So....as some of you may know I'm fighting linkage isuues....BUT.....of the passes I HAVE made through all gears...I'm between the times below:

13.43 - 13.85 consistantly. I've pulled almost identical times wether I go through the traps in 3rd.......or go through in 4th.

The question is: For a modded LNF...(7K redline)is it better/more advantageous to keep it in 3rd and have power dying off a little at the end...........or take another shift and have power climbing still as I finish? (either way I'm getting same ET's and MPH too)

Gut feeling says hit 4th.....but I see ZERO difference in times or speed. Couple days ago at the end of the night I was staying in 3rd just to avoid having to fight into 4th with my linkage not exactly right.

Any thoughts?

 

I know I had the high rise wing, and was only trapping 107-108 took it off and trap 112-113. So if your going to be at the track alot I would take it off. As for the shifting I used to **** at 6k so I would go into 4th, someone told me to stay in 3rd, dropped 3tenths my first pass and picked up one mph.

 

in that case.....wingless FTW! LOL

You're runnin 12.7's!?!?!?!?!?!?!?!?!?!?!!?!!?!?!!?!?!!?!?

 

I was running 13.0's. Then I was told to leave it in third and it worked.

 

I couldnt stay in 3rd before my tune......now I can. I just thought with shifting a lil earlier in each gear and hitting 4th to where I'd cross the line at peak power........I'd be better off than squeeking out in 3rd. Only take 4 passes in 3rd........will test it some more next time!

 

Stay in third.

 

cmiller..sent you a PM

 

So, it worked for you huh? I think I told you that didn't i? I told someone that this week... IDK who though, lol.

SUXKOST: When I changed my rev limit to 7k, I changed it in 3rd gear only. In all the other gear, there is no need to run it much past 6500. I have 1,2,4,5 gear limited at 6600, and usually shift about 6500. This seems to work for me. Then, I shift into 3rd, and forget about it until I trap. You will not see much in your trap speed from this though. But you will see it in your time.

 

Yes it definitaly worked.

sent you one back.

 

Yes run out 3rd gear if you have the power and speed you should be close to the end by the top of 3rd... if not you'll shift just before!


Move the rev-limit to 7200 (just for drag runs) that allows you to stay in the power band in between shifts.

Just my .02 take it or leave it

 

Oh, Sukxost...

I forgot to mention... if you shift too early in 1-2, then the car is put in the low end of the powerband. Shifting about 6500, will drop it back in at a meatier portion of the powerband in the next gear. IMO, my car doesn't lose much power until about 6700, and that shows on my HPT logs.

 

I know if I can get through in 3rd its the best.....but with the turbos power earlier I thought 4th might be better.

Got it....will respond soon.

Having been going through 4th mostly this far I've been shifting right when I hit 6K. (So when I DO go through the traps the boost is right about peaked in 4th)

Just what I was saying above. I think I'm going to experiment more in 3rd through the traps. Instead of shiting sooner(as I was trying all 4 gears) I think I'll drive it exactly like I did my stage2 SC. Just use MOST of the RPM's before redline. Maybe 6500 as a couple have said above.

This is my first turbo car and I've learned very quickly but knowing that the powerband is SO different I thought the top of 3rd would just be too weak. I RARELY see turbo cars at the track staying in 3rd. It's half common to see STI's and **** going into 5th! Saw that **** a lot in WA!

 

Ok... I think you get my point... I mean, it is all trial and error. I came here and read what was working for everyone before I tried doing what I was doing, mush the same as you are. I am sure if you try it out, then you will get her. I am about to the point where I am closing in on 4th gear, even at 7k rpms... once that happens, I am going to need to go with a bigger tire, or start shifting 3rd sooner. My highest trap ever was 112, and that was shifting into 4th... staying in 3rd, I can rarely jump past 109, even though my times are going down.

Also, what are you launching at? Are you spinning 1st, or do you let off? Just curious...

I've had a 13.43 @ 107.99 going into 4th with linkage issues so I was not NLS into 2nd.....so if I can get my shifting points figured out using 3 gears.....12's are reachable.

I hate beating a dead horse, but with this linkage **** going on(think I got it set very close now) I've not really hammered 1st gear as 2nd gear linkage is my HUGE issue right now. I'm shifting into 2nd without NLS at 5500 is to avoid higher RPMs in case I do grind 2nd.
SO>>>>>most my 60's are 2.30-2.35. I bog BIG going into 2nd usually because of no NLS and shifting early.....but a couple of times I've shifted as I normally would on the track and actually made it into 2nd clean with a lil spin and got a few low 2.2's.....but still shifting at 5500-6. I can't wait to get back out and have my linkage right....and max out all 3 gears! Get that parachute wing off and who knows how low I can go.

