I have been thinking about this now and I honestly can’t find an answer, so I would like some opinions....
Why do people prefer N/A cars to turbo, after seeing many highly tuned N/A cars, it seems that as with turbo's the power is quite high up the rev range, I mean you have to keep up the revs to use the power right, well a good driver in a turbo car would be doing the same thing to eliminate lag
.... So why not just opt for a turbo,
It’s certainly a lot cheaper to get the power from a turbo, also easier to tune
Remember im only talking about modified N/A engines here
Horses for courses. That's why Bugatti Veryon will never be as good to some people as Macca F1 (me, for one) because it needs four turbos to shave 0.3 of a second off its 0-60 time.
Turbo rush is massively addictive, but then a good N/A engine is so much fun because you have to make the effort of going to 7000rpm+ to get the most out of them. Although nothing sings like a good V6 or V8...
I think it would be an interesting project to twin-turbo an engine with proper cubes.
Say a dodge viper. enough cubes, enough cylinders(but not too many), now *that* would be a torquey/revvy pushrod, eh?
steering wheel on the wrong side of the road though:beer:
That was the same dilemma as in the Group B rally era. (Proper cars, like). Audi Quattro and Peugeot 205 T16 ruled the roost with mega-boost motors, but the Metro 6R4 went for cubes. And lost out really. But then today's WRC cars are quicker over the same stages with 250bhp less just down to tyres and brakes.
Proper bonkers.
the original V10 was turbo charged by an outside company. made around 800 bhp as far as i can remember. one had one turbo as there was no room for a second. bit tight for room once the intercooler and other assorted stuff was under that bonnet
Yeah, motorsport's a tricky one, because cost, regulations and all sorts of factors get involved. The best turbo F1 cars made 1500bhp from 1.5 litres (can you imagine 1500 bhp in 500kg?) and then they banned them, but F1 rules are all about politics.Indy cars use light pressure turbos and alcohol fuel. But in drag racing the restrictions are pretty much down to how much cash you have. IIRC superchargers are more popular than turbos in drag racing, but then methanol is more popular than Optimax!
1) temps. Yeah a problem. A few ways to sort this though.
2) Lag isn't a big a problem as people think. Esp. when your already on the move you can select a low gear and have no lag.
and if I manage to upload some of the callys starting at the pod you will see some don't have a problem from a start either.
3) Well I love having all the torque applied in one lump, gives you are real . Esp. when you have a 4x4 and apply all the torque while entering a corner. Big Big or half way round a roundabout.
But at the same time can understand that a smooth torque curve is a more plesent car to drive around in and that turbo cars can be tiresome with all that bloody torque when you are trying to relax.
Odders. Don't get to disapointed with the drive in your mates cav turbo. If it's standard they aren't alot of fun. You need at least 250bhp or running 1 bar before they start to impress.
Superchargers - Give you a smooth torque curve. But I don't know. They lack something I can't put my finger on.
turbos were banned in F1 because all the poorer teams didnt and couldnt afford to run those engines. it was done to try and level the playing field, so much for that
The overall reason turbos were banned was that they were too powerful (and dangerous in competition). They tried limiting the maximum boost, but it's easy to cheat on that one (if you know how)
In any case they wanted to push technology into higher-revving engines, not forced induction.
There is a competition in the States where they only allow a couple of psi boost. The amount of power they make is unbelievable (for those who think boost is good). Only snag is that they only work efficiently in one part of the rev range.:beer:
Lol at people who claim there's no lag at high revs in a turbo car. they've obviously never driven a TB'd car! the response is just so quick. Which certainly isn't the case in any turbo's I've driven (2 vx turbo's and a MR2 turbo, and a few diesels lmao)
No competition tbh when it comes to drivability. NA all the way. predictible and very controlable.
Amusing how some people say how great turbo's are in a 4x4 cars. I'd prefer rwd myself.
You're confusing 'lag' with 'throttle response'
Most people think it's the same thing, but it ain't. They're related though.
Lag is a fact of life for turbos, but it can be reduced in many ways (not eliminated though)
Crappy throttle response is another fact of life for turbos, just look where the LET has the AFM in relation to the throttle valve. That huge air column going through the hot pipes and the intercooler is compressible, too!
Then there's *boost threshold*, commonly mistaken as 'lag' once again. It's different.
Bottom line is that if you want razor-sharp throttle response, you don't go for a turbo. Same way as you don't go for web-based applications if you want quick response - you want the stuff LOCALLY on your HD.
But if you want throttle response so sharp that it hurts, then you also want a seriously light car as well, so the suspension and brakes respond as fast.
Turbos are better suited to 1-1.5 ton lardmobiles that will never feel sharp anyway, so they can compensate with silly horsepower:beer:
I think Gary, MattJ, 0ddball and region17c will be along in a minute to confirm this is true.
Of course I expect some of the turbo boys will vehemently deny this, but as I'm sure you know denial is the always the biggest give away of a closet nudger.
- oh the majority of the other reasons already given also point towards NA being better, but obviously my reason is the most important and factualy correct.
