5.7 Gen 1st dyno run Baseline, STOCK 250 hp

Well, I dunno, but just telling you my personal observations.
I know SR20DEN and 6Spd_Hayes both dynoed with a ported air box (~250)and stock airbox(non-ported) (247).
I just think the 3" + headers really make an intake a good thing, sort of compounding the effect.
I say torque is probably a combination of timing and EVT/IVT.

Hmm ok. We shall see. I'm progressing to the next steps.
#1 Tuning system
#2 back to dyno for baseline to check if things are better (not dyno tuned)
#3 injectors/ fuel pump
#4 intake system
#5 dyno adjustments for new parts, possibly some tuning
#6 full dyno tune or adjustments of parts
#7 hopefully close to my 300 whp goal
on a side note, i MIGHT have a slight exhaust leak i really cant tell. It might be the funky EVT. Thinking of pulling the headers and getting them coated anyway. Bay heat is quite hot.

Ohh yeah!! haha its not going to be in the next week tho! Bout to jump back on the z ecu swap!
Oh ok is cylinder 2 ok? ill strip the harness and have the black wire out of it. For quicker rpm hookups! thanks!

Reason being is because I noticed on the DRF, the loss of signal on the tq curve on a few runs, happens when you clamp all of the coil wires together for some reason.

Very good info! Thanks!

hes gotta lotta factors to weed through. thats pretty much a baseline to start working issues and developing his tune from there. hell be much better with the cam timing issues sorted, and once he gets control on the other parameters.

Of course a good tune is going to help a lot too.

Thanks! me either!!!! this is the most fun of the whole build!!!
Yeah i thought it would be more. This just proves the 02 ecu SUCKS. haha and i think EVT not hooked to anything is messing things up too
Exactly!
Idk really, i still think its EVT thats throwing it all off.
Im planning to run the rev up ecu. And re dyno. See what a stock good ecu can do.

It is what it is. Its decent . But its not running right. So my plan is to get it running with EVT. And see get another baseline with it working. Hopefully itll look better!
Hope to be back at the dyno in a few weeks!

I drilled a hole in the pipe and used one of these. You can pick up a brass one at Homies if you need it asap.

I cant remember what bit I used but drill it just a hair under and screw that bish in. The soft aluminum created threads on the spot. Sure it may create a little turbulence inside but dont thread it in very far. You can put some clear silicone around the outside if you are concerned about leaks (I didn't and don't have a leak).

Yep, that's all I did, sorta. I used a PVC barb and sealed it in the Lowe's hardware coupler vs drilling a hole in the Al tube, but, it's probably a better idea to do what Reizy did. More reliable.

I think 250 untuned is excellent. My run with headers and no tune was only about 230/230. With full dyno tune we got that up to 254/249.
I'm sure with a proper tune and a good AFR you should easily get 270-280 at the wheels.
If you need an intake I do custom build them. Any length you need. Breather tube any size/length you need. I believe I have piping with a 90mm od and 3.0 wall which would make the ID 3.3" I will check what's available at work and get back to you. The hard part about a 3.5" id is that it will be hard to get couplers to fit the OD. A 90mm coupler is easy to find.

Yea the more i think about 250 untuned it does seem pretty good.
Cool id like something but its gotta be the 3.5 od pipe. Ive found it and couplers from siliconeintakes.com The only prob is the pcv hose. But ill use a barb fitting prolly.
I believe the 3.5 intake , along with lr maf, and v stack will be what this motor needs. But seeing its running lean now, im thinking its gonna really like some added fuel along with this intake.

i'm going to check and see if I have any pipe with a 3.5 OD, and a thinner wall to increase the ID
BTY 90mm OD is 3.54 OD so if you are really picky I could machine 1" length at both ends down the extra .040 inches

ohh sorry all the metric and standard crap is annoying.
If you can do a intake close to 3.5" with the MAf thing built in and the pcv built it then ill def buy it.
I just got the wrong size lr maf and i need to return it anyway.

Why don't you just get 2 breather filters, put them on both valve covers and delete the hoses?? then you wont have to drill holes in the intake. JIME said he has been running his maxima like that for years and no problems...I also seen SPARKS had breather filters on too....unless you concerned about the gases going into the environment?

Yeah ive been thinking about something like this. Idk if its just simple as putting 2 breathers on the pcv, front and rear tho. Ill have to lookinto it!
Thats a nice pnp utec you have in your sig!!!

I looked at it and it looks like the one on the front you can just delete the hose and use the intake tubing and put a breather on the front valve cover. The one in the rear looks like you can put a breather on the rear...but you would have to cap the hose connection to the IM. I know when I put my BOP on it was ashame how much oil was just sitting there in the IM. I don't know if the new VQ engine is the same...but that is how the 02 is.

Oh ok, i knew the front hose could simply be replaced with a breather. (problem is on the 09 valve cover the hose is towards the middle, not on the end like the 02)
But the PCV valve it self can have a little breather on it also? id cap the IM port ofcourse. But i didnt know it was that easy. hmmmm
I think the 09 had a VERY small amount of oil in the IM from the pcv. its natural i think.
Thanks!! Post up a dyno thread when your tuned!

While I was looking at your thread those ads were at the bottom so I guess the answer to all your problems was the 179.99 supercharger 
In all honesty though I think your dyno numbers are really good! think about it the motor is rated at 290 hp and you were able to put down 250 whp with no tune, using your 02 ecu, vias connections screwed up, etc. With a couple adjustments and tune you'll probably be around 290 at the wheels.

FWIW I have the crossover tube and a breather on both new '05 valve covers. I punched out the PCV valve so it was open, then clamped a breather filter on both valve covers. It's been that way for a few months. I got very tired of oil in the IMs, so when I converted to the 08 Altima IMs, I did dual breathers.
OK cool sounds like this is the route ima go! Maybe there is a little power in this also? idk

ohhh ok haahh
Yeah im hoping to have all that sorted out very soon, hopefully this intake will really have a good hp gain!

mmk... sounds about right for a regular 3.5 swap.... with a 2.5" catback ppl are maing mid 240's so i can see 250 with a 3"... cant wait til u fix the issues.. with your mods i was kinda expecting 260's maybe low 270's

Remember that im on a stock intake, just with K&N filter and "gab" mod. Also my ECU pulled timing like crazy.

well even with a filter the is still similar gains to a short ram... now as far as the ECU retarding its times, thats no good, thats why i cant wait til thats fixed