CMaster stage 3+ or 4; solid upper mounts; tranny bushings; and DR's on 16 or 17's.....some practice.........low 12's!

OH...here's my last dyno. See the WHP drops off just past 6000. The WTQ drops off at 5600. That's why I'm shifting past there.


I think with another 800-1000 RPM's the power is too low....but I'm gonna try it! Shifting 'round 6800ish

 

My opinion, hit 4th, the original redline was at 6250 for a reason and it's not because the engine can't handle a 7k redline. If you NLS you'll negate the time required to shift and re-spool and avoid the higher redline where the engine's clearling losing power at a substantial rate based on your dyno runs. Shifting around 6400 should bring you out at the 4000ish range leaving you with just enough powerband to push across the line.

Just an FYI, venom09 mentioned even on his stock TC he was getting better times when shifting to 4th instead of revving it out in 3rd at the end of the strip . If he sees this hopefully he can confirm but he mentioned this right away when I asked if he was hitting 4th at the end or staying in 3rd.

 

Thanks for the info. Several guys saying staying in 3rd is getting them better results so I'm going to at least take 8-10 passes and see what my numbers say. Stock redlines are not always set for the premier shifting point for performance(not that you were saying that).....but a general guideline and to show you where the rev limiter will hit. We all know that.
I think instead of mildly shortshifting so I can go into 4th and use that power in that gear with some track room left (to avoid going into 4th right before the blocks) I'm gonna max out all three gears as I said above to see results.
Can't hurt....it's all trial and error. Might work better for me.

Maybe I just need a better/different tune to maintain more topend power and easily keep me just using 3 gears. LESS SHIFTS = LESS TIME SHIFTING

I tried to have my tune adjusted to:
Significantly limit boost in 1st for garnering best 60' times
Gradually increase boost in 2nd to avoid having to feather pedals
MAX boost in 3-5

Did not happen that way but I'm doing the best I can for now. Once I get my clutch; mounts and bushings......re-tune! I don't have the knowledge or assets to tune it myself and be able to make those tiny adjustments that make all the difference when it comes to the strip.

My dam WTQ practically doubles in 1K RPMs

 

Good luck, let us know how it works out

 

I have fam in town next Fri night.....they leave Sat morning....I gotta find out if the track is open for T & T Sat night. If so I'll have some results next Sun morning If not It'll be another week after that

In the meantime, I've got a couple buddies I'm gonna get some vids of doing some freeway pulls against:
A modded and tuned STI-novice driver
A modded and tuned 350Z-seasoned driver

 

I have solid proof. Not saying Venom is wrong, but until he comes in here to back it up... I'm gonna stick with my opinion. Now... in a completely stock car... yes, you have to shift to 4th, otherwise you are bouncing off the limiter in 3rd, and well, obviously there is no power there. Its truly a different story in a tuned car.

I have my tune set up for the most power under the curve. It really hits hard at the low end of the midrange. Never been to the dyno, so IDK how the curve looks, but the way it feels is good. I have 100% torque in all gears, all ranges, but I will be playing with it the next time i make it out to the track so that I can maybe get a bit better 60'. Also... I NEVER NLS 1-2 for a couple reasons... A) Its very rough on the trans and B) it only brings out a bunch of wheel spin.

 

I am having some major issues.. Get'n kinda upset, but here i go. I've been working at the closest track.. about 2 hrs away. After i let my car cool. My first pass is usually my best. I too am having issues LNS into all gears. So, i usually dont LNS into 2nd. I have constistant 2.2 almost 2.1 60' and with a good pass i can NOT get any faster than a 14.3 pass. I am completely lost. The track is in Tulsa. Not always the best prepped for street tires. C6 and C5 Vetts are around my times.. something wrong with that i think.

So im asking for advise and maybe an answer to my delima. thx.

 

Take the fat bitch out of the passenger seat! LOL JK My best 60's are high 2.1's and 2.0's as well. I really struggle getting the power down without spinning going from the line AND getting into 2nd.

 

Yeah.. I like the full figured ones. hehe..

Other than the shifter issue..I've had it replaced already.. so might need some type of adjusting.
I don't get the 1/8 mile time. Usually like a 9.7 or lil lower. It does not make sense to me .. its like i'm losing power the longer i go down the track. I've trapped 101+ before.. so i dont think its that then. Kinda feels like i'm spinning the whole way down the track. I dont have that feeling of "being pushed back into the seat" like i do on the street. Been looking for a DR that will fit the stock wheel and keep my Brembo's. Anyone use any?

 

So im seeing other people are having trouble with NLS 1-2 shift, is there a fix for this?

 

No. NLS just doesn't work from 1-2. Well, it works, but there is no traction after you do it so its pointless.

 

Ah okay, ive been having trouble just making the shift for some reason. And only at my last at the track.
