I like that center console it looks like it belongs there. Was it hard to fab it up in there

 

[Lostnwalmart]

about time LOL

 

[AHall]

Console really made the interior look great. Also i'm not sure why I've never done a thread on this truck. Been working on it for over 5 years a little at a time. Multiple injectors, turbos, pumps, blah, blah.

 

[jamesl]

thanks

 

[AHall]

GT55 and don't have the filter number on hand.

What elevation?

 

[AHall]

No idea on DA. Dyno at ATS so around mile high at 90-95* i think. Also no fan on the intercooler which I thought was strange. Track was around 4500ft, 75* and high humidity.

 

[Lostnwalmart]

High humidity in grand junction? Was it like 20% LOL

With such a large primary I would think power would be up. I think 4500ft elevation explains some of the lack of.

 

[AHall]

You would think. Timing is at 17.5*, Weston's 5/16 large sac, 7mm 100cc, 180hp pump w/ barrels at half, ad200. 181/210. 25psi out of the primary that run.

Stock intercooler is holding up somehow. I"m sure the air is hot going into the engine. Looking into doing a w/a in between stages or injecting water into the comp wheel of the secondary. I think the biggest improvement will be going from a 1.18a/r housing to a 1.0 on the primary to get the boost to ~40psi.

Wouldn't shift into 3rd so had to let off the throttle to catch the next gear.

I think there is plenty left in the setup. Increase timing, cool the intake charge, turn up the fuel, verify fuel pressure, harder launch, etc.
