It is usually a ~20 whp difference (I have seen as little as 12 whp from HFC's over test pipes). I don't have any dyno sheets from someone running long tube headers with the kit. That might end up being a wash because of how much more efficient long tubes can be. I don't have a lot of experience with the long tubes on a VQ37 (stupid CARB) so I can't say for sure what the results would be.

"It was a stock kit with GTR injectors tuned at stillen. I got it tuned there for reliability, The engine had 29,000 miles on it, got 3,000 out of the supercharger."

I did see that. Hoping we can get more info so we can figure out what happened. I've never seen a motor get blown from standard kit with no crazy mods. Only thing different on that car are the GTR 570cc injectors (I think that's right) VS the normal 600cc injectors. There are always other potential causes for lean conditions (not saying any of these actually happened). Someone could have put non 91 octane gas in which could cause that issue, but the knock sensors should have pulled timing pretty fast, Could have been a vacuum leak post MAF + pre blower, etc.
I have never seen a Rod Thrown from lean conditions. Usually it has to do with oiling or over revving. I am trying to work with him to help figure out what happened.
