With Turbo and Super charging you can create massive horsepower with vw motors.

Being able to stick with single springs helps a lot with oil temp apparently, I’m happy with mine at .540 of lift

Ive never heard about it affecting temps before. Everything I have read says you need dual springs with anything over 460 lift. Also I had a very reputable VW builder with his own dyno and plenty of turbo builds tell me with my cam that has 430 lift... Well... Here is what he wrote:
"Wrt springs. Even with a milder cam you most likely can´t boost more than about 10 psi before the springs meet the limit. Any more than that and you will need dual springs. Another solution to gain a little more without machining is to buy a set of CB 650 springs and only use the outer spring along with a set of Ti retainers. That should give you room for approx 4 psi more."
I was surprised to say the least. Mine seems fine at 30 psi. Maybe it's not though??!!

there's single springs and there's single springs though ;) mine are a bit fancy, that being said, when i start adding boost i will need to either shim them more or add an inner spring but i'm loathed to :(

Might want to take a look at beehive valve springs, they require no machine work (unless large cam lift) and are very lightweight. Dan Ruddock has them listed on the Samba for $220 plus shipping, I plan to try a set on next motor.

Good quality is getting harder and harder to find.

Beehives are gold.....or gold plated...... :shock: :lol:

I was going to go that route but at $270.00 plus shipping it was a little rich for my blood.

Have a look on stateside tuning’s website at their singles, that’s the ones I use :)
Not beehives but very cheap

I have on the shelf, CB Perf dual springs and CM retainers. I also have a Berg spring boss cutter.

So basically all vacuum lines need to tapped into the intake below the butterflies? As in the BOV, boost gauge, distributor and fuel regulator. Nothing in the carb hat?
Also, I was thinking of putting the fuel regulator in the front above the tank. Making a return line short and simple. I’ll already have vacuum up front for the boost gauge. ???

My end castings don’t have a port. So, I was just going to tap the bottom of the vent mount manifold. Maybe two ports that “T” off.

That's correct. Bout the only thing I remember putting before the butterfly was the wastegate and boost controller. I bought a vacuum manifold to run all mine. I ran one 3/8" vacuum hose to it and 1/4" off of it to all the stuff. I have 5 things that need a vacuum source though.

I’ll be using the internal waste gate for. Plumber to the compressor.
