Does anyone know definitively where it is best to spary meth into a 5.4L with a TVS for higher octane? I can not find a post that can state for sure pre blower or post blower. Thank you in advance.
Yes use a Hobbs switch. At a certain psi it will turn on.
I can't remember what switch I used on an old eclipse I had but it was the same setup as a Hobbs just a little different packaging. The meth kits maker usually sell one in their kits
