Help out a new guy?

Hey guys I need some help.
My car is a 2012 Gt500 with a few bolt on mods-

Headers and H-pipe
JLT Performance Cold Air Intake
Ford racing 65MM Throttle body
Metco Motorsports 2.6 inch Pulley/Auxiliary Idler Pulley Kit

I just had it dynoed for the first time
it was 529hp/465tq
does that sound about right?
If so what should I look at next for a little more power?
any help is appreciated thx!

Sounds a little low for those mods. If you have stock injectors that would be a step along with a smaller pulley.

I thought it sounded low also but the ppl that ran the dyno say its spot on?
I will look into injectors thx!

It's difficult to get the stock supercharger (Eaton M122) above 550 rwhp without porting and other costly mods. Most of the dyno results are in the 525-550 range for your mods so I think you're in the ballpark on horsepower, torque looks a bit low though.

That torque curve on your dyno doesn't look right at all. It should be peaking at ~4,000 rpm, which tells me you're not making the power you should be in the midrange. It could be heat soak, but it could be a tune that's not quite right. While not a cheap upgrade, slapping a TVS on top would be the biggest bang for the buck.

I forgot to mention I have also upgraded my heat exchanger to help with heat issues. do you think even with that done I could be having heat soak issues?
the tune is from Lund not sure if I should try and have an in house tune done?
thx everyone!

Has Lund seen the dyno? If not, send it to him and see what they think. Heat sink can still happen, especially on a dyno where air movement is minimal. If the dyno facility used fans in the engine bay and on the front of the car, maybe not. Doing a dyno without doing a data log makes it hard to do anything but guess.

ok i sent Lund the Dyno and will see what they say! thanks again!
whats the difference between say a whipple SC vs VMP tvs?

good read thx!

We tend to stick with the Whipple blowers on all of our GT500 builds and have great results. Very reliable superchargers and run lower temps. Any questions feel free to reach out to us or check out our blog, we do a lot of in house GT500's!

Yah that torque curve doesn't look right and it looks low... I attached mine just to show you. There are 2 curves... The low numbers are with Lund Racing and 3 sets of data logging. The high numbers are the dyno tune I got wiht PSI Motorsports here in Houston. The low number should be similar to what you should be seeing.

I would definetly get it looked at by Lund or if there is a good Shelby tuner around, get a dyno tune.

Thanks for all the info guys! Im in contact with Lund they want me to do some data logging and get back to them.
