Another manifold test coming soon! FiD-turbo vs MAP

**Goat Blower** · 01-30-2011

Geez, is that what the exhaust ports on the X head look like? The flange holes transition looks like absolute crap in the pics, hopefully it looks better in person. But in the end, the dyno doesn't lie, so that's what it's really about anyways. I think MAP's going to win this one hands down.

Yup, they are square just like the flange. Like I said, the MAP mani wins when it comes to smooth transitions from the flange to the tubing and back.

That might be kinda important.

Big and pretty don't necessarily make power.

True. I found a dyno comparison on evom, looks like it makes 15whp more than a ported stock mani, apparently it does better than I would've thought.

Small and ugly isn't always a great combo either

I saw this manifold first hand, while it would be acceptable by most standards it simply isn't finished to the degree we require. It will be interesting to see the results regardless.

Hopefully this isn't getting off topic at all, but did you guys ever test your mani again aside from Scheides car? I ask because you seemed to think at one point that the dyno runs were started at different times making it look laggy? It looked like it lost 400rpms or maybe 300, but enough to question since you did use 1.25" runners which should be minimal lag.
