Last night Kevin from Performance Autosport in Richmond came down with their bone stock 2011 GT for us to do yet another before and after JLT CAI and tune test to confirm the past results we've seen.

We strapped it down and did 2 runs to make sure it was making good stock power and it was, 361 RWHP and 334 RWTQ. This is exactly what our Kona car did stock.

After a quick install and tune upload we made some more pulls. Run 3 was a blunder as it was made in 4th:nono: by mistake so run 5 was a pretty hot run with coolant temps above 200.
This resulted in a 384.92 RWHP and a 363 RWTQ for just shy of a 24 RWHP and 30 RWTQ gain.

To be far we let the car cool for 30 minutes and got coolant temps in the 175-180 range, more equal to the stock run and bam, 391.6 RWHP and 369.64 RWTQ for a grand total of 30 RWHP and 35 RWTQ gain from nothing more then a JLT CF CAI and JLT custom tune.:rockon:

The tune was not adjusted and is the same tune we have been running in our car minus our header adjustment for weeks now.

We also remove the skip shift in the tune as well.

I'm working on a video now and hope to have it up sometime today.

Big thanks to Mark and Kevin at Performance Autosport for the car and time.:beer:

Thanks
Jay

Why do we see so many of these cars stock dyno at 370-375 and then a few at 360-365?
Same goes for autos, 350-355 and then some 360-365.

A 10 RWHP swing between different cars and different dynos is nothing.
So far my grabber loaner, my Kona and this car all dynoed 358-361 stock on the same dyno.

I question cars that dyno 390+ stock :)

You have to love your honest and straightforward testing and hp/tq gains and no smoke and mirrors. Great work. Have you guys tested any auto's? How are your tunes for the auto?

Had an Auto run 10.98 with a 125 shot 4-5 weeks ago and 12.2 with just our tune, headers and bigggs/littles :)

More auto testing coming up

Yes, I agree on that autos. More focus on these would be greatly appreciated as I'm really digging the carbon fiber intake.

Why does my M6 with 3.73's put down 386 bone stock?

That's just what your dyno happened to say. Not that it's right or wrong, just too many variables to compare numbers from different dynos. The only valid comparison that you can really make is comparing before and after numbers from the same dyno when modding.

Run an engine dyno test on any randomly selected engines straight from Fords production line and I'd bet they are all within 2-3% of each other. If some engines were truly 30hp or more different, Ford would have the worst quality control in the business. Things like that just don't happen these days. The level of QC rigor used today by the OEM's (6 sigma, ASTM, SAE, ISO, etc) is ridiculously stringent.
