We found a source and ordered 5 pre-bent intercoolers....they aren't here yet so we will see how they come out. Sizing on the core will be 320Lx220Wx50T and we will be using them on a '06 Turbo GSXR750, '08 Turbo R6, and a '08 Turbo Busa....I will give feedback and let you know how they work out....might be a nice source to locate these from here on out.
Hope to hear more about these cores as soon as you have an update. I have a late '99 gen 1 busa and would be interested as to how well they may fit this model. Although I can see that you are testing the core in an '08 turbo busa... surely if it goes well in the '08 then it may not pose too many problems in my '99...hmmm just have to wait and see!
Having a nice source for these cores would certainly be great.
