Hi c63 Community !!

My car have secondary cat delete and Carlsson Tuning ( Best Tuner in Germany ). I have 550HP.

I drive 19" original Wheels with Pirelli P Zero Nero 255. Tire Pressure is like Stock.
It is verly hot and the track is not so good ( airport ).

Yesterday i ran 12,30 - 12,70.

To day i ran only 12.80-13.10 i verly have no Idea why and tomorrow it is elimination.

So i have a vew Questions:

1. Do i need normal or lower pressur at my tires ? How much would be good ?
2. How i get the car cooler it has all the time about 105 C" ?
3. I think i get the best times with Sport Traction Mode and automatic in sport ? Do i could make better times with other modes ?
4. Do i need to start with food on gas and aqbout 1000rpm or should i start when the light comes and then hit the gas ?
5. what race radials i could use can i take 17" with performance package Brakes ?

I think i could make on a better track a 11.70 or something but i also think whe i have more traktion i even get come in low 11.xx .


I hope you can help me first for tomorrow.

Get 17 inch rims with hoosier dot drags. 275.40.17

run 10 litres of 91 or 94 oct gas and 10liters 110 race fuel.

Esp off. Manual mode.

dont stall it up for longer than 2 to 3 seconds or it will pull timing.


take the spare tire and all that junk out. Front seat is easy to remove with 3/8s 12 point.

Shut car down in lane and open hood wide open. Out ice on intake manifokd to cool it down.

Removing psi on a street tire will do little to nothing. Dont do a burn out as you will make them greasy and fill tread with water. Water plus vht equals slippery.

I have all my times even the verly good ones with burnout. So do you think without i get a better time ? The track is not perfekt dont i need the burnout to get the dirt and little rocks away ?

Merc which 17 inch rims did u use

Merc63

I found some cheap replica 17inch rims online for 200bucks. They worked.

Go around water box, spin tires over gently infront of water box to remove grit/dirt.

Try with no burn out see what happens.

hahahaha. yeah Ok!

Merc would these 17 inch wheels clear the rear brakes ?

mr747

Could u show me the link please

Merc63

Im not sure the website it was years ago.


to op, drag racing on street tires is pointless. 90percebt of the race is made in the first 60ft. Youre at a huge disadvantage.

Alwoody

Dont understand that. Maybe some strange humor in Katar.

Thank for the Tipps. I made it and get the second Place !!

The best times i get with a burn out and without water !
