its pointless to even try to guess the #'* without about a +\-5 difference, because alot can change almost instantaneously. You might get KR and have less, or heat might take away a few, even dyno numbers arnt the most accurate thing in the world. You wont get the same numbers every time.

Seat of the pants is much better, and really the only one that matters

Slap a sticker on there and you will have 25000 hp. Imagine if you would add those little LED windshield spray lights on your hood? Yowzers!!!!! Look out Nascar!!

Just get a window marker and you can write how fast it is.

Sorry Martin, missed this one

My Aurora 4.0 has a stock 180 T-stat...and a very pretty PLASTIC upper intake manifold (without the 3800 issues)

And I forgot to place my guess. I'd say you are in GXP territory now HP and torque-wise.
Is there room for a FWI with a header wrap wrapped tubing to the TB?
I'd bet that would help tremendously.
How about light-weight pulleys? Anyone do PCM'* for the N*'*?
These three mods on top of what you have I bet would make helluva 4000 lb beast. Possibly put you in the mid-high 13'*.

I was hopin for GXP type territory, the 80mm TB should put me over the top.

I doubt there is room for a FWI, never seen an Aurora with it, I may figure out something to do with Taylors intake pipe...we'll see.

Hoping Intense does something with the Nortstar, but a PCM is something I dont need, esp with stock Autobahn. Pulleys...well she had 2 serpentine belts...so ya never know :P

I would like mid 14'*

Are there no companies that supply aftermarket performance parts for Northstars? I would figure if there are parts for most other N* engines, parts for the 4.0 would be easy enough to produce

DP and RSM offer good stuff, but I have most of it, or am planning on it

I have the better brakes, I have a cat back exhaust now, I am getting the TB, the turbo is WAY to much money. No chip for the OBD2 Aurora, I will be getting strut bars and sway bars etc next summer

Not much else for it.
