Electronic Pop Off valve in external exhaust version - plug and play for FCA 1.4 Tjet and Abarth engines - Bonalume ES1

The need to create this new product did not arise solely from the 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 the high pressure and temperature peaks as required, causing it to break and at the same time affecting the performance of the engine both during acceleration and at full speed (power drops during acceleration).
Some problems also occur in the presence of a healthy diaphragm, 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 on 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 features compared to the original product:

• No closing diaphragm, 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° inlet air temperature;
• Completely in automotive aluminum with very low lead content and anodized;
• 360° rotatable on the support bracket, for better positioning during installation;
• IP67 watertight electrical connector and valve/solenoid body;
• Black color like the original, therefore difficult to identify and dispute;
• Guaranteed for 2 years in all its parts;
• Possibility and ease of installation also by the customer user;
• Available for all tjet engines of the group: Abarth-Fiat-Alfa-Lancia.
