ZL1 Pulley & Tune Projected HP/TQ?
Just thinking out loud.
Pulley, tune, long tubes how much are they leaving on the table for us to play with on the ZL1? How much more will be able to get out of the LSA by upping the boost and getting the engine to breathe better? |

I'm guessing by looking at the lsa in the CTS-V that with pulleys, tune, exhaust you should be able to make 550+ to the wheels. Add a cam and larger injectors to that and you will easily be 600+

Best I can tell you are only hp limited by $$$ and how much risk you are willing to take before detonation occurs to the destruction of engine internals.
Trust me I am no export on the matter but my investigatons would tend to show that once you begin pushing 700 RWHP, some serious consideration should be given to race fuel which is consistent in octane and contaminant free. Additonally, race fuel allows the tuner flexibility to tweak some fine points providing additional protection against detonation. Chew up the meat and spit out the bones. |

I think you can go up about 3psi without changing much. headers and intake are not hard.
So I mean pumping the car up to 625-650bhp should not be hard or too expensive and could probbbaly be done with exhaust intake or pulley and tune. I read some posts on CTS-v forums adding longtubes and pulley sometimes people did not end up with the same boost numbers as without.

As long as you deal with a place that understands you whole mod list I am sure this is a non issue. I don't think I will go near as far as you are going. I would like to get the strait line speed back to the Z06 I am selling to buy this car though. My wife will get angry at me if my penis shrinks in size cause my new car is slower than my old car.

so, what are we looking at if we just do the pulley/tune?
Or is this something y'all would not recommend? |
