Tuned the car on the dyno today and very impressed with the results. Unfortunately, I got a boost leak and had to call it a day. I was hoping for high 700s, maybe 800hp. Will be going back again once I have sorted my intercooler piping.

 

Videos to follow soon.

Nice result :)

 

Won't the cams be a restrictive factor for your goals?

 

I should be able to easily get into the 700s on stock cams, but not sure if I can get 800. I'm confident on a 6766 I wouldn't be able to (vpower) on stock cams, but on a 6870 it might be possible. I guess will see... That said, GSC S1 cams are on my to do list.

Don't you have another 1500rpm in there? That seems a low rev limit and the power would at least level out and keep you in the power band for the next gear change.

 

The car revs to 7,200, but not sure why the guy at the dyno didn't rev to the end. :rolleyes:

 

I will update the post once I go back with higher boost and hopefully redline RPM. I'm curious myself to see how much power drops off (stock cams)
