running slicks for first time... stock 2000 WS6

**PAT-LS101** · 07-16-2008, 07:24 AM

Hey guys I just got a 2000 WS6 w/ 99,000 m6 2nd owner and now its time to go to the track with it, its stock except for a K&N filter I also have a pair of micky thompson E/T streets My question is what should the tire pressure be? and what RPM should I launch at? Im going for 13.2 ive seen it so many times with stock WS6's hoping I can get there lol any advice would be great thx!

You still have the stock 10 bolt? If so I wouldn't be running those tires or launching hard.

If you are on the stock 10 bolt, use the tires for traction down the track, not out of the hole.
The 10 bolt will more than likely pop on slicks.

If you were running them on a solid rearend...air pressure depends on the size tire. Probably around the 16PSI range though for those.

I have a stock 10 bolt on street tires what psi should I be at?

20-22 will help a little.
There is no set tire pressure. Each tire will be a little different.
No burnouts on a street tire, just turn the tires over once to clean them off.

You kinda lost me though, you started the thread talking about slicks.

wtf.. don't run a street tire at 20 psi. That car would probably go faster running the ET street at over 20psi too.

**boofthese** · 07-16-2008, 01:05 PM

fuck it launch it at 6k, and kiss your rear good bye LOL

**PAT-LS101** · 07-16-2008, 01:07 PM

yeah it was started about slicks but u were saying the stock rear end wouldnt take the hard launching with them on so thats why I asked about street tires

dont wanna blow the rear end up! lol

Why not?

Still plenty of air, flattens the patch out.
I don't run street tires, but several friends do and always have had better luck right around the 20-22PSI mark.

They are not designed to work at that pressure range. They will have less total grip because they will want to cup and use the outside of the tire more than the inside. Go lower your tire pressure to 20 psi and do a huge burnout, see if your tires are worn evenly. Your nankang street tires are not designed like a wrinkle wall slick no matter how much you want them to be.

To each their own.
I don't run a street tire...even on the street. Just going off the information friends have given me on that one.

20-22PSI seems like plenty of air to avoid the 'cupping' though.
26-27PSI is what I run my fronts at (275/40/17 BFG KDW's) and they are wearing perfectly. Not looking for a wrinkle wall effect with a street tire, just a little more contact patch.

I run my Hoosier's at 15PSI passenger and 16PSI driver at the track. Those...do wrinkle.
To and from the track they are at 22PSI.

My 'everyday' rear tires are 315/35/17 Nitto DR's. 24-25PSI. If anything, they wear center first.

What are you basing your advice on?

Nothing. You are just making stuff up based on what your "friends" do. Tires are designed to operate in a certain pressure range. Take them out of that range and they operate poorly.

You are the one with 500+ rwhp that barely runs 11's. I think I'll listen to your advice.

I run my slicks at whatever they work best at on the particular day I am at the track. Try doing that one time and the car will work better.

Ever ran with a DA at 7500?

I don't like hitting my head against a wall.

Track is 5800 feet up.

Everyone tells me to move, but I rather like it here. Just that racing sucks.
Feel free to rip my car for 500RWHP and 11.97. It really doesn't matter to me. I built it to enjoy. Not for you or anyone else.
Dyno SAE corrects.
Track does not.

As for the 20-22 PSI....we will just have to agree to disagree. I don't have the time/money to go out and burn off tires to prove it either way.
I never said it was my experience either. Always said it was what friends had luck doing.
Is it correct?? Obviously debateable....seeing as 3-4 guys here seem to have great luck doing it.
Maybe it is just the lower profile wider tire.

I run my ET Streets at 14psi typically (have gone as low as 12psi tho). I don't see a problem running them with a stock rear if you slip the clutch instead of just dropping it.

**Bottesini** · 07-16-2008, 10:17 PM

I borrowed a set of ET streets from a friend of mine and I actually ran slower since I was not used to them and the tires caused me to bog. The next day, with a little better weather (hotter but less humid) I started cutting the same 60's almost and started to get better times overall. With my BFG G-Force sports and with the older style KDWs I found for me they worked best with a really short burn out (long enough to drop then clutch and get on the brake) and at 20 PSI. The contact patch might be lessened some at, but I have had thoughts that the lower preassure takes some of the shock out of the system. Whatever the reason I go faster at the track with 20 PSI compared to 35.
