    Fueling solutions and goals

    I've seen dynos up to 550whp with stock fueling and meth (ASR). What whp are people with upgraded fueling aiming at?

    The only solution I've found so far for 540rw is 4.7v of fuel pressure (3500psi?) and 2000ml/min of meth flow. Would love a better solution. Click here to enlarge

    That is a realistic goal and sounds about right.

    but how much boost can we add to reach those numbers with the stock compression ratio? I mean is octane, fuel coupled with the right timing advance able to push 600 whp ? (not considering internals like rods etc)

    Depends on your compressor, ambient conditions, oil and water temp, how strong the head studs are, etc.

    600WHP is definitely possible. It might even have been hit. Click here to enlarge

    If you swap turbos or switch to a large single, you can make more power at the same psi.

    I was using two of the old school M10 nozzles. In theory we may be able to squeeze a little more fuel enrichment through the meth system but at that volume I'm very worried about distribution and also explosions. Click here to enlarge

    Explosions? How could that happen? What do you mean be being worried about distribution?

    Each cylinder may not suck in the same amount of meth ect.. Explosions can be caused my meth pooling or a backfire caused by hitting the rev limiter... Dual cm 10 nozzles is a lot of meth

    Worried the outside cylinders may receive less fuel if the manifold is really saturation with it. It's designed only to route air normally.

    On the explosion a bit of a joke. Another forum member blew up his intake a couple weeks ago, presumably from a meth backfire during a no lift shift.
