Ended up having to re-rout the hoses and pump location. Didn't work correctly on the first configuration. Even cut a hose to short.:facepalm: It does work good now. Really surprised how cool it keeps the intercooler in a hot engine bay with no turbo blanket or heat wrap on.:thumb::thumb: Also had to adjust the water/meth for 5psi boost. That mad a difference. :thumb: Had it set to full injection at 8psi boost.:facepalm: Still need to wire up the water pump and fan. Did go for a test run with the water pump hard wired in. :SWEET1::smitten: Looking forward to some track testing with just a 7psi boost spring.:)

Looks awesome Stu. You have put a lot of thought and effort into this build. And it shows. :thumb:

Can't wait to see it run.

What are you doing for PCV / engine breather setup? I've been battling this for several years on these stupid engines and finally built the 'ultimate' setup according to the Arringtion CCV bible. (google it)

That's a very good question Darell. Not sure. To be honest, haven't thought of that yet. Humm......

The truck isn't ready for 10-12 psi boost yet. Will need new fuel supply system, aluminum intake manifold, and bigger injectors. Going to try and stay with this KRC tune. After all, can only go up to 600enghp/640engtq with the Sharadon stage III trans.:sad: Already at 583enghp/629engtq at 8-9psi boost. It is what it is........:ermm:

Unfortunately, this is what I changed from after trying it for the last few years. I found the check valves fail after a few hundred miles at best and actually pressurize the crank instead. I had dual scavengers and any little oil vapor going through them destroys the diaphragm, even with better quality ones like OEM Ford or GM air pump check valves. Moroso ones were crap. I haven't tested my current setup yet, but there are no valves to fail now.

It's just dual oil separators vented to a permanent vacuum source as in between the turbo inlet and air filter. The key is large lines (I used 3/4" ID) and properly performing oil separators that won't gunk up the turbo. Arrington makes a fancy one but I built my own as I deal with them daily at work in refrigeration, big and small. No PCV or check valves.

Every post gets better and better. You FI guys have done a ton of engineering and it shows. Well Done..

Brother call it what you want but it takes determination and a vision to accomplish, not counting considerable resources ($$). Very impressive.

My s/c had a 3/4 line running from the intake vent to the I take of blower and still built crankcase boost once I did the exhaust vents no more issues if setup correctly there is no way for exhaust to come back up if your really worried they have secondary check valves in the lines you can add just saying this is a tried and true method used for years and still today in drag racing

What's the need for fresh air the whole idea of the pcv system is to remove blowby and moisture that's evaporating from the system. Since I installed the vents the oil smells like oil again and not fuely

Either way its up to you what anyone runs for vents. If I need to I still have the blower intake port and a blocked port in manifold I can use of needed for fresh air
