Calvert Racing Suspension goes 8's in a S550

[jkstang78]

The story behind this car is that it might be a test car for a 2016 Cobra Jet. I'm not entirely sure what the full setup is on this car. Trying to find more facts out. I do know they built a solid rear axel for this car. (There was a photo of it but has since been taken down) It does have a Supercharged V8 in it. Also don't know what transmission they went with. This is a full race car.

From their facebook page.
8.97 @ 151mph, We built this car during the past 5 months at our facility and couldn't be happier with the results inside and out! Thanks to all our supporters who helped us accomplish this! Might possibly be the first S550 Mustang in the 8s!

From someone posting online in a thread.
"If is a CJ for all intents and purposes. There were only two CJs built this year. Ford came to John to enhance/ integrate a solid axle into what was an independent rear suspension. This car was built, disassembled and rebuilt several times to optimize the suspension. The 2016 CJ buyers can rest assured that thanks to John Calvert they are getting a race car that can hook in a car wash!!!"

Congratulations. Very cool. Interesting that one uses the rear entry Whipple. I know from Watson that they were instructed by Ford to use the IRS on their Cobra Jet development car. I have no clue what Culverts connection to Ford might be if there is any at all. But my guess is Ford must have at least predicted that someone would do a solid axle car and that is why they insisted that Watson do an IRS car. Watson has been the outside contractor for the Cobra Jet production for Ford so it remains to be seen what the final CJ designation will be.

Maybe they wanted to see what someone can do with a SRA. I know they have raced a few Cobra jets over the years.

I also found the picture of the S.R.A.

Damn, my photo above of the rear suspension got around quick. lol

Congrats to the Calvert Team! Those guys do good stuff, that is for sure!

I wonder if the straight axle will ever see production? I was told no one would do it. Glad to see it done.

I wonder what modification is required to make it work. I doubt it's a direct bolt on.

Only a matter of time......

good work!

 

[BMR Tech]

Of course people would do it.

"drivers" wont do it....because it's silly to chop the entire rear of the car up.

It may see production. But it's going to take a ton of time, money and effort to make it work.

Love this car, there willbe a ton of people buying SRA conversions. Mustangs are the most popular car to use in drag racing. It may take a few years, but people will be ripping the IRS out and installing SRA by the bunches.

I want to correct my post above I misunderstood what I was told a while ago. The Cobra Jet cars will have a solid rear axle. Ford asked Watson to build their car with a IRS to see how it would stack up. A number of bare bodies were given to a few teams one was Calvert they choose to build their own design solid axle set up instead of using one with the parts Ford gave them so this is different than the Cobra Jet cars.

Now what can be observed from the pictures that car has had extensive surgery and with a lot of additional tubes welded into the chassis and what appears to be a 7.5 second cage so maybe their goals are a lot higher than the impressive 8 second run.

subbed. cant wait to see what this leads to.

 

[Poppacapp]

Meh.. No reason to put a SRA in the car due to the OEM IRS looks like it will be good for 8's. Waste of money on a SRA.

I actually saw these pictures on facebook page. So yes the pictures got around quick. If i was ever to sell my 91 race car and turn the 15 into a race car. I would go SRA for the strength. Otherwise as a street car the IRS is fine.
