A "snake" with an all-new skin, the ASC Viper Diamondback is super-light and super-fast. It’s fitting that ASC, which helped the Chrysler Group bring the new Dodge Viper SRT10 coupe to life, would, with the aid of McLaren Performance Technologies, show how the Viper coupe might be taken to an all-new level of “extreme.” The 615 bhp Viper Diamondback features a carbon fiber roof, deck lid, rockers, fascia inserts, body trim and a massive OmniCarbon hood that shows off ten unique trumpeted air intakes, with individual port throttles, peeking through - a McLaren Performance Technologies feature reminiscent of McLaren Can-Am engines of the past. The hood also shows off compression-molded carbon fiber. It’s displayed beautifully, with a broad, clearcoated racing stripe down the Artic White-painted expanse, subtly outlined by “Viper Blue” and “McLaren Red” pinstripes. In all, ASC removed about 85 lbs. of weight from the vehicle - including cutting the weight of the hood by nearly half versus the production model. Taken together with the powertrain modifications by McLaren Performance Technologies, the power-to-weight ratio was increased, resulting in an estimated increase in 0-60 mph time of 3.5 seconds. http://www.rsportscars.com/foto/02/viperdback_02.jpg |
more pictures coming soon in WYST... prolly tomarrow :)
|
But it's pushrods and RWD - so it's gonna be bad handling and slow off the line ;) :P hehe
|
Any clue why the individual throttle bodies are aimed in what looks to be random directions? Oh and the engine has to sound amazing!! But it still needs at least 700hp naturally aspirated to impress me for the liters they seem to be waisting. I'm sure a crazy cam could do the job.
|
Looks more exciting then a Vette.
I think 74hp per liter is not too bad at all. Quite a lot of cars out there which have lower numbers, yet are considered "performant". |
Yeah I was wondering myself why the throttle bodies all seem to pointing in different directions..

http://img451.imageshack.us/img451/9...nam12ug.th.jpg the basics are that the nearest to verticle is going to allow the highest intake velocities... this is one way to speed it up... and with such short runners, im guessing that is part of the reason this car boasts much higher power... more torque at high rpm :) in modern cars like the new M5, and the E39 M5... each intake runner is angled differently under the plastic cover to get both the highest volume, and velocity of air into each cylinder. |
Corvette Z06 by Geiger Cars
The new Corvette Z06 has arrived in the dealers’ showrooms! GeigerCars.de (www.geigercars.de) now offers a sporty tuning program for the top-of-the-line model of the American sportscar.
To achieve a power increase from standard 512 hp / 377 kW to 542 hp / 389 kW there will be soon available the GeigerCars.de STAGE 1 performance kit. The tune-up contains a free-flow intake air guiding with sport air filter, special exhaust manifolds, steel bed catalysts, four large chrome exhaust tips and a special mapping for the ECU. The engine tuning makes the Corvette Z06 even more agile and doesn’t only convince with quicker revving up but also with higher road performances: The sprint time from 0 – 100 km/h is reduced to about 3.7 seconds, maximum speed is increased to about 327 km/h. Many other special GeigerCars.de customizing components for the fastest production Corvette ever are already available. The designers of Europe’s leading customizer of American cars developed a front spoiler edge to fit on the standard apron. The bodystyling part doesn’t only make the front view more aggressive: The lift on the front axle is further reduced. Its aerodynamic counterpiece is a diffuser to fit on the rear apron. To be able to always safely control the outstanding road performances of the tuned Z06, GeigerCars.de offers a high performance brake system. GeigerCars.de also offers suspension tuning for the new supersportscar. They designed a custom spring strut sport suspension, which replaces the standard transverse springs to achieve an even more dynamic handling. To perfectly fill the existing space inside the wider Z06 wheel houses, the GeigerCars.de technicians developed an equally spectacular and exclusive wheel/tire combination. The multi-piece chrome wheels were designed in the dimensions 10.5Jx19 front with 285/30 ZR 19 tires and 13Jx20 rear with 345/25 ZR 20 tires. The GeigerCars.de set of wheels with tires is charged with 9,450 Euros. Of course GeigerCars.de also offers exclusive interior appointments for the cockpit from Carbon panels up to the masterly handcrafted full leather trim in every imaginable color and design. GeigerCars.de doesn’t only offer customizing options for the new Corvette Z06 but also fully tuned cars starting from 93,000 Euros. http://www.americancarfans.com/Tuner...002.mini1L.jpg http://www.americancarfans.com/Tuner...002.mini3L.jpg http://www.americancarfans.com/Tuner...002.mini4L.jpg http://www.americancarfans.com/Tuner...002.mini5L.jpg |
cerious how much im reminded of Spectre Werks :|
i can say im not a fan of the rear wheel width... it looks somewhat ghetto in how much they stick out |
Do they fix the interior?

