I'm on street tires, BTW.

Scott Adaire showed me a line through 8 that really works for me. Very slow in, but quite fast out when I do it right. Instead of staying all the way out on 8 before turning in I stay a lane or so over to the left. That puts me deeper into 8 when I rotate the car around, which gets me straighter through 8 (very late apex) and faster into 9. Almost a psuedo-double-apex line.

I've never timed it so I'm not sure about the overall net time, but since 8 just leads to 9 it's got to be a throwaway compared to speed at the start of the main straight.

 

I wonder how fast mikegarrison is compared to Tedster and Jerry at PIR.

 

8 is definately NOT a throwaway! Your speed down the front straight is linked all the way back to turn-in to 8. The question is how far to track out of 8. Track out too far and you can't do 9 flat out. Don't track out far enough and you've given up speed all the way to turn 2.

The goal is to carry as much speed as possible out of 8 going full throttle all the way through track out of 9, AND be at the edge of adhesion the whole time, AND scrape the 9 apex wall AND drop an inch of tire off pavement at the exit of 9, AND find somewhere to do a 3->4 shift. The best line through 8-9 is radically different from horsepower cars to handling cars.

It's the most difficult section of track to get right with the greatest consequence to lap times of any track section I've seen. And if you screw-up 9 badly enough, your car leaves the track on a flat-bed.

I love it!

I'm with Ted, I'd hit rev limiter in 3rd close to trackout of 9, but that is about the last place I'd want to actually hit rev limiter. So I usuall relax the steering input and shift(smoothly) just past apex.

 

wow.. i didnt' expect 24 people replied but seems like the subject has changed towards the end. hahaha
but anyways, the purpose of changing the final drive is because I want much faster acceleration in 1 2 3 gears. i mean.. through out the year, the chance of going to track (for me) will be only 20% most of the time will be on road. i guess acceleration faster will always do me better on street.

plus.. investing on the final drive is always better than putting much money on cams ...etc.
at least u feel much more differences.

before I had a civic si. i got spoon cams, gears, valve springs retainer... intake exhaust header, but i dont' feel much of a big differences on straight acceleration. anyways, comment pls

 

Ha Ha, you got highjacked! No worries, it's a regular occurance in these parts.

Since you are using your car more for stoplight to stoplight applications, I think you'll find this is the best way to increase acceleration without increased wear on the engine.

But, also consider your ability to take turns at speed. After going through some of the backroads with you on the NSX drive at 40-60 mph I can see how you like your corners.

So think about that drive and how the car felt. Then compare how the car might feel with a new set of gears. You might find yourself in a higher gear and out of VTEC. Then again, even if you are a tad bit slower on a corner you could make up some time on a straightaway.

 

(I assume you mean PR, not PIR.) Slower, no doubt! But I do get to the rev limiter in third at or even just before the apex of 9, so perhaps on that one corner my line (when I hit it right) is better. Timing would actually tell the story, but I've never timed myself.

So now I short-shift into fourth. Otherwise I just give up too much time on the throttle, because I'm already feathering it before the apex if I stay in third. Can't shift and especially don't want to bounce off the limiter right at the apex, or it's into the wall.

 

true. I guess it has up and down side w'/ final drive upgrade

Optikal, i kinda wanna go to that back road one more time. should we ?

 

Mike,

what speed do you get to before braking for 2?


Sorry for the hijak!
