Pushing the 7.3L Godzilla to the LIMIT! Over 1000TQ!?!

We've been extremely busy at the shop knocking out project after project but in this video we give you a look at a few of our client's cars along with some more 7.3L Godzilla content. To kick things off we take a look at a C7 Z06 that we just wrapped up a stage two performance package on, a Mercedes AMG GTR that we installed a Forced Induction Interchiller system on, and of course some coverage of our Godzilla powered S197 Mustang.
We would like to thank Ole and Johan from OBR Control Systems for being generous enough to come down to our facility and work with us to test out their Godzilla control pack. In the very near future, you will be able to purchase a complete 7.3l Godzilla engine package from us that will feature their complete OBR Control Pack for your swapped hot rod or project.
Our entire industry is facing an extremely troubling and uncertain future as the EPA has changed their interpretation of the Clean Air Act - putting every manufacturer, installer, and user of performance automotive components at risk of not being able to continue to do what they love. Please take just a few seconds out of your day to follow the link below and let your elected officials know that you expect them to fight for the RPM Act, and save our racecars.

That deserves a like just for blowing up a new motor. Love it, this is how we all learn.

[@FiveBarMotorsports]

Thank you for your support Mark!

[@adamdodsy84]

Still more left in it with a good cam to move that TQ peak. If it's anything like the LS it will handle more TQ at a higher RPM before it goes boom.

[@CordellCars]

I'm really interested what these motors can do with a strong camshaft and maybeee some mild head work on 93 pump gas, then a smaller amount of boost like 7-10 lbs. I think that limitation is just as important to the average end user of this motor than the guys going for 1000hp+ and 8s in the 1/4. The coyote is so bottlenecked by fuel if you live in an area without E85 like myself. I'm making like 680hp/570tq on 10lbs (paxton) 93 pump. If a godzilla can make say 800hp/800tq on a cam + low boost setup on 93 pump. I would buy that over a built 5.0 simply because the fuel availability would still limit the built coyote's power whereas the Godzilla's ceiling would be a bit higher even stock bottom end. thoughts?

[@FiveBarMotorsports]

Once we have the methanol engine in the S197 we plan on doing some more practical testing with the engine in another chassis. Brian Wolfe over at Willis Performance Enterprises has a lot of great content on some NA applications on the engine dyno.

[@PaulSter]

Yep, that's where I landed with my 550. No E-85 anywhere near me, so 93 octane was it. Heck, I was glad to even have one station near me with it, but just one.

[@kskip4242]

E85 is needed on this Godzilla

[@Joebauers2505]

you have the same issue no matter what engine base you use, higher horsepower/torque requires better fuel simple as that.

[@70_Torino_Guy]

OUCH! At least we know a bit more what this block can handle.

[@PaulSter]

I know we're 10 mos past, but bravo to you guys for taking one for the team on the Godzilla. Lot of good data for y'all I'm sure. Of course, now I'm gonna see where you've gone with it!

[@Edward135i]

As soon as I saw those cooling channels that ford cut between the cylinders I knew that would be the weak point for this motor, sucks that they come like that.

[@mikelliteras397]

It is a weak point but that’s all relative. Being 7.3l it doesn’t need a lot of boost before it’s undriveable on the street and as soon as it gets out more and gets on the track more, someone will build a beefier block. It should still take a ton of power before it breaks.

[@giantpune]

Thumps up for blowing up a brand new motor! Everybody goes to the hockey games to see a fight. We go to the oval track races to see some wrecks. And we come to the youtube dyno videos to see some people blow some stuff up. You guys did not disappoint. And now the armchair warriors of the internet will have a video to link back to while getting into arguments with strangers. Stock godzirra motor is only good for 850HP. Any more than that and the block parts like the red sea. :P

[@FiveBarMotorsports]

After going back through the logs with Johan from OBR, this engine made the power that it did on seven cylinders. The original OBR Control System did not like the 16 volt system we are running the car on and fried an ignition coil driver. We're fairly certain that this contributed to the engine failure we had. People can talk all they want. This platform is only getting more and more popular as the days go by, and we're more than okay with being the folks that are completely transparent about what works and what doesn't work. :shrug:

[@giantpune]

@@FiveBarMotorsports That reminds me of a 1972 comet I had in my younger days with the inline 6 250CID. I drove it around on 5 cylinders for quite a while. It had a nice loppy idle to it.

[@allaboutpcpairguns7069]

It was a beast for stock

[@TBirdKris]

When I saw the cracked cylinder my first reaction was to think it had a weak(ish) block. But then I saw the other bank had a missing rod/piston. I believe the cylinder wall broke due to hydro-locking as I've seen this happen before when a motor took in water. My question is where did the coolant/oil come from? Blown head gasket or did it come from the dead hole in other bank? What caused the piston and/or rod failure? Power? Detonation/knock? Possible hydro-lock from a head gasket failure? Have you guys figured it out?

[@FiveBarMotorsports]

We're going to be releasing a video very soon explaining exactly what transpired. Interesting stuff.

[@kskip4242]

Cheap 93 gas is what happened. With e85 this would not of occured.

[@danielbargas3377]

Wow I was Genuinely surprised by the block failure, I wonder if the saw cut is a weak link and can be filled with something like mini block Guards between the cylinders.

[@FiveBarMotorsports]

We are still going through to determine what went wrong first but it is our belief that the cracked cylinder wall is something that was a biproduct of piston/rod failure and that debris circulating inside of the engine.

[@danielbargas3377]

@@FiveBarMotorsports was that the same cylinder the piston failed on? I’d think the factory iron block would be good for more than 1000, the torque was huge across the board though. How much total timing do you have on what fuel? Just curious

[@billb410]

@@danielbargas3377 Yup a compacted graphite block of this caliber should be good for way more. My guess the block failure was caused by piston/rod failure or trying to compress water from a head gasket failure.

Why are the Australians , putting down quad digits at the crank with less boost on positive superchargers over there 🤔

[@FiveBarMotorsports]

If you account the 18-25 percent drivetrain loss (depends who you ask) the power we are putting down is in line with folks who are testing on engine dynos. Thanks for the comment.

[@brandonknight7240]

How am i supposed to get thrilled about a big V8 making 1000 hp or torque when 4 cylinders half the size regularly make 1800 hp or torque on the same dyno machine? So why cant people find 2500 or 3000 hp with the coyote or the "godzilla 7.3"?

[@riogrande163]

1800 *torque* with a 4 cylinder? maybe at 10,000 rpm or 100 lbs of boost maybe....

1000 tq 800 hp is the stock limit it knocked right before you got on it I think it was the RODS Time to go to a 100 turbo instead of the 88 with those torque numbers or giant cam to lose some torque and make more hp

We have not seen many folks putting down quad digit torque numbers with these to the tire. This is an MD1100 chassis dyno and we think it made some pretty impressive power before it let go.

@@FiveBarMotorsports I'm not saying this pull was unimpressive, it is very impressive. However I'm just curious to how these engines respond to different types of forced induction.
