Mine went a 10.50
10.50's without caps or girdle?? For how long?
I would be more than happy with those times. NHRA is a biatch once you run 9's. I found that out the hard way with the SBC. Have any of you guys noticed that the te-45a is harder to spin by hand than the stock turbo?? Unless mine had alot of wear there is a definate difference between the two....Does that sound right? Yes, 11's on the stock setup with only 1.7 60 fts. It suprised the hell out of me too!!

So, it's harder to spin by hand 'cause it's a big shaft? How does the size of the shaft have anything to do with how it spins? It seems to me that big or small the shaft should be irrelevent on how the compressor wheel spins, but then again, what do I know? Thanks for the feedback from all. I can't wait to drive this thing with the new mods!!

I'm thinking (could be wrong here) that if you compare . and o there's more friction surface in o
but the reason you use o is because it's stronger, surge and flutter and whatnot is less likely to damage the bigger shaft/bearings. Also, I'm guessing that until you break in the turbo a little, it will be harder to spin than the stocker that you've been using. The wheel is also larger so it'll be harder to start spinning because of inertia. Once it's spinning though, it should be harder to stop.

I would have to take a look at the compressor maps to tell if not the turbo is efficient at that pressure. Axial type compressors like ours provide the most amount of compression within one or two stages (i.e. twin turbo) after that the efficiency goes down. You get the most amount of compression per stage but are limited to two stages. At that psi level I would have to say its just blowin hot air and the compressor blades are stalled out. Just random info.
