![]() ![]() They are totally pointless on a turbo car, so I dont think I have any kicking around, but I'll go look. Only way of testing that is by fitting a non-ecu controlled escape for the air, a dump valve. No idea if that was on or off throttle (though I never went about about 1/8 throttle, but with a stupid electronic throttle like Mercs have what you are pushing and how much the thottles actually open is often very different), as it MAY be the boost spiking as the throttle shuts as it now has nowhere to escape from, and unlike a turbo its a positive displacment unit so it cant just escape back out the inlet. I think maybe depressing the gas pedal helps to get the engine to turn over. This has happened to me twice and on both occasions I was stuck in a parking lot for about 20 min before the car would start again. The engine just wont turn over until after a few tries. The car idles just perfectly without it, totally normal, id almost go as far as to say it idled better.īUT! Could I test the car without it? Could I hell! The minute you even lightly tickle the throttle above 1500rpm, the blower pressure was enough to blow the (very tightly jubilee'd in) bung out like a ****** rocket. The starter sounds fine and the electronics all seem to be fine. One things for sure, the common internet rumour (as clearly nobody has ever actually tried!) that the bypass is needed to make the car idle, as when the supercharger is de-clutched the supercharger is blocking the inlet air flow, is total and utter ********. Well, just removed the bypass throttle and plugged the hole. I made a tidy A-pillar mount for it that matches the rest of the Sport trim, but until I can find a place to run the pipe it's not much good to me! Well, hooking it up to the inlet system is incredibly easy, but finding a hole/grommet/anything in the bulkhead to run the pipe, well, it's beat me so far! I have just been hooking up the gauge for testing only and running the pipe thru the door, then removing it once im done, 2min job. Wouldnt be surprised if Mercedes electronic throttle mapping is preventing us from getting full throttle at all times despite what our foot is doing, but unfortunately SprintBooster don't affect that.īoost gauge install is a pain in the ****. It suits some people who rarely use full throttle as it gives more throttle without them pushing the pedal more, but if you use the full range of throttle, it does owt. The moment I put the Air Conditioning on high, and placed a load on the car by placing it in reverse, I heard this loud rattling which sounded like a mechanical warp. A few weeks ago we had some extremely hot weather in Southern California, and for the first time this season I used my Air Conditioning. ![]() Ok ive started the engine with the hood open and i can hear a noise on acceleration and deceleration, ill describe it best i can, it is coming from just behind the oil filler (grey rocker cover between the radiator and the oil filler, that area of the rocker cover, not the red rocker cover area) i would describe it as a slack chain type of noise, i say this because the timing chain on bikes sounds like this when the cam chain adjuster is wore out, is this normal? I think the car will need to be under load for it to leak real pressure, there is no obvious hiss.Complete waste of money IMO, and I've used one in the past.Ī gimmick to make your car feel faster when its not any different by making the throttle feel more jumpy. 2004 W203 C230K Supercharger Pulley Rattle. Would it be intermitant though, if its a split pipe on the S/C, with your suggestions of diagnosis that is, if it is leaking some were, would it give me an engine light? Surely there is a sensor monitoring the pressure? If the S/C is worn or wearing out would that give me low pressure and make it loose power with no engine light? I need to sort this out, my last bill for the air injection valve and to wipe the code and reset the engine management was £240!! Is there a work shop manual (book is better IMO) i need to get my overalls on and the jack out and start testing bits!
