233, again, but this time @6300 RPM

AFR conditioning and an intake = FTW.

SAE
233 hp
220 ft/lbs




Next on list
1.) Better intake design.
2.) AFPR, Ghetto timing advance
3. 100 octane
4.) UDP, (been in my trunk for about a year now, maybe I should install it)

I played with it every way from Sunday and it seems to like that set-up. I was on 91 octane. . I went too lean on one run, and it didn't like it. Better fuel + leaner AFR will helpfully get me a touch higher numeros. New appointment within a few more weeks.

I got some plans for the evening, but I have some Cipher logs to go along with these.

There seems to be a problem with my email, I don't see an email with your runfiles anywhere.....

I'll send them tomorrow. Me= out of town.

Seems as if the fuel issue was really holding me back. Couple of runs I saw a huge dip in power due to the lean afr. One thing though, the SAFC didn't hemorrhage, so that was a (+).

MAF logs vs HP/RPM look to be interesting. IAT's were in the 90-100*F range.

Even w/ my Z33 injectors, I don't need to take much fuel out. I 'blame' TS for that. But maybe an AFPR will remedy this.

Corr%'s didn't exceed more than 4% (+/-). I switched back from -3% --> +4% over a couple hundred RPM, and the power curve freaked.

It was quite fun. Also compared my runs w/an 03 Z33, curves were identical. Z had race cats and some modded intake shtuff.

Things in the upper 6k's seem to be suffering from my exhaust set-up, but, I'll trade off a few hp's for the mellow tone I have.

My last 233 was on pure 100 octane, so, there's power to be had from that, and these runs show my best and worst.

No intake (stock airbox) and then the last, highest, run was the average of the 5 I did.

Back to the drawing board on the intake. I have a plan, so that can be taken care of quick and easily after a quick trip to HD or Lowes.

Well, i was more impressed at the peak HP @ 6300 RPM thing than anything else. Was the HP peak higher last time?

My best is 233, ever. But last time, on race fuel, the overall curve was stronger, but it went dead after 5600 (peak).

Here's my previous best vs this one.

Also, no one really mentioned the fact that I have a lof RPM(I'm an auto) resolution


Previous best. Race fuel FTW.




And here's my 1st run ever. I couldn't dyno worth arse. lol

2nd gear in A33B = FTW. I think it's because Nissan didn't want them mofuggin old people having a stroke when said gear down shifted.

They are, verified by Cipher. 2nd gear does seem to lose a little down low(tq, vs 3rd gear) But the curve is smoother, and doesn't get me as nervous (13.7 AFR @ 6750, 130mph+ ) Honestly though, that 100 octane really does help. I'm trying to boast my theory, and hopefully in a week, I'll have another set of runfiles to back this said theory w/ timing logs.

Ya, Floored it @ 60 MPH, shifted into 3rd, had some lock up tq converter status.

I'm looking for a larger air filter, and am going to get rid of all said reducers and such in the intake line and have something a little better for massive RPM breathing.

For some creepy reason, my AFR data look better (flatter) than this DJ data ...

But these are my runs today.

You really need 100 octane? From what I've seen we can run full timing advance on both VQ30's and 35's at 93/94 octane. Race gas no helpee, only burn more slowly. Ask Jime, he'll tell you the same thing based on his dyno testing.

And IIRC you're at a higher altitude = less dense air so even less risk of detonation. So if you're getting more power out of octane then I'd wonder if you're getting timing too advanced/pulled by the KS normally on pump gas...

For some reason, higher octane really helps me.

My UNC #'s are ~ 190.

In fact, as you stated, I run much less risk of detonation, but, when I went lean,I did lose power( large dip/detonation) so, that means I could tune more lean and get more power w/beautiful fuel, but that is yet to be determined at this point.

Thanks for the input Dan D.

Now that I think about it we've probably talked about this on PM haven't we.

Well I dunno, something just seems a bit fishy to me, I mean I would think you'd be able to run the same/lower octane than the rest of us... Good job on getting the peak up to 6300 though.

What I need to do is log some air usage(gm/s) parameters and see how lean I can go using this stuff (better octane) before I dyno again.

This way, it can be seen/noted/documented just how much it affects engine efficiency.

I'm thinking of tuning rather aggressively (14.0 - 14.2) and logging/noting how it affects gm/s #'s.

Previous best. Race fuel FTW.


And this time you had the Z33 VTC maps and last time you didn't right?

That's right.

My power curve was identical to another Z33. I had a bit more after 6300 than he did, but under the curve, they were identical (+/- 0.5%)

Ok, So I'm looking at your previous best dyno, and my current (non corrected STD, no runfiles FTL)...

(these are from my ubber eyeballing guestimations- ricer math , so give or take 3whp for the #s, and +/- 7WHP for the Diff due to different correction factors, etc... I dont care so much to compare your power to my power, since the #s are not on the same correction, Im just comparing the shape of the power curve)

RPM= You/ Me/ Diff (Me vs You)
3750= 155/132/ -23
4000= 166/158/ -8
4500= 187/198/ +11
5000= 217/221/ +4
5500= 233/236/ +3
6000= 227/231/ +4
6500= 210/209/ -1

I would say that due to your ECU's timing, that explains the power difference below 4000. It would be great if the shift_control device that Grey99Max and Streetz use could work on the 5.5 gens (could it? hmmmm ) so you could actually be able to dyno from lower RPMs.

At 4500 I have more power, but thats probably due to the amount of SAFC "timing advance" at that RPM, that's my richest point so it has -20% cor.

How much timing do I have? I'll find out next week. My collegue has a dataloger device. I just need to rig up a cigarette lighter again (currently using that hole for engine start button [weeeerd]) so he can power up his laptop.

I think that after 5k we're pretty even. You held power on that setup slightly better than me closer to redline, most likely due to VCTs' fully retarding the intake cams at that range.

You have an SSIM (or SSIM "equivalent" like me) correct? My previous dyno at redline I had ~180WHP, SSIM and catback and now redline (different dyno so different correction, but still) ~210WHP.

Congrats on the #s tho, and the new setup. Must run like a beast on the highways with long straight roads :-D

Nope, my previous, which you're comparing to, was prior to said manifold mod.

I hated my power up there pre manifold mod. I gained 40+whp with that and other mods from 6300 - 6550. As can be seen by the graph, I was @ 191 @6400 with ONLY headers, now I'm @ 231 @ 6400.

Like I said, with all my uber advancements I was able to gain 40 whp @ 6550 vs my 1st run w/ only headers as my mod. See, the thing is, my previous best (210 @ 6500) was with the stock mani. So, perhaps you may have a bottleneck somewhere. But, your logs might tell a big story.

She sure does. Currently working an getting that peak higher value wise and even more to the right, if possible. Work commute everyday is 50 mi and 65% is all highway FTMFW.

Yea I was comparing to the previous best. Damn man, so that was with stock IM... that hurts me, LOL.

My top end will never be as great as a 5.5 gen's, as I dont have VCTs to retard my intake cams up there. But I didnt think it was THAT much of a difference. My SSIM on a 5spd matches your stock IM results on an auto.. ouch, lol. Perhaps some long tube headeers will assist.

Ok so your greater power on the midrange relative to mine is from the ECUs higher timing AND functioning VI.

Siiiiiiigh... I wasnt going to mod my car anymore, just fix it and save up for the next car. Now you have me concidering headers and more SAFC "timing advance" to see what I can get up there in the RPMs , lol
