9.0L Stroker Viper can't stop spinning on Dyno!!

- Had a hell of a time keeping the car from spinning. It would hook up and then break loose as we came on the cam. Made some adjustments at the end of the video (haha).
After we got the tires up to temp and put some weight on it we got 3 back to back pulls in the low 700 range. Highest was 727whp but we threw it out because we could see aberrations on tq (spinning again). I posted the graph from the second in-traction run. Made about 8 pulls total.
As is, uncorrected numbers in this DA (-550ft) were 722whp / 671wtq. STD correction was 701/650, and SAE was 680/630 🐍🏁
Modifications:
Prefix 550ci Billet stroker
Prefix Ported stock heads
Prefix "X" Cam
Belanger Longtubes (catless)
Corsa Extreme 3" catback
DSE heat shielding
IPSCO crank pulley
Drop in filter
Car is stock compression (10.5:1), pump 93 fuel. Cam is a moderate grind for perfect street manners and big AVG power.
I've dynoed the same car, on the same dyno for all 3 setups. Full bolt on (green curve), heads/cam (red curve), 9L stroker (blue curve). I thought it would be great data for the community to have the same car on the same dyno throughout the "big 3" stages.
Power deltas over bolt ons on pump gas are:
+85whp / +47wtq (heads/cam)
+54whp / +89wtq (stroker)
I have included the uncorrected as-is data to show the deltas between setups on the same car, same dyno. I've also included the SAE corrected numbers in case you want to measure penises over the internet with other cars on other dynos. Keep in mind correction factors attempt linear interpolation on non linear relationships and different dynos can be made to read so wildly differently (with a simple drum weight manipulation) that comparing different cars on different dynos is nearly meaningless.
I'm super pleased with the new stroker setup, the curve is absolutely beautiful, it's a torque monster making insane avg power 💪
Kinda hilarious that speeding up the footage actually produces a sound so similar to that eras F1 cars. 😂😍
higher sound wave frequency = higher rpm.
Over 500 lb-ft from 1500 rpm to redline, over 600 lb-ft from 3200ish onward AND over 600 whp from 4500ish rpm?!
Now that’s a proper powerband! Gotta love a big-inch, properly tuned naturally aspirated motor! 💪🚀🏎
OH MY GOD THE SOUND
Making damn-near 550 rwtq at 1,650 RPM 😮 Holy shit-balls. She rowdy 🤤🤘🏻🇺🇸
Been too long between uploads!😭 my dream car.. Love your Viper!
Bro ТЫ crazy :))) love the car man.
Got to get A Viper to cure those F1Dreams...😎
What a classic design
One of the best cars ever made.
Please tell me I'm not the only one that wants to hear a built viper with ITB set up?!! Would sound amazing.
You're not the only one. Check fluid motor union for sick ITBs videos
This thing had so much torque you might as well idle your way through 6th gear and still be effortlessly faster than most cars around you in the freeway while idling.
My FBO/Cam 4.6 Mustang made ~360 wheel NA. It's neat that at basically double the displacement w/ similar mods your car makes double the power.
What's your fuel system setup? (BAP, dual pumps, return-style?)
Stock everything, just an upgraded walbro fuel pump
What are the cam specs on your build!!? Sounds amazing, love that it kept the drivability too
9 liters and it only made 722hp at best?
More power babe
I guess you didn't have the SAE curves for all 3 either way that is amazing. We know the car is faster because well it is. All the torque right where you need it as well.
Everything is posted at end of video, guess you didn't make it there..
My attention span fails me. Anyway I was talking with Zack barnes and Andre about you coming to an autocross. They say you won't do it but I'm holding onto hope.
Most operators know this but if you pull the car ahead more on the Dino it doesn't try to climb over the roller and spin the tire
Badass!
💙🐍🔥
Curious on what the drop in filter looks like and how it performs vs an open filter design
FINALLY!
How much more power can you squeeze out with e85/race gas?
