What are you using for a vacuum source on the cans?


Regardless of blowby, a lot of oil splatter is happening in the valve covers. You want negative pressure in your crank case (testing has shown it actually helps with ring sealing), so you need to suck from somewhere. Valve covers make the most sense.

Remember road tubes on older sbc? lol..

JAZ mini catch can with filter on top on my pass valve cover as well with no issues. It hasn't pushed any oil into it that Ive noticed under boost (none has drained out). But I get some oil in the separator that I dump out every month (just an ounce or two).

Alot can be said of newer engines in need of things that Kingtalon would comment about being incorrect. My stock 5.7 HEMI in my 14 and 18 RAMs have horrendous PCV systems which leads back to piston rings and blowby. The stock PCV system sucks up so much oil into the intake in a short amount of time its insane. They also in stock form run the PCV line back to the filter box which allows oil to be sucked through the entire intake tube (sensors and all), Gum up the TB and intake. I also have a Diablo oil/air separator on my 5.7 HEMI and I literally have to dump out 4+ ounces of oil from it in a months time (less than 500 miles a month). Its actually normal according to Chrysler that the engines loose 2qts of oil in a normal 5k oil change schedule. Again this is NORMAL for these engines even if we dont like it an are not used to it.

Increased ring gaps for BOOST/N20 will cause added blow by and increase the oil wanting to come out of the crank case vapors resulting in a mess if you dont contain it. Nothing wrong with catch cans/oil air separators on these motors.
Probably 80% of the volvo 3.0T and 3.2 engines use about a quart every 1K. sometimes more. couple of times per week we get people in "my low oil lights on, volvo said i can go 10K on oil changes" Whoops.

Re: Going from a single turbo to twins


Well, the new camshaft is in, new timing cover and valve covers. I sold the HSR and bought a new intake and throttle body. I am slowly putting this back together again.

haha, gotta love the OE manufactures. I run extra oil knowing I'm going to loose a bit through the separator.

Re: Going from a single turbo to twins

Just an update...I am waiting on some poly locks then I can reset the valve lash and fire it up again. I have also retrofitted the Speed Engineering 3" dual exhaust onto the car as well. I will post pictures up soon.

Re: Going from a single turbo to twins


I finally have a full exhaust on the car. Speed engineering dual 3 inch and all I had to do was modify the front section to merge with my down pipes. It sounds really nice. And so glad I won't have to deal with the exhaust fumes coming back into the car on long drives.

That is just awesome. Those tips remind me of the Kooks setup. Any sound clips yet...?

I do have a couple clips of idle since the car is on 4 jackstands for the winter. I'll try to post them up.

Was your NX cam a retrofit roller or OE ?

My buddy needs a blower cam for his Vortech LT1 build

I'm running the NX276 and it's a fantastic cam. I actually enjoy driving my Formula with the 3000 stall TH350.

Re: Going from a single turbo to twins

Have you measured how much is ground clearance with speed engineering exhaust?

No, Not yet..The car is still on stands until spring.I don't see it being a problem since I have not lowered the car at all.
