Direct port meth injection

jmtx86 · Aug 14, 2008, 07:06 PM

Im looking to put a jet in 6" from the TB and a jet in each intake runner. Im looking for a good kit to support this setup. I would like to have something similar to aquamist's kit which taps the injector harness to make sure you done "flood" the motor with meth.

What size jets should I use in the intake manifold and what size should I use in the intake runners?

Im looking to safely support 500 whp on the stock block at around 27-30 psi.

PS if anyone is interested in a trade I have a nitrous express kit with bottle warmer kit (pressure senors on/off, gauge) purge, fuel and nitrous solenoids. It would include all lines needed to install but no wiring.

Just food for thought.

I am not a big fan of direct port injection. Usually the same cooling gains can be had by going the simple route and only running 1 nozzle. Or 2 if running dual intake tracks.
ON a s4 i would recommend going with a total of 7-8gph of nozzle size.

If wanting to do a multi port i would run 1gph on each cylinder and 2gph on the intake.
