People are starting to dial these things in since the ECU has been cracked. LMR already has the record for the fastest C7 running deep into the 7s. No doubt this thing will be in the 8s soon.

Left pretty soft, guess that's why it picked up damn near 30mph on the back half. Things are definitely getting interesting with these cars now.

Very nice.
What were the mods?

Badass.
On a side note: Maybe someone can shed some light on this. I remember reading an article about the LT5. It stated the engine uses the Z06 LT4 pistons and rods in the LT5. Can someone confirm or deny this? I’m curious if it’s factual or not.


Pick your poison.

Are there any factory blower demons going 150 mph?

This ZR1 will be a 150 car real soon it appears.

Shits crazy!

Not sure, but interesting they both are the 2 cars to have the largest factory blowers at 2.7L. The ZR1 with the 2650 Eaton TVS and the Demon/Redeye with the 2.7 IHI screw.
They’re about to have company with a 2650 TVS/DCT car soon....

From Ben at WeaponX

The ZR1 E99 ECM is new, which communicates with the new Fuel Pump Injector Control Module for the port injection, so differences in firmware will likely make a port injection retrofit package very difficult since the new ECM's firmware will likely not communicate easily with the previous Z06 E92 ECM.

The M7 and A8 transmissions are shared, but I'm sure the ZR1 will have the latest and greatest programming to not only account for the power, but also improved shifting.

The LT5 and LT4 use the same low side tank pumps so anyone wanting to run ethanol or big power will still need to address this.

The LT5 and LT4 use the same high pressure fuel pump and injectors.

The LT5 and LT4 use the same cylinder heads.

The LT5 and LT4 use the same pistons.

The LT5 has an AFM-less valley plate.

The LT5 has different crank and connecting rods, likely for the added power.

The LT5 has a different camshaft.

The ZR1's front wheels are .5" wider; however, only 5mm of that is to the outside, so I do think the car is slightly wider up front, but how much I am still unsure. I'm hoping for 1".

The ZR1 uses a triple heat exchanger system as well as shares the center heat exchanger with the Z06, but that PN changed for 2019 as well.

The ZR1 uses TWO heat exchanger pumps for the separate coolant brick loops like we do on our ATS V kits.

The ZR1 has a 95mm throttle body vs the Z06 87mm.

The ZR1 has a different pressure active exhaust; however, I'm not sure if this is accounted for in the bypass valves with the operation, or it's an entirely different exhaust.

Nice. RPM was having issues with the blower bypass valve which is essentially a huge TB. Apparently it was limiting power on the big end causing the lower trap speeds previously seen.

I saw a CTS V3 crack 1000rwhp on instagram with the LT5 blower swap so the potential is definitely there.

Are we ever going to get a mod list?
From their FB page: Late Model Racecraft

The modifications are limited to the following:
- GM Performance CAI
- American Racing Long Tube Headers
- Lower Overdrive Balancer Pulley
- Custom Camshaft
- Tune

This is still stock untouched blower, cylinder heads, fuel system, with no auxiliary fuel adders or methanol injection.

Nuts. That is only like $5k of mods.
