Meh, Vipers just arnt the best performers for the cost. Go on streetfire. Why is a bolt on 97 Cobra with 300rwhp getting within .2 or .3 seconds of a 500hp 05 Viper? As i posted earlier, the Hennessy Twin Turbo Viper made 800hp and a stock Z06 runs the same times as it. The Z06 has 300 less hp and costs over 50k less. And the fastest Viper ever made was the Hennessy SRT-10 Twin Turbo. 225k for 1000hp and a 9.75 quarter. Cant really knock that yet, but im betting on the SS Vette to hit similiar times at less than half the cost and about 350 less hp.

 

I know you out ran one but what about the 4.3L 490hp V8s in the Ferrari 430s,thats really getting it done with a N/A motor.And if a 300whp Cobra can get within 2 or 3 tenths of a Viper,its only because the Cobra's fully set up for drag racing[4.56 or lowergears,drag suspension,slicks with skinnies in front].Or the guy in the Viper is a sorry *** driver.

 

Yeah the motor in the F430s are pushing some serious power. They remind me of the M3 engines, maxed out from the factory. But if dodge had everything figured out, then they wouldn't have needed McClaren to help them the new Vipers engine. Buy hey all is fair in streets and tracks so who cares.

 

I heard it ran a 60 in 3.6sec. Is'nt that only 0.02 seconds quicker than a ZO6. A car with 100bhp and 60ft. lbs. of TQ more than a ZO6 shouldhave more than a .02 difference. IMO when you start getting in the realm of 600hp there will need to be serious suspention,tires,tranny that will be able to hold it to the ground which in turn will keep driving the price up on Vettes/Vipers, not including inflation.Just a few years ago a 11 second car would'nt even be street legal. And now look!!!! I hope Congress does'nt put a cap on Horsepower because if this keeps up ppl will be modding their cars with wingsand coming up with custom airplanes....lol

 

you want efficient?
take an M3 with a a 3.2 I6 and push 333 BHP..... I always thought that was the most efficient power ever

but as far as supercars.... ford has the HP per liter covered like white on rice.... 5.4L making 700BHP

now go ahead and throw, "but it's FI!" at me but that does not negate the fact that it comes that way from the factory and it's VERY VERY efficient... and compared to this viper, the vette is on a whole other level as far as efficient power.....

 

The new civic SI puts out 5 more hp per liter than the e46 m3, and I'm sure there are more efficient that are reciprocating motors. The rx8 motor is twice as efficicient as the the civic SI, when it comes to rotory.

 

woah! I guess that means you should sell your stang and get a SI then!!

my point was the I6has 3.2 liters and lays down more BHP than a 5.7, I'm sure the SI is efficient, but it's efficient and slow
with quickness and efficiency being the 2 deciding factors I would vote the M3 king

 

I left out the part about the M3 dominating either of the other two worse than Michael Jackson in a federal pound-me-in-the-*** prison, but you had only mentioned efficiency. lol

 

OK, i decided to go back and revisit it. The guy with the cobra was not bolt on. He was completely stock except for a set of 4.56 gears. On street tires. He ran .3X slower than the viper did. Now obviously the viper driver sucks. However he does "know how to drive and has been to the track several times before". Basicly what i really want to know is : Why does the viper run such **** times? 500hp and it runs a 12 flat. 500 hp in a Vette and it runs a high ten. WHY? Isnt the viper aerodynamic? Doesnt dodge do anything to the suspension? Does the viper weigh in at 4000 pounds? And if so what the FUC* weighs so much? WHY? Perhaps im just overlooking something, but it seems like the viper really blows.

Maybe im just comparing it to the wrong car. I guess the Ford GT makes 550 hp and runs mid 11's. Thats not too much better than the viper. Maybe GM just completely kicks everyones *** with the new Z06.

 

NO NEW car is 'the best performer for the buck, but in terms of just new cars, then yes, you're right. There are faster more hp/litre motors out there for less or about the same price.

What would happen if Honda made a 3.X motor making the same amounts of horsepower/litre they do in the SI, and then managed to give it some gears with a decent suspension stock?

And then put it into some kind of solstice/miata type car? Mustang killer?
