Basic low boost build: Noob does it all wrong.

If I mount my potato cannon to a turbo car, would that count? I still have the 12ft one I made back in high school.
No M45 yet, sadly. I will be retaining the stock airbox though. Turns out I will need to do a bit more work than expected, so I have unburried the mill. Pics of that later.
2.5" PVC has an OD of 2.875. A good compromise between 3" and the ID of the stock crossover tube (~2.7ish).

Spiffy! I am curious how long it will last. I will order up some aluminum at some point.
If this were pressurized I would have used something different (PVC will handle lots of pressure if you keep it cool, have to derate it to 20% by 145* though!).
Speaking of pressures and heats. I need to start researching intercoolers. The M45 makes a crap ton of heat from what I have heard, so I am thinking an e-bay roulette one isn't a great idea. I know the ones with the turbulators are fine, but finding one when the product descriptions are so horrid is unlikely. Also worried about too much pressure drop, though at sub 10PSI probably not flowing enough for it to be a problem. I hear good things about the vibrant one on amazon?
Would like to keep it under $100, but if there are none that will do the job well for that I can push out to $200 for the intercooler. It isn't like they go bad over time.

Don't worry about pressure drop at 10psi. There is nothing better than the ebay intercooler below $100. I think the seller we all bought from is still selling the intercoolers. It's stickied somewhere.

Any reason not to bump up from the 5.5" tall one to the 7.5" tall one?

Went ahead and ordered this one. Looks like it is the same one you guys are all running. I will be curious to see if it can keep up with the supercharger.

Track night #2 was a success, other than almost overheating my motor. Caught the gauge going up at the end of the first session, popped the heat and fans on coming into the pits since it was still going up even after slowing down. It got up to 241f according too the logs and had been running about 235 for the last lap or two of the session when I checked the logs.
Turns out my car reaaaaaly does not like having a front license plate. Temps dropped down to 215 or so next session out, max of 219. Not great, but a lot better. Need to get around to doing the rerout.
Otherwise everything went well. If I really pushed it I could grease out the RE-71Rs in three laps, to the surprise of noone.
The PVC pipe didn't melt either. And, much to my surprise, my car uses no oil at track days. About 2800 miles on this change and the two track nights (about 2 hours total on track) and it is only down about 1/4 qt. Which is where it normally is at this point.

I put the under tray on for this event since I finnaly got one.
220f is definetly hotter than I would like. Could it be because I have an AC system installed.(though off). May just have bugs and tar clogging up the condencer, I might try cleaning it out and stratening the fins.

Looking at the logs again, it looks like the second session was mostly between 200 and 215. With one peak up to 219 at the end of the long straight after I slowed down. Third session stayed sub 212. I know my AC condencer is banged up, so I would place money on it being that. Next track day likely won't be until august or september though so I won't know until then.
