Bolt on Gen V Viper vs. ByDesign Stage IV Porsche 991.1 Turbo S

[Sticky]

This is a hell of a run by the Viper. The car only has bolt on modifications. We're talking Belanger headers, an intake, cat delete, and an ecu flash tune through HP Tuners. That level of modification on the 8.4 liter V10 will result in roughly 600 to the wheels on pump gas.

The 911 Turbo S not only has the advantage of a PDK transmission compared to the manual in the Viper it also has upgraded turbochargers. Readers here should be familiar with the ByDesign Stage IV package as member @Markblackwell has it and has run 9.7 @ 143 in the 1/4 mile with it.

This Viper won't trap 143 and ByDesign Stage IV packages are not all created equal as there are other mods one can do. Also, race gas is a huge factor. The 991 Turbo S here is running pump gas. That means it isn't making the 747 to the wheels one can hit on race gas.

Still, incredible showing by the naturally aspirated Viper with just basic mods.

That race meant nothing to that Porsche driver.

Porsche is weak. Stock turbos can do 9.9 in the 1/4mi lol, I saw the slip proving it.

Why do you say that?

[Markblackwell]

My car when it was a Giac stage 2 tune would be neck and neck with a new full bolt on viper from a roll from a dig it would beat them bad

my bydesign stage 4 absolutely slaughters FBO vipers from a roll and any speed

The look on this face and his one handed racing style.

Even on pump gas?

[Markblackwell]

there is a gas station within 2 miles of my house that has vp101 so 90 % of the time that's what I run I only have 91 in it on long trips. So I never really race it with pump. I think it made around 630 to the wheels on pump.

From a stop obviously you'll win. From a roll though a bolt on Viper is tough for a tune only 911 Turbo.

Here is a race when I was tune only with 200cel cats

[Markblackwell]

this was a 40mph roll I had a passenger, tune only with 200 cell cats
FBO viper with nitrous he did not use the bottle. My kid didn't have the camara on the viper at the end but he was creeping up and got me by a fender. I let off at the cones and he keep his foot in it a little longer it was a great race

I think you're linking to local images and that is causing the issue. Try uploading the image you're attempting to reference.

Mark: What's your 60-130mph time now ?

[Markblackwell]

I ran a 5.33. 60-130 I've only tried in July when I first got my stage 4 . In a couple weeks all have my car back together with the upgraded PDK
and I'll go run some 1/4 mile and 60-130 times when it's cool and il have some new records to post

[turbo_ssdd]

Damn, really fast already... Can't wait to see !

You'll definitely have some new records to post. That upgrade is taking a while...

[Markblackwell]

I got the PDK back on October 6th put 70 miles on it then ran the Mojave magnum on the 8th and long story short we had problems with high oil level and Positive crank case ventilation and the car blew oil through the entire system and went into limp mode and shut down at 205mph which was 210 on the speedo on my first and only run at a DA of 4,050. The speedo was moving incredible fast until is wasn't. So we missed shift sector which we are hoping for 180 in the half mile. I am also signed up for the Red list Dec 3rd, which I dont think we are going to make, With any luck we will have the car back on the Road in 2 weeks and shooting for sub 9.50's at 146ish conservative estimate.
