i don't know, it's all kinda speculation.

That nissan tech said he heard the stock engine can run up to 320whp with proper tuning

I'm not sure what to think of that.

I hope to gain around 10whp, but mainly I just want a flat fuel curve and it to stay flat. Hopefully that eliminates my misfiring my car has and don't trip SES lights every other start up.

So I'd say the range I'm hoping to gain is 0-30whp.

I don't really think I'll gain 30whp, but it might be possible based on the nissan engineer's words. However with adding power, it isn't 1+1=2 math. It might be I've already gained most of that potential power he says you can gain.

TS and AAM flashes gain power, but I think after a certain point with bolt ons, the MAF sensor gets saturated - actually I read that it easily can get saturated, and that was one of the 1st things FI kits overcame.

So with enough bolt ons the MAF gets saturated and the O2 sensor detects worse emissions than expected

 

Yeah, it's definitely not 1+1=2 math, unfortunately I guess keeping it consistent is really the important thing. But, considering you've spent so much in NA mods, a 30+whp gain would be real nice ALthough reliability shoudl eb on your side, I would still expect a 150hp gain or more after spending that kind of dough.


Very interesting. I never heard of this. Neat info. But, how did the FI kits overcome the MAF saturation though? Because they are built somewhat emissions friendly?

 

I thought all the FI piggybacks adjusted A/F with voltage settings for the MAF.

I don't think the greddy Emanage works that way though....and greddy kits have probably blown more engines than any other FI kit right?

 

awesome. thanks for the links sentry.

 

KwikZ - I noticed in your tagline that you've got an 01 Silverado 5.3L and a Durango 5.9L with "All the boltons" as you mentioned..

Did you really expect to see big V8 torque out of a V6 engine that's like 40% smaller? The Z is not just about straight line power. Why don't you take your Durango with "Bolt Ons" to the track and I'll take your Z and we'll see who gets better lap times?

Dude, if you wanted to "Take people off the line" you should have saved your money and picked up another redneck-mobile like a duster with a hemi...

 

you misunderstood what i am trying to say here bro i am not comparing, im just angry at nissan for making a sports car that cant be moded safely ...

look with out the luxury of a tuning software what ever mod you do even soft mods like cold air can affect your air/fuel ratio or timing you can even blow the motor... nissan has chose to not let me mod my car safely because the computer wont compensate for mods nor will they let me buy a program to do my own custom tuning because they wont share the codes with anyone.
man if i had a tuning program i would be all over that twin turbo deal rite now

with my truck i just connect my laptop to my truck when ever i feel like it and start changing or deleting things..thats why its safe to add a blower or what ever you feel like adding to your pride and joy....

i have had my radix supercharger on my truck for a year and a half with out problems why??? cos i can play with the PCM to make the truck accept the new mods...

i cant think of any other sports car that has such a complicated manegment system like the Z

im sure the nissan people read these posts all the time and my message to them is........

WHY HAVE YOU CHOSE THIS TYPE OF COMPUTER FOR YOUR SPORTS CARS???I CAN UNDERSTAND IF YOU DID THAT TO YOUR TRUCKS AND REGULAR CARS BUT WHY TO YOUR SPORT DIVISION
DONT YOU KNOW IT WILL HURT SALES AND MAKE THIS CAR LESS DESIRABLE AND EVEN LESS COMPETITIVE....

 

If you lost to a 300C you need to learn how to drive bro. The problem is you, not your car. A stock Z with a half decent driver should beat a 300C, I absolutley murdered one on the highway, even gave him a nice jump. Look at the link in my sig, if you dont think my bolt-on times are "quick" for a Z that is, then you need to trade your car in for a Mustang or an SRT-4 something with easier power potential. My Z with less than $2000 in engine upgrades has trapped 7mph over stock....do some homework before you come on here making yourself look dumb.

 

+1

 

13.1 @107 on such a few boltons wow nice thats corvette territory bro..wish i could get a pcm flash

i am a good driver with a bad car is all.



heres what happend with the 300C lights turn green we go...

first gear- im slightly ahead

second- his at my door

third- still same place but he started to slightly get an edge on me

fourth- for some fu%$%$ing reason the Z looses the fu^&ing pep he starts to pull on me so i immediately slowd dawn



oh yeh and to all you keyboard worriors out there be nice ok...

peace

 

The car is 240 whp stock. 320-350 hp with a FEW mods?

What a tool.

 

Are you sure you are not having any problems with the car. 3-4th gear you're right in the powerband and should be pulling hard ... maybe you should check into it.

 

yeh i can smell a heavy odor coming from my exhaust think my Z is runin rich.

i got about 3K miles on the Z so im hoping it will get better after few more miles

 

Happens under hard acceleration. There was a thread about this about a week or so ago. A lot of people smell odd scents after WOT. I smell electrical fire. LOL

Do you smell burning feathers? Beavers and ducks!!!!!one!!!!1!!
(you'll get that if you've seen the movie Bandits)

 

nah it just smells like unburnt fuel

 

that's your test pipes

 

Are you referring to O2 simulators? Where did you find some?

 

Use non foulers. Do a search for the help method.

 

Um, you do realize that there is a 300C Hemi w/ 340hp and 390 lb-ft of torque, right?

 

Armitage.. That's the slow one Chrysler 300C SRT8 425HP/420ft-lb 0-60 4.7. Heh.

 

^Ok, well I stand corrected then. That would smoke the Z in a straight line.
