Ok yes I understand 3 vents now... but there is indeed 2 vents before right? PCV is one, and the one above the cam sensor the other. So it was 2 and is now 3 with the added dipstick port.

Are you just not counting the PCV as a crankcase vent because it is closed on boost?

Dave does your kit include a fitting that replaces the stock PCV valve?

 

I haven't driven the car in the cold winter months.

I explained the PCV/vents, done with that subject now. The horse is dead.

Yes, the kit will include the fitting to replace the PCV, they will be machined next week, the drawing is being dropped off in the morning.

 

Sweet put me inline for one.

Dave would you reckon the tube diameter is more than enough to deal with high boost etc..
I know most guys run huge pipes is there a benefit to going so big?

and another problem, what about us poor RHD drives guys... we got brake booster in the way.
Suppose we can move it to the right of engine bay and just make sure it sits higher than the dipstick drain hole.

awesome......
nice Mr Buschur..

 

Looks alot like the Crawford design

 

The RHD market isn't a huge part of my business, never thought about it to be honest. The can could be mounted elsewhere, as you said.

The larger the holes in the valve cover the more crank case pressure you can vent. If your engine doesn't have an excessive amount of blow by you shouldn't have a tremendous amount of pressure to begin with. I am not willing to drill large holes in my valve cover to put larger vents in. Part of the thought behind doing two valve cover vents and returning it through the dipstick was to get 3 vents. The top two are 3/8" and the lower is 1/2".

Under boosted conditions the car only has ONE. The PCV is closed under boost, so all you have is the factory vent which is 5/16".

 

ye well it no Biggy!
we can just relocate to the other side with longer hoses so it not really a problem

so in your eyes, the huge hoses are really necessary if you not running 45 psi.
and with your you gonna have 3 breathing instead of the crappy 5/16.

still looks top dollar Dave.
I want one

 

I am running 41 psi of boost on my car, at 33 psi when I did the initial testing there were gains on my car with the catch can even at that boost level.

 

Just put it on my tab at Harry's....er, David's

 

cool
but how can breathing the engine better net more power...
I am a bit confused but excuse my ignorance
care to enlighten me

 

I think the gains are from less resistance when the pistons are moving down the bores. If there is excessive pressure in the crankcase then that is resistance against them moving down. Not sure though.

 

The catch cans are available on the site or by calling us here at the shop.

Here is the last part to the kits. This is the new fitting we had built to replace the PCV valve. It presses into the valve cover just like the factory PCV does. This give you a straight port to vent the pressure through and makes the routing of the hose clean and straight.

These are available seperately too for anyone that might need one, $29.

 

David like you said its up to the customer if they want to drill the valve cover and such.

I thought of an idea. The new fitting you just posted for the pcv removel is awesome. But maybe you can make an option on that instead of the nipple part you can have a 6an threaded part on it. Like the best of both worlds. I don't know its just a thought so some of us don't have to drill and tap that part of the valve cover.

 

bump

 

I have no desire to make that fitting in a -6. There's no need for it. -6 is 3/8", the fitting is 3/8". I'd sell 1 fitting if made it in -6.

If it's a custom job that you are trying to accomplish then sometimes you have to just bite the bullet and pay the big bucks to have custom parts built.

This seems to have worked pretty well so far and my car is pretty fast (haha) so I don't know how much more extravagant it needs to be. I can't see adding the weight and expense of -6 AN lines to something this simple, makes no sense to me.
