Any experience with small trim (48) GT2871?
#13
Just like all of you other obsessive fools, I'm always thinking "what if I tweak this or that". Also, my thinking about the wee 2871 is not just for myself, but for other fools considering the 2871.
But yes, I'll see if I can get back my missing 200 RPM or so of spool. If I then go "ohmygod this is so much better", then I'll stick to my wee 2560. If I go "meh", then I'm a gonna be bigger turbo dreamin'.

Depends on your definition of "street car" but Id have to agree (even though I'm not sure if you're sarcastic or not lol)
On my "street car" the only time I opened it up was on the freeway or a freeway onramp. I had plenty of lowend and response down low to not hate life and get decent mileage. When I wanted to haul *** it was just a downshift away.
In Jasons case though, (going off what he's posted in previous threads) he likes auto-x type driving, twisties, etc....So response and lowend grunt is thuper duper important to him, and I think I understand what he's going for here.
Do you have e85 there Jason? You're in the bay right? Cause with e85 you would not only get a little better spool, but be able to seriously push that little snail of yours to its limits.

i just dont see the point of the 71mm wheel over the 60mm wheel when we talking about gaining only 5 more lb/min capacity and going from a short fat efficiency map to a thin tall one...meaning it's a better turbo for higher boost but lower flow rates.

Yeah. 35 lb/min vs. 40
On a 60mm wheel vs. 71mm
I guess I don\'t see what the gain would be. The shorter fatter island of the 60mm lends itself to lower boost and higher flowrates. The 71mm is tall and skinny so its made for high boost levels but not a lot of flow considering.
