This one is a PITA to build, that is the design I based my recent build off of. The next one I build will be a ram horn. I think the ram horn will be much easier to mock up but slightly harder to weld which is fine with me.

 

needs more:

 

That is an interesting design...........

I'm nearly certain that will hang the turbo too low.

 

^^That design won't make near as much power as the longer tubed manifolds.

 

I'd rather have that design than the two shorty bottom mounts that everyone else is posting here. It'll spool fast and flow just fine for my 7K rev limiter and stock block.

I personally like the second design I posted better.

 

Define "no where near".

 

Equal Length vs Log Manifold Test - Tampa Racing

Granted it's not a log manifold, the runners are still shorter...so maybe 10-20 whp

 

see post #52.

 

Cool. So Sav can expect an extra 20-70 hp if I make him a "long" tube manifold.

But...I really like this one. I'm gonna see what I can do to put it in the same spot as my manifold and the other shorty one posted here.

 

I tried making a shorty a while back, but gave up after I couldn't get it to clear the motor mount and/or steering column (with a GT2560). There's just not enough room under there in a Miata







That other manifolds looks like they'd be fun to build though. Anyone want to try an evo twin scroll?

 

No steering column though...

 

You could make it a non P/S manifold and have it moved more stern to clear the steering column.


sorta like this:

 

Or you can do something like this:

 

then you're left without a more optimal collector again....

 

Lets see a shot of the collector.

people would complain about the collector not being in the middle, and filter placement would be an issue if you have headlights

 

people are ******.

 

true story

 

You guys are right, prob not the best setup. And didn't mean to offend or challenge ARTech's or anyones abilities, he's an awesome fabricator. Just thought id share a pic of what someone did to try and challenge the space issue with a similar type mani on a miata.

 

I dont see how you'd accomplish the shorty mani without copying something like the S4 manifold design:
