It's not your ONLY problem, in reality your Trap Speed will actually go DOWN w/better 60' though you def will run quicker just not faster. 117 mph is telling you your rigs wayyy down on hp/tq but believe what you will Prof
w/your mod list you should be Trapping 125-126 mph @ the very least in the high 10's w/good DA etc.. What was the DA & Ambient track temps? You're running near Stock trap speeds..
My bud Clayton Benzorama here, ran my EXACT OE Dyno tune w/spdrvn TCU on otherwise bone STOCK SL600 @ 11.0x @ 126-127 mph on stock 18"s w/dragtires on rear, though he had big heavy 20"s up front.. IE No other perf mods... Your SL is way, way, way, down on hp... And again for stubborn ears DragTires do NOT increase Trap speeds, they make your car quicker, w/slower Traps. It will launch harder w/slightly slower overall trap. You also need to ditch the big heavy 20"s in front they're killing speed/too by adding massive drag resistance etc Unsprung weight advantages can add up to 2-4mph & drop 2-4 tenths off your final 1/4 etc..
Put snow chains on or buy some w/ice spikes lol...

If I remember right I had the intake temp around 140 F/60C* before the run and after the run the IAT rise to 176F / 80C*. So I think its normal.....

First I must test the car which better tires... When its dont spinn any more and I have grip Im gone look at the time and if Im not happy then new tune.
I was able to keep the gas at the bottom first after the half way. Its run strong after that!!

I now what the probleem is... Far to slippery! I need 90% more grip. I must have ESP on al the way.. : ). I run with old Camaro turbo. He had 11,5 and I lose directly from the line. He had at 60feet 1,5 sek but I catch him the last 1/8 mile and we have nearly the same top speed 117,5 mph. So honestly the power is there ... : ). My race start after the first 1/8 mile.: ). It was at airfield track.
So what kind of tires must I buy.?

Ahhh yup.. each Tenth of a second in 1/4 mi run roughly equals 1 car length, Ekselent would be trailing behind by 10 -11+ lengths in reality since he ran a full second + slower but in Ekselent world they were even @ 1/8 & both finished w/same exact 117mph wat a load of

Of course he was before me over the line and when I get grip I start to reached him. ESP cut the power long way for me from the start: ).. . That track was to slippery for my tires and power.

If I had ESP off my car and the trottel at the bottom the car should be spinn the whole ****ing 1/4 mile. The car run HARD when I get the grip!
Belive me or not the power is there ! In yours and at my same ****ing world!
I'm not worried about the power level at the engine. : ). When I had the ESP off the car start to spinn in 60-70 mph speed (EASILY) also with booth ****ing tires . It wouldnt do that If I had probleems with the engine!
Do you get it!!!

Your Trap is the TRUE hp test & 117+mph for your mod list is horrible, you should be Trapping 125-126 mph @ the least... Guess something's wrong w/that Hot Air Intake piping
& obvious those huge dog bowls wouldn't be any good w/hooking a decent 60' but still ALL your Trap speeds are junk... Betting your Tune's extremely rich beyond CAI problems..

Today I got feedback from Finnish BMW showroom. I wrote there yesterday regarding my race because I own an M5 and X6M to. After I leave the track there had been an Mercedes SL 55 AMG. Stock with stock tires also. Only 13 sek times...

Few years bak when I read your threads I directly recognize you are a clown.... Small litle poor clown... Not even an idiot.... A clown : ). You are affraid if someone is better than you!!!! You are so childish that I thought first you are 8 year old... : ). I think also you are not even married because nowbody can be with you for a long time..... Maybe a dog??I think you are a man which dont want that somebody is better than you. If you are so much better than (we) other is tell us now what is your best ET ? If you have more power than benzorama you must be a better driver than he is because you have also bigger shoes even your foot is small with uggly CAI so you must bet ramas time.... So you must be under 11??? If you dont we are disapointed : ).
Seb.... Im older than you.... I have seen a lot more of the world than you... And you are the first person which I now who are affraid as a litle child if some body is better than you.
Sebastian.... All what you write dont boother me at all... When you open your mouth my reaction is just the same as my daughters 1.5 year old little man... Hahaaaa : ).
Seb..... Do a bigg favor for the 90% forum memebers.... Dont comment anything at al because you behavier very bad... : )
Get your life and go furher..... Im 100 % sure many of us is gone love it : ).
Next Im gone buy better tires and Im 100% sure im gone drive low 11 next time..... Hahaaa we are fine without you and your own secrets... You now what I mean... Hahaa : ).

