You are right CharlyE500. I think it is mend to be...Kleemann headers!!
I talk to Cory this afternoon and he told me I shouldn't have any problem programing the ECU as my car is a 2002....only a few earlier models might have a problem. He told me that pretty much, the kleemann fit right in the oem spot with the acception of taking the down pipe out and weld the Kleemann pipe in front of the 2nd cats. He also mention to leave the 2nd cats alone....the 2nd cats only deplete 2hp hence will not make a difference, for the noise level. The sensor plugs screw right in the kleemann down pipe. I also read that, with the Mandrel bends, there will be less obstuction to the flow and will definately feel the difference in the behaviour of the engine.

Good luck ! once you have everything done please post some sound clip !

After all the fip-flopping, I finally pull the trigger.....I was about to check on the ECU in my car this weekend and got an email from gpt....telling me that they have one set of headers left in their warehouse. The price they give me was even lower then the discounted price on the original website and it was free shipping. It was just a no brainer as you can't beat it...hence i ordered it. They also mention about the crank pulley....which is far lighter then the original 2.7lbs vs 6.7lbs stock. I might get that too and install both items together. With the headers and pulley, I believe that will be stage 2 mods right? Has anyone install both items in their car? I would like to hear from someone who has..my indie shop mechanic told me that will really open the car up...not that it is not at the current stock level.

Don't touch the pulley. There is practically no upside and you expose yourself to lots of potential downside.

What is the potential danger using the aluminuim pulley from AMS. Please let me know if anyone has experience with it. I want to do both the headers and pulley the same time....probably delete the 2nd cats this summer and move the x-pipe forward where the 2nd cats reside. Then my mod for this car will be complete

CharlyE500

+1 the pulley don't really do anything in W210. They might try to clean the inventory for good deal but not sure it really will worth it. Few months ago, someone was selling at $350 i decided not to take it because not much benefit.

Schweinhund

We all know that mods are NEVER complete!

I finally got my headers in yesterday. I am still waiting on the pulley which I had ordered last week. When these are all in, will have to spend a day at my indie shop to put them babies in

The horror stories with the pulley are regarding the balance. I have read that they aren't balanced properly and cause damage to the crank/motor.

That being said there are members on here that have the pulley installed and have no complaints. I thought about getting the pulley as well but once I learned that it was a one size fits all (for 5.4 and 4.2 M113 motors) it seemed that the balance issue could be true (AMG has different crank pulleys for the M113's be it the 4.2, 5.4, or 5.4k)

As far as no gains that is a lie. If the weight quoted above is true, dropping 4 lbs from the crank pulley should net some noticeable gains. Not only will you gain power at the rear wheel but your motor will rev quicker as there is about 66% less mass to spin.

just came across this on ebay E430 , E55 Headers $650 Shipped. Item #370589005574.

Allow me to chime in. Having the AMS pulley myself. Don't be scared the only issue the user will have is what I like to call user error. The andy shop has installed them incorrectly in addition they probably didn't use lock tight and torqued to spec (this is on the install sheet that is provided with the pulley) nor did they probably have it re-torqued after a few thousand miles. We drive these cars hard. I have mine looked at whenever I'm in the Andy shop just for safety check. Just with any mod you will have to keep an eye on it.

You can definitely feel the difference down low and up top. with the headers and the pulley on a NA along with res delete/ high flows /x-pipe you are squeezing whatever HP/TQ AMG left behind. Which is not much... For the money it's not a bad investment as the headers are now $650

I'm pulling the trigger today for the AMS headers then Tune then next project

I wonder how much HP at crank with all the mods ? 400hp ? and wonder how will do 1/4 mile. I wish my W210 can make to the 11's.

armaniE55

Good question. I believe I have read that 400hp should sound about right. I've also read that my CF airbox should be good for 5-10 HP. I'll have to get a Dyno run to see.

Fabio D

Yeah Yeah Yeah!! u are the man!! dynoed the car with stock amg airbox vs renntech one!! if it makes 10hp i try to buy yours jajajajajaja also, with ur new brake discs you need more extra hp's

Fabio Daniel

armaniE55

Fabio I told you come to the states and we can race for it

503C43 ////AMG

I have seen several threads with dynos proving the Renntech air box makes 10-20 RWHP on the M113 motor, this is why I am buying one

Mine is shipping out tomorrow

503C43 ////AMG

You will need either 500+ HP OR drop about 1000 lbs to run in the 11's

400 HP @ 3550 lbs = high 12's low 13's

CharlyE500

If i remember good stock runs mid 13's right ? with extra 50hp should get close to high 11's or low 12's.
W211 stock best run was 11.8s but weight 4100Lbs which about 500Lbs more than W210. I have faith that W210 400Hp can do high 11's !

CharlyE500

Lets say at crank hp.
- Airbox 15hp
- Header 30hp
- OE tuning 30hp
- Pulley 20hp
Total 95 + 349 = 444Hp. or lets be more conservative at least around 420hp.

Don't forget to only fuel the gas tank to a quarter full or less for the run. Also, with the resonator delete, x-pipe, second cats delete and high flow metalic primary cats with the spare tire out and only the original rims and not those heavy 19 in wheels....you should be able to get close to the mid 12s no problem

Also don't forget to do the quick ECU reset!!

A stock W210 E55 weighs about 3700 lbs. and will run a 13.3 second 1/4 mile. To run a 12 second 1/4 mile you would need to shave 1.3 seconds off of your time, 50 HP will not shave 1.3 seconds off of your time

The first Audi R8 (4.2L V8) was 424 HP, 3600 lbs, and ran a 1/4 mile in 12.5 seconds. Its about 200 lbs heavier but with 24 more horse power and is no where near 11 seconds.

The C63 AMG is 480 HP, 3900 lbs, and runs a 12.4 second 1/4 mile

Check out this link:
http://robrobinette.com/et.htm

The calculator is accurate within a couple tenths, using the calculator and the 3700 lbs + 400 HP you get about a 12.9 second 1/4 mile which sounds pretty accurate.

Like I stated before you would need to be @ 500 HP+ or lose about 700-1000 lbs to get into the 11's.

503C43 ////AMG

This HP addition is a common misconception. When the manufacturer states adds "X" amount of HP it doesn't necessarily mean at the peak, they are stating the maximum HP that is added.

Example:

lets say the headers add 30 HP but it adds the 30 HP @ 3400 RPM but your peak HP is @ 5800 RPM where it is only adding 15 HP. You can't just add up the total HP that is claimed as it is added at different points in the RPM range. No doubt you are going to have more power but it's not like you add up the numbers and add that to the peak power rating.

Got my pulley in today. Will be coming up to have it install in a few weeks. This thing is super light and shiney

Schweinhund

The car I really go with is Abalone's E55. Before he supercharged it he only had Kleeman headers, exhaust and an ECU tune. I think he made over 400HP.
