anyone.... .89 exhaust sounds huge to me and its a really small turbo but i dont know much about turbo sizing

 

or is the A/R a ratio of the intake and the exhaust sides

 

hmm no help?

It is complicated enough that I don't remember what it is off hand. I really should remember that kind of stuff. But .89 A/R is damn big, and wouldn't come close to my car. lol</TD></TR></TABLE>

A/R MEANS NOTHING unless you know what wheel it is. Entirely and completely useless information.

A T28 like this usually has a T3 compressor wheel and a T25 turbine wheel. T25s are not very big wheels comparatively, so this could be a good turbo for like 160-300 whp roughly. All the t25 wheels I have seen have been a nightmare of a restriction. I would use at least a t3 wheel of some sort. But there may be big t25 wheels out there im not sure, or interested.

to the original poster, what makes you think its a T3 turbine inlet flange? most t28s (if thats what you have there) have a t25 flange, which looks like a mini T3 flange.

I know this now, I just wasn't 100 percent at the time. I have heard a billion things about it. I know it has a lot to do about the wheel. And I gave some info.

 

because it is bolted up to a SSAC manifold. are the bolt patterns the same on a t25 flange

 

t25/t28


dsm 14b/t25



t3

 

some dude around here is using a t3/t25 set up...weirdest combo ever...he made around 180 hp at 8 psi on a single cam...

 

so it must be a t3 flange. those specifications were all there was on the ebay auction he bought it off of so this is why i ask.

Commonly know as a T28

 

so it would be a t28 or what? if we got a serial number off of it would garrett be able to tell the model?
