The key for me is slowing the spooling of the turbo down, I have a 07 st with the GT2860 on my street car, it work nice as a dally driver the power comes in early around 2700rpm, however I have taken it on the track to see how it is, and the power comes to quickly coming out of the corner tending the make the car understeer or Push for the NASCAR fans. My street car doesn’t have near the grip as the track car and has a lot more understeer built into it, but the coroner speed in the race car is much higher and I’m in the gas much sooner. So I want the power to come in a bit slower and not hit like a sledge hammer.
Right now I’m leaning to the GTX2863 with a larger .82 a/r. Still need to get my motor back so I have a bit more time.
My rides a 2002 SVT track car, & Boosted 2007 ST with the SAP.
The helmet has a special meaning for many drivers. How important is it to you? - It protects my head.
Do you have any special rituals when the helmet is concerned like many have? - I wipe it so that I can see better.
