Affordable Fuel Pump Upgrade -- if it is possible

[norm8332]

You should be able to hit 550 or more with that cam. I was at 500 with my previous cam without spinning the hell out of the SC - 3.2 pulley and no overdrive pulley.

I have a zl1 fuel pump set up with 60lbs injectors atm going to id850. The pump has held up just fine and the car is 750-800 rwhp. Just adding a bap and bigger injectors for my sense of sanity.

You're hitting 750-800rwhp on the stock 376 and Maggie? Or with the 417 motor?

800 rwhp through a auto with a zl1 pump and 60lb injectors... Not

I'm def in the same boat as you, I need to upgrade my pump and injectors. I've been leaning towards the ZL1 pump but i'm not sure If it will be good past 600, I'm currently at 579rwhp with some still left on the table

So who is the "almighty THOR" related to this ZL1 pump setup & install?

[Semperfire]

ZL1 and a BAP should be good for most power levels. Not the best set up but cheaper than some of the alternatives.

ZL1 pump is fine for your power level. I know a couple of the higher powered G8s have them and no issues.

I recall reading about the gas gauge reading "being off" with this ZL1 pump -- requiring "some adjustments." Was a fix found for that?

....or was that the CTS-V pump? .....or is my brain throwing a DTC code?
