What would cause a Starquest to get sideways when accelerating?

[AustinTSI]

So I've been told that when a Starquest starts getting a lot of power it will start having problems staying straight when accelerating even from 40mph.

 

Specifically, it was mentioned that in 2nd gear with an HX40 turbo that if you floor it then the car will get sideways.

 

I haven't had this problem myself since I am still working on my build but I have heard of it in the past about other cars.

 

So my questions are:

1. Does this happen to the Starquest ?
   
2. What causes this ?
   
3. What can be done to stop this ?
   

Thankx.

you get good tires.

its called power and lsd =) its really bad in the rainlol Edited December 28, 2011 by jayro

... really??

 

It's because the car has an LSD which means limited slip differential, causing both rear wheels to spin at the same speed under certain torque conditions.

Someone that drove a RWD LSD in the rain one time and was stupid came to that conclusion.

...and was stupid? i disagree completely. i quite enjoy it.

Being implimented by government for safety in new cars.

 

It is one step closer to having vehicle pilot themselves.

 

 

http://en.wikipedia....ability_control

Electronic stability control (ESC) is a computerized technology that may potentially improve the safety of a vehicle's stability by detecting and minimizing skids.

When ESC detects loss of steering control, it automatically applies the brakes to help "steer" the vehicle where the driver intends to go. Braking is automatically applied to wheels individually, such as the outer front wheel to counter oversteer or the inner rear wheel to counter understeer.

Some ESC systems also reduce engine power until control is regained.

ESC does not improve a vehicle's cornering performance; instead, it helps to minimize the loss of control.

According to Insurance Institute for Highway Safety and the U.S. National Highway Traffic Safety Administration, one-third of fatal accidents could have been prevented by the technology.

 

So in order to have similiar control , (in a non ESC equipped car) the driver would let off the accelerator pedal

and apply the brakes (lightly) while correcting the steering (direction) without over compensation (panic)

In addition,

a vehicle with a manual transmission the driver could shift into a lower gear,

only if applicable to the speed of the vehicle as not too rapid a RPM descent,

or another method would to engage the clutch while braking

and correcting the steering and tapping the accelorator to increase drive train RPMs (slightly) then (gently) releasing the clutch,

while still maintaining controlling of braking and steering .

Also,

Anything tou can do to improve throttle response will help you to control your vehicle,

not just increasing injector drive time but decreasing it as well,

(this helps with engine braking).

 

In most normal driving situations ESC will work, but on a road course most experienced drivers would want complete control since it adverse conditions the ESC computer will shut down the engine,

computing it is disabled.

 

Testing on a Dyno.

If you have an ESC equipped vehicle with only two drive wheels

you would need to disable it or use a 4W dyno.

Tuning on a Dyno,

it has been reported a ESC equipped vehicle will lean out more than a non ESC vehicle.

I know the year is almost over but....I'm gonna go with worst question of 2011.

agreed!

i love th rain and second gear!

[R-R-Quest]

I'm confused. What's the problem? I thought that was the whole point of increacing horsepower.

[Skullzaflare]

my car doesnt do it, my car doesnt move

sounds like the flux transducer is failing, im willing to downgrade and trade for your car

[slydogg]

if it does ever happen, try the steering wheel. i love it when it happens.

[Soopaquest87]

i love when it happens my car aint even running right and can get sideways.......thats how you scare v8 and honduhs get a quest sideways lol

[QuestFan]

He's from Austin TX. they are all wierd down there. I can say that cause my dad lives in Austin. lol

 

But really??? Getting sideways in a SQ is like crack for any car owner.

[Chad]

In essense, the rear is pushing on a load that is almost entirely infront of it. When the force becomes great enough to beak traction, it's nolonger able to track straight behind the front so it will apply that forward force at any angle that aleviates the resistance. It will find less resistance for forward motion if the front "load" moves to the side and out of it's way. Thus the rear tries to pass the front and the car slides sideways in the rear.

 

It's like comparing 2 shoping carts where the rear wheels are fixed on one, and swivel on all 4 on the other. On the one where they all swivel, it's actualy difficult to push it in a straight line. You push from the rear just like our car does, and that force want's to pass the load by pushing it aside.

 

the only fix is to get better traction, or to convert to fronw wheel drive where you no pull the load instead of phusing it.

[19cturbo]

the problem is, you need to convert your car to MPI, that will fix the problem, because as of right now, mine is a fully converted MPI car with a holset HX35, and it wont pull a greasy string out of a cats butt!

[Laodicea]

I have an HX40 and mine doesn't pull sideways.

[Caliber308]

Funny???? My car goes sideways for only a split second.....Then the Limited Slip Differential (LSD) kicks in,even in the rain it straightens out

I'm surprised to all the posts on this All of the tech info was great & informative as well. But as for me: Even a stock StarQuest w/ excellent tires is capable of "get'n a lil sideways." It's an AD Rush! As for in the rain... WHOA! That can be "on the edge?"

[Caliber308]

WHOA! That can be "on the edge?"

 

Good tires make a world of difference.

What I wanna know is why does the tail end always kick out towards the passenger side when going straight ?

[markhansenconquest]

its called driftinggggggggggggggggg

More weight in the Differential on the drivers side. That, and the fact that your a-- is on the drivers side of the car

 

 

Just Kidding Scooter,

Having drove several different ones the LSD doesnt always act the same from each one to the other. And I love that gives the cars more of their own character!
