Just a quick note that I experienced with my car last week.
My 2018 GT, Whipple 3.0, A10, longtubes, no cats car ran great with 93 octane with the ID1050X injectors and DW400 fuel pump.
I changed to E85 and added the JMS Fuel Pump Booster at the same time to (hopefully) ensure I had enough fuel volume with the larger 3.875 pulley.
I set the JMS up and hit the toggle switch for the 22 volt option, thinking if 18V at WOT is good, 22V is better right? WRONG! (for my car at least)
We made a few logs and saw that my fuel pressure was dropping above 6000 rpms... I went to the search tab here and began looking for content on others settings and then spoke with robw_39 on here and I have been talking lately comparing combinations and he was running the 18V option.
I switched to the 18V and made a log and sure enough, I had solid pressure again with no drop on E85 and the 3.875 pulley!
I ran the 18V at the track last week and it was solid so now I am going to try the 3.625 pulley soon and log to see if the pressure will sustain with a little more power. I know we are on the ragged edge with these cars fuel volume wise at this power level and the 100% safer and best option is to move to the complete fuel system and that will be in the future for me.
Maybe this was common knowledge for others already but I wanted to share my experience before someone may assume like I did and has a costly mistake.
Curtis/Mustang Mods told me, when weighing in your cost for a larger build, look at the cost of a fuel system vs. a Boost-a-pump expense so you don't have to buy twice..... like I am going to.
I'll update as I test later this week.
