Belt slip and squeal is a common fault of the stock Vortech belt setup. There's been a few attempts at 'kits' to fix it, some work, kind of. Some are temporary solutions. The best one requires a lot of work to install and forces you to literally grind the timing cover down. 
So with the help of a friend who got my brain going in another direction on this, I came up with a variable tensioner solution, to maintain proper tension regardless of belt stretch or alternator/supercharger load.

I've got feeler threads out to see if this will work to sell as a kit, might be some help with race entry fees this season. might not. Either way, I'm thrilled that I have got the problem fixed so far. We will see what it does at high boost but I think the cold-start up squeal is gone.
The other great thing is I can change the belt without rolling under the car. I NEVER have to touch the POS stock tensioner again (they're just like the maxima ones that like to break, etc.) Just a 3/8" ratchet to quick change if I ever need to change the belt

What a day!!!
Taking a short break for a quick update. Car is tuned!!! She's a beast!! Big thanks to Sasha @ Onpoint Dyno for handling the Dyno Tune for me, great work man!
He had it up over 400 whp and 380 wtq, but wisely pulled the torque back and power followed a bit. End result is a very smooth 393 WHP and a nice flat torque curve that is hanging around 340 WTQ.
Peak boost was a pinch over 12 PSI, The usable bit of it peaked around 10-11 PSI though. Just perfect!

OMG, it's a freaking ban-saw! 
I can only imagine the shock on someone's face in the car beside you as you launch from speed on the highway.
In consideration of the little one you have at home, now might be a good time to add some supplemental life insurance. Just don't tell the Sales Agent about your G.

Overall, the car is a heck of a sleeper. Cruising around or parked at a light, stock exhaust, it's just another family sedan. So when I press the right-most pedal down, I get some looks of surprise. P.E.R.F.E.C.T.

I've had a few 'tuners' roll up next to me at a highway cruise (no noise really), and just glance over non-chalantly and look away, then I throttle up a little and they're looking all around for a second for the boosted car, it takes them a minute to even realize it was my car.
I love that, sooooo much.
Also, this is such a weird problem to have, the power thing. We normally chase every little HP with mods. I am literally doing mods now to REDUCE my power output because it's already way too much.
Looks like putting the dual exhaust with cattman 2.5" mufflers will definitely have to wait.
I think your next goal should be a new paint job.
And the bigger picture: a new house with a 2-car (three car?) garage.
^lol whaaat?
And I've got a list of little items to repair before anything else happens. As well as pending modifications like the trunk (which the body guy has been taking forever with) and painting the side skirts and front bumper cover.
Then he will be doing the hood, I'm having the 2 lines shaved down flat and obviously repainted.
I've almost certainly decided on IPL Gunmetal for color though. But with the way my mind changes, and the long wait until it ever happens, who knows.

BTW, it's called Graphite Shadow, not IPL Gunmetal. New in 2012 for all G's, not just the IPL.
Srsly, dude

Rochester what do you do about water spots?i have seriously hard water and no matter what i have tried the spots just keep showing up i dont want to damage the paint by rubbing them away when the car is dry
- The car is parked in a garage when home.
- I keep the painted surface clayed and waxed.
- When I wash the car, I chamois dry it either in the shade or back in the garage.
VERY few VQs pop using blowers, now turbos are a different story boost spikes&continuous over boosting is usually what kills them. With an S/C that those conditions are impossible. You can have just an ok tune and the motor will last for years with no issues.
Thanks dude!!
If I posted that, no one would have a clue what I was talking about. But I didn't know it was offered on all G's, thanks for the info! Ever since seeing it on a local IPL at a car meet I've basically fallen in love with it.
The torque bends the VQ rods. That's the weak link. The consensus seems to be that once you go over about 380 TQ you are really rolling the dice hard.
However, there's been more than a few VQ35DE's bend rods with 360 WTQ. There have actually been 2 fairly local that have done it around 360 WTQ.
Considering the Dynapack reads low (what I dyno'd on) compared to conventional dynos, and the fact that those cars that are bending rods at 360-380+ WTQ are just street-driving, I am really rolling the dice with even 340 WTQ. Because I'm going to race this car on weekends, and that's a completely different environment than anyone is going to do on the streets.
Either way, I hope that you're right and she just keeps going and going
The reason turbo cars are more likely to bend rods is simply because they make crazy *** torque (over 400 when de-tuned) and it's basically a flat line. I can't imagine there are too many non-built VQ35DE's running around with turbo's. The FWD versions don't produce as much power from them, so maybe a few of them rolling around un-bent.

Just fine.

When you bend the rods...it just means upgrade time! DE's are getting cheaper by the day, just upgrade the rods, Oil pump, and HR head gaskets and have some fun!
Love what you are doing, car looks ****ing fantastic!

When I do build this motor (IF I ever do), the only 'big money' on 'major name brand' stuff will be the connecting rods. There's no reason to spend copious amounts of money on anything else. There's no reason to build the heads, there's really not much to improve on signifigantly other than the rods.
Fuel system + Clutch + better rods + boost = reliable, big power. That's really all it takes on this thing, despite how much everyone likes to spend, it's simply not necessary.
