Arent turbos sluggish when trying to drive off boost??

Post by Vindezal »

Tis one of the reasons I didnt go for this model as the N/a drives better as a daily drive i.e on pick up. :wink:

But! I cant be sure. is the turbo bit slugish if driving normally?

Boost = £££££

depends what you mean by sluggish. It not exactly quick with the lower compression ratio but since boost is starting just over 2k coming on strong by 2.5k and full on by 3k its not like its a problem.

must admit I like town driving in mine just keeping the throttle easy and no boost, if you want boost its like a foot jab away. Not a problem

I think most of this forum would argue that the turbo Model isn't sluggish by any means!
I've owned both n/a's and a turbo model, The n/a for me has the looks but gets trounced power-wise by today’s modern cars.

The turbo will always be a legendary drive...

what are you jibbering on about? turbo and NA drive pretty similar off boost as i found on the kent run, turbo seems to pull slightly better but then it hits 3k RPM and it's bye bye NA!

wouldn't have an NA mainly because i hate the sound of the NA 2 litre, sounds to weak and gutless much prefere the noise of the MR2 turbo, i think a MK1 NA sounds better than the MK2 NA.

just my opinion though mind :mrgreen:

Since putting together my normally aspirated rev 3 race car I'm increasingly impressed at just how good it is. Thing is, you really have to put your foot down and keep it there - use the whole rev range! An induction kit such as the K&N 57i or Apexi will really make a difference to the noise as you can hear the ACIS (it is ACIS at rev 3 isn't it) kicking in.

I find the turbo really responsive when driving everyday. You only to need to stick your foot down and the power's there, it can light the rear wheels in the wet from around 2500rpm!
With an NA you need to scream it to get the power out of it, with a turbo you get a big chunk of your torque/power in the mid-range, and since I don't spend much time under 2k rpm in any situation, I think it drives great.
More responsive than other turbo cars I've owned/driven.
Just my 2p!! :mrgreen:

Tim, you stirring again ;) ?

There is some Turbo lag on the Turbo, but the 3S-GTE engine has a very nice and progressive boost build eg unlike Cossies. Off boost its got similar power to the NA:

"A NA is like a Turbo with never ending turbo lag" :D

Firstly you have to drive the car properly. A turbo isnt some magic wand meaning any gear any speed acceleration. If you try and put your foot down in 5th at 30 mph then yes it will take some time to get going. But you cant tell me that if you did this in your NA you wouldnt be waiting an age for the engine to come on cam?

I have a huge turbo on mine and even on light throttle and keeping it below 4k it spools up very easily.

Turbo lag is an urban myth, change down a gear to get the car into its proper power band.

i get turbo lag if im in a stupid gear like 4th at 30mph.
its impossible to say youd rather an NA for this reason.
im always in the 2.5k-3k rev range when plodding about, if i need to speed up, turbo is instant and pull to full boost by 3.5-4k close to where you have max torque.
however, if im in a higher gear, say 3rd at 30, 2k rpm or there abouts, max boost comes in at 2.5-3.5k rpm.

na max torque and power curves are much higher.

Why would an NA MR2 be quicker than a turbo MR2 around the twisties? :?

Surely if they were both standard, the handling would be identical and when driving hard you don't suffer turbo lag because you're in the right gear and the right rev range all the time.
So the only difference is the tubby would kill the NA pulling between bends and on straight bits. :wink:

exactly.
just like the nas need to be in the right rev range, so do tubbys, infact so do all cars.



just like on top gear when they had a evo FQ400 and some tiny town car.
they both were in 5th at 30mph, and the town car pulled away from the evo, until of course the evo started to boost!!!
pointless exercise really, as why on earth if you have an evo you would be doing 30 in 5th!

Thats because it has a big turbo.

We don't. Put your foot down at any thing from 2 k and you're off. The NA needs to rev it nuts off to get peak torque.

I don't think an NA will beat a tubby round a track. Sorry. Unless the driver of the tubby was a lame one. But give them to the stig or an experienced driver and they'd get the tubby round faster.

Because the NA is much more proggressive in the rev range. My NA with 16" advans (245 rear, 205 front) on standard suspension has surprised alot of people! a few tubby owners on here too =D> im sure one or two will speak up when they read this [-o< .
