Gutted Pre-cats Dyno run
Yes I know, its another gutted pre-cats thread, but this one has pictures of squiggly lines on a paper with some numbers all over it. 
The car made
226.13whp and 227.50tq on a 2nd gear pull
234.17whp and 246.31tq on a 3rd gear pull
Power Mod list is as follows
Gutted Pre-cats / Warpspeed y-pipe + test pipe / Tsudo 2.5inch mid-pipe / Megan M-DT muffler / Berk intake with Apexi Filter / BOP plate / 2* timing advance
What she sounds like
The 2nd gear pull

Yea I should've taken it to the dyno before doing it, but ended up gutting the cats without even planning on doing it lmfao

Only in the sense that it doesn't show a quantitative analysis on gutting the pre-cats. Other than that, you had fun, right?
Exactly. You'd probably get near 240 hp after installing intake spacers. But I think to get near 250, you'd need to actively tune the car, install headers, a 3" exhaust, etc. And there are other things you can do that are power-mods, but don't necessarily manifest as HP. The Torque-Link, for example.
Either way, I bet you're happy for the moment. Enjoy it.
OAN... Sheer Silver SE, eh? Looks familiar.

Yea I did have fun, and I'm happy with where its at right now 
I will probably be able to stop myself from buying more mods for about a month or so, and then I might have a NWP shopping spree and do a 3 inch cat-back
hahaha, sadly its no where near as clean as yours is

So... much... rasp. If you make any other changes to your exhaust, just go with a 3", you won't be disappointed.
The numbers look good, but do keep in mind that numbers will change from dyno to dyno (or even operator to operator), so where you get 234/246 here you might get 195/210 (or 250/260) somewhere else. The best use of a dyno is to test changes and tune in a controlled environment.

........I love the exhaust note and the way people's heads turn when I start the car, nobody expects it from a maxima
Not to mention, the drone does wonders when you got a girl in your car that won't stop talking
I drive an auto maxima, I laugh to cover up the disappointment

Yea I know that, but for now I'm just gonna believe these numbers, but I'm 100% sure within 2 months I'm gonna be back on a dyno with spacers and a 3 inch exhaust getting the car tuned SMFH

When you add those mods, make sure to go back to the same dyno and tell them you're wanting to compare to previous runs there... Then you can use those dyno numbers for something worthwhile

Nice numbers!
If you get a 3" cat back, Spacers and and UD pulley you will have significant gains. If you are getting a tune go with LRMAF and 3.5" intake with the 6" Vstack and AEM filter. The 3" catback will sound ALOT better and whole lot sexier!
Nothing is wrong with an "AUTO" Maxima.
PS: If you get a JERK cop they will pull you over for that WHITE LED in the rear sidemarker....just fair warning. Its supposed to be RED. I learned from experience.

That was the most boring video I've ever watched.
With spacers you should "feel" the gain a lot more everyday than a mod that puts power at the top. Either that or headers, but it seems there are no OBX headers available at this time and maybe never will be. So the price difference between Cattman headers and spacers is huge. And a cattman exhaust won't make it raspy at all. I've got a BRM exhaust with a smaller resonator and muffler and it doesn't rasp at all.

I didn't imply that it was directed at anyone. It's stereotypically funny nonetheless. BTW; I wouldn't consider it self-deprecating humor at all. Since your opinions are always substantiated by knowledge of the subject matter.
