FINALLY WENT TO THE DYNO 433HP AND 509TRQ

[ddlopes]

So after resolving all the issues with my meth kit I finally took the car to do a few dyno pulls. The dyno was a Dynojet model 424 with linked rollers. I was able to run the car in 4th gear. The only issue I had was trying to turn off Advanced Traction Control. I held the button down for 5 seconds but nothing came up on the screen saying Advanced Traction Control off. So I just shut off the standard traction control. I did 3 pulls and the car laid down 433 hp and 509 trq. I was extremely excited with the numbers and I'll send Brad the logs to review. I'd also like to thank Brad for all his help. This was a PITA do to all the meth issues but he worked with me until everything was resolved. Thanks again Brad!!

Z what gear did you use on the dyno? I used 4th but couldn’t rev higher than 5900 rpms before it shift into 5th.

Mine was done in 3rd.  4th is 1:1 ... but at that point your pushing past 160mph simulated and mine got weird in higher RPMs,  we went to 3rd and adjusted the load and got my numbers that way.

Also your tune can switch ON/OFF down shifts manual mode.  mine is set to not down shift so we can dyno without being in automode.

Good numbers!

What are stock numbers at the wheels?

AFAIK the Dyno's were performed using which ever gear is closest to the 1:1 ratio,which on the SHO I believe that is 3rd gear pulls IIRC. Z

Here's the graphs...

Two questions. Do you have the logs for the power runs (I would be interested to see the boost vs. RPM compared to commanded boost vs. RPM - looks like there could be a boost spike at the peak number).

2nd. What is it with SAE correction/what is the actual correction factor used and conditions for the run? Some correction factors are more aggressive than others.

Nice! Id like to comment later but you could ask the dyno shop for the raw dyno file and then download winpep and view the dyno pulls with and without corrections and smoothing

That's awesome! Quite a bit of power you are pushing.

No.... never taken it to the track. But I think it would run low 12’s or really high 11’s

Wow nice! So funny SHO can do that on stock IC but trucks always swap theirs out.
Congratz!
