Re: Water/Methanol Injection for JTDm
I use water meth inj.
A chap had a vectra 150bhp 1.9 ctdi - you know the engine - the dyno proved 20bhp increase whn running pure mth.
best to run 50/50, I often run 75%meth.
It can make the turbo spool loads quicker, if you inject at full throttle 7psi.
Its all about how you wire it up.
I have not proven this yet - as my car is off the road and in no hurry to get back on it - it may cause overboost probs, as that much eth is a fuel in itself which causes the turbo to spin faster (more fuel going through the engine), as I say, I have not proven this either way yet.
