My ZL1 pump drops fuel pressure and maxes out quick on DC with E85. That's before the DSX pump kicks on at 9psi boost, too. Wonder how I could get it to kick on sooner like yours at 4psi?

Mine actually kicks on pretty instantly (2psi). Usually when I floor it, I'm instantly at 6 pounds of boost to start, so its on immediately. That will fix your fuel pressure issue.

Looking at that DW400. It does look like the best returnless system. Could be used with the DSX pump also.

AGP has a twin pump setup ,E85 compatible, that is priced really reasonable. It's good for up to 1200whp.
On a separate note, for informational purposes, with just the ZL1 pump, ADM FPCM, the LS9 cam, stock diameter balancer, my car made 600rwhp with the 4" pulley on the Whipple, and 630 with a 3.75". -Scott |
