What? Or, what if I told you that you may gain 5 horsepower this weekend, cheaper than $20? Generally If I told you you could gain 5 horsepower this weekend, cheaper than $100
I bet you’d be interested, eh?
Well, the good news is, I’m going to explain to you how to gain 5 horsepower this weekend for $-15 spent. Sound too good to be true? Well, read on!
1) Increase the H2O ratio inside your coolant – if it weren’t for corrosion and freezing concerns, automotive makers would use pure water. Water cools a lot better than coolant any day of every week, and a cooler engine can be a better performer.
Instead of half and half, try 40/60. Usually Do Not use pure water, As this may cause premature corrosion and that can be no fun in any way to clean up. You may also try water wetter to further enhance this effect.
2) Index your spark plugs – this is an time tested trick that is good for about 1 extra pony. The theory here is to aim the open end of the spark plug terminal (the gap) to the intake side of the head. In order to do this, simply mark on the plug a small line to indicate where this gap is, and install the plug as normal.
Try to line up the line together with the intake side as best as you can. It may require buying 2 sets of spark plugs in order to do this, but hopefully you’ll be capable of do this the very first time. Be careful with aluminum heads not to over tighten, as that could lead to a costly repair.
3) Relocate IAT Sensor – This can be a very simple modification that will work with a great deal of fuel injected vehicles. The IAT sensor (“Intake Air Temperature”) tells the computer how cold or hot the incoming air is. The computer will likely then adjust the amount of fuel being injected, along with make minor adjustments to timing based on that reading.
However , in many vehicles, the IAT sensor is located in the intake manifold, near to the cylinder head. Therefore, air that the IAT sensor “reads” is much hotter than the air, say, in the intake arm. The idea using this type of mod, is always to relocate the sensor for the intake arm. Use JB Weld or similar to repair the old port for the sensor.
This will cause your computer to believe that incoming air is slightly cooler, causing it to inject more fuel and advance the timing a tad.
4) Synthetic Oil – This really is guaranteed to buy 1-2 horsepower, as multiple dynos over time have proved this fact. Simply by switching to a true synthetic oil this weekend you can decrease the friction with your engine, improving efficiency, and therefore going faster.
5) Insulate Fuel Lines – When your fuel lines travel through the engine bay they heat up. However, cooler fuel produces more power for more reasons than just cooling down the intake charge–although that certainly helps things! So, to enhance power output, simply purchase some refrigerator/air conditioning insulation and wrap the fuel lines with the insulation. While you’re at it, you may wish to go ahead and do that to the intake arm also for even more power.
