The intake tube displaces an internal volume that closely matches most front-mounted turbo systems installed with intercoolers. In simpler terms, a large compressor (the turbo) pushes a high volume of air through a small volume (the intake tube) to the throttle body in about 0.05 seconds with the STS Turbo system, resulting in very minimal lag. On this LS1 system, the mass air flow (MAF) sensor is located in front of the engine above the intake tube. All of the STS tubing is ceramic-coated for long service in all types of environments (again, our system is stainless steel so there is no need for the ceramic coating).   At the front of the rear axle, the STS pump scavenges oil from the turbo and feeds it into a length of tubing that travels up and into the new billet oil cap. The benefits of this are that the air around the tubing serves to cool the oil (both up and back) and since the oil is fed directly into the oil cap, there is no need to drill a hole in the engine's oil pan as with most other systems. The STS patented oiling system provides "wet-start" oiling to ensure instant lubrication at start-up.   NOTES: All turbos have turbo lag; that is the nature of the beast. You can have a ton of turbo lag in a conventional turbo system. Turbo sizing has more to do with turbo lag than the length of tubing. Once you get your car together, you will see that the lag issue really isn't as severe as the text at the beginning indicates. You will find however, that a conventional turbo does have a very violent spool characteristic compared to a remote mounted turbo which has a much more natural HP graph without the near vertical NOS-like HP spike when the boost comes in. Really a positive instead of a negative in my book, and you'll see that as you drive the car. Smooth is always best when driving performance vehicles and a remote mounted turbo is smooth, where a conventional turbo can be quite violent, especially in road racing and street driving conditions. Also, under the hood of a Corvette is almost all plastic so the threat of an engine fire with a conventional turbo is very real. And, the STS systems don't tamper with emissions equipment and pass emissions with flying colors. STS manufactures virtually all of its parts including the turbos.
