I got some time to do some tuning but there is still room to squeeze out more.

Runs:

1. 233.3hp 230.0 tq
The AF wasn't very good on this pass. I had the SAFC-II too rich up top.

2. 240.7hp 230.3 tq
I adjusted the A/F some

3. 240.0hp 234.2 tq
I adjusted some more

4. 240.1hp 232.5tq
And more, it appears the car is heat soaking

5. I try a 6th gear top speed pass and confirm that I have a speed limiter. The car hits 151.5mph on the dyno. That's beatup, some of you guys are going to 157mph in 5th on the dyno with no speed limiter.




I let the car cool off and do some more adjusting...







6. 249.4hp 241.6tq



I am certain I can push it to 255whp with some adjusting at 6k to make it 13.5:1 instead of 13.0:1 A/F.

I will add scans and run files later tonight.

In the meantime, can someone provide me with some VQ30DE-K dyno run files? I think it will be an interesting comparison.

 

By the way... this is a 2002 6 speed Maxima. No power adders.

Mod list:

Modified Intake Manifold

Cattman 3.0 Headers

APexi SAFC-II

UR UDP

Ported stock airbox

17º base timing (14 is stock, 15 is stock spec)

Hot Plugs (+1)

Hollow OE Cat.

HKS rear section (axle back)

Bypassed TB coolant hose

93 octane pump gas

Stock B pipe

Fresh Amsoil 5w-30 motor earl.

VQ30DE earl filter

North Carolina air

Dave Brown Motorsports dynojet 248C





Thats all I can think of right now.

 

 

I call bs.






Nice work Matt!!! *crosses fingers for 255*

 

That dip in the A/F @ 6000rpm is my 255 waiting to happen.

 

peak HP at 6600 on a VQ35DE Maxima motor....looks like a DEK power curve :raises the flag:

E-mail me those runviewer files

 

Actually the peak would be at 6200 (over 250whp)if it was tuned to 13.5 there.

 

That is some very comendable work. congrats adn plus i hate that my vq30de-k will never reach 255 all motor.

Congrats!

What did you dyno stock? Your car can trap 100+ easily I bet.

 

wow, if you get 255 which you probably will, you will be at 300 chp! very impressive numbers. you going back to the track any time soon?

SAFC? The stock ecu can't handle the breathing mods? Damn nice numbers 249hp at the wheels is rocking!

 

I don't think it can. Lots of 350z are running lean from just adding a pop charger or headers. Some are getting into 14:1:1

 

It handles them fine but from what I've seen the VQ35's still run quite rich even with all the bolts ons. With all my mods from 5k-6600 Im runnin 12:0 a/f.

 

wow nice numbers. I guess you won't even need a TS ecu

 

Im curious to try out the IM at the track, I might have to get the ECU again to take advantage of the raised rev limiter where as before it wasn't too useful

 

You had your chance and you pu$$ed out. You shoulda listened to me before and tried it when you had the ECU that day at the track.



Mine ins't leaning out, it's acutally on the rich side for some reason. I had to take out over X% (6-10??) at 6400 to get it to 13.5 .

One thing that I havent mentioned is that I dynoed without my air filter. The reason I took it out is because I noticed it was VERY filthy and was probably killing power. On my drive home I immediately noticed that my SAFC-II was reporting over 73% MAF wheras before it would max out at 66%. Therefore I just dynoed more power than I had at the track when I was trapping 106mph.

Look for more than 106mph on street tires the next time I go to the track. The butt dyno definately feels the redline gains from my tuning session and Im usually reluctant to talk about the butt dyno.

 

 

sr20den: are you planning to go for the TS ecu for the raised rev limiter and then adjust with the S-AFC?

 

wow! Very Impressive Numbers!

 

Yes I need to rev to 7200+ now and get rid of my pesky 149mph speed limiter.

 

Wow, I almost missed this thread. Very nice. I noticed you don't have the big dip in power at around 3800 rpms. Is that from the new IM setup or because of the SAFC tuning?

Blu, you should have tried out the IM. I'd love to hear how it works for us auto guys.

 

It could be the VTC's or it could be due to the intake. In blu's other thread he mentions he is not completely done with it.

I am not completely familiar with VQ35 dynos, I just haven't spent much time studying them

 

I have some from an auto...send me your email addy.

 

sr20dne how did you mod your intake manifold im going to port and polish mine but i was curios about your mod im trying to polish my intake befor i tune my s-afcII controler also do you know if it will make any difference if you remove the air idler in the side of the intake manifold. your help appreciated

 

I would love to be making the same power you are right now. Your car is a beast imagine it with some JWT cams.

 

I am running the same mods as he with cams and minus the modifed intake manifold. I could only reach 241.4fwhp and a very low 218.1 tq. I dunno if the cams are worth it for the price and only a 12 hp gain.

Those are very nice numbers SR, I'd love to get my numbers to truly reflect the mods im running. I wish I could read minds to find out what you have done with your intake manifold...

 

What cams do you have? You're the first 2k2 we know of that has cams and is running.

 

JWT S1 cams.

 

I finally saw that in your other thread. I am more interested in the Nismo cams.

 

i guess you're probably expecting to run in the mid to high 12's now?

-vq

 

Not yet .

 

nice numbers...to think im just 500 lbs. away from running into the 12's myself...

 

You've got to get that torque up to do it.

 

dont be so sure...we have different cars...notice how flat the torque curve is...

 

2001 acura = Tranny failure is definite , Nice try.......

 

ya im on my second one...so whats that mean...when i put a built one in i wont have to worry about that ...for now it's under warranty so who cares
