For those who asked.

I finally took the time and did it.

Here it is...

Brief Summary

From 2700 - 6900 rpm averages:

HP: 142.43
TQ: 156.40

For a true SVT perspective
After Secondary Activation: (3500-6900)

HP: 153.52
TQ: 155.06

A better perspective yet is the average power in the shifting powerband. (5000-6900)

HP: 175.4
TQ: 155.4

Here is the File

Up late too I see, thanks for posting the file.

Kinda & no problem...

oh didn't realize you had them?

Demon what does your air fuel look like when your secondaries open? That is a pretty sharp transition in your chart. When I had lousy exhaust the air fuel would dip rich at IMRC and with my new one, it does the opposite, it peaks lean at IMRC. Just curious to see what your does.

It goes lean!!! Right before, during and after the IMRC point it is leaner than normal.

I tuned it out with the S-AFC. The kick is smooth now... Also the chip lowers the IMRC point and softens it (which sucks!!!) vs stock which changes the shape a bit...

I will most definitely be addressing the IMRC point and spark advance before it. Like will enough advance (over stock anyway) help offset no secondaries... It's not that your are NOT still using the long runners, just only "half" effectively getting there benefits...

Need to get to the dyno for some testing soon...

DemonSVT... how much $ did you put in your car. I got a custom exhaust, kkm true rev induction and a superchip and I got 181 at the wheels. You got 7 more hp than me and threw down some mad cash.

You will never find out his mods. I go to his house and he won't let me know what's done to his car. The only things visible are the BAT intake pipe and the 9" K&N. The other thing that is visible is the SAFC. Oh yeah and custom exhaust. He won't tell you mods. So don't ask.

A lot less than anyone thinks.

Most of my mods I did myself.

Chip, MAF, K&N (KKM used in dyno), BAT pipe, Exhaust parts (I put it together myself), S-AFC (not used in that dyno BTW) = ~$1100 ($800 without S-AFC)

So even at that $1100 I have more power in the engine due to the S-AFC and K&N vs KKM. (which imploded at dyno, but that's another story - you should see the dyno graph from that one!)

Another $300 or so in aftermarket non-HP parts. (B&M, Aussie bar, poly bushings, etc)

I have maybe $200 in various future parts & pieces laying around.
I'm stingy... Buy low, modify and make high HP That's the plan anyway

Everything else I made or modded myself for pennies on the dollar. (or free) Even the mods I bought I modified a little for the most part...

I would really love to see a dyno graph of your SVT. What type of torque? How do the graphs look?
Sounds like it's running pretty well...
