what rpm to shift at

[polski--ms3ski]

well im not sure if this the right place to post this but im curious wat you all shift at i now that the boost starts to cut off at 5500 but i still shift at about 6100 so im asking wat would be the optimal shift rpm because i have this friend with an srt4 and he beat my friend 5 out f 7 times in an ms3 with an intake and open dump while the srt had an intake and he is conviced that he will demalish me anyone chime in ?? thanks (attn)

ur mods? stock 5500 is the spot. if you have the right mods you can boost and pull past that, but otherwise not ne further.

not to down or anything, but can ur friend drive? was it a walk away victory for the SRT?

 

[polski--ms3ski]

yes all stock for me well my friend is one of those guys that bought the car because it looks nice and such cant really do any modding himself me and another friend put on his intake so yea the srt walked him four cars from a roll and about a car or two from a dig wat would you recomend launching at allso he launched at about 2 i think and the srt at 1800 amd the two times he did win it was cause he jumped embarresend him self more then neccisarry

shifting at 6100 is too late i think. the car is losing too much steam. if you are shifting at 6100(from what you can see) you are most likely shifting at 6200 in all actualality.

my car pulls to about 6200k as well but its still losing steam pretty quickly after 5800. i started shifting at 6100 as well once i put my mods on b/c the car was pulling which it didnt when it was stock. but when i raced my boy it wasnt pulling as hard as i thought.

so i shift around 5700k which puts me around 5800 and it seems like a sweet shift point. when i would shift at 6100k it looked like my boy would creep on me just a tad between 5800k and 6100k(shift point) for each shift.

but when i shifted at 5800k he didnt creep on me anymore.

by the way, he has a 350z with injen exhaust, gutted cats, upper and lower spacers and intake. from a second gear roll, i jump ahead by about a car length and hold that distance until about 140

1st - 2nd = 6K
2nd - 3rd = 5800
3rd - 4rth = 5500

Thats what i shift at.

Yeah I have almost the same mods as you and in 3rd after 5500 RPM the car just seems to turn into a VTAK (hand)

5.5k is bulshit for me I recently raced sti that guy in my work have...he is pushing 300whp so 2 first rolls he got me by 1,5 cars and i was shifting at 5,500rpm ..... 3rd and 4th run i smoked him by one car however this time on 4th gear i was pushing till redline 7k(yes 7k i have rev limiter removed because im tuned) and you could see diff maybe power was droping because of our turbo but I gained more top end which allowed me to beat him everytime when I wasnt shiting at 5.5k ....

Maybe its just me but driving wot and trying to shift at exactly 5500 is a lil difficult. I mean if i were racing/driving aggresive (which is rare) I think Im lookin more at the road than my tach hope yall are too lol. I just try to aim for around 6k maybe my best advice (nobody)

Unless you have an upgraded turbo and up'd boost I have a hard time believing you could beat a 300+ awhp sti unless he missed a shift or messed up somehow. If your car performs better shifting at 7K then it must be the tune. Shifting at redline 1st - 3rd gives me a 6.5 second 0-60. Then when I shift at the sweet spot I can break 5.5 sec pretty easily. Thats using my aeroforce scan gauge though . . . who knows how accurate that is.

Truth be told, an equally modded SRT4 Neon is faster than our cars in straight lines. You want to beat a Neon SRT4 get on a road with turns, you will never see him again.
If you cant shift at the right RPM's get a shift light or set up your dash hawk to flash at say 5k so by the time you shift you are at 5500.

ive learned to time how long to stay in gear when i run, and after a while could hear the spot in the power band to know when to shift. if its not exactly 5500 o well but i mean in that area, your dropping off power after that (if your stock)

ive got a couple minor bolt-ons, and you start to tell when the car becomes efficient enough to shift at a higher RPM, but i dont see the point, you still dont create enough power to keep going.

I'm very skeptical of getting the jump on a 4wd sti with 300 whp. by tacking up to 7k rpm. You can mod the crap out of our cars and unless you can find a way to get around the ECU nanny that cuts our power at about 220 hp in first and second gear, you really can't get better than about 5.5 seconds to 60 mph, and even a stock sti is going to better that. Stock Sti's hit 60 in the 4.8-4.9 range and the quarter in 13.3-13.4.

And I agree with the later post that unless you have a bigger turbo, thermal insufficiency takes over soon after 5500 rpm. No amount of tuning is going to let a small turbo housing push more air without oveheating that air and losing more power than it's making.

What tune on a stock KO4 turbo would overcome that?

Now, if holding to redline in 4th only in order to avoid the lost time of an early shift to 5th is the only time where 5500 rpm was exceeded, that might make a little sense, perhaps if that is at the top end of the strip close to the timing lights. But on the street? Maybe I'm confused?

you prolly didnt ready what he said. he is tuned. he has the Piasini Tune.

which i cant wait to get


yall may want to do alittle reading up on the Piasini flash

i should have around 270whp thx to piasani flash...

Probably of no consequence but, the MS3 has the identical power to weight ratio of the 335i, it does have a little more torque per lb than the 335i however. Magazines seem to claim the 335i does around 13.4 in the 1/4. Just my opinion, but If the MS3 had the traction of the 335i, it would do the same in the 1/4.

I think a 270 whp MS3 is capable of running with a 300 whp STI, it does weigh 250 lb's more than the MS3.

youre right....this flash is amazing not like ap ....and it was from a roll btw...on stock I would shift at 6k car

Ive read all of the like 3 threads about the piasani tune on this forums. Ive asked about it and everyone who was talking about it vanished for like a year. I was ready to buy one but im a little suspicious. Seems like a great deal but like only 3 people on these forums are running the tune. Also tried googling it an nothing. Seems like a "sketchy" product.

 

[AMS38U]

drive your car and see when you feel it fall on its face then shift EASY BREEZY. ill go ahead and include the formula for ya

FALL ON FACE = SHIFT

lol

youre not local but local gus drove nypes car on the meet and they were amazed how car feels....he is puting 285whp and 315tq with sri and tmic only so numbers are saying something....but this thread is not about that....

 

[Circle9]

That is impressive, how much for the tune?
