STS Systems

The STS oil kit is very simple. The lines goes through your oil cap. You don't need to tap the oil pan. You pump the oil from the turbo, to the engine with a scavenger pump. Their scavenger pump comes with pressure sensors that let off a light and sound when there's a drop in pressure. Shut off the car and figure out what's wrong at that point.

Didn't know that, thanks! Does the send AND return go though the oil cap? Seems like they'd need a really long tube for the sump action if that is the case.

no.. just the return is to the oil cap... the feed line requires a fitting that attaches to where your oil pressure sensor attaches to the block. Basically a sort of sandwich plate.... or atleast thats where I attached my oil feed for my Vortech. Im sure you could get a plate for the oil filter area to feed oil to the turbo also..... And I wouldnt run a line up and dump it in the oil cap if I were doing it.... I would just get an oil pan or tap the existing one.....

I've been reading this post and I have always thought this would be the way to go for FI. One thing that I keep reading from you guys is that HEAT is needed to keep the turbos working at optimal performance, why do you think so? Its the speed of the air moving the turbo not the temperature of the air. Maybe better put would be that the exhaust moves the turbo, it doesn't matter how hot the exhaust is.

Heat is thermal energy. If you keep as much of that heat contained within the exhaust, your exhaust's energy will increase. In turn, the retained heat creates an increase in temperature. Keeping heat in the exhaust is best for turbos as it increases the exhaust velocity.

This statement could not be more inaccurate. Heat = energy, which increases pressure. If you remember the equation from high school chemistry, pV = nRT i.e. increased Temperature increases pressure which is forced through the turbine blades. Heat is critically important to a turbo working correctly, which is why people wrap headers, downpipes and turbos to keep heat within the exhaust system. It's also why cars that have the turbos close to the heads spool faster.

If this were the "way to go FI," you would see car manufacturers, especially at the high end, using it. Instead, you see them placing turbos as close as practical to the heads.

That is not completely true.

While heat does play a factor in turbo function, it's not the most crucial dynamic. The cone effect, whereby velocity increases inside the turbo housing, is much more vital than the slight heat loss caused by moving the turbo system to the rear of the vehicle.

Turbos start producing boost only above a certain exhaust mass flow rate (depending on the size of the turbo) which is determined by the engine displacement, rpm, and throttle opening. Without an appropriate exhaust gas flow, they logically cannot force air into the engine. The point at full throttle in which the mass flow in the exhaust is strong enough to force air into the engine is known as the boost threshold rpm. Engineers have, in some cases, been able to reduce the boost threshold rpm to idle speed to allow for instant response. Both lag and threshold characteristics can be acquired through the use of a compressor map and a mathematical equation.

Outside of operating temperatures, heat is a car's worst enemy.

Oh this post was a quote, lol.

I agree, as long as its a good pump its really no different than an oil line for a turbo in the engine, just longer. Ive had 2 stock turbo cars and never had an issue with them or the oil lines for them and they do get hot.
