The SLS AMG Black Series pushes out 622hp N/A. With more efficient air flow (simple aftermarket mods, but totally doable from the factory if they weren't too concerned about cost, oddly), you could get it up to 675hp (achieved by Renntech).

 

And the v12 in the f12 puts out 730hp...

But I think the point is that all automakers are trying to consider the path of least resistance to more power, torque, and longevity and it seems like going FI satisfies those directives.

Don't get me wrong--I'd love for them to put the 8 cylinder from the 918 into a road car or find some way to build upon the 9a1 mill as it stands. But it just seems like the tides are turning.

 

Viper V10 has most normally aspirated torque, afaik.

 

I don't think Porsche can put a 8 cylinder in 911's RR layout, maybe they can, but the cost? And even the most expensive 918 only has a 4.6 V8 with 600hp

 

Why not? RUF already does.

 

My dealer told me that there will only be 250 for NA. And, the 200 or so 918 owners get first dibs. The car will be in very short supply if this is true.

 

That would be very strange, putting it in 997 4.0 category and not consistent with historical numbers. I would be surprised and certainly hope this is incorrect.

 

Is that North American allocation for the MY2015 year only, or for the ENTIRE production?
This car AFAIK is intended for additional MYs, so 250 would seem utterly low for the entire run, to include possible 991.2 GT3 RS as well.

I think a minority of the 918 owners will exercise their option for this rugged track car.

It would certainly help to be #1 on an RS list, a good fortune I cannot claim.

 

Indications this side of the pond in RHD are for production numbers similar to the 7.2 RS 4.0

 

Don't believe anything your dealer tells you just yet. Far too early for legitimate information related to these specific details to be out. Expect fear mongering to ensue.

 

Who is your source of info for these "indications"? I hope not the Apollo guy.

 

How So?, I take it you have seen the car, know the full spec, launch date, ect....?

 

As for the nos, don't see why it will not be in line with the out going car, but this time much more demand along with the VIP/918 list, could mean less than the 4.0 RS that are in free play

 

It will be a very tough car to get w/o paying a nice premium. Hey, the 991 GT3 is not an easy car to get right now either. I am hearing demand is really picking up for the Gt3 now that the replacement engines are hitting the ground.

 

Yes, Chevy is incredible - it's LS7 engine w/ 500 hp is so incredibly amazing. Porsche could never engineer a 7.0L engine and make all that horsepower, it's just so far beyond the engineering prowess of the Germans
