Wheel hop ????

[Mopar-man]

I have a 2006 viper srt, the problem I had yesterday I took the car out & when I got on it from a roll it was fine till I hit about 4500 rpm then everything got violent ( everything shaking violently) the car is very low milage, never abused. Could it be the original runflat tires?

Yes of course and the payment is still not that warm. Plus were tires warmed up?

Your very lucky you didn't find yourself in a ditch or into someone else!!! Please change your tires. The same thing happen to me a couple of years ago. Getting new tires
is alot cheaper than replacing a car or paying a hospital bill.

+1
An absolute requirement.

Sorry, but I never heard of tires causing a vibration only above 4500 rpms. Was the shaking RPM related or vehicle speed related? If the former I would think the engine or trans is the issue. If the later I would think rear wheel bearings or half shafts. Did the shaking stop if you put the clutch in? Did it shake in any gear when the engine hit 4500 rpms? If it did I would say engine or input to trans.

It only did it under hard acceleration in first gear, it was ok in higher gears

He is getting normal wheel hop, I get wheel hop on PS2 tires when its cold out in first gear too. Its just a lot of power with little traction thats all.

Sounds like wheel hop - How long before the good ol' run craps warm up?

Stay safe!!

It all really depends on the weather honestly....

While tires have alot to do with wheel hop. Slap on a new set of tires and a set of motons and say bye bye to wheel hop. My 08 with good PS2's would still wheel hop even when warmed up until I installed Motons. Absolutely no more wheel hop!!

Cold tires+cold road surface+heavy right foot = wheel hop almost every time. Continue this and you'll be buying a new rear diff. -don't ask how I know. When these cars wheel hop, it's like hitting the spider gears with a jack hammer!

Wheel hop is mainly a product of IRS and suspension. Tire type & condition amplify this. The Sport Cups are real bad until they warm up. This is the reason many drag only terminator Mustangs convert to solid rear axles or install 2x4 blocks in the suspension effectively prohibiting any travel. Stiffer suspension settings (Motons, K&W, Penske, etc) on the shocks will help reduce this.

Allan is very correct about strain on the drive train, the stickier the surface and the colder your tires the harder the hop. Look at ART's video's on the Tube of their last TX Mile run where the boost cut hit 3 times breaking 5th.

Regarding heat up time on run flats - they take forever to warm up (2 hard laps on the track). Then when they do they retain so much heat and never cool down and become very greasy (after 5-7 laps they are over heated). They will take 30 minutes or more of sitting in the paddock to "cool down".

Normal!!!!!!!!!!

I've changed my tires.....still wheel hop
I've changed wheels and tires ....still wheel hop
I've changed my trans mount...still wheel hop
I've changed my suspension (kw's).....still wheel hop


Sum it up,,,,,I still have wheel hop! Maybe not as bad but it will all depend on temps, pavement conditions, etc like others have mentioned. It's the car!
