Dinan Single mass flywheel

rmontino · 6th July 2003, 18:03

Like many on this list I had to replace my clutch and flywheel
(11.5k miles). Dinan installed their Stage II flywheel and
accompanying Stage I Engine Software upgrade. The clutch
travels a lot less and engages a lot faster but the noticeable
gear rattle is annoying for normal everyday driving.

I looked for reasons why the gear rattle occurs and found out
that the original dual mass contained springs to dampen the
noise quite a bit. :p :p

But the dual mass also had a torque
limiter to prevent driveline and transmission damage

Under everyday driving this shouldn't be a problem but is this
a concern in quarter mile runs?

Any tips for better run results with the single mass flywheel?

TIA,
rmontino

doesnt dinan offer a stg I flywheel? If so, what conditions made you go with the STg II over the I?

As for driving her...you just need to be careful that you are off the clutch now when giving it full boost as now you have effectivly lost your saftey net in reguards to the transmission.

I am very interested in doing a flywheel but i am hesitant as i do not want the dinan software on my car.

FINALLY!!! someone who has gotten a stage 2 flywheel on the board.. PLEASE post more reviews and comments.. especially about the gear lash noise at idle... if you could, I would love to have a sound clip to see how bad it is...
Thanks!!!

The MKIV Toyota Supra Turbo also has a dual-mass flywheel from the factory which people often replace with a lighter, single mass one(as I have). My TRD setup can rattle quite a bit when the car is idling low, but it's my race-prepped street car so it doesn't bother me one bit. If it were on my M5, I don't know if I'd like it then.

As for your question regarding the "torque limiter", I'm not sure what you are referring to. Who told you about this torque limiter?

Hey Tri,

Optimum A/F is as best you can get. Most other things are self adapting. Its just great marketing by Dinan. Its upselling. If you buy this, you must buy that as well.

Powerchip will handle every single Dinan Upgrade. I intend to prove this.

If Dinan will sell me the parts.

They wouldn't sell me the MAFS . They were saying it wouldn't do anything without their CAI. Next time I try, I'll but all 3, Mafs,CAI & Upgrade. Surely they'll let me have that together, but they will insist that it needs their software, so I'll have to give them a disclaimer to say I won't hold them to the promised power as I won't be running their software.

I would be willing to do this as I believe I will get more gains without their restrictive, out dated software.

TIA, What brand Clutch did you go with? and How much Coin.

MIB,

I mentioned the fact that Dinan wouldn't sell you MAF's without the CAI to my BMW Master Tech (authorized Dinan dealer) and he said he'll get you and anyone else wants Dinan products and have it sent straight to your door. He's a great guy and knows his stuff. He's the only BMW tech I have work on my car.

PM me if your interested.

Thanks TRI & Lupo, I'll let you know.

I think there were two main reasons why they didn't want to sell it to me.

1. With the Wheels and Strut braces, it came to 8 Points so I said rather than go to all the trouble of trying to prove prior purchases, just sell me the MAFS as they are the extra 2 points to get the Badge. I don't think they were overly impressed with that. But at that stage I wanted the AA CAI.

Now that Steve (X-ray's) tests seem to indicate that there is more than meets the eye with the Dinan Combo, I really actually want it.

2. They are hesitant to ship power mods overseas. Especially to RHD vehicles.

But I think the only real problem is the headers won't fit. Most everything else appears the same.

Looking closely at the AA, I'm thinking of hooking that up as well for Breaks but the intake part would point straight at the Dinan CAI.

That way the Dinan filter is getting headon air blowmn at it front on from the Dinan Foglight Upgrade and also air from the side blow on it from the AA . The two ram airs are about 90 degrees to each other.
(I would not use the hoses supplied with the AA Kit, if that expalins it better).

If I order all 3 together, I can't see they could have a problem, other than the fact they want me to buy their software, which is not going to happen. (Unless they upgrade it to the powerchip software, and re package it.)

tfung,

I got a couple mp3's of the gear rattle. The Forum rules
say attachments are allowed. The FAQ says there should be
a "Browse" button but it's not there.

Is there's a vb code to attach an mp3 file?
Else, you can email me and I'll send you the mp3's.

Thanks,
Ram

Hey Ram,

I sent you an email. I'd like to hear the Mp3 as well.
