I need to know when my vtec should should cross over and what rpms is best acceleration,

 

try it at 4800 rpm then 5000 rpm then 5200 see what it likes the most. on the E motor its not like a night and day experience.

Also if you have a y8 head somewhere with the single solenoid setup you might enjoy this setup .

But if you can get stock ecu ( that comes with that motor )to work , it works great in the fun deparment and mpg department.

 

~3k for the first solinoid (12V to 16V)
~6k for the second (low profile 16V to high profile 16V)
