Thanks for all the replies. I hv proceeded with the installation right after intercooler (well before the recirculation valve). So far so good.
Yesterday, I injected 2 litres of water over 15mins at idle (steam clean engine). Wonder if anyone else has done something like this before?
ops:
Also, with 50:50 methanol mix, we should be aiming for 12:1 for peak power.
What is the AFR we should aim for during peak torque? 11.5:1?
