My Stock Dyno Numbers

[TonyJ5150]

Ended up with 415 tq and 499hp...First stock pulls were 380tq and 459hp. So a gain of about 35 tq and 40Hp.
It is definitely louder. It has a commanding bark when you give it a quick rev...turns heads for sure. Performance wise, its feels quicker, especially above 4k. Driving in the quiet mode, its not much louder than stock, but when that valve opens, its a huge difference.
Ill try to post some audio, but need to find someone to hold the mic while I drive off...

looks like the stock runs were ran with enough oil temp for full rpm and the others were not.

Nice numbers. So:

459.16 - Stock
483.37 - Stock Tune, JLT Intake, Kooks Headers, Kooks X-pipe, Stock Muffler?
498.84 - Tune with the above?

Who did the tuning?

Corbin Johnson I believe. I spoke with him this evening.

Corbin of Johnson Tuning did the tune, we did the install. Corbin is our in house tuner.

Pleasure working with you Tony, beautiful car!

Correct

You ran the JLT with stock tune?

 

[TonyJ5150]

Looks like for that dyno pull it was not tuned yet, but had the intake and exhaust work complete..so yes.

Late to the thread, but my C6Z with Halltech CAI and tune put down 483. So, for this 315 cid fpc to put down these numbers is truly amazing.

My dyno run. Car is bone stock. They did an open house at the shop, so I don't think the dyno was perfectly set for each car. Temp was 93 degrees and 86% humidity.

434 hp / 335 tq

Mustang dynos read lower than Dynojet.

Also OP: didn't you do 463whp stock? So the real gain was 36whp.

 

[ben@fatfab]

Stuntman that would be my fault. When I sent Tony the stock dyno run I had the smoothing turned down which will show a few more HP then when you put the smoothing up as it was in the last runs posted.

His overall gain was right at 40hp.

Also Mustang dyno's are typically known for reading low, yes, if setup right. However they can be easily manipulated so you cant always assume its reading low.

Pretty good numbers for a stocker indeed. Tune + LTH results are about right.

 

[Stuntman]

That doesn't make sense. You made 463.26 on smoothing 5 (the most smoothing) in your OP. I can't tell what smoothing you used in the comparison but it still would appear the gain is 36whp.
