| whats better for the uphill a turbo charger or a super or what about twins and a centrifugal supercharger
SO MANY OPTIONS | |

| I'd say either a twin turbo or a twin screw supercharger | |

| Based off what I know: Twin turbo >= Single turbo > Centrifugal supercharger > Twin-screw supercharger
Twins have less lag in real life but in Forza it's more like there's less "kick" since the torque delivers more linearly (when looking at power charts) but whether it's true or not doesn't really matter because it's virtually unnoticeable under 600hp. Personally I like to keep my car with the stock aspiration, one of my fastest cars is actually NA.
As for turbo vs supercharger, turbos weigh less and are capable of delivering more power so I don't see the benefits of installing a supercharger since "boost lag" is only apparent at 600+hp and sometimes even higher than that. Superchargers are just excess weight and can only be useful for installing in MRs to alter the weight distribution a bit. | |

| We all know whats best for forza but in terms of real life. There are two types of twins turbos, one where both turbo's are identical functioning as if one turbo, another setup with identical turbos with one gaining boost and the other compressing it further and other where one turbo is smaller than the other. The twin setup with a smaller and bigger turbo is typically the one with less lag.
Lag honestly depends on the design of the turbo and how big it is. The bigger the turbine, the longer it takes to spool up.

Wouldn't the small/large turbo combination be useful for cars with longer gear ratios or poor acceleration with a single turbo? | |

| Gear ratios should be tuned for the motor, not the other way around. Define "poor acceleration with a single turbo" lol To me that just sounds like the small ass turbo for a stock 1.8T volkwagen but who would want to twin turbo that? lol Twin turbo RX7 FD's and mk4 supras came with that setup. | |

| I define poor acceleration as in the car does not have good top end power or speed from the single turbo.
Me and my poor wording. | |

| Turbo's are meant for top end power in general. BTW when people refer to top end, they are talking about the last half the rev range where turbos makes more power. There are single turbo's that will easily make the same power as twins, but the dyno sheets will always show the difference of when full boost and torque comes in. | |

| You do have low end turbos, and mid-range turbos. So if turbochargers have more of a benefit, why do some cars behave better with superchargers? (Pre 1979 American muscle comes to mind) | |

| It's not that superchargers are better or worse than turbos they're just different ways of boosting engine power. They both have advantages and disadvantages. | |

| Turbochargers take time to build boost, "turbo lag" hence why they make more power in the top half of their rev range... Because they want instant torque the second they gun it, what better way to get that than adding a supercharger? | |

| There's also tri-turbo setups (Porsche and Volvo for now), Quad-turbos (Bugatti), and Combocharging/Multicharging (turbo + superchargers) used by Lancia in the Group B era I believe. | |

| I think the diesel m5 uses triturbos as well | |

| Nothing says power like shoving turbos into an engine.
Does anyone here prefer NA engines? | |

Does anyone here prefer NA engines? With a diesel engine, no. You need a turbo in that circumstance due to the lack of torque. But with a petrol engine, I would personally prefer a good NA engine over one with forced induction. If I did by a car with a forced induction method, I would go for something with a bi-turbo or twincharger setup; as both have the potential to lower lag. Especially the latter, as it would tend to use a supercharger for initial throttle response, which allows the turbo a chance to spool up. But as with anything, those setups do incur additional maintenance cost, and higher repair bills. | |

| I prefer NA engines, the power is more direct to the accelerator | |

| If both cars had the same amount of horsepower and torque, I would go with NA. Why wait for the power when it can come instantly? | |

| I love the battle in Initial D where Keisuke and the other girl (i forgot her name) battled with their fd's and Keisuke won because he tapped her just when her turbo kicked in i had a cargasm | |
