Last night of Test and Tune at Atlanta Dragway tonight.....sure to be overcrowded.
I don't have much confidence in the car getting traction on the stock tires.....but I want to try it anyway.
If it doesn't run good at least it looks DAMN GOOD! LOLOLOL....and I will leave it on the trailer and...
I agree with Nine, the car is a manikin to showcase the products that the company is offering. Hard to beat the factory wheels though....some things are better left untouched.
Not calling BS yet on the IAT issue, but that really sounds iffy. Most months of the year Las Vegas sees daytime high temps well above 100 Degrees F so driving through the hot air will not reduce IAT's therefore resulting in continuous power reduction. Could be the same for folks residing...
Nine Ball,
Thanks for the update. I would love to talk to these guys, especially regarding the pulling of HP and Torque on the Dyno.
The day I ran the dyno the IAT never exceeded 90 Degrees and the OAT was about 75 Degrees and plenty of cool down time.
Did you ask about the...
Nine Ball,
Thanks for the very informative post! Hopefully weather permitting and I can get back home from Asia before Friday, I will take my 2013 to the track. After reading your post, I think I will pull all of the ECU plugs and replug after each run, just for the hell of it. There are (5)...
I'm in Manila now, heading to Hong Kong but will be back in about a week. I did try pulling those plugs but did not
work. I don't know if there is a sequence or if they pulled them and plugged them back up after each pull.....I have
tried to reach out to the engineers, but they have not...
Hi George,
Based only upon my trial and error, i think that the ABS/ECS/Stability control issue is defaulted to a higher speed as just running the car momentarily on the dyno to check for truing and strap adjustment in 1st or 2nd gear isnt enough to trigger a fault in one of those systems...
Rocket....
I think other tuners ARE having the same problems on the dyno...they are just not coming forward with it. My BONE STOCK Viper does the same wacky dyno curve even without nitrous.....but ONLY after the first pull because after the first pull all the ECS/ABS idiot lights come on.
I...
Hi Jack,
I don't mean to come up against you on something as you are way ahead of the curve...but i dont think that the Nitto tire Nine Ball mentions is any larger in rollout then the factory tire. I actually have a pair of those coming myself as my stock rear tires are useless now with all...
I have a short video of one of the nitrous pulls from yesterday....but will have to send to someone to post for me.
Will take more tomorrow if all goes well.
Jack,
Yes, I turned it all the way off (held 5 seconds) before the first pull and then could not do anything with it after that.
Yes, the wide band was after the cats. That is the problem. At @ 5000 RPM something is taking charge in the computer and probably pulling timing and adding fuel...
Thank you very much, Tony.
If we look at the middle sheet it is a comparison of the very first pull of the session and a subsequent pull. On the first pull (RED COLOR) the computer has NOT sensed any abnormalities and the graph looks clean and linear (in this case the 539 RWHP pull), but after...
Tony,
Thanks, I emailed them to you.
ACR...Thanks for your reply. Your post was ambiguous which led to my reply, which of course was not...LOL....I apologize.
Has anyone dynoed a Gen V Viper that wishes to share their pulls? Did anyone have this same experience whereas the first pull was...
Enthusiast? Check my join date......
I have been a member and supporter and Dodge Viper owner since before this website was in existence. Useless banter and heckling is why I refrain from posting here, but after thousands of dollars and countless hours of my personal time invested in trying...
Hello All,
Got to the dyno this morning (maybe raining by Friday) and made a few pulls with the nitrous system on my 2013 GTS. First let me say that the car LOVES IT! I was satisfied with the Wheel Torque of 771 Ft/Lbs which equates to 887 Engine Torque.
The horsepower is not coming up to...
LOL....still got that old 97 GTS. Can't bring myself to part with it. Lots of Viper Drags wins with that car. An interesting note, my brother and I took the two Vipers out on the airport runway (keep all the cars in my hangar) and made a few first gear rolling start passes and they ran as...
Finished the Nitrous Injection Install on my 2013 GTS tonight. Designed a simple setup that doesn't depend on or pass through or utilize any of the onboard ECU facilities. Hopefully this will eliminate interference with SOME of the engine management software built into the ECU. Out on the...
I'm currently tinkering with a Nitrous setup for my Gen V. Will let you guys know how it goes. The good thing about a balanced Nitrous Kit
is that you eliminate any need for ECU tuning. My only concern on these new "smart cars" is getting the nitrous through the maze of sniffers
and OEM...
Yes,
Once it was running in neutral I held the ECS button 7 seconds to turn off ALL nannies....and the first
pull was a smooth graph and a "warm up"
When i started the engine for the second pull i noticed the Stability control failure in the center display
and then could not turn off the ECS...
Earlier today
Dynojet 248
What is interesting is that on the 2nd and 3rd pull I was unable to deactivate the ECS as the
system had triggered a fault for "stability control". I had seen this before with my ZL-1 Camaro.
With the Viper though, it is clear in the 2nd and 3rd pulls that the ECU...
Just did this tonight. Car has 450 miles. Wondering if it's bogus. Was playing with the launch
control and on this particular run it didn't engage (my error) and i dumped the clutch at almost the
limiter. Was on concrete 4 lane highway but still glazing the tires and bogged after shifting...
