VDC off I almost crashed!!
 

I have a quaife diff and a TT setup

The other night, I tried a WOT pull for the first time with VDC off.

In the middle of the 3rd gear pull the car violently and suddenly spun to the right and then to the left before I made it come to a halt. It scared the **** out of me!

Why did that happen? I have Pilot Super sports 275/35 on the rears and I was going in a straight line under WOT, then around the 4000RPM mark it almost felt like someone grabbed my steering wheel and threw it to the right and then to the left!! There was no gradual loss of control sliding etc, it just happend so suddenly out of nowhere.

Anyone else experience this before?

Bro, your car lost traction. The rear was coming around. I will keep the rest of my comments to myself.

Yeah but I didnt know it would throw me around like that, like it happend really quickly. There was no gradual loss or indication at all, it was farked!

Do i need bigger tyres, and or just turn down the boost?

Wider tires help, more rubber helps, better suspension helps, boost DOESN'T help. This is why a lot of people don't care for TT. When it boosts, it BOOSTS and you very well are going to lose traction. Gotta learn how to feather the gas and control it.

Before doing a pull, try heating the tires. That helps too

Well I am removing the EBC this week. It was throwing me upto 14psi from 8 psi even switched off. That is prolly the cause of the huge traction loss.

I just hope it doesnt spin out of control like that again.

I do have alot of suspension mode aswell

You hit full boost and the tires broke loose. That's not a bug, it's a feature. Fix your right foot, not the car.

As he and everyone else said: You have to crawl before you can walk. Throttle control will do you wonders instead of just burying the pedal and hoping for the best. Hope this was a learning experience.

Yep, once in my 1985 trans am NA V8 305, not much HP but i had upgraded gears in the diff, once both wheels loose traction you're so ******. Between gear changes is most dangerous, also small changes in steering will throw power off to one side and if both wheels dont have traction at that moment you're ******, you're much safer with open diff. you need to take the car to the track to practice WOT pulls so you know what the car will do.

you mean running out of talent?

no.. I prefer to drive within my abilities...

fixes for this issue:

a. throttle control
b. more time learning the cars power....gradually.
c. wider tires
d. stickier tires

It's just a and b. A TT Z will blow the tires off at will. Throttle control can quite literally save your life. Hell, didn't some other guy just wad up a boosted Z because he didn't respect the right pedal? These cars are a lot of fun with 500whp, but respect the power AT ALL TIMES or leave the road backwards.

100%

i had mine accidentally kick out a bit with just 325whp and 305 RE-11 last week when there was a bit of water in an uphill turn lol

but 7 years with the car i know it very well and control it.

You may have a suspension and/or traction nanny problem but I suspect that the other posters are correct - you just need more practice. You're trying to control a lot of HP in a light car with a short wheelbase. :driving:

You can and should do mechanical upgrades to your rear suspension but as it has been said over and over you got to learn how control the loud pedal. You also got to pay attention to whether or or not your tires are up to temperature and what type of road surface you are on. Driving a boosted car requires constant situational awareness. Even on the track I have found myself looking In the wrong direction because I thought my tires were up to temp and I got into the throttle and just as you stated...without warning I was looking the other way.

When you learn how to handle the power your vdc will be a hindrance and quite frankly dangerous to you at speed, but for now it is your friend until you get more seat time and experience.

lol honestly that's why i crashed my car. i felt the exact same thing you did except i lost traction completely and it spun out.

im in the process of currently swapping all aftermarket parts + motor to a new Z i bought
