Any CFM+ manifolds exploding???

I've been hearing a few people having these explode due to the plastic material. Anybody else have any issues with this product?

They have actually blown at 45psi, so they guy that made it to 60psi must have had a good one.

Between the intake horn and the intercooler there is a plastic pipe that comes on our trucks stock, I wonder what it's capacity is?

that pipe is also prone to cracking w/ increased boost pressures over stock.

If you call CFM, will they warranty the piece? I loved the dyno results the CFM made, but if my intake horn exploded while I was driving my butt might explode right after.

I think I would just run a cast horn...even more so if you are pushing big boost numbers....did the AFE get tested in the intake horn test???

yes, the big 3 in intake horns, ATS, AFE and CFM+ all got tested ... they all did very well, with the CFM filling out just a little bit better on the bottom end than ATS and AFE, but ... with some extrude honing on the Aluminum intakes, it may make as much HP as the CFM down low ...

Still questionable what caused it to pop like that. NOs/Meth could have played a contributing factor if they used it.

There's something about the incident that doesn't seem quite right, almost fishy. There are definitely details missing from the story. It's looking like it's a good opportunity for a manufacturer's rep. to get on the boards and start blasting another product, in a round about way to promote their own. It's like kicking the crap out of someone while they're down.

Watch out before you start pointing fingers. I agree the one situation in one of these threads is fishy, but this is not an isolated case, others have blown, but there is no info on those either.

How was he promoting his product, I haven't read anything about the BD manifold in these threads.

according to the bd vendor, they weren't using nitrous. He said they were only using water/meth. 60psi MIGHT cause something to split, but I don't see how it could cause the explosion they are describing.
