i run a spray bar setup in the lower manifold done by nitrous outlet... changing jets is a pia but you avoid the spray through the blower bit... they used to do the mod to your provided lower for about $500 with jets included...

This is the way to do it. Can you provide more details on the setup and power results?

For real??

A returnless system speeds up and down the pumps to maintain pressure. Doesn't really matter if the fuel solenoid opens up on the line in front of the rail or on the rail itself. Either way there was a sudden lost of pressure while the pumps spin up to bring that pressure back in check.

On a return style system the pumps are running full power 100% of the time with the regulator controlling pressure so when the fuel solenoid opens the regulator can compensate dang near instantly because it already has full fuel pressure behind it to work with. There's no waiting for a pump to spin up faster to create the needed extra fuel/pressure.

On a returnless system spraying a 200 shot you might be better off with a stand alone fuel cell in trunk with its own pump and not touching the existing fuel system. Or just see how big of a lean spike you get and see if it's something acceptable.

Stand alone it is.
The way they come they have the regulator on the fuel cell, if you’re going to mount it in the trunk I would move the regulator up to the motor bay so it’s closer to the solenoid. Maybe it’s not necessary but I’ve never seen any other regulator mounted in the back of the car.
