Sure it will. Lot's of folks care about reliability and handling over a couple MPH. Most of the ones that object to that are folks that like to talk big on the internet, but don't actually have to maintain these boats!:rolleyes:

Interesting, I was just talking today about building an Ilmor implementation. I still would like to see them develop their own drive. And I still think the company is on the right track, even though they probably still have a lot to learn. They are good for the industry, even though they probably have some more lessons to learn. I wish them well.

These are engine issues, hell it is a chrysler, what did you expect.

How were the drives? The NXT is all about the drives....

My drives were fine ask Nascat about his:( Actually the 700's are important to me because of altitude and temp compensation

Interesting on the power loss. I have found that the Imor actually does not lose any power at 100+degrees vs. the Merc. Maybe you had another issue. Did you contact Imor to resolve your problem? At idle I considered it great. Planning was a different sound alltogether though. I found that from ilde to full throttle the powerband to be unreal. It was nearly veritical throughout and also showed this on the dyno sheets.
Just curious, could you have had another problem?

Im trying to find the article in PB mag where they compared the Ilmor 625 vs the Merc 600. Check out the power curve there. Also I remember there was a missprint in the nexts month issue on the mpg. This is the first negative post Ive read on the Ilmors, sounded like a few things went wrong on this earlier application that soured the whole experience. Jeff
