Oh dear...
Firstly, tho you was online and read my reply immediatley (and even posted a reply), so why wait till i was gone to bed before you replied in this way? So everyone could read your slating without a reply? (Esp as ive not been online on the weekend for about a month now so itd have a good few days of it) Thats pretty low i think, but anyhow, lets explain...

Basicly mate, the way YOU wrote your things about superchargers (and about how bad turbos are), you was writing it like it was fact, when in fact it was all wrong, and nothing more i hate about the internet is one person writes totaly false stuff as fact, and then a 100 people reads it as fact, and belives it, and tells a load more people, and so on, so i put the story straight, not trying to put you or anyone down, your a sound bloke, wasnt trying to be nasty...
Dont get me wrong, i dont know everythnig, far far faaaaaaaaaaaar from it, and would never think so, but i know what you were saying wasnt right, and only wrote in the way i did as the way you wrote what you did was making out it was fact, when it was infact fiction, lol

I wasnt taking the piss out of YOU for a start, dont take it to heart.
I have a level1 fuck all in jack shit mate. I got no qualifications in owt to do with cars, you got a lot more than me. Im no mechanic, but nor is a lot of tuners, lol, i just have a good mind for modifying force inducted cars for more power for some reason.
I not got loads of time to read about stuff, no offence but i prob got a lot more going on in my life than yourself, its just i learn these things. You always on here reading the same stuff as me, suprised you not learnt stuff too.

Oh matey
This comment was blatantly to try n call my bluff as you didnt expect me to have a similar graph. I didnt have a grpah last nite (tho ive already explained why a turbo is better than a s/c if you READ my posts properly
) but just as a total fluke i have now found (before i even read this thread today
) i found a comparison graph
Sorry about the quality, but its a screengrab...
This engine is supercharged AND turbo, just over 2litres again, twincam 16v. Huge turbo and a supercharger too. In a 10sec Manta.
Cant really compare torque as easy as its NM, but even comparing that cars low down power with a supercharger, to Rods with a huge turbo, a turbo nobody in their right mind would choose if they wanted supercharger performance, theres no much difference, lol.
And that car uses a huge turbo to give it the high RPM power as the s/c obv couldnt give it that to that extent.
If you want supercharger type performance, on a relativley low spec engine, youd run a GT28RS, which is half the size of a GT35, so really does have no lag at all, which is what i said all along.
Im sure i could find a GT28RS powergraph somewhere if you like...

If you READ my post i explained all that
I used rods car to show you even somthing with a huge laggy turbo isnt laggy these days. And also said if you used a smaller turbo (GT28RS) on a lowish spec engine, the same engine youd fit a s/c too, if the s/c would be about 250bhp, the GT28RS would prob be 300+ and far far greater low down power.

Drag racers use them as they always have, and more and more are changing over to turbos. Supercharger is good, ive said that, but nowhere near as good as a turbo. Maybe the rules/times they work to means they have no need for turbos, im not sure on the rules.
Busses and trucks with supercharged diesels? Where? The 50s?
Seriously mate, VERY few in modern times. Go look at 100s of modern busses and lorrys, oh looky, a fucking great turbo. Cant miss them on most HGV cabs as they visible from the outside so can see them while waiting next to them at the lights etc...
Actually, i dont know if the trains round by you are diesel or electric, but they diesel round here, and if you at the station and one of the smaller 2-3 car passenger things turns up, look down near the wheels where they exhausts come from... Ooh looky, a bloody great turbo again, lol.
Big in the US with braindead hicks, but i dunno if youve looked mate, but most big power yank V8 engines built for the past quite a few years are turbo, not s/c...
Its not big in Oz, they well into turbos. No bigger than here, or anywhere else.
Big in africa? Damn, africa, the pinnacle of modern technology
Like i said ALL ALONG, i love superchargers, i been telling my mate with an M3EVO that if he wants more power id get a big boost supercharger conversion rahter than a turbo as i think it suits the car better, the way it is. But its just the stuff you came out with (written like it was FACTO) was just not true, and if everyone reads untrue stuff that they think is fact, they belive it, and next thing you know everyone belives summat thats not tue.
Like "wastegate chatter"
