Fiat X1/9 twin DCNF cold airbox - part 2

Confess am learning as I go. This is the Mk2 version and ultimately will be a Mk3 but the main thing is to get inlet air temperatures down and stabilised. The twin DCNF conversion, 40s in this case, is brilliant for adding airflow, especially when the head has be breathed on and exhaust too. Airflow = extra power. The irony is the extra power add extra heat and that = less power. Without a cold air inlet box a standard 85bhp X1/9 would probably beat this for top speed. The standard X1/9 has a cold air feed. At motorway speeds can hear this missing due to heat when drive through M25 tunnels. Heat kills power. This car was dyno tested as 125bhp, due to faster cam and wayyyy better breathing. That test was done with the engine lid up but the carbs would still be breathing hot air. Reckon will be good for 130bhp+ with cold air feed. Only one way to find out....
