i don't know if they are different. If they are, it would only be that they are a different size to fit a slightly different size airbox.

 

pocholin... The CLK 55 are also like that. I'm confused. I don't know to take my K&N,s out and put the AMG"s back in or not. I'm sure Mach430 doesn't run the K&N's. If you have about 500HP who needs 5 more? I have messed with car's all my life and I have never heard of such. I had a foam filter on my 454 Chevelle and it dry rotted in less than a year so I really don't think foam is the way to go. I know there are a lot of new products out there. I hope Evosport comes up with a new intake( I guess that is what they are calling them,we used to call them air cleaners,the intake is what sits between the heads) Sounds like the underdrive pulleys are the safest way to get,or excuse me free up HP!!! I am thinking more about this upgrade and it's not that expensive, about $500.

 

I'd keep the K&N filters in since they last almost forever, and they still clean better than the AMGs
5 hp estra on a 500 hp engine miht be woth 0.050 on the quarter mile, so they are with it! Every little bit helps.

 

It all adds up.

 

GBD, put reflective insulation on the bottom of the airbox, and if possible wrap the inlet air pipes, that should be worth 8 hp. like bluewinkle said, it all adds up.

I followed what you did regarding insulating the airbox on the E55 (on the thread regarding clk and E55 performance). I also modified the tabs on the bottom side of top of the airbox (I hope that makes sense). I also wrapped the intake hoses to the airbox with the thermo tec heat barrier. I then removed the flimsy plastic grill cover that was obstructing the flow of air into the intake tubes. I replaced the stock air filter with K&N. I can truly feel a difference in the car after these modification. I have an old Vericom that I tested 0-60 before and after the above modifications.

Before the modifications, the 0-60 (at night, temp 59 degrees) was:

run 1 5.33 (traction problems)
run 2 5.67 (traction problems)
run 3 5.10 (some tire spin)
run 4 4.95 (some tire spin)

Average of all 4 runs is 5.26. If you delete the worst (#2) and best run (#4) , then the average of run #1 and #3 is 5.22

After the modifications, the 0-60 (at night, temp 61 degrees)

run 1 5.12 (some tire spin)
run 2 4.99 (some tire spin)
run 3 5.30 (some tire spin)
run 4 4.66 (some tire spin)

Average of all 4 runs 5.02. If you delete the worst (#3) and best runs (#4), then the average of run #1 and #2 is 5.06.

I have not yet done a 1/4 run, b/c I can not find anyplace flat enough or safe enough to do 1/4 test runs. All I do is turn off the ESP, hold the brakes with the left, and press the gas with the right. If I do feel the need to brake torque, then I lightly, very lightly, brake torque the car to around 700-800 rpms (otherwise, I spin like crazy).

I do not know how accurate my old Vericom is. However, I can certainly feel a difference in the car. For less than $200 (K&N and Thermotec Adhesive backed heat barriers) and a couple of hours of my time, I gained an average of .20 in the 0-60 of my car. If that is accurate, then I assume that I gained around 15 hp. I think I can go faster, but traction is the problem. Next project is to change the spark plugs and then dyno the car.

 

jcjmw, great, do you have pics of the inlet pipes? I had done mine, but looked terrible, so I decided to remove it, may be you did it a different way I did and looks better.

Very good numbers even if you spun tires. Once I get my car back from the shop i'm going to redo de airbox, cut those tabs inside the box, and re-wrap the pipes.

 

ok, I'll try to post pics here. Having a hard time downloading pic from the camera. In the meantime, I am trying to find other "cheap" ways to improve the car. Do you have any ideas?


Oh, one more thing, a guy from HPS is coming to Las Vegas, Adam, with their company car - a supercharged E430. I am thinking about supercharging my E55 (subject to approval from the wife). Adam and I are suppose to meet when he is in Las Vegas. I hope to test drive the supercharged car.

 

Make sure to ask him about if intercooler is needed (in his opinion), warranty, and performance gains, how much and why so much? LOL

 

Why not just sell your 55 (or the engine) and buy a 430? You can put a Kleemann supercharger on it for the same price (after trading motors) and have about 10HP less on the 430 than the 55 would with the HPS supercharger. So you end up spending the same, getting the same power, and having an intercooler and aftercooler when you're done, and everyone loves an intercooler

 

What do you guys think about Evosports underdrive pulley set?

 

I like them

 

But do you love them?

 

You know if you aren't going to SC your car, I believe it might be a good thing. I know it frees up HP, but any HP to the rear wheels that was not there before the mod. is extra HP!

 

The pulleys really do get 13HP at the rear wheels, which is $30 per whp. A muffler may get 3HP at the rear wheels, and is usually about $200 per whp. An intake, say priced at $600, would get about 13HP at the wheels, and be $46 per whp. For the money, the pulleys are the best bang for the buck.

Thanks

Ben

 

i "LOVE" mine

 

LOL!

 

But then I won't have an E55, besides I want my E55 to be an E55K

 

yeah i mean its only money right?.....

 

yeah! I money I don't have right now

 

pocholin... It will not be to long till CHRISTMAS!

 

Are you going to get me a s/c for xmas????

Its wortht the try, isn't it?

 

I'll talk to Santa for both of us. I'm going to tell him you have been GOOD!!

 

Thanks, I hope he belives you, because he didn't belive me last year, worst of all he had proof!!!
