Motor Options for new SUPER car!!!

[B.M.F.]

The motor deal is just very hard to swallow and figure out in the new upcoming supercar!!!

Key facts It has to make 780+ hp or it will make less than the new supercharged viper and that would blow...Hell cat is 700hp and Gt350 will be 550 most likely...
1. If its a 6cyl and is $400k+ it better be something really spectacular and still be 780hp+..
2. Vodoo 5.2 fpc motor 550-600Na. This would be acceptable i feel and i would be cool with it!
3. Twin turbo Coyote 850hp... This is the only motor that makes sense for reliabilty and i hear the raptor will have a eco boost coyote in it as there are already several of them running around!!

Here is my strong opinion today.... Its either going to be Twin Turbo Coyote or a Flat plane crank motor'd car. Im leaning towards the T.T Coyote deal.

How can they release a 550hp supercar in the era of 700+hp cars and have it acceptable...The race cars hands down will be a 3.5 eco boost that is a given with the Daytona Prototype program.

What about a hybrid?

 

[twobjshelbys]

To race at Lemans it has to be 5l max for naturally aspirated and 4l for blown. That puts a practical limit on hp.

 

[twobjshelbys]

Hybrid disallowed in lmgt/gte

doesnt have to be a production motor for lemans does it?? because all the Gt's that ran lemans were Na 5.0s built by Roush yates.

 

[STORMCAT]

How about a NA 5.2 Vodoo for the race car and a Turbo 5.2 Vodoo for the street car..:biggrin

I re read the rules last week. The rules used to allow a different engine/trans in street vs race but now it says it has to be closer to street. So I read that you could change internals but not a whole new power train. Maybe someone else could ingerpret. If the bulk substitute were allowed you could do a large v8 for street and a turbo 6 for race. But the way I read it that isn't permitted any more.

note viper gets a bye on its 8l v 10 but the car was in production for many years with that before it was homologated for gte class

man gonna be interesting to say the least come monday...

Na voodoo might be close enough FIA might give it to them. And it would sound right

I am still betting on an EcoBoost V6 with hybrid drive train, combined power could easily be in the 700 or greater range and if it is light enough who cares about the actual number.

"enough" HP is a function of weight. Give us a 2900lb car with 700-ish HP and it will spank almost anything out there.

Most cars now are vastly heavier than that. Plus, if you're Italian you get to lie your ass off about your curb weights.

Ferrari 458 Speciale
Dry: 2,843 lb
Curb: 3,075 lb
Weighed in real life: 3,331 lb

Aventador
Claimed Dry: 3,472 lb
Weighed in real life: 4,085 lbs

I did drive my MP4 over to the scales at one point and with some fuel in the car it weighed about ~3,220 lb, which is within reason given that FikseGTS weighed his around 3,120 with some of the lighter weight options and less fuel. 3,120 is very light for the real world at this point and explains why the MP4 and 650S murder most cars in a straight line.

If you're bringing a legitimate curb weight of 2900 lbs to the party in this segment, you will be beating some asses.

Exactly Kendall.

Curb weight is a huge part of the race car performance equation....

Right up to the point that the sanctioning body puts equalizing formulas to work.

Hey, you're talking race cars. I'm talking the unwashed masses that have to drive their cars on the street.

There's an understatement!

No real power metric for hybrid, and not easily measured/regulated, which is why it make for a such good powertrain solution.

 

[Gene Cassone]

If the street car is a hybrid; I'm out!!
The problem with "italian weights" is that they somehow gain a few pounds making them US versions! The new Alfa 4C is a good example (gains 300lbs!)

 

[dbk]

This is definitely true, but that 3300+ lb Scud wasn't even a US spec car!

 

[Mullet]

it's gotta have a high hp number to sell to the public. The public doesn't look at curb weight....they look at hp.

 

[Matech GT1]

Any race car for Le Mans will be WAY less than 2,900 lbs. The Matech GT1 cars were 2,450 lbs....how does that compare to the street car ?
