The spacers can be found here:

They cost $350 and they are claiming you will drop around 75° in temp

We will see

Thanks mate

I have driven the C32 W203 and i swear when the car is put in DYNO mode which means no Electronic safety support even ABS the car felt wild like it had more torque in first and second, third was the same in esp off or dyno mode. I usually suspect its the ETS that makes us feel like the car has reduced torque in esp off. but would be nice to confirm if pulling a fuse makes more power!!!

503C43 ////AMG

I plan on running the first 2 passes with the ESP turned off and the 3rd pass with the fuse pulled.

503C43 ////AMG

Just got back from the dyno run, here are the results:



There are only 2 runs on there as they had sent me the wrong run (I had them send it to me through email), the 3rd run was 239HP/230TQ. So it looks like I am putting down what is to be expected at the rear wheel as the only power mods I have are secondary cat and resonator delete.

TEMP = 88°
HUMIDITY = 11%

Unfortunately I forgot to bring my camera so all I have are a couple pics from my Iphone and I forgot to pull the ESP fuse for the 3rd run

Here are some more pics of cars that were @ PSI

Now that the baseline is out of the way I am just waiting for my Evosport UD pulley kit to arrive and then after install it's back to the dyno I will post results ASAP, I am expecting to have the 2nd dyno run in by the end of July.

Good run Jason!!
Did you tell them to put the actual density altitude from the near by airport??? I think its not going to make huge difference but since youre doing base run and comparison between mods, I think its a good idea to set the standard atmopehric condition each time you do the dyno run : )
If you need to know which Airport to use just let me know the address of the dyno place and I'll give you the phone number for automated weather reporting for the airport which will give temp/dewpoit, pressure, density altitude, sky conditions, etc.
If you have an iphone you can download free apps like 'Aeroweather' : ) then just search the airport using ICAO airport identifier (like KJFK for JFK in NY and KLAX for LA international) or by city. These apps will give you current temps, density altitudes, etc as well.
Which dyno did they use??

503C43 ////AMG

Yup, these guys have it all dialed in. They are located less than 10 miles away from the Hillsboro airport so I can only assume the DA they used is as accurate as possible.

I can't wait to see the next few dyno runs. I am sure the gains (if any) from the first 2 "stages" won't be that significant but the headers, x pipe, and high flow cats should DEFINITELY be significant as well as the ECU tune after all of these parts have been installed. Either way I will be the guinea pig for the rest of you guys and then these claims can either be proven or put to rest

Hi Jason.
I couldn't read your chart!
How much did your C43 read for HP and Tourque from the chart list?
These are factory specs right?
You didn't do anything else except the decat mod?

503C43 ////AMG

You mean the chart didn't show up or you don't understand how to read the chart? At the top of the chart you can see where it says "max power" and "max torque"

There are 2 runs posted:
run #1 = 240HP/231 ft/lbs torque
run#2 = 236HP/228 ft/lbs torque

I had a 3rd run that is not posted as I am waiting for them to email it to me but the third run was 239HP/230 ft/lbs torque

The only power mods I have are secondary cat delete and resonator delete, everything else is stock (for now )

KJI3jflarryfe93

Hi J.
Yeah I didn't know how to read the chart, which color lines to look for red or blue?
Your car shows maximum of 240HP??
Where are the other 66 ponies??
Something wrong with your car?

240 HP is different to 306 HP = 66 HP missing??

503C43 ////AMG

LOLOL wow Denis have you been living under a rock?? Just kidding The 2 different color lines are the 2 different runs, each run has 2 lines (the same color), one for HP and one for Torque.

These numbers are at the rear wheel not the crank. When stating that the C43 has 302 HP that is at the crank. That power is reduced through drive train loss (i.e. tranny, diff, etc...) and the 240 HP is what I am putting down to the ground, a real world number rather than a number that means nothing such as the crank HP that the manufacturers use to sell cars.

240 HP is right around what a stock C43 should put down, I have seen as low as 227HP/213 ft/lbs TQ on another C43 but you have to take into account that they may have been using a different dyno, DA, temps, etc...

Either way these are just baseline numbers that I am going to use to track the gains from the mods I am installing.

KJI3jflarryfe93

no prob mate.
I didn' figure out the chart at the beginning.
thanx for explaining für die dumme schwede
livin' under a rock might be comfortable, I have to try it sometimes?

so if you had a bad MAF for instance you would have got less than 240 HP right?

503C43 ////AMG

Dumb no, uninformed perhaps

As far as the HP, if anything was wrong with my car I should have got less than 240 HP

KJI3jflarryfe93

thanx mate

Just received confirmation that my Evosport UD pulley kit has shipped and should be here in 3 days. I will have it installed and another dyno run by the end of July.

Evosport is claiming 8+ RWHP from the UD pulley kit as confirmed by me through a PM to Brad @ evosport

"Will your pulley kit work on the 4.2 M113 in a 1999 C43 AMG?

If so what numbers at the rear wheel can I expect to see?


Thanks

Jason



Jason,

Yes, it will work. You will see 8+ rear wheel HP gain.

Thanks
Brad"

The main reason I bought this kit was because everyone who installed it has said that they rev much quicker which is important for the C43 as it really isn't that impressive below 3000 RPM so the quicker I can get into the meat of the power band the better, the 8+ RWHP is just an added bonus

503C43 ////AMG

UPDATE:

Evosport UD pulley kit is scheduled to arrive on Friday, I will post pics ASAP.

sheinz_57

I am really interested in the pully for the same reasons. I want to get up in to the power band as quick a possible.

Looking forward to the pics.

503C43 ////AMG

As usual the delivery came while I was at work and my wife had just stepped out, I am going to see if I can pick them up tomorrow.

EDIT:

Just had UPS set the package aside and I will have my wife pick it up tomorrow as I won't get off work before they close, I will post pics tomorrow.

503C43 ////AMG

Picked up my Evosport UD pulley kit from UPS today and as promised here is a pic



The whole kit was $375 + $25 for shipping.

The pulleys appear to be high quality and are very light weight. I am going to weigh the kit and the stock components and will post the results. I plan on having these installed in the next 2 weeks and then back on the dyno. I'm just waiting for my calipers so I can be finished with that project before I start another.

KJI3jflarryfe93

did you get the correct serpentine belt for your car?
I recently bought a new Conti belt and the parts number was # 6PK2390
Your's showing another parts number, check with seller if you got the correct belt??

DRBC43AMG

I imagine different size pulleys (smaller) = different belt too

503C43 ////AMG

I am assuming I would need a different belt as the pulley sizes are different from stock hence the "under drive" aspect of the kit

The serp belt came with the kit which was designed for an M113 engine so I am pretty sure it is the right one.

KJI3jflarryfe93

ok, then alles güt .

The 6PK2390 Contitech belt is it only designed for the standard pulley on M113 engines and not for performance pulleys?

DRBC43AMG

Jason, Measure closely your pulleys as they could be the same size as OE which would explain the # of the belt Kowalski is talking about. Could be that Evo used a standard belt as a "model" when doing the picture

503C43 ////AMG

UPDATE:

In the middle of scheduling the UD pulley kit install. My indy is telling me they are booked 2 weeks out so it may a little longer than I was planning but I will be posting results as soon as I get them.
