This is a resurrection of TSN. I take no credit for the design/development of this page. I put this up so that Saturn enthusiasts can enjoy what once was. If you have questions/comments please contact me at firstname.lastname@example.org.
TSN has gone through some major changes in the past few months.
We are always looking at ways to improve the site and the forum
needed a major overhaul to keep up with demand. So, what are all
of these new changes?
Several new topics have been added to the forum including, off
topics, newbie, suspension, engine building, Ecotec/Ion/Redline.
Avatar uploading is now functional. All avatars are now hosted
on the TSN server. Before you upload be aware that they can't be
larger than 150x150 and 15k to be displayed.
The site has switched servers and the domain has been extended
Member donations have kept TSN alive for the next 3 years. Everyone
who donated has received a special "TSN booster" rank
under their forum name. Thanks!
All new forum member accounts need the admin's approval before
their account is activated. If you are signing up for a member account
be sure to fill out all information in the profile. Profiles that
are incomplete will be deleted.
Several new moderators have been added to help keep up with all
of the forum traffic. They have been chosen because of their backgrounds,
accomplishments, and contributions to the community. We feel that
this addition will strengthen the knowledge base of TSN allowing
us to better address questions.
What's new with the main site?
Finally, several new classes have been added under the fastest
V list on the main page (lefthand column). Naturally aspirated has
been broken into DOHC, SOHC, and Ion and forced induction has a
new unlimited class.
The swap guide in the download section has been updated. Several
links have been added and fixed and new articles have been added
to the main site.
What's on tap....
So you bought a SAFC, opened the box, looked over the instructions,
and found nothing to help you install it into your Saturn S series
car, right? Well you've come to the right place. This guide should
help you install either SAFC unit into any S series vehicle. More>>
Firstly, having the ability to tune your car is the most important
aspect of tuning. The tools that will let you control timing, fuel,
and boost are the basis for a good tune. Management for turbo vehicles
tends to be complex, but you almost can't have too many aspects
of a setup's function to tune. Yes, some systems are "overly"
complex, but this extended tunability is likely a good thing. So
something that is "overly" complex is likely just a tuner's
lack of ability to tune. More>>
These are serious tuning tools and should only be used by serious
enthusiasts, once you introduce shaved heads, better exhausts, higher
duration cams, and better air intakes, you tweak the optimum cam
timing set forth by the manufacturer. From the factory, cams usually
operate at a conservative setting to meet drivability and smog standards.
Sometimes it seems that the simplest devices are the most difficult
to understand. If you have ever pondered the internal workings of
wastegates and manual boost controllers than you will want to check
this article out. More>>
Very few subjects can start a flame war on any message board like
the question, which is better horsepower or torque? It seems as
if everyone has opinions on how this question should be answered.
With that in mind I decided to address this topic head on to help
clarify everyone's understanding of this relationship. More>>
So you wanna turbocharge your Saturn? Do you want to build your
own turbo kit but have no idea where to start? Are you unsure of
what turbo, what intercooler, or how to add fuel to your setup?
Well, I have am working on putting together a DIY Turbo installation
section. I will try to cover everything that is needed to safely
and effectively turbocharge your Saturn. More>>
An oxygen sensor is the most important sensor on a fuel injected
car. Located in the exhaust manifold of the car, its function is
to compare the difference in the oxygen content in the exhaust gas
against the oxygen content in ambient air. The results are expressed
in an analog voltage signal often referred to as Lambda. More>>
When turbo charging a Saturn car one of the first things to address
is the fuel system. More fuel must be injected into the engine to
prevent the engine from running lean. In order to deliver more fuel
to the engine many people will replace their stock 19lb fuel injectors
with higher flowing ones. More>>
Detonation or pre ignition occurs when the air/fuel mixture ignites
before the piston reaches top dead center. On a turbo charged engine
this is the first and last sign of bad things to come. Detonation
can turn a daily driver engine into scrap very quickly. This article
will cover a few easy ways to prevent detonation from happening.
Fuel is a critical part of any turbo system and if
you're shooting for big numbers you will need to have enough fuel
to meet the demand. Although the stock fuel pump has been proven
to support 300whp I would not recommend going higher than that.
So what do you do when you are seeking to put down some serious
horsepower numbers? More>>
This short article represents a summary of some information
gathered from the internet on fuel injectors. It explains several
more in-depth injector properties that you may never have considered
before. Topics include injector types, capabilities, and atomization.
I bought the DIY wideband kit from Techedge hoping
for a good way to tune my car on boost. I opted for the DIY LDO1
display, DIY WB controller, and bought a pre-built cable. It came
several weeks later neatly packaged in zip lock bags. All of the
components are pre-sorted and labeled. It appears to be a far simpler
construction than the Megasquirt, but don't be fooled. More>>
Every vehicle needs fuel to run. Increasing the horsepower of your
car requires more fuel. The saying, "more fuel equals more
power" defiantly holds true especially in turbo applications.
So, how much fuel can the stock pump provide? More>>
Before we can start programming the AVC-R we need to understand
what the duty cycle does. Without going into the theory behind wastgate
operation here is basically everything you need to know about setting
the duty cycle. More>>
There is hardly a nicer scan tool/software dyno set made for this
tool. It compensates for speed, different gears, and more. You can
even use this setup on all obd-2 cars. More>>
A quick and dirty guide to all the turbo system components needed
to make ~220whp on a Saturn 1.9 L engine. Relatively speaking turbo
charging a Saturn is not that difficult. Time and time again people
have proved that with a limited budget one can build and install
a reliable turbo system on their daily driven Saturn. More>>
