If you think it's an actual possibility, I'll send you a bunch of carpokes stickers. Heck, I'll send you stickers even if it's not a realistic possibility.Darwin wrote: Thu Apr 10, 2025 9:11 am @Tom Do not tempt me @chris white ! We literally launch weekly! I may be able to sneak one on board a second stage since it burns up lol
Remind me your shipping address if you want to try. No pressure at all, and please don't risk starting an interplanetary incident if this would violate Starship Federation rules or anything.

Figured I'd post my recent "upgrade" to Radium products.
Not sure I like the mounting, would really rather go back to stock.
Just can't justify $900 + for a NOS fuel rail.
OP are you running a FPD? Or only the regulator.

I'm only running a regulator. If I start to see issue while tuning/running I'll consider throwing one back in but for right now it simplifies the system.

Damper is only needed in a batch fire set up (like stock) if you are running sequential you don’t need one.
In batch fire it opens all the injectors at the same time and that sudden change can effect the fuel pressure. If you are opening them one at a time there is not measurable pressure change.
I just installed a rail mount radium regulatior – really nicely made and I like the gradation on the unit as well as the clear click step on the knob. They are now my standard part on builds!

Can't recommend the Radium FPR enough. The fitting that ships with it is -8ORB. Just make sure your rail is cut for that and it'll fit right on. Fuel return line is adjustable, FPR clocking is adjustable, vacuum signal is adjustable, and each click on the dial is roughly 1PSI of pressure.
Shout out to @chris white . Without him I'd still be in the 1980s as far as engine and engine management technology (along with many other things!).

To echo Darwin...you have certainly been an asset to the forums for many years.
The Vitesse V-MAF+ software I run is (semi) batch, so I guess I'll stick with the FPD.
