He doesn't have a 6 speed, and I'm not certain he's reached the 300chp mark at this point. However he'll get there soon Im sure.

 

whats the big deal about this chp figure? I guess some feel there car sounds faster if someone asks them how much power they make and they can say 300hp. I haven't seen a 3.5l Auto put down over 240whp so using ricer math that has yet to be accurately determined there aren't any Autos in the 300+chp range. My old Auto made the best of 236whp but I didn't go around telling everyone my car had 300hp.

 

There are some auto Altimas in the 240-250 whp range, I'm not sure what corr. factor they use SAE/STD
I hope to be there soon as well .

 

So basically, intake, headers, catback and emanage? How do u know he put down 310chp?

 

Well it jus makes sense to quote chp since that's how cars are rated from the factory, that's what most people understand, and that's what gives a good picture of how much more powerful a car is modded over stock. I'm sure if you tell someone ur car dynos at 240whp they'll look at you like u had three heads. Tell them that's b/w 289-307chp and I'm sure they'll understand! lol
Did u have SR's SSM when u dyno'd that? If not, I'm sure that'd more than get u past 240whp on ur auto 3.5.

 

E55 is auto ...

can't put down chp .. olny put down whp ..

 

When u say old auto I'm assuming it's an auto 5.5 gen and not that boosted 4th gen in ur sig?

 

He had as blue 2k2, and now he has a 96 S/C...

 

I know, but I phrased my question according to his statement. Notice he said "put down"? Ok, how's "put out" 310chp? Better now?

 

You mean "only"? See, this nit picking at syntax gets us nowhere.

 

this thread can't go anywhere either until someone pulls the motor and gets the actual motor dynoed. This thread seems sort of pointless IMO.

 

Just like its sister thread in the 6th gen forum.

WHP, IMO and to me, is more important than advertised #'s. We all know our engine put out more torque than the claimed 246 crank figure, and we know this by what we put down to the wheels. ....

 

Agreed. Although the chances of that happening are slim to none, that's why it's useful to attempt a close guesstimate of chp by extrapolating it from whp.
All I was tryina say was that there's no reason a manual 5.5 gen can't be putting out over 300chp if it's dyno'ing over 250whp.
If the 5.5 gen manuals really are putting out the rated 255chp and they're dyno'ing around 205whp, then using the same dt loss would net ~312chp if dyno'ing around 250whp.
205whp / 255chp = .8 dt loss 250whp / .8 = 312chp.
Similarly, even if the 5.5 gens were only putting out 245chp, that would put one dyno'ing @ 250whp at 301chp. 205whp / 245chp = .83 dt loss. 250whp / .83 = ~301chp.
That's all I was trying to say, but apparently many of u here don't like that assumption so to each his own. Thanx for your time I guess.

 

If any good came out of this thread I'd have to say it's that the original poster got his questions answered quite decisively. Those answers being any combination of at least 4 of any of these mods: intake, SSIM, headers, catback and a/f/ignition tuning. And that it is more than possible to be putting out 300+chp. But since there's no universally accepted way of measuring chp w/out an engine dyno, he wouldn't really know if he reached 300chp without dropping his engine onto an engine dyno, which is likely beyond the resources of most people. (Hence my attempts at estimating a reasonable whp to chp conversion.)

 

But like u said NMax, without knowing for sure, it's useless trying to calculate chp from whp. I'll remember that when I come across any estimates of 1/4 mile trap speeds, times, 60's, 0-60s etc. given certain mods, variables etc. Thanx for your unique view of the world.

 

And for the most part I agree with you. I only find converting whp back to est. chp useful when trying to determine the actual chp output of some of the VQ35 applications out there, since we all know how screwy Nissan's hp/tq rating is w/ these engines.
In what world does 220whp amount to 246chp??? More like 265chp.

 

you are such a post *****...geez

 

Sheesh...lighten up guy. DuceyDuce got his answer didnt he? I didn't mean for it to get out of hand like this. Thanx a lot.

 

NmexMax, the safc-II is great. Have fun tuning with it. Hopefully you reap the same benefits i did. You can get them brand new off ebay for like 250 shipped

 

Thanx for the price eckohb. At least someone tried answerin me. How do u think the SAFCII compares to the VACFII? Which would u recommend someone get if they needed a tuner? I'd also love to be able to view a/f ratios maybe even spark timing in real time. Any products out there do this? I've searched but unsuccessfully cuz I didn't know wut I was searchin for. lol Any input appreciated!

