Where are the 580-600 hp Vipers at?

[black mamba1]

I know everyone is waiting for the new Gen IV 0-60 and 1/4 mile e.t. But we should be able to approximate the numbers w/in our group. I have 580 hp on my SRT 10, but I've never tracked the car. Any of you guys w/ 580-600 hp running better tires got 1/4 times you wish to share w/ the rest of us?

Its going to depend on driver and track altitude and conditions. So now matter what #'s people post it's no direct telling of what 08 will produce.

I have about 560 hp and ran a 12.5 in Vegas for VOI9 then ran again back in California. Ran some 13's while cold , then later started running 12's and finally consistent 11.7's. But I was on runflats. Ill be going to track next month to try out the PS2's. Then there was a guy in a new Z06. Should be running low 11's right?? I mean the mags say it does it, guys on internet do it. Yet this guy was able to get a best of I think a 12.2 that day. I beat him in his new Z06 everytime except once when I spun bad off line and ran a 12.5 to his 12.3. The rest of my 11.7's made his 12's look bad. But its all driver and conditions.

I think somewhere at some track with right day, hour, driver and conditions the 08 may run a 10.999 but I think most mag testers will have it in the low to mid 11's. Tractions will still be the biggest problem as well as the right conditions and driver.

1) I'll bet the 600hp 'rating' is a conservative number
2) as stated before, the new rear diff and PS2s will help the hook-up
3) the higher (6250?) rpm redline should also help with the 1/4 times

all together, it could be a much quicker car ... more like a 625hp '06 with a quaife diff

Excellent info guys! I need to time myself in the 1/4 mile asap. I have approx 580 hp, and just got my PS2's on last week. No more wheel hop and much better traction! It is surprising the Z06 was so inconsistent w/ its nanny (oops) I mean traction control. I do think the overall balance of hp, PS2's and higher revving motor will make the 08 pull some really impressive numbers. Lets just hope all the advertising $$$ GM pours into the mags does not add a few tenths of a second to the 08 Vipers real stats!

The key to running good 1/4 mile times is getting a good launch and nailing a low 60' time. The current Gen 3 is very difficult to launch well. I have had 20 years of drag racing experience and still couldn't come in under 2.0 seconds on the 60', which is terrible by drag racing standards.

With it's adjustable suspension, improved rear and better tires, the '08 should prove MUCH quicker off the line. I would guess that an experienced driver should be able to get no worse than 1.6 to 1.7 on the 60'. Even if the hp stayed the same, that would shave about 1/2 second off the current 1/4 mile times. With 100 extra hp, low 11s should be easy and high 10s possible with a top driver and favorable conditions.

Just me .02 cents...

Definitely agree, but 1.6-1.7 60' on stock street tires is VERY optumistic.

60' times in that range on street tires is definitely possible. I've done 1.7s in a bone stock 2002 M3, a modded Supra, and a lightly modded STi (I know... all wheel drive). All these cars weighed more than a Viper, had way less power (except for the Supra), and much skinnier tires. It takes the right conditions, good track prep and some very good driving, but it absolutely can be done.

Well, bone, and I mean bone, stock in my 03 I went 11.93 with only about 2 weeks of ownership. IMHO the GenIII is the easiest car to launch that I've ever owned; compared to my IRS mustangs, my GenII RT/10, etc. Getting 1.8-1.9 60 foot times seemed way less tricky than getting a hard shift into 2nd & 3rd, where the car got squirmy on the runcraps at speed down track - where I get much more nervous about squirminess.
My base dyno was 442rwhp/481rwtq.

I've since added; corsa catback, K&N FIPK, & plugs, and will re-dyno this week and will get to the track again in the next few weeks. If I had a goal for 1/4 times for my car, it would be 11.5 with these mods & installing my SVS short shifter and PS2 tires. I don't know if I can hit that, but it'd be my goal.

I bet the 08's are magazine tested at 11.5 ET, and we see guys hitting 11.2's consistently, with perhaps a 10.9XX here & there. But, I bet there'll be a couple lil tweeks to do & they'll be hitting 10's with very very mild mods. That would be super cool.

It was harder to get 1.8 60fts in my Camaro with Drag radials then my Viper. My first time at track in Viper took about 6 runs of 2.0 -2.2 60 ft's. Then it was pretty consistent 1.8's on the run flats. Im hoping with PS2's theres 1.6-1.7's, we will see.

 

[black mamba1]

I did not know the 08 had an adjustable suspension, I can imagine that will really help seeing as how the Vipers biggest problem is grip. And MikeR, you have me very interested to see what I will run w/ 580 hp and run flats since you ran consistent 11.7's on run craps!
I would not be shocked to see the 08 run like an 11.3 or 11.2 in the mags. The PS2's on my car really make a difference.

Im excited to go back to track too. I love the new PS2's in just a few weeks of street driving. Feel alot more grip at launch, even on the street. So track should be better. Im not a big drag racer but is fun to do once in awhile and then Im going to try and hit road course in May to see how these PS2's do in the turns.

While the new 2008 viper has a lot of cool new engineering going for it I am not in a hurry to run out and buy one as I am getting the same horsepower as Dc claims the new viper will get now. Of course I am not benefiting from the new rear axle or tranny in my 30 viper. the new heads, intake, air box, and clutch would be a nice treat but why spend $98,000 plus tax to buy one when we can upgrade our existing vipers. It would be one thing if the new Gen 4 had a totally new body style but all that has changed is the new hood which we can retrofit.

Right now I am getting the following ** and torque out of my 30 viper.
599.85 EHP & 635.23 ETQ @ 5400 RPMs
509.87 RWHP & 540.00 RWTQ @ 5400 RPMs

As for 1/4 mile times, I have no idea as I believe a Viper is a road racing car and not a drag racing car. JMHO.

Look for 11.2-11.5 in the upcoming mag tests. Motor Trend will post the low number.

RWHP to weight will get it .5-.7 below the '06...and the tires, rearend will be a bonus on top of that.

I for one just really enjoy knowing that our cars are King of the Road in the sports car world. As far as the argument for "why buy a new one when you can simply upgrade an old one" that argument can be used for any year car...hell, might as well get a 93 Viper and slap a TT on it and other mods to bring it to 1000 hp, so why buy a Gen 2, or Gen 3 for that matter? I think we should support DC as much as possible to keep the Viper line strong. I imagine several Gen 3 guys will go for the 08's. I, however, love my 04 and will be keeping it.

I am taking the run flats into consideration. Usually slower then their non run-flat versions.

 

[black mamba1]

The PS2's make a huge difference, also the 08 has better headers I believe. This will make more of a power surge in the sweet part of the curve, hopefully like my current Belangers do. Anybody got any Belangers on their Vipers? If so were you able to monitor the trap time improvements?
