First Gen 5 Viper in the 10s!

The external run shows a smigeon of bog. Looks like there is a little left if that could be eliminated. Do you think it would take a first gear change?

3.73 rear gear would be perfect for a stock Gen 5 at the drag strip. That would make the effective 1st gear more aggressive than the 2008-10 trans, and would put the car into the sweet spot of the rpm band at the top of 4th gear, near the finish line. Should be possible to go 131-132 in 4th with the 3.73. That would be perfect.

Im with nineball on this one. Jamie Furman in that 08 viper that ran a 10.92 @ 129 mph was at the worlds fastest drag strip in a negative 1500 density altitude if memory serves.

Put this genV in the same conditions and she will land somewhere between 131-133 mph.

Nine Ball · Dec 17, 2013

I'd like to remind people that I was only the first to do it. I don't claim to be the best driver, as I fully expect others to beat my time. I also would not like anyone to start bench racing about how all 5th gens run 10s now, just because 1 car did it. There is still a driver factor involved, after all. To date, Furman's gen 4 has been the only one to run 10s without mods. That is a combination of weather and driver skill. Results with other users may vary... a lot

DA was -915, not that much of a difference.

Def has all to do with the driver!!! And I know of at least one other GEN 4 in the 10s with no mods. Regardless like I said you have the bricks stacked against you with this car and the lack of performance SRT handed you. So hats off to you Tony!!

Date is mentioned on Furman's video, 3/23/09. Judging by the shadows of his car on the ground, I'd guess mid-day. Works out to -1500 ft DA, according to historical measurements. Here is a direct link.

Temps were in the low 40s that day, very high barometer, and very low humidity. That is about perfect for setting records. I used to competitively bracket race, I kept a log of DA on my runs and monitored changes due to weather, so that I'd be able to dial my car in accurately.

Can you measure the tire diameter, the specs are typically a little skewed.

That pass was at 3:02 pm

FLL-B/W-GTS · Dec 17, 2013

Agreed,the Gen.5 is not a 10 second car as it is.I knew a very determined individual may tweak a 10 second pass with drag radials if everything is just perfect.I dought you will see a 10 second pass as a complete factory car.None the less, outstanding job you did getting the Gen.5 to do at least one pass in the 10s..

One thing that this does show,is the Gen.5 is one tough machine,Really 27 passes without breaking(Crazy)..Impressed....

For the record, there's this pass too:

To be fair though, there seem to have been some small mods on this car. Not 100% stock but very close.

This car was said to be stock as well. No mods.

Site still shows it at -1054 DA during that time. Still better conditions than my -450. That extra -600 ft is easily worth another tenth and 1 mph. Furman is also a proven driver, I just have a lot of seat time.

Malu (Jason) posts here. He had the mufflers removed from that car. Not sure if he kept it 2.5 or 3.0 exhaust pipes. Not worth much, most likely, but that does count as a mod since a catback would also be a mod. That being said, you don't see a lot of Gen 4's out running 10s, either. It is a LOT harder to shift a manual car into the 10s than most people think. Getting there with only 127 mph like I did, took a lot of practice.

Yes his video stated that and says he LOST 7 RWHP.

Ill second your motion on shifting to a ten second pass as I have a good solid handful of 10 sec passes on Vipers and corvettes. So I finally opted to have a more consistent drag racer and do an automatic tranny conversion.

It will be nice if we can ever have the ability to calibrate the ECU in these cars so more people can enjoy 10 sec passes as well have the ability to modify the car and give it the power it should have come with.

Congrats!!! and well done as always. I like the way you always give as much detail about mods and your runs.

Jack B · Dec 17, 2013

Very nice, it is amazing some of the accolades in this thread give you a slightly warm "OK", then quickly slam the car. If you ran a 9.99 someone would find something wrong. I am sure glad all the G2, G3 and G4's were turning 10's six months after they were introduced.

Par for the course, on the good 'ol VCA. I hope I've reduced some of the Gen 5 hate, with my results.

The fact is that this is the first time we owners have gotten to race in cool weather, since most of us didn't get cars until May or later. It has been 4 yrs since Furman ran the 10s in his Gen 4, and nobody has beaten it yet. That says a lot about his driving and the stellar weather that day. It isn't easy to do.

I think its ABSOLUTELY AWESOME he got this car to run 10s and its one hell of an achievement on his part, for taking a car that has continued to show lack luster dyno numbers and 1/4 miles ETs . And it should have been easier for others to acheive this "on paper". Being the car has 40 more HP and weighs around 100 lbs less than a GEN 3. Nothing about the GEN 4 adds up to me as far a straight line performance goes.

You have just increased the love for your driving skills!!! LOL

Twister · Dec 17, 2013

We all have our opinions. Here's mine.

Some genV are gonna dyno 540 rwhp. Most are gonna dyno 555 rwhp and some are gonna dyno 570.

Sometimes you just get lucky and get a beaste.

I don't belieave this is a beastly genV that just ran a ten second pass.

Hope Im not being offensive.

Nine Ball · Dec 17, 2013

No offence taken, Twister. I've yet to dyno this car, because I prefer to race instead of dyno. I can be coaxed into doing a dyno though, I have some time off the next few weeks.

Personally I would go with the 2008-2009 transmission instead of the gear change for a better launch and all around daily use. I like the overdrive 6th gear in the 2008-2009 for highway cruising with less rpms. Others may opt for the 2010 transmission which improves first gear over the 2013-14 while keeping the 5 and 6 gear improvement for top end that the 2008-2009 doesn't have.

I just removed the mufflers to make the car louder Tony, kept the same diameter piping. My best dyno stock was 560whp at a dyno day a month after I bought the car, my best dyno without mufflers was 553whp at the Viper Roundup dyno day at ART about 3 years later. The day after my 10 sec run, it made ~535whp at another local dyno day. We know the dyno is just a tuning tool, so not sure if those numbers really prove anything.

You and I know what it's like to run 10's, and it's not a simple task, but it sure is fun to prove a point. Congrats again!

Nine Ball · Dec 17, 2013

Good info Jason. I would like to see you in a Gen 5 before it gets hot outside again, so that you can go bust your old record.

Jack, I measured the Nitto drag radial for you. It sits at 26-7/8" tall, off the vehicle. It is a 345/30-19 Nitto NT05-R.

That post will probably go down in history as earth shattering! When the earth crumbles it will still be remembered.

It sounds like there's a case to be made for a 7 speed to cover all uses while keeping ratios close enough.

Nine Ball · Dec 18, 2013

I like your idea, Bruce. Keep the current ratios, but introduce a 3.73 rear axle ratio. Then add 7th gear with a 0.50 or taller OD. I'm used to having to use 6th gear for max speed, my '06 with the revised 5/6 gears goes to mid-6th in the standing mile. Feels kinda weird grabbing 6th at WOT though, no lie. Ha

First Gen 5 Viper in the 10s!