500ci LSX motor in final development.....
Where will it all end... :shock: :shock: :shock:
I can just imagine the possibilities with a 500ci LS1/2/6/7 in a 3100lb Z :twisted: :twisted: Quote:
|
Sounds good to me...I can imagine what a 500ci LS7 would put out... :shock:

620 rwhp 532 rwtq street tuned LS7 C6 Z06
Holy smokes... talk about an insane daily driven well mannered super-duper--duper car ;)
I almost want one realllllllly bad now... :P Quote:
|
All that with just a cam and exhaust!? Incredible! :shock:
|
:shocked!: :drool: :shocked!:
|
And they said push rods are old tech with no future.. :P
620rwhp @ 7100rpm --- thats about 700bhp... Normally aspirated, 2 valves per cylinder - 700bhp... what other street car has that kind of get-up-and-go without some serious changes being made. Imagine what will happen once they start really working on these motors... ;) |
judging by how many C6 Z's i've seen today... (all different colors... Blue, Yellow, Silver)... i'd really like to see an LG cam+headers+tune somewhere close... that sounds rediculoulsy amazing... hehe, 100hp/liter? :P

7500 rpm NA 650RWHP.... that is awsome :drool: the upcoming multi-lingenfelter shoot should be interesting; im really wondering exactly what is 2001 Z is toying around with. |
How often has he gotta change his rockers, followers, and valve springs?? :wink:
All i know is the 5 litre ford pushrod in the 2 falcons im helping run this weekend has nearly that grunt, rev's to 7500 and needs top end rebuild after 50 ish hours of running or less! |

These are not "old" engines. They are new engines with an "old" design, that turns out is not so old. So you change springs every 20,000 miles... small price to pay for the performance and package you get. And do not forget, ALL the uber exotics with these performance (and less) figures ALL require HUGE maintenance efforts at major milestone intervals.. ;) |
Quote:
The falcon engine is literally a nascar engine (ford racing) just with fuel injection rather than carbs, its an aussie V8 supercar. Its a pushrod too, and as for the question of it producing the same power as a 7 litre, the 7 litre in question is not heavily modified, and the torque curve of that will be a lot broader than the torque curve of the 5 litre, although its still a bit quick in a straight line this thing hehe, bye bye M3 GTR, Porshe GT3 RSR's oh dispatched a DBRS9 at a test day too (not the lemans one the newly developed GT lesser model). 8) |
^^^ Yeah I know - you are one of only 3people outside the US and Australia that undersdtand let alone appreciate the push-rod.. :P ;)
I was refering to the fact that all the super high performance OHC super car engines have really strict and expensive maintenance requiremnts as well, so it's almost a result of the performance level of the engines, not just the design.. :) NOt to mention the 20,000 mile annual valvle spring renewal on a Chevy is going to cost 1/4056th of the cost of the same job on a Lambo.. ;) |
Of course it would be LG leading the way for the LS7. Their headers and cam work for the new Z06 are just about the nicest aftermarket work that I've ever seen.
Definitely not cheap, but the results speak for themselves. Once I get my C6Z, this will be the way I go with it. |
I'll be satisfied when Thunder Racing puts their cam in an LS7, best i've seen for LS1-6. Just out of curiosity, how much more does a C5R block weigh compared to a 5.7?
|
Quote:
RC...wanna take this one? |
hell i would love to make 100hp/ltr. in my pushrod v6 :) 300hp damn that would be insane. not really out of reach if the money and time was there. but isn't that the answer to every car HP question :twisted:
|
Ok found it....
LS1/6 Dressed Engine Weight - 497.2 lbs (226 kg) (manual trans) C5R Engine weight - still can't find it |
Well i've been looking and i still can't find the answer, according to Forza it's only 28lbs. :D
|
The C5R block is essentially the same base block of aluminium as the LS1/LS2/LS6/LS7 - their are slight internal differences and metalurci chanes.. but essentially the same light weight part.
It should be known that the LSx assembly is lighter than the M3 6-cylinder setup.. ;) nth posted the weights one day if I am not mistaken. |
7.0L V8 engine (tuned) making ~700hp......100hp/L
4.3L V8 engine (standard) making ~500hp.....more than 100hp/L. :P |
Quote:
Thats 620 RWHP. With an 18% loss to the rear wheels thats closer to 750hp and the car only weights 3100 lbs. I don't think your 4.3 (in that car) would be up to the task at taking on the Z. I understand that the 4.3 is untuned and I absolutely will recognize that european engine tech is way beyond that over here in the US. Much more power out of smaller NA engines. But I still like the raw sound of that 7.0 v8. And there is also a price difference for those high tech high reving engines from europe. Oh well, each to his own. Wait a minute....what car with a 4.3 are you refering to? If it's not N/A it doesn't count in this argument. |
I assume he is refering to the F430. And what the LSX engines have over those technologically advanced high revving engines is reliability and they're basically bulletproof.
Compare the amount of times and cost it takes to service a Ferrari, but to service something like an Ultima GTR would be nothing compared to a Ferrari and it has the performance that would be compared with an Enzo. |

Nevertheless, the LS series of engines is a VERY impressive peice of engineering, and not only with a nice light 'all up weight' due to the lack of cam-train on the top end, the centre of mass is nice and low too. Also, i'd just like to distinguish that making a pushrod set up as good as these being discussed is NOT easy, and its a testiment to the years spent developing this set up that is pushing very impressive numbers and giving good reliability. However, the majority of pushrod designs in the mass market belong in tractors :P :wink: |

^^ Haha, touchee! :wink:

Yes I was referring to the F430, which of course is an N/A engine. Don't worry just trying to stir some shit. |
Well, this tuned Z06 as a PWR similar to a McLaren F1, so you have to give it props.

good old displacement :D N/A power will always win over a turbo/supercharged motor IMO. but the 5.0L mustang motors are beast they can take a lot of power with min. mods. but the z06 is only going to make more and more euros bend over.

It may have what, 750 CRANK BHP but it still weighs 600lbs more than the F1. As I said though: I give the car props. |
^^ What was the Macca's Nurburgring time? ;) :P
|
^^ it doesn't have an official time, the same that a Murcielago doesn't have an official time.
