Hello I have a 2011 Mustang 3.7 V6 and thought about its tuning, because I'm a fan of racing on the 1/4mile . Please dont suggest me to buy a V8, this topic refers only to the V6 and its tuning capabilities. I wonder what are the possibilities of the engine 3.7 V6. Previously I had a 4.6 V8 GT with the Saleens supercharger on Stage 4 upgraded to 580 HP, even if this 4.6 V8 engine doesnt have forged pistons .. 2011 3.7 V6 engine is much lighter with these forged cranks and pistons, so my question is whether power can also be increased to around 500 - 550HP(450-470rwhp)? My second question is: what is more reasonable to choose: a supercharger or nitro or even supercharger + nitro? Please notice that cost is a quite important factor for me. Otherwise I would of bought myself a Shelby GT500. Supercharger loads the engine and increases the weight on the front of the car, but the increase of the power is stable and same from the beginning where Nitro isnt increasing weight on the front, but provides engine with the sudden shock at about 4500rpm. Can be that destructive for the engine? Some Nitro kits are also with the progressive gain of power, where the dose of nitro is increased in the next few seconds, that is, the engine suddenly gets not 100 or even 200 HP impact on the pistons, but the power is gradually being raised. Is such a set a better solution? And my 3rd question is: How efficient is the new fuel pump in 2011 V6 model? How is the fuel system designed? Does it have a return of the fuel? How can I improve the performance of the pump? Are there any better/simpler ways or BAP is still the best solution? maybe procharger (procharger.com/supercharger/blog/?p=210) + Nitro direct port shot 75-90HP ? Thank you in advance for your answers, especially the experts.
