sleezy rule of thumb: (2/3)*injectorcc = max hp @ a 'safe' duty cycle (~80%)

In the DSM community it's recommended to get something larger for anything over 300ish HP. But I'm sure you can find someone that made more power on 450s. Check the DSM boards/forums.

Here are the guidelines we use for sizing injectors.

Flow Rate vs. HP Level
(Flow Rate for each injector,
in a four cylinder setup.)

310cc 200~220whp
370cc 220~280whp
440cc 280~330whp
550cc 330whp~380whp
660cc 380whp~425whp
720cc 425whp~475whp
880cc 475whp~525whp
980cc 525whp~600whp

Hope that helps,

Craig

Anyone know if Y8 injectors can be used with a P28 (Z6) ECU? Do they even plug in to the P28 injector wiring harness? I know Z6 injectors are 235cc and the Y8 ones are 240cc. A friend of mine have a D16Z6 and asked me if this can be done... just wanted to know for sure...
