Test pipe + Helmholtz delete (replaced with a 3"ID pipe knight_yyz's)


1.) I set all AFC settings to 0. It was thick/rich as you can see. Still put more down vs the last time.

2.) Leaned it up a bit. (-6-8%).

3.) Leaned it further, more so on the 5-6k range to hopefully indirectly add timing to manage the camels hump. (12-15% in the 5-6k, and 10-12% everywhere else.

4.) Decided to lean it more. -14% pretty much all around, except post 6k, was about -8-12%. Same, nearly identical within a 1/2 hp.

5.) Richened it up a bit, I think she was getting mad though, nothing changed, another nearly identical run.

As I suspected, the curve develops the camels hump in the 5k range due to the straight pipe. But, nicely adds some hp at 6k.

The sound is amazing.

Last time vs this time:



Best & worst of today:


See the AF, rich as shyt with 0 corrections:



All runs hp w/AFR:



All with torque and AFR:

 

Nice... I'm going to dyno next week. Hope for the 260 lol.

 

Is that a record N/A whp for 4at 5.5s?

 

For a dynojet no, Aaron holds that record @ 270+. Although, he is in a 3rg gen chassis. So maybe, yeah, for a 5.5 gen chassis, 4AT.

I need cams and a torque convertor.

 

Good numbers cant wait to get some headers....Cattman of course...

 

Are you able to change the rev limiter on the emanage ultimate??

BTW nice gains to the OP of the cat delete and the piece of pipe on the intake... I think you should reconsider the 3.5SRI and the LRMAF

 

I suppose it might make more. I have all the hardware I think I need to piece it together.

The only theoretical bottle neck is the JWT POP (76.2mm)

My last LRMAF (82mm) dyno was 242/238.

The latest have been with the 76.2mm ID.

Here's the last intake set-up, ub3r short SRI before I switched to the 3" ID.

Filter/LRMAF/TB. This netted 242/238, but this was pre-spacer/3" catback.

 

Nice numbers! Def is putting down some power! Any videos?

 

 

You should consider a correct length SRI with the BPI 3.5 Velocity so there wont be no restrictions I bought most of my 3.5" hardware from siliconeintakes.com to see the real gains from the 3.5" intake

 

What's the correct length?

Whens your next scheduled dyno?

 

What (Sparks) said like 31" including the TB and elbow of the IM

Not the super short SRI

 

Shorter than what I have now. I'll need to look into that website for some possibly needed hardware.

Seems easy enough to do with an LRMAF.

Been reading on other forums and such with cars of similar whp, and most cars with anything above 260 on an intraweb dyno seem to have a 3.5" intake. (TL-S, etc)

There are a few select Maximas on here with the exception, but I'm not ready for cams just yet.

Looks like I will piece this monster together this summer.

 

I wont be going to Dyno anytime soon but I know for sure my car should be close to the 260whp mark because of previous Dyno and mph at the 1/4 and mph increase from mods after last Dyno session For me its more fun and cheaper to see the improvements at the track Next I will be testing a 3.5" elbow on top of the SSIM to see if there its any benefits from it but at the track. I wish I could get some kind of reflash without the hassle of rewiring a UTEC or changing to a newer type of ECU jut to get my rev limiter moved to 7100rpms ;(

 

Like I said somewhere, the best DA ever here, well at the closest track, was 1695 and it was 1-5-11, temp of -5ºF/31in/Hg. <-- That would never happen during the season. It's typically in the 7000-8000 DA range during the season. So I prefer to dyno .

What was your last track time & trap? Has anyone ever looked into the TS flash working for your car (first gen ECU L31, from what I recall)? I bet they'd still be a PITA to obtain since people either hold on to them or just don't have them anymore.

What have you done since your last dyno? All it took for me was a test pipe and a different intake set-up to gain 10whp, so yeah, pretty easy game.

 

After my Dyno I did the SSIM and the 3.5" intake and LRMAF my PB after Dyno was 14.2 @ 97mph after SSIM and 3.5" intake and LRMAF all things being equal (no weight reduction) 14.1 @ 99mph but my best ET at this time 13.96 @ 100mph no back seat and pass seat.
I think the only option for reflash was TS but I think they wont be doing this anymore I heard some rumors that JWT may do the reflashes like they did but have to confirm this...

 

Ya I know TS went under. But you haven't seen anyone selling a TS? Like, maybe people that upgraded to UTEC?

Do you know if the DA's were nearly the same? Damn, I need to try this new 3.5" intake deal.

Yeah, that 4AT + 6600 rev limiter aren't very nice. Have you tried smaller dia. wheel/tire combo for beneficial and effective FD ratio?

 

Great numbers man. Your car really is putting out some strong numbers for the 5AT on the VQ35DE. I think with a 350Z IM you could potentially see even higher numbers, and add to that what an MREV II can do. I personally saw an '06 AT 350Z put over 270 RWHP on the same dyno I dynoed my Maxima.

 

I wish to God I had a 5AT.

If you mean including reverse, then yes, it is a 5AT.

I'd rather piece together a 3.5" intake with this existing IM vs doing all the jazz required for the MREV and such.

What type of dyno was it and what did your car put down?

 

I will send you some pics of my custom elbow once its finished...
But I hope it work I not I will look nice at least jejejejeje

 

I meant 4AT. Doh.

