Stock times in sig.

 

I don't know the specifics yet but i know someone with a green filter and an '06 SLK350 hitting 13.89 on the 1/4 mile.

 

Hahaha, I take it that's me once I get used to the 1/4 mile and lower my R/T? Yeah it was the third time I've gone in my life...

 

Wonder if the ECU would know or the ET's would benefit from running racing fuel.

Old mods- We used to run a "cool can" filled with ice/water that a copper spool the fuel ran through on the side of the fender in the Hurst Olds. Good for 2 10ths. Pulled the 150lb front bumper at the track for another 10th of a second.

 

the Hurst Olds.

What year was the HO. A friend has a mint restored '68 HO.

SLK350

SLK55 AMG

 

I'm curious as to what the new 300 HP SLK 350 can do.

 

It was a '73 special order car from the east coast. I had so much fun in that car street and strip. Best e.t. was 12.36. I was also one of those "bad people" who street raced out in an industrial section of San Jose almost every weekend. I can't believe the 55 is comparable because the 55 just doesn't *feel* fast have owned the Olds. On slicks the Olds launched hard enough I got light headed from the acceleration force. Of course the down side was that the car cornered like an oil tanker.

Boy the 55 needs more tire... ;-)

What kind of Honda bike do you have? Have a 05' CBR600rr that's good for mid 10s 1/4 times. Does like your olds will snap your head back if your not ready for it.

Nice to see I still have the quickest N/A SLK55

only mods at that time was Green Filters and M/T Drag Radials

What kind of 60's were you getting with the DR's Bill?

 

Went again today with my new 19" 360 Forged Spec|5ive wheels. It was only 83 degrees outside, but the car ran slower I did 3 passes and they were all pretty consistent at 14.4

Also, I realized that the 1/4 mile times printed on the slip takes into account the reaction time. So in post #1, it actually took me about 14.55 to go from start to finish. So overall the car is 0.2 seconds slower.

Oh and every time I've gone, I've gone with a full tank. Next I'm gonna clean the Green Filters, run again, lower the car, run again, and finally try it on an empty tank.

 

Couple things to consider...

First, your larger wheels are most likely heavier than stock. Not only are they heavier but since they are a larger diameter, more weight is located on the outer edge. This makes a car slower overall.

Second, if you are lowered, even with alignment, you will have a bit more negative camber which means your rear wheels are not getting full traction. This also will play a part in slower times.

The few times I've ran at the drag strip, I've mounted my stock wheels. Perhaps you should try the same.

 

SLK 280 1/4mile time?

anyone has info for SLK 280 1/4mile time???

 

Thanks Bill. Heading to the track for the 1st time this year on Saturday, if the good weather holds. I'm getting low 1.9s on street tires, so maybe at some point I'll try the DR's - good to know there's another couple tenths right there alone!

 

60' times were in the High 1.70's to Low 1.80's & .1xx RT. Think I have one of the time slips posted on dragtimes.com

Awesome numbers, Bill! :tu: Is there any way you can tell
us a little about your launching and shifting techniques?

 

I know this is a old post, but I just took my 2007 Slk 280 to the track last night 1/13/2016. I had a full tank of gas.Here are my results:

R/T .O87
60' 2.413
1/8. 9.787
ET. 15.060
MPH. 92.95

The only mod are K&N filters. I was hoping for a better run that the 15.060 but being my first time ever going to a track,but not the worse.. A lot of fun.

 

Interesting. I've never done the quarter with my SLK280, but your ET and trap speed are just about identical to what I did back in 1998 with a bone-stock 190E 2.3-16 with Getrag 5-speed.

 

I think I can do better next time out. I thought I could do 14.7 but next time I'll just have 1/4 tank of gas and take the spare tire out. Any thoughts on how to get a better time I would love to know.
