Whats the next step up from the Walbro 255 LPM ?
Why do you think more than that...Your combo and a 255 is fine for 600 crank HPWhats the next step up from the Walbro 255 LPM ?
you ever clean it3.5" and translator upgrade , I have had that for a couple of years
def dont want to be lean at 30psi,need to see if you have fuel pressure on the rail at wot,also need to see pressure on your meth system as well.thats where you should start.i dont know how the car is tuned but you could also richen the car up 5/6%.but without the right pressure tuning adjustments wont happenBeen getting some lean numbers at 30lbs of boost , I have turned the pressure up
Thank you , I will check that outdef dont want to be lean at 30psi,need to see if you have fuel pressure on the rail at wot,also need to see pressure on your meth system as well.thats where you should start.i dont know how the car is tuned but you could also richen the car up 5/6%.but without the right pressure tuning adjustments wont happen
Will do soPost your PL file from the run. You are datalogging...correct?
30psi on a single nozzle.740s/760's is not what i would like to see,if your pulling plugs and that is where it wants to be i understand but thats pretty lean inmo.Went out this evening and the Alky was set at 5.5 and got 740 mv with some knock
i dont think this is the answer,the pump pressure needs to be looked at,also the fuel pressure and i believe you should be added more fuel via the chip and target no lower than 780's.the narrowband and wideband reads all cylinders and when your low on the mv you could be leaner on your leaner cylinder,volume and octane fix this.Turned the Alky up to 8 and got 760 mv with no knock so I believe I will get me a new pump from Alky control and go from there .
5.5 to an 8 on a single is not going to add that much alky/and with alky you will need alot more on the volume side bring the afr up,what you did was cool the charge more and add some octane.Alky was set at 5.5 and got 740 mv with some knock . Turned the Alky up to 8 and got 760 mv with no knock
