Because of the gearing, maximum longitudal g will occur in 1st geat.

Automonile magazine tested a non-X50 Tip Turbo and recorded a peak acceleration of 0.90 g. The stock six speed would do better than that.

 

So, it sounds like attaining 1G of forward acceleration is a possibility. Can anyone corroborate this?

 

It might be briefly obtained in first gear,
and sticky tires would help.

 

1g is a huge number. Not impossible, but HUGE. Maybe the 4wd makes a big difference here because getting 1g is near the limit of traction in many street tires so this would be impressive with a 2wd car, maybe not quite so diffiuclt in 4wd. If I had my system in, I could give you hard data.

 

Does anyone know how many negitive G's a Turbo can pull when an emergency stop is made, (like a quick stop from 100mph-0), if someone can give me initial speed, time, and weight of the car, I can calculate this number.

 

I got over 1g with my stage 4.

 

Tim (Colorchange) makes a very good point. The limit of adhesion will undoubtedly be the limiting factor. This should apply in ALL directions much like the numbers that get published for skid pad tests. Adhesion =friction force of tire on road =vertical load on tire x coefficient of friction. It is irrespective of direction.

So, it gets me thinking, wouldn't the perfect car be that which can induce 1g during acceleration, 1g during braking and 1g during lateral skidpad tests? It sure sounds like it.

Does anyone have hard data to compare the three directions of force?

 

Negitive 1 g is not that much, a person can handle between 20 and 30 some negitive G's, im sure that the turbo produces much more then negitive 1 G's when stoping.

Correct me if I am wrong but my understanding of the terminology of positive and negative g's doesn't generally apply to driving except in vertical roadway curves (hills and valleys). Positive and negative g's really pertain to flight wherein the blood pressure in the pilot's head is increased or decreased with g forces in the up or down direction relative to earth.

It was my understanding that positive g's are those that are additive with gravity. In other words a pilot goes into a dive and then pulls up hard. His apparent weight is some multiple of his real weight and the blood pressure in his head drops thereby inducing fainting (hence the proliferation of pressure suits).
Negative g's are those that are subtractive from gravity. 1 negative g results in weightlessness.

In lateral acceleration situations, such as a car accelerating or decelerating in a straight line or laterally accelerating or decelleratin around a curve (skidpad) they are all just lateral g forces. I recall some footage of Nasa tests on the rocket sled in the 50's wherein they tested the effects of rapid decelleration on the human body. I believe the guy experienced some ungodly force like 24 g's and his retinas partially detached from his optic nerve or something like that.

So after my little disertation, I agree with your point, just not the terminology.

I would still like to see some results form those that have these G devices to see what kind of real world numbers can be achieved in forward acceleration, braking deceleration and lateral acceleration.

 

The new Getech Pro is called the"GT2"

 

No, that is the Escort G TIMER they have a GT1 and GT2, Gtech is a diff. company...all the radar detector comps are making um now...saw a Bell the other day...

Oops, I messed up my terminology, but as you said, my point was that the Turbo should produce more than 1 (lateral) G when stoping.

 

just to give an idea...

a ride from earth surface to outer space is about 8G

 

Again lateral G force due to its perpendicularity to the axis connecting heart to brain.

 

Got a 4.09 with it.
