Great news....the reason for the 1.30 AR was we were overboosting with the .96 housing that was ordered originally and we where flat on the upper rpm, the 1.30's made all the differance in the world. It took care of the overboost by bleeding some air and it also helped with the restriction too, the car woke up and was totally like driving a new car with way more HP.
So, will we hurt ourselves here by running the bigger AR or should we drop it down? Or just leave it alone?
Paul Traci's car went with HP66's and they had to re-cam to help spool the turbos faster as they weren't spooling until 4k, but he also doesn't have the GT-K 650's either, and what I'm hearing is the way the compressor is ported on the GT-K 650's and the new wheels this shouldn't pose the isssues Paul is having...yes/no?????
