Default I see alot of people who drag using 8-10 lb flywheels, why?

I have read tons of reviews in the archieves about how lightweight flywheels are bad for drag racing, but yet when I go through alot of builds on here, it is listed in their mods. Most of these people are running 11's and 12's use 9 lb flywheels with good results, but when you look it up and read, your are warned not to use them when drag racing. If this is so then why do these people such as the Trackspeed Integra use a 9lb flywheel and still claim it is a DD vehicle?

Most people bolt things on their cars without understanding why they do or don't need them. It's the "everyone who mods their car seems to have one, so I guess I should too" mentality. You can use whatever flywheel you want on a drag car and it will work and you can still be fast. The general consensus is that a heavier flywheel is better for drag racing because of the extra inertia it generates (compared to a lightweight flywheel) when spining. It's considered to be better for launching especially with slicks and for carrying the engine's momentum into the next gear when you upshift. Some people report the car bogging off the line when launching with slicks and a lightweight flywheel. In the end a good driver can adapt to the car he's in and run fast regardless of what flywheel is in there.

light flywheel = traction control.

Honestly, I cut better times with the lighter flywheel then I am with this stock unit. Dunno why. Not to mention the fact the car revs a good deal slower with the stock unit. I think the lighter flywheel is by far a better choice for obvious reasons.

Likewise...I prefer, and run, light flywheels (mine is 6.5 lbs in the race car, and 8 lbs in my dd civic wagon).

I have never experienced the so called "bog" off the line; better yet, I had "spinning off the line" issues for years. If the name of the game is acceleration, I have a hard time understanding why I should throw on more reciprocating weight!

I also experienced gaster 1/4 times with the lighter flywheel (7.5lb). No bogging either. If you want it to spin off the line, it will, regardless of fw weight. A little spin is good IMO, the fw helps control that.

I'm a pretty captastic 1/4 driver though so take that with a grain.

Modify your clutch case so you can wrap a belt around the remaining part of the flywheel to use as a pull start.

or modify the damper or start it with a impact gun through the damper bolt... that would be something... going back to 1912 and ****. I can even see robert with the cajun accent going on... lol

my motor came with a 10 lb flywheel from the factory.

i agree.

after 1st gear launches, the car is accelerating anyway... why not remove that weight with a lighter flywheel.


as for road racing, faster acceleration/deceleration.

yeah thats why the mclaren F1 LM DOESN'T have a flywheel... because we are morons and we dont know what we are doing installing light flywheels "because we lose something here or something there.. it bogs, it this it that, that only works for drag and not road racing, we dont care mclaren eliminated the flywheel on its track car that won a million races, but no they're stupid and shiet"
