I bought my Evo 9 MR 3 months ago after the dealer shown me the ability of the car. He actually scare the hell out of me by making a sharp right turn at 45 mph and a friend of mine was sitting and the back. However, I was trying to duplicate his driving technique but no success. I have tried to go like 40 mph, stepped on the brake, downshifted to 2nd gear, and floor the gas. Am I doing it right? The dealer was showing me on the standard IX and not the MR I bought. Could that be one of the reason why he can and I could not? Can anyone give me a good technique to make sharp turns at the highest speed without getting killed? Also, how fast were you able to do that with your EVO 8 or 9 ? Thanks!

 

handbrake turn ;-)

 

^ right and land on your roof. Take your time and learn the limits of yourself and your car. Oh yea, and take it to the track.

 

When you say 45mph,are you saying that's the minimum speed of the car in the turn (apex speed?). I haven't tried it myself (at that particular speed and I'm not sure how 'sharp' your sharp turn is) but normally, if you go quite agressive on the brakes, get a lot of weight to the front, shift down normally, turn the wheel quite quickly and as the car begins to turn, pull the handbrake. This will lock the rears and whip then round. Make sure you keep your thumb on the button on the hand brake and make sure you release the handbrake once the rear's come round sufficiently. Well, that's the theory. Practice obviously in car parks and such like.

 

smooth = fast. while abrupt turns may feel faster, the actual time through a sector is much quicker if you're smooth in all of your inputs. take it to a driving school and learn the car and what it can (and can't do).

to do a square corner at high speed (if I'm out playing or on a dirt/gravel surface on my friend's farm) I turn away, brake/turn-in, throttle and LFB to make the car rotate. I use a similar technique with the rally car on stage.

 

^ +10000 I wouldn't use the left foot brake though, but that's just me.

 

It's pretty much useless to apply one mph speed to any "sharp" 90' corner. The surface type and conditions matter, one 90' at one place would be much different than another one a block away. It always drives me nuts to hear someone say "well my car can take a xxx corner at xxxmph" I have taken 90 and sharper corners at 50mph, and some at 38mph..

From what you describe (brake, downshift, throttle) you might actually be inducing an early throttle-on understeer by going full throttle too early.

The real answer is go autocross it, learn to take all kinds of different corners, then when some salesman trys to show you something, you can comment on how bad he did it, instead of trying to replicate bad habits.

I've taken a 75-degree corner at about 80 mph.


Seriously, if you're talking steady state cornering, it's not the angle that's interesting, it's the radius of curvature. In a circle (skid pad configuration), that's the radius of the circle.

At 1.0 lateral Gs, it turns out that you can do a 465 ft radius corner at 83 mph. Which actually fits really well with the corner I was talking about above (turn 10 at Summit Point Raceway). The main part of the corner has a 465 ft radius of curvature, and so my speed of 80 mph would correspond to about 0.92 G of lateral acceleration.


For those interested, the formula is: V = Sqrt(RG) x 3.867.

Where V is the corner speed in MPH, R is the radius of the curve in feet, and G is the lateral acceleration in Gs.


For a typical 90-degree right hand turn on the street from one 40 ft (3-lane) wide road onto a perpendicular 40 ft (3-lane) wide road, assuming that you go left edge to left edge and apex perfectly, the radius of curvature will be about 137 ft. At 1 G of acceleration, you can take that corner at 45 MPH, but you're going to use every inch of road to get it done.

 

This thread made me laugh

 

for some reason why do i get the feeling we are going to be seeing another " I wrecked my car" thread in the future. come on lets keep this off public streets. if your interested in autocross go to a track day and have fun and safe.

 

Yeah, I guess I should point out that when I said,

it should be clear that 1 G of sustained lateral acceleration is probably impossible on a stock Evo, and is really pushing hard even on an Evo with suspension mods and sticky tires. And pushing hard and using every inch of road -- save it for the track. Bad things happen on the street when you have no margin for error.

 

Stole the words out of my mouth, floor it let the awd pull you through


Try to keep it on the track though

 

depends how wide your lane is.

 

Thanks for all your opinions & answers. I have got a family & my GG 9 MR is also considered part of my family too since the GG 9 MR is the one that our family feed the most. I won't get anyone of my family hurt.

The Capissed-tal & StevenCrap Mitsu dealerships in Silicon Valley - California have lots eith crazy or test drive to the extreme sales reps. Everytime I brought my car in for service I always hear turbo PUSHHHHH from the BOV & tire noise & smell at the surrounding public road. They are dangerously promoting their EVOs to the customers all the time. They also allow their customers do the same.

The only thing that impressed me from the dealership was that one 90 degree turn @ 45mph without getting the tired skid and just like if the Evo 9 STD IX was on the rail. That kind of go-kart corner performance is what made me traded in my old 2002 lancer. To me, cornering a car is more important than carrying horses due to high gas price on 91 octane (which is still around $3.81 per gallon as of today @ Shell).

The other question that I have is since there were a total of 3 person in the car at the time of promoting the cornering performance by the sale rep @ high speed (45mph), do you guys thing the sales rep was able to make that sharp 90 degree turn was because of the gross weight (3 guys + 1 car) holding the road better when heavier?

 

No.

It is possible in some circumstances to make a car corner a little better by adding weight -- but not the case you're talking about. The extra weight is significantly above both the center of mass and the roll center of the car, meaning that the car will experience more body roll when cornering. Assuming that the tire pressures and camber of the car are anywhere in the general ballpark of "normal", adding passengers will decrease maximum cornering speed.
