I did a 0-60 MPH run in the CL65 today
I finally got around to trying a 0-60 mph run in the CL65 this morning on my MT ET Streets (cold with 30PSI). I quickly came to the conclusion that I need way more tire in the back to do much better.
Currently I have to slowly roll into the throttle to keep it from smoking the tires, even with the soft DR's. I can't go full bore until I hit around 20mph. Anyway, here's the baseline starting point.
More power will definitely hinder the street-launch right now, as traction is the limiting factor.

A well prepped track and getting the tires up to temp makes a huge difference. If you are looking to hook on the street you might have to try and find some VHT to treat your tires with.

I could never hook my 65 on the street from a dig at all! From 50 on dr's was ok. I could break traction and set the ESP light off at 80mph with my michlens in cool weather![EEK!](https://mbworld.org/forums/images/smilies/eek.gif)
Looking forward to see some track times from you

Yesterday when I ran with the DR's, I had the car raised up. This morning I tried on the street tires with the car lowered and raised. On every launch, even when rolling into the throttle, the tires broke loose. It their defense, it was pretty cool out. Anyway, none of this morning's runs were under 4.3.
My goal with my Crossfire was 3.8's on street tires, and the best I every got consistently was 3.9's. I'm definitely going to need some soft 305's for the street if I intend to get this beast down to 3.8's.
With the power this thing is making, I think 3.5's would be possible all day long if it hooked up without rolling into the throttle. Now that would be something. I think I'd need LSD and fat "R" rubber for that to happen. Just dreaming a little I guess.

The set up cost a few bucks, but I have it in a stock look and I love it. You can still roast the 305's but they make it a little easier to feather the throttle when the LSD is making both tires play fair.

Keep em at 30 psi for for a lil stiffness in the sidewall so you can still take turns but if it want it on kill for a street race then your MT's will hook much better with 20-22 psi.

Since the track is closed tomorrow, I might just drop them down and try for a 3.8.

You don't need 305's to hook on the street, I used 255/50/16 hoosiers in 65- deg ambient air on street using tiny 16x7 clk whls (my sl was making 565whp 690rwt at that time) traction light would blink for a micro second bet all gears, as close to dead hookin' on city streets I've ever seen! It will slam you deep into the seat, a slingshot type acceleration comes to mind from a dig.. Tall 50 aspect ratio sidewalls are needed.. ![thumbs](https://mbworld.org/forums/images/smilies/thumbsup.gif)
For comparo I've ran my 18x13 ccw setup w/345/30/18 BFG G-force Drag Radials & couldn't hook for sh_ite from any gear on city streets.. Even in mid 70 deg temps (sl was making 630 whp 730+ rwt)

On the street drag radials are better, but no comparison of a water box burnout (heat) and VHT on the track. In the end we are complaining of having a car well over 700 ft/lbs of torque. No reason to mention 16" clk wheels that won't fit over 65 brakes, besides making the car look like garbage. Everyone has their own balance of look over function. I can understand for the track but for hooking on the street and daily driving, drag radials will be gone in no time and mix matched wheels don't do much for me. Like everything else, you gotta decide what works for you.

True.. But from another 65 member on here 17" Bogarts will fit the 65 REAR rotors, and who cares what ugly drag setup rears look like? Not like he's going to a car show in them lol.. Just sum fun on the street is all.. Either way great traction can be had on the street w/proper setup..

I'd be very surprised to see 16" wheels fit on the back of the 65, as the 18's are only clearing the dust shield by a minisule amount. I did have the Hoosier 255/50-16's on lightweight CLK wheels back when I raced the XF. They hooked and booked, but I sold them when they wouldn't clear the rear CLK63 calipers I was running.
Anyway, hopefully the ET Streets will hook at the track, since I rather not deal with the headache of replacing what I already have on the car. After I burn up the street tires I'm currently running, I will likely go with something much stickier. Actually, the new Michelin A/S 3's were amazing on the XF, so I'll likely go that route.

I'd bet dollars to donuts the 17" Weld RTS would clear. Many thought they wouldnt clear the CTSV and ZR1 brakes, but they do. Combine them with 325 M&H Racemeasters and you have a mean hooking tire, even moreso than MT's. A few guys with stock blowers on CTSv's have recently run 1.3 60' with the M&H's

you are completely wrong. d/r's have super soft sidewalls to allow the tire to flex and grab. 100 tread wear is normal for d/r and most street tires have a tread wear in the 300 to 400 range

I wish you'd stop holding back and speak your mind Steve. I can't wait to beat up on the P-car. I know, that's not gonna happen. Even with two turbos and 6 more cylinders, that Porch is gonna be too far out of reach.

While we're on the subject, does anyone feel their CL is actually faster than stock from a dig with a tune on the street? I rolled into full throttle today from around 40mph and at 55/60mph it started breaking lose. Truth be told, I think the car will likely be much slower under 60mph until traction is addressed.

Naturally, comparing how the two tires drive on the street isn’t calculable like a time slip is, but rather, it’s all a seat-of-your-pants opinion. We were able to log plenty of miles on both tires, and found the stiffer sidewall of the 18-inch tire to perform similar to an OEM street tire,
Quoted from: http://www.stangtv.com/tech-stories/...eet-radial-ii/
Yes d/r's have softer side walls than OEM tires but the are stiffer than bias-ply drag tires. My point was the 18" d/r's he's running have stiffer side walls than 15" d/r's.
