PCV or breathers on a drag car

The benefits of a vacuum pump don't only apply to track use...
Now I wouldn't drive around pulling 15-16 inches all day. I would dial it back to something like 6 inches but that is still beneficial.
Are you speaking to the fact that some vacuum pumps won't last nearly as long if they are continuously in use seeing lots of hours. But the GZ Motorsport pump is designed to wear slower but at the cost a little bit of performance. To my understanding at least.
OP if it is a true track car as in it NEVER sees street use AND WILL NEVER, might not have a water pump, full deck fill, no alternator blah blah blah. If this is true it is likely to assume it is pushed to staging lanes fired up, makes a pass, and either shut down at the end of the strip and towed or gets back to the pit and shuts off immediately.
If this is true, go with just a catch can oil separator with lines from the valve covers. If it still sees some street use and longish operating periods just add a separator in line after the PCV before the vacuum reference on the dirty side. With a clean reference to front of the valve cover on passenger side.
Crankcase excavation is important to keeping an engine clean and healthy. However, if it only ran for 10 seconds at a time, a simple separator to keep the oil out of the intake from excessive crank pressure will work fine.
Vacuum pumps rock on N/A and nitrous stuff, people are on the fence if they are worth it on blower/turbo stuff. That are really great if you build the engine with one in mind. Not to mention the motor is running under vacuum which means less friction (not friction per se) but the pistons move easier through the bores, windage control (which is an issue on these cars), no leaks, ect. Lots of benefits. The biggest con is they are expensive.

It also functions with the factory serpentine system with all other accessories in place minus AC, which is a big plus.
They also have some excellent tech service, Bill answered all my questions about pulleys and mounting options.
Edit: Oh hey Bill, didn't realize you were on Tech.

I use this harness along with the CEPH-2GT pump along with an
RX dual check valve catch can with my breather on my turbo 3800 drag
car setup.

Only thing I ran into, was had to to up the size of the fuse, kept blowing.
Once I did that its been in there for awhile now and running well without issues.
Setup seems to work pretty well and didn't cause all that much.. Catch can I guess
a bit pricey but its nice

It wouldn't be good for the O2 sensors. It might work if you put them in the Y pipe further downstream from the O2's. I would think you should place them about 12" away from the sensors.
Thats a good point, but for people like me not running o2's it would be a viable option.
