Road race ZR1 getting some upgrades with @peitzperformance and some calibration using @hptuners #repost @peitzperformance ・・・ Okay folks, heres the latest from our Charlie Package R&D on the @thesheelycollection 2019 ZR1! She ended up gaining 120 RWHP, up from 580 stock to 702 SAE on our Mustang dyno. Current Mods include an Innovators West 9% larger lower balancer, long tube headers, thermostat and tune! It is on full E85 but we left timing conservative because this is a road race car and load and temperature are two big factors for the customer. We couldn't be happier with the results! Were off to LS Fest next weekend! This car also features @ult_performance JRI shocks with custom valving and coil springs, @_lgmotorsports sway bars, drop spindles, and spherical bearings! Not to mention a beautiful set of @forgeline GS1R wheels wrapped in @bfgoodrichtires! Of course, tuned with none other than @hptuners! Special thanks to Dave Steck of @dsx.tuning for supplying a spectacular auxiliary fuel pump system and some greatly appreciated support! #innovatorswest #corvettes #ppttuned #pptbuilt #hptuners #driveoptima #driveusca #godriveit #roadracing #c7zr1 #autocross #kooksheaders #thesheelycollection #dependable #lsfestwest2019 #lsfest #ultimateperformance #dsxtuning https://www.instagram.com/p/Bw4wjhOF3iL/?utm_source=ig_tumblr_share&igshid=1k1kbmafuk77o
