Yeah, if your ET is bigger than you want, but your trap speed has increased, that should say with a good launch a much better ET is in it. My friends old HPF M3 would run 11's but trap mid 130's because the SMG wouldn't let the boost build to get off the line. The car should have been 10's with ease, but he could never get below a 1.9 60'.

GT-ER

Why would you be shocked? My car spins 2nd all the way to 60-70mph at the track on Toyo T1R's. I ran 12.5@118mph having to let off 2-3 times just so I wouldn't spin out. I'm another one that needs drag radials BADLY.

Let's just say you would run .8 faster, this puts you at 11.7 which is still a slow run for your mod list unless something has changed? Does your car have a H/E and pump? What mode were you driving the car in (dyno mode, traction off, traction on ) This is very important, if you were running in dyno mode if your tires are really not sticking at all you might have been spinning in 2nd gear and car might have early shifted into 3rd giving you a lot of loss in time.

There is a sticky at the top of the E55 W211 forum and it teaches you how to launch and drive the car at the strip.

I would def. have the car in DYNO MODE do a nice burnout on DRs and just try to lean smooth and fast into the throttle when you are ready to go. Remember Reaction time has nothing to do with your 1/4mile time. If you want to run a good time run yourself dont try to race cars next to you as soon as the light goes green, make sure you are ready.

Here is your ANSWER. Hehehe ^^^^ I'm not schjocked I just dont know if the car is capable to spin all of 2nd, but now I do. So without drags you guys cant play.


Good thing to keep in mind is that without DRs making this much power you might get eaten by a stock E55 from the dig. Get those DRs on boys and lets see what that power can really do when it is put down the right way to the ground.

Even on street tires I was able to cut a 1.79. The best way to run it would be with traction control on, with the transmission in sport mode and the suspension in comfort. With all the power you guys are making, you cant just mash the gas at the line your going to have to feather it.. I went to M/T drag radials and the runs are a lot more consistent as traction is way less of a problem.

118 is still low, you got some work ahead of you

GT-ER

If I were to race myself ( stock vs. modded ) I would be dead even by the 1/4 mile mark...after that I would utterly destroy myself.

GT-ER

My traps are probably low due to wheel spin. I raced a CTS-V that trapped the same as I did ( he had traction though, I didn't ) and in the street I pull on him HARD. I even let him start ahead and pull on him anyways.

I'm thinking my car has a good 120mph on it in the 1/4 mile. Which, for being in PR, is pretty darn good imo. Can't say for sure though until I go to the track with some stickies.

hoosier dr's or goodyear eagle ss dr's on clk rims with spacers. as for 60 ft times its not so much the tire setup but how you handle the power until you hook. if your spinning thru 2 gears on streets you need to learn how to feather the throttle until you grip. takes much practice and lots of track time. practice with different rpm launches from idle to approx 1800 rpm on your streets . when you can launch the streets to a 1.8 or 1.9 then the dr's will help you into the 11's. until then you will just blow off the dr's as well. just my .02

Trap was 113

Johncy2000

My cars running really rich too.

320 dreamer

wheel spin will actually inc trap speed. for example... my best time is a 12.5 at 111mph. in ohio at timmayfest i was spinning thru 2 gears with dr's mounted. ran a 13.0 at 111mph. full 1/2 second slower but because the car was moving forward with the spin when i hooked i was gone with the same trap speed

GT-ER

Not necessarily. My past experience ( and most others I know ) is usually the contrary, it actually depends on two things. What tire you use and how much wheel spin we are talking about. Drag tires will tend to lower traps due to their drag at high speeds. Spinning too much tire will also decrease traps due to the car simply not accelerating and you have to keep decreasing throttle input just to get it to hook up.

Most of the time when I have drastic wheel spin I swap out tires and my traps go up 3-4mph ( while times go down by half a second or more ).

As a matter of fact. When my E55 was stock I took it with my bald oem tires and ran a 13.5@111mph. I took it again after I got new tires on ( Falken Azenis RT615 ) and ran a 12.5@114mph. Heck, the 13.5@111 day was actually cooler than my 12.5@114mph day.

GT-ER

You trapped 113 doing 12.5 with 2.2 60' times? That really doesn't add up to me.

AKnight55

Even with wheels spin, you should be trapping a lot higher than 113 with all the mods you have done.. You should be at least around 118-120..

Johncy2000

I guess its my tune then.

Johncy2000

My car is slow

AWOL

wait, i thought it was 118 and even that was bad.

113?! Id kill myself trapping that with all those mods. Something is not right

Hammer Down

When the weather is right bro we can hook up and head to Sac. Until you get DR's don't even bother wasting your gas,time & $$$. I don't run in anything over 70 degrees. Late Sept/early Oct through mid April is the time to run. +100 to -100DA does wonders for our cars. In regards to your tune are you tuned for 91 or higher?

GT-ER

118 was me. I agree there is pretty much no excuse to do 113. That's stock e55 territory.

Yup.

Question, did you dyno your mods before and after? I got about 80whp and 100+wtrq out of my mods, you should be similar.

MBTEK

Tires are the main thing needed here as well as more runs in the 1320,my best run,same day as johncy,was 11.629@119.57, 60ft.=1.749.more power does not equal better times,more power equals the need for more traction,better cooling and a steady foot.Every track is different,Infineon goes slightly uphill,there is a head wind most of the time and you typically won't run really strong until later at night.I made 8-10 passes back to back at Famoso last year,burn-out,stage,run,right back to burn out and running and I went 11.41-11.47 in all those passes,some of the guys that were there couldn't believe it,what heat soak? Point is,with a good set of tires you can put your power down and run strong.I'm running 18's for now but i'll be looking for 16/17's DR's in the future for comparisons.With street tires I could only get 12.3ish at Infineon with the same mods,(quaife was installed as well then),I get about 40+- runs out of my BFG DR"s but it's worth it,I'm not so nice to them on the burn-out.

Johncy2000

I Only made 458whp and 550ftlbs. Its my tune and cooling issue.

Johncy2000

I drove on sport 2 and sport trans with traction on

GT-ER

That's a lot of torque for such low hp. Assuming your cooling system is working properly, I'd say it's your tune.

Johncy2000

Ya i wont get retuned until i get my throttle body and fuel rail kit. So for now running rich is my only option.
