just pm me...hopefully by the mid of next month boleh confirm...the stuff will come in by october....for manual and auto....
I would like to sell mine....... but wait untill i remap the ECU first....

Normal...... so is it lower oil temp?? How much??

Didn't you upgrade your oil pump?
If you're traveling on highway, you dont need oil cooler, becos the air is constantly cooling it...... But if you're in town, you will wish you had it....

hahah time for me to put my work to use.....

Actually pressure drop is not entirely due to longer travelling distance.....Poiseuille's Law is what u meant by travel distance is the amount of drag in the in the pipes.... ie....when u double the length of your oil pipes....the pass through rate will decrease by half....but if your oil cooler pipes is 19% larger, the pass through volume would increase by 100%... so if your oil cooler comes with a slightly larger pipes u will not get the pressure lost


one more thing...if you oil viscocsity is increased say by double ( which i don't think will happen).....the passthrough rate of the oil will also decrease by half due to the density of the oil is higher u need more force to push it through....


what influence pressure drop the most are bends and an extra area from your oil to go through...ie...the oil cooler itself.... a simple equation Pressure = force/area
more bends = more drop in pressure

anyways just my 2 cents worth of understanding

90. But I haven't tried it under the beautiful hot weather while stuck in traffic yet.

Only if you travel at night. When you are on the highway in the afternoon, the temp is still 100+~ish. Of course the air is constantly cooling it, but the temperature is around there.

In short, the drop in pressure is normal. Thanks boony

I think the SLD Type III (or was it II) works fine with DSC equipped 8s. Which one is yours boykichap?

So boony, do you mean that if i use slight bigger hose will help me to retain the pressure??? My pressure wasn't that nice.....

80 - 90 degree is the optimum engine operating temperature

the theory is that wif no extra oil cooler(extra area) u change the pipes to bigger one u will not be affacted by presure drop...
but u do haave and extra oil cooler and pressure = force/area....bigger area..... pressure drop is unavoidable... lol

But if i have additional oil cooler and make a bigger diameter hose, will it helps becos my oil pressure can drop to 1.2 bar during traffic jam.....
