  1. The springs on a set of heads are good to .475 lift. The cam exhaust is .477 with 1.5 rockers. The heads are from a roller cam. The new cam is a flat tappet. Rockers will be stock 350 vortec rockers. Will the springs hold?

     

    Get the springs the cam calls for.

  2. Just to be clear, did you measure the inducer or exducer of the compressor wheel? This is important info. Thanks

     

    Inducer.

     

    This is a decent turbo but it needs rebuilt. It WILL work the way it is but it's not right. The compressor wheel has left some amount of wear in the housing, we ran it for a few years without issue like this.

  3. you aint missing anything. that place is like taking a trip back to the 50's in the most run down burger joint you could find.

     

     

    Thats the point, its not modern. The food is great, they have breakfast food that is unlike anything you can get from a chain. It's diner food.

  4. No Cruise Control.

     

    I'm tracking an interesting idea concerning the turbo building pressure and forcing the tb blade open, raising the RPM, raising boost, raising RPM, raising boost...

     

    No, thats not going to happen or work. You could run that thing at WOT 20+ psi with no BOV and go from WOT to closed and it would spin the turbo backwards and never move the blade.

     

    I have seen shitty throttle bodies have the blade flex under vacuum, bit its just enough to cause a mild surge. The TPS is interesting, however I dont know how much air the IAC could move, and the iac should be closed under higher TPS voltage to be able to feed air if it needs to (it wouldnt be wide open). Maybe a short in the IAC wire?

     

    A vacuum leak would be unmetered air and odds are it would just sputter and pop and not rev.

     

    Any chance something is catching the throttle cable? Not enough slack and maybe a bad motor mount causing the motor to twist in gear pulling the throttle open?

  5. Yes. What you need is a torque wrench that will let you measure drag torque in ft/lbs via dial or beam. You'll want to measure total drag torque before you pull the pinion nut off, replace the seal, then retorque to achive the same drag torque. I always used to pull the axles, if there is something that is creating more drag than the pinion bearing it won't work, then its a shit shoot (pull it apart and put it back together and hope for the best).

     

    The correct thing to do is to replace the crush sleeve.
