    Getting around a turbo restrictor requirement

    From what I remember Toyota created a device that was attached to an intake part, that when not bolted onto the engine unfolded, probably some linkage mechanism. But when off the car looking at it youd think nothing off it. When this device opened up it moved the valve that regulated boost. No...

    Figured out the CG problem, I think. Just figured out an estimate for the roll angle desired, then applied the lateral forces at the contact patch. Gotta be an easier way. Anywho, the effect was noticable. Have you seen a way to roll, dive, and steer at the same time. BTW I'm in love with the...

    Yeh, but I'd also like to control the magnitude of the force at the CG in order to get to a particular point in roll, or pitch for that matter

    Only able to add a external force to the wheel it seems.....

    Graphics->Screen Display->Static Only Still trying to figure out how to add a force(to the cg perferrably) and see the result.

    Have you seen a way to add assymetries? Maybe able to do it in the templates, but that seems to be for 1 side only

    Kingpin Inclination, Caster, etc. for McPherson strut

    did you have the rim with an offset far outside the wheel center? How well did the design work?

    Kingpin Inclination, Caster, etc. for McPherson strut

    I would think it to be very hard to get zero kpi AND zero scrub on any front suspension, but it sounds like a good guideline.

    Suggestions or advice please.

    Greg, can you draw a free body diagram comparing a grc and fbrc, in roll would be perfect.
  12. red300zx99x

    Suggestions or advice please.

    I'm still lost to what the difference is, never seen anything concrete about a force based roll center. This report comparing the 2, is it open to the public? And another thing have you ever seen anything written about what the driver feels in roll? And the car with the different rears, did...

    Suggestions or advice please.

    Yeh Greg, what the deal. Force based roll centers over geometric roll centers right. Still waiting for a better description of such, better yet you working one out for everyone to enjoy. Def not being a smart ass here, just wanna know some things. Good day mate

    Lug nuts loosening on older aluminum rims

    I had a car stolen a few years back and had some 'shoes' on it. Police found the car and it was on cement blocks. Low on cash I headed over to a local junk yard. Searched and searched and searched until we could find a set of wheels that used my bolt pattern. Oddly enough one was found off an...

    ROLL CENTER FORMULA HELP

    2d or 3d. 2d is easy, intersection of lines. 3d your dealing with planes more, but yeh 2d or 3d. Also what type of suspension and what are the given inputs, be happy to work this out over the bb

    ROLL CENTER FORMULA HELP

    I have such a formula. 2d or 3d?

    paint to cover stainless steel

    Powder coating should do the trick. Aslong as the surface is roughed(sand blasting proobably) and the complete surface is coated the coating should not come off. I would also assume that it should have little to no effect from the sea water, the coating basically puts a shell of plastic over the...

    SPRING FREQUENCY

    hope you can decipher that.....i need sleep

    SPRING FREQUENCY

    If you note on page 589 the first equation Kf equation then the third equation K. Now set Kf with the front ride rate of 384.4, now for K use 384.4 for the left side and the right side rate. These 2 equations are equal, showing that the right and left side have indivdual rates. Now under the...

    SPRING FREQUENCY

    Thats what I thought, but Milliken on pages 588-589 makes that assumption odd. He uses a ride rate of 271.2lb/in at first, then changes that to 384.4lb/in. But then in his roll rate calculation he uses the same value.....as the ride rate for each spring. If the front ride rate is 384.4lb/in and...
