wheel hop
 

Hello All,

I am looking for a good definition of wheel hop? what exactly is it? what causes it? and what is good methods of curing it?

thanks

well, wheel hop i think is when the tires try to spin but end up gripping too much and the suspension starts bouncing up and down. it is very hard on your axles and transmission. as for a cure, i do not know. we were looking for one when my buddy had his Spec V because it was so terrible in that car, but we couldn't find anything.

so its something that occurs usually when accelerating? I'm assuming it only occurs with 5 speeds?

So if I try to interpret your explaination into a cenario, wheel hop would occur say when accelerating and you come off the clutch too early and so more power suddenly is sent to the wheel, and causes a hop?

Wheel hop can happen on automatic cars.

Here are some interesting reads http://tsiart02.tripod.com/WHR.htm

According to this link http://www.100megsfree4.com/dictiona....htm#WhaleTail wheel hop is defined as - A hopping action of the rear (it should be drive wheel or wheels) wheels during heavy acceleration. Traction is lost and regained in rapid cycles after power is applied to the rear wheels. It indicates a need for different tires, better shock absorbers, better springs, better axle control, different driving technique, or all of the above. The British term is "wheel patter"

Big tie wraps on your springs :shiner:

drop your car, it won't happen anymore.

my car is dropped and i get wheel hop, but not as much as i did with stock suspension

So bad motor mount would cause wheel hop? when you shift (5speed people) and that sudden loss in momentum would give a little hop since the motor would swing back some?


thanks for the responces, now that I understand what wheel hop is I know that, I am not experiencing it, but I have heard the term a lot recently and wanted to get clarification of it.

ive read that an engine damper can help with hop.

Not so much when you shift as when you launch. But mine will do it if I'm just rolling in 1st and punch it.

kool, so wheel hop is basically a result of bad motor mounts and/or control arm bushings

and that causes the car to "hop"

Well, bad mounts and whatnot aren't necessarily the cause, but they're the things you want to address if you're trying to eliminate it. The factory mounts are good enough for everyday driving, but aren't good enough for the substantial abuse an enthusiast deals out.

WTF is an engine damper?

Yes, making the motor and tranny mounts harder will limit the movement of the engine, and thus reduce wheel hop. After I put in my PR motor mounts, wheel hop went away pretty much permanently. The only time I can get wheel hop now is by giving it gas in the rain in first gear, and even then it's not that bad. New shocks won't help. You can do the eraser mod to your mounts, or fill them with poly, or find some PR mounts.

It's like a little shock absorber that connects the engine to the engine bay.

sorry to bring this thread back from the dead but when wheel hop occurs does it feel like someone is banging the crap out of the bottom of your car and is really loud? b/c i believe i have this problem and was wondering where it was coming from. i have the symptoms that everyone is talking about in this thread, 1st gear and punching it, in the rain. etc.

what kind of tires are you running/tire pressure?
what is your suspension setup?


there are a bunch of different variables that contribute to this. the easy way to prevent it is to go easy on the throttle in low traction situations

give us some more setup info and we can probably help you more.

i have progress springs with tokico's, falken ziex 912 with about 33psi in all tires. 5 speed of course. i was thinking of looking into some traction bars, do they make them for our cars?

Yes, search.

Available as of September, who knows now.

sorry to get off topic for a second but how do you like the 912's? i was thinking about these for my next tire

exactly. A good example is also when you power shift the car will usually wheel hop a bit.

I get it every now and then at the track in my 240sx when i dont launch it right and spin a little then get to a sticky section of the track and it starts wheel hopping.

I like them alot, b/c their not a directional tire and you can rotate them anyway you want. they look good and do a good job also.

Wheel hop is when you launch too hard at the track on street tires and you bounce up and down so hard your MAF comes disconnected resulting in a 22.71 @ 63 mph

Heh. Worst I've gotten is a ~17 second slip from starting off in second gear (auto).

wheel hop is when you wipers come on.....:mardi:

no more though with the ES motor mounts and ES Snomax control arms

i ran a 14.7@110 lol hopped so bad i stopped and restarted lol
