ok now i know.
Is the car running right now or are you still installing parts ? 12:1 FMU @ 5psi of boost = +60psi fuel pressure base pressure = 45psi => total of 105psi how much does a walbro 255 flow at 105psi rail pressure ? (not much) http://www.celicatech.com/gallery/files/2/4/walbro_chart.gif so assuming the pump had the flow ... you'd only have 167-182hp worth of fuel... tops. if you run 7psi on a t3/t4 on an ST you could see 200hp worth of air...which is too much for the fuel you have in your setup now. my advice is 300cc injectors (good for 200hp) and a 7psi tune ...much safer than the setup you have now and much more reliable even though the boost and power are higher This post has been edited by NuclearHappineS: Nov 10, 2006 - 2:07 PM -------------------- 2005 MB C200 Kompressor- K&N, Apexi WS2 Catback, DIY Voltage stabilizer, Intrax Springs, H&R RR swaybar, VDO Boost Gauge @ 6psi, Greddy L7 plugs, +0 Rear tires
