How much boost?
Does anyone know what boost level I could run for a safe but powerful daily driver. And what would be the max boost I should run for the track.
Setup: D16y8 w/ stock internals 55,000miles T25 turbo internal wastegate no play or wobble Front mount intercooler 30long x 6high x 2wide 2 1/2 inch piping Walbro 255lph fuel pump Denso Iridium Spark Plugs OBX 10.3MM Spark Plug Wires MSD SCI ignition Vortech 12:1 FMU Turbo XS Boost Controller Missing Link Stock Exhaust Automatic Trans Autmeter Boost and Air/Fuel Gauges Stock Injectors, Fuel Rail, Fuel pressure regualtor open to any suggestions thanks |
Re:How much boost?
7-8psi should be about right, I would watch your air-fuel gauge to see if you are running lean or not under a heavy load.

Jeff so just cause we say 7-8 doesn't mean your limited to tthat, keep that in mind. i have seen your motor take a 125 shot of nitrous with some si 240's and timing retarded. anything is possible. |
Re:How much boost?
What besides injectors could I do to be able to up the boost. I wanted to max out at around 10-12psi.

You simply cannot run that much boost on stock injectors, you will have to upgrade them if you want to make some real power.

Re:How much boost?
you can run up to 10psi with stock internals. The Vortech FMU is the perfect ratio for stock injectors at 6psi. If you want to go the full 10 then you will need to retard timing 8-10 degrees, get a blow-off valve, get some DSM 450cc injectors and call vortech and order the proper recalibration kit for your FMU. They run like $40 shipped from Vortech. ;)

Re:How much boost?
What will the proper recalibration kit do to my FMU? I have a blow off valve, I forgot to mention that. My main goal in the end is be at around 200hp. If I got DSM injectors, would I still have to slow the pulse down if I retarded the time? Does anyone have a 450cc injectors they would like to sell?

How much HP do you think your buddy had on his Turbo Corolla? Jeff |
Re:How much boost?
Which recalibration kit should I get. I was going to get the all in one with 4:1 6:1 7:1 10:1 12:1, but which one should I use?
