250.92 FWHP 240.59 lb/ft TQ

[knight_yyz]

Well here's what you have all been waiting for. You've seen the list of mods, and If I'm not mistaken, I believe I am the first to post the results of cattman generation 3 headers with a dyno tune. Mike at DL Motorsports was able to squeeze out an amazing 250.92 FWHP and 240.59 lb/ft torque!!!!!!! :reallyshocked: The car pulls like a mofo now. So without further adieu, the much anticipated dyno graph.... BTY the temperature was 84.33F barometric pressure was 29.56 in-Hg and humidity at 15%. Sorry I can't show that on the graph because I don't know how to use the software yet. If you want run files pm me and I'll email them to you.

Fantastic #'s. Do shift the curve to the right, and send me the runfiles, and not in that order.

Sweet man. I guess I should just stop trying to 'hang' w/ the 6MT's

[knight_yyz]

sorry but I have to ask... how do I shift the curve to the right? And bty before anyone asks I don't have AFR but If I remember correctly it's 12.2? I'm using winpep for the first time and I don't know how to use it very well. I can't display the conditions and max numbers at same time. So I will just type them in. 84.33F 29.56 in-Hg 15% Humidity.

You'll have to excuse Nmex's humor

[ajcool2]

Do you have #'s before the headers?

[Zack342]

what are you mods those are some sick #'s

[knight_yyz]

ah ok, I know nmex likes to joke around, but I thought he was being serious this time.

My mods are gen 3 cattman headers, cattman catback, underpulley , and a custom short ram intake. (ie I made an aluminum tube and stuck the maf and adaptor and filter on the end of it) tuned with greddy EB (afr and some timing advance)

208/220 was base run, stock with injen intake

[knight_yyz]

bty, dandymax installed the EB for me, he mentioned there was some debate in here as to whether or not it was possible to advance the timing with the EB. Mike, who did the tuning said he did add a little timing here and there. Once I figure out how to use the EB software I will try to post those numbers as well.

[Zack342]

EB= Emanage blue? Dude your numbers are amazing for your mods. You picked up 42whp roughly 20% increase in power. You maxima must fly.

Makes me wanna get rid of my G and get a maxima like yours

[knight_yyz]

yes emanage blue. I need wider tires for sure. When I left the shop I was rolling at 20kmh then stomped on it. Tires broke loose so I let up. Got going a bit faster and tried again, still broke loose. Basically I can not put it to the floor in first gear at any point without the tires spinning . Looks like Brian's 3rd gen headers are the best so far!

[LA02MAX]

my god...you picked up so much area under the curve. I WANT HEADERS, DAMNIT!!

[opanick]

i have the same headers sitting in my living room just waiting to be put on, i hope I hit numbers like this

[knight_yyz]

phenolic spacers next...

[Zack342]

I want an 03 maxima

[renman]

Nice numbers from a TMEC member!

[clborden]

DAMN!!! Looks like these headers were well worth the wait. Incredible numbers. Congrats!

Gotta give Brian serious props.

[NmexMAX]

I didn't think you could get timing advance from the EB? Only retard.

It can't on VQ30's? Maybe it can on the 35

[knight_yyz]

Once we had the car strapped to the dyno, I told him about the vias, 1800, 3600 blah blah, then asked him if the timing could be advanced. We did a partial run in 4th gear to make sure everything was working. Then at idle he advanced the timing 5* and the rpm's changed drastically, then he retarded back to "stock" then retarded another 5*. The rpm's changed everytime.

I have the EB software on my laptop but do not know how to use it at this point in time. Is there a way I can use my laptop to check out the settings he used? I don't think he added too much timing, he was aiming for a safe 12.2 AFR so he didn't have to play around too much.

[NmexMAX]

12.2 is way rich, too rich for these things.

[knight_yyz]

well it will have to stay that way for now. I'll go back in a few months. How much power will I gain if I get closer to 13/14.? I'll call the tuner on Tuesday to confirm that number though (12.2)

[NmexMAX]

Every car varies, so only time will tell re: AFR gains.

I'm interested in seeing if he actually advanced the timing using the EB, and if so, by how much.


Do you ave the runfiles yet?

[knight_yyz]

i thought I emailed them to you already, but I'll send them again

[nismology]

I guess the dyno guy knew something that SR20 doesn't.



Kicka$$ numbers, BTW!

Says who?

Depending on VE, you can generally get more hp from timing than you will from a lean afr.

In certain rpm ranges, I can get close to 5 degrees more timing at 12.5 than at 13.5.

In my dyno experience I've noticed that my A33B gets very picky whenever there are large fluctuations re: AFR. Also, I've seen, again only in my dynos where my car makes more power whenever it is closest to 14:1. This could be because of the indirect affect of AFR conditioning via MAF V alterations.

I’ve tuned anywhere from 12.5 – 14.0. And 14.0 seems to be the favored area for power production. But again in my case, whenever I go leaner, my timing gets bumped ever so slightly.

So in the end, forget what I said and do what makes most power for your particular set-up.
