Lightning on the Dyno

My wife took the Lightning to the a dynojet yesterday. She got some impressive yet hard to believe numbers. A stock lightning should dyno around 330HP and 425tq stock. The lightning has a steigmyer ported eaton, JLT cold air, LFP valve body, C&L elbow and plenum, and a 4lb blower pulley for a total of 12-14lbs of boost.
1st Pull-421hp and 593tq
2nd pull- 467hp and 644tq???
3rd pull- 442hp and 622tq

HP numbers seem about right for the modifications. Torque seems a bit high. It was 91 degrees and 8% humidty, but it was cloudy as heck in the pictures so I doubt it was 8%. Probably closer to 15-20%. Altitude is 4000ft. I will post the dyno sheets when I get them put up on my website. AF ratio was 10.6-11.2 on all three runs.

Heres the video done by a friend.

Excellent HP numbers! It's not uncommon for auto-trans vehicles to show the abnormally high torque spikes on a DynoJet as the converter slips. If you have a MustangDyne dyno or a Dynapak (both load bearing) you might be able to get a accurate torque reading. I'm sure it's in the 500's anyhow.

Ah, didnt even think about converter slippage! Ill check into that! Thanks!

It's torque mult by the convertor -- don't think for a minute the engine produces that. But...the TC does in fact multiply until it couples -- then you get the curve you see. A tight converter won't do that.

Anyway, the peak HP is incredible.

I wouldn't expect a stock converter to be doing any multiplication at 4000rpm, at least nothing significant. What's with the weird 200rpm wide 'bump' in the otherwise smooth curve? I don't have much dyno experience personally, but I haven't seen any narrow little bumps like that before on any other dyno sheets.

On the dynojet you see that 'flare' all the time on loose converters.

With the converter causing the spike, it reads 600+ on the torque. You have to scroll down the graph to see the real torque reading which was about 520-530. The truck is getting a 6lb lower and a new tune to go along with it today, then its going back on the dyno. The one problem is the throttle body is a big bottle neck now. My wife was able to improve .4 last weekend swapping on someone else's thorottle body. Just more reinforcement that building power is a package.

im having trouble making sense of those dyno sheets.shouldnt tq and hp "meet up" at 5250rpm?
