anybody want to buy the HKS SLD to remove the speed cut???

just pm me...hopefully by the mid of next month boleh confirm...the stuff will come in by october....for manual and auto....

Didn't you upgrade your oil pump?

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

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

but u do haave and extra oil cooler and pressure = force/area....bigger area..... pressure drop is unavoidable... lol
