completely loosing tracktion at shifting

[migsk8]

ok well i was racing this dude the other day right, it was like at a 5 roll.........well i punched it and shifted at 7.5 and when i did my back 2 tires lost complete traction and my car steered left towards some woods, and i was about to smash the curb and go diving in some woods, when i quickly recovered the car. it was a 3 lane road, so i did a pretty good like 3 to 5 feet of "skidding" when i shifted

i just wanted to know, what would be the cause of something like this, how i can reduce it/ eliminate it

first off, i know my tires aren't that good, but they are just 2 months old, they are just some cheap tires but they have like 90% thread on them

also i do realise the SR has about as much torque as it has hp

third off, i have lsd, so when i lost traction i was def screwed in the rear 2 wheels department?( that would be a queston )

ok so i have an SR redtop, with regular mods, so its pretty stock except for intercooler, fuel pump and stuff like that just in case you wanted to know

Sh1tty tires are sh1tty tires whether they have 90% tread or 5% tread left.

I'm going to suggest next time you "race", which I pray is on a track, ou shift sooner than 7500. You were almost 1000 rpms over the power dropoff of a stock setup. You chirped your tires because there was a dimished load strain being put on the tires, and then you shifted back into the meat f your power band, breaking the tires loose.

I have no clue what kind of lsd you have, Different kinds have different effects on rear traction. A clutch type will keep the rear wheels locked together under load, increasing the effects of your tires' inability to hold traction.

A viscous would have had little effect under load when you broke your tire loose. Once one wheel really gets to spinning on a viscous unit, until you can bring the car under control, there's not much you can do to keep that wheel from spinning.

A helical would have the same effect as a viscous in your situation.

Its your tires...no question about it. Not only should you be running better tires on an SR but the width should be at least a 225 if you want some traction. I have some 205/50/16s with -2.4 camber and I have basically the same setup as you andI dont really get traction till 3rd, but thats how its supposed to be for drifting.

yea when i turned up th e boost ion my car, i lost traction betwenn 1st-2nd-3rd it sucked .lol

i raced him again and i shifted at 7 and it chirped and i still beat him

what do you mean by

" You were almost 1000 rpms over the power dropoff of a stock setup"?

Stock cams start to loose wind past 6500. Once you pass 7000, you're wasting effort because you've exited the powerband. When I auto-x I shift anywhere between 6500-7000.
