    Official **Pirates of the Carribean 2 ** Thread

    I gave it a 6 out of 10. Good flick, but alot of acting to fill in just for fodder and nothing more. Not to mention I waited through the 20 minutes of credits to see "bonus" footage. BOOOOOO!

    Why not higher compression ratio??

    Boss: slow your typing down. I can't even read what you just wrote.

    Paint Questions???

    I want to paint my whole car but I don't have the cash for all the targa seals, rear light seals or the trim that I know Im going to break. But yes, paint the whole car.

    Why not higher compression ratio??

    Unless the engine is tuned, you run race gas all the time, and you have a very large and efficient intercooler I would say no. 10:1 to higher compression with boost requires a build engine also, and exotic race fuel such as 115 race gas, alcohol, or toluene.

    Why not higher compression ratio??

    Yup. If you could cool the intake charge and not be limited to pump gas you could run 12:1 compression engine etc etc with X lbs of boost without problems.

    Is it me or is my car lazy

    Ive had the same problem before - turned out to be a vacuum leak. Vacuum leaks = boost leaks = WAYYYYY rich = not wanting to run.

    Turbo don't like higher oil pressure!

    -4 max oil feed line, -10 to -12 return WITH VACUUM BEING PULLED.

    Turbo don't like higher oil pressure!

    You can not run massive amounts of oil pressure to a turbo like that. Either change to a carbon front seal or make a restrictor going into the turbo.

    What is your wastegate set at?

    You can hit the key switch in less than a 1/4 of a second? 31psi boost spikes happen in a blink of an eye.

    Help! I'm being a douche about my Supra!

    If it cranks, fires and then dies - check the AFM if you're turbo.

    SnackPack dare me?

    Yeah those things last for years... they are pasturized and vacuum packed.

    Some specs on my buildup... feedback requested

    Sounds good, but you won't do over 600 with the 61mm compressor wheel. For the drag turbo I suggest something over 74mm with a Q trim or larger. For the valves I would suggest going with Ferrea. Cams, go with WEB cams or TODA out of Canada.

    checking my logic

    As long as you've got good hardware and you have your fuel tuning top notch...

    Turbo tech

    No. The 10psi would create less a chance of knock because of the intake air charge would be colder (in theory) than the turbo making the same HP at 15psi.

    Turbo Gauge not working...

    Make sure its boost signal hose is still attached (vacuum hose to manifold)

    checking my logic

    Stock headgasket and ARPs I've heard of going into the 450's but not lasting long. The commetic head gasket will take up to and over 1000hp... ITS VERY PICKY ABOUT SMOOTH SURFACES. You will need to have the block and head completely torn down.
