This GT350 is back on the road again with a fully built powertrain and our 1000R twin turbo package 👀💪

When the owner learned that his stock GT350 engine was hurt he decided to send the car to us for a complete overhaul

We sent the hurt engine to our partners at Fast Forward Race Engines where they upgraded it to our 1200R spec

While everything was apart the owner decided now was the time to build the transmission so we sent the stock TR-3160 to Calimers Transmissions for their stage 3 build

We also added a few custom touches to set the car off appearance wise including OEM GT500 valve covers and a custom set of BC Forged wheels 👌

All said and done this GT350 has been given a fresh start with a built powertrain and some extra horsepower 💪

KING OF THE ROAD 👑🐍

This 2021 Race Red Shelby GT500KR Wide Body came in for our 1000R upgrade package 👀

Shelby American produced just 180 total GT500KR's from 2020-2022. Equipped with a Whipple 3.8L supercharger system, the GT500KR is rated at 900+ crank horsepower which translates to just over 800 rear wheel horsepower on our DynoJet chassis dyno.

With our 1000R upgrade package this particular GT500KR is now making over 1000 rear wheel horsepower 💪

This is hands down one of the nicest GT500's we have had the pleasure of building 😍

This 2021 GT500 came to us straight from Shelby American after it was outfitted with their Signature Edition Package with the optional Wide Body upgrade

After a conversation about the goals and expectations for this car, the owner opted for our highest horsepower offering which is the 1400R twin turbo package. We also carefully spec'd out tasteful custom touches throughout to make this build something special including: color matched roll bar, color matched brake calipers, titanium upper intercooler piping, custom spec BC Forged wheels with color matched beadlock ring and a custom carbon fiber steering wheel from Ukie Carbon.

The finished product is a GT500 worthy of winning best in show at the car show AND runs 8's in the 1/4 mile

Dyno results:
1426 whp 1013 ft lbs on E85
900+ whp on 93 octane

This 2025 Shelby GT350 is heading home this week to the lucky owner! 😎

The 2025+ Shelby GT350 comes from Shelby powered by a Gen IV Coyote equipped with a Whipple Superchargers Gen VI 3.0L supercharger system rated at 810 crank horsepower

When the car arrived at our facility we performed a baseline dyno test which resulted in 680 whp and 581 ft lbs on 93 octane

We then upgraded the existing 3.0L supercharged powertrain to our 800R package spec resulting in a dyno proven increase of 150+ horsepower 😈

Baseline: 680 whp 581 ft lbs on 93 octane
800R Upgrade: 831 whp 616 ft lbs on E85 💪 (800 whp on 93 oct)

Along with our standard 800R performance upgrades, we outfitted this GT350 with a custom set of BC Forged wheels wrapped in Toyo R888R tires and a host of Anderson Composites carbon fiber exterior components giving this car an entirely new look 👌
