I have a t-3, how do I tell what size it is?
Thanks,
Chris
Read the numbers printed on the compressor housing and inside the turbine inlet.
Ok, here is what I have.On the Red Reman tag there is an S/N GHM05699 and a P/N 409174-9054 Then on the hot side down by where it bolts to the manifold it says AR 48

Is this better then my IHI?

Thanks,
Chris
All stock Ford T3 were 60 AR on the compressor side and either .48 or .63 on the hot side.

Is it better than your IHI?: it will push more air than the IHI at a given psi level and it will allow you to run a little more psi. I don't know if that is better or not [Image: biggrin.gif]
Your IHI is way better. You don't need to go any higher than 4500rpm anyway. Just send me the T3 and I'll dispose of it for you. [Image: wink.gif]
