    Spring vs Nitrogen To Pressurize Shock

    Good evening. So you have a shock with a floating piston in a chamber charged with nitrogen used to pressurize the fluid. What are the advantages/disadvantages to using a spring behind the piston in place of the nitrogen?

    Adjustable Proportioning Valve With ABS

    Actually I was thinking about increasing the pressure to the rear brakes.

    Adjustable Proportioning Valve With ABS

    The car is an 01 Jetta. The ABS system is an electronically controlled OEM system that controls all four wheels. Each wheel has its own speed sensor. I believe the split is front to rear.

    Adjustable Proportioning Valve With ABS

    Where would you install, pre ABS controller or after? I am thinking before (being in between the master and the EBCU so that everything was working correctly. What say you all?

    prevent sludge in 2.7 engine

    The most common problems with these engines are timing chain/tensioner/guide failures and engine failure caused by sludge blocking the oil pump pick up screen. If I remember correctly, the timing chain tensioner is oil fed and the sludge problem contributes to that.

    Fork Mid-valve

    That had some interesting information on it even though they were only concerned with dirt riding.

    Fork Mid-valve

    Which is a better configuration for use with the "mid-valve", a check plate and a spring or a shim stack? The application would be street/road racing. I have always seen a spring and a check plate, but I recently heard that Honda has ditched this on the CBR1000RR in favor of a shim stack. I...

    Fuel Pressure Regulator

    The Barry Grant step down device is not very sophisticated. I thought it tied into the ignition and had some type of "map" based on RPM's, but all it has is a WOT switch and a manual bypass switch.

    Fuel Pressure Regulator

    Barry Grant sells an electric control unit that drops voltage to the pump at lower RPM's for the same reasons you stated above.

    Fuel Pressure Regulator

    It still has a regulator, it just has it in the tank. As for the pulse width question, I do not know.

    Fuel Pressure Regulator

    I have seen the dampers. If I remember correctly, Chrysler had a recall on the Caravan to install the dampers. I would call the in the take configuration more of a bypass setup, similar to an OEM oil system than a return style system. A friend of mine is plumbing up a fuel injected motorcycle...

    Fuel Pressure Regulator

    Thanks for your input guys. I have always thought that the return configuration was superior to a non return setup for the fuel temperature reason previously sited. The reason I asked this is that in the past few years I have witnessed fuel injected Japanese sport bikes go from utilizing a...

    Fuel Pressure Regulator

    With a fuel pressure regulator you can go two ways, return type or non-return type. Without factoring in the ease of not have to plumb the extra line for the return style, which setup is better? Is one better for carbs vs fuel injection?

    MOTO GP VTwin

    It is not that I am saying not to try invent the wheel too much, is is more like don't try to re-invent them all at once as it is very easy to get overwhelmed. I think that is one of the things that really hurt Aprillia in their attempt in MotoGP. They just had to run all this high tech stuff...

    MOTO GP VTwin

    My advice would be to start out with as much conventional technology as you could at first and pick one area to develop at a time. If your main objective is to developer the engine then use a conventional chassis with Ohlins forks and metallic springs. It is very easy to get caught up in...

    Nothing secret here. Get up all the cash you can and steal Valentino away from Yamaha.

    Do you want to know the best thing you could do for this project?

    Once you get this engine built, what are you going to do for a chassis?
