It has taken a while to bring everything together but today the rewards for all the hard work, the implementation of the design and seeing it work on the dyno was amazing! This is a completely stock longblock LT4 with the original Cam, Supercharger, and fuel system. what I have added is an e85 sensor, our custom plug wires, JLT Performance intake, Brisk RR14S plugs, Banks Power iDash, HP Tuners software, American Racing Headers 2" primary to 3" collectors with OEM NPP Muffler and thanks to Gabriel Griffin for supplying the ATI Balancer with the 9.20" lower pulley and ATI Balancer.

Another huge shoutout to Improved Racing for their CCR catch can and the patience with shipping parts back and forth so I could create a truly closed Catch Can system that is flawless!

Today this car made an easy 723rwhp & 808Lb/ft of torque on Shell 93oct pump gas with a measured 10% ethanol content. We made 4 back-to-back pulls without any cooling in between, pretty much keep ing the car running for nearly two hours on the Mustang Dyno. Our final "Track Safe" pull hit 788whp and 839Lb-Ft of torque... making this ZLE to soon be one of the fastest vehicles to hit Daytona, Sebring and other tracks!!

Check out the video and LMK if you want to unlock the true power of your ZLE without all the hype!

These dyno numbers are stupidly high for the mods listed, I would like to know the baseline stock numbers for reference because the math don't math here.

[SpeZ]

Very good results

[AZIROC]

Very cool. Im guessing ported blower? Any link to the LMK place?

Wait - is that Gabriel's car?
It has a lot more on it than what was listed.

I tend to agree. Look at my numbers and build to obtain similar results on a Mustang dyno.

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.

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.

Why is every dyno you post severely inflated? You went from 700 whp with only cooling upgrades, to 790 whp and a 7.5s 60-130 dragy. Nothing adds up, except your builds are always an anomaly with some super secret magic sauce. Or designing an exhaust with AWE that turned out to be another fabrication of the truth...

Thats where im alittle lost. 585 to 700 with a cai/tune and better cooling? Im guessing full E85 as well?

Absolutely unbelievably amazing results David. Congratulations!

In your original post #1, I can quote you as follows:

"Today this car made an easy 723rwhp & 808Lb/ft of torque on Shell 93oct pump gas with a measured 10% ethanol content. We made 4 back-to-back pulls without any cooling in between, pretty much keep ing the car running for nearly two hours on the Mustang Dyno. Our final "Track Safe" pull hit 788whp and 839Lb-Ft of torque... making this ZLE to soon be one of the fastest vehicles to hit Daytona, Sebring and other tracks!!"

I have to ask were the final results with an Ethanol mix of e20, e30 or even higher?
Because in your post you clearly state the original results where: "723rwhp & 808Lb/ft of torque on Shell 93oct pump gas with a measured 10% ethanol content"

But you never mention going to an ethanol mix for the final results in your original post or your follow up post this morning.

Or did you just conveniently forget to mention this?
Just curious since the numbers are so good>

[djctoto]

No need to answer my question about the Ethanol mix on the final pull and results because I just found your YouTube video on the same car and results and now know that the 788whp and 839Lb-Ft of torque... were achieved running E40.

With the addition of headers on my car I spoke with both Ted the owner at Jannetty Racing Enterprises in CT a shop very well know for their builds and tuning on LT4 Camaros and Covettes as well as the owner of the shop where I ultimately had the re-tune done on my car and both had expressed concerns about running an E30 mix.

Is running an E40 mix with a stock fueling system really safe?

Because I also distinctly remember you telling me when you tuned my car on E30 that you had run yours with the stock fueling system on E40 but this was on the "hairy edge"

Those dyno numbers are ridiculous and not accurate at all for the mods listed. Its literally impossible. That car would dyno 100WHP less on any other calibrated dyno.

These are legit WHP numbers for headers and intake on a ZL1 from a well proven shop. Quite a difference as you can see.

If you watch his video you'll see the final numbers were obtained running an E40 mix with a completely stock fueling system and it's still "track safe"

Must be the proprietary magic!

[QUOTE=Patriot Motorsports USA;11516221]We did not Baseline this car because like every other ZLE, they put down 585hp.

Funny for every dyno result every posted by Patriot Motorsports USA or in one of their videos there has never been a baseline dyno pull done first. I wonder why? It doesn't take that long to do and is the only way to get a meaningful before and after comparison for the tune.
And It certainly wouldn't hurt the car to do a single baseline pull.

I'm not an expert by any means but you would think that even without being tuned the amazing cooling modifications would allow the stock tune to function more effectively without the need for the heat related decreases in engine timing and the resulting loss of power that seem to make the difference.
