REs couldn't take abuse (two sets) without damage, BWs held great... same aggressive driving in my old C10 (5.3L/4L65E). Same install method. Luck of the draw or what? LOL

Dana from Probuilt has an interesting story about these two.
Said Gil Younger, founder of TransGo, told him to take a borg warner green and an alto red, dip them in trans fluid for a second and see what happens.

The borg warner green absorbs a lot of fluid while more drips off the alto red.
The more fluid a clutch disc can hold the cooler it will run and will be more resistant to burning under hard use, especially when thinner plates are used to fit more discs in the set.

I use the BW high energy I have had good luck with the 8 stack in the 3-4 setup using the thin steels with .018 installed clearance with the stock PP and snap ring. Have this setup running in numerous 10 sec and even 2 9sec vettes. I also use the carbon band over the RE band. The stock HE clutches are damn good clutch you just need more of them and the clearances set right. I use this etup for my HP builds and I will use the Z-pack for my HD builds.

What's the difference between a hp build and a hd build?

I had 3 reps from Raybestos in the other day that just stopped into say hi. Wanted to see our facility and also to talk product. Keep in mind I have been doing this for 20yrs this month.

He asked what we were using for clutches and I told BW's is what I normally use. He mentioned the Z pack and my opinion on it is I do not like the thickness that the friction material is mounted to the plates. He said it really is not a problem because of its design. I said really........ went over to a shelf and grabbed a few sets that we took out of units. I said here look at how the clutch material is wearing funny and also the steel material look like a damn slinky! Quickly after that he mention using a different line of their product for frictions.

My point to them was that at the end of the day a friction is what it is. It either works and lasts or it don't. Simply put! My opinion is what it is. I feel that you need steels to support the clutches. The alto pack's in most cases have you using thin steels to add friction plates and that goes right back to my opinion on the zpack. You need something to help with the heat.

I have been using Borgs while I have worked at FLT and the last shop they were big Raybestos fans. However I found that to make either of the clutches last a good amount of time the steel plates and pressure plates were the key to either making a good 7 or 8 clutch setup. Also the over all clutch clearance is very important here.

I use .062 4l65E HE frictions with .080 Kolene steels and have had great success with this pack. I make my adjustments for clutch clearance either by installing a thicker friction(.080 or .067) or by changing the apply plate(two thickness plates) or one of the 4 pressure plates we keep in stock. With using this and setting the clutch clearance between .015-.025 dry it seems to work pretty well for us.

I will suggest using the 7-cs kit that comes in the HD-2 kit and also making sure that you have a solid hydraulic built unit for the success of your build. After all clutches are just part of the build. Best of luck. Vince

Does the 4l60e just physically have no room for a larger clutch pack or hub? It seems like if there was a fix for the 3/4 clutch pack it would be a great trans.

As vince said if the 3-4 is setup right it is fine for what the 60e is logically meant to handle.

yeahvince i like using the thick frictions and thin steels I havnt had a problem with it I dont like the z-pack for HP use either I do like it for HD towing units. I would actually have to thank the guys at RPM for getting me away from the Z-pack for HP units when I was on the phone with them talkng about a unit that had chattered a input sprag that iwas fixing. It was a rpm unit behind 850 rwhp and it actually chatered the sprag and broke the rings. They were very helpful in thier specs I wa really surprised they would give that info out iwanted to set the 3-4 back the way they ahd set it up during the discussion we talked about the z-pack and they made me realize it has its place. but not for HP builds. BTW let me add it wa sa nice lookin unit also inside I was impressed with the work in the trans.

Vince, Predator,....can you give me some advice. I've had my 4l65e rebuilt twice this year because of 3-4 clutches. I'm putting 600 wtq through them and in 4th it just wont hold. I could stop driving it like that, DD, but I thought with this latest build I would be able to enjoy my rides to work. Trans dude thought I was torching them because the input drum was flexing and leaking so he put in aftermarket: Input shaft, Wide band and drum, beast sun shell, wide extra/roller sprag.....but I slipped 3-4 the first day I drove it.

He only used 6 frictions, which pisses me off. He said heat transfer when the 3-4 are not in use may be a problem.....I can't remember the brand clutch he used. I'll find out Mon.

Last spring I had Raybestos stage 1 z-pack installed and they lasted 6 months. On the stock line pressure.

This latest guy said he turned the pressure up a bit. I have 205 in forward and 250 in reverse. He is looking for a way to get 250 in forward without raising reverse to make the 3-4 hold.

Which clutches for 600 wtq daily driver: Raybestos blue, stage 1 z-pack, Alto read eagle, Borg Warner high energy.

Any input? Which clutch, how many, line pressure.

8 BW green and the rest built right.

You shouldn't need more than 230 psi at wot.
Sounds like your trans guy is taking shots in the dark and learning off your build.

Thanks. I don't think I've tried that clutch yet.

I went to this guy this time because he builds race trans and is a sponsor at our track. I was willing to pay him double what I paid the last guy because he is supposed to have experiance with this level of power. Hasn't work out to well for me. But for what I paid I'll make him do it over again.
