March Superturbo

The March Superturbo (ST) was an automobile made by Nissan Motors from 1989 to 1991. It was based on the EK10 Nissan Micra, and modelled after the 1988 Nissan March R.

Outline

It was a homologation project for the racecar, and was a daring move, placing a 930cc car in the 1600cc class; it was restricted to this displacement because it had forced induction.

It shared the MA09ERT engine with the March R rally car, generating 110ps at 6,400rpm and maximum torque of 13.3kgm at 4,800rpm. It was among very few cars, others including the famous Lancia Delta S4, and the 2006 Volkswagen Golf GT in having a supercharger and turbocharger installed as standard, and was one of even fewer standard production cars to have such an arrangement.

It combined high-RPM power with low-RPM torque, providing a well spaced powercurve that suited its intended purpose admirably, delivered with a viscous LSD system to the front wheels.

All March Superturbos were equipped with electronic fuel injection (EGI/ECCS), as opposed to the standard K10 Nissan Micra, which was fitted with a carburetor.

They had a carefully minimised interior and no power steering, owing to a lack of space in the engine bay.

Explanation

The MA09ERT engine: MA10ET, and the basic structure is the same four water-cooled series cylinders OHC, and is V type valve arrangement crossing flow Shaiki port, and hemisphere type combustion chambers. The fuel jet system is a sequential injection. The supplement one's salary system has the maximum feature. "Double charge" of supercharger + turbo-charger.

This compound supercharger system is the first in Japan as a car on the market. It extends from the low rotation region to the high rotation region to the whole area, and it can be called an ultimate supercharging system that obtains a high torque and the high response. That is, SC chiefly improves supercharging, a low-speed torque, and the response in the low rotation zone where TC doesn't work easily and the acceleration performance of none is drawn out at the time lag. On the other hand, TC brings supercharging in the high rotation zone and a charge high torque and the high-power are brought. This both smoothly connect with the by-pass control valve, and demonstrate the effect of supercharging in the maximum. It is an overwhelming power performance and charm as for the driver.

Max power 110ps/6400rpm (NET value) Max torque 13.3kgm/4800rpm. The output for each liter marks indeed 118ps.

Moreover, the power weight ratio. (A high performance car in the numerical value in note and car heavy ÷ outputs by small the numerical value. About 8.0 : in the sports car type.) Peel 7.0(5MT floor car of "ST". "R" is 6.72.). It might be a thing to know height of potential and an excellent movement performance even if this data is compared.

Five manual transmission cars of Frontobiscas LSD: ST equip normally Frontodef with LSD with Biscas coupling. The Biscas coupling controls the transmission degree of the torque best by the composition and the viscosity of this oil with a lot of thin plates and the high viscosity silicon oil. For instance, Biscastolc is transmitted to the low rotation side according to the rotation difference even if the rotation difference is in a right and left circle of the reception desk when a hard cornering is compelled. The torque is distributed again and a firm grip as for the road. The power cornering when it is on is not Doriftoouted easily, and the limit performance is improved. Moreover, because the rotation of a right and left circle doesn't change suddenly, the steering wheel is never taken and posture is steady to the low μ road (snow road and road that gets wet and is slippery) and running. It is possible to run through by a linear steer sense.

The suspension with the stabilizer: ST prepares Sas that potential to answer the advanced power performance is high. It is reception desk Strat type independence, and rear is four link type. The back and forth circle does both stabilizers, and installation (Only rear: "R" and "Superturbo") stabilizer prevents the body from rolling with the device that controls the shake and the inclination of the body at the time of cornering, and does working that improves the control stability when high-speed running. In addition, do the tuning of the spring constant and the Bush kind best. It is a suspension that demonstrates light footwork under all the running situations.
