Free HP, most everyone knows this but whatever Options

[SlowCelica94]

I'm pretty bored at work. But for you new guys who want some free horsepower, here's a few tricks to going faster. These mods aren't specify for celicas, but any car. Pay attention to if your can is OBOI or OBOII. It changes by year on 6gc's.

~Lighten Interior - When going to the track, for best times and less weight of course, take out trash. If you want to strip a small amount of time here are some things that can be done to take off weight........
1.)Take out seats
2.)Take out floormats
3.)Take out spare and tools(you can wait till you get to track for this)
4.)Be sure you have taken out subs/amps.
5.)Take out trunk carpeting and back seat.
6.)Remove Headliner and overhead power accessories...etc. Weight saved from your top center of gravity is the best weight saved.
CAUTION: Weight reduction can and most likely will move you from a stock class in an Auto-X competition.

~Adjust Tire Pressure
If you find yourself getting a lot of wheels spin on hard high rpm launches try this. Take your tire pressure (probably around 30+) and take it down anywhere from 5-the least you are allowed to run in the given tires. This will provide more bite on cars that need it.

~Free Intake Mod.
-To Remove your Air Intake Resonator....Most are found in the inner fender wall off your front fender. Locate your intake and find out where the filter is. Look to see if connected to a pipe that goes off to either in wheel well or wraps around front of car like a horn.(not the pipe that goes towards engine. When you take out either of these, it will allow more air to come into your intake and if it is taking it from your fender, it will be cooler more dense air. This will allow better combustion and a slight increase in power and more ricer noise. If you install a K&N or other "Drop in" filter at the same time, you will notice an increase in power.

~Parking brake mod for the rally drivers
For better rally driving if you use your parking brake, try this. If you have a normal handle parking brake, push in button and drill a hole across the shaft through the button. Then while depressed, stick a cotter pin through that hole. This will allow you to pull up on the e-brake and create a slide when you need to rotate the rear around. (Not recommended for on road use)

~Slight Ram air
Take dryer hose and run a tube from your intake hole/cone to a free spot in your grill or front of car and have air ram into your intake. It creates about 2-3 psi at 45+ mph.(if done correctly)

~Throttle Coolant Bypass
Very common trick with domestic cars. Take the hose running from the radiator to your intake throttle body and disconnect it and bypass it. The hose on the other side should be connected with a coupler. This will allow your car to run without your TB heating up and causing warm intake air.

~Another Ram Air Mod
This trick has proven to be helpful at the track many times. In many cars you can find the stock airbox/filter location to be right behind a headlight fixture. If you take that headlight fixture out and leave the filter exposed to the incoming air, you will gain a lot more cold air and air to the filter. This has been proven to take time off your E.T. at the strip.

~Throttle Cable Adjustment
There is a lot of slack in the cable that opens and closes your throttle body. This is great for traffic and daily driving. To relieve the slack, you should get a set of wrenches and see the adjustment to the cable where the two nuts are. Well loosen the nuts in the appropriate direction to reduce the slack. Start your car up and check the idle. If everything is good, then go and check for throttle response increase.

~Gut Cat on Pre-OBDII Car
The less exhaust restriction, the better. Unbolt your cat from your header(s) and the rest of your exhaust. Proceed to knock the entire contents out with a screwdriver, a drill or whatever you can find that will work.

~Exhaust Removal
Unbolt your exhaust at your header, or behind your cat. If you want ultimate convenience for replacement, try just unbolting the rear most portion, often referred to as the axle-back portion. This mod will allow for more flow of the exhaust. Top end breathing and power will be gained while some low rpm torque may be moved.

If you break something, I'm not responsible. But if you're careful, you'll be fine.
