Hey what do you guys think about the DH-racing top mount manifold? Looks pretty interesting and must definaly create power. It is used on Dave Hickman race H22 CRX. www.DH-racing.com creates 20whp without a tune cheak it out.

 

search DH racing and see what you find

 

I herd some bad things about it, like ppl giving him 8k to build a motor and gettin scammed smart ppl. But i wanna know if anyone personally used this top mount intake manifold and how the power gains were.

 

It looks like they just removed the top half of the manifold, added a spacer, and then installed the throttle body vertically onto the spacer.

I don't see how that would help. I also don't see how you would be able to attach any kind of intake to it.

 

Yah that must give so much more flow intead of it coming in horizontally from the one side all intake manifold ports get air dumped right in. instead of coming one by one. And u add a stack ontop of just a cone.
