I'd be interested in seeing information on this aswell. I only know of "twicks69" or something like that tested a s374 vs. GT 4088. I'd really like for someone to test the bigger frame turbos out on a 4g63.

Yes, but I need to retest because my results where different from everyone else I have spoken to. So over the winter I will test again and if I get the same results release them.

In case you don't have access to the link forums, this was posted by Nathon Neimczyk, he is the owner of the 4g63 dragster:

Just because it's not posted on forums for all to dissect, doesn't mean it didn't happen. I have personally dyno'd, back to back, within 15 minutes of each other, on the same car, on the same dyno, a GT4202R with an S400SX 74mm turbo. The S400SX picked up several hundred RPM's in spool and 50 HP peak. We repeated the pulls on each to verify the results. We then went to the track and picked up significantly at lower boost on the S400SX and haven't looked back since. We spent a LOT of money to make this test happen and to push our car further to post up for everyone to pick it apart and try to say how it doesn't apply to their 16G car because we didn't do the test below 30 PSI and weren't on pump gas. BW knows how to build a great turbo that makes awesome power.

It has also been noted by several people that although the BW will outperform, it will not outlast the Garrett counterpart.

I have no personal information to add to the discussion but I thought I would share what others have mentioned.

What results did you happen to get the 1st time? I'm just curious see what you observed.
