Have you used/seen the OZRACE mech pump used Struggler or are you just saying that their NOS system works?

I had one of the OZNOS pumps on my supercharged/turboed 308 years ago. It was more than up to the task. Rob Madden (OZNOS owner) has even used them for methanol fuelled engines and they worked fine there as well.

I also have a lot of experience with their N2O systems

Over the years I have used a lot of their products and have never had reason to complain, plus they are contactable by phone 24/7 for tech support. I also like to buy Australian wherever possible.

Here is some more info cut and pasted from the OZNOS site (which is a bit outdated).....

Holden V8 Mechanical Fuel Pump
Because there has not been any Drag Racing Competition Meetings being held in
New South Wales since 1997 we got a bit bored; so we have ventured into Speedway, don't start yelling, we still support and love the straight line adrenalin rushes but needed something to keep us ocuppied till the Sydney Track is built.
Early in 2000 we purchased an AMCA Nationals Car, these run a Holden V8 engine and as we could not find a mechanical fuel pump that would feed enough methanol we decided to build one to suit.

This High Volume/Pressure mechanical pump (Part Number 42530) has been track tested and proven more than adequate. It has also been popular with the showcar people because of its good looks. The kit includes everything except the
original top housing, pump arm and spring. This kit will deliver 6 P.S.I. of fuel
pressure through the comlete rev range, so no regulator is required. The beauty of a mechanical pump is the more you rev it the more fuel you get.

We do not list a flow rate as there is no set industry standard (set RPM to measure the flow rate). If we measured our flow rate at a particular RPM, the next person could say their item was better by measuring it at a higher RPM. Rest assured that our pump has been track tested now for well over twelve months and being used by a number of racers with more than adequate results.



FWIW it is $285 on the website.
