It states on stealths website their pumps do not use a steeper angle. They use larger parts/bore, spec'd to tighter than factory specs.
Plus a lifetime warranty... Don't see that everyday.
Not arguing but from a specialty in hydraulics, usually component failures and fluid degradation happen when a rapid change in temperature are occurring on a consistent basis. Think of it this way... Ambient temp, crank engine, instant shearing, instant constant pressure on all components. Now add much bigger fuel/air than designed for; engine runs hotter in cylinder on startup and usually heats up faster, and has higher demands. That wears out your oil.
It wears out gear oil, hydraulic oil, mechanical components, everything.
I can give an example on my truck: use to drive the highway to work. 20 minutes. Changed oil every 4k(before I was "informed" of said sooner interval). Couldn't tell the difference. Changed address. Now its stop and go everywhere. Motor starts and ten minutes later its shut off; turned on 8-10 hr's later and repeat. Now every 3k I can tell it runs better after a change. Not that it didn't before, but its being used in shorter hot/cold intervals and that takes a toll.
I've been told change oil every 3k miles. Period. If it needs it sooner, these engines will tell you. I can tell on a stock one, and I've been told by members on here even a higher HP engine will tell you what it needs.
Either way get 3000psi to your injectors. How you do it can have an affect on efficiency, such as running twice the surface area(twin pumps) necessary to produce x amount of oil. A single pump will usually be the most efficient because of less drag on a motor, whereas if you go bigger later you will need to upgrade to bigger twins, and it will be more $$ spent.
That's what I would be worried about. Plan it out....
I was never the best at spelling in school..
