  • The only way you maxed your injectors out with 286whp is if you are running an AFR of about 7, which sounds about right with your 14lbs of boost lol.

  • @footballplaya3k So i could of went with 42lb injectors and been fine. But i am now building top end of the motor in april. So im removing the 1.9 rockers and doing the XPZ cam with cnc heads, full stack intercooler. So I will need the 60lb injectors now. Stay tune and i will have more videos coming of the build and the dyno.  ;-)

  • Why 65 lb injectors on 3.4 pulley!? Stock injectors are good for that much boost , running the blower 42.5 lb were plenty on my genv setup with 2.76 pully , unless your running e85

  • @l67swap1 yes it would be but. I did max my stock injectors out while getting a dyno tune. so instead of going with the 42.5 and have to get the evo conecters for the L32. do to there not plug and play. I went with the 65 lb about the same price and gave me room for more fuel in the future. I now have a full stack intercooler and it runs great. I have also not rulled out e85 yet. what are your mods?

see all
