 Turbo provide a free boost in poke as it's driven by the exhaust gases whereas a charger needs effort provided by the engine which is why they are less fuel efficient. Or at least that's what I was once told. ________________________________________ See the sheer power and might of the lesser known burrowing owl. |

I don't think the chargers are more performance oriented or the scoobs and evos would have them. But I don't know why they would choose one against the other.  ________________________________________ See the sheer power and might of the lesser known burrowing owl. |

I own a 306 and a mk4 golf and can tell anyone who asks what car id rather drive based on reliability and it aint a golf. VW are not the almighty people percieve them to be. bmw or audi is where im going next if i have to buy german. pug may have its little gremlins but its never truly let me down. the golf on the other hand nearly ruined me this summer with its countless problems. gotta wonder why i still own the bloody thing!!!  What's a load of bull? I never said the golf was more reliable I just said it's a better built car than a 306. sorry mate, wasnt intending on flaming you. I'll agree the golf's quality is better but its the build or maybe the fact its got more to it (& more to go wrong) than a 306 that lets its down. No worries mate im on your side ________________________________________ Team DiabloHighboost  |

Other thing to remember is those Subaru's and Impreza etc wouldnt have had a Rotrex as the techology wasnt even patented until the late 90's And most road cars use the older less efficent type of supercharge that works very differently, which is why you dont get the loud SC whine with a Rotrex. Dont forget the Koeniggsegg used CCR/CCX used two rotrex superchargers  http://en.wikipedia.org/wiki/Koenigsegg_CCXR But yeah But neither more more performance orientated than ther other. And both suit different applications better than the other too. ________________________________________ Ex- Phase 3 China GTi-6 T-Reg |

aaron6 wrote: Horsepower wise it more closely related to low boost. It went very similarly but the torque was awesome. Felt more like high boost but wasn't as quick. I just like the turbo delivery over the low boost charged ones. Silly boost is in a different class though. Which it should be, they have half as much power again. Hope that answers the question okay. Interesting  I would of loved to gone out in a turbo 6 i bet they do feel fast as the power and torque come in much earlier in the rev range. For me though i think highboost is perfect, while low boost has more than enough power to embarrass more expensive machinery and believe me i was shocked at the cars i was reeling in, i could name and shame loads  but what i would say is that it doesn't give you that wow factor that high boost does. I was always craving more power as i wanted that aggressive throw back in the seat experience , you get that with highboost & i dont think i will ever get bored of it. I know superboost is better again but it's also more money again I wouldn't want anymore power than i got now, its scary fast once the revs have built up quote from a friend `going out in your car is like being on oblivion at alton towers I would imagine a turbo conversion with 350+bhp would be insane ________________________________________ Team DiabloHighboost |

and also like i said if you map safely to enough boost you can run safely 350 hp and then if you want all the way up to 450+ by flicking a switch for a boost solenoid or turn the b**ch up on the boost controller________________________________________ |

Low boost still gives you that kickback in your seat feeling but just at higher revs, i would also say they pull much harder than a standard 6, i drove a standard one after getting mine low boosted and my god it felt dog slow compared to a charged one but your right though cars with loads of torque (especially diesels) do feel quicker than they actually are.________________________________________ Team DiabloHighboost |

Cant beat a turbo.But then gearboxes and clutches dont like turbos. |

From what i've read on here the smaller rotrex's start producing boost around 4k rpm, the boost is what makes the engine more efficient so produce more torque. Turbo's on the other hand arent linked to the crank speed at all so can produce boost much earlier in the rev range. BHP = Torque (lbs/ft) * Engine rpm / 5252 Using the above you can deduct that an engine making an example of 300lbs/ft at 3000 revs has the same bhp as a car that makes 150lbs/ft at 6000 revs. The earlier one being the turbo'd engine and the latter being a supercharged one. If the supercharger had a way to be spun faster at lower engine revs then it could produce boost earlier and increase the engine torque and power, but with the way most are fitted when the engine reached the top end of rpm the 'charger would be spinning too fast and probably s**t itself. The way round this would be some sort of CVT but i can't be bothered to then go into that. This is how i understand it anyway. ________________________________________ Goldie the track car. |

its because turbos deliver power in a spike and the boost increases as the engine revs.a supercharger is like increasing displacement and boost is linked to the revs in a more linear manner its easier to see when you compare two graphs. Its not a 6 thing its just how both technologies work. ________________________________________ Ex- Phase 3 China GTi-6 T-Reg |
