My Shelby's Built Engine Is Tuned At Last

I had some kind of weird falling out with my tuner and was looking around for someone to finally get my built motor tuned. Someone I trust called me, made a recommendation and set me up. The only down side was it was 6 hours away, but what the heck, I needed tuning bad.

Drove down this past Friday to Boynton Beach FL and spent the night. Drove over to the speed shop Saturday morning and met up with the owner. The tuner showed up on his Yamaha sport bike. Anyway, I told the tuner I didn't want to drive 6 hours from home only to have my car blow up on the dyno so he tuned for safe power.

Tuned first for 93 octane - (R+M)/2. Results - 650 rear wheel hp and 648 rear wheel torque. Then they drained the remaining two gallons of 93 octane from the gas tank and poured in some C16 (117 Octane). Results - 690 hp and 669 torque.

Put the two gallons back in that we drained, loaded the 93 octane tune, hand shakes all around and I was gone. Opened it up on the turnpike through the first two gears (Florida Highway Patrol was everywhere) and, whoa - I've felt power before, but the only way I know to describe the difference is that I've never felt the power come on as smooth. When I got home I took my wife for a spin and opened it up through a couple of gears. She commented on how smooth the car was. Damn, even my wife noticed.

Can't wait to take her to the track. I'll definitely run the race gas tune. :)

Hello Lawman I had a Mustang GT 2006 in 2010 was pretty cool, now I have a camaro SS 2010 and I can only say its a big difference in quality compared to the Mustang, im not sure I will ever buy a mustang again, BUT now they come with the shelby 2013 with 650hp, that is sure interesting, but they still have this stiff rear axel, thats just not up to date.

Thats getting close to the power output of an F1 car! I think the most power I have ever handled was close to 500 bhp (at crank) I guess you have after market traction control?

zeus I hear what you say about the rear axle. I read (cant remember where) that a company where selling a kit to make the rear suspension fully independent on the Mustang. But even with a fixed axle, it should be up to the task if the ride is nice and firm.

I would love to be able to own somethign with real horsepower over here, but having just spent 105 to fill up the Audi I think it would send me bankrupt lol

Mack.

>>I guess you have after market traction control?

Rudimentary traction control from the factory. I turn it off at the drag strip as it just seems to get in the way. Now a gosh-awful-for-real traction control I could live with.

>>but they still have this stiff rear axel

Works great for the type of racing I do. Besides, I've replaced the upper and lower control arms with after-market items. I'm thinking of replacing the panhard bar with a watts link.

>>the most power I have ever handled was close to 500 bhp (at crank)

With the race gas tune, hp at the flywheel should be somewhere in the neighborhood of 810.
