Thank you Freudie1: I have contacted my Dyno guy Dan Thayer. I will set up an appointment with him to take my plenum in to him. I will also buy an extra set of cam gears for him to slot should the need arise. I'll be doing this all at once in one visit so I don't waste his time. If there is anything else you think I should bring to his attention please let me know. I'll post here my revised and updated build sheet so if you have a chance maybe you can tell if I'm missing anything. I have an order in with Gowanda Harley Davidson for the last two tools that I don't already have that the manual requires for the build: Tappet Compression Tools and Locking Pin.
Search the forums, you don't need those (or you can make homemade versions).
I know Scott Fitzgerald was selling a compression tool he made in his machine shop at one point as well.
There is a mountain of information you need to read up on especially if you have some time (and it sounds like you do).
I'd grab a copy of Corky Bell's book on forced induction to start bedtime reading. I'd also recommend reading some "old" forums in regards to cars that were factory boosted and are very popular: DSMs, Grand Nationals (REALLY good info)....
Read up on detonation, knock, pre-ignition. Read about what each one is, what it does, how to avoid it. FYI: If someone tells you it's not an issue with a Revo...ignore them. Laws of physics don't change regardless of the application.
Read up on engine control options for this bike. I'm very against aftermarket gadgets/tuners/ecus for this platform. Some have had some success going that route. What you are planning MAY require aftermarket due to the high levels of boost (relative to the Revo that is....) you are planning on using. Curious what boost level you will see with that big a Rotrex on this engine. I have no experience with the larger Rotrex headunits. Has Richard shared a compressor map (or have you downloaded one from the tech portal from Rotrex)? You can figure out boost levels from that (and the pulley size on the headunit).
I can't caution you enough to take this slow. It's incredibly easy to end up with two big ash trays formerly known as pistons (and that's the best outcome, worst is you have extra "ventilation" holes in your block!).
Several of us on this forum have discussed (and implemented) alternative boost control methods for the Rotrex superchargers by the way. I'm staring at a solution right now however I can't remember the name/vendor, RON: What is the valve called again? <--If you really want to maximize the potential of your blower I would do the following:
Put the smallest pulley on your headunit that won't cause it to spin faster than specified (read map and docs from Rotrex). In conjunction use an electronic boost control tied to an external dump style wastegate. If you design it right you could even tie into what gear the bike is in (you would have to read the J1850 databus to get this data, read get friendly with a custom electronics guy/car hacker) and then feed that into the boost controller so that you could have boost levels different by gear! I run such a setup on my drag car as it helps from blowing tires off for the first half of the track.
Intercooler: Topic unto itself. BIG fan of water to air, especially for drag racing. You can build some stupidly complex and compact i/c setups this way. MAKE sure whatever IAT sensor you implement is "fast" reacting (pro tip: The stock IAT sensor is slow as it wasn't designed for fast temp swings such as what your intake charge will do when boosted...). At a minimum you want (need!?) to log accurate IAT's so that you can determine IF you need an I/C (spoiler alert: you do) and secondarily how well your i/c is working.
Your two biggest enemies: Knock and fuel (by the way WHAT injectors are you running in this setup?). I see your list states "650CC" for the size, but what model/type? I run the IWP-189's from a Ducati (Richard sells those or at least he did....btw very hard to find actual MM injectors as they are counterfeited to hell) but <=12 PSI on my setup.
Read up on my fuel pump rewire/circuit thread as well. You WILL have issues if you don't.
Enough of my ranting, go start reading.
