You can try to keep up but we never stop moving forward. We want to keep pushing the limits further with this world record ZR1 and we have so much more in this setup. Thank you for our C127 and the supporting components. This was a tedious and extensive install but we got it done. It turned out great with some nice carbon wrap touches to tie it together.

What an emotional day for me to hear this thing again. It's everything I wanted with the fender exit exhaust. Those turbskis sound amazing. We have tons of cleanup etc to do on this car probably a few months realistically but she's freaking alive. 4 years this brand new solid roller beast has been just sitting. Time can get away from you for sure. Never again will I let this car sit like this again. Last time this car made 1600/1400@26 with Chinese turbos and stock manifolds 💪. We are fire ringed and ready for big boy boost. OG still doing its thing. Lots to do but big moment.

Another JHP custom spec'd cam and another homerun. 93 Octane as well no E85 hero here. Hopefully Matt enjoys his new setup and we appreciate him allowing us to further this build on his second round of mods. Check out those huge gains over his tune header setup from before. Remember this is also with his ARH mid length headers as well which makes it even more impressive. Over 100RWHP and 50RWTQ. LFG
