    A friend of mine is having problems on his b20 engine it keeps blowing up.
    It’s meant for drag race it has everything changed inside and out.
    It only runs up to 2 times then the third run the engine blows he couldn’t reach the final round he only gets up to the qualifying race.
    It’s running 11 sec on the quarter mile.

    Anybody ?
    Or Is this really normal for a race engine?
    What could be the cause?

    Thanks.

    When you say "blow up", what exactly happens? The pistons punching a hole in the block? Valve and pistons hi5 each other? Or what? And since it's a drag engine I'm pretty sure there are secret mods in there you don't know about. Most race prepped engines sacrifice reliability for all out power and I'm sure your friends car is no exception.

    You need to know what exactly "blew up" to determine why it detonated
