All this talk about the EH stuff like its the most bad-ass you can get, when it has not once been dyno'd to gain ANYTHING. A stock SVT UIM over a regular UIM has though.

Valid point.
scottd60 netted a couple hp on his mildy modded 2.5 when dynoing SVT vs Max EH.
I have both the Max EH SVT UIM and stock SVT UIM on my hybrid that I plan to dyno for comparison.
I think the more mods you have the bigger gain you will see - which in my case might be pretty decent.

IIRC it was like 1-2hp, and he even lost HP on one run. I'll have to look it up again. But 1-2hp could be had/gained between back to back dyno runs with the same setup even. Hard to justify all the hype. :/ I'm very interested to see your dyno results, keep us posted!

What most people fail to see is the fact that non-SVT heads are a bottleneck as well.
There quickly comes a point of diminishing returns with any mods in front of the heads when they are now the restrictive point.
I stated long ago that most people expecting large gains from any UIM or LIM work are going to be disappointed. It takes more then just upgrading one piece of the puzzle to get good results. Every piece needs to be integrated into an overall design plan and don't skip the detail work.
FYI - I'm sure SVT could have asked for a little more time on the Extrude Hone bench if they thought the UIM needed it. Then remember the SVT heads are extrude honed themself and the engine uses a larger LIM & TB to boot. The port size difference between stock and SVT is very notable!
Then take into account that the bulk of the gains from the extra airflow ability are at high rpm. When I put on my max honed UIM my gains were notable above 6000rpm. The stock cams are already dead and buried by 6000rpm. The small low rpm velocity loss may actually hurt the stock cams.

I think you hit on a very important point Demon: velocity is just as important as CFM, there has to be a balance. If your UIM can pass through 1000CFM of air, but its not moving fast enough to fill the cylender's, it'll LOSE power.
The real question is where's the sweet spot?

well you guys answered the question for me...its jus not worth what i once thought it was..the tb maybe..but to notice anytype of felt gains i had to buy a custom chip from adc...so 381+300+100+90,thats chip+svtuim+svtlim+svttb...and i might have picked up 10 or so hp...i coulda bought a 3l for that price..

I did back to back dyno pull(s) with a stock UIM vs. a 98 SVT UIM 2 yrs. ago. Best no.'s were 4HP & 7ft/lbs. My motor at that time was a non SVT Duratec with lots of mods, but stock heads. Stuff like 2.5" mandrel bent exhaust, chip, custom LIM, P&P'd precats, UD pulley, machine optimized 60mm t-body, etc.
I paid $100 for the SVT UIM about 3 yrs. ago....

As a buyer, I would have the purchase cost of the SVT UIM and the EH cost. I can (and have) purchased standard 2.5 UIM's for 25.00 or less. Either way my point is that once you start topping 400.00 for a single mod on performance, you should consider the hp/$ ratio and that at some point would lead you to investing in the 3.0.
Now a question..How much would you be willing to spend on this gents SVT UIM/LIM combo, if you were in the market?
Read the question...if you were in the market. The subject is not what we have but what the UIM is worth. The thread is opened by an inquiry from MYCONSVT.
I am just trying to get back on subject. We have offered our opinions, taken our positions, stated our cases and all but you have put a suggested value on the board.
The value is what the subject is based on. If you were in the market what would you be willing to pay?
