Hi,

 

Could someone help me with this please, not sure if this is correct or changes are required.

 

 

1330 - 10:4 compression - Twin HS4 - Aldon Yellow, vacuum advance, Ignitor 2 module.

Ported vacuum disconnected

 

1,000 18deg 

 

4,000 32deg 

 

Just found the Aldon advance curve ans see there is another 2 degrees at 5,000 so looks spot on to me ?

When engines have a higher compression ratio they tend to need less total timing, so your spec engine may only need a max advance of 28-30 degrees. The best way to check this is on a rolling road
