So, for now I should use the stock flywheel instead of my 9.5 lb current flywheel? I'd rather not dump any money into a flywheel since I'm going to be switching to a automatic in a few months.
Stock flywheel or stay with my current 9.5lb?

i had the steel racing beat one in... accleration was improved in the lower gears. didnt have the problem of the 9lb people where you drop out of band if your not really quick. its really nice for daily driving... also the steel one is better with heat i heard. if anyone wants one i have another racing beat flywheel brand new with all new hardware and counter balence!!! pm me for interest

I'm talking about for drag racing. My car drops out of boost between shift. My car looks like a leap frog jumping up and down between shifts. It's ree-damn-diculous.

You know if you go from a 9.5lb flywheel to a 20.5lb flywheel....your curb weight will go back above 2300lbs.
I ran a Racing Beat lightweight steel flywheel on my T78 RX7 a while back...it was a 17lb flywheel. I would not run a 9lb flywheel on a drag car, aluminum is a better disaptor for heat then steel, but the sacrafice in rotational mass at the center of inertia isn't worth the trade off compared to a heavier steel flywheel. You should just go auto now and not worry about it, why wait a few months. It's still winter and cold, make it happen.

That's when your ET's are going to realy drop. For your set up something around 25lbs is a good start. I've used everything from 40lbs down!![Smilie](https://www.rx7club.com/images/smilies/smile.gif)

I have the 12lb Racing Beat Flywheel... that thing works out great. It's not too light, and it's heavy enough to allow me to go through the RPM range with lots of boost. I had that option or going 9lb, I stuck with Racing Beat (you can buy resurfacing plates for them too which I like)
BTW If you get one new.. RB's website has them for $390, compared to RX7stores $455 (RIP)

I'm going to use the stock flywheel until I put the automatic in.
Anyone want a 9.5 lb SR Motorsports Alluminum flywheel with 4,000 miles on it?

Hey lupe what size of blow off valve are you using. This is just some thing we found on our big turbo cars, we are running 2X 50mm blow off valves and the lag gets a lot better between shifts. Just an Idea to throw around. Ralph

yeah we went to 2 of those. Precision turbo told us that the big tubo applications they recomend 2 each. We did this on our honda with a 71gts and it really made a big difference.
The only thing is, all of us use differen weight flywheels and cluthces so I dont know what the different combonations do, just throwing up some different Ideas. Chrispeed, what is your take on this, am I full of sHxxx?

because of gas these days and since your making your car street legal. that stock flywheel will do wonders. However sacraficing continuous momentum for faster acceleration. i would just keep the lightweight flywheel in exchange for quicker shifts. Just my .02cents.

I have a 12lb, i've considered putting the stock one back in so I can get a better power band on the KAI.

I did this to help maintain rotating mass between shifts and hopefully it will help me yank the wheels
