Lots of great projects in the back shop are keeping us pretty busy.

And.. getting ready to travel back East to Boston in a couple of weeks to work on 4 Superformance MKIII's. Two Superformance MKIII's are Gear 6 buildouts ready for typical maintenance & oil change. Two other Superformance MKIII's (not ours) are in need of tune ups and/or repairs?

Owners are splitting expenses to fly Wayne out to work on their Superformance MKIII's in person. Superformance technician for hire.. updates & pics to follow.

We'll be closed the week of Friday, Aug 23rd, thru Monday, Aug 26th.

This Superformance MKIII SPO 2910 in for some upgrades and tuning. This particular Superformance MKIII served as the show car for Superformance and Roush for 2 years.


An Updated SPF MKIII SPO 3068

SPF MKIII SPO 3068 / Indigo Blue/Silver Stripes 

When too much isn’t enough, you add more!!

This beauty was a beast before, but now it's evil wicked mean and nasty, and yet surprisingly easy to drive when you’re just cruising around. Step on the gas now and 637 horsepower gets your attention real fast.
This Superformance MKIII SPO 3068 came in for a lot more upgrades and some changes. Every major component of the car was reworked with the exception of the brakes and clutch.

We reworked the engine changing the camshaft, intake manifold, carburetor, valve covers, and air cleaner which resulted in 637.4 horsepower at 6,600 RPM and 588.1 Ft. Pounds of Torque at 5,100 RPM (see dyno sheet .pdf here) Engine work by Mikes Racing of Boise, ID. The transmission was blueprinted, carbon lined syncro’s were added and the 2nd to 3rd gear shift rails were modified. The rear end was changed from a 3.27 to a 3.45, Olthoff Racing suspension replaced the stock setup, polyurethane sway bar bushings were added, and Fire Fly polished Stainless Steel Side Pipes were installed.

Overall the car runs better, drives better, rides better, corners better, and just screams authority while setting at a stop light. And.. it's a show quality piece. I guess this is a good example of too much is just right. Safe driving & enjoy the ride Dewayne!!


Delivered MKIII SPO 3068..

Summer has come and gone.. we've been busy and barely noticed its the Holiday season already, wow how time flies..

Well this Superformance MKIII SPO 3068 project was a life long dream come true for our new customer in Tennessee. What a fun project it turned out to be.. a surprise gift for new owner Dewayne, from his wife and son-in-law. He had always dreamed of a Cobra but was always too busy taking care of everything and everyone else to do it for himself.

Superformance MKIII SPO 3068 - Indigo Blue w/ Silver Stripes






Delivered to him in late August 2012, at his shop, and just after hurricane Isaac came through with severe storms still swirling around, Dewayne had no idea what was in the trailer when I backed up to his freight doors. And the look on his face when the rear trailer door was opened was priceless. Little did he know the Superformance MKIII had his Keith Craft FE installed in the car, something his family had secretly arranged to get to us at our shop in Boise. Congratulations to Dewayne and family. Enjoy the ride!
