Good find!

I wonder if they improved the hydraulics as well? Clutch fluid contamination was a huge issue imo in the c6's.

 

The 6 bolt LT1 Conversion flywheels are done. We've already ran the three variations we're going to be offering through all the tests here at the shop and were very surprised at how well the setups did. That's great news for the guys with C7's wanting to maintain the benefits of the dual mass setup and have a clutch that will hold quite a bit more power and for the guys in the C5/C6's (along with 4th and 5th gen Camaros, GTO's, CTSV's, etc.) that want to have a factory style twin that will actually take abuse and hold power.

We'll be putting one in a C6 tomorrow, we'll keep you guys posted!

 

Unfortunately no, there really is no improvement to the hydraulics inside the bellhousing.

 

I thought this was a "terrible set-up all around?" And didn't somebody else say "dual-mass fly wheel does not hold up to 'spirited launches'?" Quite confused. So, for C5/C6 are you making a sprung clutch disk that will be able to be bolted up to the solid flywheel, or are you making a 6-bolt dual-mass flywheel that will use the C7 clutch and PP? Thanks for all the explanations.

 

Owner's manual says to change clutch fluid every 30,000 miles.

I do the ranger method every six months(~2,500 miles) on my C6Z06 to prevent the infamous sticking clutch problems.

 

Dual mass setups are not ideal, however, because the C7 has AFM there will be guys that are going to want to keep it in there. Corvette's transmit a ton of noise through the torque tube, even if we run dampened discs in the C7 it's still going to transmit a ton of noise because of the AFM. There are going to be guys that are going to remove that feature and want to get serious with the cars, we'll have a replacement flywheel that eliminates the dual mass setup for them, for everyone else we'll keep the quiet dual mass.

We have dampened disc options for the C5/C6 cars. We will not be doing a dual mass for those.

 

Wish I would have seen this yesterday. I ordered an LS7 set-up for my C5Z06. Probably couldn't wait for the C7 disks anyway as my clutch keeps sticking to the floor and is now giving me the shakes if I go to WOT...

 

suck out the reservoir whenever it looks dirty, which is often.

 

Will be installing one in a Gen 5 camaro next week...

The 6 bolt LT1 conversion flywheels are done. We put one in a C6 and, as you would imagine, the clutch feels just like stock and holds great!

We'll offer these in three packages -

LT1-S - $1,099.99 - Street setup using factory GM discs and our Monster Clutch conversion flywheel. This setup will hold 650 rwhp/rwtq and obviously have factory drivability. There is some very slight gear rollover noise due to the lack of dampened hubs on the disc, upon installation in the test C6 the noise was so minimal we didn't feel the need to change these discs as the torque tube on those cars transmit more noise than any other GM vehicle.

LT1-SC - $1,399.99 - Street/Competition setup uses our dampened ceramic button discs and our Monster Clutch conversion flywheel, the pressure plate and setup on the clutch retains factory components to maintain factory drivability with a more aggressive friction. This setup will hold 1000rwhp/rwtq.

LT1-R - $1,599.99 - Race setup designed for all out performance. It utilizes our sintered iron material and our Monster Clutch conversion flywheel which makes this clutch a stout piece that still keeps factory pedal effort and plate load. This setup will hold 1150 rwhp/rwtq.

If you want to pick up your own clutch from a local GM dealership and just buy the flywheel from us it's going to be $599.99. Each package will contain the GM clutch assembly w/ factory or modified discs (depending on which one you choose), pilot bearing, release bearing (we're applicable), and conversion flywheel. Slave cylinders will be additional.

There are some great features on the LT1 clutches that have really caught our attention. Having a built in pedal stop to keep high rpm pressure plate "float" at bay, nodular iron castings, and a great plate load to bearing load ratio makes this a nice factory clutch! Of course we're not fans of the self adjusting pressure plate, but, they've made some changes to the internals on these that vastly improve the design from the past ones. That said, this is the absolute smoothest twin for your 6 bolt setups, you cannot go wrong.

When we removed/eliminated the dual mass setup from the C7 we were able to reduce the overall weight by 15lbs! The setup now comes in at 53.5 lbs with a billet steel flywheel. If we get enough guys asking about a lighter setup we will offer one, however, the MOI on this is lower than a LS7 so even though the overall weight is pretty close the overall "feel" of the unit is that of a lighter clutch.

 

While clutch fluid contamination is obviously present, I think the main contributor to the "clutch pedal on the floor" issue is heat causing the fluid to boil...you can't compress air enough with one stroke of the clutch master cylinder. There are some people who have increased ventilation through the bellhousing and that has alleviated the problem.

Too bad there were no improvements to the hydraulics...did you notice any improvement to ventilation through the bellhousing? Have they gone to DOT 4 or DOT 5.1 fluid?

I have a dual mass flywheel in my ZR-1 and have replaced the clutch twice in less than 50K miles. The last time I noticed the surface really needed a little clean-up but these dual mass flywheels can't be machined...you replace the whole thing. Is there any way to machine the C7 dual mass flywheel?

You've done a great job putting together clutch packages for a large cross section of cars/people, keep up the good work!

 

There are a few things that contribute to the limp pedal situation. What we've seen more than anything else is the clutch actually slipping and causing heat to build up in the diaphragm, once this occurs the pedal is limp - after a few seconds things cool off and all goes back to normal.

Dual mass flywheels cannot be resurfaced... there's just too much movement in the two pieces to provide accurate results.

Thank you for the kind words, we really feel this setup will be very beneficial to customers in the current market.

 

What are my options with this? My C6 makes 660 HP to the wheels NA power...💥🏁🏁🏁
