Sorry meng, gtr_rider told me to title it that way



Only thing added since the last dyno was a cutout from summit racing, replacing the test pipe.

WEEEEEEEEEEEERD!!!!!

cutout FTW!!!!

 

<----------- Is getting on Summit Racing as he types this.

So, is it LOUD?

96sleeper also saw similar gains when he got his cut-out, pre VQ35 swap, post 5MT swap.

 

oh its loud alright, had to step out of the dyno bay.

 

yoo, at idle it rumbles identical to a 5.0, its beautiful. Yea it gets prety loud when you rev it. During the dyno runs, there was a guy that had just gotten there as I started my first pull, and the dude asked if I was boosted (because of the change of tone around 4500- when the IM really starts to flow), it really does sound like spoolup lol.

To the dyno n00bs, do not be concerned about my a/f during my cutout run. Remember its a cutout, so SOME of the fumes are still going through the regular catback, so it will READ leaner, just like an "exhuast leak" would.

This is the very device I used...

Beware, ground clerance is of an issue here. I havent scrapped it on anything since its at about the same level as the SFCs, but I do go over speedbumps slower and sideways just as a precaution.

 

yea so like, one more thing....

SouthFloridaMaximas doing big thangz :-D

May zee org expect a nice surprise around X-Mas time, bahahah!!!

 

I may have something to post about also,

 

oh shhhhhhhhh-nap!!!!

I was so amazed by the peak #s I completely forgot to look at whats goin on at redline



Sooo, at 6300, I gained 18whp and 15wtq.

w00h00!!! Talk about addin area under the curve FTW!

 

Just curious what were the SAE #'s? IBmyinboxdoesnthaveanydrfsinit


I don't like too much noise, in fact really none (at best MINIMAL) at all. With that said, I don't think I'll be doing this as of now . This is coming from a dude that is thinking about cams vs changing his muffler for probably the same amount of gain .


So, did you figure out was up w/your #'s? Or is this part of zeh .org Christmas gift? i.e. dynoing said VQ35 spacers & polished UIM/LIM/Plenum?

95BLKMAX
Seriously man (all of you contributors), I gotta hand it to you, you've really taken the time to prove/disprove certain myths/facts. Which only adds fuel to my flamethrower whenever we get a thinking otherwise w/o any proof. . .

 

Guess who. I ain't dead yet!

Damn... I get stuck in Jamaica and come back to find everyone from South florida doin big things. I've been cookin up something in secret for a little while now too. It involves boost and an A33. Only problem is I just lost my job. So untill I get another one, cash saved up to continue the project is used for school and bills. I was expecting something to get in my way with my luck... lol

Time to hide for another month or so again...

 

- Im at work bro, I got enough time to post up the stuff and then i go do stuff around here, lol. I'll send em over when I get home. SAE #s are 250.56WHP/ 239.61WTQ.

- Noise is of no concern here. The only time it will get noisy is when you take off the cover plate. As long as that plate is on, and theres no exhaust leak (the paper gasket is useless caca, just lay a thick bead of cooper silicone around the mating surface, let it air dry for a few hrs, and THEN put it on, it will seal with no problem), wont be any louder than a test pipe.

- gtr_rider PROBABLY wont have his surprise ready for Xmas, thats me that has a surprise for then. Hopefully he wont be too far behind me (maybe for Reyes Magos Day? lolz)

- Werd man, gotta love $35 dyno Thursdays. Been there so many times they know me by my gov't name LOL)

 

Ok meng, so about the same gains right..... cams= 650 for debuloz, and ~1300+ for custom tomei depending on what you want...

or $35 shipped for cutout

better yet, COMBINE the two, o0o NOW you got something serious cooking there... and you get to keep your stock muffler

 

But the gains are only seen when the cutout is 'working' i.e. loud as sin

I got a 15$ Saturday coming up, (15$ for 2 runs, but no playing in between)

 

Sheesh you got dynos coming out the ying yang. Good on ya, that curve's starting to look better!

I have a Summit racing cutout also, except mine's modified.. but I'm tired of the manual, going back to an electric. I'm gettin' old and lazy.

Only a few more months (blah I hate winter) and my 3.5 swap will join the mix... can't wait.

 

I seriously just ordered a cut-out from JEGS just because of this thread. Those are AWESOME gains!

 

pretty huge gain from just the cutout. i guess my 3" catback might be of some use for NA after all...

 

hahaha, werdddd..

 

IMO, still would be too loud. Don't want the :attention:

 

hey hey now, I GET CREDIT FOR THIS LOL!, I got about 7-10whp/tq gain back when i was n/a so i suggested that to our man here, congrats dude!! Now lend me your holesaw!!

 

it's for my turbo setup of course, but I'm not about to fab up another catback to use for the 2 months I'm planning on being NA this winter.

 

I have a holesaw

 

I dunno what his catback/test pipe was like, maybe it was restrictive. I'm fairly certain my cutout didn't give much/if any gain over the Cattman 2.5" catback, based on track results. But that is on a 3.0 not a 3.5...

 

Is it me or should you be going a little further right on the tach?

 

Previous= long tube headers, custom equal length ypipe, WSP test pipe and B-Pipe (has an 18" resonator on it, just to note), DynoMax 2.5" muffler

This is all mandrel-bent, so I wouldnt think of that setup being restrictive. Not much of a science after all in making a B-pipe for our cars, its only going to fit one way and they'll all need the same bends. Unless my muffler is restrictive? Meh, that muffler is getting replaced soon anyways, feel like being a ricer and changing it for something else

NMexMax........... stop making fun of my stock fuelcut! Lol. I told him to bounce it off redline every time cus the stock tach is useless in that range

 

Well, I have dyno results closed and open cutout back to back, and I got just as good gains, my catback is 2.5" with Dynoxmax superturbo 2.5" muffller, thats about it.

 

nismology was naggin me, so here's the same graph from the 1st post, but with "comparable SAE #s"...



still good shat :-D

 

/me is getting an electric cutout as he types this.

 

Nice numbers man!


I might see you there...

 

Hellda good! No cutout for me at the test pipe... for obvious reasons.

 

Great progress 95blkmax. Those dumps sure make a difference.

 

BUY MINE!!

 

Read above.


You gonna spray? You post on that forum much?

404 ERROR, In box just checked, no DRF's found.

 

Just did.

 

I'm not even sure that I'll go, but if I do, I might dyno or I might not. If I do dyno, maybe I'll spray.

I don't post on that forum at all. I hardly even browse it. Although, I do know the owner of RSW.

Right now I'm in the process of installing a new and improved engine.

 

VQ35? . . . .

 

No it's just a rebuilt VE with high comp pistons

 

. . . .

 

505max94SE- thanks!
Maxboost925- you can still use the cutout, right after the turbo is where streetz has his. Closed and it runs it through the muffler and its the ULTIMATE sleeper. Open it up and.... Omg that spooling sound with rumbley idle FTW, lol.
Meximax- Thank you! and check your PM
NMexMax- ..... wow, after 5250 our graphs are basically identical! just mine is a bit higher. wow thats insane I finally found a way to match your power curves w/o messing with int cam timing, w00h00! If only I had extended revs to take advantage of it, lol... just think of the gains YOU would have with zee cutout

 

I have a theory, remember?

http://forums.maxima.org/showpost.ph...39&postcount=4

 

intriguing theory, would be interesting to see what my top end looks like on 3rd gear instead of 4th. If it varies at all due to my stock redline FTL

 

I think it's a bigger problem with the 4AT (loooong gearing)
