    Moar Powah ... Cold Air induction

    So for nearly 30 years I've been pulling under-bonnet (hot) air into the induction .......

    Originally it was quad 45DCOE and more recently 8 x Jenvey ITB downdraft.

    Finally organized an air box and now a cold air inlet from over the top of the radiator after data logging finally working and reveals 60 DegC IAT (why was I surprised)

    Have fabbed up an ali runner per the pictures.

    Now I am concerned that all that cold air will affect AFR, so putting an alarm into the dash if it goes over 10 cos the last thing I want is to detonate the engine

    Sandown this weekend will tell ...

    Keep an eye on your water temperature, that intake looks like it's pulling air from in front of the radiator, which might partially starve it.

    Is running E85 ... target is ~10. Nervous about going over 10 at WoT - Sandown has 2 uber-long straights and all I do is keep pulling gears - engine says flat for a significant time

    Thansk for tip ... Radiator fed from big opening in the splitter/spoiler as well as grille area - and has shed-loads of ducting. CAI takes top 40mm across the top of the grill under the slam panel.

    Now I have a decent dash I've set a water temp alarm of 106 DegC as well. Historically has never run above 100 DegC unless ambient is 35 plus
