Pushing past 9k rpms! Wet sump solution...

1slow370 · 05-18-2015, 03:05 AM

Who knows how much they will end up charging for it. Realistically to go past 9000k rpm and not 8000 you are going to need a lot of work. The oil pump is a part of it but i can see the springs running out past 8500. You also need a minimum of an ati damper properly tuned, new rods(at least rod bolts) a full dynamic rotating assembly balancing, some form of external oil pump, jun stage2 exhaust cams, and manifolds that can actually support. That kindof flow. The guy who bought my old car would only have to put a few thousand more in to get to 9000rpm and 400+ wheel hp. He is dropping it off these week for an oil change and a few more things. Pretty sure he is slowly turning it into a track toy. I am hoping that someday somebody will give me the chance to doa couple of the builds i have planned out. A 7-800whp Supercharger kit, a standalone ecu race car vhr na build, not to mention completing my current project '74-'04 400zx. I have gone away but im not out of the game lol.

As far a dry sumps go, what about removing the battery to the back, and fitting a custom tank where the battery goes? Someone on here roughly said you could get a 8 quart tank in that space, maybe a 10. So 8,500 rpm is that cap for a stock block VHR block before things start breaking? **** I give you shot of helping me build a badass NA Z. Whenever I get to the point of installing a jun cam I was going to contact you to see if there is anyway I could get you out to Florida to install the cam.

the height of the tank is important. the flower pot tanks only work on drag cars, the taller the tank the harder it is for oil to slosh away from the hose in the bottom of the tank. also you need a tank TWICE the size of the volume of oil you are going to run. so an 8 quart tank is only good for a 4 quart system. On a dry sump you check the oil level with the car running and hot to make sure the oil is at its max level in the tank and it should be halfway up a tall tank. if the oil level gets higher then that you will not have enough room to separate the air from the oil as it makes its way down and you will have problems with oil coming out the breather line on the tank. unlike the corvette our cars do not have a 20+ inch deep hole under the battery, its just a wheel.

As for the jun cams do it just don't get the stage ones they are better for FI cars.

It was a GTM/ME part soooo you gotta hunt one down from them. Also the setup i had was racing shiz big bore lightswitch master cylinder, OS twin plate, billet pedal stop, and a tilton CSC setup as well.
