Educate me on a 'ramhorn'

 

It's one of the best turbo manifold designs.

Here's his: http://www.ccfabonline.com/displayPr...p;categoryId=4

The runners are long, which prevents backpressure from building within the manifold at higher rpms. Also note it's runners are of equal length. This prevents exhaust pulses from interfering with each other on the way to the turbo. The wastegate placement is also usually good on ramhorns, allowing for more accurate boost control.

Jeff Evans/Full-Race did a comparison of a log manifold vs. full-race's ramhorn. On the exact same setup, the log netted 250whp, while the ramhorn made 300. That's a lot of difference for one mod, eh?

 

Ramhorns are $$$$$$ thou

 

A lot of companies overcharge for log manifolds too.

 

The trick to buying a manifold, is to buy one used. I picked up this bad boy for $400 shipped. In this case, by used I really mean brand new from a private seller. He actually milled all the flanges and cleaned up the manifold with a dremel before selling it to me, it never made it onto his car. Kickass.

Pics.











The manifold is such a nice piece, the pics really don't do it justice.

 

damn that manifold is so sweet. i can't wait until i can upgrade my manifold. i can't wait to see what this build puts out. good luck with it all man.

 

nice manifold i know my custom topmount and 3" downpipe is 1000 bucks

 

^ Top mount. Damn, nice. That IS the best mani design that I know of.

 

dude that manifold is F****** SICK. you got good taste SovXgonna be real nice when it's done!!!
