Opening week at the Plex the hottest my engine got was 210, steveja pulled his gotech off at 280 when I was temping mine

I also put an O.S. P3 in mine after break-in, seems to smooth out the idle compared to the cold plug that comes with the GRP.

Matt, have ya had the chance to compare the GRP to another motor - power wise? I'm curious to see how it matches against my EB Modded V Spec. I'll be starting break in on my GRP tomorrow when the engine mounts come in.

And I love that sig. Ironically, I got yelled at on the driver stand this past Sunday when I was lapping a guy in the main for the 4th time. He yelled at ME to get out of the way!
