But is it better? 1200 can make power

 

With so few running the c38 on the S, hard to say. Don't have enough information, even less accurate information.

 

TTS uses the 91 with their race kit. I believe there's more torque that can be made over the n1200, and coming from the n1200 it will be interesting to evaluate the results once it's on the car just waiting for SOS or radium to get back to me with a rerun fuel kit so I can get on with it!

 

Hey...let me know what you hear from Radium if you would please. I need to go down this path too.

 

Will do my friend I just want to get everything all in one go and do it right, ONCE haha

 

Thank you Sir! Much appreciated!

 

Glad to see more dynos being posted up. Thank you.

Also we are offering the C38-91 upgrade with any Kraftwerks supercharger kit if anyone is interested.

 

What would the C38-91 do/allow? Would it just flow more CFM per RPM? If so would we need a better intercooler and piping then to see any gains at the same PSI?

 

You answered your own questions. Yes and yes. Unfortunately they don't offer this as a solution. You would need larger piping and intercooler.

I was told directly from Kraftwerks the C38-91 it doesn't nessicerily make more power as it just makes the same power in different places in the rpm band. The c38-81 makes more power on top end where the S's already make their power which is why I upped the rpm.
Like I said, my tune was super conservative. The fuel was very bad. We were having issues all day with fuel.. It was like a crappy 91 not even a good 91 so my luck it's like 87oc haha
You should see a gain in lower band power. The way they described it. It's like a seesaw pull it up on one side it lowers on the other side of the rpm band.
Now I don't know anything about getting more boost out of bigger piping and intercooler... I can attest to Skunk2/Kraftwerks customer service. Holy cow it's been great! Like incredible.. Helped me at every turn. Overnighted stuff. Just really great!
