06 Altima SE-R 5spd Auto Dyno (Untuned)

[Juiced SE-R]

Well I finally made a trip to the dyno last Wednesday to see where my afr was, and to see what I was putting to the ground. Its been a while so I was hoping for some decent numbers. I recently installed headers and y-pipe and a walbro 255. I went as soon as I got off of work and put the car straight on the dyno so it was a little warm plus it was a little warm here in Oklahoma but oh well. I guess I’m happy with the numbers for now. I will get it tuned here in a few weeks and see what it does then.

Motor (Back to Back Pulls)1st Pull 237.60 whp 232.17 tq2nd Pull 227.60 whp 227.42 tq <---- Decrease maybe due to heat??

Nitrous (Back to Back Pulls)1st Pull 346.30 whp 368.30 tq (Bottle Pressure 950psi)2nd Pull 333.06 whp 347.18 (Bottle Pressure 910psi)

Hmm.. I think most stock SE-R's dyno'd at around 215-218 WHP... so in a perfect, cold engine setting, you gained about 20 HP from an

1. intake2. Headers3. y-pipe4. High flow catalytic converter5. full catback exhaust

however, in real world settings, with a warm engine, you only gained about 10WHP... so that's like $2000 worth of bolt ons for 10 HP?????

^ If you knew anything about tuning or how to look at a graph then you would know why my numbers are the way they are. AFR as rich as it is tells the story but you didnt even look at the graph so that shows ignorance on your part. Do your homework on diffrent types of mods/tuning and afr's for these cars and then get back to me. But my car isnt built for N/A numbers so its fine with me. I have something that makes up for that in a hurry

I don't claim to know much/anything about tuning... but I'm looking at pure numbers, and I'm trying to figure out why it looks like there's only a 20Hp gain with all of your bolt ons... (nitrous aside obviously)

I hear a lot of claims about how much HP people get from bolt ons (+13 from headers, +5-8 from cat back exhaust, +5 from high flow cat, + 5 from intake, +13 from Y-pipe, etc) Now I know many of these claims are exaggerated, but let the companies tell it and I would expect to see like +40 or more HP from all the bolt ons you have ... so if you can, please explain in your opinion why there seems to be such a low increase in WHP with all of these bolt ons. As I stated, the second pull looks more like the type of condition the engine would be in under real world conditions, i.e. warmed up.... that's only about +10 HP difference from stock SE-R readings

People on the forums spend a lot of money on bolt ons, however from the looks of your dyno results, the gain in HP is not very impresive at all for what appears to be thousands of dollars worth of bolt ons. So for the folks here considering getting some of these mods, a little bit of an educated explanation could go a long way in helping folks decide which mods (if any) they want to do to their car! My post wasn't meant to be a slight at you, your car, or your mods,,, I'm just trying to figure out why the numbers look lke they do.

The car is very rich period there are no ifs ands or buts about it and thats caused by my Walbro 255 which most people don't have or need for that matter because they aren't doing what I'm doing with their cars. With afr's in the 11s on motor and 10s on the spray there is power there left to be pulled out of the car. "IF" I had the stock manifold with a block off plate I could garuntee another 10whp and thats why alot of people do not like the Kinetix because they think it should be used for N/A applications and thats not what it's made for and they can't afford it so then they bash it not really knowing the purpose of the part. So say I had 10whp more 247whp untuned would be very respectable especially from an automatic. Alot of people look at PEAK hp, your car does not make peak hp all the time, the thing that needs to be looked at is under the curve, thats where your gains come from but I'm not gonna sit here and post up all of my graphs showing the gains underneath the curve because thats pointless. The factory freaks out there that have headers and that are tuned may put down just a little over 260whp and most of those are 6spds, so when my car makes 250 or a little above that here in a few weeks tuned then I will be right where I should be for an automatic. The car will make at least 250 on motor, and with my bottle pressure around 1050 and a good tune it may make close to 400whp and maybe over 400tq we will see what happens.

good response, much better than the first... very informative you must remember, everyone here may not know as much as you do in your area of expertise, so sometimes you have to break it down for us less educated folks in the tuning world!

Explain Kinetix and AFR, its help me make sense of everything

Well I didn't mean to come off as an a$$ but I hate it when people bash on other people, don't give any credit when they don't even know true facts or whats going on, not saying thats anyone thats posted in this thread yet but there are always haters out there so thats why I was so quick to the defense so my apologies.

Ok as far as tuning goes, optimal afr for a VQ35 is 13.1-13.3 and around 12.8 above 5000rpms, but then again every car is diffrent meaning you need to see what afr you car makes the most power at while staying safe with it as well. On motor the car is in the low 12's and on the spray it drops down to 10.1 which is REALLY rich so theres room for improvement bot N/A and on the juice. Before installing my headers I was tuned on a 100shot with my afr around 12.8, but now I'm gonna try and aim for lower 12's just to stay on the rich side and be safe. The Kinetix is a pretty manifold yes, but it doesn't give the best gains N/A, the stock manifold with a block off plate ($60) is the best 10whp mod you will ever get for the money. There are threads everywhere about people that have done that mod and even some showed on the dyno a 10whp gain just from the block off plate. So thats why I said if I were to have the stock manifold with the plate then I would probably be seeing in between 245-250whp untuned. But since I have the Kinetix my numbers are lower N/A than most expect and thats ok with me because I know why the numbers are low and most others have no idea, all they say is the numbers are low. But like I said I spray and thats what the car is built for so thats why I have the Kinetix on there. Six equal length runners distribute nitrous VERY evenly across the board giving me more hp than what is normally recommended to the wheels and thats why I love the Kinetix. I am going to be tuning the car later this week so I will update the numbers once it's tuned.
