Dark red is 30lb. 36lb should be dark blue

Yep, those are 30's, same ones I have on my setup. Those 30's at stock fuel pressure should be good to around 450 hp at the crank, or about 380 at the wheels.

You could always bump up the fuel pressure, but that's usually not the best idea.

so you think i can run at 60 lbs pressure and still be alright around 450hp ? because if not i dont need these injectors and i will sell cheap

What are you doing to the car? Supercharger? If you're going FI, then I'd go up to 36's or 42's. If you're staying N/A, then you could stay with the 30's, and even at stock fuel pressure you should be okay.

Dude with a combo like that, you're gonna need way more than 30's. At least 42's (probably more like 55's or something though to be on the safe side, but I don't know a whole lot about FI setups).

Ditto on everything Cmant1914 said. 30lb injectors will be way too small for a turbocharged 408, regardless of the fuel pressure. I wouldn't buy another set of injectors until you figure out exactly what combo your going to go with and what power level your gonna be at.

don't up the fuel pressure. not a good idea.

42s wont be nearly big enuf for that combo either. i'm going to 42s for my kenne-bell, and i will only be pushing 400 rwhp max. you are talking about probably 600+.

Do a search or better yet find a Turbo forum and see what those peeps are running.
