GT350 gets a new FP350s crate engine

[honeybadger]

So do these motors give you more power sooner than a voodoo? Why is it the voodoo is sort of weak until 3500 to 4000 RRM, was thst for fleet gas mileage? Can a tuner get rid of the sluggish (2-3500) response, or those pedal plug ins (like a throttle booster)?

The Voodoo can make the same peak power #s with the same mods and tuning. As Bauern is alluding to, it really depends on what type of power delivery you want. In highly regulated classes, torque is king because they limit peak HP (huge con for the Voodoo). In theory, the Voodoo delivers more manageable, smoother power.

I still think an unleashed Voodoo with cams and sequential trans would beat an equivalent CPC-based 5.2 around a race track. Power would be more manageable, rev faster, potentially higher peak #s, etc. But who knows

The Watson Racing Sealed Top oil catch can drains back to the Ford Performance road race oil pan. The PCV valves on both the drivers & passenger side are open fittings. This allows the engine to breath better.

The pipe plug on the bottom of the oil catch can is the drain that returns the oil to the Ford Performance road race oil pan. Only need to install a fitting to connect the oil drain line to.

The red fitting on the Ford Performance Road Race oil pan is where the return line from the bottom of the oil catch can returns oil to the sump. No need to pull the oil catch can to empty it.

I thought it was the same engine. Would you mind making a post with the exhaust once everything is all set in place? I wonder how different it will sound from the normal Voodoo

FWIW, I ran this setup for a while. I was told to remove the drain if possible because the oil that comes out the PCV is particularly nasty and not something you want back in the mix. While the FP350S uses this setup, the GT4 cars don't.

I’m using the sealed top catch can. Its not open to the atmosphere.

The vented top catch can is open to the atmosphere. The vented top allows moisture, dust/dirt and anything else access to the oiling system!!!!!

Not exactly apples-to-apples but I have been running a similar Watson racing open vented catch can (passenger side) on my Boss 302 for over 7 years now and it has never, ever had anything but a slight oil residue collect in the foam. No debris and nothing to drain. Am contemplating getting similar for my 350R.

How does it work then? Does it only vent out?

The sealed Catch can vents back into the intake. Same as the production engine.

“The crankcase ventilation system removes unwanted gases from the crankcase. The system usually consists of a tube, a one-way valve and a vacuum source (such as the intake manifold).

The unwanted gases, called "blow-by", are gases from the combustion chamber which have leaked past the piston rings.“

Fair enough. Keep in mind you'll be still allowing some oil vapor to get into the intake. I've been instructed by multiple folks a straight vent to atmosphere system is ideal. But I don't have data to back that up other than anecdotal evidence.

I never understood catchcans. Nothing in there means you don’t need the catch can right?

Well the traditional JLT/FP style catch cans are not vented and only plug in on one side and they will collect oil. A true breather like the Watson Racing/Peterson style is routed to both sides of the engine (mine is mounted on the passenger side next to battery). They are "for offroad use only" because they are not emissions friendly (it removes the PCV).

i thought keeping Pcv function was important? I thought all you wanted was no oil sucked into the intake?

OP- sorry for the threadjack.

There are a lot of threads over on trackmustangsonline about breathers and here is a quick article about one:

No Problem. Trying to share what I did with others. Hopefully it will give folks ideas on how they may want to approach modifying/changing their engines. Good feedback helps everyone.
