I've put in the 7 psi springs (smallest I could find in the boxes) :-)

I did not even know that you could fit springs from a ballpoint pen in a WG. You learn something new every day....

Better to be blown than to suck!

:lol: :lol: :lol:

Slow steps mate: not all safeguards are working at the moment, wastegates are not plumbed either and I am not using E85 as a fuel, but regular pump gas...
It will also be the very first drive out for the car on turboboost, so forgive me if I am not boosting the snot out of it right away :wink:

I would be very happy with a baseline. With 0,5 bar boost, it would be easy to predict where 1 bar boost would end up... :roll: :mrgreen:

Looks really good! Still going to use water/meth spray with this one?

That is one of those safeguads that is not attached at the moment.
I also noticed I had a strange short in the injector where I had hooked the brains of the aquamist on to, so I removed the power of the unit alltogether.
Can't get ahold of Aquamist for a new unit or discuss the problem I noticed...

Thats super frustrating! I'm planning to hook up my HSV to an injector channel like the Aquamist design. I've been pulsing based on a duty table. I want the linear nature of pulsing based on an injector channel instead of attempting it with the duty table.

No, there's an extra AN10 breather on the other side, taken from the top of the original breather box as part of the horizontal set-up. I run dry-sump, so I actually don't need much venting, if any at all. Since my DS tank is in the front and can't connect them to the top of the tank, I vent to a breather box in the engine bay. It runs easy over 7,5K, so some extra venting seemed wise, but maybe not needed. So far, so good though.

Just finally got the parts in to connect the twin spark!
This was the most rewarding thing to do all year so far :mrgreen:

You think? :lol: :lol: :lol:
Waiting for some extra small diameter 'vacuum' line to connect everything else, but should be done by this Saturday. Fingers crossed.

.................. Saturday for a run on (very) low boost..
Sounds like a good idea... dyno it first on WG base pressure which is approx. 22psi and take it from there.

:shock: :lol:

Wanna see pics of that!
