I ran the RENNtech C63 the other night in the ACR, the C63 ran 11.6 @ 125.3 MPH, I was going for the launch and couldn't catch the C63 in time...

this is the highest C63 trap so far?

Dads C63

CONGRATS on your time and to Renntech!! I know that conditions were great!! Those MPH's are HUGE!! Good luck and hope to see you both at PINKS.

can't wait for someone to hit the 130's N/A

Dad will probably make it once he gets that stroker kit.

What tires did you run this time?

Looks like you cut a better 60'/ET on Nitto NT05s a year ago. -> http://www.dragtimes.com/Mercedes-Be...lip-17712.html

Wow...now I know why you guys thought my ET and trap were "slow" when I ran ion Dec, ha ha. Of course, my car isn't modded quite like that C63. Nice!!!! Congrats, RENNtech!!

What are the mods on the RENNTECH?
What tires were you using? DR or street tires?
How do you guys launch the car? ESP completely off? I tried a few times and I am getting major wheelspin if I power brake even up to 1K.
Do you just hold the brakes without pressing the accelerator and "gently" feather the throttle to hook up that good.
Mashing the throttle quickly is just a recipe to vaporizing tire tread?
Excuse the questions if they appear rather newbish but I only had my C63 for a few months and would not want to dissapoint once I am at a light with a competitor

Is that a serious comment or a sarcastic one?

I think he was Serious

I called them today to ask abt this exact car they said it have shorty headers,intake,tune,82mm throttles they will offer them for sale next month and some light weight wheels and O.S limited slip...

congrats. winter is a great time to set records beacause of the high air density.

11.6 wow.

c63 for ever.

Lol I said the same the same thing when I first saw the slip. Then I saw the driver listed on dragtimes and didn't want to say anything

Great speed! But what happened on the slower time? There was a list of mods but no mention of the different mods between the two runs.

What mods were added to create another 4 mph?

Better weather, bigger throttles, better tune, etc....

RennTech is one of the great tuners out there and they've been doing amazing things for the 63 lately....

I thought it was somewhat established that the 63 doesn't need larger throttle bodies though? I dunno, I mean nothing can argue with that trap speed...I'm impressed! But at the same time, I don't know if weather alone can be responsible for the huge gain in trap?

mthis

U know beter then me but I would think a car traping 125 should be alot faster in time then what he got. What u think the nittos did him dirty lol

MB_Forever

It may not need the larger throttles, but it is sure liking it

I ran 13.0 @ 109 mph in bad weater and also ran 12.1 @ 118.9 in great weather in the same exact car, same exact driver, same exact gas, etc.... So to answer your question, weather has a lot to do with it especially for naturally aspirated cars.

blackbenzz

Well I ran a 10.6 @ 125. It should be quicker with a trap like that. Did you see who the driver was? Hartmut, the owner of Renntech. Could be the tires, I dunno

ET was killed by the 60' time. If that car had hooked hard it would have an ET near Dad's 11.2x

blackbenzz

Yup. 60' is usually a reult of two things: Tire and driver.

juicee63

Great race.. You almost got him.

Thats a powerful 63 , jeez.

The 60 ft aint that bad, looks like a low 11 is in the future.

hhughes1

I am wondering if the larger TB's mechanically lean the air/fuel ratio. Most every tune that I have seen other than MKB maintains a semi rich ~12 af erring on the side of forgiveness over maximum power.

emericr

Are u guys ignoring my questions further up ?

alqamzi

You will find the mods up i wrote them.I think they are using nitto's invo am not sure though.i launch my car at 2500RPM ESP sport hope this helps...
