its all in the setup guys and gals. if you run a clutch with big systems your gonna want to bang it. dump the clutch with a cough and your gonna need a scoop. MOST of the cars that launch the scoop have another issue that happens to pop up at that time. we have always banged and to this date have never had an issue, we bring the car to 2500 and bump each kit. don't know if i would try it from idle.

No way a couple 1" sized holes, are going to save the top of your manifold, if it coughs. Waste of time to even install them. You want to attempt to save your manifold in the event of a backfire, put the top on with plastic bolts.

That way the carbs can now become flying shrapnel as well? The burst panels are meant to help the release of pressure. Kind of like the holes a fireman chops in a burning roof with an ax. Its not meant to save the roof, its meant to control the continuing blasts. I've seen two dominators still bolted to the top of an intake that was split in half with both halves vertical east/west. The main point being the carbs were still bolted to the intake. With plastic screws you risk large pieces of flying debris at crew members and track personnel. Did we not see a picture of a well-known pro mod car and the carb was sitting on the ground next to the car at the starting line just this last year? Racers, please use the burst panels!

Fultons spring loaded reliefs worked just fine for me in this situation. The previous old school pop-off discs (burst panels) ended up lifting the manifold top. The new spring loaded reliefs relieve that pressure without damage. I've actually saw a quick flame flash from inside the car when it happened on my car. Motor stumbled for a quick second, fired that system again (Cleanly this time) and I made the run.

Had this happen with another sheet metal manifold motor with an IS Solutions pop off as well. Motor stumbled and shut off. Re-fired...purged again, and made the run. No damage.

As Bushmec said above, that same stumble on the launch will create some interesting after effects.

The burst panel plate or spring loaded will not save you from a real boomer.
There fine on a sneeze.

The plastic bolts are the only thing that seems to save it.

Then thether the top plate to the intake this keeps it somewhat in place so the fuel lines don't get ripped off that's were your seeing the fires.

Sounds like you nitrous folks now need straps and a ballistic bag just like us blower guys. Shhh, don't let NHRA or SFI hear about it.

A whole page full of reasons why the purge works fine in my book, including when the clutch & Lenco were still in the car!!

You could always use some of them NASCAR aproved carburetor tethers.
