Anyone with the Steel SMFW and Spec 2+ setup know if the stutter getting into first and or reverse dies down after the 500/600 mile break-in period? I guess the same question goes for the chatter although I can certainly live with it if this is the worst it gets.

It does not go away until the clutch warms up. It will always take more gas to engage the spec clutch than oem clutch.

Chatter also doesn't get better. Turn off the ac to get less chatter.

Figured - and figured. Thanks man. The modified CDV that you have worth looking into? How about the DV's?

Modified CDC is worth it for 2nd gear engagement.

You need upgraded DVs if you are running 15+ pds boost

Check out Terry Burger's write up on Forge DV's before you take that dive. I've been running 17+ psi on stock DV's without an issue.

Does the upgraded clutch really better than oem? And did you upgraded because your started to slip or just to upgrade?

I have the Spec stage 2+ w/ steel SMFW for about 2000 miles. The engagement does get smoother over time. I don't even notice it anymore, but in general it want's to be engaged quicker than stock so slipping it really slow from a stop may always give some amount of stutter. If you commit to taking off and give it enough gas though it feels great. I upgraded at 60K miles because stock clutch was slipping with FBO, E85 and meth. The chatter will always be there, nothing you can do about that. Overall I've been very happy with the clutch and flywheel. It's solid.

Thank you very much for the info, i will try e85 maps next 2 weeks so i'll see if i need an upgrade.

how much power your car produces on such a setup? 1/4 time?

I am in the 804 (RVA) if you want to ride in a ST (with Spec 2+ & steel SMFW)

Although, I am moving to Atlanta in 2 weeks.

Sure thing. Planning on moving in July 15... so I should be free a couple days after that when I get settled.

I was about to be mad because I was in Richmond and looking for someone who had an upgraded clutch/flywheel.. but I am also moving to ATL, just on the 8th haha

I may be reaching out to you in the near future if your offer to see the car carries through a couple states to Atlanta..

Haha sure thing. Sorry for the

Mine doesn't usually gear chatter (or rattle) when cold and I usually don't notice it at all unless I have my AC on (which I don't hear with my windows up).

On the flip side there are times when I start the car and do hear it...

As for clutch chatter during engagement, it only really happens with slow engagement in 1st/reverse. Even when it does, it's not loud at all.

Lastly, the clutch definitely got better after the first 1000 miles.

Never dyno'd, haven't been to strip in awhile

Hitting 20psi pre-5k, car is fast and responsive.

May be you've raced some fast cars? Just to compare the level of power your car is producing.

Unfortunately his thread on Forge DV doesn't account for those individuals with stock DV's that are leaking

I personally cleaned up a lot of excessive wastegate duty cycles when i switched to the Tial BOV. I was running about 19 PSI peak tapering to about 15 by redline.

I've got a chargepipe and BOV on the way, I'm interested to see a before and after log now. For the essence of argument if you just ordered another set of stock DV's that don't leak will they work as well as the Forge ones? Guess I've never just dug deep enough into that side of things.
