How do u cure Wheel hop?

x_fg2_x · 06-29-2009, 04:07 PM

Ok so I went to the Streets of Willow this past thursday with AE Performance. And I was getting some real Nasty Wheel hop all over the track. For those that know the track, I was MOSTLY getting the wheel hop in the bowl, as well as the last turn in the skid pad area.

Now, to be honest, I cant say that this is wheel hop cuz quite frankly, I have never seen a deffinition of wheel hop. But I have heard some people talk about it, and this seems like it. So to describe what im feeling/hearing. This "wheel hop" occures when I am in Mid turn, and im full thottle on the gas. I feel as though the engine wants to push more, but the force of the car turning is preventing it from going anymore. So in result, while im turning, I feel and hear the engine rev'ing up a little, and then going down, then back up, and down. But it happens fast. Imagine the tach bouncing off the rev limiter. Kinda like that. But im only at about 5-6k RPM's . And its bouncing like that.

This affects then car because while im turning, the force of the engine "hopping" is causing the car to get unstable from it slightly accelerating and slightly decelerating and a constant rate.

So my question is, why is this happening, and what do I need to do to fix this?

----------------------

Here is my settup:

Engine:
apex N1 catback
T1r test pipe
custom ram air intake w/ K&N air filter

Suspension/wheels/brakes:
skunk2 Pro-c's 12k front , 10k rear
dampers set to full stiff in the rear, 5 clicks from stiffest in the front
progress 22mm rear sway bar
alignment (camber) = -2.5 front ... -2.3 rear
Volk TE37's 17x7.5
Nitto NT01 225/45 R17
air pressures = 35 front, 30 rear (all cold)
porterfield R4 front pads, R4s rear pads
stainless lines
ATE super blue racing fluid

I gutted the interior, no rear seats, no front passenger seat, no interior trim panels from the b-pillars and back, no spare tire or trunk liner.

I also have an APR front wind splitter

I have skunk2 14k rear springs in my garage, waiting to be installed if that is what needs to be done.

Its that easy of a fix?

jesus that wheel hop was rediculous

Asif22 · 06-29-2009, 04:16 PM

I would say try to epoxy your motor mounts or get aftermarket ones from say innovative

1slo4doe · 06-29-2009, 04:17 PM

i have an ETD and it works very well. if you have the money and the time though nothing beats mounts in this situation though.

jdm free · 06-29-2009, 04:36 PM

start with a tq dampener first. if that dont hell alot at the stiffest setting go for motor mounts.

I dont believe what you are experiencing is wheelhop. When you wheelhop it sounds like a large Scandinavian viking is pounding the hammer of thor on your firewall.

Sounds ot me like youre just losing traction

akronmusician413 · 06-29-2009, 05:07 PM

^yaaaaa...thats what i thought

superbike81 · 06-29-2009, 05:11 PM

Yeah, it's not wheelhop. So what the people above suggested won't fix your problem. Do you have traction control? Is it on? I can't think of anything else that would make the engine sound like it's at the limiter at 6k.

SlightInterest · 06-29-2009, 05:11 PM

I thought wheel hop was when you're trying to take off frrom a stop and the tires bounce...

superbike81 · 06-29-2009, 05:11 PM

It is.

wheel hop normally occurs when launching, not mid turn

Edit: superbike beat me to it

akronmusician413 · 06-29-2009, 05:13 PM

maybe the OP is experiencing something with the LSD...(i dont have an si and i dont know how that thing works but it might be the problem)

SlightInterest · 06-29-2009, 05:15 PM

My friend said it was because my suspension was getting bad, on 10,000 miles. Is he smoking crack?

1slo4doe · 06-29-2009, 05:50 PM

10k miles and he thinks your suspension is getting bad? are you jumping it or something? lol
