    my bonnets melting :( turbo bags

    If u put vents, they usually sit 1/3 of the way up on ur bonnet.. when ure moving forward that area has the lowest pressure above it, making it effective to suck underbonnet air out

    I actually used a kit where u thread 2 layers of heat resistant material with stainless wire. Looks a bit noddy but did the job well.

    Wastegate positioning

    1. Avoid having extra flange joints pre turbine... so no gate adapter plates. 2. Reallistically u should have the gate either off both branches, if a log manifold, one off to the side is fine. The turbine option is ok, just ensure its welded right. lol at the pissing contest though..

    Painting of racecar

    have you looked at plasti dip? not a show finish, but meant to be resilient, and easy to apply.

    Digital boost controller/GM map sensor

    your wastegate shouldn't really be partially opening... maybe something else is a bit off?

    Digital boost controller/GM map sensor

    make your own. use one of those digital pressure sensors, run 12 V to it, and hook the output to a 1/4" valve..

    What creates a rough ride?

    not necessarily - only if you're referring to cheap suspension. 1. ensure the car is not hitting the bumpstops. raise on 'low' springs not superlows. superlows arent stiff enough to compensate for lowered ride height 2. shock absorber tuning. with good adjustable shocks, you can adjust the shock stiffness, depending on specific driving condition. bigger piston diameters can also get better control, without butchering the ride quality. name of the game is controlling high speed rebound / compression. 3. vibration + harshness from the bushing. blame nolathane. replace with std rubber. 4. wheel + tyre weight. heavier wheels have more momentum, therefore will work your suspension harder.

    Barra DOHC vs 4.0L OHC

    just use the btr auto, and buy the harnesses to run a std ba computer. i'd love to see a 6spd auto in an xf though..

    having trouble with my engine

    dont refer to the balancer cos the outer can spin.. spin the engine until end of compression stroke (thumb over hole), and you can use a screwdriver (big handle so it doesnt fall in) to rest against the piston dome, and observe when the piston passes TDC. set the timing off that. --i dont think the engine can run on 180 deg out timing (especially gas), so chances are you're not too far off

    HP Limits

    a single 3/8" line will support around the 220 rwkw mark (so 300hp). incidentally, that's the flow limit of many standard type gas tanks.
