Spec stage 3+ clutch and lightweight flywheel made it SLOWER!!!

[Jdizzle659]

So I have an 07 mazdaspeed 3 with dp, rp, cat-back, intake, inlet pipe, trans mount, rear engine mount, ap, and now the spec stage 3+ clutch with the fidanza flywheel. My 40-100mph times before the clutch and flywheel installation was at 7.4seconds on my best run before slipping. A bad run i did with the clutch slipping at high boost was 7.8seconds. Now I can't even get close to getting it under 8 seconds. Did 3 runs all above 8.3 seconds. Nothing else on my car is different only the clutch and flywheel. I can't figure out why it would be so much slower... Before doing the runs I had 635 miles on the new clutch. Never got on it during that time so the clutch is broken in properly. Any ideas???

I know some clutches require a 1000 mile break in period, especially for higher stages. Probably a stupid question but, was it cold when you were doing your "runs"? Too cold and you'll get some boost cut.

I'm sure a stage 1 or stage 2 would have been sufficient for your mods.

Was 75 degrees so definitly not too cold. I know stage 1 or 2 would have worked right now, but i'm planning on doing a lot more to my car in the next couple of months.

Should I go easy on it until 1000 miles to see if it needs more break in?

always, there is always a break in period for clutches and flywheels

YEs there is...but it wouldn't affect his times really.

Interesting...I would expect the FLywheel alone to lower your times as it lets the motor spin up quicker which would lead to quicker spool and much less lag.

Hmmm....Interesting to say the least.

you dont need to break in pucks. i know the spec3+ is a disc but just FYI. where are you getting these times from? maybe you are just not used to shifting with the setup yet.

i did break it in.... read the first comment i wrote. i broke it in for over 600 miles

i'm timing it through one gear

Is it normal that the clutch is way louder? Even at idle

Haha, oh yes, the higher the stage, the louder the noise.

 

[madvillian]

does the car feel faster? does it feel better?

 

[Metallic36]

What kind of noise? Is it a whining noise?

pretty sure we had a lightweight flywheel discussion in another thread.. in NA and fi it will allow for a faster rev, however, that's less rotating mass. which is generally what helps spool the turbo.. so you're prolly slower because you're spooling later..

My car has had a whining noise ever since i got the trans mount installed, but the noise i'm talking about isn't whining. I don't really know how to explain what it sounds like. Just loud as ****. You hear everything happening. When you push in the clutch the noise goes away. then you take your foot off the clutch and then it's super loud again

no it moves slower at high rpms while at full boost. Like I'm pulling another car behind me

Maybe the clutch plate isn't aligned correctly with the flywheel?

 

[WTF MATE]

Maybe the throw out bearing isn't in properly.

that clutch probably needs a break in period. Be careful not to burn the clutch when its new as well. stage 3 seems a little aggresive for your mods

i had a stage 3 on my stock lx protege.. lol. didn't make any real noises that i could tell...

anyways, throw out bearing seems probable, especially if they just used your old bearing and didn't put a new one in.. assuming you had a shop do the job.

and that's super weird man.. pull it apart, make sure that everything is torqued down. check for issues on the flywheel/pressure plate.. could be a manufactured defect..