 

Apparenlty you haven't searched that hard .. this was brought back from the dead in the 4th gen forums 1st page yesterday ... and today it still remains on the 1st page ...

Search sleaze for SAFC.

I found mine locally for 200

 

I meant I searched on google, but since I didn't exactly know the name of what I was searchin for it wasn't very useful. I'm not able to search the .org cuz I'm not yet a donating member. Next $20 I get will go to that promise!
Are you telling me to search "sleaze sumthin" for results on SACFII or are you telling me to search while calling me sleaze sumthin? Thanx much if it's not the latter!
Thanx, I hope I can find one for around $250.00 or under. Did u find it at a specialty auto parts store? Store chain name would be great if you have it.

 

sleaze = ebay. My reed way of saying it. tard = for clarification once again.

I found it from a local private sale.

Well, that thread was on the 1st page of the 4th gen forum, so I figured you had seen it, since it was there yestrerday and today and you have a 4th gen.

I searched ebay and found a few for 220-250 + shipping which was typically ~ 15$.

They have a few for ~ 120 or so the black model case(SAFC-II prior version). Only offers 500 rpm adjustments instead of 200 and also doesn't have the knock sensor wire option.

 

Oooohh...lol funny! That's cool. So I'm guessing ur pretty happy w/ it huh? Any regrets? Would u buy it over again before the other similar devices?
I'm looking for something that'll allow me to monitor sensor data such as a/f ratio, spark timing, etc. in real time, and if need be, even adjust them on the fly. Something pretty close to the Nissan Consult but for consumers.
There's been mention in that other thread of something that can do this but I'm waiting for more replies on it. I posted this same comment in the thread u told me bout and am currently awaiting more info.
I believe the current SAFCII adjusts in 200 rpm increments so that's what I'll be trying to get. Maybe it's the SAFCI that adjusts in 500rpm increments?? Thanx for your input though, you've been a great help!

 

What's the knock sensor wire option do, allow for monitoring and/or adjustment of ignition timing?

 

monitors the knocking, not ignition timing. Need an smt-6 or 7 for that.

 

gotcha! I don't know anywhere that sells the SMT7 do u? I was lookin at the SMT6 but the 7's caught my attention w/ the spark timing control.

 

I dont think smt-7 is available right now, IIRC. SMT-6 would be good to use, if thats the route youd like to go.

 

What do u use to adjust a/f and ignition timing? I'm thinkin I'll jus get a SAFCII and wideband O2 for now.
I can figure out how to tune the timing later.

 

SAFC-II is just a/f

 

I know, that's what I meant by finding out how to tune timing later. (Since the SAFCII doesn't do it.) Is that what you use?

 

smt-6? yes. Or just get a JWT ECU or TS ecu, which is what i will be doing because i want the ext. rev limiter

 

I meant SAFCII but that answers my question anyway thanx. I can't afford the super extended down time w/ out my car since it's my daily driver and I don't have access to spare ECU's and I don't yet need the ext. rev limiter so I'm stickin w/ piggy-back style tuners, at least for now.

 

The way things stand right now, you be better of with a JWT ECU, I was down for 30 mins since I found a cheap ($65) core to send in.

Do a dyno with the JWT, and look @ your A/F after that and decide from there whether you want or need to tunre your a/f.

Timing, right now, is only adjusted through the JWT/TS.

 

Why would I be better off? Why only 30 min.? Where'd u find ur core? So you sent in the cheap core for them to modify while you drove around w/ ur stock ecu?
I plan on using the SAFCII b/w mods on my current car and my next one so it's much more useful to me than a proprietary Maxima only ecu.

So no1's currently using the SMT6/7, emanage/emanage Ultimate, Unichip or anything else to adjust timing?

 

Anyone who uses JWT products will get what they deserve. Everyone should know by now to avoid that company like HIV.

 

roflmao!!!

 

So what do u use SR?

 

http://www.technosquareinc.com/limited.htm

I have an L-Spec ECU from TS. No new software, no frills. Just an OE based MAP to 7500 RPM.

 

it says 7100 on their website. did you make a special request for 7500?
