450whp boosted application...



which would be better having (4) -10an fittings or just (2) -12an fittings.

I don't care about how it looks, but I just want to have a efficent setup & don't want to pay extra money for welling more bungs than I need to.


LMK what you guys think is most cost effective & functional.


I decided to go with 2 -10an fittings

 

you should be fine with either..

 

This would be better a question for the fi forum.

 

we ran two -12 on the front of the valve cover and two -12 on the back of the block and pushed the motor to 931whp at 37 psi, very minimal blowby coming out the filters on the catch can. if you only plan on running two, then id definitely go with -12 for the larger volume. the filter diameters were 1", which also plays a role in the whole catch can system.

 

four -12an for me

 

I did 4 -8 fittings. seems to workk pretty well, gotta build the actual resivoir, but you get the idea.

 

2 -12 would be my choice

 

If I was just going NA I wouldn't mind using -8an, but for FI -10an should be the standard.


I'll look into getting -12an
I prefer simple & clean looking bay, less is more.

 

charlie, my setup is not done yet but I opted for 2 -16 on vc and 2 -12 on block. It's cheaper and less cluttered than 6 lines to the can. I built my engine very loose though

 

is it ever? lol

 

low blow.... lol

Paul is Paul..... but hey at least he's not as slow as I am...

 

2 x -12's work great for me 400whp. If you're trying to cut cost then the answer is clear, buying 4 90's and 4 straights in -10 will be over $100, 2 -12 90's and 2 straights will be about $60. Plus all the extra line for 4. The fittings and hose are the expensive part, I wouldn't worry about the $6 bungs lol.

 

great info, thank you sir.


BTW what are those blue things your using to keep your ss lines neatly together?

 

They are just hose and tubing clamps. I have the earls version of these things for my car.

it would be done already all motor like this certain h2b but all motor is just too slow for me :p :p

 

The larger the cross sectional area, the better. This allows lower velocity and should reduce the amount of oil that is blown out. There is no detrimental effect on the motor by having larger vents than necessary.

Maybe instead of using AN fittings, welding nipples on would be more cost effective. It wouldn't be as fancy looking, but with the pressure the hoses see, AN fittings seem like overkill. Plus it would be just as fast or faster to take the valve cover off.

Now, my question is how hot the oil is going to be on a turbocharged motor. Would radiator hose be acceptable or is hydraulic hose or such required to handle the heat and not dissolve or swell? I'm trying to save a few dollars where I can when it doesn't hurt safety or reliability...for example, I bought eBay intercooler piping but got a Precision intercooler. I got a Turbonetics turbo, but I built my own turbo manifold.

 

buy push n lock hose the "blue stuff" and jus us barb fittings

 

Where did you get the adapters for the back of the block?
