My GOD you two are friggin IDIOTS. How many posts have you seen on this very site describing hydrolock? Small, 100 hp 4 banger engines can suck water through a 3 inch pipe 30 feet straight up.
A bypass valve is a good safety measure, but most of the time.. it won't do much.
As for other safety precautions; shift early and keep the RPMs VERY low. The less RPMs, the less chance of hydrolock. A bypass valve will help if your Intake
gets submerged- and only then at low RPMs.
Get one (better than AEM
) when you have the chance.
Don't follow close behind other cars, avoid pooled water where you can. Be especially careful first rain after a dry spell
