because he said that the next time he goes to the dyno it'll be on svt cams to do a comparison on svt cams this time. :shrug: seems clearcut to me
Will be interesting if they could repeat this same test after swapping in SVT cams.
I was hoping the SVT UIM would do better.
Did you get a chance to test your CAI also?

It was my car used on the dyno. This car has 3L cams, I believe 04 Taurus cams. w/ Joey's CAI setup.
I was going to ask the same thing. :shrug:Okay, correct me if I'm wrong, but it looks like the Mazda 6 manifold run started at around ~53mph while the other three started around ~40ish. So of course it would reach 116 sooner...but for your sake, I hope I'm wrong.

Glad I decided to go with the 3L UIM and now that I got an 04/05 UIM coming.

This all makes me second guess my decision to go with a ported 3L...and the hours I've invested in porting, and the cheap price I sold the 3L manifold for on ebay!
I am curious about the SVT UIM under-performing through the entire mid-range, yet picking up at the top end. This does not seem like a "flow volume" or "plenum volume" issue as this (to my simple brain) seem counter to the good 7K performance. It would seem like there's a "flow quality" issue or velocity issue when compared to the oval port manifolds that were made for the oval port heads. Here we have two inlets with different flow rates (from the short and long runners) being merged in the custom LIM.....Can it be that the transition into the oval through the custom LIM is an issue?
Any thoughts?
It seems like the ported 3L motors (sporadically posted over the years) are averaging well over 200whp (all of the highest N/A outputs are either ported or hybrid) while the full 3L are usually just under 200whp...could this just be that the typical ported 3L guys are spending more time and modding more features?
Why don't people just want to understand the 2.5 intake is/was made for a 2.5 liter engine, its not wise to put it on the 3 liter engine with 20% more displacement...
And lets not even go into the downsides of the setup with the injector positioning...
What has amuzed me over the years were BurritaSVT's and Warmonger's posts... Denying the entire science and engine theories and the claim of the mysterious science of eyeball porting/hogging out intake ports, and mysterious capabilites of visualizing fuel spray patterns to make one better than what already had existed... It was argued over and over and I gave up on even arguing but I guess the results are now starting to show...
Anyhow I'll say it again, if you really want to go with the split ports for the love of god atleast use the proper heads keeping the primary and secondary runners seperate (And yes the more recent 01+ 2.5 heads even have the additional oil drains) so if you really want split port don't go wasting a proper set of heads hogging them out or use some adapter plate chaging injector positions without proper R&D... There is a reason why engineers spend countless hours on computers designing engine systems and not throwing an injector here and there and eyeballing intake setups...
