View Full Version : Matt visits the dyno

Strapped her to the rollers today to get it tuned.
Numbers are a bit on the low side since it was a Mustang Dyno, which generally reads lower than a Dynojet.
Plus, I ran under some fairly restrictive conditions - a stock airbox, heavy wheels/tires and a pretty warm day (temps hovering around 90).
Dyno operator says I need hotter plugs, and to use copper-core (stay away from iridiums). We'll see.
NO KR until we ran hot and the PCM triggered the CAT coolant protection.
Anyway, we ended up with 194WHP and 196WTQ, which I figure is right around 240HP/245LB-FT at the flywheel.
While the peak numbers aren't earth-shattering, the amount I picked up down low was pretty incredible (over 20WHP at some points). Car scoots pretty well.
Not a bad increase for only having a ported top-end, mild cam and headers.
Track times when I get around to it.
Ben hates my seats.

Neat. What gear did you do the pulls in, and how did you keep it from downshifting?

Your seats ruined my ass today. With the COT turned off, it would have kept all that timing in there too, but I have a lot to learn on OBD2. Let me know on the MPG when you fill it back up. Really curious what the spark timing and VE tune did for that.

2nd for most of the tuning, because 3rd was causing the COT issue. Did the last run in 3rd to compare with the 1st run. HPtuners lets you select what gear your transmission is in.

To give you an idea of what we gained (for peak numbers anyway), the very first pull we did in third gear returned 170WHP/168WTQ. Last run (also in third gear was 194WHP/196WTQ). I'm pretty happy.
Next up - a 200 shot of giggle gas!
Maybe not.....not quite ready to divorce the transmission.

HPtuners lets you select what gear your transmission is in.
On mine it would still downshift. It works the same as moving the shifter to 3 or 2 or 1. That only stops it from shifting any higher than that gear, but it still downshifts if TPS vs. RPM is met.

Pretty damn good, that's about 54 WHP more than what a typical stock engine does, iirc, and within 10 of what I got with the basic Magnuson kit.

ACDelco plugs are only available in one heat range higher in a copper plug..

nice matt. 7 more ponies than i got. i want to re-dyno this fall. :)

Thanks for the positive comments.
We were hoping to hit that magic 200WHP number, but I picked up a new saying - "Go to a Dynojet for numbers; go to a Mustang Dyno for a tune."
Speaking of which, here's the dyno sheet for anyone who cares:

This car wants lots of fuel and timing.
You will see the dip in HP and torque, which is where the blip of KR (1 degree) showed up due to the CAT overtemp protection.
The cam makes power all the way to 6000RPM.
We only saw about 19 degrees of WOT timing on this run due to running so hot.
We'll see if hotter plugs make any difference, but I'll probably run it at the track first before changing anything.

i can't wait to see some track times, should hit 14s pretty easily.....

you know what you need? MSD ignition I bet that you help.
other than that I think it did really well on the dyno for #'s for the small amount of stuff you did to it

MSD coils are pointless and the DIS-4 will only help a little with MPG.

Nice video, atleast some ppl are putting work to our aleros :). How much you got invested on engine mods so far??

Found a dyno place right around the corner from my place, after my tuning, I'm heading over :D

At least on the 3400.

hey matt, are you running a 65 mm throttle body? any work on the heads at all or is the p&p just on lower and upper intake manifolds. very interesting numbers-keep it up
edit-nvm i just checked out your cardomain page

And every single other GM car on the road as well, including your 4 bannger ;)

That's why my spark doesn't blow out anymore compared to stock coils, right? I can now run 0.038 gap without issue at 18 psi, yet before the spark would blow out at 15 with 0.025 gap. Maybe you haven't paid attention to the thread I made, or anyone who's used them.

It doesn't help a boosted 60V6 either. We have tested it in multiple vehicles within the 60V6 community, all with the same results. No hp. Smoother idle, better mpg, no power or improved track times.
Magnecor wires and proper plugs are all you need for these engines. I can't speak for the 4 cylinders, so I haven't bothered with your thread.

Not speaking to you; talking about Redog's uninformed comment that MSD coils on an LD9 yields no benefit.

Ben don't forget the MSD sticker, that adds about 75 HP by itself :lol:
Chris, you make NO mention of HP gains or anything on the sort. MSD igntion upgrade on a GM car does one thing. You open the hood and all your friends say "Whoa, that's tight"

That one has me a bit confused and I'd like to understand why that suggestion was made.
Nevertheless, I am not changing anything (even the stock paper air filter) until I get a baseline track run.

The gain comes from a reliable spark. You can't tell me that my car runs the same with it stumbling and sputtering versus smooth and powerful. I'm surprised with your background that you would talk down about having a strong spark. Everyone upgrades and adds to their fueling system and air induction, but ignores the ignition system. You need air, fuel, and spark to make the boom. If one isn't up to par, you make it so. I made my spark be able to handle the large air volume and turbulence it experiences. The proof is in the lack of stumbling under my old boost level, and also being able to now run a higher boost pressure still without it stumbling. And the ability to widen my spark plug gap (larger spark surface area). Last year at the track if my car jumped to 15 psi the spark would blow out and the car would stumble and shake down the strip, costing me time on the track. My car was shaking down the quarter mile when I ran 13.9 twice in a row, it was running like shit with all the weak spark failing to ignite the combustion mixture.
Now I can run a constant 18 PSI with spikes to 20-21 PERFECTLY smooth. So don't comment on shit you don't know about.

yea i don't get it either. i would think you want to go to a colder plug so you can squeeze as much spark advance as you can.
[ion] C2
08-24-2010, 05:35 PM
You want the plug to dissipate enough heat to prevent pre-ignition, but you also want it to be hot enough to burn off stuff so it doesn't get fouled out. Almost everyone uses one or two heat ranges colder of a plug on higher spark advance and/or boosted applications.
