So I'm curious to find other members on here who 350 wrhp + in there c43 or c36. I would also like to find what areas they are in.

Why? You want a race Just kidding.....

With WRHP it is meant 'rear wheel horse power'. Shouldn't be the shortcut RWHP? Or is there another definition in USA as in Europe? It is confusing me since long.
Form my power diagram I can tell you, my engine power with 5.5 engine is 396 bhp, nominal power DIN is 402. My rear wheel horse power is 262,4.

To obtain 350 or 400 rear wheel horse power, the engine power should be about 600 bhp or more, I believe?
Or is the power loss more or less the same if I would install a Compressor on the engine (f.e. 400hp=262rwhp, 400+100hp=262+100rwhp)?

I'm fairly certain he meant 'RWHP', to show power at the rear wheels (as opposed to at the crank).

I think you will find North American tuners will only show WHP in their tuning figures, as opposed to crank figures.

Ehhh its a bit different.. Stock W211 E55 469 motor = 410-420ish rwhp.. Its usually a 8%-12% loss from the crank to the wheel. From what I saw on the dyno, correct me if Im worng..

This should be a short list. The only 2 I know of putting down 350+ RWHP for sure are you and Motorsport3 (370 RWHP), money-one might be close...

503C43 ////AMG

It's actually closer to 20% with an auto tranny. MB played down the numbers on the 55k motors, they have to be closer to 500HP at the crank.

I put down 240 RWHP, my motor is rated for 302HP at the crank

302 * 80% (20% for drive train loss) = 241.6

I am now making 350+ RWHP, but am no longer in a C43....



I did have plans to swap a 55k motor into my C when I had it.

Oh boring. Measuring each others' horsepower dicks are we? *Le sigh*, I feel like a black sheep trying to race these cars, others just prefer to put shiny rims on them, take pictures and discuss the cars over coffee...

503C43 ////AMG

You are too cool for school!

Some people are into racing others are into aesthetics, is one better than the other? To each their own.

If you prefer racing great but if you have nothing constructive to add to the thread then don't post...

aghakauve

Thats some what true! My STi had 370 to the crank and it put 304 to the wheels so yea (that was a 6-Speed) But it really depends on what dyno your on as well.

HAHAHAHAHAHA

If u r looking 2 run
Next time u r in fl hit me up

austinholloman

I had 350 WHP in a dream the other day but I don't think that counts... I'll check back in here after this winter's make over though. ;-)

jumph4x

Not trying to start flame wars, trying to find like minded folks. To each their own, yes. I just wish this side of the preference had more than 3 members on the whole forum.

Ok here is a different opinion ( I read all topics but I just dont have much to add to them). I enjoy having stock hp in my c36 it is fast enough i can understand that there are people who would like to have more power but still i,m happy. I enjoy just cruising my amg, somethimes I go to Germany with my dad we enjoy the no limit autobahn. My stock c36 keeps up with all kind of cars new Porsches Bmw etc we did 260 and still had rpm left this is where the old amg can show off what it still has left it keeps up with very fast modern cars. Actually from a 0-100 the difference aint even that big with a c63. But some people just want more than this so they swap the engine to the 55 they are free to do this i,m sure it is a blast to drive with the swap. But for me it is even without it. ps my dad also had a w202 c180 with a 1.8 engine 125hp and even this car does 200km/h + without being afraid that it explodes. My dream car is the w202 c36 I enjoy it very much wouldnt trade it for a c63 amg. Everybody should just do what he likes with his OWN car

503C43 ////AMG

I guess if you call 2 seconds "aint even that big". If that's the case the difference between your dads c180 and your C36 0-60 aint even that big either...

ProjectC55

I would definitely run your car if I was living in Fla which may happen very soon. I can't see a CLK500 running with my car especially in the mile. Can't see it! He's making 350rwhp and you want to run him?

w202mylove

haha i dont think 2 seconds are that bad difference between c180 and c36 is 5 sec

503C43 ////AMG

I was thinking the same thing... Unless he's not telling us something he would get CRUSHED

buffyclk500

if u win it would b all in good fun
but i know it would b a good race

importfan21

Ladies, ladies, it's all about the power-to-weight ratio. I've shaved a good 100lbs off my car and still getting lighter. A 55 motor or supercharger would be nice, but the less weight makes the car go ever so slightly quicker.

jumph4x

As Colin Chapman noted adding power makes you quick on the straights but adding lightness makes you quick everywhere else. Unsprung weight out the door first.

DRBC43AMG

+100%

ProjectC55

If I win? Bro I mean honestly do you really believe it would be a good race especially after the 1/4 mile?

RBYCC

The RWP differs depending on the type of dyno used .

A load dyno which places resistance on the rollers to better simulate a road surface usually shows about a 30% drivetrain loss on an automatic Merc.
About 5% less on a manual transmission Merc.

The inertia dyno which has free spinning rollers would only show about a 15%-18% drivetrain loss.

There are other factors that when dialed in can effect the RWP...car weight, ambient temp and hunidity are a few
