Grey's 3.5 dyno 226hp/202tq - Dynojet in KC

[grey99max]

Finally got to Revline Racing in KC to a few dyno pulls.

I actually got four - their wideband didn't work the first time. They use their own PLX and probe in your bung, not a sniffer, so more accurate. Evey run was made in third gear, taken to fuel cut, locked into gear by a Shift_Fast. We noticed that the first two pulls had a knee-dip at 6K, so I took off the new air inlet - made no difference. There were no run files available today. All runs were made with open cutout except #4 - notice 7hp decrease...

EDIT: Fuel pressure was 42 psi.

Run #1 printout was also out of ink, so it's dim.... Setting was SAE, smoothing = 5 for all pulls.

Pull #1:



Pull #2:



Pull #3




Pull #4: cutout was closed for this one.




I'm pleased - 226 hp and a decent curve... now let the fun begin..

Did you have the TQ locked during these dyno pulls?

Is the VI working? I believe power should go all the way to the top and not drop like that.

2k2 + top end isn’t that great actually.

Grey, you know what I’m going to ask… DRF’s please.

How does that bad boy feel? How do you have the VIAS connected?

Not this time -enough drama just getting these pulls done.... The cutout thing and the intake thing were enough changes for one day.

There is no VI - the intake has been SSIMed...

There is the same funny dogleg in each graph. ??? Could this have been the dyno? I watched and heard the dyno operator take it to the ECU fuel-cut at 6650 on each pull, but the graph RPMs stopped before that on each graph. I wonder if the DRs on the front were slipping at the top - third gear pull to redline could do that. I've seen other cars do it - even to the extent of making lots of tire smoke.

With the 3" cutout open, the car was really loud... Really loud.

Top-end power is plenty - when two stages of nitrous are coming back..

As I said, there were no DRFs available,

How does it feel? It's a beast on the street above 4K. No VIAS - it's SSIMed by *Z350.

Harold! w00h00!!!!!!!!!!!!!!

The drop in power after 6k is normal, I have it too. Its a cam-timing issue. Power up there isnt "all that" on the 5.5gens+, and its even more noticeable when using a 3.5 with 3.0 ECU and timing equipment. So no, I doubt your tires were spinning on the drum if they strapped down the car properly.

Yes SSIMs dont really kick-in until 4k.... and you sure as he!! know when it kicks in LOL... especially with BOOST! *hint hint Harold *

Thanks - it's good to know that - it just seemed quite abrupt. Plus their dyno charts didn't match what I know is an accurate fuel-cut RPM.

Boost, huh? Funny - yesterday I met the guy Chuong, who runs Revline, who makes very fast 9 sec. turboed Hondas for the street (and ran into another guy there with a supercharged Honda NSX I beat before). He was impressed with the old max, and offered to help me build it up some more... It's obvious that a good engine management computer would make some more HP. They had at least 6 engine builds going on there Saturday. I think that I'll look into what they can do for me...

If they charge you more than $550 for an "engine management system".... turn it down, lol. For that much you get an Emanage Ultimate and do all you need to do with that. Not only that, but for YOUR particular realm, you dont need any timing ADVANCE, if anything you'd need RETARD. So really, EManage Blue would be just fine, which can be had for $150 shipped or less used.

Nice play on words there...

I guess I need someone to convince me that I need an Emanage of some type. I think the timing from the stock ECU is fine - 17* advance at WOT is about right. I do have a couple of datalogging programs that show me what just happened. If A/F will be tweaked by the nitrous jets and regulated fuel pressure (42 psi now) then what can I do with an Emanage? I admit I don't get it.

When are you and streetz going to settle who is the baddest RMT Maxima in Florida? And are you selling tickets? Or videos?

Nice runs.

In for the 1/4 mile times.

Maybe this Wednesday at KCIR - or Heartland if the weather holds. Maybe - more rains are coming...


I have no idea what the car will do NA..... maybe 14 flat?

Well now we have a 3rd contender for the title. The white Maxima on my sig is officially RMT'd as of last week. Basically, we have 3 turbo maximas shooting to break into 12s. That wont be for another few months at least. I gotta pay tuition for summer and.... it aint cheap :-(.

All piggybacks are simply a way to bring out more of that potential power in your setup by doing a fine-tuning. Weather or not its worth it to you, is really up to you. All motor on the 3.0L I gained 7whp/6wtq. Gains would of course differ from setup to setup, no way to guarantee a certain amount of power from tuning due to that.

As raw and dated as the SAFC is, it has helped quite a bit, especially re: larger MAF housings, for me anyhow.

I've seen you talking about using larger MAFs - you need something to compensate for this, right? I'm running really rich at WOT, so maybe a larger MAF would lean out the engine a bit ??

It helped him. As long as you can monitor AFR, trial & error would be fine.

Stock MAF Housing VS Big Bore MAF Housing (76.2mm ~ 3") Technical Discussion


That is w/no AFC.

Keep in mind, SAFC's are cheap and very easy to isntall.

Yes, I've got a PLX R-300 installed now. So I need to look into a SAFC as my first step into real tuning ?? I'm so used to slamming more nitrous that I've never thought about AFC tuning..

Thanks for the feedback. 'ppreciate it..

IMO, it's still a very raw way to do things. But like I said, it makes larger MAF housings much easier. Considering the success you've had in the past w/o one, it may or may not help. Considering what is on the market these days, it does pale in comparison (SAFC).

I too have an R300, I have tapped the important wires from ht ECU and have extended each wire (MAF/ECT/TPS/RPM/MPH) with a single elad wire so it makes a SAFC/PLXR300 install / reinstall VERY easy.
