2013/2014 Shelby GT500 Dyno Results

You're right, it's imperative that you get cool-down between runs. On a dyno you'd need 20-30 minutes between pulls. How much cool-down before the first run?

Before the first run it was about an hour.

Run 1: Mods: 3.73 gears, rest of car stock
601.3rwhp, 608.3ft/lbs on 14.3lbs of boost.


Run 2: 3.73 gears, Replaced factory filter and resonator with blue Airaid and FRPP resonator delete:
597.6hp, 618ft/lbs on 14.6lbs of boost. Dyno operator mentioned he believes the car made slightly less due to the motor being hot. Only waited 4-5 minutes between pull #1 and pull #2.
-4hp, +10ft/lbs

Run 3: same as run #2 but was done immediately after with no cool down.
594.8hp, 609.8ft/lbs
-7hp, +1tq

Run 4, 3.73 gears, Replaced FRPP resonator delete with JLT resonator delete. Car was allowed to cool down for 5 minutes during the resonator delete swap out.
593.8hp, 612.6ft/lbs
-8hp, +4ft/lbs

Overall was happy with the results, but wish I would have given the car more time to cool down between runs as hp kept falling off the table.

Modifications are in my signature. I was hoping for 700RWHP and the tuner stated he could get me there with a little more "aggressive" tuning but I declined! He also told me the ECU was pulling timing due to some pinging being detected. I have since switched to a tier 1 gas station. Next step a set of Longitubes and maybe a switch to a single blade throttle body.

2013 GT500 bone stock 574/539. Only ran it up to 6750 so it seems a little lower than most, but definitely not bad.

What kind of dyno is that?

Don't know much about dynos but they said its a dynocom 1800x

Looks like that may be a bit of a little older dyno model, regardless it will probably read lower than a typical inertia only dyno, as the dynocom uses eddy brakes (eddy current) to introduce more real world conditions. Only question I have is why your torque would be so much lower than your hp?

It may have just been the way the dyno was calibrated. I just picked up my car 2 weeks ago and was curious about the numbers and this shop offered to dyno my car for free. My first pull showed somewhere around 530whp which I though was way off. He put a fan on it for about 15 minutes and ran it again and it pulled the 574. I feel like it's pretty inaccurate if it gained 40+ whp from a fan because the fan wasn't even on it during either pull, just in between. Also, I doubt the car was heat soaked for the first pull because I only drove it for a total of 10 minutes that day and it was on the way to the shop and it sat for a good 25-30 minutes before the first run.

Lots of great numbers! Thanks to all for posting!

Kinda late, seeing as this was done back in March. But I figured why not throw it up. I get the feeling that the power is a tad low. But I was quite happy with the results nonetheless.

13-6 with 10%OD, LTs, O/H H-Pipe and stock catback.

I just ordered the exact mods you have from Van. Hoping for similar numbers.....

 

[hostile500]

VMP 67mm TB
JLT carbon 127mm CAI
2.4" upper pulley
90mm idler pulley
4:10 gears
borla atax mufflers

Before the TB it was a satan car 666whp with 666 TQ

Hi All. Long time lurker here. Made two runs on dyno between the thunderstorms and the best numbers were 568.53. Mods are not much:

Res delete
Blue Airade filter

Full tank of 93 with a bottle of BG booster thrown in for good measure. I have the graph but don't know how to post it. A little help would be much appreciated.

Thanks for sharing your results, Bill. Information about how to post pics is located in this thread. FWIW, I post mine from PhotoBucket.

Thanks for sharing. Those are BIG numbers! Any internal mods?

 

[NJredfire03]

Hey just saw this Sticky post. Here's my graph and numbers. The car was absolutely stock when dyno'd. Since I've only added a res delete and a KN. Best numbers were 575/602. Thrilled with the power this car puts down from the factory. Sorry, got some water on the paper. Also, first run, car wasn't fully warmed up.
