A few friendly pointers on using ET Streets
1) Never drive in the rain unless you have to. I typically can't go over 30mph in the rain. On occasion I have been able to get up to 50mph. But if you hit some water you will kick out the rear before you can even react. So don't go over 30mph in the rain. I have driven 50 miles in rain once. I can feel the back kicking out.
2) Always get a little water on the tires at the track, your posi will thank you.
3) HEY I was doing my burnout and my car was starting to go sideways. That means they are hooking. <img src="images/icons/smile.gif" border="0">
4) How much PSI say for 16" et streets? I'd never go below 16 and higher than 22 on the track.
Or your posi is getting old, and spinning one tire with more torque than the other.

As high as possible and still get traction. If I had to go as low as 10-12 psi to get traction, I'd do it in a heartbeat. <img src="images/icons/smile.gif" border="0">

5) Be careful where you drive. Those tires are VERY soft and cannot be patched. I actually had a small rock push it's way through an ET Street one time (brand new tire too <img src="images/icons/frown.gif" border="0"> )

Mark the tire with shoe polish where the valve stem goes. Check after each pass. If the tire moves on the rim DO NOT lower the pressure any more.
Johns right, water is scary, even a little rain is dangerous.
If you run wide tires on the front, keep the inflation pressure high on the rears for street use, like 32psi. Lower the fronts to the same.
If all your dash lights come on, don't sweat. The ABS freaked out because Streets are bigger than your front tires.

<strong>Roll into the water and spin 1/2 second, then roll just out of the water.</strong><hr></blockquote>

Think about it. When you park in the water hole and spin your rear tires, what happens? Water gets slung all underneath your wheel wells. What happens to the water in the wheel wells then??????? It drips BACK ON YOUR TIRES. Result? You spin off the line.
Also getting sideways while doing a burnout is a result of not enough rpms at the wheels. Stick guys should try to dump it in 2nd and get the rpms up there. Auto guys should try to shift into 2nd(starting in 1st) after your rpms are up there. More tire speed is better for the burnout.

This way I don't spin water up into the wheel wells (I agree, bad idea) but I do get %100 water coverage on the tires which makes for an easier burnout.
I have seen some people just back into the water box and then pull straight out again and end up with only half the tire surfaces wet. This sometimes makes for a clumsy burnout. This is of course more common with a narrow water box or one that isn't as full as it should be.
Right in the center of the tire.
I was positive that they wouldn't because of the tire composition, but they did it.
No probs whatsoever so far.
I run 15 lbs at the track.
<strong>I just blip the throttle very quickly just to barely spin the tire over one revolution.

This is pretty key IMO. If you get unequal water on the tires, like say NO water on one, you will get one tire fire.
Good points on going sideways, yeah that can absolutely mean the posi is dying.
I want to stress again how dangerous it is to drive in the rain on ET Streets. If you try to be a hero and go say 45mph in rain, you will not be able to correct fast enuff if the car spins out.
When you start going really low on tire pressure you run the risk of having the tires cup and really maybe you need to look at the car (if the track is hooking for others). I've seen people bitch about cutting a 1.7 at one of our private track rentals and I am like whoa dude the guy after you cut a 1.52 <img src="images/icons/smile.gif" border="0"> .

You're right, it's more like a "Blip" I've never really timed it. Like Stephen said, I just spin enough to get water ALL around both tires. Seldom do I see more than a light coat water in the box at our track. I do NOT drag water down the track. I hook better with wet burnouts than dry, so water dripping probably isn't happening.
If you are running stock hydraulics on a stock clutch, be careful about 2nd gear heating. You may spin the clutch instead of the tires. Been there, done that. 4.10's and aftermarket clutches may not have the problem.
About the "not enough RPM" theory to sideways burnouts, I never start my burnout at less than 5000, but when there is not enough water in the box is when I get sideways. So I do know that not getting both tires equally wet will always cause walking.

<strong>As far as patching goes, my friend had a screw go thru his, and Discount patched it up.

Actually I had mine patched too but the tire guy said that as thin as they are the heat from a burnout would go through the tire and cause the patch to lift off. I ran tubes after that and never had a problem. On the other tire, I too picked up a screw and didn't even try to get that one patched - just added a tube to that side.
About driving in the rain. I got caught in a rainstorm on I25 between Denver and Fort Collins after racing one night. The rearend was all over the place even at 30mph. I finally ended up driving on the shoulder till the next exit and sat at Wendy's for about 3 hours waiting for the rain to stop and the roads to dry. It was unbelievable how much I was sliding around.
