So I finally got to install my LS6 intake on the TA and I also got a chance to race it against my old GTP. We did a couple of street runs from dig to 70mph and they were dead even. We will try again probably in a week or two at the 1/4 mile, maybe I'll beat the GTP there since the TA has more top end power.
The GTP mods are the ones in my sig except it had a 3.4 puelly, AL104s and stock tstat. The TA mods are the ones on my sig too.
We'll get videos when we do the 1/4 mile and I'll post them here then, but definitely supercharged/trubo cars have the advantage here at 5000ft. My next ride will certainly be turbo.
