Theory is your guide........ Trial is your best friend
@Rotrex - What do you mean by "That's not how WI works anyhow" ?

I mean with this than unless you inject large amounts of methanol, especially pre turbo like you, IATs won't drop that much. Most of the knock suppression happens due to the water droplets in the cylinder and the high octane of the methanol.
Your system is a bit special, indeed and shows significant drops in IAT. But you also have no change cooler. Your system is optimised to both drop IAT and get mix into the cylinder.
if you inject way less past a charge cooler, not to much IAT drop will happen. Most knock suppression is due to in cylinder effects.
Your install is also a good example what you can achieve with WI given you inject enough. 500ml/min for a 430HP engine in the OP' car is not what I consider a lot.

I am looking forward to some warmer weather to properly test the new bigger direct port nozzles.
Good to hear you car is still running strong.
