Default Gearing and Shifting Dilemma at the Track - What Would You Do?

I thought I would get your input and thoughts on my dillema with corner #8 at Second Creek Raceway. I know that you can only speculate, but I'd still like to hear your opinions and maybe we can abstract the discussion.

Turn #7 is a slow second gear corner. I am hitting the revlimiter in 2nd gear somewhere inside the red box. Turn #8 really ought to be taken in 2nd gear as well as it is pretty tight and it is slightly uphill. If I do not shift into 3rd, then I have to lift and ease up to the corner entry but if I shift then I am way off cam coming out of the corner. I'm damned if I do and damned if I don't.

What would you do? Where do you take the penalty in speed? I have been mostly leaving it in 2nd and concentrating on corner exit speed for the run up the slight hill to turn #10.

Shift then downshift. Without being in the car its hard to say. Hell it would be a little easier if I was on the track before.

What FD do you have?

Get an ATS FD and then take turn 8 in 3rd

Sorry, should have mentioned that there is no time to really shift and then downshift again. Turn #8 is really just a quick stab on the brakes and then turn in (it has some nice camber to it).

Stock FD.

Leave it in 3rd, turn in earlier, use the curbing, keep your vision up and carry the momentum

I would also say to stay in 3rd. Seems you would lose more poppin the revlimiter, than just taking the turn in third. You wont lose to many rpms going to 3rd.

What he said. Unless you absolutely have to slow down to ~40mph for T8, leaving it in 3rd seems like the better option.

Get a data logger and try both ways

Or a more cost effective solution would be to do what RJ said; just leave it in 3rd.

There's a lot to be said for leaving it in second and feathering the throttle at redline for a little while, then being able to use the torque of second as you approach the apex of 8. I would try it both ways, a whole bunch of laps each way, and see which way you like better. If you still can't decide, then it probably doesn't make a whole lot of difference either way.

40 mph? Second is good to 60, and it's worth downshifting even if you're only slowing to 45-50.

Funny you should say that, because Second Creek isn't all that great a track in most ways. But it's cheap to rent and it's convenient to Denver.

The problem with building a track in AK is that you won't get many people driving there from other states.

also great to have a higher reving motor in situations like this.......ex. Best Motoring did a comparison with a spoon CTR(11k rev limit) against a stock CTR(8.5k rev limit) on a track...seen that vid??

True but his problem is he's not sure if he wants to go to 3rd for a short period of time (I'm guessing about a second?) before having to brake and downshift again to 2nd. Leaving it in 3rd @ around ~50 isn't going to be horrible. It out of the "powerband/VTEC" but he could just floor it and get around the turn with slight bog.

But that's just my take on what he was trying to explain.

This is what I'd suggest First.

This is what I'd suggest second.

Third I'd suggest seeing if changing FD's to the ATS 4.93 is a viable option and definitely driving in 3rd.

Fourth I'd suggest just not braking altogether and doing 4 wheels off lawn mowing, but what do I know

Driving the higher gear even though you're off the big lobe can be many times more settled and depending on elevation could even be quicker if you carry enough momentum/speed through the turns.

I'd suggest adding a turbo kit. That way you can stick it in 3rd and haul *** out of the corner.

Worst advice ever

Nasty clouds of burning oil were pouring out every crack on my hood, and I have a lot of crack. I babied it home and found that the Endyne can had filled with oil, and had then evenly distributed it all over my engine (again). </TD></TR></TABLE>

Track is STILL hot, car start smoking profusely. Driver's side. Paint on hood is bubbling, I decide to hop out and try to fix it. I crack the hood and spray the bottle along the driver side (a bit of flame shoots out, yikes!) More smoking, less fire, so I pop the hood. There's smoke everywhere so I spray everything. </TD></TR></TABLE>

leave it in 2nd and let the rev limiter do it's work.

you said T8 should be taken in 2nd gear.... there is no need to go to 3rd just to then go back to second.

just don't upset the car with the engine braking that you will have at those revs.

Last track day I attended my instructor said, "There's probably only one other guy here who wouldn't be scared shitless this car."
