We took our project X47R powered fiesta st to the track on Saturday for a roll racing event we waited for that was cancelled 3 months in a row due to bad weather.

This was actually our second run, the C7 owner agreed to a rematch after the fiesta won the first one. 2nd run the fiesta had about 2 car lengths on the c7 as well.

The car makes 325whp SAE and has a flat tq curve from 3,000+ in 4th gear.

That's awesome Tim thanks for sharing.

I saw another video recently with a similar showdown...

But seriously that's great. Always neat to hear what these Puma products can do. Daniel's G25-550 pulled about 10 car lengths on a 2018 Vette a few weeks ago, it still had the dealer tag on the back....

I own a 2008 vette, no power mods. I took it out and ran a couple 12.6 1/4s a few years ago. As much as I’m excited about modding my new ST. My vette is a cam away from destroying any fiesta if needed. Different tools for different purposes is my take. I love throwing a lightweight car into an exit ramp hard.

I am SURE that our cars can be modded to be VERY impressive!

But my brother's '06 C6, (LS2) with just a F.A.S.T. intake manifold, Vararam Intake, OBX headers, mild stall converter, and drag radials went 10.78 @ 127.30 on a great DA air, mid November night at Atco. ;)

Your 325 whp sae using spray on x47R or just x47R by itself?
If sprayed how much of a shot?

No way, there is a cam on that car for sure.
Nope, no cam, no aftermarket/ported/polished heads, but it did have a Cartek tune by Julio, he pulled every little bit of factory weight he could out of it (including the passenger seat) without adding in costly lighter parts, and no front sway bar as well.

Did I mention perfect 'air', and a recently prepped launch pad?

no spray the bottle is out of the car since the clutch didn't like it. All runs have been x47r only.

that's impressive. I honestly don't trust everything on that corvette forums thing. Usually factory freak cars aren't 2 second fast in the 1/4 then most other people.

For the sake of this thread, bottom line is a stock automatic LS2 vette should be low 13s, high 12s.

OK, but I went 12.67 @ 112.60 in a MANUAL 4th gen, LS1 Z28, in near 'perfect air' at Atco with just an air box lid, Eaton Posi diff, Pro 5.0 short shifter, Nitto drag radials (but still full size, 275/40-17 sticky fronts), and a larger aftermarket front sway bar, and also an otherwise full road race type suspension to abjectly HURT my launch/60 foot (and I am not all that great of a quarter mile 'driver' [wink]).

Believe it or not.

I don't drag race much anymore, but an LS1 with bolt ons trapping 112 on a good weather day is more realistic than an LS2 at 127. 127 traps is like 500 whp in most cases, right? I'd be curious to see dyno slips to compare on cars like these.

I got curious about the C6 Z06 list, guys with light mods are getting low 120 traps
