High rev Q's

[kinkyllama]

To gain max performance(acceleration) gears should be always changed in range between max.torque and max.hp
You should get dyno data of your car and mark points of max.torque and max.hp - ex. 4400rpm@max.tq and 5800rpm@max.hp for x20sed. That's why it is very useful to have "shift light"....

Yeah, well to a point. I think its better for my car to wait till a bit after the power starts to drop off, but not much. My exhausst is way to big for my car so I dont make much power down low.. so I try to keep the rpms up a little higher from where my power drops off cuz if I shift right where my power starts to drop I get too low in the rpms.

So you have to change gear ratios to fix this problem........

Nah, I'm putting on a turbo

it's time you get a new FGR boy... you'll slap a piston before long doing that on stock internals...



that or learn to left foot brake

eh, I dont like left foot braking at all

[Audacity Racing]

the other thing is why are you downshifting at that RPM? there is no power to be had from 6000+ so there is really no point in DSing there.



yeah, after reading the post thouroughly... YOU NEED TO LEFT FOOT BRAKE, end of story. it's a faster style of driving anyway since there is no coasting, it's either throttle, or brake

Not at all

in Japan the drivers do this:

Left foot only for clutch

when they downshift they use the front part of the feet for braking as usual

and the heel for the gas pedal so they keep the rev's up

Dowload Videos From Best Motoring they are from Japan and they show their foots and rev's when driving

is the heel and toe technic very usefull

i dont do it my car has a A/T hehe

you'll also notice that they over-rev and in teh classic super car battle they overheated the NSX. point is that if your gearing isn't where you need it to be, left foot braking is faster. when you have to match revs above 5k, your gears aren't appropriate and you need to slow down to get back into the powerband. you will have more effective power curves pulling through the corner if you can drop back down into a torque region, even if you have to slow down considerably more.

if you watch formula 1 races a lot you can see this concept pretty clearly when cars will appear to be going slower in the corner, then pass the guy who took the inside line because they are in a better rev area for the power of the engine.


there is far more to driving the car than just matching revs and trying to get the highest speed while entering a corner. maybe with some r-compound tires you'd have more grip and wouldn't have to drop a gear at all.

What do you mean there is no point in DSing there? I'm DSing to prepare for the next corner.


I dont coast, I'm always either on the throttle or brake.. while I'm on the brake I DS to prepare for the corner

[Audacity Racing]

so stop letting out the clutch above 5k... problem solved

[Nubira2.2]

but what about the shifting?

in F1 they use Flappy Gear Box

some time in BM they use Sequential Gear Box

when they use a normal tranny is when I see the heel and toe

[Audacity Racing]

it's still a question of getting into teh right rev band. above 6000, there is absolutely no power in our engines and certainly not safe above 7000 as he is doing. in order to get to the rev band he needs to be in he has one of three options...


1. New FGR
2. Left Foot Brake
3. Keep the clutch in going into the corner


there is really no reason at all to go over 6k when downshifting...

[Nubira2.2]

in my opinion it is useless to get in my case my engine above 6000 rpm


did you guys remember the dyno graph of the UD pulley ?


92hp @ 6000rpm thats sad


Max TQ and HP are arround 4500 to 5400 rpms


our cars doesnt have a good head cam that would produce power @ high rpms

I used to shift at 6000-6200 for some reason I remember that looking best when looking at the dyno. But I just looked at the dyno of Chris car (only diff in our cars in performance is I have spark wires, lite flywheel, cai instead of sri) and It looks like I should be shifting at 5600-5700rpm. Audacity, take a look: http://www.360dynamics.ca/UD.htm

This is shifting at 5700:

1 -> 2 -2238 (to 3462)
2 -> 3 -1803 (to 3897)
3 -> 4 -1357 (to 4343)
4 -> 5 -1221 (to 4479)

From 1st I should shift into 2nd at 6150. In 2nd I should shift into 3rd at 5650. In 3rd I should shift into 4th at 5150rpm
1 -> 2 -2415 (to 3735) <===thats shifting at 6150
2 -> 3 -1787 (to 3863 <===shifting at 5650
3 -> 4 -1226 (to 3924) <===thats shifting at 5150

Hows that look for shifting? Shift lights dont allow you to set different shift points for different gears do they? Or can you program the msd dis-2 to set different rev limiters for different gears?


I dont see how left foot braking is really any faster than heal and toe. I've seen you can do some extra things for RWD cars.. I remember one road course they recommend for RWD cars through one corner to slightly touch the brakes and gas to make the car squat down a bit.

It is not possible to ride with stock car like WRC. You should change at least camshaft and after that change gear ratios according to new dyno data and keep try with left foot.....

That's just because they can accelerate earlier in the corner. A good driving line is key when racing.
