Thank you for your video presentation. So refreshing to hear an Australian and without any head-banging noise in the background. Very welcome change to the loud-mouthed idiots who cannot string two words together in a sentence or need to yell at you. Cheers
The vacuum is still present from the vacuum port. It's just below the Ventura and isn't effected by the turbo boost. Below the thottle plates is effected .
You need reduced timing under boost , and advance under light loads and vacuum , how your ignition needs to work depends on the size of turbo and the transition between these two zones
How long is piece of string, turbo selection depends on gearbox ratio, capacity, driving habbit, it would be hard for me to recommend what is best for your build with so many virables, 👍🙏
So if I have a vacuum advance only does that mean that I can run a regular distributor and if so would I plumb the vacuum line pre turbo or after the turbo
You can run a regular distributor with locked weights , as soon as the vacuum line see's no vacuum it would have no effect on timing , as there will be a base value locked , hose postion is the same as stock
no benfits to N/a unless your using NOS , ignition curve / advance is needed on a N/a motor to help reduce temps , under boost it's not needed as the ignition needs more time to light off and burn

Thanks
Glad you like them!

i was thinking i was gonna buy a 123ignition distributor will it work well with a turboed setup, if so should i get one with vacuum advance or without

What year Subaru would you recommend pulling the turbo from?

Hallo from the U.K. Would this work with a blower too? amr300. Thanks Grant
Ignition timing yes , carby would stay the same jetted up for your application
How is the maximum ignition timing for 1 bar ( 14psi ) of boost on 1600cc ( all oem engine ) VW bug ?
depends on your boost curve and dynamic compression , 18-21 deg to start with should be safe

The vacuum port is just below the Ventura and will not be effected by turbo boost.
Are the any benefits to doing this on an N/A motor?

hello, any advice about how to make the timing for a vw bug Fi engine to retard on boost? can i use an electronic ignition distributor and modify it?
Hi Carlos ,you can use a electronic distributor you will need a MSD programmable ignition add on or even a CB programmable black box
