I wouldn't risk running just the stock pump and bap with that power. I was running 780rwhp on a Z06 pump and BAP. It was working but I knew I was pushing it so I added the ECS stage 1 fuel system at that time for safety. Easiest route to go.

I was making 690@ 8lbs boost on a mustang dyno with Stock pump, BAP and METH and was having issues with fuel pressure dropping after about 6400 rpm. That was with a 4" blower pulley and 8.5" damper overdrive pulley. We ended up going to a 4.5" blower pulley and are now about 7psi boost and able to go all the way up to 7000 rpm but I feel the fuel is at its limits on my car. I went with a FORE Innovations stage 4 double pump set up with return.

Im doing my Clutch so im just taking advantage of doing all these mods at the same time given that the drive train will be out
if your making over 700 with the stock clutch, its going to go eventually. Sucks to be running that GTR and you get a good jump on him and at the top of 3rd gear your clutch spins and he walks on you.

Yea putting a monster stage 2 clutch in it. I had no problems with fuel pressure at 707rwhp with bap and stock pump on meth. We will see what it does on the dyno this week. My tuner is very good so we will see

Why not one of their LT1 based ones? I don't think the stage 2 ones are rated high enough unless I'm missing something.. they are a single disk I thought
