    • Weistec Stage II supercharged 2008 W204 C63 AMG drag strip results and comparison to naturally aspirated results

      This W204 C63 AMG belongs to BenzBoost member charliekay. He took his car to the same drag strip when tuned both when naturally aspirated and when supercharged. Previously, he ran 11.8 @ 119 when naturally aspirated with an OE Tuning tune. With the addition of the Weistec Stage II 2.3 liter twin screw supercharger his elapsed time improved to 11.1 and his trap speed increased by eight miles per hour to 127.33.

      That is a solid difference right there especially considering the forced induction run was in warmer weather. @charliekay's full impressions below:


      Hello all,

      Last night I finally got around to running the car, after a couple of busy months.

      Very impressed with the times, and gain overs the N/A setup.

      The car has the following:

      - 2008 C63 with Original Tranny
      - Weistec Stage II Supercharger w/ Oil/Air Seperator
      - OEM multispoke 19s on front, w/ OEM Conti tyres
      - OEM 5-spoke 18s on rear, w/ MT ET Streets 265/40
      - Full interior with no weight reduction
      - Pump Fuel - 98RON (equivalent to 93R+M/2) - I only ever use BP Ultimate 98
      - iPE Full Valvetronic Exhaust

      N/A the fastest the car ran was 11.803, this was with the iPE Exhaust and OE Tuning Stage II tune. Unfortunately I cannot find the timeslip for the 11.80 run, but I have one for an 11.83 run I did, which was 1.849 60ft, and trap speed was 119mph

      For comparison reasons, I used the same car, same wheels (including rubber), same fuel, same track (Sydney Dragway), same exhaust, all with full weight.

      Obviously it was a different day so different temp, looking at the different time slips, looks like there was a 10 degree Celsius temperature difference between the runs, last night being hotter. Not sure how much time this equates to, but just trying to be 100% clear with the results.

      So last night after the Stage II was put on, I ran 11,205, 11.181, 11.184, 11.184 again and the last run was the fastest being 11.162.

      This mean the Weistec charger took a minimum of 6.5/10ths off the N/A time. The reason I say minimum is traction is a problem with that much power, you can feel the car hesitates and jumps a little when it hits second. I think some 16s or 17s with better rubber would be worth 1-2/10ths just in solving the jump into second, not to mention the gains in weight reduction and 60ft gains.

      Anyways here is the time slip.

        Content overload... what is going on?

        Awesome results! I'll promote this to the front page ASAP.

        Congrats, nice run. Its amazing that you were able to trap 204.92 ~127.3 with stock wheels. One question though, why did you use 19inch wheels up front? why didnt you go with 18onch as well?

        Two reasons:
        1. I didn't think there any substantial weight difference between the 18s and 19s to justify taking the 19s off. Maybe 1lb all up? Correct me if I am wrong please, I haven't actually weighed them.
        2. I wanted to a direct comparison between the car pre and post supercharger, this mean't running an identical setup. We have seen alot of info on the power increase that a supercharger brings, but noone actually knows what that equates to down a 1/4 mile, now we know.

        I would probably say that if I had my 19s with PSSs on yesterday the difference between N/A and Supercharged would be alot less down the 1/4 mile. Daily I have alot of traction problem WOT with the PSSs. The blower bring alot of power that the car can't put down. With the MTs, the traction issues were substantially less.

        Also, to give an idea of a comparison with other cars, last night there was a worked 997 911 Turbo which ran 11.0, a worked 2013 GTR, which ran 11.3. I think there may have been a problem with the GTR because I have seen stock R35s run at the same track, which normally go 11.3-11.4.

        The diffrence is about 2kg per wheel ~ 4-5lbs!
        I have a better idea for you for the fronts that will help you elapse a quicker time :-)
        PM me.

        Take my advice that I will PM you and put some race fuel in your tank next time. You will be in the 10's barrier for sure.

        What time did he run with that 60ft?

        Very nice Charlie! Your car will easily run 10's with a better tire setup. Glad to see you are enjoying the car and putting the power to good use!

        No, no, you misunderstood. It's a good thing. There's just a ton of stuff going on all at once right now.

        This is the only picture I could find from Wednesday night.

        I have other pictures I have taken of the car, but none at the drags.

        That is from the website of the official event photographer. It comes watermarked.

        I have to buy the photo to get a non watermarked version. Still waiting for their reply.
