How slow really is when the pump fail ? feel like 100hp or still some power but not 469 ? I always thought will be like 349hp like W210 but some say even less power is that true ?

O.k. for sure I have this pump bad right now... is alot of info but any one have a dyno before / after this replacement? I do my search but no info (Dyno) if anyone, sponsor, shop or wherever have a cm30 pump (in stock) here in CA I will drive 
to swap the pump... of course I will pay for it + pay for install (1 h. labor)but what about Dyno? can somebody, sponsor can dyno before and after? I will take pictures, info, etc. also post all this info... I can do this my self... but is true.... I guess alot of people here wish to see dyno results before / after IC replacement... let me know.

LOL you will literally put your foot down and absolutely nothing happens 
Worst feeling ever. Get a johnson pump and bigger HE if you can afford it, especially if you plan on modding later on

as mentioned before..
installing a CM30 without bleeding your system.. will yield sub stock performance...
very easy to do..
All you need is a plastic hose from Home Depot or Lowes... read the sticky how to do it...
perform bleeding after the car is hot... and bleed for a few minutes..
when in doubt do it again the next day..

You can have a failing pump and still have plenty of power. I just started datalogging and my IAT's are 120-150 when the car is fully warmed up. Still goes like hell but after 2-3 short bursts it falls flat for several minutes. Feels like a weak V6 like some have mentioned.
I put a beat down on an SRT-8 so if you would have told me my pump was bad I wouldn't have believed you but apparently it is. At least my IAT's are out of control. Once it's warmed up it never goes below 150-155 but like I said it still goes pretty hard. You'd need to data log to be sure.

If you wanna run all day long w/ o heat soak and without a box in ur trunk . Here are things you should do
HE, Johnson pump CM30 or CM90 ( bigger CM30) 10% water wetter mix with MB antifreeze coolant , PTE ( Patrick) 150T-Stat, spacers . That is all you need just in case if some1 wannna play you .
