Question Info About BOP Clutches Please

Heard about a BOP clutch and wanted to learn more about it. . . . . . . .

Is anyone using them on here?

What kinda power do they hold?

How are they compared to the Textralias, Specs, McLouds, etc.?

Any details anyone can provide will be appreciated.

I've seen some GTO's and Vette's running them... and they seem to do well. I've seen people on the forums suggest them over the Textralias and other mostly used clutches so apparently they have to be decent.

I looked into them. In my opinion its just not worth it. They go $1100-$1200 and it's a single disk? Just go get a Textralia oz700 . Tons of positive feedback and only $900

Go down to your local cluch shop and have them make you a disk with velvettouch buttons on it. Buy an aftermarket steel flywheel and a Luk non adjustable PP. Any machine shop can balance the assembly for you. You need to measure the distance between the tip of the PP release arms and the face of the bellhousing where the trans mates to it. I had to shim my slave .150 thou. out and that left me with the slave compressed .120 from bottom. I paid $500 for all my stuff and beat the hell out of my car constantly with 400+ RWHP. If you want an even more agressive bite, you can use the iron pucks instead of the velvettouch but they chatter more. For me, there was no sense in spending $900+ for a cluch when I could do as well for $400 less. It just takes some time to measure and footwork to the machineshop. Im running a 346 with AFR 225's, Fast 90, 228/230 XER comp. cam.

BOP. Not worth what they are asking for and IMO very poor material design.

Great info-
Could you explain the "measure the distance between the tip of the PP release arms and the face of the bellhousing where the trans mates to it" great info.
I am very interested in BOP for puck design and possible ease out of the hole. Anyone have any drag radial experience out of the hole on a prep track? can you ease it out or is it on and off like the powergrip HD ? still working on 11 stock full weight.
I just pulled ram setup and PP is to worn to reface. About to buy tomorrow- either same ram setup or try the BOP

I am very interested in BOP for organic puck design and possible ease on launch. Anyone have any BOP track time time with dr's on a prep track? can you ease it out or is it on and off like the powergrip HD ? still working on 11 si full weight.

The idea is to find out how much the slave is compressed when you install the trans. If the slave isnt compressed enough, you wont have enough pedal travel for disengagement and if you bottom the slave out, it will cause the clutch to never fully engage. Either case can lead to clutch failure.

As posted on another forum, they use a stock pressure plate that is modified for more pressure, and they also use a stock flywheel that is from the same place gm buys theres.

The only way i can see it holding any more power then a factory one is they use a 6puck disc, it looks to be a kevlar ceramic disc, similar to the spec 3 6puck.

For the price tag you can get into a spec 3 + which has been proven and doesnt use stock parts, and its flywheel is also SFI for you racers.

The benefit is it is SFI approved, having 2 feet at the end of the day is a good thing. Not saying the clutch will blow apart on you, but the sfi sticker says they paid the money to have it checked out.

The sintered iron pucks are a common for max torque rating, in retrospect they also tear up the flywheel and pressure plate quite a bit faster then a normal clutch.
