this is my first time playing with timing and below is the numbers from the pos 4 port HPI .21BB I'll be practicing on, I have 4 of these so I can do all the damage I want in the quest for knowledge

• INDUCTION—open 35 degrees ABDC (above bottom dead center); close 41 degrees ATDC (at top dead center); duration 186 degrees.

• EXHAUST—open 81 degrees BBDC (below bottom dead center); close 81 degrees ABDC; duration 162 degrees.

• TRANSFERS—open 67 degrees BBDC; close 67 degrees ABDC; duration 134 degrees

so what way should I go for the HPI to get the most lowend while still giving a little more room on top?

I'm thinking of pushing the induction closing to 55 resulting in a 200 duration and opening the exhaust duration to 170.

Does that sound close?
