Seriously, drive over to Scott's. Give him cash. Go to Ace hardware with him, and he will build you a better bracket.

 

This means nothing, but I saw it and thought of your magnificent car:

 

It's wonderful.


Nothing new to report, clutch will be next week. I'm about to ease off and swap to winter tires soon and put the car up for some work. Bought myself a QuickJack 3500slx and hope to redo some wires and create ducting over the winter. I have a credit roll over for Summit Point that I need to use next year. Start breaking parts.

 

HALP!
Hey Twin Disk users, quick question.... I know light weight flywheels have a bunch of noise associated but I just picked my car up after having the clutch swapped out and it rumbles on decel, partial throttle. Normal?

I am going to park the car for the rest of the week and check to make sure the driveshaft/diff bolts are snugged....then check PPF alignment. It goes away with the clutch pedal in. But at highway speed when feathering the throttle it'll feels and sound like I'm driving over rumble strips.



One year old slipping Flyin Miata Happy Meal Level 2:

 

Is it just one clunk or multiple?

 

Not even a clunk. You know when you start driving off the road and hit rumble strips. That's what it feels like. ONLY when decel with partial throttle.

NOT under load
NOT when full decel without throttle input
NOT when clutch is depressed in
NOT when idling
NOT when driving at slow speed, only noticed on highway

 

That flywheel has seen better days.

 

Yes but overall that clutch still has tons of life on it, which means it was simply overpowered and not defective or worn

as for your other question: seems like something is wrong. the twin disks I've driven are loud, chattery, and very unfriendly, but I never heard or felt vibrations like you're describing. Dunno

 

Yea, competition clutch recommended changing the disk at 0.23", there was plenty of life left. It's no longer in warranty, Flyin Miata popcorned me to Competition Clutch directly and I'll be sending it in for them to assess. If they just agree that it was overpowered, then I doubt I have any option of reimbursement or replacement, partial or otherwise.

It's just funny because it was mentioned FM used in on an in house 450whp car without issues, along with TNTUBA having used it for two seasons and that's some hard launching abuse. I expected to break my trans before slipping the clutch.

Driving home on the twin disk wasn't that bad. It's engagement after the adjustment protocol feels a bit higher than im used to, and it's as though it's fully disengaged by 1/3 pedal depression. It didn't chatter as bad as my old Stage 4 6puck competition clutch which was a nightmare.

 

The place that installed the clutch offered to tow it, diagnose and repair whatever the issue may be at no charge. I'll update Saturday.

 

That's service right there.

 

It is shorter pedal travel. You can add a pedal stopper so it doesn't have to travel the whole way.

 

Just FYI - if you end up deciding the twin disk is too light 949 has a 12.7 lb "street" replacement flywheel they sell for them now. I haven't seen anyone mention it on here before (might have just missed it) but noticed it on their site. I've got a twin disk also but motor is out and probably won't get to try it out till spring.

Replacement flywheel for SuperMiata 7.25" Race Clutch

 

I actually had seen that, and didn't know if it could be subbed out. Does one have to buy the clutch, then the additional flywheel? It still felt great. More affirmative pedal effort, but modulating was fine and not any worse than the FM2 in terms of drivability. It is loads better than the CC Stage 4 sprung 6 puck I first had. I hate that clutch so bad. I was shocked to find out that FM and 949 sources their products from them; but in the end consider me swayed as they've been great.

 

All set, they rotated the driveshaft to diff flange, checked the PPF alignment and it's all sorted.
Snow tires on and will just chug away this season in either the Mazda 3 and some light duty miata time to break the clutch in.

I have a new VVT head freshly built, tomei cams, and SUB. Debating if it's even worth putting on this block as I want to enjoy the tune that's on it, or just to build a side motor. Or sell.
The Flyin' Miata Level 2 clutch has been shipped back to Competition Clutch for diagnosis.

My Supermiata crossflow has a leak somewhere. I noticed coolant pooling up by the fins/end tank on the lower passenger side. Break that down and figure out why, maybe see if it's able to repaired.

 

Did I miss something? Why are you messing with a new head?

 

+1 for side motor #ALLOFIT build

 

The head project started earlier this year. Got a vvt head for $125 and just slowly collected parts. Shim under bucket conversion became troublesome with the extended valve length so it took a while for me to justify Tomei cams.

 

He has a disease. Like the rest of us

 

Yea, the addiction is too real to the point that I'm tempted to simply sell the head and call it done. Anything more and I'm looking stickier tires and wider wheels which means body work. Avoid.

I'm helping my boss with his factory five stuff now. He gutted a subie wagon and needs help refreshing the motor.
