New RCF HP record??

New RCF HP record?? video added 9-10-16
So i visited my Local performance shop http://weaponxmotorsports.myshopify.com/ in town that had a Mustang dyno, just to check my AFR while under the nitrous hit.My First pull NOT ON THE SPRAY shocked me completely i expected to have around 420 to 430whp. But what I put down was 468whp and 380wtrq. The temp was mild 75 degrees. They got tach signal from my Coil pack one. The number has been SAE corrected I will try to visit another dyno possibly a dynojet when i have time so i can confirm the number.

I think i am at the limit for the stock fuel system and the transmission capabilities. Nitrous being safe is only as safe as you make it. I have followed the footsteps of the ISF boys and have talked to 2 other RCF nitrous owners. They were using 200 shots. like i said i think the car's ability on stock fuel is 600 whp

just a different perspective since Ive asked a few folks.....
" Mustang Dyno, the results can be all over the place. Also the curve seems to be off, as RCF’s do not hit peak power at 7200. They actually peak around 6300 and stay flat (due to the cams).
So…. If his is peaking at say 7000… and since the Mustang relies on calibration of wheel speed and RPM (user input)
So… if 7000 is really something lower, like say 6500, and since HP=(RPM*Torque)/5252… that would account for a reading that is 10% too high. If the RPM-to-wheel speed error is just 300rpm, then the error would be 6%... and 6%*430hp=about 25hp."
Not my words yet just another scientific view of how the numbers can lie on a dyno. This car defies all logic against many on the forums. Yet per the above, it lies directly in line with many's dyno graphs. Being a spectator, Im inclined to agree with the stated hypothesis

This is why I'm not overly fond of dynographs. It's also why I establish good stock baseline 1/4 mile runs with all of my rides, even if I'm not making them into drag racers. So when I start modding I can see the real world results with little margin for error or dispute.
I'll be hitting my local drag strip with my RC F when I get back home. I still have the factory air filter installed.
It's still a nice dynograph though...

LCRSALES, what did you do to remove the CEL lights from running the headers and catless exhaust?
I think i am at the limit for the stock fuel system and the transmission capabilities. Nitrous being safe is only as safe as you make it. I have followed the footsteps of the ISF boys and have talked to 2 other RCF nitrous owners. They were using 200 shots. like i said i think the car's ability on stock fuel is 600 whp
