Default 08 Hennessey SRT8 Challenger

So last night i got in the new Car and Driver mag, one of many, and in toward the back of the issue was an article on the John Hennessey Challeger. Although not a big mopar fan i do like some of the Vipers Hennessey has put out. I saw the stats on it and my jaw dropped:

VEHICLE TYPE: front-engine, rear-wheel-drive, 4-passenger, 2-door coupe

PRICE AS TESTED: $97,690 (base price*: $95,805)

ENGINE TYPE: turbocharged and intercooled pushrod 16-valve V-8, iron block and aluminum heads, port fuel injection
Displacement: 370 cu in, 6059cc
Power (mfr’s claim): 620 bhp @ 5500 rpm
Torque (mfr’s claim): 650 lb-ft @ 4200 rpm

TRANSMISSION: 5-speed automatic with manumatic shifting

DIMENSIONS:
Wheelbase: 116.0 in Length: 197.8 in Width: 75.7 in Height: 56.0 in
Curb weight: 4169 lb

C/D TEST RESULTS:
Zero to 60 mph: 3.9 sec
Zero to 100 mph: 8.4 sec
Zero to 150 mph: 19.0 sec
Street start, 5–60 mph: 4.1 sec
Standing ¼-mile: 12.2 sec @ 120 mph
Braking, 70–0 mph: 167 ft
Roadholding, 300-ft-dia skidpad: 0.95 g

*Base price includes all performance-enhancing options.

I think these are terrible times for a 600+ hp car. I hope the new camaros dont have the this problem with times. What do you guys think?

Hennessy is notorious for over pricing their packages, but DAMN! 620 hp seems low nowdays for a turbo and intercooler. Oh well the Challenger looks like a fat pig to me anyways. I think an LS3 with a cam, heads, supercharger, and exhaust should be around 620 hp and you could spend the other $40,000 on gas and tires.

After looking at their ZR1 test time(same issue C&D) of 11.7, 12.2 sounds about right. Seems like maybe theyre not the best drivers. Like to know their 60 foot time, might tell us something.

Check out the LS3 vettes with H/C/I/exhaust and youre right around 500rwhp my friend...so with a SC on top of that?! I'd say well over 575-600rwhp!!

I'm bored with that car, challenger had a lot of hype and nothing to back it up with.

WEIGHT WEIGHT WEIGHT. If you want to go fast...go on a diet. These new cars weigh too much.

Hennessey is a jackass, I'd take a stock SRT8 over it.

The only thing you can take serious out of a magazine 1/4mi time is the trap speed.
The E.T. just tells you how well you hooked for the most part.
It did trap 120 meaning if it had DRs it would easily go 11.40 or quicker.
Trap speed=A Sign of its True Horsepower

That's an argument a Supra guy would make.

Actually in the recent GMHTP artical with the home grown 383/Zex Direct port trans am. Some how justified that because his 125mph traps were consistant but still putting up garbage 11.8 to 11.9 ET's was OK because the MPH was so good.



That motor had some top $$$ parts but I assure you if that 6 speed was swapped and a bias ply put on the back at least it would be in the high 10's and still 50K less then this turd, and I am assuming a 30k price tag when the car was new and 20k in parts.... The sad part is the SRT-8 had an AUTOMATIC!!!

I saw that car run a high 11 at his track (Lonestar motorpark). This was at the chevy show with the ls1tech cruise a while ago. I remember asking my buddy what he thought it would run and then we saw the time. I couldn't believe it.

You misunderstood what I said. I wasnt saying it was a good pass because the MPH was good.
Dont get me wrong I think that is a terrible pass for a car with that kind of power.
What I meant is the car has potential to run a good E.T. on some DRs and possibly with a Stall.
I hate those Supra (traction challenged,dyno queen) guys arguments too.

Nice car, but for about $30k less, I could buy a new CTS-V, which in my opinion, is a Much Nicer car and get the same type of numbers!

Then put a Wait4Me tune and a smaller pulley on it and lay the smack down on the $95k challenger!
