Here are some dyno graphs for those of you who like data.

One graph shows the big differences in stock turbos. 2003 vs 2007
Then shows how much quicker a 2007 turbo spools just by adding the 11 blade turbine wheel.

Keep in mind a 59mm 2003 turbo is bigger than 56mm 2007, hence why the 2003 still makes a little more power than the 56mm 2007 turbo with the 11 blade turbine wheel.



But here are the results testing different wheels in the KC s1 jetfire.

 

Wow! Incredible results! Will these be available for diy install? Would love to switch out the 13 for the 11 blade in my 1.5.

 

DIY options will come later. But as of now the 11 blade won't work in an s1.5 or s2. We are working on options.

 

We thank you for keeping the 6.0 R&D alive !!

 

Curious, are all those runs on the same truck? If so, what other mods are done to it? Those are great power numbers. Thank you for posting.
