You running a dyno or alternator don’t know if that will make any difference?
I’m running a alternator.
From what I’ve read the coil should see battery voltage at all times. I will recheck mine tomorrow to see if the coil is seeing exact battery voltage.

Just a thought there’s not a voltage controller in the stock Vw wiring that only allows the coil to see 12 volts?
Cause now I’ve wired the coil to battery I have a funny feeling that the coil will be receiving 14.7 volts at some point cause that’s what the battery sees from the alternator at a certain rpm if that makes sense?

Yeah I just checked again and its less than 9v at idle. I guess thinking about it now I should have revved it up to see how much it changed. I believe this is a 1975 engine so it should be an alternator. I don't really know how to tell the difference to be honest.

Alternator

Generator

Alternator is better, but a generator will provide charge at any revs. Alternators have to have certain speed to start making charge.

Edit: in this pic you've got an alternator...

Who’s engine is that in the link?
Was wondering where that got that exhaust manifold from and what size it is

That is just a 1 3/8" old old old header that I cut up and turned, welded, and hit with a hammer 'til it worked.

In a couple weeks you can have that one! I'll just bring it to you! I have a boat! It's not inn good shape either. I found several pin holes and its so thin now that you can barely weld it without blowing right through.

Awwww. That's the worst! So just pull the waste gate hose off and watch your boost gauge!

That’s why one to gain max boost 😁
All my little 1600 can do with this turbo is produce 14.5psi @ 4900rpm so why just the wastegate 😂

I'm in the same boat. I'm not sure I can even get that much boost yet.
