Flywheel mod - Honda Prelude Forum

Si_g · 11-17-2003, 06:14 PM

I ve been looking into upgrading my flywheel to a lightweight one. i m hesitatin between fidanza and ACT. If anyone has done the mod with anykinda of flywheel, please comment on the difference, if it helped a lot, and do you recommend it. Anything else is welcomed. thx

I have a JUN lightweight, and it's great for blipping the throttle for rev matching and what not, just be weary that a lighter flywheel will decrease your 1/4 times.

Dosnt everyone want to decrease their 1/4 mile times?

I was wondering the same thing but I guess he probably means that your time will increase.

My friend has a Fidanza on his h22a accord and the starter has trouble catching it. I've had my clutchmasters flyhweel for a little over a year now. I've had no problems, starter catches every time. You'll notice a large difference in acceleration/revving. While your transmission is out, double check your clutch, may be time to replace that as well.

sorry, I meant that you'll go slower down the 1/4, because your motor won't be holding momentum as well, to carry more power into the next leading gear

hey prelude styl, i see you run a 15.3 ! i ve never ran my ***** (93 H23) at the track, but a 15.3 is what i expect it to run. i seen lots mild moded 5th gens run 15.8 and 16s and i beat some on the street. what engine mods do you have ? i have cai, headers, highflow cat, catback, extra resonator, msd ignition, msd coil, wires, and iridium plugs

oh and JDM Mike, clutch is bout 5 to 6 months old, i replaced it with a exedy clutch. those are pretty much stock. so i think it can handle it. but yea, i ll make sure to check it, i hope i can get more feed back b4 i order it.

So far i seen ACT for 255 and fidanza for 239. if u got a name and a price, please post. thx.

Hey, just installed a Fidanza in my car this past weekend, definately noticed a difference. I also upgraded to an Exedy racing clutch at the same time..... Everyone says it takes a while to get used to, it does, took me about 10 minutes. The car feels much more responsive. I really don't think that it will increase your 1/4 mile time seeing how Honda installed a lighter clutch/flywheel combo in the 04 Civic Type R and it dropped the 0-60 time from 6.8 to 6.6, I know that's just 0.2 seconds but....

go pre · 11-18-2003, 03:50 PM

why would the 0-60 time would go down and not the 1/4? do you understand that a "decrease" in time means you went faster?

prelude styl · 11-18-2003, 05:03 PM

it's known that lighter flywheels slow your 1/4 mile times, that's not what they're meant for.

Si_g, I have intake/half a header/exhaust, and rod knock. There was always something wrong with it, wasn't sure what, but after going to the track most recently, I now have rod knock, so that's what's been wrong with it.

Si_g · 11-18-2003, 07:12 PM

Tight work. I just talked to a few people at school, one of them told me that it was known that installin a lightweight fw would kinda disturb the idle of the car! So for you guys who have one, did you notice any idling changes, even is very small ? The guy said it was bearly noticable on his car, so let me kno ight.

thx

prelude styl · 11-18-2003, 08:50 PM

I didn't notice any idling difference

bsi · 11-18-2003, 10:01 PM

i noticed no idling difference.. and i have a fidanza. as for the starter not catching- that problem has been fixed (hasnt affected me at least)

luder94si · 11-19-2003, 08:06 AM

No idling difference here...I have the clutchmasters (same as the fidanza)...no problems with starter...It's a good mod if you have to change your clutch, but if your clutch is in good shape & doesn't need to be removed, you might be better off spending the money elsewhere....

Si_g · 11-19-2003, 08:52 AM

ok thats good to kno. everyone seems to have the fidanza or clutchmasters. Is there anyone that can comment about the ACT?

bsi · 11-19-2003, 06:12 PM

i looked into the ACT but it is really hard to find since it is brand spanking new... plus there was a groupbuy on the fidanza

PRelude787 · 11-19-2003, 09:05 PM

I've got a Fidanza as well.....it does take lots of getting used too. I noticed no idle difference whatsoever. And at first my car wouldn't start for isht!!!!! I had to push start it once down my driveway just to get to work. After that one time.....it never did it again!

if its known then why didnt i know that?

is this really true? have other people who have done this mod seen similar results(slower 1/4 times)?

7) Lightened Flywheel

We can exchange your stock flywheel for one that has been lightened by as much as 4 lbs
A lightened flywheel reduces the engine rotational mass, and lets the engine rev faster
We have run 60' times in the 1.50's with a lightened flywheel

Those guys know what they talking about. This was very clear ryan, thx. So if i get this right when the last one says this
"The benefits decrease in higher gears in proportion to whatever the ratio is.", does it mean that the higher in gears you are, the slower the acceleration will be ? I mean, is it that noticeable ?

PS: ryan, ur comin to daytona saturday right ? if yea, if u wanna drive with us, we meetin up at 1030 sat morning at the 7-11 on orange and 50, and leavin at 11 sharp.
