Jrod,
Love the second video because you tee'd it up perfectly. Great sounding and fast ride. I am sure you will see several people post wanting photo's since you only have 6 posts... I would recommend getting those in order. Congrats on a great car and win!!! Any HP figures? What has been done to the beast? Cheers and welcome, Bryan

Great results. How have you handled the high boost.
500 hp at 0.7 sounds like it breaths really good.

JROD, specs of the build, please...I am considering variable boost controller so I can turn up the boost at higher speeds. Running 500WHP at .8Bar, but in 3rd -5th could go higher. Nice work and great video!!
