Bonalume E1SWITCH Adjustable Electronic Pop Off Valve Abarth/Alfa/FIAT/T-Jet

The need to create this new product was not born from the sole request for a racing product, but rather from the actual problem of this valve originally installed in all tjet engines of the Abarth-Fiat-Alfa-Lancia group. This, being a diaphragm, does not withstand as required the high pressure and temperature peaks, causing it to break and at the same time affecting the engine performance both in acceleration and at full speed (power drops in acceleration).

Some problems also occur in the presence of a healthy membrane, but with higher turbine pressures (after control unit programming).

In the development of the project we have included the possibility for the customer to choose between three types of air exhaust (open ES1 - closed EB1 - switch both solutions with sound management). So at the time of purchase you can decide the most suitable configuration.

The characteristics of our E1 valve are decidedly very high, which in addition to being totally plug and play in both the mechanical and electrical and electronic parts, has some outstanding characteristics compared to the original product:

No closing membrane, but piston in thermoplastic thermopolymer material for very high temperatures and performance (over 270° so no possibility of breakage);

Low consumption and very high efficiency electromagnet (opening and closing times reduced by 20%);

Guaranteed and tested operation at 3 bar with 170° incoming air temperature;

Made entirely of automotive aluminium with very low lead content and anodised;

Rotatable 360° on the support bracket, for better positioning during installation;

IP67 watertight electrical connector and valve/solenoid body;

Black color like the original, so difficult to identify and contest;

Guaranteed for 2 years in all its parts;

Possibility and ease of installation also by the user customer;

Available for all tjet engines of the group: Abarth-Fiat-Alfa-Lancia.
