For those who wonder is there away to get more "FUEL" for Clk without upgrade ECU. The answer..YES!

<br>
I find out to day that the Clk had a fuel pressure regulator and also had a return fuel line. If you want more fuel, you can by adding another fuel pressure regulator on the return fuel line by the fuel filter and you also have to re-route the menifold vacumm line. I believe Kleeman.com have the fuel pressure regulator but i don't know if they would sell it without the supercharger kit.<p>

Another FPR?

Adding another FPR will make the fuel delivery faster on the fuel line, but all in all, the ECU still limits the fuel that goes into the valve.<br> <br> So while a larger FPR will make fuel delivery faster, I don't think it'll necessarily deliver more fuel as the ECU still regulates the fuel mapping.<br> <br> <p>3KGT220

Arnee...the ECU control the duration (time)injector open. So by increase the fuel pressure through..

<br> fuel pressure regulator. What you are doing is forcing more fuel into the engine at the same duration (time)when the injector is open-up. Example: If you force air into a ballon at 5 psi for one minutes and force another ballon at 10 psi for one minutes. Which ballon do you think is bigger (more air). You only need to reprogram the ECU if you still need more fuel. And even if you still need more fuel then you would have to chnge the injector itself combine with reprogram ECU. <p>

I m not 100% positive about mb design, but...

the computer should be able to determine the amount of fuel being injected into the cylinder. therefore jsut because you increase the fuel pressure, does not mean you are increasing fuel delivery, because your computer realizes how much fuel is going into the engine. i believe all this will accomplish is faster of fuel into the cylinder, but not more fuel. <br> <br> second of all, why increase fuel unless you have forced induction? shouldnt you be trying to limit fuel or advancing timing?<br> <br> but like i said, im not sure how the mb ecu works...<br> <p>threshold6n.jpmorgan.com

I would assume that if you added another fuel pressure regulator, you'd need to reprogram ECU to

take advantage of it.<p>ca-brea5b-192.stmnca.adelphia.net

by simply increasing the pressure makes no difference in volume of fuel introduced...

into the cylinder. as long as the terminal pressure point is reached the marginal benefit from any increase in pressure after that is minimal. you would need to get bigger injectors imo to introduce more fuel this way...or better yet the ecu fuel remap would be a better solution. let the computer handle the fuel delivery. :p<p>

GUYS !!! I'm sorry to say this but "YOU GUYS DON'T KNOW WHAT YOU ARE TALKING ABOUT" Call this.....

<br> company. www.kleemann.com. They just came out two supercharger kits. One for Clk 320(kit $9,000) and CLK 430(kit $14,000). Or pick up a european car magazine. Both cars are feature in this month. I personally call them and talk to them about the 430 kit. I were very interesting in this kit because i were kindna regreted that i did not try looking for a used CLK 55 when i bought the 2001 Clk 430. Believe it or not but there way of getting more fuel to feed those extra 135 hp were through just pressure fuel regulator. They did not even have to re-program the ECU. Now, what do you have to prove that the theory of getting more fuel to the engine can not be possible through fuel pressure regulator!!!!<p>oduass3.qualcomm.com

King-man..There were something think about use NOS on their car...and they were asking for help....

<br> to see is there anyway to get more fuel into the engine. You don't just add more fuel to a stock engine.<p>oduass3.qualcomm.com

I've had my eyes set on that Kleemann kit for months now. Can't wait for my issue of EC to arrive.

They mention for the C-class..you have to change the fuel"pump" to get more fuel because the....

<br> factory fuel pump does not provide enought pressure.<br> <br> <p>czavala.qualcomm.com
