Its quite a good section on WI history and not information I have seen anywhere else either on line or in other text books, I even have on picture of the TAG 1.5lt F1 engine on an engine dyno with a pretty obvious water injection ring fitted to the the turbo air intake  (4 point injection system).
Me personally from my limited testing I would recommend you go with WM50, it makes more power and cools better in my own experience. |
many thanks - I'd like to see this, if only for the F1 history
Will also be relevant for my engine - on full throttle sustained loads I get scary high EGTs. I lied above - I saw 950 C up the runway at RAF Marham, going up the kemmel straight at Spa I saw 990 C!!! needless to say I used it as a cooling straight for the rest of the day!!
EGT sensor is in the main collector of my 4-branch primary designs manifold. As you can see in the pic above its ceramic coated, as is my sports cat. I've always wondered if these could be making things worse?? May be time to go back to the decat??
