My CTS-V build

We're building a direct port nitrous setup just like this one (identical)

Modifying the 4.5" GeForce intake to make a new coolant resevoir


Coolant resevoir removed to make room for ProEFI and stock ECU mount and cover. Cover was made to hide ProEFI from tech as I'm "stock" to qualify for 10 ET











ProEFI ecu installed in passenger side of engine bay with cover removed and then installed

Car is mostly done, we were able to dyno it yesterday 12/8/14 at 900psi in the bottles so it was a bit rich with jetting but made 887HP on just the 2nd stage of nitrous (150 shot)
We also have a first stage of 75 shot that needs to be added as well. With the right bottle pressure and both stages this should be a 1000HP car.


2011 CTS-V Coupe 887HP on nitrous - BMR Built!

No plots? Wth

You've come along way since being the first to pop a Mazda MZR. Lol

I'll try and get the dyno plots soon.
Car will be on the dyno a ton more as we do more mods. :)

The 2.38 pulley, did that require any work on the snout, or is it a direct fit?  Where did you get it from.  Mine is still all stock, and am going to do a pulley, CAI, tune route.  Mid 11's is as fast as my wife needs to go.

It is the Lingenfelter  fully and yes we had to grind down the snout

Without grinding the snout, what do you recommend?