Okay I try to explain again.
-60 feet our diffrence was 0,482 sek
-330 our diffrence was 0,643 sek
-660 our diffrence was 0,611 sek
-1000 our diffrence was 0,6 sek
-1220 our 0,591 sek
1/4 our diffrence was 0,62 sek
(My topspeed 117,5 and his 118 mph)
My car spinn three times before the half way.
So our diffrence was going smaller and smaller before the line.... I hold up a litle before the line because I laught for my self because I had no grip. I slowed down three times at the race before I get 100% grip at higher speed. : ).
The Camaro run many times and the best time was around 11,5 sek ...
And his car dont spinn at whole time because he had good small tires.. He dont even drove the car to the track. He bring it with a trailer.
Im 100% sure if I had same grip he had my car is faster for sure.
So what is the probleem to understand this??

I do see your point that you should have the power to do the 11.5sec. But this does not rule out other possible issues. Go again to a prepped strip and let's find out. You should get a Dyno done just to give you confidence in your tune.

Finaly someone who understand what I mean.
.Any advice what kind of tires.... I spoke with a GTR "service man" and he recomend Toyos 0?? If I remember right.
I need also new rear rims.. I have the oem wheels but they have totaly wrong ofsett.
Regarding the dyno... My nearest dyno is about 300 miles from me : (.
We have a high school closer and I have heard they have a dyno there to so Im gone call them today and ask can they dyno my car and which standards they have...
Im happy because the power is there (and the boost is also there 21,7 PSI)... Only thing Im worried about is the A/F ratio.

With wheels for 1/4 mile go as light as possible. If you want just drag wheels go small with big side walls and M/T drag radials
If you want a daily driver HRE wheels are fantastic and can be customized to and offset needed. For tires in my opinion the best all round tire would be the PSS but for more grip for the 1/4 mile and dry weather performance the pilot sport cup2.
If you want a daily driver tire but more focused to drag performance go with Nittos. They do a 345/25r20 if you have 20" wheels.

Thank you.
I want to keep my dailys and buy an another setup for the track.
My Michelin is too slippery... pointless to spend time with them at the track.
I have been the all day at online and try to find out the best setup for the track. You are right regarding the side wall and so on.
I think 265/40*18" tires is nearly the same as OEM in dia.
I'm going to call a company and ask which brand and so on.
( ET Street drag radials).
I have call two different dyno workshops today.
-The nearest have a Rototest dyno. They take of the wheels and install the Rototest at the axle. Booth axels.
Show lower hp / Nm than others.
-The second has Dynocom Dyno ( roller dyno). Its about 450 miles from my house.:roll eyes:
I think I'm gone bring my car to the Dynocom Dyno. Rent a trailer and bring the car at the trailer and let my X6M do the jobb.... I can dynoed my BMW X6M also at the same time. They can tune also the BMW ECU but not Mercedes ECUs. He was not sure what "kryptons code" Mercedes ECUs use?
Does anyone now?
Dynocom workshop can do the dyno next Thuesday if I want to.
I must decide it tomorrow...

I would try to go more like 285/35 which was the stock tire on my car. I am sure M/T or Nitto do drag tires in that size and you have to run 20psi or sometimes less depending on tire and car weight.
I am going to try some 305/35r19 which are larger than stock however I feel we have sufficient torque to turn them. I have to use the 19" due to 380mm brakes on the back.
