Well...
I see that other people are enjoing the boost game.<img src=icon_smile_evil.gif border=0 align=middle>
My controller came with the metal ball in it. I was trying to get the ceramic one for testing but I guess your research has shut down my eagerness to try the Ceramic ball upgrade.
The problem with our turbo is the quick spool up times. I thought that with the ceramic ball it would respond faster than the metal one.
Remember keep it on the safe side.
Now we need to fix the excess pressure exaust in the system.
The factory BOV is too small for the high volume now generated by the higher presures of the turbo. we need to find a BOV installation procedure for the PT!
I talked to Exhaust Depot and he is already working this issue. He is tinkering with an idea and should come out with something shortly.
There are some ideas on the forum but none has gotten out of the Idea phase.
After I saw a Turbo Explode in another car at the track, he was boosting 27 PSI, and then saw another car with a huge BOV installed working. It made me think that it is time now to go to the BOV Phase.
This car had an HKS BOV installed and when he let go of the gas, besides the huge hissing sound, you would hear the turbo spooling down with no strange noises. it sounded like an aircraft slowing down. Cool! <img src=icon_smile_big.gif border=0 align=middle>
