I was referring to honda pumps, unmolested of course. :P

I always molest my stock honda oil pumps...sort of a by-product of my years at my old race shop. Usually end up porting out the pumps a little, and then increasing the spring pressure on the release valve. Mostly I do it for high rpm usage. For every 1,000 rpm your bearings will require a minimum of 10psi of oil pressure. That being said, most stock honda pumps will supply between 15-20psi/1000rpm, that is until near the 5-6,000rpm range. I just don't like the fact of having 74psi at 8,500rpm, so I do some work to the pump to be able to see at least 85psi at that rpm. Granted there will be some friction losses, but I usually run either 10-30 royal purple or 10-30 redline synthetic. Boosted motors I jump up to 15-40, but most boosted motors won't see a constant 8500 abuse, so I usually just do a quick porting job to the housings and call it a day. And I usually clearance my bearings a hair on the loose side, so I can load the crank right away...which is why I run at higher oil pressures. As for the idiot light...by the time you see it, it's too late anyway. At least with the mechanical guage I can see a steady loss and notice if something's not right before serious damage is done.

API is really making this the very few oils to use on these apps

Do explain? I absolutely love Royal Purple, but the cost is way too high for the average joe. It works very well for the daily driver/quick track scene, but in all honesty, constant high rpm abuse (such as scca track type events) tends to break it down too fast. The last soloII event I participated in I changed the oil before the event, and ended up changing the oil after the event when I got home. :P And at almost $10/qt by me in northeast PA, it get's expensive.

HAHHAHAH ok #1 im ------ stuck in green bay, Wisconsin after getting kicked out of school in orlando, fl. and orlando KILLS the car scene up here, and socal is off the chart. i did the website for beyondredline, biggest import shop in green bay http://www.beyondredline.com look at it, they're all proud that they finally got an awd dyno like 2 months ago, worthless. as far as nice cars up here my buddy has a evo with standard bolt ons and factory 17's and people drool all over his car everyday. he had to join a club in Chicago because the sponsorships for clubs up here are bullshit like Meguiars and other cheap ----. post up the pics of you driving all these cars mr. cheeze ---- because there isn't a nice car on the road in this ------- state, esp now since it is icy and the roads are covered with ---- that the state can't even afford to plow.

And for the fake ***** your bitch prob had a $4,000 job done 4 years ago in mexico, nowadays spend 8k and I know you can't tell the difference.

He has a red 88-91 four door with tuenarboi rimz and a single cam with a blown headgasket because he can't afford the $22 one commands at Honduh.

This was obvious from his first post, why ask him to prove it? No one here cares.

after so much words exchange here and there, i still dun believe in maxing out injector to reach max hp. are we talking reliability or posibility here? maxing out injector most likely will shorten up the injector life spend as well. on high boost, u wun even wan a miss injector cycle which could spell out disaster

im opt for bigger injector solution though

240cc injectors are gay anyways. Upgrade to at least 450cc DSM's if your going turbo.
