Default GOClubGP dyno day with the Shadow...

Our local chapter of ClubGP had a dyno day today, and just for sh*ts and giggles, I ran the Shadow that I picked up from Pinky a while back.
First off, let'* make a few things clear, here. The 12 valve SOHC 3.0 V6 is rated for 140hp at the crank, stock.
This particular example is out of tune, roughly eye-ball timed, and is leaking from various places.
Oh, and it has 250,000 miles on the motor...

That said...

125hp, 163ft-lbs!

We had a pool going as to what it would do. Rogue won with a guess of 128.
Guesses ran from Todd'* at the high end, to 99 at the low end, with one DNF entrant...
I was floored by the results, my guess was maybe a little over 100hp in that tune, and I never expected 163ft-lbs...
And just think, the car only weighs 2800lbs...

Damn!!!!!!!!!!!! That little sucker makes nice power.

(for those that don't know, the 3.0 makes 140 stock at the crank, and 125 to the wheels is impressive.) Quick little car too.

EDIT - Saw he made that point already.

I think we may have...it started a REALLY loud rattle today...
Fortunately, it was on the way home to meet Sean so we could pick up the Buick...

Not sure what it is yet. It could just be a dropped adjuster. Don't worry, I won't let the car die yet...
