Herold motorsports build

2018 hyper blue metallic ZLE
Started off with first round of mods about a year ago.
Installed myself at the house.
CSP 2" headers
Rotofab big gulp
NW 103mm tb
MAD ported supercharger w/ stock size griptech pulley
DSX flex fuel sensor
Katech 174* thermostat
Firecore wires with pro mod boots
NGK plugs
MM mild catch can with road course top
ADM v2 supercharger coolant reservoir
JMS voltage boost
AEM wideband
Aeroforce interceptor gauge
ZZP A pillar dual gauge pod
ATI balancer with DSX 8.6 lower pulley
All SPL suspensions parts front and rear except rear knuckle heim upgrade
Herold Motorsports custom engine tune

No baseline numbers but hit 577 whp 610 wtq on a Dynomite Dynomometer. All street tuning. According to the shop, typical dyno numbers are 15-18% lower than dynojet. Dynoed on e27 and highside was at the edge with .80 lambda.

Round 2
2/19/22,
Parts had already been ordered and took the car out for one last romp. Oil pump failed at 15k miles on the way back into town after 2 hours of driving. Towed home, then ordered transport. Car was picked up yesterday, Houston bound. Sent to Spencer at Herold motorsports.
Mods,
Katech oil pump
MAD ported heads with ferrea super alloy exhaust valves and port matched w/ the supercharger
CHE trunnion upgrade and bronze valve guides
Johnson short travel slow leak down lifters
DOD delete kit with custom valley cover
PAC .660 lift dual valve springs
Manton pushrods
C7.R timing chain
Herold Motorsports custom ground LT4.R camshaft with 38% fuel lobe
ARP hardware
PLM standard size heat exchanger
Pierburg CWA 100-3 intercooler pump
Magnaflow xpipe muffler w/ 3" inlets and outlets
Herold motorsports dyno and street tuning (MAF and VVE)

Car should get there tomorrow and once parts are received install will begin. Pretty excited at this point and can't wait to see the results. Our wedding is at the end of March and hoping It'll be back in my possession by then. Worked with Spencer since day 1 on mods and goals. Great guy and always answers any questions and quick with advice, especially when I was installing first round of mods.

Question now is do I fly there and drive it back 1500 miles, or have the guy who drove it out there bring it back. Will get that figured out in the next couple weeks, time to make some more POWER
