Review: 2015 Megane RS275 Trophy-R + On-Board Video

Yes 2WD you will feel more brutality and torque *COUGHS* steer *COUGHS*, definitely need a LSD installed
Once you got used to it, just be careful

 

[RENESIS VIII]

If both cars of same power, one delivering to 2WD and one to AWD, the one with 2WD will be wild as all power going to these two wheels only. STi are brutal in acceleration but with control, but if power deliver only to the two front wheel it will spin and pull. That was the feeling when I first got my VR back after transplant. First month or so have to be careful powering out from T junction.....lol
Yes, jam here and there, but I know the side routes, if not there is always waze .....hhahhahah

2 days ago, tyre shop boss told me about his experiences in modding 4G63T engine in Wira and Perdana. He told me if want to play with such engines, need jaga driveshaft when it comes with LSD because easy kong. I ask why he said because they are originally designed for 4WD use, so when lock gearbox to 2WD, there will be more stress on driveshaft. True about this?

Even without LSD also, yup it will stress the driveshaft for sure

I sat on a EG hatch with B18C (not type R) before and when the driver shifts, I can't even hold myself properly to my seat. My whole body just lurch forward towards the dashboard although I tried avoid that.

A passenger that is lunging too abruptly forwards in between shifts equates to bad manual shifting driver

I read his post again and yes should not go forward. My colleague when he sat in my car and when I accelerate he cannot reach the dashboard because the force pushing him onto the seats.....hhahahha

Mine without LSD so far okay, anyway 16 years already sure got replace before.....

Actually I only lunge forward when he release his throttle during hard acceleration and engaging the clutch for the next gear. Otherwise when he is driving normally, everything is fine.

Yours mostly still stock isn't it? The tyre guy said if use 4G63T, better remain stock or mod only minor things to ensure reliability.

But when change gear should not lunge forward....

Yes, is 4G63T but welded to run 2WD mah! so all power goes to two front wheels

You should use the AWD drive train but then decouple the front and make it RWD, that would be even more wild! You'll turn your VR into a drift machine!

I take back my statement to be fair since I have no idea how severe it was.

It's just when I read what you described, i thought it was pretty bad. i've seen too many drivers not realizing this and have permanently adopted the wrong technique. Transition between shifts is inevitable but can be made smoother. It is up to a driver to ensure his / her passengers feel pleasant.

My advice is, the faster and harder you go, the quicker the shifts need to be. Likewise, when driving slow or when cruising, shifts can be slower. It's not so much the shift knob but the footwork mostly

 

[6UE5t]

I think my manual shifting skill is pretty shitty now already!
Too long driving auto and only once a year for a few weeks driving manual.

Well, the feeling is like when he is accelerating, I am leaning my back on the seat. When he lets go of the throttle, you the kind of feel like the acceleration g force is gone and you are like still moving forward? Like when you are braking too abruptly and you find yourself lunging forward. Something like that but less severe than sudden emergency braking.

But still stock ma, not so much stress maybe? The tyre guy was saying if you are running 2WD and still doing intense mod like larger intercooler, changing pistons, changing into larger turbo, driveshaft sure very easy kong.

I think the lunging is probably due to the sudden lost of acceleration when he releases the throttle.

Quicker shifting while going fast is to prevent speed lost and rpm from dropping too much isn't it? Shifting smoothly is like trying to balance out your foot timing with the clutch and accelerator pedal. I always will try to time them simultaneously to be like when one pedal is down, the other will be up.

Good manual transmission drivers can minimize this sensation. The rate in which the car is accelerating fully determines their shift speed.

The sad thing is some drivers stick to that one way when operating the clutch and foot pedals. This often causes an unpleasant ride.

The trick is:

1. Do everything at the same time - clutch shift throttle
2. It's mostly in the legs and foot pedals
3. To use equal amounts of throttle and clutch
   1. Simply put, how fast the throttle is depressed is how fast the clutch is released.
   2. Although equal force is crucial, both the clutch and throttle pedal travel / force / bite point defers. One needs to determine where the pedal sweet spot is to achieve equal timing and force
4. To determine where the clutch bite point is.
   1. Some people depress the clutch pedal entirely when shifting without taking into account the free space between zero and bite point. This gap will effect smoothness significantly.
   2. determine clutch bite point by releasing the clutch when in gear. Once determined, one should shift within the optimized clutch pedal travel.

I made a video from when I doing a warm up before my race qualifying. I hope it'll help anyone who wishes to improve their footwork

(please ignore the left foot braking scenes. It is generally not needed. This is a special case. The pads were new and I found the brakes in this altezza require some tapping to tighten the brakes before hard braking)

Too costly, have to half cut the rear also....:rolleyes:

Nice footwork and video but I noticed your left is always resting on the clutch pedal and never on the foot rest ya. Is there a specific reason?

Btw this is also another amazing footwork from the great Senna, heel & toeing and blipping the throttle using loafers in the NSX, at 1 point heel & toeing as if balancing the brake & the gas in the fast 130R.

No real reasons to be honest, also depends on the car driven. It's also a choice perhaps. Come to think of it I hardly use the foot rest

Senna's video never ceases to amaze everytime I watch it

If driving on highway or places that do not require gear change then can use foot rest, but in racing almost changing gear every now and then how to use foot rest.....lol

yeah although that is true, many drivers do use the foot rest actually. But like you said, I hardly find a reason to, maybe during the 2 straights at sepang that's it. Other drivers return their left foot to the rest everytime they are off the clutch, i consider it a preference

Not really true, you look at that Senna's video, he always returned his left to the foot rest. If you like to watch Australian V8 Supercars, then they have many videos of their footwork and you can also see they still use the foot rest when not engaging the clutch. Even many rally drivers also still use the foot rest. I suppose like Tom said, just preference only then. I just worried if resting on the clutch all the time then will wear out the clutch faster but I suppose if already used to it hence the feel of the left foot is already very matched with the clutch pedal free play then should be no issue.

Impressive driving and shifting skills you have Tom. Do you drive a manual car daily? From what I know, you owned a Mini and a V12 BMW.
