Yeah I normally dont link threads but I need some speedier answers...
Basically, I am running a Racetronix kit w/42lb SVOs on a my TA with Stage II 6.0L heads/TR224/227/D1SC making 8lbs or so.

About 6k at WOT the fuel pressure drops to 48-50psi Suggestions please. Ad an inline pump maybe?

Thanks

I had the Racetronix dual pump kit + SpeedInc. Fuel rails. My fuel pressure dropped just like yours. I put in a #8 teflon feed line a boost reference regulator and a #6 return line. That fixed it. I did also modify the fuel pump setup. It comes with a 5/16 T, I had a shop make a 3/8 to 1/2 Y off of the fuel pumps (since I had to put in a #8 bulkhead anyway). I don't know if that was neccessary. I wish I had taken a picture because it was a very slick setup.
