hi every one, i have been working alot on my car and i never gave it a dyno due to the fact that the only dyno available in Lebanon that i know of is getting a major overhaul, and might not be finished until mid next year

my car is a 2001 clk430, with amg air filter, brabus cams, evosport pulleys, platinum spark plugs, amg c43 middle box and rear with gutted cats, also i have a custom remap with 1.0ms advanced timing and more fueling. i also have 18" Rial Daytona Racing wheels which are quite light i believe that i have 310~320hp max with around 430~440Nm...am i right?

i have raced the following cars and won the length of the race is around 1000m...

C43 rolling start at 20mile/h : 3 car lengths.
C43 stand still start (1100rpm): 5 car lengths.
several 2003-2005 350Zs from stand still 3-4 car lengths.
1998 SL500 rolling start at 50mile/h : 5+ car lengths.

these cars are all stock so the comparison to be accurate...

i have tried the gtec pro 0-100km is in the 5.7-5.8 due to traction issues, what ever rpm i launch on the car looses traction on 1st gear till the middle of 2nd gear....

also i reached 260 km/h and i still had around 800~900 rpm till redline (6200)...

i really dont know how much hp/Nm i have and would really like to know your opinion...

 

the C43 should smoke your a$$ every time. are you sure it was a C43 and not a C220, C240, C280, etc etc?

 

no its a C43, i have seen the engine

 

Stickers add hp....you got any?

 

ya i have the one on the amg air box, maybe 5 hp

thnx for the sarcasm...

 

This guys asking for some serious answers..hes not being an *** to us so can someone try and help him out without being sarcastic?

We have somehow turned straight to sarcasm instead of being sincere...I know I will probably get flamed for this but oh well. I liked the it before when we would help out everyone. OK maybe I have had a little too much caffeine

"butt dyno experts needed!"

275hp is standard at the crank. You're pushing 290 tops.

 

Happy?

 

thanx, but the "butt dyno" term i learned from here... thank you for your help ...

 

mmmmm Yeah much happier LOL

"In the old days, before we had dynos on every street corner, we used a formula [(.00426 * MPH) ^3 * Weight] to determine horsepower. A 3500 pound car with that trap speed seems to point to 291 HP"


Found this, but I dont know how much distance is involved in a trap speed. Is that the same as a quarter mile?

 

Greetings

do you mean i should see how much my car gets the maximum speed in 400m (1/4 mile) and plug it in the formula provided?

 

Assuming that "trap speed" = 1/4mi speed, Then yes. I don't know if this is wheel hp or crank, or what kind of error this has.



I don't know if they're the same but it seemed like what you were looking for.

If you can't find what a trap distance is you could always find the 1/4 times of a car with a known hp and weight and tweek the constaint in the formula to work with 1/4 miles or prove that trap speed is quarter mile speed. This all would work the best if you used a stock 430 as the basis for finding your constant. ( this Is all off the top of my head so anyone please correct me if I'm wrong)

Worth a try if your really curious.

 

well i am really curious cause u know i have put some tuning parts on the car, but u really cant add them up... like the cams are rated for 27 hp crank, the cat gutting maybe a 5hp, remap another 10 hp, and the pulleys are rated 6 hp if i remember correctly, and maybe the air box a 3hp but really u just cant add them up so was wondering if it was well worth it... now i got stock m113 manifolds and working on making them into a headers... hope the exhaust shop know what they r doing!!!! also i am toying around the idea of getting a 500 m113 long block and putting all my stuff on it... because they are dirt cheap here like 800-1000usd for it... if i get a 31 hp/ and 70Nm more from the stock 430 m113 and if put my stuff "hoping" they get another 40hp / 50Nm i think i am in stock e46 m3 territory?? am i thinking right? also i have a good deal for a V9 vortech supercharger... but still doing my research... i think i will need a 500 m113 torque converter... still all ideas...

 

Sounds like your having a lot of fun with your 430 mods, I kinda wish I saved up for a v8.

I think if you used this method consistently as you modfiy you should be able to determine how effective your mods are. I would think that it would be important to go to a track for your speeds if you don't want your results all over the place.

On that link I gave you in the proformance section under "judge for yourself" the guy got 290 hp for a stock 430 using that formula with a 102 mph trap time. He also got 245 whp on a dyno. So there is your stock numbers, now compare your trap speed(assuming that 1/4 mi). See what you get.
