Yes:

There is more power on the table, we ran out of fuel with Shane's car and didn't have time before he left for Vegas to install a larger 044 fuel pump and regulator.

The intercooler for the Stage 3 is a work of art. Hand made by Todd with the 1,000hp twin turbo (the prototype is on my car).

THank you for the link! (Doh, hate it when I miss something relevant!)

Wow, those are impressive results. 10 psi is getting sorta serious, and the Stage III dyno numbers are as well. So I'll read on about streetability.

And I'm really surprised there aren't issues with vac hoses and rubber boots blowing off-though I see the boots are now silicone with t-bolts, but that shows that I need to put some more work into figuring out the intake pulse v. cylinder vac signals. Tough thread- geez I dig garnet & ruby cars...

But back in the real world...its got to cost about what my car did.

17psi on my car (16V) and 30 in Todd's car, no issues with vacuum lines.

Took a bit more significant test drive and all I can say is wholly crap!
The car pulls like you wouldn't believe. You get a little warning. When the SC starts to whurr up...you know its coming. It pulls until the shift and then pulls harder.....crazy.
The car never got above the first line on the coolant temp once I had the fans going in the right direction
Looking forward to cars and coffee this weekend

Sounds like the rest of your install went pretty well.

Most of my issues were user error or simply not knowing the correct way to do things. As many know...there seems to be the right way to assemble/disassemble things and the hard way. I could honestly do this install in half the time now that I have been thru it.

I had the whole weekend with decent weather and got to put a whole tank of gas thru her. All I can say is wow. The car was really great before. I loved the power and responsiveness once I got the transmission fixed. That being said, the supercharger is FRICKIN AMAZING! The power has exceeded my expectations. The neatest thing about it is the car is 100% drivable. No surges, not weird lunges, no funky idle. You hear the faint sound of a whurr under the hood which gets people raising their eyebrows as you drive by.
I was able to get out on a country road far from traffic. An M3 (2012 or newer) turned onto the road in front of me. I caught up and began to pass him. He immediately started to accelerate. So of course I stomped on it. The car pulled right by him and continued to pull away. Got about 4 car lengths ahead and slowed down...he zoomed by me and we eventually got to a light. He rolled down his window and yelled "WHAT THE F#!@ do you have in that car!?!?" He was smiling and so was I.
I have to admit I still haven't taken off from first gear. the car accelerates so fast out of second I can't imagine what it would do in first. I'm trying to spare my tires.
All n all I'm very pleased. Thanks Tim Murphy for all your help, and fielding my freaked out phone calls.

I've a feeling you just sold a few more SC kits!

I have a feeling there needs to be some go-pro action posted up, or else,

This....
