Assuming you had either A/R option for your application (in my case gt35r with .63 t3 or t4 housing) which is better? I keep reading that T4 is more efficient with some scavenging effect created by the divided housing, this supposedly means quicker spool. I have an automatic car so response is important for daily driving. I am currently having a manifold built by straight line with a T3 flange and I am considering with some input from you guys weather or not I should change the manifold to T4. The change won't affect cost of the turbo or manifold that I can see right now.
Instead of creating another thread about Compressor housings I'd like to hear your takes on surge ported housings also. I am leaning towards a surge ported S housing unless there are others I should consider, but, my builder feels that without SP's the turbo will be much more efficient. My argument is that the car is a pump gas car only, no plans of race gas, ever. So not sure if that effects me but I will usually be in the lower end of the compressors pressure range and I think that would help keep me safe.
Compression is 9:1, I'm thinking I will be limited to 18-24psi with 92 here. If there is any information about my application left out I will try and help fill in the blanks. Thanks guys.....
