We did not Baseline this car because like every other ZLE, they put down 585hp.

No, this was a stock blower with the noise abatement plate removed.

It has a lot more on it than what was listed.

No, I bought several parts from GMS as Gabe has great pricing and fast delivery.
This is a car that I started down a path a few months ago of removing all the things I feel hold back the LT4 from performing at it's best. I removed the OEM Catch Can system and designed a better one, keeping the auto drain function so it can remain a closed system and be legal to Track at any Road Course in America.
I removed the OEM thermostat housing which is known to break if the belt fails, and used the
DMS Billet thermostat housing which uses the proven LS3 style 174º thermostat.
The entire supercharger cooling system was upgraded but keeping the stock pump. ALL the hoses with the exception of the one between the SCHX and AuxSCHX were sized at 19mm to increase flow, but also to slow the flow down. As each pull was made, the MAT temps would DROP as the engine would accelerate in 7th gear (1:1) to the limit. We use 7th because I WANT the long pull to show any abnormalities as this is where this car lives on the Road Course under full load. My customer asked while watching the pulls, "is running this hard on the dyno hurting the car...?" With a laugh I responded, "what do you think it does in every other gear...? And this is how I drive for 20-30 minutes a session non-stop."
After two hours on the dyno, making changes to a tune we began developing over a year ago with my car... this car has exceeded what mine currently makes and a lot of that has to do with how well the JLT intake flows. The MAF data was beautifully smooth, as was our spark table & timing. Our new plug wires never missed a beat and with all the abuse and this result will soon be duplicated by another we are working on this week.
I've shared the components and parts it takes as well as many configurations on how to make the LT4 ZL1s run reliably on the track. I have spent years developing what we have proven to work without any failures when it matters the most. If you've spoken with me on the phone or at the track, you know I'll give you the parts off my car so you can finish your race... and I am certain everyone wants to see logs but I am simply not going to share all of our info on how the sausage there is made. There are a handful of extremely well appointed Tuners in the USA and around the World, the majority of which are 100% focused upon Drag Racing which honestly is a completely different mindset than Road Racing applications. My Brother has been tuning Road Racing cars since the early 1990s and the way the power is used, applied or created is our proprietary right for our customers.
Thanks to everyone who made this build possible... there are more to come, each with possibly a new innovation I will share. I look forward to an amazing 2026 and hope if I may, help you with your goals to have a reliable track car.
