if you're staying NA go 4.77

 

actually Ryan... i just remembered you got an ap2.... get the 4.56/4.57 gears instead.....

your top speed will be roughly... 138mph with the 4.56/4.57
with the 4.77 you'll be down to around 131mph

 

don't forget the new 5.1 gears that the J's car is using..

 

ap1 with 4.77 gears + aem cai = 13.2 quarter mile time

so i would assume an ap1 with 4.56/4.57 gears would run around a 13.5-13.6 easily....

while a stock S runs around 13.8-14.1

 

Are those Dolby Digital or are they DTS?

with the lower redline, I would go 4.57.....4.77 may be a bit much.

 

5.1 wouldn't even be for a daily driven car.....

 

I am struggling with he same question.

I am back to NA now and am keeping the car for now, and wondering where I need it on the track and whether 4:56 gears are enough

I always had trouble in turn one loosing VTEC (SC'ed and NA) taking the corner in 3rd, 2nd made the car much looser and didn't seem help lap times. I need to enter in 3rd faster but I am not sure I can maintain VTEC with the 4:56 gears when entering corner about 60 MPH or so. NA it would take forever to get on the cam (past turn 2)

One thing I really liked with the Supercharger is I could shift less which is much smoother and easier on the car. Now with the 4:77s how many times are you shifting per lap?

Here is what I did with the 4:10s and the SC.

Turn 1-2 6th to 3rd, turn 2-3 3rd to 4th, sometimes carry 4th in 3, turn 4-5 4th to 3rd, Turn 6 3rd to 4th, carry 4th (out of Vtec for a bit but full throttle) past turn 9th, 4th to 5th before 10, downshift to 4th before 10, 4-6th on straight

Thats roughly about 8 shifts per lap, I need to go back and study older tapes and see what I did before.

Will the 4:77s keep me in the power band or I will have to shift a lot more?

Anyway I have plenty of time to think about it.

 

I went between 3 and 4th at beaver... 4.77 guys were up to 6th on the back streach. Its deff. gona be alot more work.

george, what was your top speed at summit main?

 

NA ~ 120-123 (124-125 rarely) I know I can carry more speed though 10 now.

Supercharged 128-135 shifting at 8500 RPM. I prolly could have gone faster, but would always screw up turn one by overbraking when I went deep.

At Beaver, I could shift into 5th on both straights, but really didn't need to.
