I added 21 hp with my WarpSpeed Y & B pipes and a cone air filter. Now my automatic transmission shift points have gone from approximately 6300 to 6500. Not sure where the revlimiter cuts in but if I add much more power I'm going to hit the limiter before shift. Anybody else experienced this?

Apparently the automatic transmission shift points are speed limited. This would explain why it is shifting higher. More power to the converter means more slippage and higher rpm at a given speed.

 

I know some Automagic 4th gen guys hit the revlimiter after installing the MEVI.

 

Yeah I noticed the same thing after I installed the Injen CAI. hey Larry didn't you have that before? The Injen CAI? Did you take it out? And why?

Also the shift points changed again after installing the Cattman Y-pipe. Bummer is I also noticed the transmission slipping. Damn now I have to take it all off again and put the stock back on before taking the car into the dealer...what a pain in the a**

 

Pretty soon you won't have to manually shift? Kakakaka!

 

foodmanry,

I never had an Injen intake. I added a cone filter on a Berk adaptor before my exhaust but for only a short period of time and really didn't pay attention to my shift points. I took it off at the time because I really didn't like the sound. After seeing the hp it makes I decided the sound wasn't so bad after all. LOL!

lcf,

With shift points at 6300 no need to manually shift.

mzmtz,

Excuse my ignorance but what is a MEVI?

 

After I put on my test pipe my shift point also went up a ways.

 

Same thing here. After installing the Injen CAI, I noticed my shift points are higher.

 

another larry here, not sure which one foodmanry is referring to. My shift points have not changed at all after installing the injen cai.
1st: 5900
2nd: 6100
3rd: 6300

I dunno how you guys get such high shift points

MEVI= middle east variable intake for the 4th gen guys

 

im Larry too..but i dont have shift points....

 

Weird when I had my injen installed my shift points went from what you stated to:
1st: 6300
2nd: 6500
3rd: 6500
4th: hangs at 5k rpms and won't gain anymore(fuel cut speed govern I guess on my auto 2k2)but who needs to go 130 more than once

 

Hey Larry, since I installed a Y-Pipe and Cat-Back with intake, I can rev my auto max almost up to 7000 rpm, but I think there is not more power produce at that rpm.

Cheers

AA

 

Almost 7000! We do have a rpm limiter don't we?

My engine made peak hp at 6200 rpm. I agree not much need to take it much higher than 6500. Generally 300-400 above peak produces best et.

 

Yes we do and mine doesn't like me. I have hit it a few times b/c I had downshifted to the gear to race from a roll. Its around 6800 if I'm not mistaking. Matt

 

So can you fell the difference and is it worth the $$? I would like to add additional power to our car but am new to moding Maximas and don't want to screw anything up since it is her car and under warranty!

Thanks!
Travis

 

Yes, I can definitely feel the difference! Is it worth it? For me, yes.

Traction was a problem before additional hp. Now even more of a problem. That's my next project.

 

Just keep your OEM parts!

 

shift points???
hey larry what year is your car... the larry without the injen CAI.
my shift points are:

1st:5000 rpm
2nd:6500 rpm
3rd:6600 rpm at 110 mph
4th:umm.. around 5000 rpm.. at around 130 mph.
i have a 2k2 auto. with frankencar intake and cattman catback exhaust. IF you do have a 2k2... the ypipes are out? or are you talking about the 2k-2k1's.

for those shift points. im assuming your going full throttle...

 

I have a 2K2.

 

it seems to me that the 2k2's shift higher.. those shift points I listed were for a 2k1 auto

 

Hey im larry..and i have a 2k2...without shift points....

 

You must have a one speed automatic. Even 6 speeds shift.

Chinaonnitrous1, I'm the only real "Larry" though.

 

I'm the first larry though.

and china... don't even get me started about MAFs... stop whoring up the thread.

 

sorry.. fine...i have 5 shift points total~! Plus reverse..HA beat that...

 

My shift points:

1st: 6700
2nd: 6700
3rd: 6700
4th: 6700
5th: no shift - hope for no cops!
