plenty of threads on this. obviously the larger inlet would allow more air flow so that translate to more power. the larger compressor also helps the bucking high gear/low rpm issue the 64 has.

Actually the 80mm opening is not an inlet it is just a surge port.
So instead of having just the 64mm compressor inlet, this additional
surge port around the inlet greatly reduces the air turbulence
and overall surge conditions which can occur with higher lbs per min.
airflow turbochargers. But this does not increase overall HP and TQ values,
it just allows for a wider and yet more efficent usable power range.

Well maybe it was just my car but I gained hp on the top end. 15-30whp from 7-8k. The peak #'s stayed around the same but the topend was greatly increased.
Right after I installed the 80mm housing my original tune leaned out, So I knew it was flowing more air.
I was running 1psi more but it was 96deg. compared to 77deg.
I will post more info later....I am at work right now.

i really DONT think the 80mm will give you more hp seriously lol why would they even offer the 64mm still. I heard read/told its strictly for surging purpose. not for that and you will gain more power. im pretty sure roger it was due to you retuning and turning up boost.

Based on what I have seen from various dyno charts the 80mm cover hurts initial spool up and does not seem to have any noticeable gains in the upper rpm range. If it helps surging that's good but I experience no surging at all with my 64mm cover.

The 80mm housing did seem to hurt initial spoolup but made up for it on the top end. The only thing that was changed from the orig. tune was a/f , timing was left the same. We had to add more fuel because the new housing made it run lean.

rodgerv - was the only swap the turbo when you experienced these gains?
intake pipe / air filter remained the same?
if so, thats a pretty big spread between turbo to turbo....
generally anti surge ported turbos loose a bit of flow compared to a non-surge ported housing, but you also loose the surge condition....so you give to get.
Consider yourself lucky, you got the best of both worlds!!

The orig. buyer of the turbo bought it in Nov.
