    This is great! I run micro in wasted spark and fuel on V8's. So I assumed it would be pretty capable on a 3cyl. Had no issues firing off 220lb hi-z bosch injectors either. I'd think LS coil packs...

    Sure, I datalogged exh. back pressure as well.

    What I’m saying is even if you changed to a 3” primaries with a giant collector pre turbo, your back pressure wouldn’t change much, since that’s not...

    I wouldn’t worry about the factory Exh manifold in a turbo application. Generally, the restriction is always the exit on the turbo volute and the Exh wheel. Not the manifold or pre turbo piping....

    Appreciate the help and suggestion. Just didn't have access to a 04-05 RXP camshaft. I'm new the lingo, thought you were talking about the aftermarket big $ cams. I grabbed one on ebay.

    Thank you!

    Adjusting slip on X-charger? Shims?

    Installed a new X-charger. Pulled it to check slip after about 5 hours. Its slightly below 10ftlbs. Made 10psi or so. Seemed to run fine. Don't see wear or heat in it. What is the best procedure for...

    Def. not here to argue. I know diddly about PWC. How many hours do the 4-tec’s usually last? I come from a drag racing automotive background. Valve springs most definitely lose pressure over time and...

    The supertech 85# springs w tit. retainers were on sale, and cheaper than OEM replacement springs. Thought I had read OEM were 75# on the seat? Either way, easier on valvetrain to have lighter...

    Appreciate it! I'll take a look tonight. Is it better in your opinion to grab some light weight aftermarket valves or stick with OEM if you aren't pushing higher than factory RPM? I had already...

    Thanks.

    Is it pretty common to just change the chain and not the cam/crank gear? I was under the impression these "match" with wear so if you replace the chain both gears should also be replaced?...

    I was in the same boat as you last year. Eventually it wouldn’t even run after a couple minutes. I had visible spark at all 3 plugs, so I assumed all was good spark wise and spent weeks chasing my...

  17. Timing chain differences? 420898040 VS 420898042

    Any difference between these 2 Pn's? Parts manual calls out for a 420898040 for my PWC (07 wake). Have a 420898042 on a shelf at a friends. Can I use this?

    thanks.

    Don't plan on swapping ECU's or revving it any higher than factory, so prob won't mess with cams and such at this point.

    Water Box removal (07 wake 215)

    Any real reason to run a water box? Can’t I just replace it with a straight pipe?

    Only real gain is noise suppression (which I could care less about) and stopping back flow if I were to land on...
