Burnouts: couple questions

[Johncrow]

How bad is it for your car?

Should a stock lt1 equiped caprice be able to spin tires just flooring it on dry pavement?(without breaks applied)

How fast can you guys get your stock caprices (at a standstill) to go in a burnout on the speedo? I get about 11km/h nowadays (about 6mph) and is that allright or should i be able to get it higher?



by the way 94 lt1 open dif

I have an 88 with a carbureted 350/5.7 that has numbers close to an LT1 and 3.08 gears with an open diff, and it's just a simple matter of giving the car a little more juice than it needs to get started, in order to get it to burn out. It's funny, but this is the first car I've owned that can do any sort of dry pavement burn and it does it with little prompting. I've never paid attention to the speedo so I can't tell you that (I make it a policy to avoid burnouts whenever possible, not always easy to do on the hot summer Arizona pavement), but I will tell you the wheels stop spinning when the transmission shifts into 3rd. I have hit over 3,000 RPM during a burnout, however. 3,000 RPM is something like 30-35MPH in first, 45-50 in second.

Now, burnouts can lead to broken U-joints, bent axles, twisted axles, twisted driveshafts, and transmission death. That sort of thing. It can also lead to a huge fine and possible jail if you get a cop in a bad mood (if you're on public streets when you do it).

Its kinda funny, but cool at the same time to see these cars doing burnouts or drifting cause they werent designed for it, unlike a camaro iroc-z, trans am, corvette or something like that (those are fun cars to burnout in!). I've done brakestands a few times on mine but i hate doing it too much cause if i screw something up i sure dont have the $$ to fix it right now, my weak little 305 cant really do much stuff like that anyway.

I would think so... my 305 used to be able to do it effortlessly... only one wheel though. It really shows though if you d it a lot. The tranyn will start to go and engine will slowly lose power form being beat on all the time. There were some real nut kids I used to go to school with the really beat the crap out of thier cars. It was like 10 years, 100,000 miles of drivetrain wear in only one year, 10,000 miles.

heres a video i made a few months back of a good brakestand burnout before paint and the flowmasters of my car: http://youtube.com/watch?v=CzIIw1lbXiI

yep. my 305 is a one wheel peal as they call it. i'm sort of glad this car doesn't allow for much fun in that sense. i'd hate to be going through hundereds of $$ in tires and transmission parts. plus my car is in such pristine condition it pains me to do such a thing.

With a properly/maintenance'd running LT1, you may or may not be able to spin the tires.

Depends on tires, surface, if the car is cold/warm, etc.

I wouldnt feel to bad about not being able too

[silicon212]

It mostly depends on how wide your tires are, how 'sticky' the compound is, the condition of your shocks, how 'slippery' the surface is and how much weight is in the trunk (more appropriately, how much is on the rear axle).

I used to be able to do the 'one-wheel peel' in a 1974 Vega with a TH250 and an engine that couldn't push the car over a 6% grade. A little water goes a long way!

well wet parking lots are my friend for burnouts.
once in highschool, i remember doing a burnout on freshly "re-finished" parking lot on a rainy day.

you know the stuff.
they basically paint the old asphalt to make it look new.
well i found out that it gets REALLY slippery in the rain, and did 3 complete spins once.
the first one was unintentional. i was leaving an after school event, and nobody was around, so i gunned it and it broke loose.
i gave it some opposite lock, but halfway through correcting the oversteer, i decided to ride out the spin.
after the first spin, i was having too much fun and kept it going until i dried up the pavement or warmed up the tires or something, but it stopped spinning after about 3 spins.

that was fun.



another time, the same parking lot flooded in winter and froze over.
there was about 1" of ice covering the ENTIRE parking lot.
yeah.
no explanations necessary.

this is a nice caprice. i think its a 94 with LT1

[mike561]

i hate though when im at a red light and its wet out, if i step on the gas a little too hard ill hear the back wheels spinning

[PeteA216]

Ah yeah I hate that... that one wheel peel thing for yah. There was the one intersection where I live, down in the village. Always tough to get out because of the traffic. In the rain... forget about it. I tried a few time only to have the wheel spin and the car creep forward. I had ta stop and back up real quick and wait for another chance. Of course at the time I was riding on burnout-made drag slicks. But even with good tires, these cars aren't all that great in the rain or snow when it comes to taking off.

Nice videos by the way. One of the main reasons why I ask this is to get a sorta standard for a caprice with an lt1 when it comes to power (roughly), to figure out how far behind i am from normal.

When I am stopped (dry, level road, tires normal temperature or a bit cool), I cant get the tire (open differential) to spin at all, even when I stomp on the gas. Tires are winter tires, 215W and I just can't do it. I was wondering if thats the norm.

It will do decent brake stands though, that are similar to mike561's.

The caprice in beat88's video kicks my caprices ass, though I think he was partially on the brakes.

[GreyGoose006]

want a trick to stop the one wheel peel?
parking brake.

there is a hill where i live with a stoplight at the top and the line where you stop is still on the steep part of the hill.

when it rains in the first time in a while, it gets pretty slick with all the dripped oil and such.

my trick is to put the parking brake on halfway.
that gives the open diff a "preload" of sorts, where the torque is equal to whatever torque you have on each wheel with the brake.

just put the brake on, give it gas, and once you are going, pull the release.





thats also a good trick to try if you find yourself stuck in mud or something.
try it before you attempt "rocking" the car or any of these other stupid things people do.






johncrow:
snow tires are pretty soft compound, so you shouldnt expect them to break away easily in warm weather.
also, it depends on your gearing.
first gear in a 700r4 and 4L60E is 3.06. if your rear end is a 2.92 or 2.73 then you are at a disadvantage to those with a 3.08 or higher.
my caprice has a th350 with a 2.52 first gear and a 2.73 rear end, making it nearly impossible to break the tires free.
if i ever do break them loose, the speedo reads about 35 in first gear at half throttle

[mike561]

diddnt know that trick lol
