how come i cant chirp 2nd?

[kgh31386]

i know my cars fast. but when i drove my friends tc, it almost just didnt wanna stop spinnin the tires. but in mine i get to redline and shift and it wont even give me the smallest...chirp. is it cuz its almost new and the tires only have 1200 miles on them, or is it because i know i dont have a lot of torque?

[Flashmn]

ITs because your car doesnt have power to do it.

[rdyzz]

1. it's power/tq or 2. your car has to much traction. why do you want wheel spin. time spent spining is valuable time that could be spent going forward. in my mr2 it does not spin tire at all even on a 5,500rpm launch. i understand it gives the misconseption of your engine being powerful.

if you do want to chirp 2nd for the heck of it 1. run spare tires up front (who knows you might even be able to chip all gears on the smallest spares). 2.run a supper dry hard compound tire with -3.0 of camber and massive toe out. 3. never invest in a LSD 4.4agze 5.3sgte for sure.

anyways have fun experimenting.

i know an easier way to chirp your tires, put on bald tires

[89yotarollagts]

first off what do you drive.. second go with diff tires you have to much traction/not enough power to spin grippy tires... try putting more air in the tires ! is your car auto or Manual, almost every manual should be able to chirp in second, wheather its a geo, or a ferrari

it's an 06 xrs haha

[rdyzz]

the xrs 2zz really has no tq compared to the larger 2az engine in the scion tc. 2.4 liter (600cc more displacement) will allow more tq on throttle then the xrs 1.8 that has a rod ratio for high revs verus tq. also combine the ge instead of fe head design and thats a recipe for a more narrow powerband. (suposedly using the crank/block off of a 1zz will turn the 2zz into a 2.0L. not sure how true it is but a local is building one in his xrs and has the crank balanced to rev to 10,000rpm)

why does it matter if your car can chirp 2nd or not, your faster right.

[kgh31386]

hmmmm good point

[89yotarollagts]

lol you guys dont understand.. it doesnt matter if your car goes faster when you dontspin the tires... It just sounds/feels cooler when your car spins the tires lol

Short answer, I have soft, floaty winter tires right now and if I punch it, it spins and pulls hard rapidly left and right.

I will try to explain as much as I can. XRS power curve is completely different from Scion TC. Why are you worried about tire spin anyway? You don't like to have your tires run for a long time? A FWD car keeps traction on front wheels through shifts is actually ideal. A well driven XRS is quicker than the TC every time in an all out race stock for stock and especially with N/A mods on both cars. Because it makes more high rpm horsepower/torque across a wider rpm band and is 300 pounds lighter as well.

However, tire spin comes from how the torque comes to the wheels and how chasis is tuned, which is largely dependent on the displacement of the engine and how the nose lifts up during shifts thus reducing the contact patch on the front wheels. TC gets most of it's torque at very low rpms so all of that torque comes in very quickly at low rpms making the car spin it's tires so naturally punching it all of a sudden will cause wheel spin. XRS is also substantially more stiffer (both shocks and springs) so the nose stays low during shifts and with more sticky Michelin tires than the TC so it throws the weight back a lot less than the TC does during shifts thus keeping traction at front wheels.

If you wnat to chirp second try redlining first then punching second and remember what rpm second engages at. My 4afe redline first to second gives me a second gear of just over 3200rpm just below peak power. If I want to chirp second i just bring up the rpms before i punch to second. dont try to hurt anything. I can get my 4afe to chirp at about 3600rpm into second. Not that its good for anything other then sounding coool.

i smell burned clutch

[Beemik]

I dont know how you would smell burned clutch if im only over reving by 400rpm. the engine idles at about 800 and i cant just take my foot of the clutch to start driving i have to keep the revs up to about 1000rpm to get motion in first. i think theres something wrong with your sniffer

[RningOnFumes]

put down some armorall over the tire and gun it lol.

[89yotarollagts]

armorall lol thats expensive !! oil/ coolent works good too..
