Default My Stage 2/SST dyno

Just thought I would share my recent dyno:



Since I am still using the stock exhaust manifold I was trying to keep it as close to 19psi as I could but it was hitting closer to 20 on the drive to the dyno. It was not PCM controlled boost, just a line straight from the turbo to the WGA. My current "power" mods are:
SST
Stage 2, no toys
AGP WGA
Maxxfab 3" DP/Mopar cat-back
QW FMIC
ported stock intake manifold and throttle body
K and N drop-in
MSD wires/NGK 4306 plugs
and.....I think that's it.

The dyno plot from November of last year was done with almost the same mods as above. Only differences were, in November I was running PCM controlled boost with stage 2 WGA, no SST (obviously), and had an Iceman CAI. I was happy not only for my peak numbers to go from 282hp/299tq to 310hp/324tq but also because as my rpms climbed so did my power! There are parts in the graph that show a 45+hp gain. I forgot to tell the dyno operator to take it to the stage 2 6500 rpm redline oh well. lol Considering I was running a VERY conservative 10.8-11:1 a/f ratio I am very happy with my numbers.

WOW, was this with HOM? These turbo really do make a shit load of power. Thats like 40whp more than my S2/SST dyno...hum....maybe I got a bad turbo or something

Great numbers either way

Oops, I forgot to mention, stage 2 no toys. Oh yeah, in case anyone is wondering, these are SAE corrected numbers.

yeah, I noticed. This is why your numbers are so high.

your SAE correction is from 1.19 to 1.23.

Which means your PRE SST (stock turbo) numbers would have been like 235whp UNCORRECTED.

and SST would have been like 250-255whp UNCORRECTED.

so you REALLY gained like 20-25whp peak.

Im sure your location plays a part in these high SAE corrections.

No, I guess you don't understand the point of the correction factor. It makes it a "all things being equal you would make this much..." type of thing. Obviously the conditions differed from November til now which is why the correction factor varies. Look at the temp alone, it differed from 56 to 82. It is not like these were back to back runs but yet somehow the correction factor changed.

Correction factor takes more then just temps into consideration. But SAE correction is the only way to get consistant numbers from the same dyno.

Great numbers and with a tune or a manifold on the car you would have seen even better results. Not a bad start.

I know it takes more then temp into consideration, I was just using that as an example since it was printed on the graph. You are right, I definitely need an exhaust mani.......want to donate one to my cause?

You wish, but I will do the $85 scroll work for you to help with those EGT's. No matter how you look at it we have yet another SST into the 300 WHP group and looks like you made 300 WHP at redline, fantastic!

Yeah, huge difference in power from the stocker, just about a 50hp gain at redline.

Alright, this just makes me want one so damn bad but I have to resist for a little bit longer. Very nice curve!

At approx 4500' above sea level, a Dynojet will apply a correction factor of 1.15-1.18 (your case a bit higher) which is optimistic for a turbo engine that is designed to compensate for high altitude conditions (to a point, at least). I suspect that the raw numbers are overstated by 10-12%. But the % difference between the pre and post SST runs is perfectly valid. Just the raw numbers are a bit skewed.
