Enhance your B58 Gen 1 engine’s performance with the do88 Performance Front Mount Heat Exchanger!
 
Challenges of the B58 Charge Air Cooling System
A common issue with tuned B58 engines is the rapid heat soaking of the charge air cooling system, particularly during track days. High intake air temperatures will make the ECU to reduce power output or put the car into limp mode. Even spirited street driving can prompt the ECU to pull timing and decrease power output due to high intake temperature.
 
Our Solution
It is evident that this system needs increased cooling capacity to prevent heat soaking. Part of or solution is our do88 Performance Front mount heat exchanger. The do88 Performance Front Mount Heat Exchanger is designed to provide increased cooling capacity, preventing heat soaking. It features:
 
80% larger core volume than the original radiator (OE).
Dual-row core that is 48mm thick, increasing the cooling surface by 36%.
Quad-pass layout, allowing water to pass through the radiator four times instead of two, maximising core surface area utilisation.
Slightly higher 5mm ambient fin height (compared to the OE’s 4.4mm), ensuring good airflow to the engine radiator despite the increased core thickness.
Full aluminium construction, complete with durable TIG-welded end tanks.
Increased fluid capacity (2.6 litre more) for optimal heat dissipation.
 
Installation
Our heat exchanger includes mounting points for the OE transmission cooler and both OE rock guards. Some trimming of the OE plastic radiator mounting frame is necessary to fit the larger do88 Performance Front Mount Heat Exchanger (see installation instruction).