It was a dynojet. That was 2 years ago almost exactly and I think it was around 102F outside. My car was 100% bone stock at the time and dynoed 200 rwhp, 210 rwtq super heatsoaked from a 40 minute drive and literally driving straight on the rollers.

 

Don't know where you live and all the DA situations where you live but if you put 260 to the wheels even a 4AT, shouldn't those times be like a 13.6 or even lower....but don't know where you live since they say the girl SexyLeo dynoed at like 247 and busted a 13.66 ....but who knows....

 

He lives in "Location: Espanola, NM" and DA sucks.. He should still run and see the corrected times

Sounds good btw!!!!

 

That means nothing I used to have a B13 Sentra that ran 13.7 with 160whp??
What was SexyLeo weight at the time of the 13.6 pass??
What were the 60'ft?
You have to look at the complete variants of the difference on the ET's to judge the difference...
I dont know the D.A. but all I can tell you its that temps are in the mid 80's and 30% humidity thats the price of living in the tropic jajajajaja
Go to salinasspeedway-pr.com
But its all good for me....

 

Not sure her weight and all think 2.1 60fts....but not sure what mods do you have on your car now for those 13.9s.....

I think he meant Payu? But yeah, 7000-8000 DA's here around this time, since the actual "DA" is already 5000.


That's how I do mine. It's a 1:45 minute drive, and she gets straight onto the rollers too.


I'm guessing your 200 FWHP was SAE or even STD corrected (higher than SAE if the RH is above 30%), as was the Z33's.

That sounds about on par for a 6MT, and a bit high for a 4AT.

 

record dyno times for a 5.5 auto is 264whp set by cant get ryte down here in MD......... i need to throw mines on the dyno too... hopefully i can get another AF controller and somehow put up 270's

 

And you know Nmex got a Dyno in his garage....j/k
Maybe a mistake I thought she had that 13.66 time maybe somebody else

 

That was a Dyno Dynamics and those all depend on how they're set up. Not taking anything away, but they can be set up to read anything pretty much. Also, I'm sure his TC helped that #. Something on my to do list.

A 6th gen went on one of those and hit 260, got on a DJ and hit 234. And of course, we've seen it break hearts where someone got 230 on a DJ, and got 190 on a DD.

DD's/Mustang Dynos are load based and need to be set up correctly in order to read correctly, and either way, they are apples to oranges.

IMO, load based dynos are best for correct tuning since they apply load according to speed, whereas a DJ just calculates the time it takes to accelerate a drum.

But this is why load based dynos need to be set up properly and parameters need to be taken into account (coefficient of drag, weight, most namely.) Cd has a lot to do with the front end of the car, aerodynamics, surface area, etc.

I think she did get a 13.66, but it's hard to find her because her account's been deleted and it wont work in the search criteria. You're correct though, IIRC it was 13.66.

Most of these cars putting down somewhere in the 230's.

 

Yeah those cars are in the "230's" but you have to take in to account the weight of the car with driver at the time they made those passes to compare to another car running slower with more power I am pretty confident that those cars were pretty glutted at the time they made those passes or by any chance a 2003 Altima SE with a 270lbs driver its just heavier than those cars with their respective drivers and I dont have 60ft times either to compare with those passes but they wont be lower than 2.1 for sure on regular street tires no DR or anything its just physics jajajajaja
http://forums.maxima.org/1-4-1-8-mil...onditions.html
For example this a car with probably 240's whp ran 12.9 @ 106 and then with a higher wieght and poor track conditions and regular street tires it ran 13.9 @ 100 just to give you an example

 

So what state are in? And do you gut anything for the track, and what mods are you currently running or is it classified ....and Auto or 6spd......

 

Just ordered a 3.5" 45º pipe from siliconeintakes and a 3.5" BPI from, well, BPI.

I have plenty of couplers, an LRMAF, and a 6" ID filter.

 

Good you must break the 260's with the new intake for sure according to recent discoveries jajajaja....

 

I would imagine I will be dynoing in 2 weeks after the install. (week for it to come in, and dyno the week after).

 

Do you have a hookup at a dyno? With as many pulls as you've done I'd say you've spent a grip of money just at the dyno alone. Although I do think its awesome you have been so thorough with your testing as its really shed light on what helps to get the most out of these engines.

 

Don't get me started on that.

But actually, yeah, they're cool with me. The second to the last time I scheduled, they couldn't get me so this past time, he only charged me for 3 pulls and I got 5. That happened a few times ago too, I got 7 for the price of 3.

 

nope

nothing to take away, youve pretty much mirrored mod for mod what i have outside of some of the new stuff . and im sure the TC helped lol. that was the purpose for buying it.

 

New 3.5" intake set-up. Cant give any quantitative evidence of better flow because the MAF is seeing less. I'm going to wait until the fire is out and after the holiday to re-dyno/tune.

I needed to add about 20-22% fuel to get a decent street tune for 13.0-13.5. Was running really lean (15.0-16.0)


Timing is the same so the addition of that much fuel/voltage didn't seem to affect it.

Airflow went down about 10-12%.

 

havent installed mimne ye. will be waiting until after the porting and honing to go about a full on install. been trying to get ahold of aaron, but for some reason have the wrong number.

 

Good info. I will be doing a 3.5" intake setup on my Z soon. I didnt think it would lean it out that much. You're using the same MAF and just bigger piping right? Also how did you make the intake?