DAMN
i love dodge viper :0
Woowee she is a bad B
wish my vip sounded sweet
Damn I want it so bad
E85?
93
Not gonna lie, for that insane displacement 700 wheel sounds pretty dang inefficient to me when a 2 liter does that with a a little boost or a v8 does that on pump with a cam and bolt ons.
😆 Please link us to a 2L that makes 670wtq with "a little boost". Also link us to a V8 that makes 720whp on pump gas, stock compression with a cam.
We'll wait 🤣
Whats the mileage on this beast if u use it so often
Currently around 26k
@@SneakySnakes not that much! Take a good care of him. Deserves it ! 😎
Not sure why you are spinning on the dyno, my Hellcat made more power and torque down lower than your car did on a 275 pirelli and did not spin?
More weight over the rear tires would explain why your Hellcat did not spin . The Viper weighs a lot less and on a dyno you don't get the weight transfer when accelerating on the street.
The weight of the car is part of the issue as well as the dyno itself. Some dyno's when they are fairly new can have issue's with bigger power cars spinning because the paint/powder coat creates that issue. Some independent rear suspension cars can also have this issue based on how much negative camber is being used causing less of the tire to actually touch the ground/rollers. The suspension on the Hellcat's is honestly impressive. If you tried to put 600+RWHP to the ground in a 2010-2015 Camaro on a 275 tire it would only be possible with a worked over suspension and a drag prepped setup. The Hellcat does well on the stock tires and is about perfect with nothing more than a drag radial.
Hi
Its amazing it makes so much power. I wonder how much longer before the price on the viper drops to where a lot more people will do heads cam on these. Anyone make a better intake to pick up any additional power
Bad news...they've doubled in price since your comment lol
This beast is so freakin badass...
V10 😍 💪👊
I was hoping for a comparison graph! That 9.0 REALLY fattens up the midrange.
Very nice. It's cool to see someone play with a Viper without going instantly to turbo's. That is a very strong power band. That would be fun roll racing where you and the car next to you lock in 4th gear at say 2,000 rpm and roll on from there.
one thing very noticeable is how much more torque you have on the low end. Was expecting more whp, but that torque number appears much much higher than stock at low-mid rpms, like twice as high.
Well done impressive & NA! Surprised with that power level you couldn’t pull the 720S those cars seem to be the car to beat these days but honestly I would take your Viper all day.
720s makes the exact same power, with better aerodynamics, better gearing, a dual clutch, and 300lbs less weight. No surprises there, hanging with one in this archaic steel chassis dodge is an accomplishment
@@SneakySnakes Wow didn’t realize they make that much power at the wheels stock. Bottom line good work great build and enjoy it!
@@Justin-zg1ws stock 720S don't make 722whp , most of them are in 660-680whp range
@@derekk5992 722 was uncorrected in negative DA. My SAE and STD numbers are between 680-700. Ive seen 720 make up to 715whp, so yeah we make about the same power.
I wouldn't mind more f1 v10 noises lol.
Where the hell have you been. Oh yeah...sneaky snake. Love this car, best N/A car evee
SS this has got to be the best sounding Viper on the planet. 😎 👂
910 Nm of torque that’s nice.
*Nasty* ! 😈
This car on race gas would be ludicrous
Hi love all of your videos I remember when you had a gen 4
Was wondering if you had a recommendation of parts to get for a similar na build to yours for my gen 4 any help would be greatly appreciated
When not just mirror the simple setup I had in my gen 4?
All of the modifications are listed in those videos.
I saw your list of upgrades do you have a recommendation for a head and cam package also?
@@kennarddurant In my opinion Prefix, nth moto, and AC performance would be the shops I'd look into depending on your region. I'd ask owners of said packages past the honeymoon phase to give you their experience.
Curious to know what you have planned next for the snake?
Suspension and brakes
@@SneakySnakes Any plans for straight cut gears?
@@SneakySnakes Wow I want to see that!
