Re: HMT NE DYNO DAY!!!!!
Good luck Josh.
PS, bring some fresh ------- plugs, so when those old sanford and sons start missing firing up past 20psi, you can slam the gap down on the freshies, and make your one clean 400whp dyno queen pass. hahaha
Show the party girl a good time, -----it....run a train on that bitch.

Re: HMT NE DYNO DAY!!!!!
Very important question on the guy running the GM8, which wastegate is he using? I don't expect/at least I hope he isn't using the stock internal wastegate and planning on much consistancy past mediocre boost. He has the GM8 which has the wastegate flapper as part of the exhaust elbow assembly and the wastegate actuator itself sucks ***. If he ditched the actuator then this won't be a problem, I'm sure he's been out testing it right? If he hasn't and isn't getting the consistancy that he wants, a simple, cheap, hack, ghetto solution is to drill a couple small holes in the swing arm that the actuator rod attaches to. Use a small spring or two and attach them wherever you can in-line with the actutaor rod. If you can quickly find springs that are long enough, you can sometimes get lucky and find one that will attach from the swing arm to the plate on the compressor housing and still be taught without being pulled. You want to have the spring/springs taught but not TIGHT so that they act as extra tension when the weaksauce wastegate starts opening at a much lower psi than you plan on running through the rpm range. If you have one around, use an airbrush compressor so you can dial down to 0 psi and work in increments until you find which spring allows it to open the wastegate at what HIGHER PSI than the stock wastegate is weakening at. If you do it right, you can effectively make a wastegate that STARTS opening at 6~8 psi START opening at say 10, 12, 14, or higher ppsi giving you a wider range of spool before it opens fully and starts dumping boost pressure that you need to get good numbers or else people will laugh at you. There's nothing worse than a dyno session with a turbo thats good enough to get good numbers mated with a brokesauce wastegate that dumps any potential BEFORE you can start laying down good numbers. Hopefully I've reached you in time if he's having this sort of problem.
