Highest Stock K04 Kappa record

Just curious, I'm wondering what is the current record for the highest WHP on a dyno with the stock turbo. No Nitrous of course because thats cheating haha. Anyways, I'd like to know because I'm going to dyno on the stock turbo I believe Saturday and would like to compare. I like to think my sky pulls hard. It def feels like it pulls harder than my fully bolter 847 cobalt ss turbo did.

Anyways please let me know!

You asked the same question on the BB and someone answered 307WHP.
I do not know how anyone can obtain that number on a stock turbo with a tune. The highest I have ever seen was 298WHP.
We know changing the charge tubes (IC pipes) does not yield any HP improvement.
Also a new IC will yield very small HP increase if any.
Is all in the tune and there is not a lot of room and be safe to get to those numbers.
E47 or E85 is also cheating.

Stock turbo on an LS3?

 Did not see it for myself but, I have a contact actually a couple of contacts that worked on the factory GM race team that ran cobalt ss turbo in grand am. They sais they had a 425hp tune that GM did for the program. I was offered this tune, didn't take it. Was afraid it might break stuff. They are believable people, said the cobalt just left the mustang GT out of the chicane at Daytona. I was also told by Don Knowles the T2 GXP he raced had this kind of power, along with $8000 dampers.  Anyone seen results like this ???    I would assume at flywheel HP
