Anyone have direct knowledge or experience about how beneficial or desireable it is to install CT's high volume oil pump when running a blower on an NSX that sees lots of track use? Any negatives?

I am getting one.I had planned to get it done when I go sc but think its viable even without the sc.if you do boneheaded things like me(I am horrible about banging my rev limiter) and hear from whom I consider to be reliable people that it is cheap insurance ,as if you play at redline alot (many of us)the oem pump gears are the first to go.and I have never meet a nsxer that did not do it atleast once. so I think its worth the cash IMHO

I've met hundreds of NSXers, including dozens who take their cars to the track. (I get around.) I've only met one or two who did this.
I believe he was referring to hitting the rev limiter, therefore the phrase "at least once". I don't think you'd have to upgrade your oil pump more than once!
Thanks TampaBayNSX-R for clarification on that.I deed indeed mean smacking the rev limiter at least once.and sometimes like alot of things once is all it takes. IMO

There is no real basis for this assumption. The extra 100 or so RPM should have no impact on the life of the pump or integrity of the rotor in it. The rev limit is not set with regards to the oil pump. It is typically the limits of the valve train and sometimes piston velocity, not to mention the point of diminishing returns compared to shifting as power drops off.
The only common reason I have heard for pump failure is starvation of the pickup while running on a highbank oval. The pump runs dry and fails. If you feel there is a benefit of more volume and/or pressure for whatever reason, then by all means get the pump, but don't do it simply because you run to redline a lot on the street. The OEM part is designed for that and does just fine as far as I know. (Mine certainly sees redline many times per day.) As for “cheap insurance”, it is not all that cheap if it isn’t really doing anything for you.
BTW, one must assume that pumping extra volume requires additional power, however small.
For the record, I was asking about the high volume oil pump, not the replacement billet oil pump gears. Yes, the high volume pump comes with billet gears, and they are larger than the replacement billet gears. Still my question was centered more around the benefits of pumping a higher volume, not safety from over-revving.
