I have an update. The dyno test is partially completed.

1st Dyno (Baseline and Sae Corrected) 91 Octane Gas:
Truck is stock mechanically except for:
Mopar Connection Stage2 Flash
170 T Stat
Magnaflow CB
JMB CAI

Todays Results:

2nd Dyno (Sae Corrected) after adding these parts on 91 octane gas:
Mofo long tube headers
Mofo mids with cat delete
Roe TB

I don't have the chart with me but it was 30RWHP gain and 25 Torque gain.

3rd Dyno (Sae Corrected) after adding these parts on 91 octane gas:
SCT Tuner

We are going to do the 100 octane tune in the morning as we ran out of time. So far we know the SCT tune on pump gas with a little tuning from Chris based on the typical stage2 flash gained around 5 RWHP and 10 Torque. We will find out how much more power we will get on 100 octane unleaded race gas in the morning.

So who won? I guessed 454 whp

Nobody yet we have not done the final stage with 100 octane race gas. We will know tomorrow.

Here are some pics from today:

Video will be following after we're done. Chris explains the benefits of the SCT Tuner.

It's not too late to guess but your guess won't count towards the prize since you came in late. I think you will be really close.

Off to DC to complete the Dyno. Here is the video from yesterday:

I will post up the charts later but here are the final numbers on race gas:

460.74 RWHP
497.63 Torque

 

[SrtBrad]

461 rwhp

We have a winner.

IF YOU WANT TO KNOW, GO TO THE GTG @ AZ

 

[SrtBrad]

Here are the charts: (All Charts SAE Corrected)

Baseline: (91 Octane Unleaded Gas)
(DC 91 Tune, 170 T Stat, JMB CAI, and Magnaflow CB)

Second Dyno: (91 Octane Unleaded Gas)
Baseline plus Roe TB, Mofo long tube headers and mids.

Third Dyno: (91 Octane Unleaded Gas)
Baseline plus 2nd dyno additions and SCT Tuner with Chris custom tune:

Final Dyno: (105 Octane Unleaded Race Gas)
Baseline plus 2nd dyno addition and third dyno additions with 105 Octane Gas and custom tune by Chris:

I was not happy with the gain/loss of the last race tune with 105 octane gas. I was able to only get 3 RWHP gain compared to 91 tune with a 4 torque loss.:dontknow:

Is the octane too high? Is the compression of our engines to low? I just don't understand how 14 octane increase in gas doesn't translate to at least 15-20 RWHP. Anybody got any ideas?

I wonder how much of that 30 wheel was cat delete and how much was the longtubes?
