Default 1st gear wheelspin?

Quick question for you greddy guys out there with 200+ whp. Do you guys break your tires lose in 1st? My car doesnt lose traction at all (which is fine with me) but just curious. I have rt-615 azenis in 195's on stock 14" daisies.

Yeah, and I would spin in 2nd if I punched it at 4K RPM at least until last week when I blew it up. I am on 195/50-15 Toyo T1-S. I suspect after I get the 1.8 in and the new setup, I will have to get more rubber out back.

scott I was just referring to off a roll or something not off a launch. My car will not even make the slightest noise of wheelspin very interesting

I would lose traction with 205/15/50 Azenis 615 in 1st and 2nd gear (rarely in 3rd if it was a bit cold out) if I went to WOT while moving (not from a stop) near the sweet spot rpm ~4500.

not sure, if this counts, but i definitely broke my 195/14 RS-2's loose the other day messing with my MBC and going out for a test run. throttle pinned in second gear from 1.5k to see how it pulled, and where the boost ended up.

just before 4k i hit 10psi and the rear tires disconnected from the road... seems consistent with what brg is saying.

My car will definitely unhook 1st gear, even with 225/45s out back. That's on the 8psi setting. At 15psi, 2nd gear depends on pavement surface, air temperature, and whether or not I'm going uphill or not.

first gear is a writeoff. even stock with a clutch dump or not. the torque multiplier is just too great.

with 250 rwhp i break 2nd loose all the time with a roll-on start. the old freeway merge is a killer.

the other day it was cold out and I think I caught some 3rd gear roll-on scratch but I can't be sure.

240+rwhp with the 1.8/3.90 torsen/5 speed/205 T1R's I do not break the tires loose in first unless I delibrately try to.

Older setup, same thing but GT2560R on the 1.6, I did.

It has more to do with how smooth the power delivery is. The 1.6 was very peaky where the 1.8 setup was very linear.

With 14 inch pilots and 8psi, my car spins through first and into second. I love it on the street, hate it at the strip.

2nd Gear on 6 Speed + 4.3 Rear Ratio + 205/50/15 T1R's + 305 whp = NO Wheelspin Whatsover on Roll On...and that was with an open differential.

not a greddy but racing some integra the other night my tires break loose in 1st, 2nd, and 3rd and i never launch hard. if i cruise in 1st or 2nd and mash the peddle around 4000 rpm the tires break loose too. i'm running 215/45/15 t1r's and they never squeel, they just leave stripes. i also run a 3.90 rear with 5 speed trans so my gearing is even taller than stock. 225/50/15's just arrived yesterday so maybe that'll help even with the new twin turbo setup

Yup, first and second are "smoke show" gears when/if called upon. I haven't datalloged anything yet with my 4.10's, but I'm assuming that it just makes the boost hit sooner.

yeah temperature has a lot to do it, first I can never hammer down, second when it's hot out only gets a little squirmy, but in the cold it will spin when the boost hits hard. I still have the stock suspension so i suspect people with stiffer setups might have worse straight line wheel spin.
