new 800+ horsepower Ilmor engine?
 
Recently saw a post stating that Ilmor will be coming out with an 800+ engine by the Miami show 2012.

Anyone have any additional details about the engine and the rumor in general?

I personally volunteer for testing... will even be so kind and drive to get them at no charge :D

Mee too. I'll test european conditions for free. Just put them in a good test bed, like an Outerlimits 43SV or Skater 388. I'll spend looong weekends and holidays just testing testing testing. Free labour, what's not to like???

Dont think they'll be out that early. If they do come out they'll most likely be in an Outerlimits.:D

An SV29 with an 800+ hp V10 surely would be sweet and different:cool-smiley-027:

Getting to 800 hp from 725 is a little over 10%. Given that the engine is 513 cubic inches, would it still be a normally-aspirated engine? Adding a blower for such a small gain doesn't seem worthwhile, but getting 1.56 hp/cu in is pretty strong. Maybe it's being done through more rpm?

Alexi at boostpower can accomplish this N/A at the same RPM level but at a high cost.

IF these mods are "institutionalized" at the factory the cost would likely be much lower.

When all is said and done it seems that this is not the right platform to start with 800HP N/A as a final goal.

As a full rebuild when tired maybe, but a large cubic inch BBC would cost way less to achieve a good natured 800 na horsepower.

Had the same thought. Maybe something with variable valve timing like the 650, or a forced induction 650 style deal.

We'll see I guess. Those Ilmor guys seem pretty clever.

I think the 725 is it for N/A. The drive will handle 1000hp so I'm reasoning no significant engine upgrades, VVT or 4 valve as examples. That leaves forced induction for cost and minimal engineering qualification. I would speculate 850-900 HP supercharged. Minimal cost to Ilmore.

Now if Fiat wanted to spend boat loads (no pun intended) on new multi valve heads...for the Viper V10, well thats a differenct story. Especially if they contract Ilmore for all engineering design.
