When do you shift? [Merged 7-8] points shifting revs point

[BlackbirdOfPrey]

I usually rev to 5500 and do a quick slip. When I feel it grab I drop it. I don't bog it off the line, and it launches strong, so I dunno what the problem is. I can beat all the cars I go against off the line, but can't get below 2.0 on my 60ft. Even then, I still need to know where to shift to 2 at. Any advice on the 60ft would be nice as well. I read a few threads on it, and I don't see much difference between when I do and what everyone else does to get sub 2.0 60ft's.

I've hit as low as 1.8x 60 ft. on stock clutch AWDs. Quick slip as a high rpm (around 4500-5500) and shifting as early as 6k. A better clutch like a ACT 2100 can get you as low as 1.64 (at least in my case) on street tires and mid 12-sec car. That is done with a 6500-7k clutch dump. 2600 on the other hand is a different story. It all comes down to practice. But be careful on the stock clutch......she doesn't like to be slipped a lot.

Make sure your car is not rolling at the line and prematurely triggering the beam. You may be surprised at how that affects your 60 foot. I have seen that happen to my car where identical launches yielded a 2.1 and a 1.7.

Personally, I don't even look at the tachometer when I'm making my 1-2 shift and it's the only shift I make by "ear." From looking at my logs and AFC peak points, it comes anywhere from 7,600-7,800rpm with a 5,500rpm launch rpm.

I'm still learning how to launch her hard without breaking parts. I do cut alot of 1.7x 60's and my current best is a 1.72. I will be increasing the launch RPM to 6K this year and let her rip.

depends on clutch

I shift my 1-2 by "ear" also. Most the time it's between 6500- 7000k while launching at 5000k. The trick I found is to shift hard and fast right as the front nose trips the 60' foot beam. There's no need to try and carry the car all the way past the 60' foot block then shift. That will in turn ruin your 330' time but that's a different subject.
I cut consistant 1.6 60's with a best of 1.610 with kumho's at 30 psi as of right now.

Boy, thats a wealth of info on 1-2 shifting in a awd car. Hell will you be my driver next season?

! :laugh: Maybe he will cut some 1.5xs for you.

Hey guys.. Gotta question for ya. Ive got a 90 fwd turbo laser with a non working tach. REplaced the tacho interface and gauge cluster - no go. So, I thought id ask you FWD owners where I should shift at for best performance when at the track. I ahve been going every 30mph, beacuse in my 91 awd, that was redline every gear. But, I heard that the FWD tranny's are geared differently. So, If someone could please inform me of the mph per gear from a fwd please!!

i dont even look at the tach,....

listen to the engine,... when it feels like its under stress shift...it should be pretty quiet at coasting....

 

[BaddAssGst]

Not exact numbers here but I try to get out of first around 25mph, run 2nd til about 60, and then I think 3rd runs out somewhere around 98-99mph. If for some reason your trapping 120+, let me know and I'll go check to see where 4th ends at.

Your not trapping 120mph.. didn't think so.

on my 2g 4th runs out at about 140 mph....5th is good for about 172

How is 140 in 4th and 172 in 5th possible? I would think you would be rpm limited to around 150-155. I don't see you hitting either. I could understand if you have a longer fifth gear but the 2g I drove couldn't get past 137 in 5th gear and that was at 6600.

 

[sjgYFZ200]

What he means is that its "geared" for 175. Could your motor do that? No, but your gears could.

 

[tstkl]

o at the track, thats a bit harder, disregaurd what i said...

 

[BaddAssGst]

What he means is that its "geared" for 175. Could your motor do that? No, but your gears could.

But at what point can you hit 140 in 4th gear? Is that without a rev limitter hitting 9 grand on the tach? I'm not starting any wars here, just stating that the stock 4th gear isn't geared to 140, anyway you look at it. I've ran 4th out many times and never have I come close to hitting 140.

 

[Talesin]

Third runs out at 105, 7Krpm, on my buddy's '90 GS-T. Shocked the heck out of me, and made me grumble at my GSX, 'til I realized that the 1/4s are about the only place you'll ever need to go above third, legally, unless you sneak into a track day at an oval. :b

 

[turbo98eclipse]

just wondering if anyone could help me with finding the peak points in each gear so i'd kno when to shift and not lose power/speed. i have a gs-t spyder with intake and thermal exhaust 3" downpipe and cat (jus started modding). also, what's a good launch rpm?? thanx for any help

 

[karbon]

We can't tell you your shift points. Those are to be determined by a dyno chart as every modification you make changes your horsepower and torque profile, and ever every car is different. Go get one a dyno, and if you need help interpreting them for shift points, post them here and you'll get some help.

 

[Spln_Hrd]

i would go by feel. if you have a friend with a larger than stock turbo you can tell the higher the rpm the harder it pulls. if that is how your car feels which might be possible because of adding your exhaust then run it to redline. normally if you increase flow you should have your powerband at a higher rpm.

i would shift at seven if it still feels good.

 

[shwinp]

Note that staying in a particular gear (3rd gear) even if you're hitting the rev limiter can give you significantly better times.

Maybe I'm wrong, but could you tell me how letting the car cut fuel because your RPMs are too high is preferrable to upshifting and getting all the torque of the lower side of the powerband? I vote for continuous acceleration over sporadic acceleration any time.
My buddy is trapping 13.7 on a stock 2g Talon and he doesn't do this.

This may not work for all - I'm close enough to the quarter mile in 3rd that shifting to 4th would significantly hurt my time - probably due to my slow ass shifting Note that I've tried both. Maybe your friend can obtain low 13's by staying in third. I know quite a few others where this worked for them. Just sharing an personal observation.

ooo...good point!! as you can tell, im a noob to 5-speed cars. i pretty much have everything down like starting on hills etc.. but the only thing is my shift points are a little shakey/jerky and recently ive been having trouble finding 3rd 1st time its ever happened...i dont want to start a race out and then go from 2nd back to 1st and possibly blow my engine, so i just have to practice that a little more. also, what rpm do you guys launch at? thanx!

 

[Burnett03]

No.. from my experience to run 13's on these cars you must get into 4th gear.. Maybe if YOU shifted to 4th you could improve from those 14's.

 

[trbotaln]

My car is faster when I hit 4th in the quarter. I have tried holding out 3rd gear and the car really craps out and is slower. I hate having a t25

 

[Vexiis]

This probably has been asked before; with that said I searched quite a bit but only found things about automatics shifting strangely or people have grinding/ shifting problems.

I know the manual says to shift at:
2: 15
3: 25
4: 35
5: 45

but I know that is very conservative, when I am driving carefully and babying the car I do those.

My question is when should you shift, and what do (personal opinion/experience) shift?
casual driving and pushing the car hard.

(If there is a thread about it I missed, can you link it quick and let me know what you searched for so I can get better at finding them).

Thanks
