Fuel rail questions

[Moneywellspent]

So I did some data logs awhile back and come to find out my cp3 was only holding about 18.5kpsi. I have stock injectors still but got a screaming deal on a exergy 10mm. I know it's a little bit of over kill for stock sticks but I plan on upgrading those after deployment.

But before I just jump right in what would everybody who's done this recommend I do while I have this thing apart? Should I do ported fuel rail fittings or anything of that nature? I definitely plan on upgrading lines from the lift pump as well.

I already have my fprv plugged and a lift pump to keep things clear.

I wouldn't port fittings. Those oriface is for smooth consistent flow. It's not small enough to effect flow where one rail is falling behind

I would port the DS at least to 1/16". I gained 1000psi from drilling it out to 3/32"s and 300psi from modding table B1015. That was a stock CP3 and injectors though so you might not need to do it if you are doing a 10mm with stock injectors.

I have stock fittings, a 12mm CP3, and I had no problem holding 26k PSI at 2600uS with 100% over injectors. I've seen evidence both for and against porting the rail fittings, so I left mine alone to see how it did. I figured I can always port them later, but I can't un-port them lol.

Thanks for the input guys. I'll just stick with stock rails for now
