Nitto Pumps Above 7500

has any one run a nitto pump to 8000, does the oil pressure drop in the last 1000

ive run our greddy pump to 9000 and its pretty much the same pump. Stock tomei baffled sump all ok, what sump and capacity are you using?

8.5 ltr, even if you spin the engine up for 1 power run the pressure drops 3 pound after 7k

what sump ? dont post it please pm me. We lost a engine (luckily our own) cause the aftermarket sump we used had the pickup mounted too close to the sump floor.

the sumps one i created, 6 gated deal nothing fancy, the thing has another issue where it fills the rocker covers at the track if you pull it through 6 gears there is no oil in the pan.

what restrictor size in the block?

what restrictor size in the block?

1.5 rear 1.5 centre and 1.9 front as per standard, the thing has done a bundle of racing, but with an n1 pump. i pulled the engine today, and fitted a -12 rear drain but not sure how far to cut back the top end feed, the vtc is still used and the power delivery is 11 hundred revs earlier with it, so i dont want to disconnect it, even with the 6 speed it hopeless at the track with out it. How far can you cut back the oil flow. im only running 70 psi hot.

vent the sump on the drivers side to an intermediate tank with the rocker covers then vent this tank to a regular catch can...problem solved.

have you ever blocked the centre oil feed with hydralic lifters

id drop the restrictors down in size, i tested the rear drain on our engine on the dyno and found it did NOTHING useful... so we dont bother with them.

We drop to 0.95 in the drift 26's and have no issues, the 25's need more like 1.2mm or your lifters start to starve.

so you dont think blocking the centre feed is the go, who is the sydney kid, he posted a chart re this

[fletch rb30]

hey mate, im running the vvt head and had too much oil in the head, blocked the center feed, 1.5 in the back and about 1.4 in the vvt feed.

Solved the problem and no lifter rattles.

over 100psi cold and around 70psi hot oil pressure.

can i nominate this post for post of the year....thanks Trent. Another one who has actually tested this rear head drain bullshit and proved it as such. In a race engine i recommend running 1.2's with a hydraulic head and 1.5 for the VCT, enlarging the factory drains by 2mm...this works well.

LOL yeah but the problem is our race car still has it so everyone we build an engine for goes "i want one too" and we get into the converstion of why we no longer do it

PS i remmebr reading a few months back in a Laptop thread what type everyone was using.... lately i've been having performance issues with mine (read dropping, splashing and incar datalogging during drift mishaps) i decided to bite the bullet and buy a toughbook like yourself... best investment ever.

u gotta admit though paul - having the rear drain in place looks really tough (bling factor) & its another thing to add to your mod list LOL

[XRATED]

+1 for the tough book! In the last 6 years, I've drowned it twice, dropped it in the bilge (i work on superyachts) a dozen times, tuned a 3000hp 4000 series MTU marine diesel with 47psi of boost, seen 16 yachts, it's been to 18 countries, 4 continants, saved my ass in 3 air ports, had me questioned once in germany(thought I looked suss with all the datalogging/satalite gear and a millitary toughbook), had 3 different OS's, 2 ram upgrades and downloaded over 300gig or prn...

oh and tuned my GTR... ha ha ha must have flown off the seat 25 times!

without a hicup!!!

who needs a sissy mac!!!

Hey Trent, how do the trust sumps stack up in your sump testing?

Cheers
