Drove a Vector ss...own a Linear ss

[shadow80]

Drove a Vector priced at 37.2K today...i own a linear with all options...the biggest difference i found was in the power delivery..my car has a quick immediate surge of power/torque...the vecter has more of a build up to power...felt like a dog on the low end of the band then at 2500rpm..power hit and hit fast...i swear my foot was flat to the floor on the vector till the rpms were at 2500..i paid considerably less for my car and i would not pay 5-7k more for a vector...my car is bl/char, touring, driver, launch, heated seats. Anyone experience the difference in power...btw..this is my first post..have owned my saab 93 ss since 10/02...ps..the little i listened to the stereo in the vector did not convince me that the 300w 13 speaker set up is considerably better then the one in my linear-150w 7 speaker set up..

I agree about the power delivery. I own an Aero (US Vector 210 BHP) and th turbo does jack until 2500rpm and then you get the kick in the pants. First gear to second is a bit strange, and leaves a bit of a lag unles you take first to the redline. Main thing with the power is the acceleration from 50-90mph, wow!

The 300w sound system is improving with time. I think the speakers need loosening up and it takes a while for this to happen. Also, there are software upgrades for the system supposedly on the way that will improve the sound.

first and second I think, correct me if i'm wrong, boost limited to reduce the torque at the wheels, the big difference between the 2 engines is the at speed acceleration. The 210hp will easily run and hide from the 175hp engined car. So to reiterate a point don't judge the cars performance by the fist 2 gears, rolling from 40mph its pretty formidable.

the differences you say you felt in how they built power could be attributed to the differences in the turbos.

Technically they're the same engine. One has a low-pressure Garrett turbo, the other a high-pressure Mitsubishi. High pressure, I assume (I'm no expert), means more exhaust needs to collect before it gives a burst to the engine, which would explain the higher revs necessary. I also assume that the engine management system knows this so runs at higher rpms in higher gears so you can take advantage of the turbo.

The diameter of the Mitsu turbo is > than the Garrett turbo so it can send more air to the engine => more power. Because of this increased diameter it needs more exchaust gas speed to drive the turbine, I would think. So, it is more like a traditional turbo engine.

Any ideas if you can chip the 1.8t and 2.0t engines?

avemave hit the nail squarely on the head. good technical info.

Hah, well, they both work off the same principle, one isn't more of a traditional turbo than the other - just that the earlier turbos generally had a lot of lag because they were wanted more boost.

I think Abbott has a chip for the 2.0t to boost the output to 200+. I stopped following it awhile ago tho (not worth it in a lease - I'm happy with the output and distribution as is).
