The Great Debate - Na Vs Turbo

[19914afc]

Gear ratios would play a big part too and where you lined them up side by side to race them, i.e qtr mile? circuit racing, ect no real way to define which would be better. Also as ke70dave said about NA cars with a decent amount of power will have a larger cam which doesn't make power till higher rpm.

Then you have cars like Honda with v-tech way to many variables for there to be a clear winner.

NA used to have its advantages, but I'm firmly of the belief technology has overcome those differences.

 

For instance, my JZX100 with VVTi and single turbo develops peak torque @1500rpm and holds a steady linear power curve all the way to 8 grand. No throttle delay at any point, no lag whatsoever. Mash pedal, scenery disappears.

 

 

 

This is why I can't drive 4AGE anymore. They're old, slow and only generate their measly 100kw at ludicrous rpm.

Sr20det that is all

 

haha touche'

 

HP makes the money, Torque wins the race!!

[Istartfires]

Looks like I'll put a sr20det in my rolla then. Yeeha

The LS2 + stroked VZ ute at work has the biggest cam available from crow, it does sweet f@$k all under 4500rpm but still makes 450 - 500hp at the wheels, if you were to get the same car, same engine but put a smaller cam in it and 2 relatively small turbo's (gt28rs etc) and it was tuned to the same power output then I reckon the TT would walk all over the N/A the the power curve would be lower.

 

Just comes down to the engine set up.

Mmmmmmmm VVTi 1J. I love that car.

Agree with Jarad regarding the Chaser's power.

 

I don't think I'll ever go back to an N/A vehicle again after getting my Chaser.

 

The look on people's faces when my RWD Camry smashes them is priceless. :D

 

Definitely agree with the linear power curve, its a solid line all the way to redline, no drop offs in power, no lag due to the VVTi and its a single turbo from the factory.

A turbo would 9/10 make more torque. I love turbo's they are awesome.

 

But for my long term project I've been looking at a 434 or 7.1 litre n/a v8 that makes 725hp at the fly. But it's 20k for the complete drop in engine. I could just go get a 351 and throw on a gt4202 and make the power easier and cheaper with more torque and potential for a lot more :)

one word boys 'TURBO' end of story and descusion . My reason becuse there fully sick bro :D

[Boosted]

It used to be (probably 5-10yrs ago) turbo's came on with a rush and were dogs off boost.

Advancements in engine technology have made it possible to have a decent compression ratio so the motor still pulls alright off boost and then change the cam timing so it will take a bunch of boost higher in the rev range.

For the same engine capacity and given an unlimited budget, the turbo will spool up and walk away from your NA motor.

After that it comes down to running costs and that's even more debateable.

I'm just gunna leave this

 

 

And this

 

 

Right here.

[styler]

Well it has to be in the same car really for a fair comparision,

I agree the most important factor is the curve theory which is

area under the curve and the curve shape ie powerband as it will differ

in delivery especially if the two make the same peak power

which results in a different driving experience for drag/track/rally etc...

 

Also consider the torque curves are probably different as well but for

arguments sake you could say they were the same but I would put my money

on the turbo at a guess not sure entirely...

 

I think the more worked an NA motor is the more it approaches turbo characteristics

with being unresponsive until the powerband kicks in hard and the more responsive a turbo

setup the more it approches NA characteristics of being responsive and early smooth

powerband through the range so it actually depends on how much you have worked each motor to get

the same peak HP reading as to the engines power delivery characteristics

 

Getting serious power out of NA can be a dog and its starts to get undriveable wheresas

turbo can be a compromise and quite sedate off boost and then serious on boost, and turbo

is much easier and cheaper and more common to do with popular DIY bolt ons.

So at the end of the day if it's the same car, same engine, same gearbox but with the only difference being is that one is NA and the other is turbo is that the result would be totally dependant on how the engines have been setup and where they make the power and torque.......It has nothing to do with how cool turbo's are or whatever car you bring into this as from the original post it was always the same car same engine.

 

Cheers for your responses guys.
