Is a car repair in my future? For most drivers, having an engine light come on can cause some initial panic. What does the light mean? Is my car safe to continue driving? What will happen if I ignore the light? These tips will help you know what to do when your engine warning light comes on.
The real power lies in Single and Twin turbo upgrades, and the options are limitless. You can either build a mild motor that puts out 450 RWHP all day long with instant boost response, or a 1000+ RWHP monster.
It varies from car-to-car, and the conditions as well as tuning. Most BPU(TM)-only Supra Twin Turbos, dyno between 370 and 410 horsepower at the rear wheels. This is usually achieved with moderate temperatures, a reset ECU (to erase anything bad the ECU may have learned), and often a little bit of high-octane un-leaded race fuel. On the street, power will be reduced, especially in poor weather, but at least 90 percent of the power should be retained.
Drivability is not adversely affected. Interior noise level depends on the exhaust system you choose. Some will make it far louder; some will actually make it quieter. But most are just a little bit louder than stock. But the added dBs are also combined with a MUCH sweeter exhaust note, so it’s definitely worth it. And the interior of the Supra is pretty quiet anyway, so on the highway, it will be VERY livable. As far as low-end power goes, the down-pipe will greatly decrease Turbo Lag. So low-end power and response is much improved over stock.
Now we need to calculate our tire circumference. The rear tires section width it 255mm, and the sidewall’s aspect ratio is .40, so our sidewalls are 102mm. Now, to convert this to inches, we divide this by 25.4, which equal’s 4.015 inches. Now multiply this by two, since we have two sidewalls making up the total diameter, and add the wheel diameter of 17″, and we see a total diameter of 25.031 inches. Now to find out our circumference, we multiply that number times pi (3.14), and we find out the circumference is 78.59 inches, now divide that by 12 to convert to feet. And we get 6.549 feet total circumference.
EFFICIENCY – There is a lot of thermochemical energy in gasoline, but there is even more energy in water. The DOE has quoted about 40%, 50 it is probably much more than that. Most people are unaware that ‘internal combustion’ is DEFINED as: a thermo-vapor process; as in ‘no liquid in the reaction’; AND most of the gasoline in a standard internal combustion engine, is ACTUALLY CONSUMED cooked and finally broken down) IN THE catalytic converter recycling, which happens AFTER the fuel has been not-so-burnt in the engine. Sadly, this means that most of the fuel we use in this way, is used only to cool down the combustion process, rather than using a cleaner and more efficient means to do so.
An important product of the DEF process is the fuel transfer pump. A fuel transfer pump is a component that is used on internal combustion engine device or a car. In gravity feed fuel designs, engines do not require any fuel transfer pump. Such designs require only gravity in order to transfer fuel from the fuel tank through a tube. But there are engines in which fuel needs to be pumped to the engine from the fuel tank and passed on. This is done under low pressure or high pressure. In case of low pressure, it is pumped to the carburetor and in case of high pressure, to the fuel injection system.
Now multiply our tire’s revolving speed, by the tire’s outside circumference, and we find that the tire is covering 18,016 feet per minute, divide that by the 5280 feet in a mile, and we find we are covering 3.412 miles per minute, now multiply that by the 60 minutes in an hour, and we find we are traveling 204.7miles per hour @ 6800rpm in 6th gear. If the engines redline is increased to 7500rpm, which it often is, because of a higher flowing turbo. Then our maximum speed would be 225.8mph, given enough power of course.
