Re: Ilmor MV-10's, how do they sound?
 

Hmmm, pretty much the same cubic inches as the 525 and 600. And much more fancy tech stuff than just hanging a blower on a motor.. Not sure what you are saying Hydro? I do agree that the torque through the RPM range is very impressive. If you haven't experienced it, try it.

I agree with the comments that they sound like an indy car. Not as throaty as a V8 at idle. But IMO they sound better when get up to into the higher ends of the RPM range.

Re: Ilmor MV-10's, how do they sound?
 

I think what I am driving at is I like the idea of spreading out the power over 10 cylinders. The sound is fine..you just expect it to be different. All in all 625 HP is way cool.


Paxton has a kit for the engine:

Increases HP 40% and Torque 21%

That's 875 HP and Roughly 700 lb ft of torque.

Re: Ilmor MV-10's, how do they sound?
 

My Father and I put together the first Viper engine in a race boat back in April 2002 ( Miami SBI race ) with a company called Natrix Marine from France. We tested the motor back to back with a Mercruiser 500 EFI and they were with in 1 mph of each other.At idle it was fairly quiet and at WOT it did have a unique sound to it.
Natrix Marine did not have an exhaust system designed like they do now with headers with the Illmor package so it would effect the horse power potential.The motor at that time needed more development but I felt with time and $$$ it could be a Winner.It seems that Illmor have done a great job on this package and they are now performing real well.

Look at the exhaust we were running at the time. :p Everyone would say : "Is that a Viper car engine you guys put in a boat". :p

Jo...an engine from France...did it have a rev limiter at 1500 RPM? French don't like to chance anything.. :D

Re: Ilmor MV-10's, how do they sound?
 

I think I turned it as high as 5800 RPM at WOT.The guys at Natrix are racers and run a Pantera 36' now in the P1 circuit. They figured it would be in good hands while doing some R and D on it. :p

It's good the French like Offshore..there is hope...

Re: Ilmor MV-10's, how do they sound?
 

I have the 625 vipers in my boat, but I have not heard them from the outside the boat, but am told they sound strange in a good way. I know that they have a nice lope to them at idle. The 550's were a little more stock sounding at idle. I do like the hum at 6000rpm. As was mentioned earlier, they are extremely fuel efficient for a 625hp engines. They are by the way only 505 ci
(8.3 liter)

Re: Ilmor MV-10's, how do they sound?
 

I thought the MTI that Chi Town and Candyman rode in sounded awesome. Talk about a reliable combination. Nothing fancy-fuel injection. I think they would be ultra reliable compared to a blower motor. Just my .02 KS

Re: Ilmor MV-10's, how do they sound?
 

I really thought they were bigger....they just seem to make power in an effortless way. The big problemo is trying to compete in a monopolized marketplace.....everything is bundled or volume contracted by "Big Blue"....they own or have a piece of many of the other manufacturing companies...
