Hi, I'm new here!

[calvinn]

Hello everyone, I'm new here, and I am also new to car stuff. I mean, I know how to drive one and stuff, but when it comes to people talking about "LSDs" or "Turbos" or anything along those lines, I'm totally lost, I joined this forum after a friend of mine (ninjagaiden) recommended me here. I hope to read articles on your forums and learn about these things, some things I want to learn are:

-turbo
-LSD limited slip differential
-supercharger
-double wishbone suspension
-mcpherson struct suspension
-all wheel drive vs 4 wheel drive

But not limited to those. I know basically nothing... please turn me into a.... well some guy that knows a lot about cars. Thanks for reading! See ya'll around!

welcome, hopefully i have recruited u to a 240sx fan :)

[mrmephistopheles]

read, read and read some more, and when you have a question, search, search and search some more.

Welcome! Hope you find all the help you need here.

Are you kidding?

Well anyway do the search...for all the key words and read.

But, for a newbee, here ya go..

Turbo: It is a device that is driven by the exhaust gases from the engine to run a propeller at very high speed (100000RPM) and is connected to another propeller that forces air into the engine to force the engine to enhanced pressure to give more power. The propeller is actually a turbine wheel like a jet engine uses and is encased in a housing that contains both the intake and exhaust props or turbine fans. All it does is take hot air flow from the exhaust and the same shaft on the other end forces more air back into the engine under pressure. More air, more gas, more power. The entire engine is a simple controlled pump. Bigger pump, more horses as in horsepower and speed.

That easy enough?


LSD, Limitd slip differential.

The engine must power the tires. In an "open" differential, power goes to the wheel of least resistance. A limited slip provides power to both wheels equally...until one wheel is totally impeaded, and then the differential can slip enough to keep binding from happening. When a car goes in a curve, one side travels faster than the other. The outside travels more distance than the inside. If the hub of the axel were locked, the tires fight each other for traction. Limited slip axel gears allow for slow speed turning but lock up under acceleration. What it does is to give close to equal power at 2 tires instead of one.

Easy eh??

Supercharger:


Just like a turbo...but instead of being driven by the exhaust pipe gas (air) it is belt driven by a pulley off the engine like an alternator or the water pump. It is first turned by virtue of the engine turning. Superchargers can also be called "roots blowers". It is a series of interlocking worm gears that force massive amounts of air into the engine without the exhaust having to be there since it is "on" at idel.

Pros: Fast off the line speed. Cons" takes engine power from the crankshaft to work. Effctive but robs power to make power and quite ineffecient compared to turbo. You get a faster take off but it uses 1/9th of your horsepower throughout the rev cycle.

The other 2 questions, consult a suspention expert. I know, I don;t tell. It i reletive to car weight distribution and forces applied. Depends on car demand and what you want the car to do for you.

As per all wheel VS 4 Wheel drive..

All wheel drive encompasses a "smart system" to apply power based on how much weight is on either the front or back of the vehicle. AWD will compensate for driving conditions and power applications.

4WD is normally consider a locked down system. All 4 tires drive full time. Most trucks with 4wheel drive do not have positive traction or LSD in their axels so...4WD can be 1 tire front and one tire rear power depending on conditions.

All Wheel drive normally has a locking axel so all 4 tires can grip when needed and most AWD are smart systems, computer or fluid (viscous) controlled.

So...after all that time me writing this, what do you want to do with you car? Got pics, what car, year.etc??


Hope you understand what I am saying, if not, hang out at a garage for about 8 months and gain true knowledge.

yah, that's all some pretty basic stuff. Bill did a pretty good job of explaining them, i'm sure you had an idea beforehand, but yah, it's good to know what all those are, but to learn how they're applied, tuned, used...read, search, etc. but i agree with Bill, i didn't know jack about cars, then i started working at my Dad's Auto Repair shop as a simple desk puke and have learned soo much, granted most of the cars are honda/acuras, but hangin round a garage is a great way to pick up stuff. heh i know not everyone has one readily available for use,but it's real effective.

Thanks for the replies!

I do not have my own car, its my parents car that I get to drive.

Currently, I do not have plans to mod it or anything, since it's not entirely mine... it's not even a Nissan! :(
