Procharged C7
#1
Just finished my install.
Overall it was very simple, I went with the straight cut gears and louder bov. Still a little quiet for my liking..... Man is it fun to drive tho. In the down time waiting for parts I installed a dyno also....
Here's the dyno sheet I'll post install pics later.

So I was going over the dyno software and after entering all the correct settings for the area I am in ft above sea level (Mississauga, Canada just outside toronto) and the correct dyno drum inertia. The dyno sheet changed significantly.... Here's an updated one
This is still SAE and Smoothing 4
Under "Standard" Corrections it is 581.9whp/558.6tq Not sure what the actual difference in these setting is, if someone who uses a dyno more regularly could chime in that'd be great.

Uncorrected is what it actually put out, at the wheels, on that day, elevation, temp, etc. You rarely see these numbers on the internet
SAE corrected is what you would, in theory, make at a specific elevation, humidity, temp, etc. decided by the SAE. There's a long formula the SAE established to convert to 'corrected' numbers.
The idea is so that people can compare dyno sheets from different areas/times of the year and in theory get comparable results.
Somewhere in there you should see a correction factor which will tell you how much it's adding or subtracting based on the altitude, etc. that you put in
I've only seen 1 or 2 dyno sheets on the internet ever where SAE was lower than uncorrected. Usually people are above sea level, in hot shops, etc. so the correct numbers end up being higher. I saw a 1.33 correction factor once from someone at a high elevation. Dyno sheet was showing something close to 800rwhp. What was it actually at the wheel? 800 / 1.33 = 601rwhp

Ok so in this software I have an option for "None" sounds like that would be uncorrected.
Couldn't find the correction number. with it in setting None the numbers are 563.1whp/540.7tq
When posting dyno sheets and printing them out for customers, which setting should I be using?
None, Standard or SAE? I also have options for DIN, EEC, JIS or ISO 1585

Yeah none should be uncorrected. Not sure about the DIN/etc. options. I can look through some old sheets tomorrow and see what was used
581 / 563 = 1.03 correction factor, more or less. I'm not sure where it is in the software you're using

Ok sounds good thanks a lot. The unit is a Dynocom and the software is DynoComPutex.
They just released "Quantum" so I will be upgrading soon I just wanna get the hang of this thing first because this is supposed to be some new amazing updated stuff to phase out dynocomputex. Are those good numbers for a bolt on procharger with their basemap? I'm still waiting for HPTuners to show up so I can tune it

Ah ok, I'm thinking about a dynojet so might be different on what you're using..
I'm not very familiar with C7 #'s so can't really help there

Those corrected numbers are exactly what you should expect on a base Procharger set-up. I would go as far to assume it is a manual car as well with those numbers. Auto's dyno a little lower.

Very nice. SAE corrected numbers are most meaningful for comparisons, and thus is what people like to post.
Uncorrected numbers are good for tuners to see how much power is actually being put down to see how much "room" there is. For instance, I'm at high altitude, and while my SAE corrected number was 670rwhph, my uncorrected rwhp was 518rwhp on that very hot day. At sea level, my car would accelerate very differently.
Also, methanol is super easy to obtain, store, and use, so if you're looking to make a bunch of power, don't let the methanol requirement hold you back.

HpTuners finally arrived. Here are my final numbers
Next year will be meth, pulleys and headers. Will see if I can pull 800

Really nice car. Perfect street combo.

The cost was $9,000 CDN for the kit and I installed it in house at my shop, tuned it myself on the new dyno.
I have pulleys and meth sitting here waiting for summer time to be installed to squeeze even more power out of it.
Fuel economy is terrible but I haven't done any regular driving since I installed it, but who buys a v8 for fuel economy lol.

That is sick! Congrats to you; Im sure you will have some stories to share!
I was fortunate to purchase a brand new 2016 c7 in October and already "outgrowing" it; I was looking to spend in the $5k range. Perhaps outdoing the z06 isnt in the cards for me right now.
Thanks again for the info.
