lean or not ? hi , i'll tune my car in a few weeks , my mods MS4 , walbro 255 fuel pump , fast 90 with 90 T/B , full exhaust with SLP LM cat-back , diamond flat top -2cc , stock rods with ARP high performance bolts , all ARP bolts/studs , stock 241 heads , my question is : how much the maximum shoot can i spray ? my nitrous kit is wet , so i'm planning for 200HP , i want the maximum shoot without leaning
the guy is from the middle east, im sure your not to good at speaking arabic, what he meant is how big of a shot can he do without running to lean.
my advice is to get a wideband and try it out, better be safe than sorry, especially with a built motor.

You will tune the fuel by jetting (adjusting jet size). If your puling fuel from the tank then a smaller jet (higher fuel pres) or standalone (low Pres.) I would suggest not only getting a wideband but a standalone fuel cell. You are gonna want to run race or high octane fuel w/spray and a larger jet is less likely to clog. Money well spent. Your N20 afr should be 11.3-11.5. imo
I am assuming that you are meaning how much can you spray before running lean due to not having enough fuel supply to support the horsepower..
If you only have a walboro fuel pump you are good to about 450-500 hp.
If you have a hotwire with it you should be good up to around 650hp.
