will it work? Yes. Should you do it? No. Why? The C7 has a known issue that when the intank pump is worked too hard it will overheat and die under racing conditions on C7’s that haven’t even been modified. Several people have had their C7’s bought back through lemon law as a result of this. Because everytime they would replace the pump the owner could replicate the issue again under the same conditions.

The ZR1 and the 2019 Z06, (and only the 2019 Z06, not prior years) were believed to have a higher flowing pump, however, if I remember correctly it was discovered that the pump is voltage regulated to run at a lower PSI than all the prior year C7 in tank pumps (which were all the exact same regardless of Z06 or non-Z06 prior to 2019) until it was commanded to pump higher, at which point it would be cooler for a longer period of time to fight the overheating issue. The max PSI on the low side remained the same though. If I remember correctly, all C7 up through 2018 flowed 72 PSI on the low side. In 2019 they flowed around 59 PSI and then when commanded higher based on acceleration demand they would raise to 72 PSI.

Knowing this information, do you feel comfortable trying to boost this pump? I sure don’t..
