What is your fuel system capable of, what PCM are you running, and do you plan on using meth to supplement fuel up top?

Dual welbro 255 stock rails aramotive FPR. Stock pcm, did not plan on meth injection to supplement. But I could be wrong this my first supercharged build.

In that case, I would run some ID1000s if you want to be super safe, and or push it later on. But, since this is the real world and spending $800 on sticks is crazy for most... grab some 80# deka sticks. Just be aware you will be limited by fuel and not air IMO.

Keep an eye on the Aeromotive AFPR if it's the LT-1 specific unit. I've seen a few of those fail over the years. Bumping the Deka's to 4 bar (58psi) will gain you 15% more headroom.

The walbro's will not like the 1:1 rate with a base 58psi

True. The high pressure version of the Walbro makes sense for FI.

Is it an issue with the pumps themselves or the pumps paired with our stock fuel lines?

Both, you can prob squeak more head room by bumping to 8an but you will still be limited by a pump that does not flow well at high pressure. Originally Posted by Catmaigne
