Who in the world would put a 6262 turbo on a VHR motor? That is a 4 cylinder motor at best...You can see that at 6,750rpm the small turbine wheel and turbine housing become a choking point.
Now if you compare this graph below, to a your TT graph, and add the 10% difference in dyno readings DJ vs DP (that looks like a Dynapac hub dyno, correct me if I am wrong), you are basically on par when it comes to performance:
Journal bearing 6266 T4 1.0 a/r (BB will gain about 200rpm in spool as well):
So if you are putting (comparing a properly set-up ST to TT), the two cars side-by side at the track or a roll race I think the phrase "slaughter" is a bit comical...no?
I am not trying to stir things up here by any stretch...I have a great deal of respect for Tony and the boys at F.I. They provide the community with a tremendously good products, which they stand behind and support. There is absolutely nothing negative I can ever say about that company, the products they offer, or the people behind it. I have had several conversations (phone) with Tony, and he is truly a stand up guy. I have directed many customers that way for TT kits, since some customers are under the impression that I have TT kits as well (confusion between TS and TT).
