheel

I vote just learn how to shift faster whats the point of all that power if you can't drive.... nah, JK. I have heard mixed reviews flywheels. Some say the best flywheel for drag racing is the stock one, and others say a lightweight one is better. The problem with the stock one, it is substantially more heavy than the lightweight one. This means, you will accelerate slower. But if you are losing that much rpm between shifts maybe its better for you. If you got the money to spare, just experiment and try the stock one, see what happens. Im assuming you do the work on your car yourself, so if it turns out to be a bust, all you are losing is your time, and the few dollars that it costs for a stock one (unless you have one on hand).

 

I have a stock one in excellent shape if anyone needs one

 

The stock FD flywheel is 20.5lb. Keep in mind that if you are quoting aftermarket flywheel weights, you need to factor in the counterweight as well, which is 4lb. So a 9lb flywheel is actually 13lb, and a 12lb is actually 16.

I run a act streetlite 12lb and am happy with it. IT is just as driveable as the stocker.

One thing though...maybe I was up too late, but I swear when I watched your video (on offtopic, might I add) it sounded like automatic to me?

 

That was just steve letting out of the throttle and then getting back into it. He got scared for a second

 

lol

 

Your flywheel weight would also depend on your clutch setup. A lot of people don't factor that in.
So what clutch are you using?

 

Just using a ACT 6puck unsprung.

 

I'm also using the ACT 6 puck unsprung with the ACT 9# flywheel. Its hella tricky driving up inclines! I'm wondering how long the unsprung 6 pucks last. I know it depends on driving habits. I was told by several rotary tuners (Rx7.com, Marvel Speed, etc) that this combo works very well for high HP setups.

 

I ran a 6 puck unspring with a racing beat alum flywheel and it was a good combo but i switched to a cintered iron disc and it was brutal to drive.. i then switched to the stock flywheel again and it made a nice driving difference and the stock flywheel made launching the car much better. It helped bc the stored energy you have from the extra weight of the flywheel..makes a worthwhile difference.

 

If you lighten the standard flywheel, what do you have to do with the counterweights???

I was going to buy a lightened flywheel but might just lighten the standard one a bit. But i was a bit confused what to do with the counter weights. Do they need to be lightened aswell??

 

Not quite the same.... the counter weight on the stock flywheel is on the outer edge of the flywheel. Aftermarket ones are toward the center. Centrifical forces are different between the two. Stock one will have more inertial even if it has the same weight
