Here's a little video we shot on the dyno last week. :D

Still on the stock exhaust for now, so that explains the mystery of zero exhaust noise.

Right click, save target as please...

G8 GT Twin Turbo on Dyno (http://www.intense-racing.com/movies/G8GTTTDyno.wmv)

You can hear me take it up into fourth gear, then put it on the floor around the 25 second mark. That's 140 MPH in fourth gear when I let off the gas. And there are still two more gears. :driving:

How much psi were you guys running for the 473rwhp???

~ 6.5 to 7.0 psi with stock exhaust.

Yummeh.

wow. Now how complicated and how expensive is it to do this?

hmm not bad, the dyno chart in the video was a little blurry lol it might just be me

Was that still with the stock injectors or did you change them? The exhaust should free it up enough to touch 500 or damn close with just 7 psi. i already have the credit card im using to purchase the kit but i have to get the car first which is sadly in about 10 months,in the process of saving a down payment.

man the sound when you hit it and you could hear those turbos spooling gave me the chills !!!!

Wow from Ohio too. I love it! Now I just need a G8......

I'm assuming drivability is similar to stock?

God i love that kit. That right there is my ultimate plan.

How is drivability on this car? Do you have more room to play?

How much is this kit? I am in the market for the least expensive route too good HP but still drivable. Not looking for 6-700hp. Would like to keep stock exhaust as the car in the video. Would like to keep stock fuel injectors and anything else possible. The least expensive kit I found was $6995. Does anyone know of anything cheaper?

it would be great to get it if they have it on payments lol

The car drives and sounds totally stock. Power comes on very smooth. Best way I know how to describe it is the car feels like it has the smooth torque curve of a 500+ plus cubic inch motor under boost.

Thats so sweet. THats the route im going with my G8..I wont even bother doing any serious exhaust work, except maybe a Borla catback that sounds tastefull. I dont want a loud obnoxious car..I want to be able to cruise on trips and not deal with a drone or yell over an exhaust tone..

Then when you need the power, **** 400+ RWHP is enough for me...Dont need the xtra HP from headers/Xpipe etc..

We've learned a lot tuning our twin turbo G8 and we now have the ability to share that tuning knowledge with the community. We've recently announced our mail order ECM Programming for the G8 (http://www.g8board.com/forums/showthread.php?p=65412#post65412) and we can tune your G8 locally as well.

Scott ain't kiddin! That car is awesom!!
