.43 A/R or the .68 A/R turbine housing...

[nightracer91]

Okay, I finally decided on a turbo set-up on my fully-built Talon. I am going with a externally gated 50-Tirm from PTE. While exploring it, I noticed it gave an option for two different A/R ration turbine housings. Know, I know the lesser the A/R, the faster the spool but more back pressure on the top end (street driving), and the higher the A/R, the more the lag but better flow on the top end (track). The two options at hand is .43 A/R and .68 A/R. THe .43 is much like the factory 14B and the .68 close to a big 16G. Is the difference between these that significant? I plan on an almost daily street car with some track. Is the .43 going to be too restrictive for the track? Is the .68 going to be too laggy for the street. Anyone with a similar set-up, your responses are the most valuable!! What would be the more efficient choice?

Go with the 0.63 A/R.

its actually .48 and .63 to correct ya....

Id go with the .63 on the 50 trim, it will still spool before 4k which will be very streetable, and give you the top end power on the freeway or for the occasional track visit.

Awesome! That's what I wanted to hear... Yea I noticed the numbers after I submitted it then forgot to change them

BTW... I posted it on the newbie forums, then noticed my newfound "proven member" status so I decided to post it in a more suitable spot.
