Injecting prior to turbo comp' impellers

[T.F.S.]

Interestingly the extra injector didn't make a lot of difference...I expected in the region of 5-10c drop now we are injecting around 1350cc per min but it was more like 0c-1c. The system is not leaking and I am still wondering why we did not see a more significant decrease , could it be that no more methanol can evaporate into the airstream and I either need to increase water content or add another chemical into the mix?

I believe that 250cc is about the maximum amount of water I can inject into a 2.0 engine at this boost pressure..whenever I have tried to inject beyond that figure on this engine it has bogged or misfired so with a 10-15% water content in the tank on this run it would seem I am almost at that limit already

On a much longer run than normal on a 20c daytime blast we saw temps in the low 40's at high rpm and at one point just as I came off of the throttle a split second before I changed gear temps hit over 70c which again is not something I expected!

Yes I may try this!
