Well Jason up here in NH got his motor back together and running yesterday.

See post http://208.109.104.11/forum/showthread.php?t=5972

It hasnt left the garage yet but (runs) and sounds pretty good. Hes trying to figure out where to start with:

1. Waste gate settings for the turbo's gt42 & 55:D
2. Tuning.. but I think Tony is coming up from Conn this weekend to play with it.

DONE !!!

Jay left a while ago...........after our last WOT test session we were heading back to load it up on the car hauler and up ahead we see "THA MAN" with the red's and blue's spinning, sitting on the side of the road.............:rofl:

We made a quick turn on a side road about 1/2 mile before his cruiser and went around him back to the car hauler.

The truck Runs.................:eek:.............the speedo climbs incredibly fast to 100++ and smooth power and boost.................:D

We couldn't get enough real estate to stretch the legs on her, but she moves for sure, my buddy road along and he actually said he was a little scared............:baby:

Jay is going to get some driving time on the truck now as it is dialed in on the street and hopefully some track and dyno numbers soon.

We are hoping the Allison holds up, it was having some fits earlier but we think we got it figured out.

;)

Hows the spoolup initial & secondary?

The primary lights excellent, very quick to come up on boost, the secondary feels like a huge N20 hit when it lites, but comes on a lot smoother...............;)

I have been in the passenger seat of many fast trucks including Nasty-Girl and this truck is really, really fast !!!!

I hope Jay can geta video of how fast the speedo climbs and how the twins sound when they light.......:D

Dyno

The purpose of the dyno was to get the turbo's dialed in.
We were playing with the waste gates and boost pressure, with that 760 hp we were at 55psi main and only seeing 20-25 psi out of the gt55, so we have a ways to go considering the sweet spot for the gt55 is 40psi.
I can't wait to see what it will do on the next two tunes with alot more fuel and more boost:):):):):):)

The dyno was to get the waste gates adjusted. that 760 # was at 55psi main, and only 20-25 psi out of the gt55. so when we hit the sweet spot of 40 psi and the next bigger tune, hold on it should ge good:):):):)
