3-4 clutch pack
3-4 clutch pack Has anybody had any issues with the Raybestos Z-pack. Its a single sided clutch system. The selling point is better heat tolerance. I've been using Alto Red 9 clutch packs in my builds with no issues so far but those steels are very thin and I'm afraid what some higher than normal heat would do to them. I know there are some experienced builders in here so please chime in with an opinion. Help out a novice builder.

I'm running the Z-Pack in my car. Just installed, I've made 6 - 10 second passes at the track and about 200 street miles so far.
Not as harsh as the Red Alto pack (Ran that in my last rebuild) for street driving.
So far, so good!

Thanks for the shout. I didnt know much about them but if they are holding up to 10s maybe they are as good as advertised!

The 9 clutch Borg Warner Hi-Energy 3-4 pack is what I have been using in a low 10 second 1996 Firebird. I can't speak to how the Z-pack will hold up, but I will continue to use the BW 9 clutch setup, as this has proven itself for the last few years.

The vast majority of what I build uses the 8 clutch Borg Warner Hi-Energy setup with 2 .128 steel pressure plates, .055 5 tang apply retainer, 4 or 5 .080 Kolene steels, 2 or 3 .060 Kolene steels, & a .062 snap ring is used to achieve .030 - .040 clutch clearance. The 9 pack is for maximum longevity at the drag strip, or for someone who has 600+ HP.
