Has anyone ever seen or heard of theses so called "preformance overflow valves"

I am testing some ofvs they work very good.

As said, they are race only, not good for street use.
Return flow on these valves is low which results in less cooling and lubrication for your pump = shorter life.
Tork-Tek has a couple of other adjustable OFVs that are excellent for street use.

Not sure the point of that. Jim Fulmer did dyno tests on different fuel pressure up to 100 psi, never gained anything over 40.

Imo there are better ways to make more power than limiting the low pressure tank return flow. This looks like just a cheap and dirty way to get more fuel than the lift pump can deliver. IE pointless for a daily driver. Probably a bit harder on the lift pump, too.

For some folks it's hard to break loose from the more is better mentality.
I run into it all the time with farmers who think adding more pesticide to their spray tank is better. Most times all it does is cost them more money and damages their crop.

See the same thing all the time on these boards with people who think having a ton of extra boost is going to gain them anything.
Same goes for fuel pressure it appears.

Sounds like the bigger must be better syndrome, I hear everyday.
