    Are you running an aftermarket intake grate such as the Riva?

    I'm thinking the same thing, but I thought I better ask first so I don't look like the idiot that I am sometimes.

    That noise is the signal coming from the government, telling your machine to use more gasoline because $108 barrel is very nice for Bush.

    You got me I have never notice this noise.

    It's just the grate. I don't know exactly what's going on, but if I had to guess it's probably just the scoop picking up water in the turns and keeping the pump stuffed. I'm not sure though, someone else can probably tell you for sure. It's nothing to worry about though.

    Grate

    I cannot confirm this but I have been hearing that the riva grate can tear your pump tunnel up due to the increases water pickup and faulty mounting. I hear the R&D w/ the gurdle is a better bet.
    As I said, I cannot confirm this and I just bought the Riva. If I notice anything out of the ordinary I am going to switch.

    Sean, where have you heard this from? I have never read that and would like to see pics and read about the instances. I know Vern reinforced his pump tunnel just for extra insurance. As far as grates getting pulled out I have heard of this, but more with the RXT's. You can run the girdle with the Riva grate, but you need to modify the girdle a little bit to get it to work with the Riva grate which is not a big deal. The R&D grate will provide better hookup in chop than the Riva, but has shown to be 1mph or more slower on top end in ideal drag conditions. Above the 90mph mark guys like JD1 have found that the WORX grate is the best with some tuning.

    Another thing that confuses me about the problem is that the Riva grate doesn't stuff the pump as much as some grates like the R&D. That's why it has been a better top speed grate. So tearing up the pump tunnel from the increased water pickup just seems odd. This is interesting though and I would like to read into it more.
