I ran the whole 2013 time attack season on one longblock without touching it so we know I had no issues with stock block halves. I'll test the new block in the power range I ran last year for a bit, then turn the boost up once I've given it a thorough run at the same power for comparison.

Same here, never had an issue with stock cases, cooling, or head gaskets so maybe I am not the best person to try and break this thing lol. So far I have just broken rods in the process. BTW thanks Mike for the backup goodies

That just means when something breaks it won't be because you're a bonehead...which is exactly what you want from a test.

And you're welcome for the goodies. You legitimately got them for half of distributor cost, but I'm in clearance mode and I'm glad they went to a good home.

I had a closed deck block (not from Outfront) going strong for a year. 470hp at 100mm bore, will be made into my spare block for when the sleeved one needs a tear down.

I don't get these cooling questions, its not like Subaru has open deck and closed deck headgaskets separately, closing the deck isn't changing the coolant flow at all.

Working on getting some 14mm tool steel head studs to look at as well. Should be interesting to see how they do against the 1/2" studs on a film test.

Have you figured out a procedure for the film test? Or figured out what you're looking for exactly?

You must have at least 3 or 4 different manifold now, huh?

Improvements over stock. Better distribution of forces and higher clamping forces would be ideal, but I think that may be too much to ask for by merely changing studs. I hope I'm wrong. The biggest problem is that how they come from the factory cannot be duplicated

I need my internals before I can do the tests. Want to have it done on an assembled block to be accurate. That means I have 2 blocks I need to finish.

I have a crap ton of manifolds lol. Hoarding them. I have

-Alliance Fab Equal
-ETS Big Runner Equal
-Gruppe-s Equal
-Perrin Equal
-Fobia Fab Fog Light Equal Twin Scroll
-and now the UR T4 Twin Scroll

I knew you had a lot!

Which is your favorite so far? Quality? Differences?

Depends what your looking for. Weight, powerband, etc.

Shes just about ready to race. Swapped out dampers yesterday, put new plugs in, and took a quick spin with the new chassis setup. Boy does it feel good . All I have left is purely aesthetic. Don't feel like putting my headunit back in so I am going to slap a piece of aluminum in there and mount my MAPDCCD there for now. Going to hold off on installing the window net and master cutoff until I actually make some fast passes. Once that happens I will get the stuff installed and go for my NHRA license.

The holes in the EJ22T block line up with the head gaskets to allow for sufficient coolant flow.

Many of the holes in the Outfront deck plate and head gasket do not line up. I'm not happy about it and I'm debating going another route.

Broadest powerband (which is the exact opposite of what you're probably looking for ).

I've been eyeing the ETS stuff but haven't heard of Alliance before.

the holes in the EJ22T block do not line up with the current AVCS heads well, and cause cooling issues. people associate this issue with closed deck in general, when they hear closed deck they automatically assume overheating.

the outfront block has not shown to have any issues, it HAS been run in road racing and time attack applications in the subaru platform with no ill effects.

dumping a motor and going a different route based on nothing more than an educated guess is a little over the top.

I would be more than willing to bet that outfront has collected feedback from their customers on the cooling performance of the closed deck motors. they are on the 3rd version, if there was cooling issues don't you think they would have addressed it?

If you ask, they will be happy to share with you many improvements that have been made, one thing that was under heavy research was the cooling performance, that is a big player in the chosen thickness of the closed deck reinforcement.

others chose to go larger assuming its "better" when discovered thicker actually causes cooling issues.

the ports are barely blocked. given there is more than none at all but its hardly measurable.



why dont you try running the S&R closed deck, maybe it will help your cooling issue

Isn't keeping the coolant around the sleeve the ideal theory? Just saying!

why? so you can heat it up more? the radiator exchanges heat, if you prevent the coolant from getting to the heat exchanger its not going to effectively cool.

The Outfront block is designed for both old and new headgaskets which is why is doesn't 100% line up with each gasket.

Bingo, think about your answer an go back and read how your defending outfront!

Then go apologize to Mike!

But I should add to that heat is exchanged threw the oil; air fuel mixture; **** even the transmission and engine bay.

Mike outfront posted your answer! What issues did you have thermostat not opening? Airbound system?
